摘要:
An object is formed on a component with a positive flash shut-off during insert molding operations. The mold has a base with a cavity and a port that delivers a liquid to the cavity. The base has a component support structure for supporting the component and pockets formed on opposite sides of the cavity. The pockets are slightly spaced apart from the cavity by thin partitions. Inserts located in the pockets and are formed from a polymer. Both the partitions and inserts comprise the component support structure. The inserts have a dimension that is smaller than that of the base and partitions so as to form a compression fit around the component to reduce or eliminate flash down the component during the molding process.
摘要(中):
在插入成型操作期间,在具有正闪光切断的部件上形成物体。 模具具有一个具有空腔和一个将液体输送到空腔的端口的底座。 基座具有用于支撑形成在腔的相对侧上的部件和凹部的部件支撑结构。 口袋通过细分隔与空腔稍微间隔开。 位于袋中的插入件由聚合物形成。 分隔件和插入件都包括部件支撑结构。 插入件的尺寸小于基座和隔板的尺寸,以在组件周围形成压缩配合,以在模制过程中减少或消除组件的闪蒸。
