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
The present invention relates to a kind of waterglass field, a kind of specifically a kind of dress for strengthening foundry sand deformability and collapsibility
Put.
Background technology
The purposes of waterglass widely, almost throughout each department of national economy.Manufacture is used in chemical system
Silica gel, white carbon, zeolite molecular sieve, metasilicate pentahydrate sodium, Ludox, layer silicon and instant powdery sodium silicate, sodium potassium silicate etc. are each
Silicates product is planted, is the base stock of silicon compound.In developed country, the deep processing series with sodium metasilicate as raw material
Product has developed to more than 50 kinds, and some have been applied to high, precision and frontier sciemtifec and technical sphere；It is the washing such as washing powder, soap in light industry
Indispensable raw material in agent, is also water softener, settling agent；It is used for assisting-dyeing, bleaching and sizing in textile industry；In machine
Casting, emery wheel manufacture and anticolodal etc. are widely used in tool industry；It is used to manufacture quick hardening cement, acidproof in building trade
Cement water-proof oil, soil-solidified-agent, refractory material etc.；Silicon element fertilizer material can agriculturally be manufactured；Additionally may act as oil catalysis to split
Exotic material, anticolodal, the water such as the silica-alumina catalyst of change, the filler of soap, the adhesive of corrugated paper, laboratory crucibles
Softening agent, detergent builders, refractory material and ceramic raw material, the drift of textile, dye and slurry, mine ore dressing, waterproof, leak stopping,
Fire retarding wood protection, food antiseptic and preparing adhesive etc..Water-glass sand coremaking puts mixed waterglass core sand in core box model into,
Steel arbor is put in centre, core working face is pounded with instrument hardened with CO2 after reality, then to go out core from core box stand-by.Water glass
Glass core is suffered from the drawback that：One, it is poor to move back scattered property, and casting solidification can be caused to crack when shrinking.Two, collapsibility is poor, can lead
Cause complex-shaped foundry goods core sand to be difficult to clear up, increase labour intensity and production cycle.
The content of the invention
It is an object of the invention to provide a kind of technique device for strengthening its core sand deformability and collapsibility, above-mentioned to solve
The problem proposed in background technology.
For achieving the above object, the present invention provides following technical scheme：
A kind of technique device for strengthening its core sand deformability and collapsibility, including core box, facing sand, wire netting, arbor and mixed
Sand is closed, described facing sand is laid in box surface, and wire netting is embedded in facing sand surface, arbor is provided with core box, mixed sand is placed
In core box in middle cavity.
As further scheme of the invention：Described wire netting iron wire section is 1-5mm.
As further scheme of the invention：Described mixed sand is by sawdust and the volume mixture ratio 1 of facing sand：1
Compared with prior art, the invention has the beneficial effects as follows：By the extensive application of this technology, crackle and the original of foundry goods
To compare, more than 80% is reduced, meanwhile, the collapsibility performance of core sand is improved, one foundry goods of identical, the labor of Gong Ren Cheongju sand
Fatigue resistance reduces 90%, and to factory good benefit is created.
Description of the drawings
Fig. 1 is the structural representation of the technique device for strengthening its core sand deformability and collapsibility.
In figure：1st, core box, 2, facing sand, 3, wire netting, 4, arbor, 5, mixed sand.
Specific embodiment
The technical scheme of this patent is described in more detail with reference to specific embodiment.
Refer to the technique device of Fig. 1, a kind of its core sand deformability of enhancing and collapsibility, including core box 1, facing sand 2, iron wire
Net 3, arbor 4 and mixed sand 5, described facing sand is laid in box surface, and wire netting is embedded in facing sand surface, core box 1 and is provided with
Arbor 4, mixed sand 5 is placed in the cavity in the middle of in core box 1.The described iron wire section of wire netting 3 is 1-5mm.Described is mixed
Sand 5 is closed by sawdust and the volume mixture ratio 1 of facing sand：1
The present invention operation principle be：Mixed facing sand is first laid in box surface 15-50mm (according to core by the present invention
Volume size determine core sand thickness).Wire netting is embedded in into fresh sand surface, (placement of wire netting can root to strengthen sand core strength
According to the volume size of core, shape is determined).Put arbor.Facing sand and sawdust mixing are mixed into uniform into mixed sand, the sky of centre is placed on
In chamber.Uniformly hardened with CO2 gases.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, in the ken that one skilled in the relevant art possesses, can be with the premise of without departing from this patent objective
Make a variety of changes.
