PURPOSE:To omit a finishing process by which a molded product is separated from a runner system, by providing a constitution wherein a gate is formed in an arcuate shape, and the tip of said gate is communicated to a cavity at the surface of a metal mold along its parting line. CONSTITUTION:In a removing process, an ejector pin 14 is moved in the reverse direction of an arrox X in order to remove the molded product E, a runner part F, and a gate part G which remain in a fixed mold 8 after a mold opening process. The tip of the gate part G is separated by the movement from the molded product E. The gate part G is elastically deformed and pulled out of the gate 13. Finally the molded product E and the runner system are removed from the fixed mold 8 in the separated state from each other. |
