Abstract

PURPOSE:To shorten required time for 1 cycle sharply and improve productivity by making advance of the partition plate during mold closing movement at the time of mold closing in low speed and making regression of the partition plate during mold opening movement when releasing. CONSTITUTION:In making a metal mold from a open state to close state, a movable mold board 5 is moved to the right by oil pressure acting on a piston 11 by supplying pressure oil to the port (a) of a mold opening and closing cylinder 10. Just before closing of the metal mold 21 after arriving at low speed from mold closing high speed through medium speed, a locking component 30a fits in a step 31c of a mold clamping ram 31 and the pressure oil is led to port (c) of a hydraulic cylinder 15. Then, partition plates 32, 32' move forward and pressure oil is supplied through a port (e) of a pressure receiving plate 9. A mold clamping ram 31 slides to the right to raise mold clamping pressure. On the other hand, in making mold opening movement, the pressure oil is extracted from the port (e) and supplied from a port (f). Then, the mold clamping ram moves to the left to switch the pressure oil to a port (d), and the partition plates 32, 32' get out of the hollow groove 32b. At this time, a compression column 30 also moves to the left and releasing of the male mold 20 is made at a specified distance off from the female mold 19.
