PROBLEM TO BE SOLVED: To provide an injection molding apparatus configured to prevent a gate from being clogged with molten resin when the thickness of the gate is reduced and an opening cross section area to a cavity is reduced in order to adjust an inflow amount, in the injection molding apparatus including the cavity formed by two molds for injection molding and a flow passage of the molten resin connected by a plurality of gates.SOLUTION: A flow rate adjustment part 8 opened with a predetermined thickness and a solidification suppression part 9 having an opening area smaller than the flow rate adjustment part 8 are provided so as to extend in a flow direction of molten resin, in a connection part having small opening area of the connection parts of a plurality of gates 6. Accordingly, a distance to the center of the gate is increased. |
