Problems solved by technology

The water glass sand core has the following disadvantages: 1. Poor dedispersion, which will cause cracks when the casting solidifies and shrinks
Second, poor collapsibility will make it difficult to clean casting core sand with complex shapes, increasing labor intensity and production cycle

Embodiment Construction

[0011] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0012] see figure 1 , a technical device for enhancing the yield and collapse of the core sand, comprising a core box 1, surface sand 2, wire mesh 3, core bone 4 and mixed sand 5, the surface sand is laid flat on the surface of the core box, and the wire mesh is inlaid On the surface of the surface sand, core box 1 is provided with core bone 4 , and mixed sand 5 is placed in the cavity in the middle of core box 1 . The wire cross section of the barbed wire mesh 3 is 1-5mm. The mixed sand 5 is composed of a volume mixing ratio of sawdust and surface sand of 1:1

[0013] The working principle of the present invention is: firstly, the present invention spreads the mixed surface sand on the surface of the core box for 15-50 mm (the thickness of the core sand is determined according to the volume of the sand core). Inlay the barbed wire on the surfac...

Abstract

The invention discloses a technical device for enhancing the deformability and collapsibility of core sand. The technical device comprises a core box, facing sand, a wire gauze, a core bar and mixing sand, wherein the facing sand is laid on the surface of the core box; the wire gauze is inlaid in the surface of the facing sand; the core bar is arranged in the core box; and the mixing sand is placed in a cavity at the middle in the core box. Through the wide application of the technology, the cracks of a casting are reduced by more than 80% compared with an original casting, and meanwhile the collapsibility of the core sand can be improved, and the labour intensity of manual sand cleaning for the same casting is reduced by 90%, so that great benefits are created for a factory.

Description

technical field [0001] The invention relates to the field of water glass, in particular to a device for enhancing the yield and collapse of foundry sand. Background technique [0002] The use of water glass is very extensive, almost throughout all sectors of the national economy. In the chemical system, it is used to manufacture various silicate products such as silica gel, white carbon black, zeolite molecular sieve, sodium metasilicate pentahydrate, silica sol, layer silicon and instant powdered sodium silicate, potassium sodium silicate, etc. Basic raw material for silicon compounds. In economically developed countries, more than 50 kinds of deep-processing products using sodium silicate as raw materials have been developed, some of which have been used in high-tech, fine-tech fields; in light industry, it is an indispensable raw material for detergents such as washing powder and soap. It is also a water softener and a sedimentation aid; it is used in dyeing, bleaching ...
