AI Technical Summary
[0004]本实用新型实施例提供一种两次脱模机构及模具，以解决现有技术中一次行位镶件和二次行位镶件在脱模的过程中与支撑座的移动方向相同，一次行位镶件后移的过程中会拉扯并损坏塑料制品的倒扣孔的技术问题
[0014] In this invention, the demolding steps of the two-stage demolding mechanism are as follows: the support base first moves the first insert backward in the horizontal hole, and the first insert moves the third insert downward in the vertical hole through the mutually abutting first and second inclined surfaces, thereby achieving the demolding of the third insert; due to the elastic force of the elastic element, the second insert remains stationary during the demolding process of the third insert; after the third insert is demolded, the support base moves the first insert and the second insert backward again until the second insert is demolded. In this embodiment, the two-stage demolding mechanism can achieve two demoldings, and the direction in which the third insert moves during the first demolding is perpendicular to the direction in which the second insert moves during the second demolding, thus preventing accidents such as pulling on the undercut holes of the finished model during the demolding process of the third insert, ensuring the quality of the finished model; furthermore, the two-stage demolding mechanism has fewer components, a simple structure, and low cost.
