とするトランスフア成形用金型。 When the mold is closed, the molding material in the pot part is injected into the cavity formed by the fixed mold and the movable mold through the sprue communicating with the pot part and the gate formed in the fixed mold by the pressing operation of the plunger. In the transfer molding mold for performing molding, the flow path area of the sprue opening is narrowed at a portion of the pressing surface of the plunger opposite to the sprue opening opening to the pot portion when the plunger pressing operation is completed. A mold for transfer molding characterized by having a convex portion formed therein.
