The vertical surfaces of the second forming plates 2 are perpendicularly connected to the vertical surfaces of the first forming plates 1. The first forming plates 1 are connected to the second forming plates 2 by multiple connecting bolts 4, and the connecting bolts 4 horizontally penetrate the second forming plates 2. The bottom surfaces of the first forming plates 1 and the second forming plates 2 are detachably fixed to the base plate 3 by locking bolts 5, forming a cuboid casting cavity that can shape the bismuth ingot.

The connecting bolts 4 pass through the through holes 101 to connect the first forming plate 1 and the second forming plate 2, and are fastened by connecting nuts, which facilitates disassembly and assembly.

[0023] The first forming plate 1, the second forming plate 2, and the base plate 3 are vertically fixedly connected. Multiple threaded blind holes 102 are equidistantly formed on the bottom surfaces of the first forming plate 1 and the second forming plate 2. Stepped countersunk holes 301 are equidistantly formed on the base plate 3. The number of threaded blind holes 102 and countersunk holes 301 are the same, and their center positions correspond one-to-one. The base plate 3 is provided with multiple locking bolts 5 corresponding to the countersunk holes 301. The locking bolts 5 pass through the countersunk holes 301 and are locked to the blind holes 102, facilitating disassembly and ensuring a secure connection.

[0024] The gaps at the joints of the first molding plate 1, the second molding plate 2, and the base plate 3 are filled with high-temperature resistant adhesive, which can effectively prevent bismuth liquid leakage and ensure the sealing and stability of the casting process.

[0025] In this embodiment, an ingot with dimensions of 330×450×32mm is used for casting, with a theoretical single weight of 46.5kg. The specifications and quantities of each component in the mold are as follows:

[0034] The installation steps of the pouring mold for large-size bismuth ingots are as follows:

[0035] First, apply high-temperature resistant glue between the stepped countersunk hole 301 on the bottom surface of the bottom plate 3 and the first forming plate 1 and the second forming plate 2, then place one first forming plate 1 on the corresponding position of the bottom plate 3, ensure that the five threaded blind holes 102 of the first forming plate 1 correspond to the countersunk holes 301 of the bottom plate 3, after placing the first forming plate 1, insert the locking bolt 5 from the countersunk part of the countersunk hole 301 of the bottom plate 3 (i.e. the bottom of the bottom plate 3), until the locking nut is screwed into the blind hole 102 of the first forming plate 1, then continue to tighten the locking nut, so as to fix the first forming plate 1; Next, place one second forming plate 2 on the corresponding position of the bottom plate 3, ensure that the one threaded blind hole 102 of the second forming plate 2 corresponds to the stepped countersunk hole 301 of the bottom plate 3, after placing the second forming plate 2, insert the locking bolt 5 from the countersunk part of the stepped countersunk hole 301 of the bottom plate 3 (i.e. the bottom of the bottom plate 3), until the locking nut is screwed into the threaded blind hole 102 of the second forming plate 2, then continue to tighten the locking nut, so as to fix the second forming plate 2; Next, install and fix the second first forming plate 1 and the bottom plate 3 in turn, the steps are the same as before.

[0036] At this time, the two fixed first forming plates 1, one second forming plate 2 are tightened and fixed one by one through the connecting bolt 4, the connecting bolt with gasket and nut. Then install and fix the second second forming plate 2 and the bottom plate 3, the steps are the same as before.

[0037] Finally, check that the first forming plate 1 and the second forming plate 2 are tightened and fixed by the connecting bolts 4, and verify the wall thickness of 32mm, and adjust the tightness of the connection as appropriate.

[0038] After the first molding plate 1, the second molding plate 2, and the base plate 3 are fully connected and fixed, in order to ensure that no leakage occurs during pouring, high-temperature resistant adhesive is applied to the vertical and horizontal joints formed by all contact surfaces of the first molding plate 1, the second molding plate 2, and the base plate 3.

[0039] After the bismuth ingot is poured, remove the connecting bolt 4, the matching washer and nut for the connecting bolt, and the locking bolt 5 in sequence. After removal, gently tap the mold steel with a wooden hammer, and the bismuth ingot and the mold steel can be easily separated, completing the disassembly process.
