Design of Demolding Mechanism and Injection Molds for iPad Brackets
摘要
Abstract
To overcome a demolding difficulty during the injection molding process for a stem-bracket part for iPads,three types of demolding mechanisms were designed.In these mechanisms,a bevel slider core pulling mechanism was adopted for a side simple structural feature,a small cylinder slide block core pulling mechanism was adopted for a deep hole feature,and a combined core pulling and demolding mechanism was adopted for the complicated central position.In the case of design of the combined mechanism,a die-bending pin-driving slider mechanism was combined with the three synchronous linkage slider core pulling mechanisms driven by a rear mould three linkage cylinder.This demolding mechanism could conduct the core pulling at the corner and let out the mold motion space,and then the three-linkage mechanism could realize a synchronous linkage to internal contraction type three-slide block core pulling mechanism.The results indicated that the mechanism had a simple and practical structure.关键词
