扣盖内滑块四侧抽芯注射模设计

Design of injection mould with inner sliding block core-pulling in four directions for fastener cover

针对塑件试制阶段模具的一些缺陷,设计了内滑块四侧抽芯注射模,并介绍了与四侧抽芯相关的模具零件设计。与原模具相比,内滑块四侧抽芯注射模制作难度与制作成本显著降低。

An injection mould with inner sliding block core-pulling in four directions was developed to replace the original one, which was found some defects during the trial production process. The design of mould parts was presented. The difficulties and costs in manufacturing the injection mould with inner sliding block core-pulling in four directions were reduced markedly compared with that of the primary one.
