[0025] Example

[0026] like Figure 1-3 As shown, this embodiment includes a lower mold body 10, an upper mold body 20 arranged on the lower mold body 10, and a left upper mold body 21 and a right upper mold body 22 are provided on both sides of the upper mold body 20. The left upper mold body 21 and the right upper mold body 22 are fixedly connected to the upper mold body 20 through an upper connecting rod 23; in this embodiment, three stepped countersunk holes and two half-side holes are drilled on the upper left mold body 21 and the upper right mold body 22; among them, the three stepped countersunk holes are fixedly connected to the upper connecting rod 23, and the two half-side holes are connected to the upper mold of the casting machine;

[0027] A left lower template 11 and a right lower template 12 are provided on both sides of the lower mold body 10. The left lower template 11 and the right lower template 12 are fixedly connected to the lower mold body 10 through a lower connecting rod 13. In this embodiment, three stepped countersunk holes and two half-side holes are drilled on the left lower template 11 and the right lower template 12. Among them, the three stepped countersunk holes are fixedly connected to the lower connecting rod 13, and the two half-side holes are connected to the lower mold of the casting machine.

[0028] Thus, the lower mold body 10 and the upper mold body 20 are controlled to be pressed against or separated from each other by the operation of the casting machine.

[0029] A left connecting plate cavity 30 and a right connecting plate cavity 40 are formed between the lower mold body 10 and the upper mold body 20; that is, the left connecting plate cavity 30 and the right connecting plate cavity 40 are formed when the lower mold body 10 and the upper mold body 20 are pressed against each other, and a left casting port 31 and a right casting port 41 communicating with the left connecting plate cavity 30 and the right connecting plate cavity 40 are opened on one side of the lower mold body 10 and the upper mold body 20, and a ladle 50 is provided on the lower mold body 10, and the left casting port 31 and the right casting port 41 are both communicated with the ladle 50; thus, by rotating the angle of the lower mold body 10 and the upper mold body 20 by the casting machine, and by pouring the casting material into the ladle 50, the casting material in the ladle 50 enters the left connecting plate cavity 30 and the right connecting plate cavity 40 along the left casting port 31 and the right casting port 41 respectively for casting, and then waits for cooling;

[0030] A plurality of longitudinal through holes 28 are provided on the upper mold body 20, and the plurality of longitudinal through holes 28 are used to place heating tubes; a plurality of transverse through holes 18 are provided on the lower mold body 10, and the plurality of transverse through holes 18 are used to place heating tubes; thus, according to needs, the heating tubes are placed in the plurality of longitudinal through holes 28 and the plurality of transverse through holes 18 to heat the left connecting plate and the right connecting plate during casting to meet quality requirements.

[0031] An upper ejector plate 24 is provided above the upper mold body 20 and below between the upper left mold plate 21 and the upper right mold plate 22.

The plurality of lower through holes 17 are respectively located in the left connecting plate cavity 30 and the right connecting plate cavity 40.

[0035] Thus, when the left connecting plate and the right connecting plate need to be taken out of the casting mold, when the left connecting plate and the right connecting plate are adhered to the lower mold body 10, the lower ejector plate 14 is pressed by the lower ejector rods in the casting machine, and the lower ejector plate 14 rises, so that the plurality of lower ejector rods 16 pass through the plurality of lower through holes 17 and squeeze the left connecting plate and the right connecting plate, so that the left connecting plate and the right connecting plate are separated from the lower mold body 10, thereby realizing the unloading;

[0036] In this embodiment, a plurality of lower reset rods 16-1 are connected to the lower mold body 10 on the side of the lower ejector rod fixing plate 15, and a plurality of lower reset through holes for the plurality of lower reset rods 16-1 to pass through are opened on the lower mold body 10; in this embodiment, the lower reset rods 16-1 are fixedly connected to the lower ejector rod fixing plate 15 by lower reset springs; thus, when the plurality of lower ejector rods 16 pass through the plurality of lower through holes 17 and squeeze the left connecting plate and the right connecting plate so that the left connecting plate and the right connecting plate are separated from the lower mold body 10 and the material is discharged, the plurality of lower reset rods 16-1 are reset by elastic force, so that the plurality of lower ejector rods 16 return to the plurality of reset lower through holes 17, thereby not affecting the casting of the casting mold;

[0037] In addition, the lower mold body 10 is a structure with raised sides and a groove in the middle, and the upper mold body 20 is a structure with a raised middle. Locking bolts 60 are provided on both sides of the lower mold body 10, and threaded holes matching the locking bolts 60 are provided on both sides of the upper mold body 20; thus, the lower mold body 10 and the upper mold body 20 can be further fixed by the locking bolts 60.
