As shown in fig. 1 to 3, the splicing die for copper alloy includes a splicing die set 10 and a splicing member 20, the splicing die set 10 includes at least a first die set 11 and a second die set 12, the first die set 11 and the second die set 12 are spliced together, the splicing member 20 is installed between the first die set 11 and the second die set 12, and the splicing member 20 is in close contact with the first die set 11 and the second die set 12.

Splitting the graphite mold into a plurality of splicing modules 10, splicing, wherein connecting the first module 11 and the second module 12 by using a splicing piece 20, if directly splicing the first module 11 and the second module 12, the splicing part can not be in complete contact due to poor matching, during pouring, copper alloy melt easily passes through the splicing part, the splicing part directly flows out of the copper alloy melt, potential safety hazards exist, the first module 11 and the second module 12 of the splicing piece 20 are not in direct contact, the gravity of the compressibility and the second module 12 is realized through the splicing piece, the splicing piece 20 is respectively in close contact with the first module 11 and the second module 12, and the situation that the copper alloy melt flows out of the splicing part is avoided. The graphite mold can appear the regional damage of part after long-term use, need wholly change graphite mold, but in this scheme, set graphite mold to concatenation graphite mold, when some modules appear in the use and damage, only to this module part change can, if first module 11 appears damaging, just the first module 11 of renewal has prolonged graphite mold's life and has reduced the cost of maintaining.

The splice module 10 can include a plurality of modules, such as three, four, or more, as desired. In the present embodiment, two modules are used, namely, a first module 11 and a second module 12.

In this embodiment, the splicing element 20 is made of carbon felt. The carbon felt is mainly made of carbon and is flexible, so that after the second module 12 is put down, the carbon felt is extruded by the gravity of the second module 12 to be slightly deformed, the contact part of the carbon felt and the second module 12 and the contact part of the carbon felt and the first module 11 are abutted together, and the outflow of copper alloy melt can be effectively prevented.

The height of the splice 20 here is 3 mm to 15 mm. Specifically 10 mm in height in this embodiment. The height of the splice 20 is the distance between the first module 11 and the second module 12.

The thermal barrier 1122 may be in close proximity to the graphite body 111 to prevent the graphite body 111 from contacting air. The heat insulation layer 1122 is made of heat insulation cotton, for example, asbestos is used, so that a heat insulation effect can be achieved, overheating of the shape fixing layer 1121 can be avoided, and the phenomenon that the fluidity is deteriorated due to rapid temperature drop of high-temperature liquid fluid to affect the forming of the workpiece can also be prevented. The fixing layer 1121 is made of a metal material, such as steel.

As shown in fig. 3, the covering member 112 is provided as two covering segments, one end of which is hinged and the other end of which is fixedly connected. The arrangement can facilitate demolding of the graphite mold, and the thermal insulation layer 1122 can be tightly pressed on the graphite body 111 by means of fixing and full connection.

As shown in fig. 3 and 4, the graphite body 111 includes two modules 1111, the modules 1111 are spliced with each other to form the graphite body 111, a fastening member is sleeved on the outer side of the graphite body 111, the fastening member includes a strap 113 and a fixing nail body 114, two ends of the strap 113 are close to each other, and the fixing nail body 114 compresses the strap 113. Here, the band 113 is put on two modules 1111, the modules 1111 are fixed, and the band 113 is put on the modules 1111 end to end and then is fixed by the fixing nail body 114.

The copper alloy splicing mould further comprises a heat insulation cap opening 30, and the heat insulation cap opening 30 is installed at the top of the splicing module 10. The part is a pouring gate part of the mold and plays a role in supplementing shrinkage cavities of a poured product body.

There are also a cushion 40 and a bottom plate 50 at the bottom of the splicing module 10, the splicing mold is in contact with the cushion 40, and the cushion 40 is placed on the bottom plate 50.
