Embodiment 1

[0029] Please refer to figure 1 , a white mold assembly for metal liquid casting lost foam casting, including a first white module 1, a second white module 2, a filter screen 3 and an adhesive tape 4, and the filter screen 3 is placed in the first white module 1 and the second white module between the joints of the white modules 2, and seal the adhesive tape 4 to the joints of the filter screen 3 and the first white module 1 and the second white module 2.

[0030] Specifically, the filter screen 3 adopts a ceramic foam filter screen 3 .

[0031] Through the above technical solution, the problem of cracking due to the use of adhesives during the bonding of the white molds can be avoided, that is, it is only necessary to use adhesive tape 4 to seal the filter screen 3 and the first white module 1 and the second white module 2 . In addition, since the lost foam is cast under negative pressure, the filter screen 3 can be well connected with the first white module 1 and the second...

Embodiment 2

[0033] Further, in order to make the above solution have a better application effect in practice, another kind of white mold assembly for the lost foam casting of the metal liquid casting is also provided, see figure 2 As shown, the white mold assembly for the metal liquid casting lost foam casting includes a first white module 1, a second white module 2, a filter 3 and an adhesive tape 4, and the filter 3 is placed in the first white module 1 and the junction of the second white module 2, and the two ends of the filter screen 3 are flush with the junction of the first white module 1 and the second white module 2, and the adhesive tape 4 is sealed on the The junction of the filter screen 3 and the first white module 1 and the second white module 2 .

[0034] The difference between the white mold assembly for the liquid metal pouring lost foam casting in the second embodiment and the first embodiment is that the filter screen 3 is improved to be the same as the first white mod...

Abstract

The invention provides a lost foam pattern assembly for molten metal pouring lost foam casting. The lost foam pattern assembly is composed of a plurality of lost foam pattern blocks and filter nets, wherein each filter net is placed between every two adjacent lost foam pattern blocks, and two adjacent lost foam pattern blocks and the filter net between the two adjacent lost foam pattern blocks are pasted together through adhesive tape so as to form a combination portion between the two adjacent lost foam pattern blocks; and the problem that when a plurality of lost foam pattern blocks are connected, adhesives are used, and consequently, cracking happens can be solved. In addition, due to negative-pressure pouring of a lost foam, each filter net can well keep connection with two adjacent lost foam pattern blocks, and cracks cannot appear; and in addition, when a joint of a lost foam pattern is spliced, the adhesives are avoided, the gas-forming amount is reduced, the combination speed is high, and the assembly is affordable.

Description

technical field [0001] The invention belongs to the field of mold casting, and relates to filtering equipment for metal liquid pouring casting, in particular to a white mold component for metal liquid casting lost foam casting. Background technique [0002] Lost foam casting is to combine the foam model with the same size and shape as the casting to form a model cluster. After brushing the refractory coating and drying it, it is buried in dry sand to vibrate the shape, and the negative pressure is poured to make the model vaporize, and the liquid metal occupies the position of the model. , a new casting method that forms a casting after solidification and cooling. [0003] The lost foam casting process includes: 1. Making foam plastic white molds, combining pouring systems, brushing the surface of the gasification mold, spraying special high-temperature resistant paint and drying; 2. Putting the special interlayer sand box on the vibrating table, filling Put the bottom sand...
