[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0017] Specific implementation examples are given below.
[0018] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7This utility model provides a dry-type transformer casting mold that is easy to clean, including a base 1; characterized in that: multiple sets of support rods 11 are fixedly connected to the side wall of the base 1; a support platform 12 is fixedly connected to the side wall of the support rods 11; a placement groove 13 is opened on the side wall of the base 1; a positioning ring block 14 is fixedly connected to the side wall of the placement groove 13; a bearing 15 is rotatably connected to the inner side wall of the positioning ring block 14; a gear shaft 16 is fixedly connected to the side wall of the bearing 15; a first motor 17 is fixedly connected to the side wall of the placement groove 13; a gear rod 18 is provided at the output end of the first motor 17; the gear shaft 16 and the gear rod 18 are meshed; the gear shaft 16 A binding plate 19 is fixedly connected to the side wall; a lower mold 101 is provided on the side wall of the binding plate 19; an electric push rod 102 is fixedly connected to the inner side wall of the support platform 12; a second motor 103 is fixedly connected to the output end of the electric push rod 102; a connecting plate 104 is provided at the output end of the second motor 103; an upper mold 105 is slidably connected to the inner side wall of the connecting plate 104; a left mold 106 and a right mold 107 are placed on the side walls of the lower mold 101 and the upper mold 105; the left mold 106 and the right mold 107 are slidably connected to the lower mold 101 and the upper mold 105; during operation, after the mold has cooled down, the first motor 17 is started to drive the gears. The wheel rod 18 rotates, and through the meshing connection between the gear rod 18 and the gear shaft 16, it can drive the gear shaft 16 to rotate. During the rotation of the gear shaft 16, the bearing 15 improves the smoothness of the rotation of the gear shaft 16. When the gear shaft 16 rotates, it drives the lower mold 101 to rotate through the binding plate 19, thereby driving the left mold 106, right mold 107 and the casting part to be demolded on the lower mold 101 to rotate. At the same time, while the first motor 17 is started to drive the lower mold 101 to rotate, the second motor 103 is started to drive the connecting plate 104 to rotate, thereby driving the upper mold 105 to rotate. By setting the rotation speeds of the first motor 17 and the second motor 103, the lower mold 101 and the upper mold 105 achieve the same rotation speed, thereby synchronously driving the left mold 106, the right mold 107, and the casting to be demolded in the middle from both ends to rotate. During the demolding process, the high-speed rotation of the casting in the mold accelerates the separation of the casting from the mold by utilizing the centrifugal force generated by the rotation. At the same time, after the detached casting is removed, the centrifugal force is enhanced by adjusting the rotation speed, which can forcefully throw out residues such as solidified resin and metal shavings from the mold seams and joints, thus facilitating the cleaning of the mold by the staff.
[0019] Furthermore, such as Figure 5 , Figure 6As shown, the left mold 106 has multiple sets of fixed rotating rod blocks 2 symmetrically fixed to its side wall; the right mold 107 has multiple sets of fixed slot blocks 23 symmetrically fixed to its side wall; the fixed rotating rod block 2 has a rotating handle 21 rotatably connected to its side wall; the rotating handle 21 has a rubber latch block 22 fixed to its side wall; the inner side wall of the fixed slot block 23 has multiple sets of first spring assemblies 24 fixed to its inner wall; the end of the first spring assembly 24 has a rubber block 25 fixed to its end; the inner side wall of the fixed slot block 23 has a rubber block 25 slidably connected to its inner wall; during operation, after connecting the left mold 106 and the right mold 107 to the lower mold 101, the operator rotates the rotating handle 21 towards the middle of the fixed slot block 23 to slide the rotating handle 21 into the middle of the fixed slot block 23, thereby sliding the rubber latch block 22 into the fixed slot. The middle part of block 23 restricts and fixes the rubber clamping block 22. During the process of the rubber clamping block 22 sliding into the middle of the fixed groove block 23, the first spring assembly 24 will cause the rubber block 25 to slide into the inner wall of the fixed groove block 23. When the rubber clamping block 22 slides into the middle of the fixed groove block 23, the first spring assembly 24 generates a rebound force to push the rubber block 25, and the rubber block 25 squeezes the protrusion of the rotating handle 21, thereby completing the clamping fixation, thereby improving the connection stability of the left mold 106 and the right mold 107. This design, by setting multiple sets of clamping fixing devices on the side walls of the left and right molds, can clamp and fix the connection at different heights of the left and right molds, thereby improving the connection stability between the left and right molds, and thus improving the connection stability effect when the mold rotates.
[0020] Furthermore, such as Figure 7 As shown, the connecting plate 104 has symmetrically opened sliding grooves 3 on its sidewalls; the upper mold 105 has symmetrically opened fixed sliding grooves 31 on its sidewalls; sliding rods 32 are slidably connected to the sidewalls of the sliding grooves 3 and the fixed sliding grooves 31; a limiting ring 33 is fixedly connected to the sidewall of the sliding rod 32; a second spring assembly 34 is fixedly connected to the sidewall of the limiting ring 33; the second spring assembly 34 is sleeved and connected to the sidewall of the sliding rod 32; the second spring assembly 34 is fixedly connected to the sidewall of the sliding groove 3; during operation, the sliding rods 32 on both sides can slide out of the fixed sliding grooves 31 by pulling them outward, and this process will put pressure on the second spring assembly 34. Compression releases the fixing effect on the fixed groove 31, thereby detaching the upper mold 105 from the groove opening 3 for disassembly. Simultaneously, when connecting and fixing the upper mold 105, after placing it inside the groove opening 3, releasing the pull on the slide rod 32 allows the slide rod 32 to slide inward through the rebound force of the second spring assembly 34, and slide into the fixed groove 31, thereby fixing the upper mold 105. This design, through the set quick disassembly connection structure, enables the quick installation and disassembly of the upper mold, thereby improving the flexibility of installation and disassembly.
[0021] Furthermore, such as Figure 5As shown, both the left mold 106 and the right mold 107 have filling grooves 4 on their side walls; strong magnet blocks 41 are fixed to the side walls of the filling grooves 4; during operation, the strong magnet blocks 41 set on the side walls of the left mold 106 and the right mold 107 can enhance the connection stability between the left and right molds by setting the magnetic attraction effect of the two strong magnet blocks 41 when they are spliced.
[0022] Furthermore, such as Figure 5 As shown, the right mold 107 has a left strong magnetic half-circle 5 magnetically connected to its side wall; the left mold 106 has a right strong magnetic half-circle 51 magnetically connected to its side wall; the right strong magnetic half-circle 51 is slidably connected to the inner side wall of the left strong magnetic half-circle 5; the left strong magnetic half-circle 5 and the right strong magnetic half-circle 51 are magnetically connected; during operation, after the mold is assembled, the right strong magnetic half-circle 51 is manipulated to connect with the left strong magnetic half-circle 5 through a slot, thus achieving a magnetic connection between the left and right strong magnetic half-circles 5 and 51. The connection between the left and right molds 106 and 107 is constrained by the opening of the left and right strong magnetic half-circles 5 and 51. This design, through the strong magnetic opening constraint device, can improve the stability of the assembly of the left and right molds.
[0023] Furthermore, such as Figure 6 As shown, a rubber sleeve 6 is fixedly connected to the middle of the rotating handle 21. During operation, when the operator rotates the rotating handle 21, the rubber sleeve 6 can enhance the friction. This design can improve the gripping force of the operator when operating the rotating handle 21 by enhancing the friction.
[0024] Working principle: After the mold cools down, the first motor 17 is started to drive the gear rod 18 to rotate. Through the meshing connection between the gear rod 18 and the gear shaft 16, the gear shaft 16 can be driven to rotate. During the rotation of the gear shaft 16, the bearing 15 improves the smoothness of the rotation. As the gear shaft 16 rotates, the binding plate 19 drives the lower mold 101 to rotate, thereby causing the left mold 106, right mold 107, and the casting to be demolded on the lower mold 101 to rotate. Simultaneously, while the first motor 17 drives the lower mold 101 to rotate, the second motor 103 is started to drive the connecting plate 104 to rotate, thereby causing the upper mold 105 to rotate. The rotational speeds of the first motor 17 and the second motor 103 are set so that the lower mold 101 and the upper mold 105 reach the same rotational speed. This allows the left mold 106, the right mold 107, and the casting to be demolded to rotate synchronously from both ends. After connecting the left mold 106 and the right mold 107 to the lower mold 101, the operator rotates the handle 21 towards the center of the fixed slot block 23, sliding the handle 21 into the center of the fixed slot block 23. This allows the rubber locking block 22 to slide into the center of the fixed slot block 23, thus securing and fixing the rubber locking block 22. During the process of the rubber locking block 22 sliding into the center of the fixed slot block 23, the first spring assembly 24 causes the rubber block 25 to slide into the fixed slot block 23. Inside the inner wall of the slot block 23, when the rubber latch block 22 slides into the middle of the fixed slot block 23, the first spring assembly 24 generates a rebound force to push the rubber block 25, and the rubber block 25 squeezes the protrusion of the rotating handle 21, thereby completing the latch fixation, thus improving the connection stability of the left mold 106 and the right mold 107. By pulling the sliding rods 32 on both sides outward, they can slide out of the fixed slide groove 31. This process will compress the second spring assembly 34, thereby releasing the fixing restriction effect on the fixed slide groove 31, so that the upper mold 105 can be disconnected from the slide groove 3 for disassembly. At the same time, when connecting and fixing the upper mold 105, after placing it inside the slide groove 3, the pull on the sliding rod 32 is released, and the upper mold 105 can be disassembled. The rebound force of the second spring assembly 34 can drive the slide rod 32 to slide inward and into the fixed slide groove 31, thereby fixing the upper mold 105. By setting strong magnet blocks 41 on the side walls of the left mold 106 and the right mold 107, when they are spliced, the magnetic attraction effect of the two strong magnet blocks 41 is set. After the mold is spliced, by operating the right strong magnetic half-circle 51 to connect it with the left strong magnetic half-circle 5, the magnetic attraction connection between the left strong magnetic half-circle 5 and the right strong magnetic half-circle 51 can be realized. The ring opening of the left strong magnetic half-circle 5 and the right strong magnetic half-circle 51 restricts the ring opening connection between the left mold 106 and the right mold 107. When the operator rotates the rotating handle 21, the friction can be enhanced by the rubber sleeve 6.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
