Description

一种便于圆筒状TPU橡胶产品脱模的注塑成型模具
技术领域
本发明涉及一种便于圆筒状TPU橡胶产品脱模的注塑成型模具。
背景技术
注塑模具是一种生产塑胶制品的工具，也是赋予塑胶制品完整结构和精确尺寸的工具。注塑成型是批量生产某些形状复杂部件时用到的一种加工方法，具体指将受热融化的塑料由注塑机高压射入模腔，经冷却固化后，得到成形品。
有些注塑产品脱模比较困难，如圆筒状TPU橡胶产品，一般模具设计产品脱模采用顶出或一般的结构拉出方式，但因TPU橡胶材料特性，产品质地软，且产品表面光滑，与模具表面粘附力大。常规的顶出或拉出方式会造成产品损伤或产品无法脱模（产品会粘附在母模侧）。
发明内容
本发明的目的在于提供一种便于圆筒状TPU橡胶产品脱模的注塑成型模具，脱模时，公模仁入子能将产品从母模仁入子中拉出，产品可顺利脱模。
为实现上述目的，本发明的技术方案是设计一种便于圆筒状TPU橡胶产品脱模的注塑成型模具，包括由上至下依次设置的：面板、A板、母模仁、推板、公模仁、B板、顶针板和底板；
所述面板的上端面和底板的下端面均固接有隔热板；
所述公模仁内嵌有竖置圆柱形公模仁入子；
所述母模仁内嵌有带竖置中空圆柱形内腔的母模仁入子；
所述公模仁入子贯穿推板并插入母模仁入子的内腔中，组成用于成型圆筒状橡胶产品的成型腔；
所述公模仁入子顶部设有环形倒扣，所述公模仁入子在其外周壁的竖向中部设有外螺纹。
优选的，所述顶针板上设有回针，所述回针外周套装有弹簧。
优选的，所述B板和底板间还设有垫块。
优选的，所述成型腔共有六个。
本发明的优点和有益效果在于：提供一种便于圆筒状TPU橡胶产品脱模的注塑成型模具，脱模时，公模仁入子能将产品从母模仁入子中拉出，产品可顺利脱模。
公模仁入子顶部设有环形倒扣（导向倒扣结构），且公模仁入子在其外周壁的竖向中部设有外螺纹（螺纹状突起结构），脱模时，公模仁入子能从产品的顶端和中部同步施加脱模方向的力，将产品从母模仁入子中拉出，推板再将产品从公模仁入子上顶出，产品可顺利脱模。
附图说明
图1是本发明的示意图。
具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步描述。以下实施例仅用于更加清楚地说明本发明的技术方案，而不能以此来限制本发明的保护范围。
本发明具体实施的技术方案是：
如图1所示，一种便于圆筒状TPU橡胶产品脱模的注塑成型模具，包括由上至下依次设置的：面板1、A板2、母模仁3、推板4、公模仁5、B板6、顶针板7和底板8；
所述面板1的上端面固接有隔热板11；
所述底板8的下端面固接有隔热板81；
所述公模仁5内嵌有竖置圆柱形公模仁入子9；
所述母模仁3内嵌有带竖置中空圆柱形内腔的母模仁入子（图中未示出）；
所述公模仁入子9贯穿推板4并插入母模仁入子的内腔中，组成用于成型圆筒状橡胶产品的成型腔；
所述公模仁入子9顶部设有环形倒扣91，所述公模仁入子9在其外周壁的竖向中部设有外螺纹92。
所述顶针板7上设有回针71，所述回针71外周套装有弹簧。
所述B板6和底板8间还设有垫块（图中未示出）。
所述成型腔共有六个。
公模仁入子9顶部设有环形倒扣91（导向倒扣结构），且公模仁入子9在其外周壁的竖向中部设有外螺纹92（螺纹状突起结构），脱模时，公模仁入子9能从产品的顶端和中部同步施加脱模方向的力，将产品从母模仁入子中拉出，推板4再将产品从公模仁入子9上顶出，产品可顺利脱模。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
