Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a high-precision automobile parts molding mold. Background Art

[0002] Auto parts stamping dies are dies that process metal or non-metal materials into the shape of auto parts during cold stamping. Its main function is to apply pressure to the material through a press to cause plastic deformation or separation, thereby obtaining auto parts of the desired shape and size.

[0003] In the prior art automotive parts forming dies, initial positioning and clamping are often achieved in a simple way, such as by placing a slot or a movable positioning block. During stamping, as the stamping block makes the middle of the product concave, due to insufficient vertical limit, the two ends of the product lack constraints under the internal stress of the material and rise up. The initial positioning focuses on horizontal fixation, and lacks vertical constraints. For example, the positioning block is only clamped on the side without vertical support. This will cause problems such as product dimensional accuracy deviation and quality consistency. In order to improve it, a high-precision automotive parts forming die is proposed.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] Refer to Figures 1-5 , a high-precision automotive part forming die. This high-precision automotive part forming die is mainly composed of multiple components such as a base 1, a support frame 2, a hydraulic cylinder 3, a stamping block 4, a placement groove 5, a positioning frame 7, and a top plate 18. Each component cooperates with each other to jointly achieve the high-precision forming and processing of automotive parts.

[0027] The base 1, as the basic support part of the die, plays an important role in carrying and fixing other components. It not only provides a stable working platform for the entire die, but also sets key structural spaces such as a moving cavity 8, a transmission cavity 9, and a lifting cavity 14 inside it for installing and accommodating various transmission and driving mechanisms.

[0028] The support frame 2 is installed on the base 1 to support the hydraulic cylinder 3. The hydraulic cylinder 3 is installed on the support frame 2 and is the core power source for driving the stamping block 4 to move up and down. The stamping block 4 presses the automotive parts to be processed placed in the placement groove 5 to form. The stamping block 4 is connected to the hydraulic cylinder 3, and its shape and size are designed according to the specific requirements of the automotive parts to be processed.

[0029] The placement groove 5 is arranged on the upper end surface of the base 1 and is the area for placing the automotive parts to be processed. The shape and size of the placement groove 5 should match the automotive parts to be processed to ensure accurate and stable positioning of the parts during the processing.

[0030] The top plate 18 is located in the receiving groove 19 on the inner bottom wall of the placement groove 5 for... The top plate 18 is connected to the vertical screw rod 15 through the connecting frame 16. The top plate 18 can rise, playing a role in ejecting the parts to be processed and facilitating the removal of the parts. In order to protect the surface of the products to be processed from damage, a protective pad made of rubber material is provided on the surface of the top plate 18 in contact with the products to be processed, which can prevent scratches and other damages to the surface of the parts during the ejection process.

[0031] The horizontal screw rod 11 and the vertical screw rod 15 are respectively rotatably arranged in the moving cavity 8 and the lifting cavity 14 and extend into the transmission cavity 9. They are the key components to realize the precise movement of the positioning frame 7 and the top plate 18 in the mold. The horizontal screw rod 11 is used to drive the positioning frame 7 to move horizontally to fix or release the parts to be processed. The vertical screw rod 15 is used to drive the top plate 18 to lift vertically to realize the ejection function of the parts.

[0032] The transmission mechanism consists of transmission gears 13 installed on the horizontal screw rod 11 and the vertical screw rod 15, and two corresponding transmission gears 13 are meshed with each other. Through this transmission method, when the vertical screw rod 15 rotates under the drive of the power mechanism, it can drive the horizontal screw rod 11 to rotate synchronously through the meshing action of the transmission gears 13, so as to realize the coordinated movement of the positioning frame 7 and the top plate 18. This design ensures the coordination and accuracy of the movements of the two, which helps to improve the precision and stability of the mold during the processing.

[0033] The driving motor 10 is installed in the transmission cavity 9, and its output shaft is connected to the vertical screw rod 15. The driving motor 10 provides power for the movement of the entire mold. When selecting the driving motor 10, parameters such as its rotation speed, torque, and power need to be considered to meet the requirements of the mold under different processing conditions.

[0034] The first limiting mechanism includes a cross bar 12 installed in the transmission cavity 9, and the cross bar 12 slidably penetrates through the positioning frame 7. The function of this limiting mechanism is to limit the positioning frame 7 to move only in the horizontal direction when the horizontal screw rod 11 rotates, and will not rotate or have other unnecessary displacements.

[0035] The second limiting mechanism consists of a vertical rod 17 installed in the lifting cavity 14, and the vertical rod 17 slidably penetrates through the connecting frame 16. Its function is similar to that of the first limiting mechanism, mainly to limit the connecting frame 16 to lift only in the vertical direction when the vertical screw rod 15 rotates, ensuring the stability and perpendicularity of the top plate 18 during the rising and falling processes.

[0036] The opening 6 is provided on the inner bottom wall of the placement groove 5, corresponding to the positioning frame 7 and communicating with the moving cavity 8. The size of the opening 6 should be slightly larger than the size of the positioning frame 7 to ensure that the positioning frame 7 can move smoothly in the opening 6.

[0037] A limiting rod 20 is rotatably arranged on the positioning frame 7 through a mounting plate. The function of the limiting rod 20 is to further position and limit the parts to be processed, preventing the edge part of the parts from warping during the stamping process. The surface of the limiting rod 20 usually needs to be smoothed to reduce the friction with the parts and avoid damaging the surface of the parts.

[0038] When the utility model is in use, in the initial state, the stamping block 4 is at a high position, both positioning frames 7 are at positions to the left of the center of the opening 6 (being to the left means away from the support frame 2), and the top plate 18 is above the storage groove 19 and has a certain distance from the product to be processed (a rectangular flat plate).

[0039] During processing, the rectangular plate is placed in the placement groove 5, and then the drive motor 10 is started. The drive motor 10 directly drives the vertical screw rod 15 to rotate. The vertical screw rod 15 cooperates with the transmission gear 13 to drive the horizontal screw rod 11 to rotate. When the horizontal screw rod 11 rotates, both positioning frames 7 move. Finally, the vertical part of the positioning frame 7 presses and fixes the product to be processed, and the limiting rod 20 on the upper cover of the horizontal part contacts the upper end surface of the product to be processed. Moreover, the rotation of the vertical screw rod 15 drives the top plate 18 to completely enter the storage groove 19. At this time, the hydraulic cylinder 3 is started to drive the stamping block 4 to descend, and the product to be processed can be processed into the shape shown in the figure. Since the middle part of the product to be processed is concave, both of its ends will move towards the middle part. However, due to the setting of the limiting rod 20, its two ends can only move horizontally and will not warp.

[0040] After processing is completed, the drive motor 10 rotates in reverse, and the positioning frame 7 and the limiting rod 20 move until they reach the farthest position of the opening 6, that is, the farthest position of the positioning frame 7 from the support frame 2. At this time, the top plate 18 will rise under the action of the connecting frame 16 and lift the product to be processed, facilitating its taking.

[0041] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the utility model.
