Novel sand mold casting equipment and casting method thereof

Abstract

The invention belongs to the technical field of sand mold casting devices, especially relates to novel sand mold casting equipment and a casting method thereof, and aims at solving the problems that in the prior art, a large amount of manual labor and production time cost are consumed, the working efficiency is low, the casting mold precision is poor, moroever, a corresponding proportioning function is lacked, so that sand filling is troublesome, and meanwhile, excessive molding sand overflowing during sand filling is troublesome to recycle, so that the utilization rate of waste sand is reduced. The following scheme is disclosed: the novel sand mold casting equipment comprises a casting sand box, wherein supporting legs are arranged at the four corners of the outer wall of the bottom of the casting sand box, a sand discharging pipe is arranged at the bottom of the casting sand box, and a sand discharging valve is installed on the sand discharging pipe. According to the invention, by starting a stirring motor, the function of stirring a proportioning box can be realized, so that proportioning is facilitated, and during sand filling, a sieve screen can be driven to move back and forth at the same time, and a vibration effect is realized, so that refining for molding sand is facilitated, a high automation degree is achieved, the manual operation intensity is reduced, and the casting precision is improved.

Description

technical field [0001] The invention relates to the technical field of sand casting devices, in particular to a novel sand casting equipment and a casting method thereof. Background technique [0002] Sand casting is a casting method that produces castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time. [0003] Traditional sand casting is mostly manual molding. The specific molding process is: put the mold of the sand casting device into red sand for burial, take it out, scrape the mold plane flat, then sprinkle the parting sand, put it on the sand box, and add the pouring manually. Put the mouth and riser into red sand for compaction, then...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems in the prior art that consume a lot of manual labor and physical strength, production time cost, low work efficiency, poor mold precision, and lack of corresponding batching functions, which lead to troublesome sand filling and overflow during sand filling. It is troublesome to recycle molding sand and reduce the utilization rate of waste sand, so a new type of sand casting equipment is proposed
