Abstract This invention relates to a molding machine for synthetic resin article, comprizing journals provided turnably and revolvably between upper and lower bearing boards, a central die plate whose both sides have been formed into mold fixing surfaces die plates which move forward and backward by mold tightening cylinders approachably to and releasably from each of said mold fixing surfaces of the central die plate, to guide rods mounted between the upper and lower positions of fixed boards provided on the base and said bearing boards and a suitable number of injection devices respectively onto the base at the positions outside the fixed boards in such a manner that the nozzles of said injection devices are capable of advancing and retreating to and from respective injection openings of the movable die plate.
A molding machine for synthetic resin article, comprizing journals provided turnably and revolvably between upper and lower bearing boards, a central die plate whose both sides have been formed into mold fixing surfaces, die plates which move forward and backward by mold tightening cylinders, approachably to and releasably from each of said mold fixing surfaces of the central die plate, to be guided with rods mounted between the upper and lower positions of fixed boards provided on the base and said bearing boards, and a suitable number of injection devices respectively onto the base at the positions outside the fixed boards in such a manner that the nozzles of said injection devices are capable of advancing and retreating to and from respective injection openings of the movable die plate.
