No-mold casting method and equipment capable of automatically draining sand

Abstract

The invention discloses a no-mold casting method and equipment capable of automatically draining sand. A processed surface of a sand mold is downwards inclined or vertically arranged; the sand mold is cut through numerical control cutting equipment; and in the processing process, cut waste sand is naturally drained into a sand draining groove under the effect of self gravity. The equipment comprises a numerical control cutting device, a sand box station control device and a waste conveying belt, wherein the numerical control cutting device and the sand box station control device are fixed on the ground in parallel; a sand box mounted on the sand box station control device is positioned in a processing position of the numerical control cutting device; and the waste conveying belt is mounted between the numerical control cutting device and the sand box station control device, and is positioned below a sand mold processing station. The problems of cutter clamping by waste sand accumulation and cutter grinding can be solved without adding an injection device in the equipment or adopting the manual cleanness, so that the equipment is simplified, the manpower and the material resources are saved, and the no-mold casting production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of casting modeling without pattern casting, in particular to a method and equipment for forming without pattern casting capable of automatic sand discharge. Background technique [0002] The existing method of processing sand molds for non-pattern casting places the sand molds under the cutting knife, and the processing surface of the sand molds is set upwards. During the cutting process, the waste sand produced cannot be discharged naturally, resulting in the accumulation of waste sand between the knife and the knife. Grind knives. The solution in the prior art is to rely on manual cleaning or compressed air blowing and cleaning. Manual cleaning is time-consuming and laborious, which affects production efficiency; compressed air blowing and cleaning needs to increase the blowing device. The design cost and production cost of the blowing device, while increasing the energy and power consumption during prod...

Problems solved by technology

[0002] The existing method of processing sand molds for non-pattern casting places the sand molds under the cutting knife, and the processing surface of the sand molds is set upwards. During the cutting process, the waste sand produced cannot be discharged naturally, resulting in the accumulation of waste sand between the knife and the knife. grinding tool

The solution in the prior art is to rely on manual cleaning or compressed air blowing and cleaning. Manual cleaning is time-consuming and laborious, which affects production efficiency; compressed air blowing and cleaning needs to increase the blowing device. The design cost and production cost of the blowing device, at the same time increase the energy and power consumption during production, and finally increase the production cost of moldless casting

The third is that the waste sand blown up by the blowing device will pollute the working environment, and even sand particles will enter the transmission device of the equipment, causing wear of the transmission parts of the equipment and affecting the service life of the equipment
