This is because the carts that make up the conventional mold exchange system do not have the function of changing the direction of the mold.

Therefore, it is necessary to set the mold storage direction of the mold storage section so as to correspond to the mold setting direction of the molding machine.

This can be achieved relatively easily if the molding machines are arranged only on one side of the mold transfer path in the molding line, since the mold setting direction of each molding machine is the same direction.

However, if molding machines are arranged on both sides of the mold transfer route, the mold setting directions of the molding machines on both sides are opposite directions that are point symmetrical with respect to the cart located on the transfer route. become. Therefore, in this case, there is a mold storage part whose mold storage direction is set to correspond to the mold setting direction of the molding machine on one side, and a mold storage part whose mold storage direction is determined to correspond to the mold setting direction of the molding machine on the other side. Therefore, it is necessary to provide a mold storage section in which the direction in which the molds are stored is determined, which is difficult.

In the present invention, no matter which direction the mold is stored in the mold storage section, it is possible to reliably set the mold in the molding machine as the input source after the mold is transported on the trolley. The purpose is to
