A control means of a molding machine is designed so as to control molding cycles SA and SB for sequentially performing injection of molten resin into a product portion of a mold 1 to fill it therewith, cooling down and solidification of the filled molten resin, mold opening of the mold 1, taking-out of a molded product, and mold closing of the mold 1 as well as changing the shape of a molten resin filled region of the product portion in accordance with the shape of a molded product to be molded in the next molding cycle during the present one molding cycle. Therefore, it is possible to change the shapes of molded products without the need to stop the molding cycle.
Dispositif de commande d'une machine de moulage conçu pour commander les cycles de moulage SA et SB, de la façon suivante : injecter de la résine à mouler fondue dans la partie produit d'un moule 1 pour le remplir, refroidir et solidifier la résine fondue, ouvrir le moule 1, retirer le produit moulé, fermer le moule 1. Il permet aussi de changer la forme d'une section remplie de résine de la partie produit, au cours du cycle actuel, conformément à la forme d'un produit à mouler au cours du prochain cycle. Il est donc possible de changer les formes des produits moulés sans interrompre le cycle de moulage.
