AI Technical Summary

Technical Problem

Titanium alloy sand casting lags behind in automation improvements, has poor mold self-hardening ability, is prone to sand loss and safety hazards when manually removing molds, makes product quality difficult to control, results in high labor intensity for workers and low production efficiency.

Method used

Design a sand mold that includes a base plate, outer box, core and telescopic mechanism. The telescopic mechanism drives the movable block to move on the outside or inside of the molding surface to realize the filling and removal of molding sand. This avoids manual hammering, improves the controllability of mold removal and the stability of the casting mold, and is suitable for automated production lines.

Benefits of technology

It improves the controllability of mold taking and the stability of casting, reduces the labor intensity of workers, improves the working environment, increases production efficiency and product quality stability, and increases production capacity.

Abstract

The application relates to a sand mold and a sand mold forming method in the technical field of casting processing. The sand mold comprises a bottom plate, an outer box arranged on the bottom plate, a core arranged in the outer box and supported on the bottom plate, a forming surface formed outside the core, a cavity formed inside the core, a plurality of holes arranged on the core and connecting the forming surface and the cavity, a movable block slidably connected in the hole, and a telescopic mechanism arranged in the cavity and used for driving one end of the movable block to extend to the outside of the forming surface or contract to the inside of the forming surface. The application improves the controllability of mold taking, improves product stability, improves the safety factor of box turning, makes the compactness of the casting higher, reduces the labor intensity of workers, improves the working environment of workers, and improves the production efficiency and stability of product quality.
