带有避位的模具

Mold with avoidance part

Abstract

本发明公开了一种带有避位的模具,包括上、下顶针板和顶针,所述顶针包括中部顶针和一侧顶针,所述中部顶针穿过所述上、下顶针板且顶端顶在胶口上,所述一侧顶针顶在模具的母模仁上,所述上、下顶针板之间开有一个凹槽,所述中部顶针的底端的厚度小于所述凹槽的高度,所述凹槽形成一个缓冲所述中部顶针的避位。本发明提供的带有避位的模具在上、下顶针板之间设有一个凹槽,使一侧顶针在顶出时料头先不动,当产品与胶口分离后中部顶针再进行顶出,这样胶口不会被顶断,提高生产效率和产品质量,降低生产成本。
The invention discloses a mold with an avoidance part. The mold with the avoidance part comprises an upper ejector pin plate, a lower ejector pin and ejector pins; the ejector pins comprise a middle ejector pin and a side ejector pin; the middle ejector pin penetrates through the upper ejector pin plate and the lower ejector pin plate, and the top of the middle ejector pin butts against a glue port; the side ejector pin butts against a female mold core of the mold; a groove is formed between the upper ejector pin plate and the lower ejector pin plate; the thickness of the bottom end of the middle ejector pin is less than the height of the groove; and the groove forms the avoidance part for buffering the middle ejector pin. According to the mold with the avoidance part, provided by the invention, the groove is formed between the upper ejector pin plate and the lower ejector pin plate, so that a stub bar does not move firstly when the side ejector pin is ejected out, and when a product is separated from the glue port, the middle ejector pin is ejected out again, so that the glue port can not be ejected to be fractured; and the production efficiency and the product quality are improved, and the production cost is lowered.
