Molding apparatus

摘要

This invention relates to a molding apparatus capable of producing flashless molded parts due to a perfect surface-to-surface mating of a pair of molds. The molding apparatus comprises an upper holding means for holding at least one upper mold having a path in which a moldable material is passable, and a lower holding means for holding at least one lower mold having a cavity, wherein a certain amount of fluid substance is filled between a bottom surface of the lower mold and the lower holding means, thereby the lower mold being floatable on the fluid substance and movable along the lower holding means, subsequently a joint between the upper mold bottom surface and the lower mold top surface being realized perfectly due to a back pressure of the fluid substance.
