Description

二次顶出模具Second ejection mold

技术领域 technical field

 本实用新型涉及模具技术领域,具体涉及一种二次顶出模具。 The utility model relates to the technical field of molds, in particular to a secondary ejection mold.

背景技术 Background technique

模具是注塑成型中不可缺少的重要装备。注塑成型是将热熔状态的塑胶材料高速的注入到模具内具有所需形状的密闭成型空间中,等塑胶材料冷却固化后,打开模具将固化的塑胶加工物顶出,以获得成型品的方法。由于注塑成型方法具有成型费用低、成型周期短、成型过程简单及易于成型形状复杂的塑胶产品等特点,因此在塑胶产品制造领域应用极为普遍。 Mold is an indispensable and important equipment in injection molding. Injection molding is a method of injecting hot-melt plastic material into a closed molding space with the desired shape in the mold at high speed, and after the plastic material cools and solidifies, the mold is opened to eject the solidified plastic processed product to obtain a molded product. . Since the injection molding method has the characteristics of low molding cost, short molding cycle, simple molding process, and easy molding of plastic products with complex shapes, it is widely used in the field of plastic product manufacturing.

当从模具中待取出的成品的形状特殊,或者是根据量产时的要求,如果在一次顶出后,成品仍然在模穴中,或者是无法自动脱落时,就需要再增加一次顶出动作,这样的顶出动作即为二次顶出。二次顶出能够让顶出流程顺畅化,对于某些顶出行程需求较大的产品,利用二次顶出可以减少顶针在顶出时施加的力,避免顶出时造成产品的缺陷。然而现有的二次顶出模具虽然能大致满足使用要求,但设计都不算巧妙,其结构复杂,加工周期长,成本高,不易维护,且模具的整个运动不是很顺畅和平衡。 When the shape of the finished product to be taken out from the mold is special, or according to the requirements of mass production, if the finished product is still in the mold cavity after one ejection, or cannot fall off automatically, it is necessary to add another ejection action , such ejection action is the second ejection. Secondary ejection can make the ejection process smoother. For some products that require a large ejection stroke, the use of secondary ejection can reduce the force exerted by the ejector pin during ejection and avoid product defects during ejection. However, although the existing secondary ejection molds can roughly meet the requirements of use, the design is not ingenious, the structure is complicated, the processing cycle is long, the cost is high, and it is difficult to maintain, and the entire movement of the mold is not very smooth and balanced.
