电热水壶手柄塑料模具设计说明书
摘 要
本次设计主要是针对电热水壶手柄的模具设计,通过对塑件进行工艺的分析和比较,最终设计出一副注塑模。该设计从产品结构工艺性，具体模具结构出发，对模具的浇注系统、模具成型部分的结构、顶出系统、冷却系统、注塑机的选择及有关参数的校核、都有详细的设计。通过整个设计过程表明该模具能够达到此塑件所要求的加工工艺。根据设计的主要任务是电热水壶手柄注塑模具的设计，以实现自动化提高产量。针对电热水壶手柄的具体结构，该模具是侧浇口的单分型面注射模具。通过模具设计表明该模具能达到电热水壶手柄的质量和加工工艺要求。 同时，在设计过程中，通过查阅大量资料、手册、标准等，结合教材上的知识也对注塑模具的组成结构（成型零部件、浇注系统、导向部分、推出机构、排气系统）有了系统的认识，拓宽了视野，丰富了知识，为将来独立完成模具设计积累了一定的经验。

Abstract
This subject is mainly directed againstElectric kettle handle die design, through the technology of plastic parts for analysis and comparison, the final design an injection mold. The subject from the process of product structure, the concrete structure of mold, the mold system of casting, mold forming part of the structure, the roof system, cooling system, the choice of injection molding machines and related parameters of the check, have the detailed design, And the establishment of a simple mold processing technology. Through the entire design process that the mold plastic parts can achieve this by the requirements of the processing technology. According to Title Design's main task is to handleElectric kettle injection mold design. That is designed to produce an injection mold plastic partsElectric kettle handle products to improve the automation of production.Electric kettle handle for the specific structure, the die is the side gate of the single type of injection molds. Through die design show that the mold can achieveElectric kettle handle the quality and processing requirements. At the same time, in the design process, through the consult massive material, the handbook, the standard, the periodical and so on, unified on teaching material's knowledge also to injection mold's composition structure (formation spare part, gating system, guidance part, ejecting mechanism, exchaust gas system, mold warm governing system) to havesystem's understanding, has expanded the field of vision, has enriched the knowledge, will complete the mold design for the future to gain in certain experience independently.
