Title: Molding die
Inventor: TAKEUCHI YOSUKE
IPC: B32B9/00
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To lessen an adhesive force and thereby make it possible to improve mold parting properties when a part which comes into contact with a molding is hydrophobic by forming a surface layer consisting of a photocatalytic particle alone or a surface layer containing the photocatalytic particle on the molding face of a molding die, and making the mold face hydrophilic by photoexcitation. SOLUTION: The material for a plastic molding die is such as a variety of steel like carbon steel for mechanical structure. A layer containing a photocatalytic particle such as titanium oxide is formed on the surface of the molding die. If photoexcitation is given, a hydroxyl is chemically absorbed into the surface of the photocatalytic particle by photocatalytic effects or the hydroxyl is substituted with an organic group by the effects. Further, the water molecule of air is physically adsorbed into the hydroxyl to increase the amount of the physically adsorbed water, and thus the surface of the molding die becomes in creasingly hydrophilic to obtain a superhydrophilic surface. Once the surface has become superhydrophilic, this hydrophilic state is maintained without light emission for some time.  Consequently, the hydrophlic surface of the mold hardly adheres to the surface of a hydrophobic molding to facilitate the mold parting.
