中文摘要

注塑模具是在成型中賦予塑料以形狀和尺寸的部件。模具的結(jié)構(gòu)雖然由于塑料品種和性能、塑料制品的形狀和結(jié)構(gòu)以及注射機(jī)的類型等不同而可能千變?nèi)f化，但是基本結(jié)構(gòu)是一致的。模具主要由澆注系統(tǒng)、成型零件和結(jié)構(gòu)零件三部分組成。其中澆注系統(tǒng)和成型零件是與塑料直接接觸部分，并隨塑料和制品而變化，是塑模中最復(fù)雜，變化最大，要求加工光潔度和精度最高的部分。

對(duì)此次放大鏡無(wú)多大要求，它的整體尺寸不大，但要大批生產(chǎn)，為提高生產(chǎn)率，降低成本，故采用模具成批注射生產(chǎn)。并且該產(chǎn)品為放大鏡要透光，所以材料采用聚苯乙烯（PS）做為材料。

對(duì)于澆注系統(tǒng)和成型零件的設(shè)計(jì)；澆注系統(tǒng)是指塑料從射嘴進(jìn)入型腔前的流道部分，包括主流道、冷料穴、分流道和澆口等。成型零件是指構(gòu)成制品形狀的各種零件，包括動(dòng)模、定模和型腔、型芯等。

此套放大鏡模實(shí)現(xiàn)部分機(jī)械操作自動(dòng)化，澆注系統(tǒng)采用普通流道，進(jìn)行一模二腔注射。頂出機(jī)構(gòu)由2條型芯和一條推桿頂出，型腔分動(dòng)模型腔和定模型腔。

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.
