INJECTION MOLDING MACHINE AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide an injection molding machine in which measure having high precision, control of filling and injection and management are enabled and application to existing structure is easily enabled and practical use is excellent. SOLUTION: The injection molding machine is constituted so that injection stroke or injection speed of an injection driver 2 can be controlled by a cylinder device 5 for injection driving which extrudes the injection driver 2 forward and controls it. A cylinder device 6 for controlling pressure in which a rod 6A for regulating pressure is provided so as to be freely advanced or retreated and moved in a runner part 10 of a sprue part 10A and a runner part 10B or the like in the inside of a mold 4. Resin pressure or injection pressure can be controlled to prescribed amount by advance or retreat and movement of the rod 6A for regulating pressure of the cylinder device 6 for controlling pressure.
