Description

树脂排咪模具
技术领域
本发明涉及一种模具，用于拉链生产，具体为树脂排咪模具。
背景技术
树脂拉链由链牙、拉头、限位码或锁紧件等组成。其中，链牙又被称之为咪牙，树脂拉链通过排牙模具注塑进行生产。
现有的树脂拉链咪牙注塑模具包括上模和下模，上模和下模各设有对应的半个咪牙型腔，包围形成用于注塑拉链咪牙的型腔。在该下模中央上方设有T形顶板，在合模时由下模底部设置的打板上的若干顶出销向上顶出使得该T形成形板可向上顶，并利用弹簧力量回复，使该T形成形板上下地往返动作，以此帮助产品脱模。上述构造中该T形成形板是至少三百多丝米以上的细长形体，受制于咪牙厚度，T形板上部两侧厚度都较薄，最小能达到10丝米。
这样在实际动作时往往会产生如下的缺点：上下往复动作的细长T形成形板经常与上、下模的咪牙型腔两侧边缘发生撞击而伤及注塑模上、下模的咪牙型腔两侧边缘和T形成形板。而T形成形板上部两侧厚度比较薄，因此经常被压坏。一方面经常更换T形成形板增加了模具的使用成本，另一方面也提高了模具的维修率。
发明内容
针对上述技术问题，本发明提供了一种树脂拉链排牙模具，以降低排牙模具的使用成本和维修率。
具体技术方案为：
树脂排咪模具，包括上模、下模和打板，下模有下咪牙型腔，下咪牙型腔两侧有下布带槽；对应的上模设有上咪牙型腔，上咪牙型腔两侧分别有上布带槽；上模还设置有主流道和多个分流道，主流道位于上咪牙型腔中间，分流道位于主流道两侧，分流道另一侧与对应的上咪牙型腔相连；下模下咪牙型腔中心线上有通孔，打板上对应有顶杆，顶杆安装在通孔内，顶杆的高度与通孔的深度相等；顶杆下降时，通孔内形成圆柱型腔。
本发明提供的树脂排咪模具，简化了树脂排咪模具结构，用顶杆脱模代替了以前顶板脱模的方式，一方面降低了排咪模具的制造难度，另一方面也降低了排咪模具的使用成本，提高了生产效率。
附图说明
图1是本发明的立体结构示意图；
图2是本发明的上模结构示意图；
图3是本发明的上模剖面结构示意图。
具体实施方式
结合附图说明本发明具体实施方式。
如图1、图2和图3所示，树脂排咪模具，包括上模1、下模2和打板3，下模2有下咪牙型腔5，下咪牙型腔5两侧有下布带槽11；对应的上模1设有上咪牙型腔4，上咪牙型腔4两侧分别有上布带槽；上模1还设置有主流道12和多个分流道13，主流道12位于上咪牙型腔4中间，分流道13位于主流道12两侧，分流道13另一侧与对应的上咪牙型腔4相连；下模2下咪牙型腔5中心线上有通孔10，打板3上对应有顶杆9，顶杆9安装在通孔10内，顶杆9的高度与通孔10的深度相等；顶杆9下降时，通孔10内形成圆柱型腔14。
注塑机将拉链的两根布带分别沿着下布带槽11，两根布带分别落入对应的咪牙型腔5中,同时打板3向下沉，顶杆9与下模2的通孔10围成若干个圆柱型腔14。合模后，树脂料沿着主流道12流入圆柱型腔14和分流道13，经分流道13流入相应的上咪牙型腔4和下咪牙型腔5组成的型腔内，进行咪牙的制作，流入圆柱型腔14形成圆柱，咪牙制作完毕，分模，打板3上顶杆9向上顶料，顶杆9顶起圆柱脱模，注塑机将布带进一个模具的距离后继续进行上述制作步骤，如此重复，就实现了树脂拉链的排咪。
