[0002] In the manufacturing process of power equipment, vacuum-impregnated sheets, as an important insulating material, have high requirements for their mechanical strength and electrical performance to ensure the quality of power equipment or products made from them and to meet their performance requirements. In the specific processing, the demolding process of the impregnated sheets usually requires two operators. One operator holds the mat, while the other uses a solid steel bar weighing over 20 kilograms to strike the sheet and demold it. This demolding process is time-consuming, generally taking 10-15 minutes, and the operators need to frequently strike the sheet with heavy objects, which can easily cause shoulder and back muscle injuries. Furthermore, the striking process can easily lead to cracks and chips in the impregnated sheets, making it difficult to guarantee the quality of the product. Utility Model Content

The pressure positioning components include a jack, a support guide rail, a guide post, a baffle, a support plate, a clamp, and a pad. The jack is set on the pad. The baffle and the support plate are respectively vertically fixed to the demolding body. The guide post passes through the baffle, the support plate, and the bottom of the jack and is fixed. The support guide rail is sleeved on the outer wall of the guide post. The clamp is welded to the protruding part on the side of the jack. In use, the pressure positioning components press down on the dipped plate, and an electric wrench is inserted into the clamp and rotated to move the demolding components upward until the mold is completely detached from the dipped plate.

[0006] Furthermore, the demolding body is a one-piece molded structure.

[0007] Furthermore, the lower end of the demolding body is set as an "L" hook, and the horizontal dimension of the "L" hook is less than or equal to the thickness of the mold.

[0008] Furthermore, two suspension blocks are welded to the upper end of the demolding body. The suspension blocks can move horizontally along the guide rail to meet the demolding needs of impregnated sheets of different sizes.

[0009] Furthermore, both the vertical and horizontal pads are bolted to the demolding body, and both the vertical and horizontal pads are made of insulating bakelite board.

[0014] Furthermore, the handles are made of rubber and are fitted onto both ends of the guide rail.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects:

[0016] A demolding device for dipped sheets includes a guide rail assembly, two demolding components, and two pressure positioning components. The guide rail assembly includes handles, hanging rings, and guide rails. Handles are provided at both ends of the guide rails for easy use and transfer of the demolding device by operators. The hanging rings are fixed in the middle of the guide rails and can be used for hanging and storage after use, saving space. Each demolding component includes a suspension block, a demolding body, a vertical pad, and a horizontal pad. The suspension block is fixed to the upper end of the demolding body, and the demolding body is fitted onto the guide rail through the suspension block. Under the condition of meeting mechanical strength requirements, the distance between the two demolding components can be easily adjusted to achieve demolding of dipped sheets of different specifications and sizes. Vertical and horizontal pads are fixed to the inner side of the lower end of the demolding body, effectively protecting the impregnated sheet after demolding. The pressure positioning assembly includes a jack, support rails, guide pillars, baffles, support plates, a retainer, and a pad. The jack is placed on the pad, and the baffles and support plates are vertically fixed to the demolding body. The guide pillars pass through the baffles, support plates, and the bottom of the jack, ensuring that the support rails fit over the outer wall of the guide pillars and preventing shaking during demolding. The retainer is fixed to the protruding part on the side of the jack. In use, the bottom of the jack presses against the upper surface of the impregnated sheet, and the electric wrench is screwed into the retainer to rotate, causing the demolding assembly to move vertically upward. At the same time, the lower end of the demolding assembly hooks onto the mold of the impregnated sheet and moves vertically upward until the mold is completely detached from the impregnated sheet, thus achieving demolding of the impregnated sheet.

[0021] Furthermore, the guide rail is made of 30mm*30mm*3mm square steel, which meets the mechanical strength requirements of the guide rail and is not easily deformed under stress.

[0022] Furthermore, the jack is a rotary jack, with a retainer at the end of the manual rotary handle. An electric wrench is inserted into the retainer and rotated, pressing the bottom of the jack against the upper surface of the dipped plate. At the same time, the demolding component hooks the mold of the dipped plate and moves it vertically upward, thereby demolding the dipped plate.

[0023] Furthermore, the card holder has an internal hexagonal threaded hole, which makes it easy for an electric wrench to be screwed into the card holder and fixed.

[0024] Furthermore, the pad is bolted to the bottom of the jack. The pad is made of a non-metallic soft material, which cushions the pressure of the jack on the upper surface of the dipped plate during demolding, thus protecting the upper surface of the dipped plate from damage.

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings:

[0032] This utility model discloses a demolding device for impregnated sheets, including a guide rail assembly, two demolding components, and two pressure positioning components. The guide rail assembly includes a handle 1, a hanging ring 2, and a guide rail 3. The handle 1 is provided at both ends of the guide rail 3, and the hanging ring 2 is fixed in the middle of the guide rail 3. The demolding components include a suspension block 4, a demolding body 5, a vertical pad 7, and a horizontal pad 8. The suspension block 4 is fixed to the upper end of the demolding body 5, and the demolding body 5 is fitted onto the guide rail 3 through the suspension block 4. The vertical pad 7 and the horizontal pad 8 are respectively fixed to the inner side of the lower end of the demolding body 5. The pressure positioning components include a jack 9. The system includes a support rail 6, a guide post 10, a baffle 11, a support plate 12, a clamping seat 13, and a pad 14. The jack 9 is mounted on the pad 14. The baffle 11 and the support plate 12 are vertically fixed to the demolding body 5. The guide post 10 passes through the baffle 11, the support plate 12, and the bottom of the jack 9 and is fixed. The support rail 6 is fitted onto the outer wall of the guide post 10. The clamping seat 13 is welded to the protruding part on the side of the jack 9. In use, the pressure positioning component presses down on the dipped plate 15, and the electric wrench is inserted into the clamping seat 13 and rotated to move the demolding component upward until the mold 16 is completely separated from the dipped plate.

[0033] Specifically, the demolding body 5 is molded as a single piece.

[0034] Specifically, the lower end of the demolding body 5 is set as an "L" hook, and the horizontal dimension of the "L" hook is less than or equal to the thickness of the mold 16.

[0035] Specifically, two suspension blocks 4 are welded to the upper end of the demolding body 5. The suspension blocks 4 can move horizontally along the guide rail 3 to meet the demolding of impregnated plates 15 of different sizes.

[0036] More preferably, both the vertical pad 7 and the horizontal pad 8 are bolted to the demolding body 5, and both the vertical pad 7 and the horizontal pad 8 are made of insulating bakelite board.

[0037] More preferably, the guide rail 3 is made of square steel with a diameter of 30mm*30mm*3mm.

[0038] Specifically, the jack 9 is a rotary jack, and the end of the manual rotary handle of the rotary jack is provided with a retainer 13, and the electric wrench is inserted into the retainer 13 to rotate.

[0039] Specifically, the seat 13 has an internal hexagonal threaded hole.

[0040] Specifically, the pad 14 is bolted to the bottom of the jack 9, and the pad 14 is made of non-metallic soft material.

[0041] Even better, the handle 1 is made of rubber and is fitted onto both ends of the guide rail 3.

[0042] As attached Figures 1-3 As shown, the impregnated sheet demolding device includes a guide rail assembly, two demolding assemblies, and two pressure positioning assemblies.

[0043] The guide rail assembly includes a handle 1, a hanging ring 2, and a guide rail 3. The handle 1 is embedded in both ends of the guide rail 3, making it convenient for operators to use and move the device. The guide rail is cut from a 30*30*3 square steel. The hanging ring 2 is welded to the middle of the guide rail 3, allowing the device to be easily hung up when not in use, saving space.

[0044] Each demolding assembly includes two suspension blocks 4, a demolding body 5, a vertical pad 7, and a horizontal pad 8. The suspension blocks 4 are welded to the upper end of the demolding body 5. To accommodate demolding of different sizes of impregnated sheets 15 within limited manufacturing costs, the suspension blocks 4 can move the entire demolding assembly and pressure positioning assembly left and right on the guide rail 3, adjusting the distance between the demolding components. For structural stability and reliability, the lower end of the demolding body 5 is designed with an "L"-shaped hook, which is simple in structure, provides strong rigid support, and better hooks the bottom and outer side of the mold 16 during demolding, preventing wobbling and ensuring stable demolding in the vertical direction. Each demolding body 5 is mounted on the guide rail 3 via the suspension blocks 4. During demolding, to prevent scratching or damaging the surface of the mold 16, a vertical pad 7 and a horizontal pad 8 are bolted or bonded to the inner side of the "L"-shaped hook at the bottom of the demolding body 5. Both the vertical pad 7 and the horizontal pad 8 are made of insulating bakelite board.

[0045] Each pressure positioning assembly includes a jack 9, six support rails 6, guide pillars 10, a baffle 11, a support plate 12, a retainer 13, and a pad 14. The jack is a modified 2-ton double-section mechanical gear tower jack. The rotating part of the original jack handle has been cut off, and an internal hexagonal retainer 13 has been welded to the demolding assembly. This structure, which replaces the manual rotation of the jack with an electric wrench that engages with the retainer 13, greatly reduces the labor intensity of the operator compared to the previous method of demolding by striking the mold 16 with a solid iron block. In order to keep the bottom of the jack 9 pressing against the upper surface of the dipped plate 15 during the demolding process, and to prevent excessive pressure on the bottom of the jack 9 from damaging or scratching the dipped plate 16 and affecting the demolding quality, a pad 14 made of insulating bakelite board is bolted to the bottom of the jack 9. To prevent force deviation during demolding, four guide pillars 10 are added to the four corners of the jack 9. The lower ends of the guide pillars 10 are threaded and installed into four threaded holes at the bottom of the jack 9. The guide pillars 10 extend through the baffle 11, support plate 12, jack 9, and pad 14. To ensure that the vertical force does not deviate during demolding, four support rails 6 are welded between the baffle 11 and support plate 12. The support rails 6 are made of carbon steel and are cut from steel pipes with an outer diameter of 16mm, an inner diameter of 12.5mm, and a length of 90mm. The upper baffle 11 of the jack 9 is used to fix the jack 9. When the stroke of jack 9 is shortened to its shortest length, guide post 10 and the top of jack 9 are pushed upward together until the top of jack 9 is close to baffle 11, and then spot welded to form a whole. The upper surface of baffle 11 and demolding body 5 are firmly welded together around the perimeter, and the upper surface of support plate 12 is also firmly welded to demolding body 5. At this time, the demolding device for impregnated plate 15 is formed by inserting two pairs of hanging rings 2 into guide rail 3.

[0046] The specific steps are as follows:

[0047] (1) The operator takes the demolding device to the site of use;

[0048] (2) Secure the two demolding components of the demolding device to the bottom of the mold 16;

[0049] (3) The operator aligns the electric wrench with the card seat 13, starts the electric wrench, and moves the demolding component upward until the jack 9 presses down on the impregnation plate 15 and loosens it;

[0050] (4) The above operations can be performed in different areas.

[0051] The basic principle of this impregnated sheet demolding device is to demold through the interaction of forces. First, the operator places the demolding device on the mold 16 and adjusts the distance between the two demolding components according to the different sizes of impregnated sheets. Then, the lower L-shaped hook of the demolding body 5 hooks onto the frame of the mold 16. The operator then inserts the Allen wrench into the holder 13 and starts the electric wrench. After the electric wrench rotates, the jack 9 lifts the guide rail assembly and the demolding assembly upward. At the same time, the jack 9 applies a vertical downward force to the impregnated sheet 15. The interaction of forces causes the mold 16 and the impregnated sheet 15 to move relative to each other until the impregnated sheet 15 is completely demolded.
