This utility model provides a pressure-balanced ball-bearing mold lifter. The sealing ball in the pressure relief device plays a role in maintaining pressure balance. The pressure relief device ensures that the maximum output pressure of all lifters is the same. At the same time, the lubricating oil output through the pressure relief device enters the ball bearing device, lubricating the large and small steel balls in the ball bearing device.

[0004] However, existing ball bearing type mold lifters are not easy to disassemble quickly after use, making it difficult for operators to replace the damaged balls inside the device, which affects the maintenance efficiency of the device and increases the maintenance cost.

[0005] Therefore, in order to address the above problems, there is an urgent need for innovative design based on the existing ball bearing type mold lifter. Utility Model Content

[0006] The purpose of this utility model is to provide a ball bearing type mold lifter to solve the problem mentioned in the background art that it is not convenient to quickly disassemble it after use, making it difficult for operators to replace the damaged balls inside the device, which affects the maintenance and use efficiency of the device and increases the maintenance and use cost of the device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a ball bearing type mold lifter, comprising: a machine body shell, and a second ball bearing disposed in the middle of the machine body shell, wherein a first ball bearing is disposed on the lower side of the second ball bearing;

[0008] Also includes:

[0009] The mounting bracket is installed on the upper side of the outer shell of the machine body, and a buffer assembly is provided on the outer side of the mounting bracket. A positioning plate is provided inside the mounting bracket, and a positioning rod is provided on the inner side of the positioning plate. A connecting block is provided on the upper side of the positioning plate, and a main body lifting assembly is provided at the lower end of the outer shell of the machine body.

[0010] A support frame is installed on the inner side of the positioning rod, and a positioning block is provided on the outer side of the support frame. A cover ring is installed on the upper side of the positioning block, and an operating handle is provided inside the cover ring. A second guide rod passes through the middle of the operating handle, and a locking block is provided at the lower end of the operating handle. A return spring is attached to the inner rear side of the locking block.

[0011] In one possible implementation, the support frame is slidably connected to the positioning rod, and the first balls are evenly spaced inside the support frame.

[0012] In one possible implementation, the connecting block and the locking block are engaged relative to each other, and the connecting blocks are arranged symmetrically about the central axis of the cover ring.

[0013] In one possible implementation, the operating handle is slidably connected to the second guide rod, and the longitudinal section of the second guide rod is an "I" shaped structure.

[0014] In one possible implementation, the main body lifting assembly includes a preset slot formed at the lower end of the outer shell of the machine body, and a base is provided on the outer side of the preset slot, a guide block is provided on the inner side of the base, and a drive motor is installed at the lower end of the base, and a drive rod is connected to the upper side of the drive motor.

[0015] The drive rod is threadedly connected to the outer casing, and the outer casing is slidably connected to the guide block.

[0016] In one possible implementation, the guide block has a "T" shaped cross-section and is symmetrically arranged about the central axis of the base.

[0017] In one possible implementation, the buffer assembly includes a first guide rod mounted on the outside of the mounting bracket, and a buffer spring is mounted on the upper side of the first guide rod;

[0018] The outer casing of the machine body is slidably connected to the first guide rod, and the buffer springs are symmetrically arranged about the central axis of the outer casing.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This ball-bearing mold lifter is easy to disassemble quickly after use, allowing operators to easily replace damaged balls inside the device, avoiding impact on maintenance efficiency and reducing maintenance costs. Simultaneously, the device incorporates an effective buffer and shock-absorbing structure, preventing deformation or damage due to excessive pressure during use, thus extending its service life and providing better performance. Specific details are as follows:

[0020] 1. The mounting frame is guided and damped by the buffer spring in conjunction with the first guide rod, so that the downward pressure generated by the mold is released and damped by the buffer spring, avoiding excessive pressure from affecting the service life of the internal parts of the device and improving the stability of the device in use.

[0021] 2. The drive motor, in conjunction with the drive rod, pushes the outer shell of the machine body to move upward along the guide block, causing the outer shell to push the first and second ball bearings on its upper side to slide up and down. This allows the device to quickly adjust its support height according to the lifting requirements, thereby improving the efficiency of the device.

[0022] 3. By operating the handle in conjunction with the second guide rod, the locking block is moved inward and squeezed, which releases the locking limit of the connecting block that has been squeezed by the inward displacement of the locking block against the reset spring. This makes it easier for the operator to pull the cover ring and support frame out upward, and for maintenance personnel to replace and maintain the second ball and the first ball. This avoids the second ball and the first ball affecting the stability of the device and improves the maintenance and repair efficiency of the device. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 This utility model provides a technical solution: a ball bearing type mold lifter, including a machine body shell 1, a preset groove 2, a base 3, a guide block 4, a drive motor 5, a drive rod 6, a mounting bracket 7, a first guide rod 8, a buffer spring 9, a positioning plate 10, a positioning rod 11, a connecting block 12, a support frame 13, a first ball bearing 14, a second ball bearing 15, a cover ring 16, an operating handle 17, a second guide rod 18, a locking block 19, a reset spring 20, an oil injection hole 21, and a positioning block 22.

[0032] Specifically, such as Figure 2 , Figure 3 and Figure 5As shown, during the use of the device, the mold that needs to be moved is placed on the upper side of the device. At this time, the second ball bearing 15 set in the middle of the device contacts the bottom surface of the template, so that the template pushes the second ball bearing 15 to rotate inside the cover ring 16 and the support frame 13 during the movement. At this time, the first ball bearing 14 set on the lower side of the second ball bearing 15 rotates with the second ball bearing 15, thereby increasing the contact area between the second ball bearing 15 and the device, further reducing the friction between the second ball bearing 15 and the device. At the same time, the second ball bearing 15 contacting the lower side of the template supports it, preventing the template from directly contacting the outer shell 1 and the cover ring 16. The upper surface contacts the template, thereby reducing the contact area of ​​the template device, reducing the friction between the template and the device, improving the template's transport efficiency, and reducing energy consumption. Simultaneously, when the device lifts the template, it is affected by the template's weight. At this time, the template pushes the mounting frame 7 downwards. Due to the sliding connection structure between the mounting frame 7 and the first guide rod 8, the mounting frame 7 is guided and limited by the first guide rod 8 during its downward displacement, preventing positional deviation during its vertical movement and improving the stability of the mounting frame 7's movement. At the same time, during its downward displacement, the mounting frame 7 presses against the buffer set on the upper side of the first guide rod 8. The spring 9 is compressed on the outside of the mounting frame 7. Simultaneously, when the template moves across the upper surface of the device, the compressed spring 9 on the outside of the mounting frame 7 loses its pressure constraint, causing the spring 9 to extend and push the mounting frame 7 upwards along the first guide rod 8. This completes the shock absorption and cushioning protection for the mounting frame 7, preventing excessive pressure from affecting the service life of the internal parts of the device. During use, the drive motor 5 located at the lower end of the base 3 is activated, causing the drive motor 5 to drive the drive rod 6 connected to its upper side to rotate at the lower end of the outer casing 1. The threaded connection between the drive rod 6 and the outer shell 1 allows the drive rod 6 to effectively push the outer shell 1 connected to its upper side to move upward during rotation. Due to the sliding connection between the guide block 4 and the outer shell 1, the guide block 4 slides downward inside the preset groove 2 during the upward movement of the outer shell 1, preventing the outer shell 1 from shifting position during the up-down movement. At this time, the outer shell 1 drives the second ball bearing 15 set on its upper side to move upward to lift and adjust the mold, which makes it easy for the device to quickly adjust the support height of the device according to the lifting requirements, thereby improving the efficiency of the device.

[0033] Specifically, such as Figure 1 , Figure 4 and Figure 6As shown, after the device is used, by pulling the operating handle 17 inward, the locking block 19 connected to its lower end moves inward. Due to the sliding connection between the operating handle 17 and the second guide rod 18, the operating handle 17 and the locking block 19 are guided and limited by the second guide rod 18 during their inward movement, preventing positional displacement. At this time, due to the engaging connection between the locking block 19 and the connecting block 12, the locking block 19, which compresses the return spring 20, releases its engaging limit on the connecting block 12, making it easy for the operator to pull upward and remove the cover ring 16. Simultaneously, due to the sliding connection between the support frame 13 and the positioning rod 11, the operator can easily pull upward and remove the support frame 13, facilitating maintenance personnel to replace and maintain the second ball bearing 15 and the first ball bearing 14, preventing damage to the second ball bearing 15 and the first ball bearing 14 from affecting the device. To ensure the stability of the device, the new support frame 13 is reinstalled inside the mounting frame 7 along the positioning rod 11 and the positioning plate 10. Due to the engaging connection structure between the cover ring 16 and the positioning block 22, the operator can easily fix the cover ring 16 to the upper side of the positioning block 22 and the support frame 13. At the same time, the pull on the operating handle 17 is released, causing the compressed return spring 20 to lose its tension and generate a rebound reaction force. At this time, the return spring 20 pushes the locking block 19 and the operating handle 17 connected to its outer side to move outward along the second guide rod 18 and re-engage with the connecting block 12. At this time, lubricating oil is injected into the interior of the support frame 13 through the oil injection hole 21 provided on the rear side of the cover ring 16. The first ball bearing 14 and the second ball bearing 15 provided inside the support frame 13 are further reduced by the lubricating oil, thereby completing the quick disassembly and maintenance of the device, improving the maintenance and repair efficiency of the device, and reducing the labor intensity of maintenance personnel.
