Resin molding equipment

Abstract

Abstract PURPOSE:To efficiently mold a molded article with smaller gate mark by a method wherein a gate plate with a gate window is provided between a mold and a runner so as to cut off the molded product from a gate by shifting the gate plate after molding. CONSTITUTION:Molding material is supplied through the gate window 19 of a gate plate 15 in molding dies 3 and 4. After molding, the gate plate 15 is shifted in the direction indicated with the arrow B by shifting a driving rod leftward through the actuation of power source so as to cut off the molded part 41 from the runner part 42 of a runner 11. Because the end edge of the molded part 41 is sheared off by the boundary surface of a gate part 43, the molded part with a gate mark, the surface sheared off of which is so smooth as not to necessitate finishing treatment, is efficienctly obtained.
