Abstract

An electric injection device 1 of a die-casting machine is provided with: a rotatably held screw shaft 5; a nut 7 that is screwed onto the screw shaft 5 and that is driven forward and backward in accordance with the rotational drive of the screw shaft 5; an injection plunger 9 that is driven forward and backward in conjunction with the forward and backward movement of the nut 7; an injection electric servomotor 11 and a pressure-increasing electric servomotor 12 that rotationally drive the screw shaft 5; a one-way clutch 13 that is provided between the screw shaft 5 and the pressure-increasing electric servomotor 12; and a lubrication device 14 that rotates integrally with an outer ring 92 of the one-way clutch 13. The present invention lubricates the one-way clutch 13.

Description

technical field [0001] The present invention relates to an electric die-casting machine, and more particularly, to a lubricating device for a one-way clutch provided in an electric injection molding device for injecting and filling molten metal into a cavity of a mold. Background technique [0002] The die-casting machine drives the injection plunger equipped with the injection molding device to inject and fill a certain amount of molten metal materials such as aluminum alloy or magnesium alloy into the cavity of the mold to manufacture the die-casting products of the desired shape in each injection. molding machine. Like the injection molding machine that injects and fills plastic materials into the cavity to manufacture plastic products of the desired shape, the die-casting machine also undergoes a low-speed injection process, a high-speed injection process, and a pressurization process (called a pressure-holding process in an injection molding machine). process) to injec...
