Abstract

PURPOSE: To provide fine holes accurately when resin is molded and a molded product having many stamped holes is manufactured by a method wherein the timing for stamping the hole is regulated according to their positions.
CONSTITUTION: When gelled molding material is supplied and molded between an upper mold 1 and a lower one 2 and the molded product 3 having a number of stamped holes are manufactured by a number of pins 4 and a driving source 5, the drive timing of the driving source is shifted and regulated. For that purpose, for example, the operation timing of a stop value 9 for the oil pressure supplied to the driving source 5 is shifted according the position of the hole. Because the pin must be stamped for a short time when the gelled molding material is charged in the mold and then cured and the charging time and the distance from the oil hydraulic source must be corrected as they differ with the position of the hole.
