Title:
HYDRAULIC PRESSURE GENERATION DEVICE FOR INJECTION MOLDING MACHINE
Document Type and Number:
Japanese Patent JP3436345
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a more effective heat countermeasure technique of a hydraulic pressure generating device.
SOLUTION: Heat of an electric motor flows to a motor housing 33 as shown by arrows (1), (1) and then the same reaches a refrigerant passage 25 through both the front flange 32 and a collar 31 as shown by arrows (2), (2) and is absorbed by a refrigerant. Thereby, heat generation of the motor is absorbed by the refrigerant through a bracket and discharged outside of an injection molding machine. Accordingly, even if a hydraulic generation device is arranged in the inside of the bed of the molding machine in bad conditions, the electric motor is efficiently cooled.
