A conical sand making machine rolling mortar wall high-frequency vibration pouring mold and casting process

Abstract

The invention relates to a high-frequency vibration casting mold of a conical sand maker rolling mortar wall and a casting process capable of achieving the effect of no shrinkage cavity and effectively improving the cast density during casting feeding of the conical sand maker rolling mortar wall. The high-frequency vibration casting mold is characterized in that a sand box is located on a high-frequency vibration platform; the height of a rolling mortar wall forming mold cavity in the sand box is smaller than the height of a casting riser or the volume of the forming mold cavity is smaller than the volume of the casting riser. The casting process comprises the following steps: casting high chromium cast iron into the rolling mortar wall forming mold cavity and the casting riser, then carrying out high-frequency vibration on the high-frequency vibration platform, and cooling to obtain the high chromium cast iron rolling mortar wall with a high density. The high-frequency casting mold and the casting process have the advantages that firstly, the wear resistance of the high chromium cast iron rolling mortar wall is effectively improved, and the sand making cost is greatly reduced; secondly, the feeding effect is good, the cast is high in density, and the occurrence of damage phenomenon is avoided; and thirdly, the wear resistance, the shock resistance and the service life are increased by nearly 5 times, and unexpected technical effects are achieved.

Description

technical field [0001] The present invention relates to a conical sand making machine rolling mortar wall high-frequency vibration pouring mold which can obtain no shrinkage cavity and effectively increase the casting density in the casting feeding process of the cone sand making machine rolling mortar wall and casting The technology belongs to the field of casting. Background technique [0002] CN102380579A, the name "a casting method for rolling the wall of the mortar or rolling the wall of the mortar", includes the following steps: 1) Prepare the metal mold: design the shape of the inner and outer metal molds according to the shape of the casting, leave sand covering and machining allowance during the design, and use ordinary Carbon steel molding, formed by machining; 2) Preparation of sand covering: sand covering is composed of the following raw materials in parts by weight, 80-90 parts of standard sand, 3-5 parts of montmorillonite, 2-2 parts of attapulgite 3 parts, 1-...
