Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a stamping die for rapid demolding in automotive parts production. Background Technology

[0002] As an important pillar industry of the national economy, the automotive industry is accelerating its transformation towards lightweighting, intelligence, and greening. In the entire automotive production process, parts manufacturing is the fundamental link to ensure the performance and safety of the whole vehicle, and stamping technology, with its advantages of high efficiency and precision forming, undertakes the important task of producing key parts such as engine housings and body panels.

[0003] Currently, most automotive parts stamping dies on the market adopt a traditional fixed stamping depth structure. When producing parts with different specifications and different stamping depth requirements, this type of die often requires frequent replacement of the entire die set. This not only increases the cost of die procurement and the difficulty of warehousing management, but also causes the production line to be shut down for a long time due to frequent die replacement operations, which greatly reduces production efficiency. In the demolding process, traditional stamping dies mostly rely on ejection mechanisms to demold the parts. Common ejection mechanisms, such as mechanical ejector pins or hydraulic ejection devices, have complex structures and many parts. This not only increases the manufacturing and maintenance costs of the die, but also makes it easy for parts to deform or break during the demolding process due to uneven ejection force or improper ejection position, thus reducing the yield rate.

[0004] Therefore, those skilled in the art provide a stamping die for rapid demolding in the production of automotive parts to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the issues of low adaptability and low demolding efficiency in traditional automotive parts stamping dies, this invention provides a stamping die for rapid demolding in automotive parts production, employing the following technical solution:

[0006] A stamping die for rapid demolding in automotive parts production includes a frame. A die cavity is fixedly connected to the top of the frame's inner cavity. A stamping mechanism is fixedly connected to the top of the frame. A demolding mechanism is fixedly connected to one side of the die cavity. The stamping mechanism includes a hydraulic cylinder. The bottom of the hydraulic cylinder is fixedly connected to the frame. A hydraulic rod is slidably connected to the inner cavity of the hydraulic cylinder. A lead screw is movably connected to the inner cavity of the hydraulic rod via a bearing. A sleeve is threadedly connected to the surface of the lead screw. The surface of the sleeve is slidably connected to the hydraulic rod. A punch is fixedly connected to the bottom of the sleeve. A first bevel gear is provided at the top of the sleeve. The inner side of the first bevel gear is fixedly connected to the lead screw. A second bevel gear meshes with one side of the first bevel gear. A rotating rod is fixedly connected to one side of the second bevel gear. The other side of the rotating rod penetrates the inner cavity of the hydraulic rod and extends to the surface of the hydraulic rod.

[0007] Optionally, the demolding mechanism includes a housing, one side of which is fixedly connected to the die, a motor is fixedly connected to the top of the housing cavity, a drive gear is fixedly connected to the output end of the motor, toothed plates mesh on both sides of the drive gear, a load-bearing plate is fixedly connected to one side of the toothed plate through the housing cavity, and both sides of the load-bearing plate are slidably connected to the die.

[0008] Optionally, guide rods are fixedly connected to both sides of the top of the punch, and the surfaces of the guide rods are slidably connected to the frame.

[0009] Optionally, limit plates are provided on both sides of the hydraulic cylinder, and the bottom of the limit plates is fixedly connected to the guide rod.

[0010] Optionally, the hydraulic rod has grooves on both sides of its inner cavity, and the sleeve is slidably connected to the grooves on both sides.

[0011] Optionally, the surface of the hydraulic rod is provided with a graduated groove, and the surface of the sleeve is provided with an indicator.

[0012] Optionally, slots are provided on both sides of the inner cavity of the die, and both sides of the load-bearing plate are slidably connected to the slots.

[0013] Optionally, oil tanks are fixedly connected to both sides of the die, an oil pipe is fixedly connected to the top of the oil tank, an oil outlet is fixedly connected to the top of the oil pipe, and one side of the oil outlet is fixedly connected to the die.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. This utility model's stamping mechanism, through the transmission of a lead screw and bevel gear, enables the punch to adjust the stamping depth as needed, easily meeting the production requirements of automotive parts of different specifications. Whether it is a shallow cavity part or a deep die structure, there is no need to change the mold; the depth can be adjusted simply by operation, significantly improving the adaptability of the production line to diverse products and effectively reducing downtime caused by mold changes. Furthermore, the threaded transmission of the lead screw and sleeve has high precision characteristics, which can avoid part deformation, cracks, or dimensional deviations caused by improper stamping depth.

[0016] 2. The demolding mechanism of this utility model has a fast transmission response speed between the drive gear and the toothed plate, which can complete the removal and repositioning of the load-bearing plate in a short time. Compared with the traditional hydraulic or pneumatic demolding mechanism, this design does not require waiting for the pressure build-up process of hydraulic oil or compressed air, which significantly shortens the demolding time in a single stamping cycle and improves the overall production efficiency of the production line. In addition, the motor drives the drive gear to synchronously drive the toothed plates on both sides to move in opposite directions or in opposite directions, so that the load-bearing plate is subjected to uniform force during demolding, avoiding the displacement or jamming of parts caused by unilateral force. This dual-sided synchronous drive mechanism ensures the smoothness of the demolding process, and is especially suitable for automotive parts with irregular shapes or offset centers of gravity.
