ｆｌ限される問題がβった。A conventional injection molding machine is provided with a first ejecting plate and a second ejecting plate, and an ejecting pin is provided on each ejecting plate to protrude.
+ Raise the first ejector plate located on the mounting plate side and remove the Kazuhito Suguru runner etc. with the ejector pin, then raise this first ejector plate, push up the second temporary ejector, and remove the ejector pin. f'F: The product was rarely pushed out by moving (Japanese Patent Publication No. 25452/1989). According to this conventional example, the operation of the second ejection plate is dependent on the operation of the first ejection plate, and the operation of the second ejection plate is 1f.
The fl-limited problem was β.

動＋段によシロラドが移動可能であり。In the injection molding machine of the present invention, the supporting plates of the mantissa plates are arranged in one arrangement with a fixed gap between them. Of these, the one closer to the moving side template is bound to the first support plate 2
If the movable side is attached to the second support plate closer to the plate, the gap between both plates is equal to or larger than the stroke of the second support plate. Both plates remain at FilG 7'L for a distance such that the first support plate does not follow the movement of the second support plate. ■The first support plate has a force protruding from either the ejector pin or the operating rod, and the second support plate has a force protruding from it, and the other force passes through the first support plate. 1. This operating rod includes an ejector pin, a sprue lock pin, a sleeve for gate cutter, a presser for pressing the bath melt resin in the thinner, etc.゛In addition, in the case of wedge fishing, the board has at least two A2l1+ holes lined up on the circumference, and the insertion hole that meets the second through hole is the second support. It is installed through the plate. The Shirorad can be moved by two rotations driven + stages mounted on the circumference.
