MOLDING DIE AND MOLDING METHOD

摘要

A molding die for molding a foam molding in a cavity constituted in the interior by matching a stationary die and a movable die, the cavity being able to be filled with molten resin, and the foam molding being produced using counter-pressure. A seal material for sealing the pressurization area for the counter pressure technique between the stationary die and the movable die is provided to the molding die, and the seal material is constituted of an elastic foam that has open cells.

主权项

1. A forming mold configured to manufacture a foam-molded product, by molding, in use of a counter-pressure method, the foal-molded product that is obtained by feeding molten resin into a cavity formed within a fixed mold and a movable mold mated together,
wherein a seal material that seals pressurized air used in the counter-pressure method between the fixed mold and the movable mold is composed of an elastic foam material having interconnected cells.
