Abstract

本发明公开了一种生产硅胶薄膜的模具，硅胶薄膜四周设置复数个进料口，硅胶薄膜中央设置排气销，所述排气销上端与硅胶薄膜的表面平齐，排气销上端与下端之间设置凹槽作为排气、溢料、易清除毛边的通道。利用本发明可以有效地减少硅胶薄膜生产跑料过程中气泡、砂孔、穿孔的产生。

Description

一种生产硅胶薄膜的模具
【技术领域】
本发明涉及模具，尤其涉及一种生产硅胶薄膜的模具。
【背景技术】
现有生产硅胶薄膜的模具在硅胶薄膜侧边开设进料口，从硅胶薄膜对称侧边设置排气孔。
使用这种结构的硅胶模具，当从硅胶薄膜侧边的进料口进料时，将导致进料不均衡，硅胶在外圈先跑满，而内圈会因较薄而跑料不饱，导致出现气泡、砂孔、穿孔现象。
【发明内容】
本发明针对现有技术的上述缺陷，提供一种生产硅胶薄膜的模具，以防止生产出的硅胶薄膜出现气泡、砂孔、穿孔。
为了解决上述技术问题，本发明是通过以下技术方案实现的：
一种生产硅胶薄膜的模具，硅胶薄膜四周设置复数个进料口，硅胶薄膜中央设置排气销，所述排气销上端与硅胶薄膜的表面平齐，排气销上端与下端之间设置凹槽作为排气、溢料、清除毛边的通道。
所述进料口为四个，均匀在分布在硅胶薄膜四周。
所述硅胶薄膜的平面中央设置顶针。
从以上技术方案可以看出，本发明在硅胶薄膜边缘四周设置复数个进料口，硅胶从进料口进入后将空气推挤到薄膜中央位置，空气再从硅胶薄膜中央位置的排气销凹槽排出，避免了空气遗留在模腔中形成气泡、砂孔或穿孔，有效地提高了产品的优品率。
【附图说明】
图1为本发明俯视图；
图2为本发明截面视图。
【具体实施方式】
下面结合附图与具体实施方式对本发明作进一步详细的说明介绍：
图1为本发明俯视图。参见图1所示，从图中可以看出，在硅胶薄膜模腔1四周开设四个进料口，其均匀分布在硅胶薄膜1的四周。
再参见图2所示，本发明包括硅胶薄膜模腔1以及设置在基模中央的排气销2。排气销2上端宽，排气销的下端比上端略小，排气销上端与硅胶薄膜表面平齐，上端与下端之间有凹槽设计，通过该凹槽将气体排出模腔。硅胶从硅胶薄膜模腔1上的四个进料口进入模腔，空气在硅胶的推挤下从四周挤压到中央，空气到中央后再从排气销中的凹槽排出。
作为本发明的优选实施例，在基模下面还设置顶针3，用于将排气销顶出。
以上所述仅为本发明的较佳实施例，凡跟本发明权利要求范围所做的均等变化与修饰，均应属于本发明权利要求的涵盖范围。
