[0002] Glass insulator is a device made of glass used to support and insulate conductors. It is one of the key components of high-voltage transmission lines. Its performance directly affects the safe operation of the entire transmission line. The production of glass insulators generally involves pouring molten glass into the corresponding female mold, and then pressing and molding the male mold.

[0026] 2. Driven by the hydraulic column, when demoulding is required, the hydraulic column pushes the movable block up. The movable block cooperates with the strip-shaped limiting hole on the inner side of the through groove through the limiting block to ensure its precise positioning during the rising and falling process. Since the movable block contacts the bottom of the mold cavity, the formed glass insulator can be smoothly ejected to achieve automatic demoulding. This process does not require additional power equipment, reduces manufacturing costs, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] Reference Figure 1-8A glass insulator lower mold with a self-cooling structure and a method of using the same include a cooling chamber 1, which is the main cooling component of the entire lower mold. The cooling chamber 1 is used to circulate the internal coolant to reduce the overall temperature of the lower mold, thereby providing a good cooling environment for the glass insulator. The left and right ends of the cooling chamber 1 are respectively provided with an inlet pipe 101 and an outlet pipe 102 for circulating the coolant. The coolant circulates in the cooling chamber 1, thereby effectively reducing the temperature of the surrounding environment. The corresponding sides of the inlet pipe 101 and the outlet pipe 102 are connected with an elastic tube 8. A lock buckle 10 is provided on the outer wall of the elastic tube 8. When the external thread 701 and the internal thread 202 are installed in coordination, the elastic tube 8 is butted against the butt pipe 9 and is fixedly connected by the lock buckle 10. The cooling chamber 1 is provided with a plurality of locking buckles 10, and the outer wall of the elastic tube 8 is provided with a plurality of locking buckles 10. The outer wall of the elastic tube 8 ... A mounting groove 103 is provided at the bottom of the inner cavity of the cooling chamber 1, and a water reservoir 7 is fixedly installed on the mounting groove 103. An internal thread 202 is provided on the inner side of the disc carrier 2, and an external thread 701 is provided on the upper outer part of both ends of the water reservoir 7, and a docking pipe 9 is provided about the lower part of the external thread 701. In actual use, the water reservoir 7 is first installed on the disc carrier 2 through the cooperation of the external thread 701 and the internal thread 202, and then the bottom of the water reservoir 7 is installed on the mounting groove 103, and then the elastic tube 8 is docked with the docking pipe 9 and fixed by the lock 10. After the cooling system is turned on, the cooling water enters the water reservoir 7 through the water inlet end pipe 101 to cool the glass insulator, and the cooled water is discharged from the water outlet end pipe 102 through the elastic tube 8 and the docking pipe 9 on the other side to realize the circulation of the coolant.

[0038] A disc carrier 2 is arranged on the top of the cooling chamber 1, and an annular groove 201 is opened on the disc carrier 2. The circular lower template 3 is installed correspondingly on the annular groove 201 of the disc carrier 2. The annular groove 201 is an annular installation groove designed on the disc carrier 2, which provides a stable and accurate rotation track for the rotating shaft 501. The inner wall of the annular groove 201 is smooth to ensure that the rotating shaft 501 can rotate smoothly inside it. The annular groove 201 also ensures the accuracy and stability of the lower template during the rotation process. The installation cylinder 4 is correspondingly arranged on both sides of the bottom of the disc carrier 2. The bottom of the installation cylinder 4 is fixedly connected with a side column 6, and a cross base 23 is arranged at the bottom of the support column 5 and the side column 6;

[0039] The bottom of the cooling chamber 1 is fixedly connected with a supporting column 5, and a rotating shaft 501 is provided inside the supporting column 5, and the rotating shaft 501 passes through the cooling chamber 1 to the bottom of the circular lower template 3, and the top of the rotating shaft 501 is fixedly connected to the connecting bearing 302. A sealing ring 502 is provided on the through hole between the rotating shaft 501 and the water reservoir 7 to ensure the sealing of the coolant. The rotation of the rotating shaft 501 can drive the circular lower template 3 to rotate, so as to realize cooling and demolding at different positions.

[0040] Among them, a mounting hole 301 is opened at the center of the top surface of the circular lower template 3, and a connecting bearing 302 is arranged on the mounting hole 301. Four mold cavities 303 are evenly installed on the top surface of the circular lower template 3. The disc carrier 2 is about the vertical surface of the mounting cylinder 4, and a ring plate 11 is arranged at the bottom of the mold cavity 303. A plurality of cold air holes 12 are vertically arranged inside the ring plate 11. A through groove 14 is opened in the center of the bottom surface of the mold cavity 303, and a movable block 13 is installed on the through groove 14. The movable block 13 moves up and down under the drive of the hydraulic column 18 to realize the automatic demoulding function, and a strip-shaped limiting hole 15 is opened on the inner side of the through groove 14. The movable block 13 is arranged corresponding to the ring plate 11, and a limiting block 16 is arranged on the bottom outer wall of the movable block 13. The through groove 14, The strip limiting hole 15 and the limiting block 16 jointly ensure the stable movement and precise positioning of the movable block 13. During implementation, the movable block 13 cooperates with the strip limiting hole 15 through the limiting block 16 at the bottom to ensure stability during the rising and falling process. Specifically, through the drive of the hydraulic column 18, when demoulding is required, the hydraulic column 18 pushes the movable block 13 to rise, and the movable block 13 cooperates with the strip limiting hole 15 on the inner side of the through groove 14 through the limiting block 16 to ensure its precise positioning during the rising and falling process. Since the movable block 13 contacts the bottom of the mold cavity 303, the molded glass insulator can be smoothly ejected to achieve automatic demoulding. This process does not require additional power equipment, reduces manufacturing costs, and improves production efficiency.

[0041] The mounting tube 4 extends to the inner cavity of the disc carrier 2 and is provided with a cooling chamber 2 17. The top plate of the cooling chamber 2 17 is provided with a cooling hole 1701 corresponding to the cooling air through hole 12 to ensure that the cooling air can smoothly and evenly enter the bottom of the mold cavity 303. The bottom of the movable block 13 penetrates into the inner cavity of the cooling chamber 2 17. A hydraulic column 18 is installed inside the cooling chamber 2 17 and below the movable block 13. A mounting frame 19 is provided at the bottom of the hydraulic column 18, and a cooling fan 20 is fixedly installed on the inner frame of the mounting frame 19. The cooling fan 20 serves as a cooling air source to provide the required cooling air for the cooling chamber 2 17. By adjusting the speed and power of the cooling fan 20, the flow rate and temperature of the cold air can be controlled, so as to achieve different cooling requirements for the glass insulator. The bottom of the cooling fan 20 is connected with a connecting rod 21, and the bottom of the connecting rod 21 is fixedly provided with a loading and unloading plate 22. Specifically, when the cooling fan 20 is started, the cold air evenly enters the bottom of the mold cavity 303 through the cold delivery hole 1701, so as to achieve effective cooling of the glass insulator. Specifically, by setting a cooling chamber 1, the coolant circulates in the cooling chamber 1, effectively reducing the ambient temperature around the mold cavity 303, and preliminarily cooling the lower mold. Then, the circular lower mold plate 3 is driven to rotate forty-five degrees by the rotating shaft 501. The preliminarily cooled lower mold is located above the cooling chamber 2 17 at this time. The cold air through hole 12 is used to directly send the cold air into the bottom of the mold cavity 303, so as to perform secondary cooling on the mold, which is beneficial to the efficient molding and discharging of the glass insulator, improves the cooling efficiency, and effectively avoids product defects caused by excessive temperature. The hydraulic column 18 and the cooling fan 20 are both existing mature technologies and will not be described in detail here.

[0043] S1: Install the water reservoir 7 through its external thread 701 and the internal thread 202 of the disc carrier 2, and fix the butt pipe 9 and the elastic pipe 8 through the lock buckle 10 to ensure that the coolant enters the water reservoir 7 smoothly, and then install the cooling chamber 1;

[0044] S2: Install the circular lower template 3 onto the rotating shaft 501 through the connecting bearing 302 at the bottom thereof to ensure a stable installation;

[0045] S3: Ensure that the installation cylinder 4 matches the bottom two sides of the disc carrier 2. A cooling chamber 2 17 is provided in the inner cavity of the disc carrier 2 where the installation cylinder 4 extends. At this time, the cooling chamber 2 17 needs to be docked with the cooling fan 20, and the hydraulic column 18 is docked above the cooling fan 20.

[0046] S4: Inject the required materials into the mold cavity 303 of the circular lower mold plate 3 to start working, and at the same time introduce the coolant into the cooling chamber 1 through the water inlet end pipe 101, and circulate through the water outlet end pipe 102 to ensure that the coolant continues to circulate in the cooling chamber 1. After the lower mold is cooled by water in the water reservoir 7, the rotating shaft 501 drives the circular lower mold plate 3 to rotate forty-five degrees, and then start the cold air fan 20 to allow the cold air to enter the bottom of the mold cavity 303 through the cold air through hole 12, so as to achieve secondary uniform cooling of the mold cavity 303, and finally push the movable block 13 through the hydraulic column 18, which is conducive to the demolding of the glass insulator.
