Abstract

The invention provides a core shooting device of an ultra-large type core shooter and a control method of the core shooting device, and relates to the technical field of casting equipment. The core shooting device of the ultra-large core shooter comprises a bracket, a pressure head, a low-pressure air source and a high-pressure air source, a lifting source for driving the pressure head is arranged on the bracket; and the low-pressure gas source and the high-pressure gas source are connected with the pressure head through the sand shooting pipeline assembly. The control method comprises the following steps that before sand shooting, the low-pressure control valve is opened, the high-pressure control valve is closed, and the sand shooting valve is closed; the sand shooting valve is opened, low-pressure sand shooting is carried out, and the low-pressure sand shooting time is t1 seconds; the high-pressure control valve is opened at t1-n seconds, the low-pressure control valve is closed at t1 seconds, and low-pressure and high-pressure switching sand shooting is implemented; the high-pressure control valve is continuously opened, high-pressure sand shooting is carried out, the high-pressure sand shooting time is t2 seconds, the high-pressure control valve is closed at t2 seconds, the sand shooting valve is closed, and sand shooting is finished. The technical effect of sand shooting molding of the large sand core is achieved.

Description

technical field [0001] The invention relates to the technical field of casting equipment, in particular, to a core shooting device of a super-large core shooting machine and a control method thereof. Background technique [0002] The core shooting machine is mainly used for the shooting of large-scale sand cores such as locomotives, marine engine cylinder cores, and rear axle sand cores in the automotive industry. For the existing sand cores of large castings of more than 2 tons, the traditional domestic core-making processes are hand-made, self-hardening sand furan resin processes, etc., and sand-shot molding cannot be realized. [0003] The maximum core-making weight of the core-shooting machine in the prior art is less than 800Kg, but the amount of large-scale sand cores used for locomotives, marine engine cylinder cores, and rear axle sand cores in the automotive industry is usually 2000kg-3000kg. One of the difficulties lies in the core shooting device. [0004] There...
