Abstract

The invention discloses an improved die-casting machine supercharging device. The improved die-casting machine supercharging device comprises a first base, a knock-out cylinder barrel, a two-speed energy accumulator, a second base and a supercharging energy accumulator; a knock-out piston rod and a floating piston which can axially move are arranged in the knock-out cylinder barrel; the floating piston is arranged on the rear end portion of the knock-out piston rod; an inner hole with an abrasion-resistant ring is added to the middle of the floating piston due to the accurate matching of the floating piston and a knock-out oil cylinder. A supercharging piston rod is accurately matched with the abrasion-resistant ring in a sliding mode to enable the front end of the supercharging piston rod to obtain the reliable support and accordingly the defect of the high pressure disturbance caused by the hydraulic oil supercharging of a front oil chamber can be effectively overcome, a conical hole of the floating piston can be rapidly and stably closed through the conical surface of the supercharging piston rod to enable the supercharging contact to be stable, the supercharging to be timely and the pressure building to be rapid, and accordingly the good quality of die-casting products is guaranteed.

Description

technical field [0001] The invention relates to the technology in the field of die-casting machines, in particular to an improved supercharging device for a die-casting machine. Background technique [0002] The die-casting machine is a series of industrial casting machines that hydraulically inject molten metal into the mold for cooling and forming under pressure, and obtain solid metal castings after the mold is opened. With the advancement of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles and household appliances, and starting from energy saving and saving raw materials, die-casting technology has achieved extremely rapid development. There are many classification methods for die-casting machines, which are divided into general-purpose die-casting machines and special-purpose die-casting machines according to the scope of use; divided into small machines (≤4000kN), medium-sized machines (400...
