摘要/Abstract

摘要：

分析某汽车弯管接头塑件的结构特点，结合其外观及性能要求设计了一副包含定模和动模抽芯机构，定距优先开模机构，开合模顺序保护装置和强制合模机构的复杂注塑模具，通过采用定模斜滑块抽芯机构成功解决了塑件定模侧向倒扣问题；针对塑件翻边结构上外观表面可能会出现纹路脱伤和碰穿孔批锋的问题，采用侧边分型斜向抽芯的方式解决。定距优先开模机构为抽芯顺序提供有效保障；强制合模机构避免合模时定模滑块与动模滑块出现撞模现象；两者与开合模顺序保护装置相配合保证了模具生产的安全性和稳定性。

关键词: 弯管, 侧边分型斜抽芯机构, 定模斜滑块抽芯机构, 定距优先开模机构, 开合模顺序保护装置, 强制合模机构

Abstract:

Based on the analysis of the structural characteristics of a plastic part in an automobile elbow joint and its appearance and performance requirements， a complex injection mold was designed， including a core⁃pulling mechanism comprising a fixed mold and a moving mold， a fixed distance priority mold opening mechanism， a mold opening and closing sequence protection device， and a forced mold closing mechanism. Through using a fixed mold inclined slider core⁃pulling mechanism， the problem in lateral undercutting of the plastic part was successfully solved. Aiming at the problems of possible grain peeling and impact on the surface of the plastic flanging structure， a method for side parting and oblique core pulling was adopted to solve these problems. The fixed distance priority mold opening mechanism provided an effective guarantee for the core pulling sequence. The design of a forced mold closing mechanism could avoid collision between the fixed mold slider and moving mold slider during mold closing. The combination of the two sliders with the mold opening and closing sequence protection device ensured the safety and stability of mold production.

Key words: elbow, side parting inclined core pulling mechanism, fixed mold inclined slider core pulling mechanism, fixed distance priority mold opening mechanism, mold opening and closing sequence protection device, forced mold closing mechanism
