Title:
INJECTION APPARATUS AND MOLDING MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/259972
Kind Code:
A1
Abstract:
An injection apparatus 9 comprises an injection cylinder 27, a liquid-pressure device 43, a second electric motor 31B, and a control device 5. The injection cylinder 27 is coupled to a plunger 21 that extrudes a molding material M into a mold 101. The injection cylinder 27 also has a booster piston 41 that can be moved forward and backward. The liquid pressure device 43 supplies a hydraulic liquid to the injection cylinder 27. The second electric motor 31B is coupled to the booster piston 41. The control device 5 performs control on the liquid-pressure device 43 and the second electric motor 31B so as to simultaneously impart, to the booster piston 41, a first force, which is generated by the hydraulic liquid and which acts forward, and a second force, which is generated by the second electric motor 31B and which acts backward, and thereby cause the booster piston 41 to move forward.
