PURPOSE:To contrive to simplify structure in a movable cylinder type injection molding machine for synthetic resin, etc. by arranging an injecting member on the upper plate of a moving frame, connecting the cylinder of a pressure device to the lower plate thereof and opposing it to the fixed plate. CONSTITUTION:First, the surface plate 16 synchronizing with a rod 18 is lifted quickly by the operation of the quick feed apparatus 17 to close the male and female dies 19, 20. At this time the ram 8 also rises to suck working oil from the oil tank 24 into the pressure chamber 10. When pressure oil is supplied from the in-out port 14 to the pressure chamber 10, the movable cylinder 9 falls, the lower moving plate 7, the columns 3, the upper moving plate 5, which are connected to each other, are lowered together. The injection member made by the screw shaft 6 arranged in the middle of the upper moving plate 5 injects molten resin 26 at the edge by the amplified pressure in the heating cylinder 22 into the cavity 25. Accordingly, the pressure device for the special use of injection can be eliminated, the injection pressure and the die clamping force are used simultaneously in common. This machine is powerful, reliable, and the processes are simplified. |
