Abstract
The utility model discloses a sand mould for casting a cold steel moulding plate casting cavity. The sand mould comprises a square sand mould body formed by silica sand; the sand mould body is internally provided with the casting cavity for forming a casting piece; and a cold steel moulding plate which can wholly cover the wall of the cavity is uniformly distributed on the wall of the casting cavity. The cold steel moulding plate forms the cold steel moulding plate casting cavity and is smooth in surface and good in hardness compared with a firebrick, so that the forming rate, the demoulding rate and the surface quality of large casting pieces can be greatly improved.
Description
Technical field
The utility model relates to a kind of Casting Equipment of metal alloy, relates in particular to large-scale copper alloy sand casting technique sand mo(u)ld.
Background technology
Generally adopt sand casting technique the cost huge fund also to be arranged by accurate centrifugal casting about the casting of large-scale metal alloy at present.The general not super 40KG of its foundry goods of centrifugal casting in above-mentioned two kinds of traditional casting methods, trace it to its cause centrifugal casting its need a metal mold, itself just there is huge technical difficulty in this large-scale its manufacturing of metal mold, and centrifugal casting needs the rotating metallic mold, if the designing cast single-piece reaches more than five tons, it is can't realize rotary heating fully that its weight of that metal mold will reach tens of tons, does not have exploitativeness.Although sand casting is applicable to the heavy castings manufacturing, present sand casting is for the moulding of heavy castings, and its casting chamber generally is made of the refractory brick veneer, often exists thus air gap, foundry goods compactness, cast(ing) surface to have the technological deficiencies such as a large amount of white points.
The Chinese utility model patent patent No. 201020535007.0 discloses a kind of sand mold casting device, and this sand mold casting device is the topotype that the mixed earth of reinforcing bar becomes with laying fireproof bricks, and quartz sand is layered on the casting model that make on the topotype surface.This kind casting model is exactly a kind of device that adopts the mixed earth of reinforcing bar and refractory brick to consist of the casting chamber, and it can not solve cast(ing) surface and have the technological deficiencies such as white point.
Summary of the invention
The utility model provides that a kind of surface quality of continuous castings is good, air gap content is little, the foundry sand moulds in the cold steel form casting chamber that demoulding success rate is high.
The foundry sand moulds in a kind of cold steel form casting chamber comprises the square frame-shaped sand mo(u)ld body that is made of quartz sand, is provided with the casting chamber that forms foundry goods in the sand mo(u)ld body, is evenly equipped with the cold steel form of comprehensive covering cavity wall on the cavity wall of described casting chamber.The cold steel form casting chamber that this kind adopts cold steel form to consist of, refractory brick is smooth relatively owing to the surface, and hardness is good, has improved greatly ratio of briquetting, demolding rate and the surface quality of heavy castings.
Evenly be densely covered with the buried air guide rope that enters in the quartz sand on the sand mo(u)ld body of described casting chamber cavity wall periphery, so that because of the casting cavity temperature aqueous vapor in the quartz sand that causes that raises, discharge the sand mo(u)ld body and prevent that this kind aqueous vapor from entering foundry goods.
The cold steel form casting chamber that the utility model adopts cold steel form to consist of, because the relative refractory brick in surface is smooth, hardness is good, has improved greatly ratio of briquetting, demolding rate and the surface quality of heavy castings.
Description of drawings
Be illustrated in figure 1 as the foundry sand moulds structural representation in the cold steel form casting of the utility model chamber.
The specific embodiment
A kind of cold steel form is cast the foundry sand moulds in chamber as shown in Figure 1, comprise the square frame-shaped sand mo(u)ld body 1 that is consisted of by quartz sand, be provided with the casting chamber 2 that forms foundry goods in the sand mo(u)ld body 1, be evenly equipped with the cold steel form 3 of comprehensive covering cavity wall on casting chamber 2 cavity walls, form cold steel form by the cold steel form 3 of comprehensive covering cavity wall and cast the chamber.
Evenly be densely covered with the buried air guide rope 4 that enters in the quartz sand on the sand mo(u)ld body 1 of casting chamber 2 cavity wall peripheries, be convenient to the aqueous vapor in the quartz sand is discharged sand mo(u)ld body 1.
Claims (2)
1. a cold steel form is cast the foundry sand moulds in chamber, comprise the square frame-shaped sand mo(u)ld body (1) that is consisted of by quartz sand, be provided with the casting chamber (2) that forms foundry goods in the sand mo(u)ld body (1), it is characterized in that: the cold steel form (3) that is evenly equipped with comprehensive covering cavity wall on the cavity wall of described casting chamber (2).
2. the foundry sand moulds in cold steel form casting chamber as claimed in claim 1 is characterized in that: evenly be densely covered with the buried air guide rope (4) that enters in the quartz sand on the sand mo(u)ld body (1) of described casting chamber (2) cavity wall periphery.
