Abstract

A molding machine disclosed herein comprises a rotary disk having the required number of openable and closeable neck molds, said rotary disk being located on the underside of a base plate, said rotary disk being capable of achieving intermittent rotation to successively transport said neck molds to an injection molding stage, a temperature control stage, a stretching blow molding stage and a molded product releasing stage for continuous operation from the injection molding of bottomed parisons formed of synthetic resin to the releasing of hollow molded products such as bottles subjected to the stretching and blow molding. In the present invention, arranged movably up and down on the base plate is a single actuating plate extending over individual operating stages consisting of the temperature control stage, the stretching and blow molding stage and the releasing stage, and members required for the temperature control of the injection molded parisons, the stretching blowing and the releasing of the hollow molded products are mounted on three sides of the actuating plate whereby the function of the single actuating plate is made possible to simultaneously actuate three operating stages which consist of the temperature control stage, the stretching and blow molding stage and the releasing stage.
