题目： 锥齿轮注塑模设计

摘 要

塑料齿轮在玩具、仪表等场合广泛被应用，本次设计是基于工件材料分析、注塑工艺性分析及模具设计，以锥齿轮注塑模为主线，综合了成型工艺分析，模具结构设计，最后到模具零件的加工方法，模具总的装配等一系列模具生产的所有过程。在设计该模具的同时总结了以往模具设计的一般方法、步骤，模具设计中常用的公式、数据、模具结构及零部件。该注射模最显著的特征是避免了传统的脱模方式。该模具结构设计简单可靠，加工装配方便。

首先，简要介绍了现今模具行业的情况和未来有可能的发展趋势，以及限制模具发展的因素。

其次，对工件进行了工艺性分析，确定了模具设计的整体方案。根据塑料模具设计手册和相关经验公式进行了必要的计算，根据计算结果选用了注射机；又进一步完成了标准件的选择和对非标准件的设计。

最后，完成了模具的整体结构设计。

Bevel gear injection mold design

Abstract: In this paper, based on the mouth of the bottle Cypriot injection molddesignand process analysis, to the mouth of the bottle Cypriot Diemain line, the Integrated Process analysis, mold design of the structure, the last to die parts machining methods, the die assembly and a series of mold-all process. Can be good learning Zhiyong results. In the design of the mold while summing up the past die design the general methods and procedures, commonly used in the die design formula, data, structure and mold parts. Previously studied the basic courses to integrate, integrated into the design of this, the so-called good use.

The first part briefly introduced mould industry and the current situation in the future. Mentioned the factors restricting the development of mold.

The second part of a process of the workpiece analysis, mold design package. According to plastic mold design manual and the relevant experience of the formula necessary, according to results of the injection machine used. Further completion of the standard and non-standard choice of the design.

Part III completion of the overall structure of the mold design. Key
