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.
Claims12
A resin molding device for molding a resin product including:
- a resin base material that includes a foamed layer and a non-foamed skin layer covering an entire surface of the foamed layer;
- and a skin material, 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 to the base material-molding surface, wherein
- the first 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 the mold driver,
- the main mold part has a skin material placement surface on which the skin material is to be placed, and
- the separate mold part has an exposed portion-molding surface which molds an exposed portion of the base material exposed from the skin material.

A resin molding method for molding a resin product including:
- a resin base material that includes a foamed layer and a non-foamed skin layer covering an entire surface of the foamed layer;
- and a skin material, the method comprising:
- preparing first and second molds, the first mold including:
- a main mold part having a skin material placement surface on which the skin material is to be placed;
- a separate mold part separate from the main mold part and having an exposed portion-molding surface which molds an exposed portion of the base material exposed from the skin material;
- and a relative movement mechanism moving the separate mold part relative to the main mold part in a driving direction of a mold driver;
- 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 the main mold part and the separate mold part both forming one of the first and second molds relative to each other in a driving direction of the 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.
