Abstract

本实用新型提供的一种长筒注塑件脱模装置，包括芯子、推板，推板设在芯子的外部，其特征在于：芯子本体中还设有进气通道，进气阀杆装置在进气通道中，进气阀的前端为进气阀，尾部套装有复位弹簧。在芯子上端加上进气阀结构，由弹簧拉动复位，熔融的塑胶充填到塑料模的型腔内，当冷却使塑料件成型后，推板推出塑料件，在推板推的过程中，产生的负压使进气阀打开，外界气体进入塑料件内，使塑料件的内外压力平衡，用于解决盲孔注塑件脱模时产生负压变形问题，从而保证了塑料件的质量。

Description

一种长筒注塑件脱模装置
技术领域
本实用新型提供一种长筒注塑件脱模装置，用于注塑长筒型塑料产品时能够顺利脱模装置，属于注塑成型技术领域。
背景技术
在塑料产品生产技术领域中，注塑盲孔长筒塑料件脱模时，芯子在脱离塑料件的过程中，会产生负压，在外界压力下能把塑料件压瘪，造成塑料件不良。
发明内容
本实用新型提供一种长筒注塑件脱模装置，解决了盲孔长筒塑料件在脱模过程中负压对塑料件的影响。
   本实用新型提供的一种长筒注塑件脱模装置，技术解决方案如下：包括芯子、推板，推板套装在芯子的外部，其特征在于：芯子本体中还设有进气通道，进气阀杆装置在进气通道中，进气阀的前端为进气阀，芯子的尾部套装有复位弹簧。
本实用新型的积极效果在于：在芯子上端加上进气阀结构，由弹簧拉动复位，熔融的塑胶充填到塑料模的型腔内，当冷却使塑料件成型后，推板推出塑料件，在推板推的过程中，产生的负压使进气阀打开，外界气体进入塑料件内，使塑料件的内外压力平衡，用于解决盲孔注塑件脱模时产生负压变形问题，从而保证了塑料件的质量。
附图说明
图1是本实用新型的装置图。
图中1、芯子；2、进气阀杆；3、进气阀；4、进气通道；5、复位弹簧；6、推板；7、工件。
具体实施方式
根据图1所示，本实用新型由芯子1、推板6构成，推板6套装在芯子1的外部，可相对移动，其特征在于：芯子1本体中还设有进气通道4，进气阀杆2装置在进气通道4中，进气阀2的前端为锥形的进气阀3，尾部套装有复位弹簧5。
本实用新型在注塑生产时，熔融的塑胶充填到模具型腔内形成塑料件7，冷却成型后由推板5在外力的推动下，推动塑料件7脱离芯子1，在推动过程中塑料件7和芯子1之间会产生负压，外界的气压会压迫进气阀3打开，外界气体通过进气阀3与芯子1之间的间隙进入负压空间，从此使塑料件7内外气压平衡，保证塑料件7的质量。
