The injection valve can be supported in an upright or horizontal position at the top of the rotary table, and a cap nut screwed onto the tip of the injection valve, which is supported in a horizontal position by a rotary table, can be tightened or removed using a spanner and a cylinder. If you do this, the injection valve, which is supported upright on the injection glaze, is supported in a horizontal position for disassembly and adjustment, and after the disassembly and adjustment is completed, it is supported again in an upright position on the injection glaze. In addition, the injection valve can be disassembled and adjusted from the top of the injection box. Therefore, operations such as supporting the injection valve upright on the upper part of the injection box, or supporting it horizontally for disassembly and adjustment, and disassembling and adjusting the injection valve can be easily performed.
