Description

Technical Field

[0001] The utility model relates to the technical field of automobile door panels, in particular to an anti-deformation automobile door panel processing die. Background Art

[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to the material at room temperature, causing it to separate or plastically deform, thereby obtaining the desired part. Automobile door products are all irregularly shaped products. Currently, most of them are molded using punching dies. However, existing stamping dies are not easy to demold after stamping, causing the door panel to be pressed against the die, which requires prying open later. Prying open can easily cause the door panel to deform. To this end, we have proposed a deformation-resistant door panel processing die. Utility Model Content

DETAILED DESCRIPTION

[0016] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0017] like Figure 1-2As shown, the utility model is a deformation-proof car door panel processing mold, including a workbench 1, a motor 13 is fixed on the side of the workbench 1, and a screw rod 14 is provided at the output end of the motor 13. A slide plate 15 is threadedly connected to the screw rod 14, and the upper end of the slide plate 15 is connected to the lower mold 22 through a connecting rod 16. By turning on the motor 13 switch, the output end of the motor 13 drives the screw rod 14 to rotate inside the workbench 1, and the rotation of the screw rod 14 drives the slide plate 15 threaded on its surface to move left and right. The lower mold 22 connected to the upper end of the slide plate 15 through the connecting rod 16 can start to move, and the lower mold 22 is slidably connected to the surface of the workbench 1, and the lower mold 22 starts to slide on the surface of the workbench 1. After one stamping is completed, the movement of the slide plate 15 can drive the lower mold 22 to move to the lower end of the second cylinder 4 to perform the discharge work, saving physical effort for workers to move the equipment.

[0018] The interior of the lower mold 22 is rotatably connected to the screw rod 23 through a bearing, and a bevel gear 24 is sleeved on the screw rod 23. The screw 23 is threadedly connected to the movable plate 3. A ejector rod 31 is fixed on the upper end of the movable plate 3. The ejector rod 31 is slidably connected to the lower mold 22. When the door panel is stamped, after the stamping work is completed in the lower mold 22, when the material needs to be taken out of the lower mold 22, the inner side of the lower mold 22 is rotatably connected to the rotating rod 25 through a bearing. A knob 26 is fixed at one end of the rotating rod 25, and a bevel gear 24 is fixed at the other end. By rotating the knob 26, the knob 26 drives the rotating rod 25 to rotate in the lower mold 22, and the rotation of the rotating rod 25 can drive the bevel gear 24 at the port to rotate The bevel gear 24 at the end of the rotating rod 25 is meshed with the bevel gear 24 mounted on the outside of the screw 23. The bevel gear 24 here is meshed with the bevel gear 24 fixedly mounted on the outside of the screw 23, and can thereby drive the bevel gear 24 fixedly mounted on the screw 23 to rotate. The screw 23 rotates in the cavity in the lower mold 22 through the bearing. The rotation of the screw 23 can drive the movable plate 3 connected to its external thread to move upward. The ejecting rod 31 fixedly set at the upper end of the movable plate 3 can penetrate the lower mold 22 and start to slide upward to push the door component stamped in the lower mold 22, so as to avoid directly pulling upward from the top of the door panel during the process of removing the door panel, causing the stamped door panel to be deformed, affecting the effect after stamping.

[0019] The upper end of the workbench 1 is connected to the top plate 12 by a support rod 11, and the top plate 12 is provided with a first cylinder 2 and a second cylinder 4, and the output end of the second cylinder 4 is provided with a box body 41, and the box body 41 is connected to the upper end negative pressure pump 44, and the lower end of the box body 41 is provided with a threaded barrel 42, and the lower end of the threaded barrel 42 is connected to the suction cup 43. After the lower mold 22 is moved to the lower end of the second cylinder 4 by the motor 13, by turning on the switch of the second cylinder 4, the output end of the second cylinder 4 can push the box body 41 to move downward, and adsorb the suction cup 43 on the surface of the door panel. At this time, the switch of the negative pressure pump 44 is turned on, and the negative pressure pump 44 can generate suction at the end of the suction cup 43. After the suction cup 43 is firmly adsorbed on the surface of the door panel, the door panel can be taken out from the lower mold 22 by the second cylinder 4, and at the same time, it cooperates with the ejector rod 31 at the lower end to ensure that the door panel is smoothly demoulded from the lower mold 22, further ensuring that the door panel will not be deformed during the demoulding process.

[0020] In the above scheme, a slide groove 17 is provided on the upper side of the workbench 1, and the connecting rod 16 is slidably connected in the slide groove 17. The provided slide groove 17 can limit the rotation of the connecting rod 16, thereby ensuring that the slide plate 15 moves left and right in the workbench 1.

[0021] In the above scheme, an upper mold 21 is fixed at the lower end of the first cylinder 2. When the lower mold 22 moves to the lower end of the upper mold 21, the first cylinder 2 pushes the upper mold 21 downward by turning on the switch of the first cylinder 2 to start stamping the door panel.

[0022] In the above scheme, a plurality of suction cups 43 are provided at the lower end of the box body 41, and the suction cups 43 are connected to the negative pressure pump 44 through the threaded tube 42 and the box body 41. The suction cups 43 are threadedly connected to the threaded tube 42. When the stamped door panel is adsorbed, because the surface of the door panel is at different levels after stamping, by rotating the suction cups 43, the suction cups 43 and the threaded tube 42 are threadedly connected, and the suction cups 43 can move up and down in the threaded tube 42, and then perform adsorption according to the uneven surface of the door panel. A pressure relief port is provided on the outside of the box body 41. When the door panel needs to be removed after adsorption, the door panel can be taken out from the lower end of the suction cup 43 through the pressure relief port.

[0023] Working principle:

[0024] This anti-deformation door panel processing mold, during specific operation, the door panel to be stamped is placed in the lower mold 22, and the lower mold 22 is moved to the lower end of the upper mold 21 by adjusting the motor 13, and the first cylinder 2 is opened, and the upper mold 21 is moved into the lower mold 22 for stamping. After the stamping is completed, the motor 13 is adjusted again to move the lower mold 22 to the lower end of the second cylinder 4, and the second cylinder 4 is opened. The suction cup 43 at the output end of the second cylinder 4 is adjusted so that the suction cup 43 is adsorbed on the uneven door panel, and the negative pressure pump 44 switch is turned on to make the suction cup 43 adsorb on the surface of the door panel. In the process of starting to move the door panel upward, the knob 26 is turned to rotate the screw 23 in the lower mold 22. The rotation of the screw 23 causes the upper ejector rod 31 to move upward, further demolding the surface material, thereby avoiding deformation of the door panel after demolding, which affects the stamping effect.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
