The SI mold is combined with the mold. Molded products are produced under pressure. In order to increase the efficiency of injection molding expansion, the movable mold is first moved quickly with a small amount of pressurized oil by a small s cylinder, and then by a large diameter cylinder. The metal mold is going to be released into the fixed mold with a large enough force.

The piston 3 fixed to the large-diameter cylinder 5 to which the ram 10 is fitted is fitted to the fast-forward cylinder 4 and pressurized oil is supplied to perform fast-forward. Therefore, in this rapid traversing process, the oil in the large oil cylinder 5 of the large S cylinder 5 must be balanced by relying on the pressurized oil also in the large cylinder 5 fitted with the ram 0. In other words, a large amount of oil is supplied to the large δ cylinder 5 by the amount of the fast-forward process. Reciprocating the new ram 10 every cycle not only results in loss of plowing power, but also in hydraulic tracts to prevent switching of the sugar level and preventing window panning at the start. It is also disadvantageous in terms of cost, such as the necessity of establishing a loose bite country route.

Is done. Then, in order to reduce the looseness and looseness of the explosion », the mold support» material 51 is provided with a cutout 7 4 across the screw hole 7 2, and the cutout 7 4 is to be cut. A port 73 extending parallel to the screw ring 71 is attached to the bran. As a result, the stroke range of the katsuru mold 51a due to the dimensions of the kana mold 51a and the fixed mold 62a can be raised. Next, the work of the apparatus of the present invention will be described. In the state shown in FIG. 3, the mold 51 is separated from the fixed mold 62 a and the molded product is taken out. Now, for the bottles that can quickly join the mold 5 1a to the fixed metal 6 2a, the oil chamber 43 of the fast-forward cylinder 40 is used as the hydraulic pressure source and the oil chamber 44 is oil-planted. Then, the piston 41 is pushed to the right, and the rod 41 supports the mold support 51 and the movable mold 51a quickly to the fixed mold 62a. At this time, the ram 48 does not move, and the next support member 51 protrudes from the hollow Φ 49 of the ram 48.
そ こで、 シ リ ンダ 5 4の下端油窆を油圧灘に接 « す ると 、 ピス ト ン 5 & によって ロッ ド 5 5を介して二 S 状の中 ϋ板 5 3が押 し上げら れ、 ラム 4 8の右纏面と 型支持部材 5 1 の左靖面との Sへ搏入される。 したが つて 、 ピス ト ン 4 8 a と ラ ム 4 8に油圧を作用させれ ば、 中權扳 5 3を介して型支持揮材 5 1 が右方へ押さ れるこ と となる。 すなわち 、 可動金型 5 1 a を固定金 S 6 2 a へ強 く 押付ける場合には、 早送り シ リ ンダ 4 0の油室 4 3 , 4 4 ま た は油室 4 4だけを油槽へ接練 し 、 大径シ リ ンダ 4 6の油室 4 7を油圧濛へ接練する と、 ラム 4 8が右方へ押さ れ、 油室 4 7へ送られる油 圧およびラム 4 8の受圧面積に対 し た力で可動金型 5 1 a が固定金型 6 2 a へ練付け られるこ と となる。 Therefore, when the lower end oil of the cylinder 54 is brought into contact with the hydraulic oil bath, the piston 5 & pushes up the S-shaped intermediate plate 53 via the rod 55. Then, it is injected into S on the right covering surface of the ram 48 and the left side of the mold supporting member 51. Therefore, if hydraulic pressure is applied to the piston 48 a and the ram 48, the mold supporting base material 51 is pushed rightward through the Nakagong No. 53. That is, when the movable mold 51a is strongly pressed against the fixed metal S62a, the oil chambers 43, 44 or only the oil chamber 44 of the rapid-forward cylinder 40 are connected to the oil tank. When the oil chamber 47 of the large-diameter cylinder 46 is kneaded with the hydraulic hum, the ram 48 is pushed to the right, and the hydraulic pressure sent to the oil chamber 47 and the pressure receiving area of the ram 48 are kneaded. The movable mold 51a is kneaded to the fixed mold 62a by the force acting on the movable mold 51a.

Very large kneading force is transmitted to the movable mold 51a. Therefore, it is not necessary to move the ram 48 in the rapid traverse path as in the conventional case, so that the ram 48 can be moved slightly by the mold kneading allowance (usually a few M is sufficient. With a small supply of pressurized oil needed for a few hundred a 醮, for example, 700 鱅 騸), a generous pulsating force can be obtained, and it is useful for saving power. In addition, quick stop of the mold supporting member 51 is effective, and a quick rise of the kneading force can be obtained. In addition, the mold kneading force is generated »The entire structure is a hydraulic plow mechanism, and no mechanical lubrication is required. Therefore, it does not require lubrication, so it is simple. Therefore, there are few failures and can withstand long-term use.
