In a state where the rod 45 is moved back into the cylinder 41 and output, the bottom block 44 of the cylinder 41 contacts the stopper 47 mounted on the rod cover 46. The four guide posts 21, 21 as the guides of the upper and lower plates 3 pass through the four corners of the upper and lower plates. The end of the guide post is fixed to the lower fixing plate 12 of the mold clamping device 1, and the bottom thereof is fixed to the mounting plate 23. The implementation of the use of the mold clamping device will be described by taking the above-mentioned mold clamping device 1 and the injection machine 6 as examples, and then describing the implementation of the injection mold. As shown in FIG. 5, the injection machine 6 is a horizontal injection type injection machine provided with a barrel 62 having an injection nozzle for injecting molten resin into a heat flow, and the hot runner is an upper mold member 60 formed in the mold clamping device 1. in. When the molding starts, the movable plate 11 is moved downward by the mold clamping cylinder 10. When the upper mold member 60 and the lower mold member 61 reach a preset distance, the movable plate 11 is temporarily stopped. Next, the barrel 62 is moved so that the injection nozzle 63 of the injection machine 6 is joined to form an inlet of the hot runner 60 1 in the upper mold member 60, and then the molten resin is injected. When a preset amount of melted resin is supplied to the inside (cavities) of the mold members 60, 61, the injection is stopped and then the injection machine 6 is ^ i.e. the mold (please read the precautions on the back before filling this page) ) Order ----- · --- line · This' paper size applies to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 476698 A7 B7 V. Description of the invention (9) The clamping device 1 is separated. Thereafter, the stationary movable member 11 is further moved downward 'and the mold members 60, 61 are completely brought into close contact. Therefore, the resin in the mold member diffuses into the cavity and is formed under pressure. After the formed resin is completely cured, the moving plate 11 is moved upward to separate the upper mold member 60 from the lower mold member 6 1. At this time, the mold 5 formed by curing the resin is supported on the lower mold member 61. In the next step, when the hydraulic oil in the normal output state is supplied to the ejection device 2 through the hydraulic pressure line control valve 40. When the cylinder 4 v 4 is pressed, the lever 45 is removed from the cylinder 4. As a result, the circle is pushed up, and the lower plate 3 mounted above the cylindrical hand guard portion 42 is also raised, as shown by the dotted line in FIG. 4. Therefore, the ejection pins 20, 20 are pushed out from the lower fixing plate 12, and the pushing-out plate 72 of the film release device 7 embedded in the lower mold member 61 is pushed up. Therefore, the ejection pins 71, 71 standing on the ejection plate 72 are projected from the surface of the lower mold member 61, and the mold 5 supported on the lower mold member is pushed upward to release the film. After the mold is removed from the film, the hydraulic oil supply circuit is reversed by the hydraulic circuit control valve 40 'to bring the hydraulic cylinders 4, 4 into the backward output state, so the rod 45 is moved backward into the cylinder 41. In Ningguo, the release pins 7 1 and 7 1 protruding from the lower mold member 61 are moved downward to the positions where their ends fit on the surface of the lower mold member 6 丨. Although in the foregoing embodiment, the hydraulic cylinder 4 is used as a drive for the upper and lower plates 3 of the ejection device 2 for vertical movement, the cam (please read the precautions on the back before filling this page).
