Abstract

PURPOSE:To increase stability in time of molding and mold a thick walled article with high efficiency, by providing the mold stopping unit having compressing tie bars to the mold of an injection molding machine and giving beforehand the predetermined clamping force to the mold. CONSTITUTION:The tie bar 19 of the mold stopping unit 15 is extended by the pulling mechanism 24 and the empty mold 16 is inserted. When the pulling force of the pulling mechanism 24 is released, the tie bar 19 contracts and compresses the mold 16. This is transferred and fixed between the mold attaching platens 2, 3. After injection molding is done, the mold stopping unit 15 is taken off, the mold being clamped, the tie bar is again extended by the pulling mechanism 24, the mold 16 is taken out and the molded article is take out by opening the mold.
