PURPOSE: To prevent a resin from leaking from a support part of a mold at the time of molding by a method wherein a support plate for pressing and supporting a molding material by a pressing force irrespective of a pressing force applied to the mold is provided in the support part supporting the molding material.
CONSTITUTION: A support plate 2 for pressing and supporting a molding material supported on a support part 1 by a pressing force irrespective of a pressing force applied to a mold divided into two upper and lower parts is provided in the support part 1. The molding material is set and supported in the mold, and the mold is closed. After that, an eccentric cam mounted on a motor shaft provided on the top of the support plate 2 is rotated through an appropriate angle, whereby a downward pressing force is applied to the top of the support plate 2. In this manner, the support part 1 supporting the molding material is accurately pressed down, and a resin is prevented from leaking from the support part 1.
