AI Technical Summary

Technical Problem

In the prior art, when the resin sand core is heated, the molded sand core is deformed due to the inability to level; the mold is prone to sticking when the mold is started; and the high humidity of the resin sand causes the moisture to evaporate thoroughly, resulting in cracking of the sand core and poor molding quality.

Method used

A resin sand core heating mold starting device is designed, including a work table, a mold, a mold starting mechanism, a height adjustment mechanism, a vertical plate, a slide rod, a sliding table, a feeding mechanism and an anti-adhesive mechanism. By leveling the mold through the height adjustment mechanism, the anti-adhesive mechanism prevents the mold from being stuck, and the feeding mechanism dehumidifies the resin sand raw material to ensure the mold quality.

Benefits of technology

The mold leveling is achieved to prevent the resin sand core from deforming; the mold sticking phenomenon is reduced through the anti-adhesion mechanism; the feeding mechanism effectively dehumidifies, prevents the sand core from cracking, and improves the molding quality.

Abstract

The invention relates to the technical field of casting, in particular to a resin sand core heating and drawing device which comprises a workbench and a mold, the mold is installed in the center of the upper surface of the workbench, and a resistance wire is installed in the mold to heat the mold. The resin sand core heating and drawing device further comprises a drawing mechanism, a height adjusting mechanism, a vertical plate, a sliding rod, a sliding table, a feeding mechanism and an anti-sticking mechanism, the drawing mechanism is installed in the center of the bottom of the workbench, and a sand core in a mold is ejected out through the drawing mechanism; the height adjusting mechanism is vertically installed at the bottom ends of supporting legs of the workbench and adjusts the heights of the four corners of the workbench. The two vertical plates are fixedly connected to the left end and the right end of the upper surface of the workbench correspondingly. And kerosene can be sprayed according to the width of a mold cavity of the mold, so that kerosene waste is reduced, mold sticking is prevented, a resin sand raw material dehumidification function is achieved, cracking of the molded sand core during use is prevented, and the molding quality is guaranteed.
