Description

便于加工的模内贴膜模具
技术领域
本发明涉及一种便于加工的模内贴膜模具，属于注塑模具领域。
背景技术
模内装饰技术（IMD）是目前国际风行的表面装饰技术，表面硬化透明薄膜，中间印刷图案层，背面注塑层，油墨中间，可使产品防止表面被刮花和耐摩擦，并可长期保持颜色的鲜明不易褪色。它是在薄膜表面上施以印刷、高压成型，再放入注塑模具中使其与注塑材料一体成型。但在实际注塑过程中，装饰薄膜放入型腔后，往往由于薄膜不能紧贴在型腔中，或注塑时流体冲击的影响，使薄膜发生褶皱移位等情况，影响贴膜装饰的效果。
发明内容
本发明所要解决的技术问题是提供一种便于加工的模内贴膜模具，对装饰薄膜的固定效果好，工序简单方便，并且能够自动清除注塑后残留的废料。
为解决以上技术问题，本发明采用的技术方案是：一种便于加工的模内贴膜模具，包括上方的定模和下方的动模，所述动模包括动模板和安装板，所述动模板和安装板通过立柱相连，所述安装板上设置有顶板，所述动模板上表面具有可供装饰薄膜放入的大凹槽，所述大凹槽周围与若干供装饰薄膜延长边放入的小凹槽相连，所述定模和动模闭合后中间形成型腔，所述型腔的周围形成若干与型腔相连的压膜腔，所述压膜腔的高度与装饰薄膜的厚度相等，所述动模板上设置有切刀通道，所述切刀通道内安装有切刀，所述切刀通道与压膜腔相连，所述切刀通过连杆与顶板相连，所述动模板上表面内嵌有滑块，所述滑块可从动模板外缘沿水平方向向压膜腔内滑动，所述滑块与电机相连，所述大凹槽的底面设置有若干抽气孔，所述抽气孔与真空泵相连。
所述小凹槽数量为两个，分别位于大凹槽的两侧。
所述动模上还设置有顶针，所述顶针可通过动模板上的顶针孔伸入型腔。
所述定模上设置有若干气孔。
所述定模上设置有注塑流道。
所述定模内安装有加热装置。
所述定模内安装有水冷降温管路。
本发明的有益效果在于：
动模板表面的大凹槽和小凹槽，在动模和定模闭合前对放入的装饰薄膜起定位作用，大凹槽底面的抽气孔与真空泵相连，可利用真空吸力使装饰薄膜紧贴在大凹槽内，使其在合模过程中不易移位，合模后形成的压膜腔，可利用定模和动模将装饰薄膜的延长边压紧，使其在注塑过程中不易移位；
注塑工序完成后，顶板将切刀顶起，切刀的刀头通过切刀通道进入压膜腔内，将装饰薄膜的延长边切从注塑产品上切去，产品注塑完成后不需要人工进行二次切边，使工序简单、方便；
动模板上设置的滑块，可在注塑工艺完成，并将注塑产品取出后，将切割下来的装饰薄膜废料或注塑残留从压膜腔内刮起推出，从而便于移除，使其防止废料残留在压膜腔内，影响下次注塑。
因此，本发明所提供的一种便于加工的模内贴膜模具，能牢固固定装饰薄膜，使其在合模、注塑过程中不易移位，还能自动切除多余的装饰薄膜，并自动清除注塑后残留的废料，贴膜效果稳定，工序简单方便。
