Abstract
An injection molding machine for molding with a high polymer material such as rubber and resin which is improved in the working efficiency and productivity thereof. The injection molding machine comprises a plurality of independent metallic molds, a metallic mold securing device having two receiving portions for receiving and clamping the metallic molds therein, a metallic mold loading and unloading device for loading and unloading the metallic molds to and from the receiving portions, and a drive device for moving the metallic mold securing device. Accordingly, injection and vulcanization can be carried out alternately for two metallic molds so that, also during vulcanization for the first metallic mold, injection to the cavity of the second metallic mold can be carried out. The metallic mold securing device can otherwise have more than two such receiving portions when necessary.
