发明名称 Injection molding method using a fixed die and a movable die
摘要 A die for injection molding in which a molded product is supported by a core for a certain time in a cavity block even after an opening operation of the die is started, and the molded product is taken out of the die after the molded product is solidified so that the molded product is not deformed at a mold-releasing time and a stable molded product can be obtained with high productivity. A projecting mechanism has a separating delay device for pressing the molded product by the core and supporting the molded product in the cavity block until a movable side die is separated by a predetermined distance from a fixed side die. The separating delay device releases the supporting of the molded product after the movable side die is separated by the predetermined distance from the fixed side die.
