PROBLEM TO BE SOLVED: To suppress as much as possible temperature rising of a cylinder 21 even when the temperature of a molten resin is high. SOLUTION: The apparatus for manufacturing a molded product is provided with an upper and a lower molds 12 for forming a cavity 13, a hot runner block 17 in which a first resin passage 16 is formed, a gate nozzle 19 in which a second resin passage 18 communicating the first resin passage 16 and the cavity 13 is formed, a gate pin 20 for opening/closing the second resin passage 18, and a cylinder 21 for driving the gate pin 20. The cylinder 21 is installed to the hot runner block 17 via a cooling plate 45 having a passage 48 through which cooling water flows. COPYRIGHT: (C)2006,JPO&NCIPI
