Abstract

PURPOSE:To obtain a mold device capable of providing a long inside-mold cooling time even when using a general purpose molding machine by using a system in which a mold-camping force is received by the molding machine during the injection molding period and also given by a fluid type clamper during the mold-cooling period. CONSTITUTION:A mold unit 4 in which a mold 26 is set is set between a fixed mold fitting plate 5 and a movable mold-fitting plate 6 in a general purpose molding machine. During the injection molding period, a necessary strong mold- clamping force is given by the mold-clamping mechanism of the general purpose molding machine. After the injection molding, compressed air is set through a primary solidifying process to an air chamber 28, and under the condition that the mold 26 is pressed by a pushing plate 29, the mold unit 4 is removed from the general purpose molding machine.
