MOLDING DIE INCLUDING CAVITY HAVING DUAL GATE

摘要

PURPOSE: A molding die including a cavity having a dual gate is provided to make molding resin have a uniform moving speed wherein the molding resin is supplied from a cavity bar having cavities of a matrix type to each cavity, by forming gates at both side surfaces of the cavity so that air vents are respectively installed in four corners of the cavity. CONSTITUTION: A port(112) is formed in a port block(114). A plurality of cavities are disposed in cavity bars(124) formed at right and left sides of the port block. A lower die(110) includes a space block(126) surrounding the port block and the cavity bars. The lower die is fixed in a lower body. An upper die is vertically separated from the lower die. The upper die is fixed in an upper body. Two gates(118) are formed on both side surfaces of a cavity(120) and in the direction the cavities are disposed. Each gate is connected to the port of the port block through a runner(116) so that molding resin is supplied through a dual gate.
