MOLDING OF RESIN MOLDED PRODUCT

摘要

PURPOSE: To prevent the local lowering of crosslinking density at the part under the liquid level of a high temp. liquid of a molded container while preventing the generation of the phenomenon such as a void caused by vacuum degassing. CONSTITUTION: A thermosetting resin mixed with a crosslinking agent is heated and pressed by a split mold 2 to mold a resin molded product being a container in which a high temp. liquid is charged so that the liquid level thereof is set to a predetermined position or less. The thermosetting resin is arranged at the position of the cavity 3 of one mold corresponding to the bottom part of the container. Next, the clamping of the split mold 2 is started. The cavity 3 becomes airtight in the mold clamping process and, after the thermosetting resin passes the position of the cavity 3 of the split mold 2 corresponding to the predetermined position of the container to be molded, the vacuum degassing of the cavity 3 is started and subsequently completed simultaneously with the completion of the clamping of the split mold 2.
