Title:
INJECTION MOLDING MACHINE AND INJECTION FOAM MOLDING METHOD
Document Type and Number:
Japanese Patent JP2022138971
Kind Code:
A
Abstract:
To provide an injection molding machine and an injection foam molding method that efficiently expel residual gas in a mold cavity from a mold mating surface during injection filling of foamable molten resin.SOLUTION: An injection molding machine 10 includes: a mold clamping device 30 that performs a mold opening and closing operation to move a movable mold 34 closer to and farther from a fixed mold 33, and a mold clamping operation to form a mold cavity 38 by applying a mold clamping force to a fixed mold 36 and a movable mold 37 that are brought into contact; an injection device 20 that stores a foamable molten resin in a reservoir 21a in front of a screw 22 and injects and fills the mold cavity 38 with the foamable molten resin from the reservoir 21a; and a control device 40 that controls the mold clamping device 30 and the injection device 20. The control device 40 performs control to increase the mold clamping force based on position information of the screw 22 during injection filling.SELECTED DRAWING: Figure 3
