摘要

　　　本文详细介绍了相机前罩注塑模的设计。主要介绍了浇注系统、冷却系统、脱模机构、成型零件等的设计方法及过程。他们共同组成一套完整的模具。

　　　浇注系统的设计是模具设计的一个重要环节，设计合理与否对塑件的性能、尺寸、内在质量、外在质量及模具的结构、塑件的利用率等有较大的影响。塑料注射模具冷却系统的设计，不仅影响成型塑件的质量，还直接影响生产效率。脱模系统影响塑件最后能否完整无且地离开模具。所以他们的设计合理与否直接影响一套模具的合格与否。

　　　本文对成型零件的工作尺寸、脱模力等都进行了详细的计与校核，保证了塑件的尺寸与装配。此外，本文还介绍了通过最大注射量的校核、锁模力的校核、注射压力的校核、安装尺寸的校核、开模行程的校核等的计算来选取适合注射机的方法。

Abstract

　　　This paper introduces the design of the front of the camera cover injection mold .Mainly introduces the gating system, cooling system, such as demoulding mechanism, molding parts of the design method and process。they form a complete set of mold together。

　　　The design of gating system is an important part of the mould design, Design reasonable or not to the performance of plastic parts, size, immanent quality and external quality and die structure, the utilization efficiency of plastic parts have a major influence. Plastic injection mold cooling system design, not only affects molding plastic quality, also directly affect production design reasonable or not directly affects a set of mould qualified or not. efficiency. Stripping system influence whether the plastic parts to leave without and complete mould.

　　　This paper of its molding part size, stripping force etc work makes a detailed plan and checking, Guarantee of injection by checking, clamping force of dynamicrigidity, injection pressure check and inste size of plastic parts and assdditiomblise. This paper also introduces the maximum amounallation size checking, open mold trip check calculation method of selecting suitable for injection machine.

Keywords: injection mold, gating system, cooling system, demoulding mechanism, injection machine
