Abstract

A hybrid core drive device according to an embodiment is provided with: a cylinder tube; a first cover member at one end of the cylinder tube; a second cover member at the other end; a rod which has a connection part to which the core is connected at one end of the cylinder tube, has an annular flange on the second cover member side, and penetrates the first cover member; the nut is fixed on the rod; a screw shaft penetrating the second cover member and the nut and provided so as to be insertable into the rod; a motor that rotates the screw shaft; a piston which is provided in the cylinder tube, through which the rod passes, and which is capable of sliding relative to the cylinder tube and the rod; and a connection part capable of connecting a pipe for supplying the operating fluid to a region surrounded by the cylinder tube, the first cover member, and the piston.

Description

technical field [0001] The present invention relates to a core driving device and a molding machine used when a mold having a core is used to manufacture a product. Background technique [0002] A die casting machine, which is an example of a molding machine, produces a product (die casting) by filling a cavity (cavity) in a mold clamped with a mold clamping device with a molten metal using an injection device. When a product has an undercut in the mold opening and closing direction, a mold having a core is used in addition to the fixed mold and the movable mold. [0003] When a mold having a core is used, a core driving device is provided for inserting the core into the stationary mold or the movable mold and for pulling the core out of the stationary mold or the movable mold. When pulling out the core from the stationary mold or the movable mold, a large driving force is required for the core driving device in order to pull the core away from the product. In addition, af...
