Abstract:
1. A molding machine comprising: a vertically oriented longitudinal axis; lower mount base having a mount surface; a lower mold having a contact surface configured to contact a lower surface of a previously molded base member, wherein the molding machine is configured to axially compress the contact surface of the lower mold and the lower surface of the base member together with respect to the longitudinal axis; and a first injection device including: wherein the first mold is configured such that at least a part of a cavity is defined by the lower mold and the lower surface of the base member when the lower mold contacts the lower surface of the base member; wherein the valve is movable within the injection nozzle between a first position where fluid communication between the injection nozzle and the cavity is restricted by the valve and a second position where fluid communication between the injection nozzle and the cavity is established; wherein the valve is configured to transition from the first position to the second position as a result of a pressure of a molten resin within the injection nozzle rising above a predetermined value; and wherein the tubular injection nozzle of the first injection device is configured to inject a molten resin vertically upward into the cavity when the valve is in the second position, so that a resin product molded by the resin injected into the cavity is fixed to the base member.
