METHOD AND APPARATUS FOR CLEANING MOLD, MOLDING METHOD AND MOLDING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a mold cleaning method large in cleaning cycle, extending the life of a mold and simply cleaning the mold in a short time, a mold cleaning apparatus, a molding method having long maintenance cycle and a molding machine therefor.

SOLUTION: The mold 2 is placed on a receiving stand 1 and an electrode 4 having a gas jet orifice 3 is provided in opposed relation to the receiving stand 1. The electrode 4 is allowed to approach the molding surface 5 of the mold 2. Gas is supplied to a gas flow channel 6 provided in the electrode 4 under pressure near to atmospheric pressure to communicate with the gas jet orifice 3 from the gas supply device 7 to be sprayed on the molding surface 5 from the gas jet orifice 3. Plasma 9 is produced between the mold 2 and the electrode 4 by applying a high frequency voltage to the receiving stand 1 from a power supply 8. Active particles formed in the plasma 9 are reacted with the contaminant on the molding surface to remove the contaminant to clean the mold.
