[0015] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0016] See also Figure 1 , Figure 2 as well as Figure 3 The present embodiment provides a molding die for processing a resin insulator, comprising a bottom box 10, a first driving assembly 20, a supporting assembly 30, a square block 40, a cleaning assembly 50, a water changing assembly 60 and a second driving assembly 70. The supporting assembly 30 is provided with two groups, and the two groups of the supporting assembly 30 are movably arranged on the upper part of the bottom box 10 and are relatively distributed. The square block 40 is provided with two groups, and the two groups of the square blocks 40 are respectively rotatably arranged on the upper part of the two groups of the supporting assembly 30. The four side walls of the two groups of the square blocks 40 are provided with half mold cavities 402, and the insides of the two groups of the square blocks 40 are provided with water storage chambers 403. The first driving assembly 20 is installed on the upper part of the bottom box 10, and is used to drive the two groups of the supporting assembly 30 to move back and forth, so as to achieve contact between the two groups of the square blocks 40. And separation, the cleaning component 50 is provided with two groups, the two groups of the cleaning components 50 are respectively arranged on the sides of the two groups of the square blocks 40, the second driving component 70 is arranged at the bottom of the square block 40, when the two groups of the square blocks 40 are separated, the second driving component 70 is used to drive the square block 40 to rotate 90°, so that the two half-mold cavities 402 previously involved in the molding are respectively opposite to the two groups of the cleaning components 50, one end of the water changing component 60 extends to the top of the square block 40, and the other end extends to the inside of the water storage chamber 403. When the two groups of the square blocks 40 are separated, the water changing component 60 is used to replace the cooling water in the water storage chamber 403 and drive the replaced cooling water into the inside of the cleaning component 50 to serve as a cleaning water source for the two half-mold cavities 402.

[0017] When performing injection molding of the resin insulator, the first driving component 20 can be used to drive the two groups of support components 30 to move toward each other, and the two groups of support components 30 drive the two groups of square blocks 40 to move toward each other until the two groups of square blocks 40 contact each other, and the half mold cavities 402 on the contact surfaces of the two groups of square blocks 40 are closed into a complete mold cavity, and then an external injection molding machine (not shown in the figure) injects the molten resin raw material into the mold cavity, and at the same time, the cooling water in the water storage chamber 403 in the two groups of square blocks 40 is used to cool the molten resin raw material in the mold cavity, thereby realizing the rapid molding of the resin insulator. After the molding of the resin insulator is completed, the first driving component 20 drives the two groups of The supporting components 30 move away from each other, thereby separating the two groups of square blocks 40, and the resin insulator formed in the mold cavity falls out by itself, realizing automatic demolding of the resin insulator. After the demolding of the resin insulator is completed, the second driving component 70 drives the two groups of square blocks 40 to rotate 90°, so that the two half mold cavities 402 originally involved in the molding rotate to one side of the two groups of cleaning components 50 and face the two groups of cleaning components 50. Then, the water changing component 60 replaces the cooling water in the water storage chamber 403 in the two groups of square blocks 40, and the replaced cooling water enters the interior of the cleaning component 50, and is then transported by the cleaning component 50 to the interior of the half mold cavity 402 facing it, thereby realizing the half mold. The inner wall of the cavity 402 is cleaned to prevent the resin raw material from remaining on the inner wall of the half-mold cavity 402, thereby improving the subsequent molding effect of the resin insulator; when the inner wall of the half-mold cavity 402 is cleaned, the first driving component 20 drives the two groups of support components 30 to move toward each other again, so that the two groups of square blocks 40 are in contact again. When the two groups of square blocks 40 are in contact again, the half-mold cavity 402 on one side wall is closed again to form a complete mold cavity, and the external injection molding machine injects the molten resin raw material into the mold cavity again to realize the molding of the resin insulator again, and then the first driving component 20 drives the two groups of support components 30 away again, so that the two groups of square blocks 40 are separated again. To realize the demolding of the resin insulator again, the second driving component 70 drives the two groups of square blocks 40 to rotate 90° again, and then rotates the semi-mold cavity 402 that will participate in the subsequent molding to the side of the cleaning component 50 again, and the water changing component 60 replaces the cooling water in the water storage chamber 403 again, and the replaced cooling water is transported to the interior of the semi-mold cavity 402 through the cleaning component 50 again, so as to realize the reciprocating cycle, which can realize the continuous automatic molding of the resin insulator. At the same time, the semi-mold cavity 402 that participates in the molding can be cleaned in time to avoid the resin raw material from remaining on the inner wall of the semi-mold cavity 402, thereby improving the molding quality of the resin insulator.

[0018] See also Figure 1In one embodiment, the two groups of support assemblies 30 have the same structure, both including a support rod 301 and a support seat 302 fixedly arranged on one side of the support rod 301, and the two groups of square blocks 40 are rotatably arranged on the upper part of the two groups of support seats 302 respectively. The first driving assembly 20 includes a motor 201 and a rotating shaft 203. The motor 201 is fixedly installed on the upper part of the bottom box 10, and the rotating shaft 203 is installed at the output end of the motor 201. Two groups of threaded segments 202 with opposite rotation directions are arranged on the outside of the rotating shaft 203. The rotating shaft 203 passes through the two groups of support rods 301 and is threadedly matched with the two groups of support rods 301 through the two groups of threaded segments 202.

[0019] The motor 201 drives the rotating shaft 203 to rotate alternately forward and reverse. When the rotating shaft 203 rotates forward, the two sets of threaded segments 202 and the threads of the two sets of support rods 301 cooperate to drive the two sets of support rods 301 to move toward each other, and then the two sets of support seats 302 drive the two sets of square blocks 40 to approach each other and contact each other, so that the two half mold cavities 402 on the contact surfaces of the two sets of square blocks 40 are closed to form a complete mold cavity; when the rotating shaft 203 rotates reversely, the two sets of threaded segments 202 and the reverse threads of the two sets of support rods 301 cooperate to drive the two sets of support rods 301 to move away from each other, and then the two sets of support seats 302 drive the two sets of square blocks 40 to separate, so that the resin insulator formed in the mold cavity falls out by itself.

[0020] See also Figure 1 In one embodiment, a guide rod 101 is fixedly provided on the upper part of the bottom box 10, and the guide rod 101 passes through the two groups of support rods 301 and slidably cooperates with the two groups of support rods 301, and the guide rod 101 and the rotating shaft 203 are parallel to each other.

[0021] Through the active cooperation between the guide rod 101 and the two groups of support rods 301, a guiding effect can be provided for the movement of the two groups of support rods 301, so that the two groups of support rods 301 can be driven to move smoothly when the rotating shaft 203 rotates.

[0022] Please refer to the figure Figure 1 , Figure 2 as well as Figure 4In one embodiment, a support column 303 is fixedly provided on the upper part of the support seat 302, a pipe 401 communicating with the water storage chamber 403 is provided at the bottom of the square block 40, and the lower end of the pipe 401 is rotatably connected to the support column 303 through a rotating joint, and the second driving assembly 70 includes a gear 701, a support plate 702, a beveled tooth piece 703 and a second elastic member 704, the gear 701 is fixedly provided on the outside of the pipe 401, the support plate 702 is provided on one side of the gear 701 and is fixedly connected to the upper part of the bottom box 10, and the beveled tooth piece 703 is provided with a plurality of groups, and a plurality of the beveled tooth pieces 703 are hingedly provided on one side of the support plate 702 and are spaced apart along the length direction of the support plate 702, and one side of each group of the beveled tooth pieces 703 is connected to the support plate 702 through a group of the second elastic member 704, and a plurality of the beveled tooth pieces 703 can be unidirectionally meshed with the gear 701.

[0023] When the motor 201 drives the rotating shaft 203 to rotate forward and drives the two groups of square blocks 40 to approach each other, the pipe 401 at the bottom of the square block 40 drives the gear 701 to move along one side of the support plate 702. At this time, the gear 701 pushes the plurality of beveled teeth 703 in turn, so that the plurality of beveled teeth 703 are deflected in turn compared with the support plate 702. The gear 701 cannot mesh with the plurality of beveled teeth 703. The two groups of square blocks 40 keep moving smoothly and contact accurately, so that the two half-cavities 402 on the contact surfaces of the two groups of square blocks 40 are accurately closed. When the motor 201 drives the rotating shaft 203 to rotate in the opposite direction and then drives the two groups of square blocks 40 to separate, the gear 701 outside the pipe 401 at the bottom of the square block 40 moves in the opposite direction along one side of the support plate 702. At this time, the gear 701 and the plurality of beveled teeth 703 enter into a meshing state. The plurality of beveled teeth 703 push the gear 701 and then drive the pipe 401 to rotate 90° compared to the support column 303, thereby driving the square block 40 to rotate 90°, so that the half-mold cavity 402 originally involved in the molding rotates to face the cleaning component 50.

[0024] See also Figure 1 , Figure 2 as well as Figure 3In one embodiment, a water inlet pipe 304 is fixedly provided on the side wall of the support column 303, and one end of the water inlet pipe 304 away from the support column 303 is connected to an external water tank (not shown in the figure) through a hose (not shown in the figure). The cleaning component 50 includes a cleaning pipe 501, one end of which is connected to the support column 303, and the other end extends to the side of the square block 40. The cleaning pipe 501 is provided with a plurality of spray holes 502 on the side facing the square block 40. A one-way valve (not shown in the figure) is provided in the water inlet pipe 304 and the cleaning pipe 501. A bracket plate 102 is fixedly provided on the upper part of the bottom box 10. A wedge-shaped plate 103 is fixedly arranged at the bottom of the plate 102, and the water changing assembly 60 includes a first elastic member 601, a pressure rod 603 and a piston plate 604, and the piston plate 604 is movably arranged inside the water storage chamber 403. The lower end of the pressure rod 603 is connected to the piston plate 604, and the upper end passes through the top wall of the square block 40 and extends to the top of the square block 40. An annular stopper 602 is fixedly arranged on the side wall of the pressure rod 603, and one end of the first elastic member 601 is connected to the annular stopper 602, and the other end is connected to the square block 40, which is used to provide elastic support for the pressure rod 603, so that the upper end of the pressure rod 603 is against the wedge plate 103.

[0025] When the two groups of square blocks 40 are separated and the half mold cavity 402 previously involved in the forming rotates to face the cleaning pipe 501, the upper end of the pressure rod 603 slides down along the inclined surface of the wedge plate 103, and the wedge plate 103 pushes the pressure rod 603 so that the pressure rod 603 moves downward compared to the square block 40, thereby driving the piston plate 604 to move downward along the inside of the water storage chamber 403. At this time, the one-way valve inside the water inlet pipe 304 is closed, and the one-way valve inside the cleaning pipe 501 is opened. The first elastic member 601 is compressed, and the piston plate 604 presses the cooling water inside the water storage chamber 403 through the pipeline 401 and the support column 303 to The inside of the cleaning pipe 501 is then sprayed out from a plurality of spray holes 502 on the side wall of the cleaning pipe 501, thereby acting on the inner wall of the half-mold cavity 402 to clean the residual resin raw material on the inner wall of the half-mold cavity 402. After the inner wall of the half-mold cavity 402 is cleaned, as the motor 201 drives the rotating shaft 203 to rotate forward, the two groups of square blocks 40 approach each other, and the corresponding pressure rod 603 slides along the inclined surface of the wedge plate 103 under the support of the first elastic member 601, thereby driving the piston plate 604 to move upward along the inside of the water storage chamber 403. At this time, the one-way valve inside the water inlet pipe 304 is opened, and the cleaning pipe 50 1 The internal one-way valve is closed, and the piston plate 604 draws the cooling water in the external water tank into the water storage chamber 403 through the hose, the water inlet pipe 304, the support column 303 and the pipeline 401 to achieve the replacement of the cooling water, so as to better cool the resin insulator to be subsequently formed; the cooling water that is pressed into the cleaning pipe 501 through the water storage chamber 403 participates in the cooling heat exchange of the resin insulator, so the cooling water entering the cleaning pipe 501 has a certain amount of heat, and when the cooling water with a certain amount of heat is sprayed to the inner wall of the semi-mold cavity 402 through the spray hole 502, The temperature difference between the cooling water and the half-mold cavity 402 can be reduced, thereby avoiding the shrinkage and deformation of the half-mold cavity 402 due to the excessively low temperature of the cooling water during the cleaning process of the half-mold cavity 402, thereby ensuring the molding quality of the resin insulator. After the half-mold cavity 402 is cleaned, a small amount of water stains will remain inside the half-mold cavity 402. These residual water stains will accompany the subsequent molding of the resin insulator. The heat of the resin insulator can heat the square block 40. The square block 40 is heated and then evaporates the residual water stains in the half-mold cavity 402, thereby further ensuring the molding quality of the resin insulator.

[0026] See also Figure 3 In one embodiment, a collecting port 104 is opened on the upper portion of the bottom box 10. After the cooling water acts on the inner wall of the half-mold cavity 402 to clean the half-mold cavity 402, the cooling water flows to the upper portion of the bottom box 10, and then flows into the interior of the bottom box 10 through the collecting port 104, thereby collecting and storing the cooling water.

[0027] In one embodiment, the first elastic member 601 and the second elastic member 704 may be springs or metal springs, which are not limited herein.

[0028] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
