Technical Field
[0001] This utility model relates to the field of positioning support technology, specifically a positioning support for an automobile bumper mold. Background Technology
[0002] In the automotive manufacturing industry, car bumpers are crucial safety and aesthetic components, and their production quality and efficiency are paramount. Positioning supports for car bumper molds are key devices ensuring precise positioning and stable fixation of the molds; their performance directly impacts the bumper's molding quality, production cycle, and mold lifespan. However, current car bumper mold positioning supports commonly suffer from inconvenient positioning and fixation in practical applications, severely hindering the efficiency and precision of car bumper production.
[0003] Existing automotive bumper mold positioning supports mostly use simple positioning pins or blocks to engage with the mold for positioning. This single positioning method often fails to provide comprehensive and high-precision positioning when dealing with complex-shaped automotive bumper molds. For example, for some bumper molds with unique curved surfaces and multiple functional structures, relying solely on a few positioning pins or blocks is insufficient to ensure the mold's positional accuracy in all directions. During mold installation, inaccurate positioning can easily lead to slight displacement deviations between the mold and the support, resulting in quality problems such as dimensional deviations and shape deformations in the produced bumper products, severely impacting the product yield. Furthermore, this single positioning structure is prone to wear and tear over long-term use due to frequent mold loading and unloading and vibrations during production, further reducing positioning accuracy, increasing the frequency of mold adjustments, and raising production costs. Utility Model Content
[0004] The purpose of this invention is to provide a positioning support for automotive bumper molds, addressing the shortcomings of existing automotive bumper mold positioning supports mentioned in the background section. These supports mostly rely on simple positioning pins or blocks for positioning with the mold. This single positioning method often fails to provide comprehensive, high-precision positioning for complex-shaped automotive bumper molds. For example, for bumper molds with unique curved surfaces and multiple functional structures, relying solely on a few positioning pins or blocks is insufficient to ensure the mold's positional accuracy in all directions. During mold installation, inaccurate positioning can easily lead to slight displacement deviations between the mold and the support, resulting in quality problems such as dimensional deviations and shape deformations in the produced bumper products, severely impacting the product yield. Furthermore, this single positioning structure is prone to wear and tear during long-term use due to frequent mold loading and unloading and vibrations during production, further reducing positioning accuracy and increasing the frequency of mold adjustments and production costs.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning support for an automobile bumper mold, comprising a support base, side columns fixedly connected to the four sides of the top of the support base, a mold body disposed at the center of the top of the support base, positioning grooves being provided at the four corners of the top of the support base, positioning blocks fixedly connected to the four sides of the bottom of the mold body, the bottom of the positioning blocks penetrating into the positioning grooves and engaging with the positioning grooves, fixing grooves being provided at the center of the opposite sides of the two positioning blocks disposed on the left and right, and sliding grooves being provided on the opposite sides of the positioning grooves on both sides of the top of the support base. A cylinder is fixedly installed at the center of both sides of the part. A push rod is fixedly connected to the output end of one side of the cylinder. A side fixing seat is fixedly connected to one side of the push rod. A side frame is opened at the center of both sides of the mold body. One side of the side fixing seat extends through the interior of the side frame and is engaged with the side frame. A connecting plate is fixedly connected to the center of the top and bottom of the side fixing seat. A sliding seat is fixedly connected to the bottom of the connecting plate located at the bottom. The bottom of the sliding seat extends through the interior of the sliding groove and is slidably connected to the sliding groove. A fixing post is fixedly connected to the center of one side of the sliding seat. One side of the fixing post extends through the interior of the fixing groove and is engaged with the fixing groove.
[0006] Compared with the prior art, the beneficial effects of this utility model are: The positioning support used in this car bumper mold achieves omnidirectional, high-precision positioning of the mold body through multiple positioning structures. Positioning blocks on the four sides of the bottom of the mold body penetrate into positioning grooves at the four corners of the top of the support base and engage, forming the first level of positioning. This initially determines the mold's position on the horizontal plane from the four corners of the bottom. Simultaneously, a central positioning plate is fixedly connected to the center of the bottom of the mold body. The bottom of the central positioning plate penetrates into the support base and engages, forming the second level of positioning. This further refines the mold's position in the vertical direction and horizontal center. This effectively solves the problem that existing positioning supports, which only use simple positioning pins or blocks, cannot provide omnidirectional, high-precision positioning for complex-shaped molds. For bumper molds with unique curved surfaces and multiple functional structures, this multi-dimensional positioning method ensures the mold's positional accuracy in all directions, avoiding minor displacement deviations between the mold and the support due to inaccurate positioning, thereby significantly reducing production defects. The probability of quality problems such as dimensional deviations and shape deformation in bumper products is significantly reduced, and the product qualification rate is significantly improved. In terms of fixation, this positioning support adopts a double fixing structure to ensure the stable installation of the mold body. The cylinders fixedly installed at the center of both sides of the top of the support base push the push rod at the output end to push the side fixing seat, so that one side of the side fixing seat passes through into the side frame inside the center of both sides of the mold body and locks in place. This is the first layer of fixation, which fixes the mold from both sides to prevent the mold from swaying left and right in the horizontal direction. At the same time, the fixing post on the sliding seat on one side of the side fixing seat passes through into the fixing groove in the center of the opposite side of the positioning block and locks in place, forming the second layer of fixation, which further strengthens the fixation effect of the mold in the horizontal direction. Compared with the single fixing method of existing positioning supports, this double fixing structure can effectively prevent the mold from loosening due to vibration and other factors during production, ensure the stability of the mold on the support, reduce the frequency of mold adjustment, and reduce production costs.

[0011] A center positioning plate 4 is fixedly connected to the center of the bottom of the mold body 3. The bottom of the center positioning plate 4 extends through the interior of the support base 1 and is engaged with the support base 1.
[0012] A limiting block 16 is fixedly connected to the center of the inner wall of the side frame 8. The center of the opposite end of the two side fixing seats 9 set on the left and right is provided with a limiting groove 15. One side of the limiting block 16 extends into the interior of the limiting groove 15 and is engaged with the limiting groove 15.
[0013] Auxiliary slots 17 are provided at the four corners of the outer side frame 8. Auxiliary rods 18 are fixedly connected to the front and rear sides of the connecting plate 10. One side of the four auxiliary rods 18 extends into the interior of the four auxiliary slots 17 and engages with the auxiliary slots 17.
[0014] Support rods 14 are fixedly connected to the top and bottom positions of the sliding groove 7. The support rods 14 are sleeved and slidably connected to the sliding seat 11.
[0015] The support base 1 has a movable groove 21 at the center of one side of the sliding groove 7. A movable plate 22 is slidably connected to one side of the movable groove 21. One side of the movable plate 22 extends into the interior of the sliding groove 7 and is fixedly connected to the other side of the sliding base 11.
[0016] A support groove 23 is provided on one side of the movable plate 22. A support slider 24 is slidably connected to one side of the support groove 23. A fixing rod 25 is fixedly connected to the center of one side of the support slider 24. The side of the fixing rod 25 away from the support slider 24 passes through the interior of the movable groove 21 and is fixedly connected to the center of the inner wall of the movable groove 21. A return spring 26 is sleeved on the surface of the fixing rod 25. The two sides of the return spring 26 are fixedly connected to the inner wall of the movable groove 21 and the movable plate 22, respectively.
[0017] Working principle: The mold body 3 is placed at the top center of the support base 1. The positioning blocks 6 on the four sides of the bottom of the mold body 3 move downwards, precisely penetrating into the positioning grooves 5 at the four corners of the top of the support base 1 and engaging. This process utilizes the cooperation between the positioning blocks 6 and the positioning grooves 5 to initially determine the position of the mold on the horizontal plane from the four corners of the bottom of the mold, laying the foundation for subsequent precise positioning. At the same time, the center positioning plate 4, which is fixedly connected to the center of the bottom of the mold body 3, is inserted downwards into the support base 1 and engages. The engagement between the center positioning plate 4 and the support base 1 forms a second positioning, further refining the position of the mold in the vertical direction and the horizontal center. Through these two positioning methods, the initial precise positioning of the mold body 3 is achieved. To meet the positioning requirements of complex-shaped molds, cylinders 19, fixedly mounted on the center of both sides of the top of the support base 1, begin to operate. The output end of one side of the cylinder 19 pushes the push rod 20 towards the mold body 3. The push rod 20 drives the side fixing seat 9 to move closer to the side frame 8 at the center of both sides of the mold body 3. Connecting plates 10 are fixedly connected to the center of the top and bottom of the side fixing seat 9. A sliding seat 11 is fixedly connected to the bottom of the connecting plate 10 located at the bottom. The bottom of the sliding seat 11 extends through the sliding groove 7 opened on both sides of the top of the support base 1. Support rods 14 are fixedly connected to the top and bottom positions of the sliding groove 7. During the movement of the side fixing seat 9, the support rods 14 are sleeved with and slide against the sliding seat 11. The side fixing seat 9 provides stable support and guidance for the sliding of the sliding seat 11, ensuring that it can move smoothly and accurately towards the side frame 8. The side fixing seat 9 gradually penetrates into the interior of the side frame 8 at the center of both sides of the mold body 3 and engages with it. This is the first layer of fixation for the mold body 3, preventing the mold from swaying left and right in the horizontal direction. Simultaneously, as the side fixing seat 9 engages with the side frame 8, the limiting block 16, fixedly connected to the center of the inner wall of the side frame 8, penetrates into the limiting groove 15 opened at the center of the opposite end of the side fixing seat 9 and engages with it. The engagement of the limiting block 16 and the limiting groove 15 provides precise guidance and limitation, ensuring that the side fixing seat 9 can accurately engage with the designated position of the side frame 8, further improving the stability. To ensure positioning accuracy, during the movement of the side fixing seat 9, the auxiliary rods 18 fixedly connected to the front and rear sides of the connecting plate 10 move accordingly. Auxiliary slots 17 are provided at the four corners of the outer side frame 8. One side of the auxiliary rod 18 passes through the auxiliary slot 17 and engages, forming an auxiliary positioning structure. This provides clear guidance for mold installation, making installation more convenient and accurate. After the side fixing seat 9 is engaged, the fixing column 13 fixedly connected to the center of the sliding seat 11 passes through the fixing slot 12 opened at the center of the opposite side of the positioning block 6 and engages, forming a second layer of fixation. This further strengthens the fixation effect of the mold in the horizontal direction and effectively prevents the mold from loosening due to vibration and other factors during production.
[0018] In summary, the positioning support for this car bumper mold achieves omnidirectional, high-precision positioning of the mold body 3 through multiple positioning structures. Positioning blocks 6 on the four sides of the bottom of the mold body 3 penetrate into and engage with positioning grooves 5 at the four corners of the top of the support base 1, forming the first level of positioning. This initially determines the mold's position on the horizontal plane from the four corners of the bottom. Simultaneously, a central positioning plate 4 is fixedly connected to the center of the bottom of the mold body 3. The bottom of the central positioning plate 4 penetrates into and engages with the support base 1, forming the second level of positioning. This further refines the mold's position in the vertical direction and horizontal center, effectively solving the problem that existing positioning supports using only simple positioning pins or blocks 6 cannot provide omnidirectional, high-precision positioning for complex-shaped molds. For bumper molds with unique curved surfaces and multiple functional structures, this multi-dimensional positioning method ensures the mold's positional accuracy in all directions, avoiding minor displacement deviations between the mold and the support due to inaccurate positioning, thereby significantly reducing the production of bumper molds with poor positioning accuracy. The probability of quality problems such as dimensional deviation and shape deformation in the lever product is significantly reduced, and the product qualification rate is significantly improved. In terms of fixation, this positioning support adopts a double fixing structure to ensure the stable installation of the mold body 3. The cylinder 19 fixedly installed on the center of both sides of the top of the support base 1 pushes the side fixing seat 9 with the push rod 20 at its output end, so that one side of the side fixing seat 9 passes through into the inside of the side frame 8 at the center of both sides of the mold body 3 and is locked. This is the first layer of fixation, which fixes the mold from both sides to prevent the mold from swaying left and right in the horizontal direction. At the same time, the fixing post 13 on the sliding seat 11 on one side of the side fixing seat 9 passes through into the fixing groove 12 at the center of the opposite side of the positioning block 6 and is locked, forming the second layer of fixation, which further strengthens the fixation effect of the mold in the horizontal direction. Compared with the single fixing method of the existing positioning support, this double fixing structure can effectively prevent the mold from loosening due to vibration and other factors during the production process, ensure the stability of the mold on the support, reduce the frequency of mold adjustment, and reduce production costs.
