INJECTION MOLDING MACHINE FOR THERMOPLASTIC RESIN

摘要

PROBLEM TO BE SOLVED: To provide an injection molding machine for a thermoplastic resin capable of being miniaturized by enabling simple and highly accurate injection molding to be carried out by eliminating a weighing process. SOLUTION: An injection molding machine is provided with a plasticizing device B for plasticizing a thermoplastic resin and the injection device A connected to the plasticizing device B through a connection passage 3 to inject the plasticized resin in a mold. The rotary pump 4 of which the suction port is connected to the plasticizing device B and the emitting port is connected to the mold is provided to the plasticizing device A and the plasticized resin is intermittently injected in the cavity of the mold by the rotary pump 4. An accumulator device C storing one injection amt. or more of the resin plasticized in the plasticizing device B and sending out the same to the rotary pump 4 is provided to the connection passage 3.
