Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically a demolding mechanism for an automotive mold stamping machine. Background Technology

[0002] In the automotive manufacturing industry, the production of automotive molds plays a crucial role in the quality and performance of the entire vehicle. The most important component of automotive molds is the body panel mold, which is mostly a cold stamping die. However, in a broader sense, automotive molds encompass all types of molds used to manufacture automotive parts, such as stamping dies, injection molds, forging dies, casting wax models, and glass molds. In the automotive mold production process, the stamping press is an indispensable key piece of equipment, and after stamping, the demolding mechanism becomes a crucial link in achieving efficient production.

[0003] In the demolding mechanism for stamping completion, authorization announcement number CN217964480U proposes a demolding mechanism for a stamping machine, including a mounting base and a movable lever module. The mounting base is provided with the movable lever module. The mounting base includes a first mounting rod and a second mounting rod. The movable lever module includes a first connecting rod and a second connecting rod. The bottom ends of the first connecting rod and the second connecting rod are respectively provided with a rotating shaft. This device can push the product away from the stamping area to achieve demolding after stamping through the multi-link structure.

[0004] While the aforementioned demolding mechanism can achieve demolding and unloading, it is only suitable for relatively regular-shaped workpieces that can slide along the stamping die. It is difficult to apply to irregularly shaped workpieces. In the stamping of automotive parts, due to the large number and diverse shapes of automotive parts, most parts are difficult to slide along the stamping die. Therefore, this type of demolding mechanism is not suitable for the demolding of automotive parts. To address the above problems, we provide a demolding mechanism for automotive mold stamping machines to solve the aforementioned issues. Utility Model Content

[0026] 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.

[0027] Please see Figures 1-5 In this embodiment of the present invention, a demolding mechanism for an automotive mold stamping machine includes a base plate 1. A bottom connecting sleeve 2 is fixedly connected to one side of the upper surface of the base plate 1. A rotating column 16 is rotatably connected inside the bottom connecting sleeve 2. A rectangular hollow column 11 is fixedly connected to the upper end of the rotating column 16. A driving assembly for driving the rotating column 16 to rotate is provided at the lower end of the base plate 1. The driving assembly includes a gear 18, which is fixedly connected to the position where the lower end of the rotating column 16 protrudes from the base plate 1. An L-shaped limiting slide plate 20 is fixedly connected to the lower surface of the base plate 1 near the gear 18. A rack 19 is slidably connected inside the L-shaped limiting slide plate 20. The rack 19 meshes with the gear 18. One end of the base plate 1 is fixedly connected to a third cylinder 13 for driving the rack 19 to slide within the L-shaped limiting slide plate 20. When the rectangular hollow column 11 is driven to rotate, the output end of the third cylinder 13 drives the rack 19 to move along the L-shaped limiting slide plate 20. The movement of the L-shaped limiting slide plate 20 can drive the gear 18 to rotate. The rotation of the gear 18 drives the rectangular hollow column 11 to rotate 180 degrees. The rectangular hollow column 11 rotates 180 degrees each time, and the rectangular hollow column 11 will alternate between forward and reverse rotation of 180 degrees under the reciprocating motion of the rack 19, thereby avoiding the problem of entanglement of connected lines and pipes.

[0028] A mounting sleeve 17 is slidably connected to the rectangular hollow column 11. T-shaped rails 6 are fixedly connected to both sides of the mounting sleeve 17. A lifting assembly for adjusting the height of the mounting sleeve 17 is provided inside the rectangular hollow column 11. The lifting assembly includes a sliding vertical groove 7, which is located on both sides of the rectangular hollow column 11. An inner slider 21 is fixedly connected inside the mounting sleeve 17. The inner slider 21 is slidably connected to the inner wall of the rectangular hollow column 11 and the sliding vertical groove 7. An electric push rod 22 for pushing the mounting sleeve 17 up and down is provided at the lower end of the rectangular hollow column 11. When the height of the mounting sleeve 17 needs to be adjusted, the output end of the electric push rod 22 drives the inner slider 21 to move. The movement of the inner slider 21 drives the mounting sleeve 17 to move up and down accordingly, thereby achieving the adjustment of the height of the mounting sleeve 17.

[0029] Both sides of the mounting sleeve 17 are slidably connected to U-shaped slide plates 5, which are slidably connected to T-shaped rails 6 on both sides. The mounting sleeve 17 is provided with an action component for driving the U-shaped slide plates 5 to move up and down. The action component includes a first cylinder 9, which is fixedly connected to the rectangular hollow column 11 above the U-shaped slide plates 5. The output end of the first cylinder 9 is fixedly connected to the U-shaped slide plates 5. The action of the output end of the first cylinder 9 can drive the U-shaped slide plates 5 to move up and down. The up and down movement of the U-shaped slide plates 5 can drive the gripping mechanism to move up and down accordingly, so as to grip the stamped product.

[0030] Each U-shaped sliding plate 5 is fixedly connected to a U-shaped fixing frame 10, and the U-shaped fixing frame 10 is provided with a gripping mechanism for demolding the stamped product; the gripping mechanism includes a U-shaped sliding frame 14, which is slidably connected to the end of the U-shaped fixing frame 10. A rectangular sliding ring is fixedly connected to the end of the U-shaped sliding frame 14 near the U-shaped sliding plate 5, and the rectangular sliding ring is slidably connected to the U-shaped fixing frame 10. A material-receiving plate 4 is fixedly connected to the end of the U-shaped sliding frame 14 away from the U-shaped sliding plate 5, and the material-receiving plate 4 has several strip-shaped holes 1. 5. The strip-shaped hole 15 is provided with a plurality of gripping elements 8. When gripping the stamped product, the second cylinder 12 drives the U-shaped sliding frame 14 to move, so that the material taking plate 4 extends into the stamping mold. Then the first cylinder 9 drives the U-shaped sliding plate 5 to move downward so that the gripping elements 8 press on the product. Then the product is gripped by the gripping elements 8. After gripping, the first cylinder 9 drives the U-shaped sliding plate 5 to reset up and down. After resetting, the product will be lifted and demolded. Then the second cylinder 12 drives the U-shaped sliding frame 14 to reset, so that the gripped product can be taken out from the stamping equipment.

[0031] The gripper 8 includes a hollow threaded tube 81, with a vacuum suction cup 83 installed at the lower end of the hollow threaded tube 81 and an air inlet fixedly connected to the upper end of the hollow threaded tube 81. Two nuts 82 are threaded onto the hollow threaded tube 81. The position of the hollow threaded tube 81 can be fixed or adjusted by the two nuts 82. During installation, one nut 82 is first removed, and then the hollow threaded tube 81 is inserted into the strip hole 15 at the desired position and slid to adjust the position. After the position is determined, the removed nut 82 is screwed onto the hollow threaded tube 81, and then the nut 82 is rotated so that the two nuts 82 are clamped on the material-grabbing plate 4, thereby fixing the position of the hollow threaded tube 81.

[0032] A receiving box 3 for collecting materials is placed on the other side of the upper end face of the base plate 1. Handles are fixedly connected to both sides of the receiving box 3. Support feet are fixedly connected to the four corners of the lower end face of the base plate 1. The products can be collected through the receiving box 3. The receiving box 3 is placed on the base plate 1. After it is full, the worker can take away the empty receiving box 3.

[0033] The working principle of this utility model is as follows: During operation, the base plate 1 is placed on one side of the stamping machine, maintaining a suitable distance. Then, the inner slider 21 is pushed by the electric push rod 22 to adjust the height of the mounting sleeve 17. The distance is such that the material-receiving plate 4 can extend into the material-receiving position of the stamping machine. Then, the position of the gripper 8 is adjusted accordingly according to the product shape. During material receivable, the second cylinder 12 drives the U-shaped sliding frame 14 to move, so that the material-receiving plate 4 extends into the stamping die. Then, the first cylinder 9 drives the U-shaped sliding plate 5 to move downward, so that the gripper 8 presses onto the product. Then, the product is gripped by the gripper 8. After the product is gripped, the first cylinder 9 drives the U-shaped slide plate 5 to reset up and down. After the product is reset, it will be lifted and demolded. Then the second cylinder 12 drives the U-shaped sliding frame 14 to reset, so that the gripped product can be taken out of the stamping equipment. Then the output end of the third cylinder 13 drives the rack 19 to move along the L-shaped limiting slide plate 20. The movement of the L-shaped limiting slide plate 20 can drive the gear 18 to rotate. The rotation of the gear 18 drives the rectangular hollow column 11 to rotate 180 degrees, and the positions of the two picking plates 4 are exchanged. After the product is rotated to the top of the receiving box 3, the gripper 8 releases the product, and the product falls into the receiving box 3 for collection.

[0034] It should also be noted that the vacuum suction cup 83, the first cylinder 9, the second cylinder 12, the third cylinder 13 and the electric push rod 22 in this application are all conventional components in this technical field. Their specific working and control principles as well as pipeline or circuit connections are technologies known to those skilled in the art, and will not be elaborated upon here.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
