大弯度管件模具滑动抽芯锁模机构
本技术涉及一种大弯度管件模具滑动抽芯锁模机构,属于注塑模具领域。
技术介绍
采用注塑模具生产塑料管件,例如大弯度或90°管件,由于弯管存在转角,所以只能在弯头的两头分别进行抽芯,已有技术弯头抽芯大多采用整体摆动的抽芯方式,即将转角处的弯头整体摆动连接在其中一个芯子上,抽芯时,先将芯子直接抽出一部分,再通过摆动杆连接,使转角处的弯头镶块产生摆动,将弯头镶块从转角处脱出,再继续至抽芯完成,而另一个的芯子直接抽出。其缺点是:一方面,弯头镶块在摆动时容易发生碰撞损坏,正常需要停机维修、更换,增加维修成本;另一方面,由于是摆动连接,弯头镶块在复位时容易发生卡位现象,造成模具卡机,又影响生产效率。
