A motor 30 is fixedly connected to the outer wall of the base 1, and the threaded rod 29 is fixedly connected to the driving shaft of the motor 30. The motor 30 drives the threaded rod 29 to rotate, and because the slide plate 28 is provided with a threaded hole to match the threaded rod 29, and under the limiting effect of the inner wall of the sliding channel 27, the threaded rod 29 drives the two square plates 2 to move toward or away from each other through the slide plate 28.

[0037] The top of the square plate 2 is provided with a mold 3, and an arc groove 34 is opened on the top of the square plate 2. The two arc grooves 34 are connected and matched, and an arc block 35 is slidably arranged inside the arc groove 34, and the arc block 35 is fixedly connected to the bottom end of the corresponding mold 3. When the two square plates 2 are close to each other, the two arc grooves 34 are connected and form an annular structure, and the two molds 3 can perform annular movement; and there is a certain damping feeling between the arc block 35 and the arc groove 34, and when subjected to external force, it can rotate to avoid arbitrary rotation.

[0038] The mold 3 is semi-cylindrical, and the concave surfaces of the two molds 3 are close to each other. The flange 4 used to form the outline of the insulator is fixedly connected to the concave of the mold 3. The flange 4 is provided in plurality and the plurality of flanges 4 are evenly distributed, thereby forming a space for extruding the suspension porcelain insulator, and anti-sticking treatment can be performed on the mold 3 and the flange 4, such as spraying anti-sticking material.

[0040] A support box 20 is arranged between the two molds 3. The support box 20 is fixedly connected to the base 1. The top of the support box 20 is connected to a threaded barrel 21.

[0042] Specifically, the cap 22 is butted against the threaded barrel 21 , and the insulator blank is placed at the center of the support box 20 .

[0043] The motor 30 is started to drive the threaded rod 29 to rotate. Since the slide plate 28 is provided with a threaded hole that matches the threaded rod 29 and under the limiting effect of the inner wall of the sliding channel 27, the threaded rod 29 drives the two molds 3 to move toward each other and extrude the insulator blank through the slide plate 28 and the square plate 2.

[0044] At the same time, the second electric push rod 32 pushes the lifting plate 33 downward to fit closely with the insulator blank, and the insulator blank is pressed and molded with the cooperation of the flange 4.

[0045] Then, the electric heating wire is started to heat and form the insulator blank.

[0046] Considering that water vapor is easily generated during the heating process and it is difficult to discharge the water vapor, which will affect the molding efficiency, a through slot 5 is provided through the mold 3, and a plurality of through slots 5 are provided, and the plurality of through slots 5 are staggered with the plurality of flanges 4. A slider 6 for assisting demoulding is provided inside the through slot 5, and the slider 6 is in an arc shape. An inner cavity 12 is provided inside the wall of the mold 3, and air holes 7 for sucking water vapor are provided at both the upper and lower ends of the through slot 5. When the slider 6 is completely located inside the through slot 5, the air hole 7 can be blocked.

[0047] In order to achieve the connection between the two inner cavities 12, a limited position connection component is arranged between the two molds 3, and the limited position connection component includes a socket 16 and a plug 17. The socket 16 is provided on one of the molds 3, and the socket 16 is connected with the corresponding inner cavity 12. The plug 17 is fixed on the other mold 3, and the plug 17 is connected with the corresponding inner cavity 12, and the plug 17 cooperates with the socket 16. The limited position connection component can be arranged in two groups, which can be adjusted according to the specific usage.

[0048] In order to facilitate the operator to control the rotation of the two molds 3 at the same time, a fixed component is arranged between the two molds 3, and the fixed component includes a first magnet 18 and a second magnet 19. The first magnet 18 is fixedly embedded in one of the molds 3, and the second magnet 19 is fixedly embedded in the other mold 3. The first magnet 18 and the second magnet 19 attract and cooperate with each other. The fixed component can be set to two groups, which can be adjusted according to specific usage conditions.

[0049] Specifically, after the two molds 3 move toward each other and come close to each other, under the attraction of the first magnet 18 and the second magnet 19, the two molds 3 form a whole, and the two arc grooves 34 are connected and matched; at the same time, the insert 17 is inserted into the inside of the socket 16, and the two inner cavities 12 are connected.

[0050] In order to control the movement of the slider 6, an L-shaped frame 10 is fixedly connected to the outer wall of the mold 3, a first electric push rod 11 is fixedly connected to the L-shaped frame 10, a vertical plate 9 is fixedly connected to the telescopic end of the first electric push rod 11, a round rod 8 is fixedly connected to the slider 6, and one end of the round rod 8 away from the slider 6 is fixedly connected to the corresponding vertical plate 9.

[0051] A wind power component is provided on one of the square plates 2, and the wind power component includes a processing box 13, a pump body 14, a first air pipe 15 and a telescopic tube 26. The processing box 13 is fixedly connected to the square plate 2, and a filtering device and a condensing device are provided inside the processing box 13. The filtering device includes a filter screen and other structures, which can filter dust; the condensing device includes a condensing plate and other structures, which can condense water vapor. The filtering device and the condensing device are both existing common technologies and are not described in detail here. One end of the first air pipe 15 is connected to the corresponding inner cavity 12, and the other end of the first air pipe 15 is connected to the processing box 13. The first air pipe 15 is a soft material and does not affect the rotation of the mold 3 and other structures. The pump body 14 is fixedly connected to the top of the processing box 13, the air inlet end of the pump body 14 is connected to the processing box 13, and the telescopic tube 26 is connected to the air outlet end of the pump body 14.

[0052] After heating for a certain period of time, the telescopic end of the first electric push rod 11 is controlled to be retracted, and the slider 6 is driven to move in the direction away from the insulator blank inside the through groove 5 through the vertical plate 9 and the round rod 8, so that there is a certain suction space between the slider 6 and the insulator blank; and the slider 6 is staggered with the air hole 7, and the inner cavity 12 can be connected with the through groove 5 through the air hole 7. The pump body 14 is started, and the pump body 14 sucks the water vapor in the suction space through the first air pipe 15, the inner cavity 12, and the air hole 7 to improve the efficiency of heating and forming.

[0053] The gas is condensed and dried inside the processing box 13 and discharged to the outside through the telescopic tube 26 to prevent water vapor from affecting the processing environment.

[0054] By setting up structures such as electric heating wires, air holes 7, sliders 6, etc., the insulating component blank can be effectively heated to remove excess moisture in the insulating component blank, thereby increasing the hardness of the insulating component blank to reduce the problem of collapse and deformation of the insulating component blank. At the same time, water vapor can be sucked out to improve the efficiency of heating and molding.

[0055] The operator can rotate the mold 3 to change the position of the suction space, expand the water vapor suction range, and further improve the efficiency of heating and forming; rotating the mold 3 can effectively avoid the insulating blank from sticking to the mold 3. At this time, the lifting plate 33 and the support box 20 limit the insulating blank.

[0056] After heating and forming, the telescopic end of the first electric push rod 11 is controlled to extend, so that the slider 6 is reset and fits on the outer wall of the insulator blank; then the motor 30 is controlled to reverse, and the threaded rod 29 is driven to rotate by the motor 30, and the threaded rod 29 drives the two molds 3 to move back to each other through the slide plate 28 and the square plate 2, and the two molds 3 are separated; in this process, the telescopic end of the first electric push rod 11 is controlled to continue to extend, and the formed insulator blank is pushed to automatically disengage through the slider 6, which is convenient for the subsequent removal of the insulation blank; at the same time, the telescopic end of the second electric push rod 32 is controlled to be recovered, and the lifting plate 33 is driven to move upward. Since the contact area of ​​the slider 6 is large, damage to the insulator can be avoided.

[0057] Considering that dust and the like are easily accumulated inside the mold 3, in order to clean the dust and avoid affecting the quality of the insulator, a second air pipe 25 is connected to the side of the support box 20, and the second air pipe 25 cooperates with the telescopic tube 26. The threaded barrel 21 is equipped with a cleaning assembly, which includes a vertical pipe 23 and a blow pipe 24. The blow pipe 24 is arranged in multiple numbers. The vertical pipe 23 is threadedly matched with the threaded barrel 21. The blow pipe 24 is connected to the side of the vertical pipe 23, and the multiple blow pipes 24 are evenly distributed.

[0058] Specifically, when it is necessary to clean the dust inside the mold 3, remove the cap 22 and dock the cleaning assembly with the threaded cylinder 21; start the motor 30, the motor 30 drives the threaded rod 29 to rotate, and the threaded rod 29 drives the two molds 3 to move toward each other and close together through the slide plate 28 and the square plate 2, and at the same time, the lifting plate 33 is pushed downward by the second electric push rod 32, and the lifting plate 33, the support box 20 and the two molds 3 cooperate to form a cleaning space; then dock the telescopic tube 26 with the second air pipe 25.

[0059] The telescopic end of the first electric push rod 11 is controlled to be retracted, and the slider 6 is staggered from the air hole 7 . At this time, the inner cavity 12 can be communicated with the through groove 5 through the air hole 7 .

[0060] The pump body 14 is started, and the pump body 14 delivers gas to the inside of the tray 20 through the telescopic tube 26 and the second air pipe 25, and blows gas to the inner wall of the mold 3 through the vertical pipe 23 and the blowpipe 24 to blow away the dust on the inner wall of the mold 3. At the same time, the operator can rotate the mold 3 to change the position where the gas acts, and complete the cleaning of the two molds 3. In addition, since the lifting plate 33, the tray 20 and the two molds 3 cooperate to form a cleaning space, the cleaning efficiency can be improved. At the same time, the pump body 14 sucks the blown dust through the first air pipe 15, the inner cavity 12, and the air hole 7. A single pump body 14 blows away and sucks at the same time, reducing energy consumption, and the dust is filtered inside the processing box 13.
