摘要

结合国内国外压铸件尺寸精度和公差标准

分析了压铸件尺寸精度;针对铸件尺寸在模具中和模具外以及模具自身随温度的变化进行定量分析;结合具体案例

针对压铸件的几种缺陷如热变形、收缩、出模困难等对铸件尺寸的影响进行分析

提出了尺寸控制的对策。

Abstract

Combining dimensional accuracy and tolerance standard at home and abroad

dimensional accuracy of die castings was analyzed.The change of castings dimension in mould and out mould as well as mould with temperature change was quantitatively analyzed.Through practical product

effects of some defects in the die castings

such as thermal deformation

contract and difficulty to push out

on dimension of the die castings were described

and countermeasures were presented.
