Title:
MOLDING METHOD OF INJECTION MOLDING MACHINE
Document Type and Number:
WIPO Patent Application WO/2011/161899
Kind Code:
A1
Abstract:
When molding is performed by injecting and filling resin (R) at a predetermined injection pressure by an injection device into a die (2) configured from a fixed die (2c) and a movable die (2m) which are clamped by predetermined clamping force by a clamping device, a clamping device (Mc) which enables natural compression of the resin (R) accompanying the solidification of the resin (R) within at least the die (2) is used as the clamping device, mold injection pressure (Pi) and mold clamping force (Pc) at which a predetermined die clearance (Lm) is generated between the movable die (2m) and the fixed die (2c) at the time of injection and filling and a non-defective product can be molded are previously found and set, at the time of production, the clamping device (Mc) is clamped at the mold clamping force (Pc), the mold injection pressure (Pi) is set as limit pressure (Ps), the resin (R) is injected and filled into the die (2) by driving the injection device (Mi), and thereafter a molded product (G) is removed after a predetermined cooling time (Tc).
