Ejection device for a mold and injection molding machine using the same

摘要

A mold ejection device (25) includes a main body (251), at least one first ejection mechanism (252) and at least one second ejection mechanism (253). The main body includes one first receiving recess (2512) and one second receiving recess (2514) defined in two opposite surfaces of the main body, respectfully. The first ejection mechanism is assembled and received within the first receiving recess. The first ejection mechanism includes a first piston (2524) slidably assembled within the first receiving recess and a first ejector (2525) fixed to the first piston. A distal end of the first ejector faces toward and slidably passes through the first surface. The second ejection mechanism has substantially the same structure as the first ejection mechanism and is slidably assembled and received within the second receiving recess. An injection molding machine (200) using the mold ejection device is also provided.
