Precoated sand mold casting sand box treatment device and treatment method

Abstract

The invention relates to the field of sand mold casting, in particular to a precoated sand mold casting sand box treatment device and treatment method. The precoated sand mold casting sand box treatment device comprises a base, the base is of an H-shaped structure, first sliding grooves are symmetrically formed in the top of the base, and moving blocks are symmetrically arranged at the top of thebase and slidably connected into the first sliding grooves; first hydraulic cylinders are fixedly mounted at the tops of the moving blocks, lifting plates are fixedly mounted at the output ends of thefirst hydraulic cylinders, second hydraulic cylinders are inserted in the lifting plates and rotationally connected to the lifting plates, and connecting frames of L-shaped structures are fixedly mounted at the output ends of the second hydraulic cylinders; and connecting rods are hinged to the sides, away from the second hydraulic cylinders, of the connecting frames, clamping plates of concave structures are hinged to the ends, away from the connecting frames, of the connecting rods, and third hydraulic cylinders are fixedly installed on the connecting frames and located below the connectingrods. The sand base in the sand box can be automatically cleaned, and the treatment device is suitable for popularization.

Description

technical field [0001] The invention relates to the field of sand casting, in particular to a treatment device and a treatment method for a film-coated sand casting sand box. Background technique [0002] Coated sand casting is a kind of high-quality selected natural sand as the sand base, through the special performance of the resin coating system and the most ideal technology, according to the technical needs of different users, strive to be in normal temperature performance, high temperature performance, collapsibility, The most perfect combination of fluidity and casting surface roughness, widely used in automobile engine, diesel engine, hydraulic parts and other industries. [0003] Sand box is needed for film-coated sand casting. Put the casting mold in the sand box, then put in appropriate amount of natural sand for compaction, and inject the metal solution into the mold to complete the sand casting. After the casting is cooled, put When the casting is taken out, the...

[0003] Sand box is needed for film-coated sand casting. Put the casting mold in the sand box, then put in appropriate amount of natural sand for compaction, and inject the metal solution into the mold to complete the sand casting. After the casting is cooled, put When the casting is taken out, the sand base in the sand box needs to be removed and cleaned so that the sand box can be used again. The conventional operation method is to manually turn the sand box upside down, and manually knock and clean it. The removal of the sand base in the sand box is time-consuming, labor-intensive, and labor-intensive, which reduces the efficiency of sand casting
