Description

Technical Field

[0001] This invention relates to the field of insulator production equipment technology, specifically to a multi-umbrella glass insulator production mold and its manufacturing process. Background Technology

[0002] Multi-umbrella glass insulator production molds provide a stable and precise molding environment for glass insulator production. The design and structure of the casting mold directly affect the quality, performance, and production efficiency of the insulator. Generally, this type of mold consists of several parts, including the mold body, gate, venting holes, and cooling system. The mold body is usually made of high-temperature and corrosion-resistant materials to ensure that it does not deform or break during the pouring of molten glass at high temperatures. The shape and dimensions inside the mold must match the requirements of the final product to ensure that the insulator maintains the required shape and size after cooling. In addition, the design of the mold's venting holes is also very important. It can effectively expel the gas generated during the pouring process, prevent the formation of bubbles, and thus improve the mechanical strength and electrical performance of the insulator. For example, the high-voltage insulator production molding die disclosed in authorization announcement number CN219727007U includes a lower die and an upper die above the lower die. An injection pipe is connected to the upper surface of the upper die. Both the lower and upper dies have insulator skirt cavities on their adjacent sides. One of the insulator skirt cavities has an exhaust port on its inner bottom wall. This is achieved by creating a semi-circular groove in the insulator skirt cavity and placing a semi-circular elastic pad on the inner wall of the groove. When the upper and lower dies are engaged, the semi-circular elastic pad can limit the mandrel's movement, effectively preventing it from sliding. A first heat dissipation vent and a second heat dissipation vent are respectively created on the surfaces of the lower and upper dies to facilitate heat dissipation from the insulator skirt cavity. The existing multi-umbrella glass insulator production mold structure and operation method are basically the same. The process involves closing the upper and lower molds containing the grooves for multi-umbrella glass insulators, allowing molten glass to flow smoothly into the molds and undergo forming and cooling. However, after the multi-umbrella glass insulators are formed, they remain in the lower mold. After the upper and lower casting molds are separated, workers need to reach between them to remove the multi-umbrella glass insulators from the lower mold one by one. In the existing mold structure for producing multi-umbrella glass insulators, the lower mold is in a horizontal position. For larger or heavier multi-umbrella insulators, this horizontal position puts workers in an unnatural posture for handling the material, making the application of force difficult and inconvenient. Furthermore, the limited operating space between the upper and lower molds means that each glass insulator must be removed carefully, further reducing the material handling speed. Summary of the Invention

[0003] The purpose of this invention is to provide a production mold and process method for multi-umbrella glass insulators. A main hydraulic cylinder on the mold frame drives the inverted U-shaped hanger, tilting support structure, and lower casting mold to rise and fall, while a secondary hydraulic cylinder drives the upper template and upper casting mold to rise and fall, allowing the lower and upper casting molds to close or open. After the mold completes the injection, casting, and cooling processes, the main hydraulic cylinder drives the lower casting mold to move downwards. During this downward movement, a gear self-locking transmission assembly and tilting support structure cause the lower casting mold to rotate along its A-axis, causing the multi-umbrella glass insulator components remaining on the lower casting mold to face the worker, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a multi-umbrella type glass insulator production mold, comprising: The mold frame has two double-column slides that can slide along the Z-axis installed on its left and right inner walls. A tilting support structure is installed at the top of each of the two double-column slides, and a lower casting mold is installed at the top of the tilting support structure. An upwardly extending inverted U-shaped hanger is installed on the outer wall of the two double-column slides on their opposite sides. A main hydraulic cylinder that drives the inverted U-shaped hanger to lift and lower along the Z-axis is installed at the top of the mold frame. A secondary hydraulic cylinder is installed at the top of the mold frame on one side of the main hydraulic cylinder. An upper template is installed at the bottom of the piston rod of the secondary hydraulic cylinder, and an upper casting mold is installed on the lower surface of the upper template. A feeding casting head is installed on one side of the back of the upper casting mold. A dual-zone water cooler is installed at the bottom of the lower casting mold and the top of the upper casting mold. A gear self-locking transmission assembly is installed at the top of one of the double-column slides. The gear self-locking transmission assembly is used to convert the Z-axis lifting motion of the double-column slide into the A-axis rotational motion of the tilting support structure and the lower casting mold. A telescopic support module is provided on the back of the mold frame. The telescopic support module is used to support the lower surface of the tilting support structure after the lower casting mold and the upper casting mold are closed. A PLC control panel is installed on one side of the mold frame surface. The output terminal of the PLC control panel is electrically connected to the input terminal of the main hydraulic cylinder, the auxiliary hydraulic cylinder, and the telescopic support module, respectively.

[0005] Preferably, two symmetrical guide rods are installed on the left and right inner walls of the mold frame, and the double-column slide table slides in cooperation with the two guide rods.

[0006] Preferably, connecting columns are installed on both sides of the top of the inverted U-shaped hanger. The connecting columns are located between the two guide rods, and the bottom end of the connecting column is fixedly connected to the top end of the double-column slide.

[0007] Preferably, the tilting support structure includes a bearing seat fixed to the top of the two double-column slides, a rotating shaft rotatably mounted inside the bearing seat, and a support frame installed between the opposite ends of the two rotating shafts. The dual-zone water cooler and the lower casting mold are sequentially installed on the top of the support frame.

[0008] Preferably, a horizontal sensor for detecting the tilt angle of the support frame and the lower casting mold is installed on one side of the bottom end of the support frame, and the output end of the horizontal sensor is electrically connected to the input end of the PLC control panel.

[0009] Preferably, the gear self-locking transmission assembly includes a bearing housing two fixed on one outer wall of one of the double-column slides, a main shaft rotatably mounted inside the bearing housing two, and a rack mounted on one inner wall of the mold frame. One end of the main shaft surface is equipped with a driven gear that meshes with the rack. The extended line of the central axis of the main shaft is perpendicular to the extended line of the central axis of the rotary shaft. The end of the main shaft near the rotary shaft is equipped with a worm gear transmission structure for driving the rotary shaft, support frame, and lower casting mold to rotate.

[0010] Preferably, the worm gear transmission structure includes a worm fixed to the other end of the main shaft and a worm wheel fixed to one end of the surface of the rotating shaft, and the worm wheel and the worm mesh with each other.

[0011] Preferably, the dual-zone water cooler includes a hollow sheet metal frame fixed to the top of the support frame, S-shaped water cooling pipes on both sides inside the hollow sheet metal frame, and a number of heat dissipation fins evenly spaced on the outer circumference of the S-shaped water cooling pipes, and the lower casting mold is fixed to the top of the hollow sheet metal frame.

[0012] Preferably, the telescopic support module includes two columns fixed to the back of the mold frame, a right-angle cylinder seat fixed close to the outer wall of the two columns, and a support platform slidably installed at the bottom of the right-angle cylinder seat. One of the right-angle cylinder seats is equipped with a Y-axis hydraulic cylinder for driving the support platform to move along the Y-axis. After the Y-axis hydraulic cylinder pushes the support platform to move along the Y-axis, the upper surface of the support platform comes into contact with the lower surface of the support frame.

[0013] This invention also provides a manufacturing process for multi-umbrella glass insulators, including the multi-umbrella glass insulator manufacturing mold described above, comprising the following steps: S101: Check the working status of the mold frame, PLC control panel, main hydraulic cylinder and auxiliary hydraulic cylinder to ensure that all equipment is operating normally. Install the lower casting mold onto the two double column slides and ensure that the lower casting mold is well connected to the double column slides. The upper template and upper casting mold also need to be installed in place to ensure that they can be smoothly closed with the lower casting mold. S102: The auxiliary hydraulic cylinder controls the Z-axis position of components such as the inverted U-shaped hanger, double-column slide, lower casting mold, and tilting support structure. The auxiliary hydraulic cylinder controls the Z-axis position of the upper template and upper casting mold until the lower casting mold and upper casting mold are moved to the mold closing position. After the lower casting mold and upper casting mold are closed, the operator connects the feeding casting head to the casting system, and the molten glass material produced by the melting furnace is injected into the mold until the molten glass material evenly fills every corner of the mold. S103: After the casting material is fed, the staff starts the dual-zone water cooler on the lower casting mold and the upper casting mold. The dual-zone water cooler begins to cool the mold. S104: After cooling is complete, the main hydraulic cylinder begins to drive the inverted U-shaped hanger, double column slide, and lower casting mold to move downward. During the downward movement, the gear self-locking transmission assembly and tilting support structure are used to make the lower casting mold rotate on the A-axis. The downward movement of the double column slide and the lower casting mold on the Z-axis is converted into the positive rotation movement of the tilting support structure and the lower casting mold on the A-axis through the gear self-locking transmission assembly, thereby gradually moving the multi-umbrella glass insulators stuck in the lower casting mold toward the workers. S105: After the lower casting mold completes the A-axis rotation, the workers can remove the insulator parts formed on the lower casting mold, and clean the upper and lower molds to remove residual materials and impurities, in preparation for the next processing operation.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This multi-umbrella glass insulator production mold and its process method utilize a structure comprising a tilting support structure, a double-column slide, and a gear self-locking transmission assembly, among other mutually cooperating components. The main hydraulic cylinder on the mold frame drives the inverted U-shaped hanger, the tilting support structure, and the lower casting mold to rise and fall, while the auxiliary hydraulic cylinder drives the upper template and the upper casting mold to rise and fall, allowing the lower and upper casting molds to close or open. The main hydraulic cylinder drives the lower casting mold to move downwards. During this downward movement, the gear self-locking transmission assembly and the tilting support structure cause the lower casting mold to rotate along its A-axis, causing the multi-umbrella glass insulator components remaining on the lower casting mold to face the operator. The rotated mold allows the product removal position to be directly adjusted to the most suitable direction, requiring only simple removal by the operator. The material handling mechanism allows for quick and easy operation, significantly reducing material handling time. For complex and heavy castings like multi-umbrella glass insulators, the A-axis rotation of the lower casting mold allows workers to operate from a more natural and comfortable angle, enabling them to complete material handling in a fixed and stable posture, thus greatly reducing labor intensity. Furthermore, with traditional horizontal molds, workers' hands and bodies may come into contact with the mold edges or other potentially dangerous parts during material handling, increasing the risk of injury. However, the rotation of the gear self-locking transmission assembly and tilting support structure keeps the lower casting mold and the formed insulator in an inclined state, increasing the space available to workers on the lower casting mold. Workers can handle materials from a safe distance, reducing the possibility of accidental injury. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] Example 1, by Figures 1 to 4 The present invention includes a mold frame 1, on the left and right inner walls of the mold frame 1, there are double column slides 4 that can slide along the Z-axis, the top of the two double column slides 4 are equipped with tilting support structures 5, and the top of the tilting support structures 5 are equipped with a lower casting mold 6. The outer wall of the two double column slides 4 that are far apart is equipped with an upwardly extending inverted U-shaped hanger 3. The top of the mold frame 1 is equipped with a main hydraulic cylinder 2 that drives the inverted U-shaped hanger 3 to lift and lower along the Z-axis. The top of the mold frame 1 on one side of the main hydraulic cylinder 2 is equipped with a secondary hydraulic cylinder 8. The bottom of the piston rod of the secondary hydraulic cylinder 8 is equipped with an upper template 9, and the lower surface of the upper template 9 is equipped with an upper casting mold 10. The back side of the upper casting mold 10 is equipped with a feeding casting head 13. The bottom of the lower casting mold 6 and the top of the upper casting mold 10 are both provided with dual-zone water coolers 14. A gear self-locking transmission assembly 7 is installed at the top of one of the double-column slides 4. The gear self-locking transmission assembly 7 is used to convert the Z-axis lifting motion of the double-column slide 4 into the A-axis rotation motion of the tilting support structure 5 and the lower casting mold 6. A telescopic support module 12 is provided on the back of the mold frame 1. The telescopic support module 12 is used to support the lower surface of the tilting support structure 5 after the lower casting mold 6 and the upper casting mold 10 are closed. A PLC control panel 11 is installed on one side of the surface of the mold frame 1. The output end of the PLC control panel 11 is electrically connected to the input end of the main hydraulic cylinder 2, the auxiliary hydraulic cylinder 8, and the telescopic support module 12, respectively. Two symmetrical guide rods 101 are installed on the left and right inner walls of the mold frame 1. The double column slide table 4 slides with the two guide rods 101. Connecting columns are installed on both sides of the top of the inverted U-shaped hanger 3. The connecting columns are located between the two guide rods 101. The bottom end of the connecting column is fixedly connected to the top end of the double column slide table 4. When the main hydraulic cylinder 2 controls the lifting and moving of components such as the inverted U-shaped hanger 3, the double-column slide 4, and the lower casting mold 6, the double-column slide 4 slides in cooperation with the guide rod 101 in the mold frame 1. The cooperation between the guide rod 101 and the double-column slide 4 improves the sliding accuracy of the lower casting mold 6 on the Z-axis, ensuring that the lower casting mold 6 and the upper casting mold 10 can be stably connected. During the upward movement of the inverted U-shaped hanger 3, double-column slide 4, and lower casting mold 6 controlled by the main hydraulic cylinder 2, the gear self-locking transmission assembly 7 and the tilting support structure 5 will force the lower casting mold 6 to rotate in the opposite direction along the A-axis until the lower casting mold 6 is in a horizontal state and waits to be closed with the upper casting mold 10. During the casting process, the operator can use the PLC control panel 11 to activate the telescopic support module 12 to work. The telescopic support module 12 provides support at the bottom of the lower casting mold 6 to ensure that the lower casting mold 6 and the upper casting mold 10 can be stably closed.

[0019] This embodiment of a multi-umbrella glass insulator manufacturing process, using the aforementioned multi-umbrella glass insulator manufacturing mold, includes the following steps: S101: Check the working status of mold frame 1, PLC control panel 11, main hydraulic cylinder 2 and auxiliary hydraulic cylinder 8 to ensure that all equipment is operating normally. Install the lower casting mold 6 onto the two double column slides 4 and ensure that the lower casting mold 6 is well connected to the double column slides 4. The upper template 9 and upper casting mold 10 also need to be installed in place to ensure that they can be smoothly closed with the lower casting mold 6. S102: The auxiliary hydraulic cylinder 8 and the main hydraulic cylinder 2 control the Z-axis position of components such as the inverted U-shaped hanger 3, the double-column slide 4, the lower casting mold 6, and the tilting support structure 5. The auxiliary hydraulic cylinder 8 controls the Z-axis position of the upper template 9 and the upper casting mold 10 until the lower casting mold 6 and the upper casting mold 10 are moved to the mold closing position. After the lower casting mold 6 and the upper casting mold 10 are closed, the operator connects the feeding casting head 13 to the casting system, and the molten glass material produced by the melting furnace is injected into the mold until the molten glass material evenly fills every corner of the mold. S103: After the casting material is fed, the staff starts the dual-zone water cooler 14 on the lower casting mold 6 and the upper casting mold 10. The dual-zone water cooler 14 begins to cool the mold. S104: After cooling is complete, the main hydraulic cylinder 2 starts to drive the inverted U-shaped hanger 3, the double column slide 4, and the lower casting mold 6 to move down. During the downward movement, the gear self-locking transmission assembly 7 and the tilting support structure 5 are used to make the lower casting mold 6 rotate on the A-axis. The downward movement of the Z-axis of the double column slide 4 and the lower casting mold 6 is converted into the positive rotation movement of the A-axis of the tilting support structure 5 and the lower casting mold 6 through the gear self-locking transmission assembly 7, so as to gradually move the multi-umbrella glass insulators stuck in the lower casting mold 6 toward the workers. S105: After the lower casting mold 6 completes the A-axis rotation, the workers can remove the insulator parts formed on the lower casting mold 6, and clean the upper and lower molds to remove residual materials and impurities, in preparation for the next processing operation.

[0020] Example 2, based on Example 1, is... Figure 5 , Figure 6 , Figure 7 The tilting support structure 5 includes a bearing seat 501 fixed to the top of two double-column slides 4, a rotating shaft 502 rotatably mounted inside the bearing seat 501, and a support frame 503 installed between the opposite ends of the two rotating shafts 502. The dual-zone water cooler 14 and the lower casting mold 6 are sequentially installed on the top of the support frame 503. A horizontal sensor 504 for detecting the tilt angle of the support frame 503 and the lower casting mold 6 is installed on one side of the bottom end of the support frame 503. The output end of the horizontal sensor 504 is electrically connected to the input end of the PLC control panel 11. During the deflection of the lower casting mold 6 and the support frame 503, the horizontal sensor 504 senses their tilt angle. By monitoring the tilt angle of the A-axis of the lower casting mold 6, it is ensured that the mold tilts only within the preset range, thereby making the operation more precise and avoiding unstable mold position or uneven flow of casting material due to excessive tilting. The gear self-locking transmission assembly 7 includes a bearing housing 702 fixed on one side of the outer wall of one of the double column slides 4, a main shaft 703 rotatably mounted inside the bearing housing 702, and a rack 701 mounted on one side of the inner wall of the mold frame 1. A driven gear 704 that meshes with the rack 701 is mounted on one end of the surface of the main shaft 703. The extended line of the central axis of the main shaft 703 is perpendicular to the extended line of the central axis of the rotary shaft 502. A worm gear transmission structure 705 for driving the rotary shaft 502, the support frame 503, and the lower casting mold 6 to rotate is mounted on one end of the main shaft 703 near the rotary shaft 502. The worm gear transmission structure 705 includes a worm fixed on the other end of the main shaft 703 and a worm wheel fixed on one end of the surface of the rotary shaft 502. The worm wheel and the worm mesh with each other. The worm gear transmission structure 705 drives the rotating shaft 502 in the tilting support structure 5 to rotate. The bearing seat 501 provides rotational support for the rotating shaft 502. The rotating shaft 502 then drives the support frame 503 to rotate along the A-axis, causing the lower casting mold 6 to face the workers. After the lower casting mold 6 and upper casting mold 10 complete the casting and forming of the workpiece, the main hydraulic cylinder 2 drives the inverted U-shaped hanger 3, the double-column slide 4, the lower casting mold 6, and the tilting support structure 5 to move downwards. During this process, one end of the main shaft 703 will contact and mesh with the driven gear 704. At this time, the driven gear 704 and the main shaft 703 will start to drive the main shaft 703 to rotate. The main shaft 703 drives the tilting support structure 5 and the lower casting mold 6 to rotate along the A-axis through the worm gear transmission structure 705, so as to cause the lower casting mold 6 and the multi-umbrella glass insulators retained on the lower casting mold 6 to move downwards. Facing the workers, allowing them to perform material unloading operations; when the main hydraulic cylinder 2 stops, the self-locking function of the worm gear transmission structure 705 keeps the tilting support structure 5 and the lower casting mold 6 at the set angle and prevents them from falling back due to gravity or other external forces, thus reducing the occurrence of accidents. At the same time, the worm gear transmission structure 705 can achieve a large reduction ratio, which means that the input speed can be effectively reduced, thereby increasing the output torque and enabling tilting at a lower speed. This ensures that the operator can better control the tilting angle of the mold and avoid material spillage or mold damage due to excessive speed of operation. The lower casting mold 6 and the upper casting mold 10 are provided with multiple umbrella skirt cavities for forming multi-umbrella glass insulators. The multiple umbrella skirt cavities share a single injection channel, so that the lower casting mold 6 and the upper casting mold 10 can form multiple multi-umbrella glass insulators in the same casting time, thereby increasing the output per unit time of the mold. The dual-zone water cooler 14 includes a hollow sheet metal frame 1401 fixed to the top of the support frame 503, S-shaped water cooling pipes 1402 on both sides inside the hollow sheet metal frame 1401, and several heat dissipation fins 1403 evenly installed on the outer circumference of the S-shaped water cooling pipes 1402. The lower casting mold 6 is fixed to the top of the hollow sheet metal frame 1401. During the mold cooling stage, the inlet of the S-shaped water cooling pipe 1402 is connected to the coolant supply end, and the outlet of the S-shaped water cooling pipe 1402 is connected to the coolant collection end or recovery end, such as a water tank. The coolant flows in the S-shaped water cooling pipe 1402 and exchanges heat with the mold through the heat dissipation fins 1403 to reduce the heat of the mold and help the mold and the molten glass material in the mold cool and form.

[0021] Example 3, based on Example 2, by Figure 8The telescopic support module 12 includes two columns 1201 fixed to the back of the mold frame 1, right-angle cylinder seats 1202 fixed close to the outer wall of the two columns 1201, and a support platform 1204 slidably mounted on the bottom of the right-angle cylinder seats 1202. A Y-axis hydraulic cylinder 1203 for moving the support platform 1204 along the Y-axis is installed at the bottom of one of the right-angle cylinder seats 1202. After the Y-axis hydraulic cylinder 1203 pushes the support platform 1204 to move along the Y-axis, the upper surface of the support platform 1204 contacts the lower surface of the support frame 503. When the casting mold 6 is pulled upward and horizontal by the main hydraulic cylinder 2, the inverted U-shaped hanger 3, and the double-column slide 4, the operator... The Y-axis hydraulic cylinder 1203 in the telescopic support module 12 is activated via the PLC control panel 11. The Y-axis hydraulic cylinder 1203 drives the support platform 1204 to move towards the lower casting mold 6 until the upper surface of the support platform 1204 contacts the lower surface of the support frame 503. The extended support platform 1204 supports the tilting support structure 5 and the lower casting mold 6. By providing uniform support, the displacement and shaking of the lower casting mold 6 during the casting process can be effectively reduced. When the lower casting mold 6 and the upper casting mold 10 are opened, the support platform 1204 must be reset to avoid obstructing the tilting support structure 5 and the lower casting mold 6.

[0022] In this embodiment, during use, the operator first checks the working status of the mold frame 1, PLC control panel 11, main hydraulic cylinder 2, and auxiliary hydraulic cylinder 8 to ensure all equipment is operating normally. In particular, the oil level and pressure of the hydraulic system must be within the specified range to ensure the normal operation of the hydraulic cylinders. Then, the lower casting mold 6 is installed onto the two double-column slides 4, ensuring a good connection. At this time, the upper template 9 and upper casting mold 10 also need to be installed to ensure they can smoothly close with the lower casting mold 6. After the upper and lower molds are installed and debugged, the operator uses the PLC control panel... 11. Start the main hydraulic cylinder 2 and auxiliary hydraulic cylinder 8. The main hydraulic cylinder 2 controls the Z-axis position of components such as the inverted U-shaped hanger 3, double-column slide 4, lower casting mold 6, and tilting support structure 5, while the auxiliary hydraulic cylinder 8 controls the Z-axis position of the upper template 9 and upper casting mold 10, until the lower casting mold 6 and upper casting mold 10 are moved to the mold closing position. The operator needs to ensure the alignment accuracy of the lower casting mold 6 and upper casting mold 10 to avoid material leakage during the casting process. Once the lower casting mold 6 and upper casting mold 10 are closed, the operator connects the feeding casting head 13 to the casting system, and the molten glass produced by the furnace... Material is injected into the mold until the molten glass material evenly fills every corner of the mold. After the casting is completed, the operator needs to activate the dual-zone water cooler 14 on the lower casting mold 6 and the upper casting mold 10. The dual-zone water cooler 14 begins to cool the mold. After cooling is complete, the operator releases the pressure of the main hydraulic cylinder 2, which then drives the inverted U-shaped hanger 3, the double-column slide 4, and the lower casting mold 6 to move downwards. During the downward movement, the gear self-locking transmission assembly 7 and the tilting support structure 5 are used to make the lower casting mold 6 rotate on the A-axis. During this process, the downward movement of the lower casting mold 6 on the Z-axis is controlled by the gear self-locking mechanism. The transmission assembly 7 is converted into the tilting support structure 5 and the lower casting mold 6, which rotate in the positive direction of the A-axis. This gradually moves the multi-umbrella-shaped glass insulators remaining in the lower casting mold 6 toward the workers, facilitating subsequent material removal operations. After the lower casting mold 6 completes the rotation of the A-axis, the workers can easily remove the formed insulators. During this process, the workers need to operate carefully to avoid damaging the finished product. After the material removal is completed, the workers check the quality of the finished product to ensure that it meets the design requirements. After the material removal is completed, the workers clean the upper and lower molds to remove residual materials and impurities, and prepare for the next processing operation.
