[0016] The essential features and advantages of the present invention are further described below with reference to examples, but the present invention is not limited to the examples listed.

[0017] like Figures 1 to 3As shown, a large transformer coil demoulding device of this embodiment includes a positioning component 1 and a driver 2. The positioning component 1 is used to position the mold, and the driver 2 extracts the coil from the mold. The driver 2 can be a hydraulic cylinder. The positioning component 1 and the driver 2 are arranged on a sliding seat 3. The sliding seat 3 is slidably arranged on a base plate 4, so that the sliding seat 3 can slide on the base plate 4. The base plate 4 is connected to an adjustment mechanism 5 for adjusting the position of the base plate 4. The adjustment mechanism 5 includes an adjustment rod 51, a transmission mechanism 52 and a power rod 53. The power rod 53 is connected to the adjustment rod 51 through the transmission mechanism 52. The rotation of the power rod 5 drives the adjustment rod 51 to rotate. The power rod 5 can be driven manually or by an existing power device. The adjustment rod 51 is threadedly connected to the sleeve 54. The sleeve 54 is fixed on the mounting seat 55. One end of the adjustment rod 51 is connected to the base plate 4. By rotating the adjustment rod 51, it can be moved relative to the sleeve 54, thereby driving the base plate 4 to move, so that the positioning component 1 moves. The positioning assembly 1 is vertically arranged, and the positioning assembly 1 includes a fixed ring 11 and a snap ring 12. The fixed ring 11 is fixedly arranged on the sliding seat 3. The snap ring 12 is pivotally connected to the fixed ring 11 at one end, and is connected at the other end by a locking assembly 13. The snap ring 12 can be locked or released by the locking assembly 13. In the above technical solution, when the coil needs to be demoulded, the horizontal position of the positioning assembly 1 is adjusted through the adjustment mechanism 5 so that it is located above the mold, and then the snap ring 12 is opened, and it slides downward through the sliding seat 3. The mold is clamped by the fixed ring 11 and the snap ring 12, and then it is connected to the demoulding head through the driver 2, and the coil is ejected by the driver 2. Through the above technical solution, the positioning assembly can be adjusted to facilitate the correspondence between the driver and the mold position, reduce the difficulty of transportation, and improve the demoulding efficiency.

[0018] In this embodiment, the transmission mechanism 52 includes a first bevel gear 521 and a second bevel gear 522, the first bevel gear 521 and the second bevel gear 522 are meshed, the power rod 53 is connected to the first bevel gear 521, the second bevel gear 522 is sleeved on the outside of the sleeve 54, and the adjustment rod 51 and the power rod 53 are perpendicular to each other. In the above technical solution, the power rod 53 drives the first bevel gear 521 to rotate, which drives the second bevel gear 522 to rotate. The first and second bevel gears are perpendicular to each other, thereby driving the adjustment rod 51 to rotate. The sliding seat 3 is provided with a support plate 31, and the cross-section of the support plate 31 is V-shaped, so that the support plate 31 can be used to lean against the mold when positioning, which is convenient for limiting the mold. The bottom plate 4 is provided with a slide groove 41, and the sliding seat 3 is provided with a roller 31, which is arranged in the slide groove 41, so that the roller 31 can slide in the slide groove to enable the sliding seat 3 to move. The sliding seat 3 is connected to the driving cylinder 6, and the driving cylinder 6 drives the sliding seat 3 to slide. The snap ring 12 is provided with a grip 121, which the user grasps and operates to open or close the snap ring 12. The transmission mechanism 5 is housed in a transmission case 7, which is connected to a bracket 8. The transmission case 7 protects the transmission mechanism 5 and is fixed to a wall or a fixed base via the bracket 8. The locking assembly 13 includes a bolt 131, which is inserted into the connection hole 14 between the fixing ring 11 and the snap ring 12, thereby facilitating the locking or releasing of the snap ring 12.
