Abstract
A movable mold includes a main mold part, a separate mold part separate from the main mold part, and a relative movement mechanism moving the separate mold part relative to the main mold part in a driving direction of a mold driver.
Claims8
A resin molding device for molding a resin product including a resin base material that includes a foamed layer, the resin molding device comprising:
- a first mold;
- a second mold having a base material-molding surface serving to mold a surface of the base material opposite to the first mold;
- a mold driver driving one of the first and second molds toward and away from the other one to allow the first and second molds to switch between an open state and a closed state;
- and
- a resin feeder feeding a base material-molding resin containing a foaming agent that forms the base material, wherein
- the one of the first and second molds includes a main mold part, a separate mold part separate from the main mold part, and a relative movement mechanism moving the separate mold part relative to the main mold part in a driving direction of the mold driver.

A resin molding method for molding a resin product including a base material, the base material including a foamed layer and being made of a resin, the method comprising:
- preparing first and second molds;
- a resin feeding step of feeding a base material-molding resin to a base material-molding surface of the second mold, the base material-molding resin containing a foaming agent that forms the base material;
- a base material molding step of clamping the first and second molds to mold the base material after the resin feeding step;
- and
- a base material foaming step of, when the first and second molds are to be opened to foam the base material, moving a main mold part and a separate mold part both forming one of the first and second molds relative to each other in a driving direction of a mold driver, the base material foaming step being performed after the base material molding step, the separate mold part being separate from the main mold part.
