Procedure of debugging of the mould that the discussion moulds plastics, preparation before debugging, the technological working, debugging method and auxiliary project (CAE) of computer of the mould that should be done before transferring and producing are in the mold design and application while debugging. Keyword: Plastic shaping; Mould plastics the mould; the mould is debugged; Auxiliary project of the computer The mould designed according to the plastic products to mould plastics and try the mould was carried on the corresponding inject plane. Prove mainly whether the products that the mould moulds out accord with the design standard and quality requirement. Its purpose : First, the one that verified the moulds designed is very productive, the debugging of guaranteeing to inject the best craft parameter of shaping , corresponding inject mould passes the craft and confirms, one flows to revise and deal with three great stages with type. Should confirm the best process conditions according to the injecting machine and nature of making a material first, guarantee the supplies are good in plasticization, then under the process conditions confirmed , revise and flow one, make the supplies filled with evenly and energetically, through revising type finally, the external dimension of ntsguaranteeing to make one fulfils requirements. It is the foundations of technical management, production management, management and administration to try the mould; it offers initial data for the whole course of production. So, it is an important production ink of a plastic products factory that the mould is debugged, undertaken this important task by the technical staff. Debug personnel must is it mould plastics equipment, raw materials performance, knowledge and abundant practical experience, method of craft and structure, etc. of mould to possess, very much familiar with injecting the shaping craft, adjust and operate the transmission of the injecting machine freely, open the mould , not point out the existing problem of the mould to the structure of the mould through trying the mould , it is unnecessary to operate the computer to debug. If one makes a reservation and encloses size and injecting machine template and orients holes it is identical, spray nozzle spheroid R and spray nozzle aperture and mainstream each of mould and aperture is identical, a size, form flow, the size of the runner, such questions as the position, etc. are very easy to be found in front of trying the mould. Debug the question in the course, can react and deal with in time. Try the mould and experience to accumulate conscientiously for a long time, must help mold design and make the improvement of the shaping technological level. Following for the debugging course of injecting the mould: nts1、 the mould is debugged to transmit the procedure Mould plastics mould debug transmittance process to write engineering department mould high procedure form first, hand the production schedule or the development department of the new products to include in the work program, prepare raw materials, frock or spare part, inlaying one, tool, etc. in demand on schedule. Check whether the outfit of the moulding plastics machine is rational, can notify the mould debugged the department implements. 2, the preparation before the mould is debugged 2.1 drawings checking Mould must according to cooperate department or mould that production division assign debug the notice to the outside before debugging, begin to prepare, the first step is the verifying of drawings, there are two drawings referred to here, one products drawing that mould debug, one mould drawing, understand material that product require according to product drawing, geometry size, function and appearance require, for instance color spot, impurity, mark of connecting, getting sunken, can know the mould and debug the equipment selected for use according to the mould drawing, technical parameter and mould demand are identical, whether the tools and enclosures are complete. Transmit to a process after trying the drawing. 2.2 equipment checking ntsOil passage, waterway, mechanical movement part of checking equipment used, maintaining the equipment on request. Check the diameter of orienting the circle of technical parameter of the equipment, thickness of the minimum mould , thickness of the largest mould , moves the journey of the mould , interval of the pull rod , carries out the method sing, etc. should be all met and tried the demand of the mould , do well the preparation before driving. It should be compatible with returning the machine while producing to try the mould equipment, this is because equipment technical parameter and technical standard of trying mould products have connections, the changes of the fluctuation, pressure of temperature conspire, the empty time for circulation and the stabilities of machinery and hydraulic transmission, etc. will all influence the quality of the products. Adopt the equipment of complete collections of models strength to try the mould, adjust and change to the small inject plane which shuts the strength of the mould, the shaping condition may need changing. 2.3 materials are prepared Whether material, etc. meet the demands to check the specification, type, trade mark, additive, color mother of the plastic raw materials processed, should carry on the raw materials with big temperature dryly and deal with, confirm matching. ntsRaw materials should adopt raw materials that the drawing stipulate in principle, because the mould was designed according to the physics mechanics performance of raw materials, can use mobility to be fine too, apt fast solidification, hot stability kind raw materials, test the structure of the mould, make every position of the products, round angle, thick distribution situation strengthening the muscle of wall embody truly, can use as the reference of revising the mould. 2.4 moulds checking The mould is installed before the injecting machine, should check to the mould according to the mould drawing, so that pinpoint the problems in time, and repair the mould. Can check the external dimension of the mould according to the mould installation diagram, orient a size of entry of circle measurement , mainstream , the size of spheroid R cooperating with spray nozzle and entrance of the cooling water and export, height of the pressing plate cushion , width ,etc. Pour system, type of the mould, etc. need to open the mould inspection, after the mould moves the mould separated form model definitely, should pay attention to the direction mark, so as not to get it wrong while closing up. 2.5 cools the water pipe or heating circuit Put through the mould and cool the water pipe or heating circuit inspection, if adopt the hydraulic pressure or the motor one point of types, should put through the inspection respectively. nts2.6 tools and enclosures It is a specific purpose tool which tries mould personnel to try the mould tool, the splendid attire is in the portable toolbox , carry it conveniently, should allocate one set to debug personnel each one, tool relevant to the fact that try the mould is mechanical spanner , cushion , check the temperature of the mould to examine and count , check the card utensil of the quantity of the size of the mould warmly, check tool used for products ,etc., the copper that and operate is excellent, such indispensable equipment as copper slice and abrasive paper ,etc. It is very important that the ones that inlay one are checked, various kinds of to try on mould inlay piece including metal inlay piece, plastics inlay piece, rubber inlay pieces of card paper products inlay one, have for guarantee products out of shape spend finalize the design one,etc. after the shaping , must measure strictly , so as not to damage the mould , cause irretrievable losses, 3 , put the mould 3.1 hoist and mount The mould must take care while hoisting. Two people want close cooperation; try ones best to install wholly. If there are sides direction assigning to type organizations, under most situations, one is on horizontal level that slips, one is moved from side to side in the level to live. nts3.2 fastening After the mould orients the military organ that packs of the circle into injecting machine and encloses, close the mould at the extremely slow speed, enable moving the template and compressing tightly the mould gently, then have and compress tightly the board, compressing tightly the board according to the size of the mould, there can be 4-8 agglomeration. Top plate-with screws feet high with the national high to ensure top plate to compress modules feet. Check the parallel firm degree of degree, vertical degree, bracket of the mould, adjust the material tube and concentricity of the mould centre bore. 3.3 appear in the distance and carry out the regulation of the number of times Open the mould slowly after the mould is fastened, until the template no longer goes backwards, is it carry appear position of pole to regulate , make it appear board and move mould base plate have 5mm the above-mentioned interval not to carry, so as to ensure that can carry out the products without damage mould . Is it happen number of times make according to the needs of products , it is all right for one to appear , can appear many times too to carry, can choose to carry out the number of times in the injecting machine operates the panel , for depending on carrying exerting oneself and making the coordination that the strength of the mould realize ntsreleasing the core organization to work, so as to ensure movements start-stop, making a reservation , journey is correct, so as to avoid the phenomenon of interfering. 3.4 regulation of locking the elasticity of the mould Locking the elasticity of the mould regulates suitably, should is it overflow material to prevent, as well as person who guarantee proper to exhaust, for needing the mould heated, should correct and close the elasticity of the mould after the mould reaches the temperature stipulated , as to shutting the mould organization all-hydraulically type, the elasticity of locking mould only observes whether the mould pressure of the lock is within the range of craft booked, as to the thing that shut the mould organization , can differentiate according to the size or experience of the mould strength of the lock in hydraulic pressure pole type. 3.5 moulds are protected and regulated low-press. Finish models elasticity of the lock after adjusting tentatively, in order to guarantee the mould work piece safety inspection, must orient the mould, select the low-voltage starting point that protects, then under low-voltage protective action, with slow speed close mould most, adjust journey switch, make mould the person who divide at the alternate 0.2-0.5mm, low-voltage protective action is over, test repeatedly, guarantee that it is reliable to protect low-press sensitively . 4 process conditions are fixed ntsAccording to processing the plastic characteristic , according to the craft parameter recommended , fetch the craft parameter relatively value reselected first , then adjust while the mould is high. Tube and spray nozzle temperature between 4.1 differentiating machines. According to melting material plasticization quality, mainstream one of regular template uses the lower inject pressure to break away from the spray nozzle , enable melting the material to flow out from the spray nozzle slowly, observe the material and flow, if without hard one, the bubble, such defects as the silver silk , changing color ,etc., the material flows smoothly bright, the tube and spray nozzle temperature of proving machine are more suitable, can begin to try the mould , on the contrary , need to carry on proper adjustment. 4.2 choices with material way There are three kinds as follows of reinforced ways of injecting machines, choose the suitable reinforced method according to the supplies and mould situation. First, before feed in raw material, namely each inject later, reach plasticization at the time of capacity of requiring, retreat after injecting one , until the next job circulation advances while beginning , make spray nozzle and mould keep in touch, injecting , this law is used in the temperature of the spray nozzle waywardly , carry and press relatively ntstally, prevent the occasion of the backset current . Second, after feed in raw material, namely not after not injecting after not injecting by it retreat it go on in advance work plastics, wait the next job circulation begin , is it is it is it inject to go on to go back to reply , law this used in spray nozzle to be temperature wayward processing the crystallization plastics. Third , feed in raw material regularly, namely during the whole shaping cycle , spray nozzle and mould have been keeping in contact all the time , is the commonsense method at present, suitable for plastic temperature range relatively wide shaping, spray nozzle temperature apt occasion that control. 4.3 regulation of injecting quantity Person who inject pour into supplies amount of mould one, it including plastics amount flow supplies amount of the dish, the feeding in raw material amount is regulated through the reinforced device of the injecting machine, the end is subject to that try the result of the mould, the injecting amount should seldom exceed 80% which injects quantity of injecting machine. 4.4 plasticization ability adjusting Plasticization ability root regulates the rotational speed of spiral shells pole, moulds and carries pressing and material tube, the temperature of the spray nozzle in advance. These all get in touch and ntsrestrict each other each other three times, must coordinate and adjust , the whole plasticization time should not exceed products cooling time , otherwise lengthen shaping cycle . The range that the rotational speed of spiral shells pole regulates is slightly bigger, but cant go beyond the range with required craft, rotational speed in the best working range selecting the rotational speed of spiral shells pole of the injecting machine for use, in order to reduce the fluctuation of the rotational speed of spiral shells pole. Control rational moulding carrying pressing in advance in the plasticization in advance, having so that the gas in the supplies is discharged, improve plasticization quality, it is decisive to carry plastic performance and relevant crafts parameter that the level pressed is processed, it is generally 0.5-1.45MPa, the plastics to that high viscidity and hot stability are bad, should mould carrying pressing in advance with the rotational speed of slower spiral shells pole and lower one , to in viscidity not low and the fine in stability plastics more, last spiral shell pole rotational speed and getting more high and moulding not if carrying , pressing in advance slightly not quicker, but should prevent melting the material and the saliva phenomenon flows . 4.5 injects the pressure to regulate It is thick according to processing the products form, wall, the structural design of the mould, such parameters as plastic performance, ntsetc., can choose the pressure of injecting and inject the speed in advance. While beginning, choose the smaller inject pressure in principle, wait for the temperature of the mould and reach the craft parameter range of the demand , observe and melt the material and fill the situation of the mould , if fill on the mould insufficient and having other corresponding defects , rise and inject the pressure gradually , in guarantee to finish filling on the mould cases , should try ones best to choose the lower manometer , so can reduce the mould strength of the lock and consumption of reducing the power . 4.6 injects the speed to regulate Person who inject at a high speed slow to inject rapidly generally, as to the thing that the small moulding one of area of shaping of thin wall, adopt and inject at a low speed. The shear correctly of some plastics is very sensitive in speed, it should help to melt the material to fill on the mould and prevent melting the material to go bad to inject the control of the speed. At high speed under and not at a low speed, should adopt at a low speed injecting (strengthen glass fibred except). 5, the debugging course of the mould Inject the mould and debug and divide the following several step mainly. 5.1 try the mould operation mode The operation of the injecting machine generally has manual, ntssemi-automatic, three full-automatic ways. Generally adopt manual way, so that the control and adjustment of the relevant crafts parameter while trying the mould, once go wrong, can quit work immediately. 5.2 pressures, time, temperature adjusting While trying the mould, have and choose low-pressure in principle, low temperature, inject shaping under the longer time condition, then adjust according to pressure, time, temperature and priority order. The influence that the pressure changes is reflected from making quickly, so, regulate the pressure at first, only when regulating the pressure invalid, the ones that consider the supplies are heated time, improve the plasticization result of the supplies , if consider improving temperature invalid, because the temperature of the supplies reaches the new balance and passes about 15, cant reflect from making one at once , so should wait patiently, temperature cant rise very high , in case that the plastics are degraded over heatedly. The shaping cycle while trying the mould is relative
