The utility model relates to an injection mold for the sole of a shoe, which consists of a front die and a rear mold with each other. The inner cavity of the rear mold is inserted. The upper end of the insert is arranged with a front die. The upper end of the material head is fixed with a needle valve and a top needle. The upper end of the front die is connected with a stripper plate, the upper end of the stripper plate is connected with a cover plate, and the middle of the cover plate is opened in the middle. A feeding port is provided with a feeding mouth running through the cover plate and extending to the front die, the lower end of the rear die is connected with the cushion plate, the bottom of the cushion plate is connected with the bottom plate, a sinking head is opened on the cover plate, a locking screw is arranged in the head hole, and the locking screw runs through the cover plate and the stripper plate and extends to the front die, and the front die is provided with a screw hole with locking screws. The utility model is provided with a screw hole with a locking screw. The utility model is provided with a screw hole with locking screws. By setting the needle valve at the lower end of the feeder, the new method of small point injection is realized and the traditional way of glue is replaced. After the injection is completed, the needle valve is pulled out from the molding product at the opening of the mold, but it will not leave the gate mark on the surface of the product, reduce the waste of the material, and save the process of artificial cutting.
【技术实现步骤摘要】
一种鞋底的注塑模具
本技术涉及注塑模具领域,尤其涉及一种鞋底的注塑模具。
技术介绍
鞋底在生产过程中通常需要先将材料倒入注塑模具中,得到一个简单的成型鞋模,后期再对该鞋模进行加工,即可得到成品鞋底,其中的鞋底注塑模具是一种根据鞋底的形状和大小自动将鞋注塑成型的机器,传统的注塑模具大多采用点胶口方式,此种方式的进胶口会在产品表面留下一个浇口痕,浇口痕的大小取决于不同的塑料,往往还需要人工去剪除,不仅费时费力,而且在剪除过程中容易对产品造成伤害,这就需要设计一种不留浇口的鞋底注塑模具。
技术实现思路
本技术的目的是提供一种鞋底的注塑模具,通过在料头下端设置针阀,实现小点进胶方式,替代了传统的点胶口方式,注塑完成后,在开模时将针阀从成型产品中拔出,而不会在产品表面留下浇口痕,减少了材料的浪费,而且省去了人工剪除的工序。为了实现以上目的,本技术采用的技术方案为:一种鞋底的注塑模具,它包括相互配合的前模和后模,所述的后模内腔放置镶件,所述的镶件上方设置有贯穿前模的料头,所述的料头下端固连针阀、上端配合顶针,所述的前模上端连接脱料板,所述的脱料板上端连接盖板,所述的盖板中部开设有进料 ...
