INJECTION MOLDING MACHINE SHIELDING MOLD CLAMPING HEAT INSULATING PORTION, REGION INCLUDING STATIONARY PLATEN AND MOVABLE MOLD, WITH HEAT INSULATING STRUCTURE MEMBER

摘要

PROBLEM TO BE SOLVED: To provide an injection molding machine that suppresses a temperature rise around the molding machine by preventing discharge heat generated from a mold clamping mechanism portion of the injection molding machine from being released to outside air and enables increase of energy efficiency.SOLUTION: A mold clamping mechanism portion and a mold 4 are shielded by a heat-insulating cover 5 and heat discharged from a servo motor for mold clamping and the mold 4 can be confined in the heat-insulating cover 5 by the heat-insulating cover 5. The heat-insulating cover 5 is composed of a partition 6 and a heat insulating material 7, and by close contact of a refrigerant 8 and by providing a refrigerant transport device 9 and pumping the refrigerant 8 to a flow passage 10 for refrigerant, heat released from the mold clamping mechanism portion and the mold 4 is discharged via the refrigerant 8 instead of directly releasing to outside air in a factory in which the injection molding machine is installed.
