Abstract

The utility model discloses a casting sand mold for a special-shaped brick, comprising a sand mold internal model and a sand mold external model, wherein the sand mold external model is arranged outside the sand mold internal model, and each of six sides of the sand mold external model is provided with a sand mold plate. The casting sand mold for a special-shaped brick is characterized in that the sand mold internal model comprises a wooden model and a grooved wooden model; the wooden model is made according to the shape and dimension of the special-shaped brick; and the grooved wooden model is adhered at a groove at the bottom part of the wooden model, and two ends of the grooved wooden model are 25 mm longer than the internal and the external end surfaces of the bottom groove of the wooden model; the bottom part of the sand mold external model is symmetrically provided with four gates and risers, and the external surface of the sand mold external model is provided with a cooling device in which a refrigerant is filled. The casting sand mold for a special-shaped brick is easy in demoulding, the dimension of the special-shaped brick has small deviation, the casting quality of the special-shaped brick is greatly improved, and the production yield of the special-shaped brick is guaranteed.

Description

Special form brick casting sand mold

Technical field

The utility model relates to mould applications, especially a kind of special form brick casting sand mold.

Background technology

Along with the development of industrial production technology, since the sixties, the brick type develops into special form brick by common brick.The shape of special form brick mainly determines according to the needs of actual production, usually can be provided with re-entrant angle, acute angle or groove etc. on the special form brick, so the production technology of special form brick adopts cast molding usually.When special form brick adopts electric smelting AZS cast molding, must be by high warm casting one-shot forming, because the particularity of its moulding, forming process does not have the sintering process of common refractory, just there are not the semi-finished product before burning till yet, can't carry out preliminary examination to the geomery of product, so it requires to the sand mold shape-designing very high.The product that does not have good sand mold to produce, the sand mold shape-designing is unreasonable, and the feed liquid of watering in the die cavity can produce various defectives in cooling procedure, thereby causes product rejection.In addition, because special form brick is provided with re-entrant angle, groove etc., if adopt the cast molding of common whole mould mode, can cause the product can't depanning; If the employing Split type adhered because the moulding spool tile is complicated, can cause the cavity dimension deviation larger in the bonding process.

Summary of the invention

It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and the demoulding is easy, the special form brick that the special form brick dimensional discrepancy of cast molding is little casting sand mold.

In order to reach above purpose, the technical scheme that the utility model adopts is: this special form brick casting sand mold, comprise sand mold internal mold and sand mold external mold, the sand mold external mold is arranged on the outside of sand mold internal mold, six sides of sand mold external mold all arrange sand mould plate, it is characterized in that: the sand mold internal mold comprises wooden mold and groove wooden model, wooden mold is made according to the shape and size of special form brick, the groove of wooden mold bottom is bonded with the groove wooden model, the two ends of groove wooden model are than in the wooden mold bottom groove, 25mm is respectively stretched out in the outer face, the bottom of sand mold external mold is symmetrical arranged four dead heads, is provided with cooling device at the outer surface of sand mold external mold, is filled with refrigerant in the cooling device.

The beneficial effects of the utility model are: the first, by this casting sand mold and from the bottom casting, be convenient to the casting of product, and the demoulding is easy, and the special form brick dimensional discrepancy of cast molding is little; The second, the dead head area of this sand mold is relatively large, and casting has easily improved the casting quality of special form brick greatly; The 3rd, by cooling device is set, the refrigerant of the heat in the casting sand mold by cooling device can be passed fast, accelerate cooling, prevent substandard products and waste product, guaranteed the yield rate of special form brick.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 and Fig. 2 are the special form bricks 1 that needs cast molding in the present embodiment, and this special form brick 1 is hollow form, and the bottom arranges respectively groove on four limits.

Make the utility model with reference to accompanying drawing 3, Fig. 4, Fig. 5, Fig. 6.This special form brick casting sand mold, comprise sand mold internal mold 2 and sand mold external mold 5, sand mold external mold 5 is arranged on the outside of sand mold internal mold 2, it is characterized in that: sand mold internal mold 2 comprises wooden mold 3 and groove wooden model 4, wooden mold 3 is made according to the shape and size of special form brick 1, shape according to wooden mold 3 bottom grooves is made groove wooden model 4, and the groove wooden model 4 of making being bonded to the groove of wooden mold 3 bottoms, 25mm is respectively stretched out than the inside and outside end face of wooden mold 3 bottom grooves in the two ends of groove wooden model 4.Six sides of sand mold external mold 5 all arrange sand mould plate, and the bottom of sand mold external mold 5 is symmetrical arranged four dead heads 6, casting gate are arranged on four corners of casting product bottom by four dead heads 6, have realized the bottom casting from special form brick.Simultaneously, be provided with cooling device 7 at the outer surface of sand mold external mold 5, be filled with refrigerant in the cooling device 7, by refrigerant cast material etc. is cooled off, improved radiating efficiency, improved qualified casting.

When utilizing this sand mold to cast, at first according to shown in Figure 6, sand mold internal mold 2 is placed in the sand mold external mold 5, by dead head 6 the electric smelting AZS of high temperature is poured in the space between wooden mold 3 and the sand mold external mold 5, special form brick 1 is namely plastic after the electric smelting AZS cooling, has accelerated the cooling of electric smelting AZS in the cooling procedure by cooling device 7.After special form brick 1 moulding, wooden mold 3 and groove wooden model 4 are unloaded, and reusable.
