Description
技术领域
本发明涉及一种模内贴膜模具,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模内贴膜模具,贴膜效果稳定,工序简单方便。
为解决以上技术问题,本发明采用的技术方案是:一种模内贴膜模具,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,使其不易移位,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。
因此,本发明所提供的一种模内贴膜模具,利用模具本身固定装饰薄膜,使其不易移位,并能自动切除多余的装饰薄膜,贴膜效果稳定,工序简单方便。
