Description

一个型腔内多个浇注口的料道结构
技术领域
本发明涉及产品模具的结构技术领域，具体为一个型腔内多个浇注口的料道结构。
背景技术                                                         
现有模具在浇注产品时，一个型腔一般只对应一个浇注口，对于面积较大的板材产品，一个浇注口需要向各个方向流动液体，使得浇注的时间长，由于浇注时间长，使得近浇注口端、远浇注口端的料液的凝结时间相差很大，使得产品浇注成型后，其各部分的孔隙率等不一致，进而会使得产品的外观收到影响。
发明内容
本发明提供了一个型腔内多个浇注口的料道结构，其使得面积较大的板材产品在浇注成型过程中所需要的浇注时间短，且产品的各部分的孔隙率等基本一致，确保了产品的外观。
一个型腔内多个浇注口的料道结构，其技术方案是这样的：其包括前模、后模、浇口板、浇口套、A板、B板，所述前模、后模之间为型腔，所述型腔内为面积较大的板材产品，所述浇口套位于所述浇口板内部，其特征在于：所述浇口套的底部中心下方设置有聚集料腔，所述聚集料腔位于所述浇口板和所述A板之间，所述聚集料腔向外设置有八条以其为原点的放射形水平料道，所述浇口套内的入料流道的下端部连通所述聚集料腔，每条所述水平料道的终点连接有对应的垂直料道，所述垂直料道连通所述型腔的浇注点。
采用本发明的结构后，由于入料流道分成八条分流道分别浇注到型腔的八个浇注点，其使得面积较大的板材产品在浇注成型过程中所需要的浇注时间短，且产品的各部分的孔隙率等基本一致，确保了产品的外观。
附图说明
图1为本发明的主视图结构示意图；
图2是图1的俯视图结构示意图。
具体实施方式
见图1、图2，其包括前模1、后模2、浇口板3、浇口套4、A板5、B板6，前模1、后模2之间为型腔7，型腔7内为面积较大的板材产品，浇口套4位于浇口板3内部，浇口套4的底部中心下方设置有聚集料腔8，聚集料腔8位于浇口板3和A板5之间，聚集料腔8向外设置有八条以其为原点的放射形水平料道9，浇口套4内的入料流道10的下端部连通聚集料腔8，每条水平料道9的终点连接有对应的垂直料道11，垂直料道11连通型腔的浇注点12。
