Description

Technical Field

[0001] This invention relates to the field of mold technology, specifically to a mold pad with a long service life. Background Technology

[0002] Mold backing plates are used as equipment in mold processing. Their purpose is to check the flatness of the mold and to adjust it. Mold backing plates are relatively small in size and weight, with high precision, weighing approximately 30-50 kg. They are mainly used as processing platforms and backing plates for molds, and can also be used for scribing, checking the flatness of the mold, and adjusting the mold. Metal mold backing plates are divided into: casting molds (non-ferrous metal die casting, steel casting), and forging molds, etc.; non-metallic mold backing plates are divided into: plastic molds and inorganic non-metallic molds. According to the different materials of the mold backing plate itself, molds can be divided into: sand molds, metal molds, vacuum molds, paraffin molds, etc. With the rapid development of polymer plastics, plastic mold backing plates are closely related to people's lives. Plastic mold backing plates can generally be divided into: injection molding molds, extrusion molding molds, gas-assisted molding molds, etc.

[0003] Patent publication number CN211387286U discloses a mold pad, which has a reasonable structure, simple operation, convenient and reliable use, and good clamping effect. It includes: a mold frame, adjusting rods, and a connecting plate. Several adjusting rods are arranged inside the mold frame, and the adjusting rods are connected to the mold frame through the connecting plate. One end of the connecting plate is connected to the adjusting rods through a locking assembly, and the other end of the connecting plate is connected to the mold frame through an adjusting assembly. Several clamping devices are provided on both the mold frame and the adjusting rods, and the clamping devices are connected to the mold frame and adjusting rods through the adjusting assembly. A first template is provided at the bottom of the mold frame, and the first template is connected to the mold frame by screws. A second template is provided at the bottom of the adjusting rods. This improvement to the mold pad has the advantages of reasonable structure, simple operation, convenient and reliable use, and good clamping effect, thus effectively solving the problems and shortcomings raised in this invention.

[0004] The applicant believes that the mold pad has the following drawbacks: the height of the mold pad is fixed, which makes it impossible to adjust the height of the mold pad. As a result, the mold pad can only be used with molds of a certain height, which narrows the scope of application of the mold pad and is therefore defective and needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide a mold pad with a long service life to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a mold pad with a long service life, comprising a mounting plate, a lifting mechanism provided on the top of the mounting plate, a pad body provided on the surface of the lifting mechanism, and a reinforcing plate fixedly connected to the bottom of the pad body. The reinforcing plates are arranged in a plurality of equal intervals. A second support plate is fixedly connected to both sides of the pad body. A clamping mechanism is provided on both sides of the pad body. An adjustment mechanism is provided on the surface of the clamping mechanism. The adjustment mechanisms are all located on the front sides of the pad body. A fixing frame is fixedly connected to both sides of the pad body.

[0007] The lifting mechanism includes threaded rods, each of which is rotatably connected to the four corners of the top of the mounting plate. There are four threaded rods in total. Each of the four threaded rods is rotatably connected to a support frame at its top. Each of the four support frames is fixedly connected to the four corners of the top of the mounting plate. Each of the four threaded rods is fixedly connected to a worm gear at its bottom surface. The worm gear is located on the top of the mounting plate.

[0008] According to the above technical solution, each worm gear surface is engaged with a worm, and each worm gear is rotatably connected to a fixing component on both sides. The fixing components are fixedly connected to the top of the mounting plate. There are two worms, which are symmetrically arranged. With the rotation of the four worm gears, the four threaded rods can be driven to rotate synchronously.

[0009] According to the above technical solution, a dual-axis motor is fixedly connected to the middle of the worm gear surface. The dual-axis motor is fixedly connected to the top of the mounting plate. Under the linkage formed by the pulley group, it can drive the worm gears on both sides to rotate synchronously and drive the four worm wheels to rotate synchronously.

[0010] According to the above technical solution, the adjustment mechanism includes a slide groove, which is connected to both sides of the front side of the pad body. A sliding member is slidably connected in the slide groove, and a positioning plate is fixedly connected between the two sliding members. The number of positioning plates is two, and the two positioning plates are symmetrically arranged in the pad body. By setting the sliding member, the positioning plate is supported.

[0011] According to the above technical solution, the sliding member is internally threaded with a bidirectional lead screw, and a placement frame is rotatably connected to both sides of the bidirectional lead screw. The placement frame is fixedly connected to the top of the pad body. By rotating the bidirectional lead screw, during the rotation of the bidirectional lead screw, the two positioning plates inside the pad body move towards each other or away from each other.

[0012] According to the above technical solution, a guide rod is slidably connected inside the sliding member, and a placement frame is fixedly connected to both sides of the guide rod. A first support plate is fixedly connected to the bottom of the surface of the sliding member. The first support plate is disposed in the pad body. The placement frame can support and fix the threaded rod and the guide rod.

[0013] According to the above technical solution, the first support plate is arranged at equal intervals and is located between the bidirectional lead screw and the guide rod. The first support plate serves to support the mold.

[0014] According to the above technical solution, the clamping mechanism includes a connecting block, which is fixedly connected to the bottom of the sliding surface. A fixing rod is fixedly connected to the top of the connecting block. Two fixing rods are provided, and a horizontal plate is fixedly connected to the top of the two fixing rods. The fixing rods ensure that the spring can perform its function.

[0015] According to the above technical solution, a connecting plate is slidably connected to the surface of the fixed rod, and a spring is provided between the connecting plate and the horizontal plate. The spring is sleeved on the surface of the fixed rod, and under the action of the spring force, it can drive the clamping plate to move downward and clamp and fix the mold.

[0016] According to the above technical solution, a clamping plate is fixedly connected to one side of the connecting plate. The clamping plate is set in the body of the pad plate. The clamping plate can clamp and fix the mold, preventing the mold from shifting during use and ensuring that the mold can be used normally.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. This long-life mold pad, through its lifting mechanism, drives four threaded rods to rotate synchronously under the rotation of four worm gears, thereby raising and lowering the pad body. This allows the height of the pad body to be adjusted according to the height of the operator. Compared with traditional mold pads, it can adapt to molds of different heights, making it more convenient for users.

[0018] 2. This long-life mold pad, through its clamping mechanism, allows the mold to be placed on the surfaces of the first and second support plates. By loosening the clamping plate, the spring force drives the clamping plate to move downwards, clamping and fixing the mold and preventing it from shifting during use, thus ensuring the mold can be used normally.

[0019] 3. This long-life mold pad, through the set adjustment mechanism, rotates a bidirectional lead screw. During the rotation of the bidirectional lead screw, the two positioning plates inside the pad body move towards each other or away from each other, and the sliding part slides on the surface of the guide rod. This allows it to adapt to molds of different sizes, thus improving the application range of this device.

[0020] 4. This long-life mold pad, through the addition of reinforcing plates and fixing frames, can strengthen the pad body and thus improve its service life. Attached Figure Description

[0026] The lifting mechanism 2 includes threaded rods 21, each of which is rotatably connected to the four corners of the top of the mounting plate 1. There are four threaded rods 21, and each of the four threaded rods 21 is rotatably connected to a support frame 22. Each of the four support frames 22 is fixedly connected to the four corners of the top of the mounting plate 1. Each of the four threaded rods 21 is fixedly connected to a worm gear 27 at the bottom of its surface. The worm gear 27 is located at the top of the mounting plate 1.

[0027] Furthermore, each worm gear 27 has a worm 25 meshing on its surface, and each worm gear 27 has a fixing member 24 rotatably connected to both sides. The fixing member 24 is fixedly connected to the top of the mounting plate 1. There are two worms 25, which are symmetrically arranged. When the four worm gears 27 rotate, they can drive the four threaded rods 21 to rotate synchronously.

[0028] Furthermore, a dual-axis motor 26 is fixedly connected to the middle of the surface of the worm 25. The dual-axis motor 26 is fixedly connected to the top of the mounting plate 1. Under the linkage action formed by the pulley group 23, it can drive the worms 25 on both sides to rotate synchronously and drive the four worm wheels 27 to rotate synchronously. Example 2

[0029] See Figure 4-6 Furthermore, based on Embodiment 1, the adjustment mechanism 4 further includes a sliding groove, which is connected to both sides of the front side of the pad body 7. A sliding member 41 is slidably connected in the sliding groove, and a positioning plate 42 is fixedly connected between the two sliding members 41. The number of positioning plates 42 is two, and the two positioning plates 42 are symmetrically arranged in the pad body 7. By setting the sliding member 41, the positioning plate 42 is supported.

[0030] Furthermore, the sliding member 41 is internally threaded with a bidirectional lead screw 46, and both sides of the bidirectional lead screw 46 are rotatably connected to a placement frame 43. The placement frame 43 is fixedly connected to the top of the pad body 7. By rotating the bidirectional lead screw 46, during the rotation of the bidirectional lead screw 46, the two positioning plates 42 inside the pad body 7 move toward each other or toward each other.

[0031] Furthermore, a guide rod 44 is slidably connected inside the sliding member 41, and a placement frame 43 is fixedly connected to both sides of the guide rod 44. A first support plate 45 is fixedly connected to the bottom surface of the positioning plate 42. The first support plate 45 is disposed inside the pad body 7. The placement frame 43 can support and fix the threaded rod 21 and the guide rod 44. The first support plates 45 are arranged at equal intervals and are disposed between the bidirectional screw 46 and the guide rod 44. The first support plates 45 serve to support the mold. Example 3

[0032] See Figure 5 Furthermore, based on Embodiment 1 and Embodiment 2, the clamping mechanism 3 further includes a connecting block 36, which is fixedly connected to the bottom of the surface of the sliding member 41. A fixing rod 32 is fixedly connected to the top of the connecting block 36. Two fixing rods 32 are provided, and a horizontal plate 34 is fixedly connected to the top of the two fixing rods 32. Through the fixed rods 32, the spring 35 can be ensured to perform its function.

[0033] Furthermore, a connecting plate 31 is slidably connected to the surface of the fixing rod 32, and a spring 35 is provided between the connecting plate 31 and the horizontal plate 34. The spring 35 is sleeved on the surface of the fixing rod 32. Under the elastic force of the spring 35, the clamping plate 33 can be driven to move downward and clamp and fix the mold.

[0034] Furthermore, a clamping plate 33 is fixedly connected to one side of the connecting plate 31. The clamping plate 33 is disposed inside the pad body 7. The clamping plate 33 can clamp and fix the mold, preventing the mold from shifting during use and ensuring that the mold can be used normally.

[0035] In actual operation, when this device is used, the dual-axis motor 26 is first started. As the dual-axis motor 26 drives the right-side worm 25 to rotate, the pulley group 23, in conjunction with this, drives the worms 25 on both sides to rotate synchronously, and also drives the four worm wheels 27 to rotate synchronously. At this time, the rotation of the four worm wheels 27 drives the four threaded rods 21 to rotate synchronously, thus driving the pad body 7 to achieve the purpose of lifting and lowering. This allows the height of the pad body 7 to be adjusted according to the height of the worker. Compared to traditional mold pads, it can adapt to molds of different heights, making it more convenient for users. After adjusting the height of the pad body 7, the bidirectional lead screw 46 is then rotated... During the rotation of rod 46, the two positioning plates 42 inside the pad body 7 move toward each other or away from each other, and the sliding member 41 slides on the surface of guide rod 44, thus adapting to molds of different sizes and improving the application range of this device. Then, by pulling the clamping plate 33 upward, the connecting plate 31 slides upward on the surface of the fixing rod 32. Then, by placing the mold on the surface of the first support plate 45 and the second support plate 6, by loosening the clamping plate 33, under the elastic force of the spring 35, the clamping plate 33 can be driven to move downward and clamp and fix the mold, preventing the mold from shifting during use and ensuring that the mold can be used normally.
