<p>PROBLEM TO BE SOLVED: To provide a production device for a molded part by injection molding provided with a stack mold capable of suppressing the generation of carbonized rubbish and resin leakage and performing molding at high precision.SOLUTION: Provided is a production device including: a movable platen operation mechanism 23 of controlling the moving speed of a movable platen 9 and moving the movable platen; and another driving source 24 supporting an intermediate die 5 from a direction confronted with a plasticization apparatus 1. Upon die opening, the movable platen is moved along a guide 26 to a die opening direction at a velocity higher than the speed at which the plasticization apparatus is moved by the movable platen operation mechanism, thus the die set of the movable platen is moved to the die opening direction, while allowing the intermediate die to receive the force at which the plasticization apparatus moves via a hot runner projection part 25, the another driving source is controlled so as to be moved to the die opening direction at the velocity same as that the plasticization apparatus moves, and the intermediate die is moved by the another driving source while being supported from the direction confronted with the plasticization apparatus.</p> |
