摘要
注塑模具是在成型中赋予塑料以形状和尺寸的部件。模具的结构虽然由于塑料品种和性能、塑料制品的形状和结构以及注射机的类型等不同而可能千变万化,但是基本结构是一致的。模具主要由浇注系统、成型零件和结构零件三部分组成。其中浇注系统和成型零件是与塑料直接接触部分,并随塑料和制品而变化,是塑模中最复杂,变化最大,要求加工光洁度和精度最高的部分。
对此次放大镜无多大要求,它的整体尺寸不大,但要大批生产,为提高生产率,降低成本,故采用模具成批注射生产。并且该产品为放大镜要透光,所以材料采用聚苯乙烯(PS)做为材料。
对于浇注系统和成型零件的设计;浇注系统是指塑料从射嘴进入型腔前的流道部分,包括主流道、冷料穴、分流道和浇口等。成型零件是指构成制品形状的各种零件,包括动模、定模和型腔、型芯等。
此套放大镜模实现部分机械操作自动化,浇注系统采用普通流道,进行一模二腔注射。顶出机构由2条型芯和一条推杆顶出,型腔分动模型腔和定模型腔。
关键词 主流道 冷料穴 浇口 型腔 型芯
Abstract
Injection mold is given in the plastic molding to the shape and size of parts. Although the structure of mold species and performance of plastics, plastic products, as well as the shape and structure of the type of injection molding machine may be different from the ever-changing, but the basic structure is the same. Mainly by die casting systems, and structural components forming parts of three parts. Gating system and forming one part in direct contact with the plastic parts and products as plastics and change is the most complex modeling, the biggest change to require smoothness and accuracy of processing some of the highest.
The little magnifying glass on the requirements of the overall size of it, but to a large number of production, to increase productivity, reduce costs, and therefore the use of injection mold production batch. And the product is a magnifying glass to light, so the material used polystyrene (PS) as a material.
For the gating system and forming part of the design; gating system is the plastic nozzle into the cavity from the previous part of the flow channel, including the mainstream Road, cold cave, such as diversion channel and gate. Forming part refers to the shape of a variety of products constitute components, including dynamic simulation, and the cavity mode is scheduled, such as core.
This mode sets the realization of part of the magnifying glass machinery automation, pouring the ordinary flow system to carry out a two-cavity injection mold. Top two from the body core and a top of a putter, dynamic model of sub-cavity cavity cavity model and the set.
