摘 要

 本文主要介绍了塑料赛马汽车烟灰缸盖注射模的设计过程。通过对烟灰缸盖的分析，完成了模具的方案设计，包括分射机的选择、型面的位置确定、型腔数的确定、浇口的选择等。详细地设计了模具的成型件、塑件脱出机构、侧抽芯机构、浇注系统和冷却系统、型芯和抽芯的形式以及模架的选择等，并对主要零件,比如型腔尺寸，凸凹模尺寸等进行了强度校核。其中，侧抽芯以及滑块抽芯是本次设计的难点。由于烟灰缸盖的两个侧孔，普通型芯无法完成脱模，这就需要计算侧抽芯机构，侧抽的导柱及滑块的设计是其中的重点；烟灰缸盖的背面有挡板阻碍正常脱模，因此采用滑动型芯，既可解决脱模的阻碍，又可以将塑件顶出。通过受力分析及计算得到斜导柱及滑块等的尺寸，解决本次设计的难点。

Abstract
 
 This paper introduces race car ashtray covered plastic injection mold design process. Ashtray covered by the analysis of the program completed the design of mold, including the choice of sub-shot machine, determine the location of surface, to determine the number of cavity, the choice of gate. Detailed design of the mold pieces of molding, Plastic extrusion bodies, the side core pulling bodies, cast system and cooling system, core and core-pulling, as well as the form of the choice of mold, and the main parts, such as cavity size, convexity Die size for the intensity calibration. Among them, the side core pulling, as well as core pulling the slider design of the difficult times. Ashtray cover as a result of the two side holes, the general release core can not be completed, which requires calculation of the side core-pulling mechanism, side draw and the slider guide the design of columns is one of the focus; ashtray baffle the back cover impede the normal release, so the use of a sliding core, it will resolve the release of the obstruction, and can top out of plastic parts. Calculated through the mechanical analysis and oblique derivative such as columns and the size of the slider to solve the difficulties of this design.

Key words:  Design of plastic injecting mould ；Surface; Core
