Removal device for adhering sand in mold cavity of pig iron casting

Abstract

The invention discloses a removal device for adhering sand in a mold cavity of a pig iron casting. The removal device comprises an ignition box body, and a motor room is arranged at the center of thebottom wall of the ignition box body. A motor and a driving shaft are arranged in the motor room, and the top of the driving shaft is fixedly connected with a rotating sieve plate. A heating plate isarranged on the bottom wall of the ignition box body, and an igniter, a gasoline pipe, a suck-back water pipe and a drain pipe are arranged on the side wall of the ignition box body in sequence. The suck-back water pipe and the drain pipe communicate with a water storage box, and the gasoline pipe is connected with a pressure pump and the bottom position of a gasoline tank. A sealing cover body isarranged at the top of the ignition box body. The removal device is specially aimed at the difficult problem that the adhering sand on the inner wall of the casting with a complex mold cavity structure cannot be cleaned. The gasoline is fully infiltrated into the surface of the casting and then is ignited to carbonize grease on the surface of the casting, so the adhesion between the adhering sandand the surface of the casting is greatly reduced. Moreover, the negative pressure phenomenon during fire extinguishing is utilized to enable the suck-back water pipe to wash and cool the casting, sothe removal efficiency and removal effect of the adhering sand are greatly reduced, and the cleanliness of the inner part of the mold cavity of the casting is ensured.

Description

technical field [0001] The invention relates to the technical field of surface treatment of pig iron castings, in particular to a device for removing sticky sand inside a mold cavity of pig iron castings. Background technique [0002] Pig iron castings are prone to sand sticking during the casting process, and some castings will be stained with grease after some rough machining, resulting in more serious casting sand sticking. For the treatment of sticky sand on the outer surface of the casting cavity, the prior art generally adopts the method of washing with gasoline and then drying. However, for the sand sticking on the surface of the casting cavity, the prior art can only be washed with a nozzle, and then manually wiped after washing. The final removal time is long and the removal rate is low, which needs to be improved urgently. Contents of the invention [0003] The object of the present invention is to solve the shortcomings in the prior art, and propose a device fo...
