Description

涂胶共挤模具
技术领域
本发明涉及塑料生产技术领域，具体地说是涉及生产塑料型材的模具。
背景技术
塑料型材的共挤模具包括模具本体，模具本体具有模腔，模具本体具有前面的进口和后面的出口，进口和出口之间就是模腔，所述的模具侧面还有第二进口通向模腔，所述的模腔在第二进口的交接处后面具有变大的结构，现有技术中，模具本体后面没有涂胶装置，常常出现第一次进入的中心材料和从第二进口处进入的的材料（外面的表层材料）脱层的现象，影响产品的质量。
发明内容
本发明的目的就是针对上述缺点，提供一种减少脱层现象、第一次进入的中心材料和外面的材料结合得更好、提高产品质量的涂胶共挤模具。
本发明的技术方案是这样实现的：涂胶共挤模具，包括模具本体，模具本体具有前面的进口和后面的出口，进口和出口之间是模腔，所述的模具侧面还有第二进口通向模腔，所述的模腔在第二进口的交接处后面具有变大的结构，其特征是：所述的模腔在第二进口的交接处前面具有一圈环绕模腔壁上的凹槽，凹槽连通模具本体外面具有进胶通道。
进一步地讲，所述的凹槽内设置有蓄胶垫，所述的蓄胶垫内部是空芯的、外面是海绵、泡沫或布料结构。
本发明的有益效果是：这样的涂胶共挤模具具有减少脱层现象、第一次进入的中心材料和外面的的材料结合得更好、提高产品质量的优点；所述的凹槽内设置有蓄胶垫，所述的蓄胶垫内部是空芯的、外面是海绵、泡沫或布料结构，具有涂胶更均匀、减少浪费的优点。
附图说明
图1是本发明的纵剖面结构示意图。
其中：1、模具本体   2、进口   3、出口   4、第二进口   5、变大的结构   6、凹槽   7、蓄胶垫   8、模腔   9、进胶通道。
具体实施方式
下面结合附图对本发明作进一步说明。
如图1所示，涂胶共挤模具，包括模具本体1，模具本体具有前面的进口2和后面的出口3，进口2和出口3之间是模腔8，所述的模具侧面还有第二进口4通向模腔8，所述的模腔在第二进口的交接处后面具有变大的结构5，其特征是：所述的模腔在第二进口的交接处前面具有一圈环绕模腔壁上的凹槽6，凹槽连通模具本体外面具有进胶通道9。
使用时，进胶通道连接进胶管，这样就可以在两次进入的原料形成的产品之间涂抹上一层胶，这层胶对其进行粘接，具有本发明的优点。
进一步地讲，所述的凹槽内设置有蓄胶垫7，所述的蓄胶垫7内部是空芯的、外面是海绵、泡沫或布料结构。这样蓄胶垫起着涂抹的作用，并且涂抹均匀，就像刷子一样，具有效果更佳的优点。
以上所述仅为本发明的具体实施例，但本发明的结构特征并不限于此，任何本领域的技术人员在本发明的领域内，所作的变化或修饰皆涵盖在本发明的专利范围内。
