The movable mold mounting plate 1 moves in the direction of the arrow 2, and the mold is opened. When the mold is fully opened, the ejector/linder 2 is operated to move the stripper plate 3 in the direction opposite to the arrow to drop the molded product. Furthermore, in order to close the mold from the time of mold release (FIG. 2), the above-mentioned operation may be reversed. In other words, eject cylinder 2
(1) to move in the direction of the arrow, then move the 4L mounting plate 1 in the opposite direction to the arrow to close the mold.

付板の移動敏が犬である。In the mold release mechanism of the conventional molding machine as described above, the direction of movement of the stripper, etc. of the mold release reservoir is opposite to the direction of movement of the movable mold mounting plate when opening and closing the mold. Therefore, there are drawbacks such as the inability to shorten the short cycle of the molding machine. In addition, the opening range of the mold requires at least a space (t2) for the movable part of the stripper for mold release (t4) from which the molded product can easily fall, so the movable side mold mounting plate must be moved Satoshi is a dog.

Figures 3 and 3 are diagrams showing the state of the collar when it was released, and Figure 4 is a diagram showing the state of the rill type 11.1.

That is, in contrast to the conventional method in which the core is fixed to the mold and the stripper plate moves when there is damage caused by molding, in the present invention, the stripper plate is fixed to the mold and the core moves in the direction of movement of the conventional stripper plate 1. and move in the opposite direction. Therefore, the relative movement relationship between the core and the stripper plate is exactly the same as in the conventional molding machine, and the molded product is released by substantially the same means as in the conventional molding machine. In this way, the four main states shown in FIG. 4 are achieved.

The mold is closed by moving.
