摘  要

塑料制品具有原料来源丰富,价格低廉,性能优良等特点。它在电脑、手机、汽车、电机、电器、仪器仪表、家电和通讯产品制造中具有不可替代的作用，应用极其广泛。注射成 形是成形热塑件的主要方法，因此应用范围很广。

本次的毕业设计是六孔警灯的注塑模具的设计。  依据产品的数量和塑料的工艺性能确定塑件采用注射成形法生产，模具的型腔采用单腔平衡布置。本次的设计中不仅参考了大量纸质文献，而且在互联网上查阅资料，设计过程比较完整。

关键词： 六孔警灯 ，注塑模具，单腔

Abstract

Plastic products are rich in raw materials, low price, good performance and so on. It plays an irreplaceable role in the manufacture of computers, mobile phones, automobiles, motors, electrical appliances, instruments and meters, household appliances and communication products, and is widely used. Injection molding is the main method of forming thermoplastic parts, so it has a wide range of applications.

This graduation design is the design of the injection mold for the six lights. According to the quantity of the product and the technological performance of the plastic, the plastic parts are produced by injection molding, and the mold cavity is balanced with a single cavity. This design not only refers to a large number of paper documents, but also searches data on the Internet, and the design process is more complete.

Key words: six lights, plastic injection mold, single cavity
