Abstract
PURPOSE: To provide an injection and extrusion molding apparatus employing an injecting apparatus which intermittently injects and extrudes sheets together with a rotating drum in a molding machine, for performing extrusion and molding on the same line, reducing the trimming loss portion and improving yield.
CONSTITUTION: An injecting apparatus 2 intermittently injects plasticized resin and a die 3 extrudes sheets M at unit lengths. In synchronization with the injection and extrusion speeds, a steel belt type sheet moving apparatus 8 and a clip type sheet moving apparatus 10 move the sheet M to a molding machine 9, with the sheet (m) ends clipped. Being regulated to a molding temperature in a temperature regulating unit 11, the sheet M is wound on the upper half circumferential surface of a rotating drum 12 by a 180° rotation of the drum 12. By lowering an upper mold 15, molded product portions (m) and (n) corresponding to molding cores 17a and 17b are formed projecting. Then, clips 18 having clipped the upper half circumferential surface are simultaneously all opened to discharge the molded product portions (m) and (n), which are cut out into a given shape by a trimming press 23.
