The utility model puts forward a nozzle hook needle with push plate for soft rubber mould, which relates to the technical field of plastic mould, including fixed formwork, push plate, bottom plate of ejector needle and ejector needle panel. The upper end of the fixed formwork is provided with a die-ren structure, which includes a front die and a rear die, a nozzle hook needle is arranged at the top of the ejector needle bottom plate, and the upper end of the nozzle hook needle passes through the ejector panel, push plate, fixed formwork and rear die, and the nozzle hook needle is located The part inside the template is provided with a meson, a spring is arranged on the meson, and the spring is sleeved on the nozzle hook needle. The front die is provided with a rubber feeding channel. The top of the nozzle hook needle is inverted and extended into the rubber feeding channel, and a space for avoiding collision is provided on the ejector pin panel. The nozzle hook needle of the utility model will not retreat along with the push plate or remain relatively stationary because it is avoided for a period of travel in the ejector pin panel, so that the nozzle can be broken only when the reverse buckling of the nozzle hook needle is opened in the front and rear dies. It not only meets the requirements of opening moulds for such products as soft plastics, but also has simple structure, easy fabrication, short manufacturing cycle and stable movement.
【技术实现步骤摘要】
一种带推板的软胶模水口勾针
本技术涉及塑胶模具
,尤其是一种带推板的软胶模水口勾针。
技术介绍
随着经济不断发展及社会不断进步,提供了丰富的物质消费品,为提高人们的生活水平及追求个性化的生活创造良好的条件,从而加速了物质消费品的需求量,而塑胶制品就是诸多物质消费品的一种。为了提高舒适触感,很多消费产品用软塑胶制成。而塑料的特性质软不受力,托模困难,一般不能在接触面下顶针,由于不受力容易顶高。大多用水口辅助顶出,软塑料的收缩性及延展性良好,经常在射嘴与模具入水口不能分离,拉胶丝。特别是带推板的模具水口都无法拉断,导致无法生产。
技术实现思路
本技术的目的是克服现有技术存在的缺陷,提供一种带推板的软胶模水口勾针,结构简单、易于制作、动作稳定。本技术具体采用如下技术方案实现:一种带推板的软胶模水口勾针,包括定模板、推板、顶针底板及顶针面板,所述定模板上端设有模仁结构,所述模仁结构包括前模及后模,所述顶针底板上端设有水口钩针,所述水口钩针上端穿过所述顶针面板、推板、定模板及所述后模,所述水口钩针位于所述定模板内的部位设有介子,所述介子上设有弹簧,所述弹簧套设在所述水口钩针上 ...
【技术保护点】
1.一种带推板的软胶模水口勾针,其特征在于,包括定模板、推板、顶针底板及顶针面板,所述定模板上端设有模仁结构,所述模仁结构包括前模及后模,所述顶针底板上端设有水口钩针,所述水口钩针上端穿过所述顶针面板、推板、定模板及所述后模,所述水口钩针位于所述定模板内的部位设有介子,所述介子上设有弹簧,所述弹簧套设在所述水口钩针上,所述前模设有进胶流道,所述水口钩针顶部的倒扣伸入所述进胶流道,所述顶针面板上开设有避让空间。
