Description

A mold for producing steel rims for engineering vehicle tires Technical Field

[0001] This utility model relates to the field of tire rim production technology, and in particular to a mold for producing tire rims for engineering vehicles. Background Technology

[0002] With the continuous advancement of infrastructure construction, engineering vehicles are increasingly widely used in fields such as construction, mining, and logistics. As a key component that bears the weight of the vehicle and transmits driving and braking forces, the quality of the tire rims directly affects the safety and stability of the vehicle. To meet the high-intensity, high-load requirements of engineering vehicles, tire rims must possess excellent strength, toughness, and dimensional accuracy. During the production process of tire rims, stamping dies are typically used to stamp them.

[0003] Currently, the molds commonly used in the production of steel rims for engineering vehicle tires have many shortcomings. After the steel rim is formed, it fits tightly to the inner wall of the mold. Traditional molds lack effective demolding auxiliary structures and require external force to force demolding, which not only easily damages the surface of the steel rim but also increases demolding time and reduces production efficiency. Therefore, a mold for the production of steel rims for engineering vehicle tires is proposed. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The purpose of this utility model is to provide a mold for producing steel rims for engineering vehicle tires, which solves the problem mentioned in the background art that the steel rim fits tightly against the inner wall of the mold after molding. Traditional molds lack effective demolding auxiliary structures and require external force to force demolding, which not only easily damages the surface of the steel rim, but also increases demolding time and reduces production efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mold for producing steel rims for engineering vehicle tires, comprising a workbench, a lower mold mounted on one edge of the top surface of the workbench, six placement slots inside the lower mold, a demolding mechanism fixedly connected inside the placement slots, four connecting blocks fixedly connected to the surface of the workbench, a heat dissipation box fixedly connected to one side of one of the connecting blocks, a moving mechanism fixedly connected inside the heat dissipation box, the demolding mechanism comprising a support block fixedly connected to the placement slot, a fixed cylinder fixedly connected to one side of the support block, a torsion spring fixedly connected inside the fixed cylinder, a rotating column fixedly connected to one side of the torsion spring, and a demolding module fixedly connected to one side of the rotating column; the moving mechanism comprising a drive motor fixedly connected to the inside of the heat dissipation box, and a lead screw fixedly connected to the output end of the drive motor.

[0008] As a further embodiment of this utility model, the lower surface of the lower mold is provided with a threaded hole, and the internal thread of the threaded hole is connected to the surface of the lead screw. The lead screw is used to drive the lower mold to move.

[0009] As a further embodiment of this utility model, a limiting hole is provided on one side of the lower mold, and a limiting rod is slidably connected inside the limiting hole. The limiting rod serves to limit the lower mold.

[0010] As a further embodiment of this utility model, extension blocks are fixedly connected to both sides of the surface of the workbench, and a cooling fan is threadedly connected to the top of the extension block. The cooling fan serves to dissipate heat from the surface of the lower mold.

[0011] As a further embodiment of this utility model, four uprights are fixedly connected to the top surface of the workbench, and a top plate is fixedly connected to the top of each upright. The uprights serve to support the top plate.

[0012] As a further embodiment of this utility model, a hydraulic rod is fixedly connected to the top of the top plate, and an upper mold is fixedly connected to the end of the hydraulic rod. The hydraulic rod serves to drive the upper mold to move.

[0014] (III) Beneficial Effects

[0015] This utility model provides a mold for producing steel rims for engineering vehicle tires, which has the following advantages:

[0016] 1. The mold used for producing steel rims for engineering vehicle tires has a demolding mechanism. When the steel plate is pressed and formed, the surface of the steel plate loses pressure. At this time, the torsion spring in the groove at the bottom of the steel plate provides a reverse force to the demolding module, causing the demolding module to rotate inside the mold cavity until the pressed steel plate inside the mold cavity is pushed out of the mold cavity. This achieves the effect of quickly demolding the pressed steel plate and improves the work efficiency of the workers.

[0017] 2. The mold used for producing steel rims for the engineering vehicle tires features a moving mechanism. Traditional lower molds are fixed, which can lead to accidents due to operator error when handling steel plates. Therefore, a lead screw moving mechanism is installed inside the lower mold. Activating a drive motor on one side rotates the lead screw at the output end, causing the lower mold to move left and right along the lead screw surface under a limit rod on one side. This moves the lower mold to a safe position for operation, improving the safety performance of the equipment during use. Attached Figure Description

[0025] The demolding mechanism 3 includes a support block 301 fixedly connected to the inside of the placement groove. A fixed cylinder 302 is fixedly connected to one side of the support block 301. A torsion spring 303 is fixedly connected inside the fixed cylinder 302. A rotating column 304 is fixedly connected to one side of the torsion spring 303. A demolding module 305 is fixedly connected to one side of the rotating column 304.

[0026] The moving mechanism 6 includes a drive motor 601 fixedly connected inside the heat sink 5, and a lead screw 602 is fixedly connected to the output end of the drive motor 601.

[0027] The lower mold 2 has a threaded hole on its lower surface. The internal thread of the threaded hole is connected to the surface of the lead screw 602. The lead screw 602 is used to drive the lower mold 2 to move.

[0028] A limiting hole is provided on one side of the lower mold 2, and a limiting rod 7 is slidably connected inside the limiting hole. The limiting rod 7 serves to limit the lower mold 2.

[0029] Extension blocks 8 are fixedly connected to both sides of the surface of the workbench 1. A cooling fan 9 is threadedly connected to the top of the extension block 8. The cooling fan 9 is used to dissipate heat from the surface of the lower mold 2.

[0030] Four uprights 10 are fixedly connected to the top surface of the workbench 1, and a top plate 11 is fixedly connected to the top of the uprights 10. The uprights 10 serve to support the top plate 11.

[0031] A hydraulic rod 12 is fixedly connected to the top of the top plate 11, and an upper mold 13 is fixedly connected to the end of the hydraulic rod 12. The hydraulic rod 12 is used to drive the upper mold 13 to move.

[0033] In this invention, the working steps of the device are as follows:

[0034] First step: When in use, after the steel plate is pressed and formed, the surface of the steel plate loses pressure. At this time, the torsion spring 303 in the groove at the bottom of the steel plate provides a reverse force to the release module 305, causing the release module 305 to rotate inside the mold cavity until the pressed steel plate inside the mold cavity is pushed out from the mold cavity.

[0035] The second step: During use, since the traditional lower mold 2 is a fixed structure, workers may cause safety accidents due to misoperation when handling and placing steel plates. Therefore, a lead screw 602 moving structure is set inside the lower mold 2. Activating the drive motor 601 on one side causes the lead screw 602 at the output end to rotate, allowing the lower mold 2 to move left and right along the surface of the lead screw 602 under the limit rod 7 on one side, moving the lower mold 2 to a safe position for operation.
