Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber bushing technology, specifically to a processing mold for automotive shock absorber bushings. Background Technology

[0002] With the rapid development of the automotive industry, people's demands for vehicle ride comfort and driving safety are increasing. As a key component of the automotive suspension and shock absorption system, automotive shock absorber bushings play a vital role in buffering, damping, and connecting different parts. Their quality and performance directly affect the overall driving experience and lifespan of the vehicle. Therefore, ensuring the high-quality production of automotive shock absorber bushings has become one of the important tasks in the automotive manufacturing process.

[0003] However, existing automotive shock absorber bushing processing molds often face the thorny problem of difficult demolding. Due to the significant pressure and mold temperature changes during processing, the formed shock absorber bushing tends to adhere tightly to the inside of the lower mold. During the demolding stage, this tight adhesion makes it difficult to remove the bushing smoothly from the mold, resulting in extremely high demolding resistance. This not only severely slows down production efficiency, limiting the output per unit time and failing to meet the large demand for shock absorber bushings on automotive production lines, but also often requires manual demolding with external force. This process can easily cause damage to the product itself, such as surface scratches and structural deformation, and also damages the internal structure of the mold, affecting the mold's precision and service life, increasing production costs and product defect rate. Utility Model Content

[0004] The purpose of this utility model is to provide a processing mold for automotive shock absorber bushings. This processing mold for automotive shock absorber bushings solves the problem that the bushing material is subjected to large pressure and mold temperature changes during processing, and the formed shock absorber bushing is prone to tightly adhering to the inside of the lower mold.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A processing mold for automotive shock absorber bushings includes a body, a telescopic cylinder fixedly mounted on the top of the body, a fixed block fixedly mounted on the bottom of the telescopic cylinder, an upper mold fixedly mounted on the bottom of the fixed block, and a lower mold fixedly mounted inside the body; it also includes a movable component for demolding the formed mold; and a rotating component for striking the surface of the lower mold; the movable component includes: a pressure plate fixedly mounted on the outside of the fixed block, a slide rod penetrating the surface of the body, a support plate fixedly mounted on the top of the slide rod, a connecting rod fixedly mounted on the inner side of the slide rod, a rotating shaft provided on the surface of the connecting rod, the rotating shaft rotatably connected to the inside of the body, the connecting rod slidably connected to the surface of the rotating shaft, a threaded rod fixedly mounted inside the rotating shaft, an annular block threadedly connected to the surface of the threaded rod, a retaining ring rotatably connected to the top of the annular block, and the retaining ring movably connected to the inside of the lower mold.

[0007] Preferably, a fixing spring is fixedly installed on the surface of the slide bar, and the fixing spring is fixedly installed on the inner side of the body.

[0008] Preferably, a movable ring is rotatably connected to the surface of the lower mold, the insert ring is movably connected to the inner wall of the movable ring, a connecting plate is fixedly installed on the outer side of the movable ring, one end of a long rod is movably connected to the top of the connecting plate, and the other end of the long rod is movably connected to the bottom of the support plate.

[0009] Preferably, the rotating assembly includes: a movable block, the movable block being fixedly installed on the back of the fixed block, a rod being fixedly installed on the surface of the movable block, a rotating rod being provided on the surface of the rod, an arc-shaped groove being provided on the surface of the rotating rod, and the rod being slidably connected to the arc-shaped groove provided on the rotating rod.

[0010] Preferably, the rotating rod is rotatably connected to the inner side of the body, a rotating shaft is fixedly installed at the bottom of the rotating rod, and a cam is fixedly installed on the surface of the rotating shaft.

[0011] Preferably, the surface of the rotating shaft is provided with an arc-shaped groove, and the cross-section of the support plate and the connecting plate are both L-shaped.

[0012] Preferably, the lower mold surface has an annular groove, and the body surface has holes.

[0013] By employing the above technical solution, this utility model provides a processing mold for automotive shock absorber bushings. It possesses at least the following beneficial effects:

[0014] (1) By setting up the movable components, after processing, the slide bar will be reset under the action of the fixed spring, so that the connecting rod drives the rotating shaft and the threaded rod to rotate in the opposite direction, and drives the ring block and the insert ring to move upward. When the slide bar moves downward, it will also move downward through the pressure plate against the support plate. At the same time, the connecting plate at the bottom of the long rod drives the movable ring to rotate on the surface of the lower mold. When the movable ring rotates, it will drive the insert ring to rotate inside the lower mold during the upward movement, thereby scraping and cleaning the adhesive part of the molding mold attached to the inside of the lower mold, preventing the pressure and temperature during processing from sticking to the inside of the lower mold, resulting in excessive resistance during demolding, affecting production efficiency, reducing the time required for demolding, increasing the product output per unit time, and speeding up work efficiency.

[0015] (2) By setting the rotating component, when the fixed block moves downward under the action of the telescopic cylinder, it will also drive the movable block and the insert rod to slide in the arc-shaped groove opened on the surface of the rotating rod, thereby driving the rotating rod to rotate. When the rotating rod rotates, it will drive the rotating shaft and the cam to rotate. When the cam rotates, it will strike the surface of the lower mold to generate vibration, preventing the bushing from being difficult to demold. The vibration generated by the cam is transmitted to the lower mold and the bushing in contact with it, reducing the friction between the bushing and the mold, preventing the bushing from getting stuck in the mold during demolding, requiring a lot of manpower or external force to force demolding, reducing the risk of damage to the bushing and mold during demolding, and improving production efficiency.

[0024] 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. Example 1

[0025] A machining mold for automotive shock absorber bushings, such as Figures 1-5 As shown, it includes a body 1, a telescopic cylinder 2 is fixedly installed on the top of the body 1, a fixing block 3 is fixedly installed on the bottom of the telescopic cylinder 2, an upper mold 4 is fixedly installed on the bottom of the fixing block 3, and a lower mold 5 is fixedly installed on the inner side of the body 1.

[0026] It also includes a movable component 6 for demolding the formed mold;

[0027] Rotating component 7 is used to strike the surface of the lower mold 5;

[0028] First, the active component 6 includes: a pressure plate 61, which is fixedly installed on the outside of the fixed block 3; a slide rod 62 extending through the surface of the main body 1; a support plate 63 fixedly installed on the top of the slide rod 62; a connecting rod 64 fixedly installed on the inner side of the slide rod 62; a rotating shaft 65 provided on the surface of the connecting rod 64; the rotating shaft 65 is rotatably connected to the inside of the main body 1; the connecting rod 64 is slidably connected to the surface of the rotating shaft 65; a threaded rod 66 is fixedly installed inside the rotating shaft 65; an annular block 67 is threadedly connected to the surface of the threaded rod 66; an insert ring 68 is rotatably connected to the top of the annular block 67; and the insert ring 68 is movably connected to the inside of the lower mold 5, allowing it to slide inside the lower mold 5 to facilitate contact with the forming mold.

[0029] Secondly, a fixing spring 69 is fixedly installed on the surface of the slide bar 62. The fixing spring 69 is fixedly installed on the inner side of the body 1. The fixing spring 69 on the surface of the slide bar 62 can achieve the effect of resetting after the slide bar 62 has finished sliding.

[0030] Furthermore, a movable ring 610 is rotatably connected to the surface of the lower mold 5, and an insert ring 68 is movably connected to the inner wall of the movable ring 610. A connecting plate 611 is fixedly installed on the outer side of the movable ring 610. One end of a long rod 612 is movably connected to the top of the connecting plate 611, and the other end of the long rod 612 is movably connected to the bottom of the support plate 63. The movable ring 610 can rotate inside the lower mold 5 to prevent the molding die from sticking to the inside of the lower mold 5.

[0031] In this embodiment, with the setting of the movable component 6, after processing, the slide bar 62 will reset under the action of the fixed spring 69, thereby causing the rotating shaft 65 and the threaded rod 66 to rotate in the opposite direction through the connecting rod 64, and causing the annular block 67 and the insert ring 68 to move upward. When the slide bar 62 moves downward, it will also move downward through the pressure plate 61 against the support plate 63. At the same time, the movable ring 610 will rotate on the surface of the lower mold 5 through the connecting plate 611 at the bottom of the long rod 612. When the movable ring 610 rotates, it will cause the insert ring 68 to rotate inside the lower mold 5 during the upward movement, thereby scraping and cleaning the adhesive part of the molding mold attached to the inside of the lower mold 5, preventing the mold from sticking to the inside of the lower mold 5 due to factors such as pressure and temperature during processing, which would cause excessive resistance during demolding, affect production efficiency, reduce the demolding time, increase the product output per unit time, and speed up work efficiency. Example 2

[0032] like Figure 6 As shown, the rotating assembly 7 includes: a movable block 71, which is fixedly installed on the back of the fixed block 3. A rod 72 is fixedly installed on the surface of the movable block 71. A rotating rod 73 is provided on the surface of the rod 72. An arc-shaped groove 730 is provided on the surface of the rotating rod 73. The rod 72 is slidably connected to the arc-shaped groove 730 provided on the rotating rod 73.

[0033] Furthermore, the rotating rod 73 is rotatably connected to the inner side of the main body 1, and a rotating shaft 74 is fixedly installed at the bottom of the rotating rod 73. A cam 75 is fixedly installed on the surface of the rotating shaft 74. The cam 75 on the surface of the rotating shaft 74 can be used to strike and vibrate the surface of the lower mold 5 when the cam 75 rotates.

[0034] Finally, an arc-shaped groove 650 is provided on the surface of the rotating shaft 65. The rotating shaft 65 can be rotated when the connecting rod 64 slides through the arc-shaped groove 650 on the surface of the rotating shaft 65. The cross-section of the support plate 63 and the connecting plate 611 are both L-shaped. The L-shaped support plate 63 and the connecting plate 611 can facilitate the connection with the long rod 612. An annular groove 50 is provided on the surface of the lower mold 5. The annular groove 50 on the surface of the lower mold 5 can facilitate the connection between the movable ring 610 and the insertion ring 68. A hole 10 is provided on the surface of the body 1. The sliding rod 62 can slide on the surface of the body 1 through the hole 10.

[0035] In this embodiment, by setting the rotating component 7, when the fixed block 3 moves downward under the action of the telescopic cylinder 2, it will also drive the movable block 71 and the insert rod 72 to slide at the arc-shaped sliding groove 730 opened on the surface of the rotating rod 73, thereby driving the rotating rod 73 to rotate. When the rotating rod 73 rotates, it will drive the rotating shaft 74 and the cam 75 to rotate. When the cam 75 rotates, it will strike the surface of the lower mold 5 to generate vibration, preventing the bushing from being difficult to demold. The vibration generated by the cam 75 is transmitted to the lower mold 5 and the bushing in contact with it, reducing the friction between the bushing and the mold, preventing the bushing from getting stuck in the mold during demolding, requiring a lot of manpower or external force to forcibly demold, reducing the risk of damage to the bushing and mold during demolding, and improving production efficiency.

[0036] In use, the processing mold for an automotive shock absorber bushing of this utility model can be activated by the telescopic cylinder 2 to move the upper mold 4 downward. When the upper mold 4 moves downward, it moves into the interior of the lower mold 5 for processing. Simultaneously, the movement of the lower mold 5 also moves the pressure plate 61 downward. When the pressure plate 61 moves downward, it abuts against the top of the support plate 63, pushing the support plate 63 to slide along the connecting rod 64 via the slide rod 62 on the surface of the rotating shaft 65, thereby causing the rotating shaft 65 to rotate. When the rotating shaft 65 rotates, it drives the threaded rod 66 to rotate. When the threaded rod 66 rotates, it drives the annular block 67 downward, which in turn drives the insert ring 68 downward. After processing is completed, the slide rod 62 resets under the action of the fixed spring 69, causing the rotating shaft 65 to rotate in the opposite direction via the connecting rod 64. This allows the rotating shaft 65 to drive the annular block 67 and the insert ring 68 downward via the threaded rod 66. 8 moves upward to abut against the bottom of the mold. When the slide bar 62 moves downward, it also abuts against the support plate 63 through the pressure plate 61. At the same time, the connecting plate 611 at the bottom of the long rod 612 drives the movable ring 610 to rotate on the surface of the lower mold 5. When the movable ring 610 rotates, it drives the insert ring 68 to rotate inside the lower mold 5 during the upward movement. This scrapes and cleans the adhesive area of ​​the mold that is attached to the lower mold 5, preventing it from sticking to the inside of the lower mold 5 due to pressure and temperature during processing. This would cause excessive resistance during demolding, making it difficult to remove the molded shock-absorbing bushing from the lower mold 5 smoothly, affecting production efficiency, and even requiring external force to force demolding, which could damage the product or the mold itself. This effectively reduces the degree of adhesion between the bushing and the lower mold 5, making the demolding process smoother and more convenient, reducing the demolding time, increasing product output per unit time, and speeding up work efficiency.

[0037] When the fixed block 3 moves downward under the action of the telescopic cylinder 2, it also drives the movable block 71 to move downward. When the movable block 71 moves downward, it drives the insert rod 72 to slide at the arc-shaped groove 730 opened on the surface of the rotating rod 73, thereby driving the rotating rod 73 to rotate. When the rotating rod 73 rotates, it drives the rotating shaft 74 to rotate. When the rotating shaft 74 rotates, it drives the cam 75 to rotate. Since the cam 75 is made of elastic material, it is not restricted by the lower mold 5. When the cam 75 rotates, it will strike the surface of the lower mold 5 to generate vibration, preventing the bushing from being difficult to demold. The vibration generated by the cam 75 is transmitted to the lower mold 5 and the bushing in contact with it, which can break the tight fit, break the adsorption effect, reduce the friction between the bushing and the mold, and prevent the bushing from getting stuck in the mold during demolding, requiring a lot of manpower or external force to force demolding. This reduces the risk of damage to the bushing and mold during demolding and improves production efficiency.
