Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, and particularly relates to an automobile parts mold ejection structure. Background Art

[0002] In today's booming automotive industry, the production quality, efficiency, and cost control of auto parts have become key competitive factors for automakers. As the automotive market's demand for personalized, high-performance, and high-quality vehicles continues to grow, the production processes and technologies for auto parts are also constantly improving and innovating.

[0003] In the manufacturing process of automotive parts, mold ejection plays a vital role. Traditional automotive parts mold ejection technology has gradually exposed a series of significant problems and severe challenges in long-term application.

[0004] In the past, the most widely used ejection methods for automotive parts molds mostly relied on simple and direct mechanical structures. For example, components such as push rods and ejector pins directly contacted the molded part and applied thrust to achieve the ejection operation. However, this mechanical ejection mode has many drawbacks that are difficult to ignore:

[0005] First, the frequent and direct contact and friction between mechanical components inevitably leads to severe mechanical wear. This phenomenon not only significantly increases the cost of daily mold maintenance but also significantly shortens the mold's effective service life. Frequent mold failures and repairs, as well as the regular replacement of key components, inevitably disrupt normal production plans and schedules, leading to reduced production efficiency and increased production costs.

[0006] Secondly, due to the lack of effective buffering and control mechanisms during the ejection process, traditional ejection methods often release the ejection force instantly and intensely, generating a tremendous impact force. This impact force can cause irreversible damage to both the mold itself and the newly formed automotive part. For the mold, this can cause deformation, cracks, and even structural damage in key areas. For the formed automotive part, it can cause surface flaws, dimensional deviations, and even hidden damage to the internal structure, seriously affecting product quality and precision, and increasing defective and scrap rates.

[0007] To this end, we have proposed an ejection structure for automotive parts molds. This device not only facilitates the ejection of molded automotive parts, saving time and effort, but also uses magnetic force to achieve non-contact ejection, reducing mechanical wear. Secondly, the elastic moving component reduces the impact force generated during the ejection process, reducing wear and damage to the mold. Utility Model Content

[0008] The purpose of this utility model is to provide an ejection structure of an automobile part mold. The device can not only conveniently eject the formed automobile parts, thus saving time and effort, but also adopts magnetic force to realize non-contact ejection, thereby reducing mechanical wear. Secondly, the elastic moving component can reduce the impact force generated during the ejection process, thereby reducing wear and damage to the mold.

[0013] Furthermore, the moving component includes a threaded rod rotatably arranged inside the hollow base, a threaded sleeve is provided on the threaded rod, the top of the threaded sleeve is connected to the first magnetic block, and one end of the threaded rod passes through the hollow base and is connected to the gear.

[0014] Furthermore, a first sliding groove is provided on the inner wall of the bottom of the hollow base, a first sliding block is provided inside the first sliding groove, and a connecting rod connected to the threaded sleeve is installed on the top of the first sliding block.

[0017] The technical effects achieved by this utility model are:

[0018] When this device is in use, the hydraulic assembly drives the upper mold to move downward, and the upper mold drives the L-shaped connecting plate to move downward, so that the meshing teeth drive the gear to rotate. When the gear rotates, it drives the moving assembly to work, and the moving assembly drives the first magnetic block to move, so that the first magnetic block and the second magnetic block are misaligned, so that there is no repulsive force, and the repulsive force disappears, and the elastic moving assembly works, and the elastic moving assembly drives the movable rod to move downward inside the first movable hole and the second movable hole. At the same time, the movable rod drives the ejection disk into the through hole, so that there is no gap inside the molding cavity, and the upper mold enters the lower mold to form the auto parts. After the auto parts are formed, the hydraulic assembly drives the upper mold to move upward, and at the same time drives the L-shaped connecting plate to move upward, so that the meshing teeth drive the gear to rotate in the opposite direction, so that the moving assembly drives the first magnetic block to move below the second magnetic block. At this time, the first magnetic block and the second magnetic block generate repulsive force, and the second magnetic block drives the movable rod to make the ejection disk extend from the through hole and squeeze the elastic moving assembly, thereby completing the ejection of the workpiece. This device not only facilitates the ejection of molded automotive parts, saving time and effort, but also uses magnetic force to achieve non-contact ejection, reducing mechanical wear. Secondly, the elastic moving component reduces the impact force generated during the ejection process, reducing wear and damage to the mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A first movable hole is provided at the top of the hollow base 1, and a connecting shell 10 corresponding to the position of the first movable hole is provided on the inner wall of the top of the hollow base 1. The top and bottom of the connecting shell 10 are connected, and a second movable hole and a through hole 11 are provided on the inner wall of the bottom of the molding cavity 3. The second movable hole is connected to the first movable hole, and a second slide groove 12 is provided on the four inner walls of the connecting shell 10. An elastic movable component is provided inside each second slide groove 12, and a movable rod 13 located inside the first movable hole and the second movable hole is provided on the elastic movable component. A ejection disk 14 located inside the through hole 11 is provided on the top of the movable rod 13, and a second magnetic block 15 that repels the first magnetic block 4 is provided at the bottom of the movable rod 13.

[0029] The hydraulic assembly includes a hydraulic cylinder 16 provided on the bracket 6 , the telescopic end of the hydraulic cylinder 16 is connected to the upper die 7 , and the upper die 7 is driven to move up and down by the hydraulic cylinder 16 .

[0030] At the same time, the moving component includes a threaded rod 17 rotatably arranged inside the hollow base 1, a threaded sleeve 18 is sleeved on the threaded rod 17, the top of the threaded sleeve 18 is connected to the first magnetic block 4, and one end of the threaded rod 17 passes through the hollow base 1 and is connected to the gear 5.

[0031] When the gear 5 rotates, the threaded rod 17 is driven to rotate, and the rotation of the threaded rod 17 drives the threaded sleeve 18 to move the first magnetic block 4, thereby performing work.

[0032] Furthermore, a first slide groove 19 is opened on the inner wall of the bottom of the hollow base 1, and a first slider 20 is arranged inside the first slide groove 19. A connecting rod 21 connected to the threaded sleeve 18 is installed on the top of the first slider 20.

After the auto parts are formed, the hydraulic assembly drives the upper mold 7 to move upward, and at the same time drives the L-shaped connecting plate 8 to move upward, so that the meshing teeth 9 drive the gear 5 to rotate in the opposite direction, so that the moving assembly drives the first magnetic block 4 to move to the bottom of the second magnetic block 15. At this time, the first magnetic block 4 and the second magnetic block 15 generate a repulsive force, and the second magnetic block 15 drives the movable rod 13 to make the ejection disk 14 extend from the inside of the through hole 11 and squeeze the elastic moving assembly, thereby completing the ejection of the workpiece. This device can not only easily eject the molded auto parts, saving time and effort, but also uses magnetic force to achieve non-contact ejection, reducing mechanical wear.
