PURPOSE:To enable good quality products to be molded even in the case of bad terms in material selection and mold configuration by controlling the cavity within a mold through performing a mold inclination during the filling process of a melted material into the cavity, and besides, adding vibration to the mold. CONSTITUTION:By adjusting the stroke of both coming up and down hydraulic cylinders 24, 24', an upper mold 28 can be inclined by inclining a movable disc 26. For this reason, a guide hole 27 provided on the movable disc 26 is made to be a configuration wherein the diameter becomes large as it goes from the central part to both end parts. And, as a vibration adding command (d) is outputted from a computer 50 to a controller 49', the controller 49' drives a motor 46 so as to rotate a disc 47, and a lever 45 is swung about the swinging fulcrum P via a link 48, as a result, the piston 41' of a vibration adding cylinder 41 is reciprocated. The bottom side and rod side are lubricated and drained alternately, and the piston 24a of the coming up and down cylinder 24 is reciprocated, thus, the movable disc 26 is added with vibration in order to vibrate the upper mold 28. |
