手表盒盒底注塑模具设计

摘  要

本文主要介绍了手表盒盒底塑料件的注射模设计，其间要参考大量与塑料成型相关的资料和翻阅各种模具设计手册，并通过计算以确定模具的具体模具制造技术迅速发展，已成为现代制造技术的重要组成部分。如模具的CAD/CAM技术，模具的激光快速成型技术，模具的精密成形技术，模具的超精密加工技术。根据成型工艺要求，在原有塑料件的基础上介绍了其注塑成型模具的结构，阐述了模具设计要点及工作过程。首先要从塑料生产工艺上对所要设计的产品进行工艺的分析与计算，然后在分析计算的基础上并参看相关的资料确定成型工艺方案，再在此基础上进入模具总装配图的结构设计。在此基础上对注塑模具的主要零部件的尺寸进行设计与计算，期结构及尺寸，通过不断的计算与修改，并在指导老师的悉心关怀和耐心指导下进行不间断的反复修改，最终独立完成这次毕业设计。其材料为ABS。根据ABS塑料的工艺特性和产品的使用要求，分析了手表盒盒底的结构特点和成型工艺。本设计采用CAD技术进行模具装配图及零件图的绘制。对模具进行了成型零部件、浇注系统、侧向抽芯机构、推出脱模机构及冷却系统的设计分析。最后，完成模具总装图设计及主要零件图的绘制，从而确保模具结构的可靠性、合理性和实用性。

The watch box injection mold design

Abstract

This paper mainly introduces this watch box, plastic in the design of injection mould with plastic forming of to reference the material and paging through various       related mould design manual, and through the calculation to determine mold concrete die & mould manufacturing technology rapid development of modern manufacturing technology, has become an important component. Such as mould CAD/CAM technology, mould laser rapid prototyping technique, mould precise forming technology, mould ultra-precision processing technology. According to the molding process requirements, on the basis of the original plastic injection molding, it introduces the structure of mould design, expounds the key points and the working process. First production craft from the plastic to design on the product process analysis and calculation, then on the basis of the analysis and calculation and see related material sure molding process scheme, and on the basis of this total into the mold of assembly structure design. On the basis of main parts of injection mold design and calculation of the size of the structure and size, period, through continuous calculation and modification, and in guiding teacher of meticulous care and patience under guidance of uninterrupted repeated revision, eventually independent completed the graduation design. Its material for ABS. According to the ABS plastic technological characteristic and the use of products demand, analysed the structure characteristics of this watch box and molding process. This design USES the CAD technology for mold assembly drawing and component drawing. The forming of mould parts, gating system, side core-pulling mechanism, launched the demoulding mechanism and cooling system design and analysis. Finally, complete mold assembly figure design and main component drawing, thus ensuring the reliability of the mould structure, reasonable and practical.
