Description

Technical Field

[0001] This application relates to the field of dry-type transformer manufacturing technology, and more specifically, to a dry-type transformer casting mold. Background Technology

[0002] Dry-type transformers are widely used in high-rise buildings, subways, nuclear power plants, and other locations due to their advantages such as fire resistance, moisture resistance, and ease of maintenance. Their core component, the winding, is typically molded using epoxy resin casting, and the structural rationality of the casting mold directly affects the product's molding quality, production efficiency, and manufacturing cost.

[0003] In related technologies, for example, the prior art patent with publication number CN214753389U provides a dry-type transformer casting mold, which is provided with a device body, guide columns, casting outer mold and sealing upper end plate. The device body has a main directional threaded rod running through both the front and rear sides. The outer wall of the casting outer mold is clamped and fixed by the guide columns and limiting threaded rods on the top surface of the device body. The sealing upper end plate connected to the top of the limiting threaded rod is used for sealing and covering, so as to achieve the effect of vacuum casting.

[0004] Although the existing technical solution described above solves the problems in the background technology, the casting mold can only cast transformers of a fixed height because the height of the inner and outer molds is fixed. When the height of the transformer is different, a new casting mold must be made, which increases the production cost.

[0005] In view of this, we propose a dry-type transformer casting mold. Utility Model Content

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1 to 5 This application discloses a dry-type transformer casting mold, which includes a base plate 1; an inner mold 2 and an outer mold 3 are provided on the base plate 1; a cavity 4 is formed between the inner mold 2 and the outer mold 3; an adjustment mechanism is hinged to one side of the outer mold 3; a panel template 21 is provided on the other side of the outer mold 3; the panel template 21 is fixedly connected to the outer mold 3 by fixing bolts.

[0026] By setting up an inner mold 2, an outer mold 3, a cavity 4, an adjustment mechanism, and a panel template 21, the inner mold 2 and the outer mold 3 together form the cavity 4 during use. Then, the adjustment mechanism changes the position of the pressure plate 10 in the cavity 4, thereby changing the volume of the cavity 4, so that transformers of different heights and sizes can be manufactured. The panel template 21 is fixed to the outer mold 3 by fixing bolts, which can seal and fix the outer mold 3.

[0027] Reference Figure 4 and Figure 5 The adjusting mechanism includes a rotating sleeve 5; the rotating sleeve 5 is fixedly mounted on the side wall of the outer mold 3; a rotating rod 6 is rotatably mounted in the rotating sleeve 5; a fixed rod 7 is fixedly mounted on the rotating rod 6; a cross 8 is fixedly mounted on the fixed rod 7; the width of the cross 8 is greater than the width of the cavity 4; a connecting rod 9 slides through the cross 8; a pressure plate 10 is fixedly mounted at the lower end of the connecting rod 9; a moving plate 11 is fixedly mounted at the upper end of the connecting rod 9; a lead screw 12 is rotatably mounted on the cross 8; the other end of the lead screw 12 extends to the outside of the moving plate 11; the lead screw 12 and the moving plate 11 are threadedly rotatably connected.

[0028] By setting up a rotating sleeve 5, a rotating rod 6, a fixed rod 7, a cross 8, a connecting rod 9, a pressure plate 10, a moving plate 11, and a lead screw 12, in use, the rotating sleeve 5 is first fixedly set on the outer mold 3, so that the rotating rod 6 can rotate in the rotating sleeve 5. Then, the cross 8 is connected to the rotating rod 6 through the fixed rod 7, so that the cross 8 can rotate. Then, the cross 8 is first set on the cavity 4, and the cross 8 is fixed by the inner mold 2 and the outer mold 3. Then, according to the required transformer height, the lead screw 12 is rotated, so that the lead screw 12 drives the moving plate 11 to move, which in turn drives the connecting rod 9 and the pressure plate 10 to move, so that the pressure plate 10 compresses the cavity 4 to a suitable volume. When demolding, the lead screw 12 is rotated so that the pressure plate 10 is close to the cross 8, and then the cross 8 is rotated to open the cavity 4, which facilitates demolding.

[0029] Reference Figure 1 A telescopic tube 13 is fixedly installed on the pressure plate 10; one end of the telescopic tube 13 extends into the cavity 4; the other end of the telescopic tube 13 extends to the outside of the moving plate 11.

[0030] By setting up the telescopic tube 13, when the pressure plate 10 moves up and down, the telescopic tube 13 can extend and retract, and then the raw material can be injected into the cavity 4 through the telescopic tube 13.

[0031] Reference Figure 1 An observation window 14 is provided on the outer mold 3; the observation window 14 is made of transparent material; and scale lines 15 are provided on the side wall of the observation window 14.

[0032] By setting up the observation window 14 and the scale line 15, the observation window 14 can be used to observe the position of the pressure plate 10 in the cavity 4 during use. Then, combined with the scale line 15, it is convenient for the staff to observe whether the volume of the cavity 4 is appropriate.

[0033] Reference Figure 5 An installation groove 16 is provided on the side wall of the pressure plate 10; a sealing gasket 17 is fixedly installed in the installation groove 16.

[0034] By setting the mounting groove 16 and the sealing gasket 17, the mounting groove 16 can install the sealing gasket 17 during use, and then the sealing gasket 17 contacts the inner wall of the outer mold 3 to seal the cavity 4.

[0035] Reference Figure 1 A handle 18 is fixedly provided at one end of the lead screw 12; an anti-slip groove 19 is provided on the side wall of the handle 18; the number of anti-slip grooves 19 is several and evenly distributed.

[0036] By setting the handle 18 and the anti-slip groove 19, the handle 18 can provide a point of leverage for the operator during use, making it easier for the operator to turn the screw 12. The anti-slip groove 19 can increase the friction between the operator and the handle 18, preventing the operator from slipping.

[0037] Reference Figure 1 A handle 20 is fixedly installed on the movable plate 11.

[0038] By providing a handle 20, the operator can gain leverage during use, making it easier for them to rotate the movable plate 11 and the cross 8.

[0039] In summary, the dry-type transformer casting mold disclosed in this application, when in use, firstly, the inner mold 2 and the outer mold 3 together form the cavity 4. The rotating sleeve 5 is fixedly mounted on the outer mold 3, allowing the rotating rod 6 to rotate within the rotating sleeve 5. Then, the cross 8 is connected to the rotating rod 6 via the fixing rod 7, allowing the cross 8 to rotate. The cross 8 is then placed on the cavity 4 and fixed by the inner mold 2 and the outer mold 3. Next, according to the required transformer height, the lead screw 12 is rotated, causing the lead screw 12 to move the moving plate 11, which in turn moves the connecting rod 9 and the pressure plate 10, compressing the cavity 4 to a suitable volume. When demolding, the lead screw 12 is rotated to bring the pressure plate 10 close to the cross 8, and then the cross 8 is rotated to open the mold. The mold cavity 4 is designed for easy demolding. When the pressure plate 10 moves up and down, the telescopic tube 13 can extend and retract, allowing raw materials to be injected into the mold cavity 4. The observation window 14 allows observation of the position of the pressure plate 10 in the mold cavity 4. Combined with the scale line 15, it allows workers to easily observe whether the volume of the mold cavity 4 is appropriate. The mounting groove 16 allows the installation of the sealing gasket 17. The sealing gasket 17 then contacts the inner wall of the outer mold 3, sealing the mold cavity 4. The handle 18 provides a point of leverage for workers to easily rotate the screw 12. The anti-slip groove 19 increases the friction between the worker and the handle 18, preventing slippage. Finally, the lifting handle 20 provides a point of leverage for workers to easily rotate the moving plate 11 and the cross 8.
