Description

Technical Field

[0001] The utility model relates to the technical field of automobile stamping dies, in particular to a stamping die for automobile parts. Background Art

[0002] Auto parts are the various units that constitute the overall auto parts processing and the products that serve the auto parts processing. Auto parts need to be processed using stamping dies during production. Stamping dies are a pressure processing method that applies pressure to the materials of auto parts to cause them to separate or plastically deform, thereby obtaining the required parts.

[0003] However, some small parts molds still use manual methods to manually load the plates and manually remove the stamped parts after stamping. This method requires workers to stretch their hands between the upper and lower molds to operate. This operation not only makes the degree of automation of the mold low, but also if the mold is accidentally closed during the process of taking and placing materials, it will cause serious damage to the operator's hands. Therefore, there are certain safety hazards in the stamping mold, and there is still room for improvement. Utility Model Content

A concave die cavity 105 is provided on the concave plate 104 for forming the workpiece to be stamped. A through hole communicating with the second cavity 1041 is provided in the concave die cavity 105.

[0029] The die fixing plate 103 is installed on the backing plate 102 and is used to fix the die plate 104. The upper surface of the die fixing plate 103 is flush with the upper surface of the support plate 501, and a guide groove 1031 is provided on the die fixing plate 103. The length direction of the guide groove 1031 is parallel to the length direction of the push plate 503.

[0030] The positioning groove 106 is formed on the concave mold plate 104 and is located at the periphery of the concave mold cavity 105, and is used to position the workpiece to be stamped pushed by the loading and unloading assembly 5 on the stamping station;

[0031] Guide pillar 107, used to guide the stamping work;

[0032] The upper mold part 2 comprises:

[0033] The upper die base 201 is located directly above the lower die base 101;

[0034] The punch 204 is mounted on the upper die base 201 and is used to cooperate with the die cavity 105 to perform punching and forming on the workpiece to be punched;

[0035] The punch fixing plate 202 is mounted on the upper die base 201 and is used to fix the punch 204;

[0036] A pressure rod 206, mounted on the punch fixing plate 202, for driving the demoulding assembly 3;

[0037] A guide sleeve 203 is mounted on the upper die base 201 and is used to cooperate with the guide post 107 for guidance;

[0038] The die handle 205 is mounted on the upper die base 201 and is used to mount the upper die part 2 on the actuator of the press and transmit the punching force;

[0039] A stamping die for automobile parts, further comprising:

[0040] A demoulding assembly 3 is provided in the lower die portion 1 and is used to eject the stamped part from the die after stamping;

[0041] The demoulding assembly 3 comprises:

[0042] The sliding plate 301 is slidably installed in the first cavity 1021 and the second cavity 1041;

[0043] The push rod 302 is installed on the sliding plate 301, and is used to dock with the pressure rod 206 and transmit the thrust from the pressure rod 206. The upper surface of the concave template 104 is located directly below the pressure rod 206 and is vertically provided with a plug hole, which is connected to the second cavity 1041, and the push rod 302 is located in the plug hole;

[0044] The ejector rod 303 is mounted on the sliding plate 301 and extends into the female mold cavity 105 through the through hole in the female mold cavity 105;

[0045] A return spring 304 is installed between the sliding plate 301 and the lower die base 101, and is used to return the sliding plate 301, the push rod 302 and the ejector rod 303 to the original position;

[0046] like Figure 1 , Figure 4 and Figure 5 As shown, when the press drives the mold to close the mold for stamping, the lower mold part 1 moves down and during the process of stamping the workpiece to be stamped, the pressure rod 206 will also be inserted into the socket and press the push rod 302 downward, so as to push the sliding plate 301 and the ejector rod 303 to slide downward. In this process, the return spring 304 will also be compressed until the stamping is completed, and the upper end of the ejector rod 303 is just flush with the bottom wall of the die cavity 105. Then the press controls the lower mold part 1 to move up for mold opening. In this process, the return spring 304 rebounds and gradually pushes the sliding plate 301, the push rod 302 and the ejector rod 303 back to their original positions. At this time, the upper ends of the ejector rod 303 and the push rod 302 are flush with the bottom wall of the positioning groove 106. In this process, the stamping part in the die cavity 105 can be ejected upward by resetting the ejector rod 303, thereby completing the automatic demolding of the stamping part.

[0047] The loading and unloading assembly 5 is arranged on the lower die part 1 and is used to push the stamped parts out of the die after stamping and to transport the workpieces to be stamped to the stamping station;

[0048] The linkage assembly 4 is provided between the lower die portion 1 and the upper die portion 2 and is used to drive the loading and unloading assembly 5;

[0049] The linkage component 4 includes:

[0050] The mounting frame 401 is mounted on the lower die base 101 at a position outside the pad 102;

[0051] The transmission shaft 402 is rotatably mounted on the mounting frame 401;

[0052] A first gear 403 is mounted on one end of the transmission shaft 402;

[0053] A second gear 404 is mounted on the other end of the transmission shaft 402;

[0054] The first rack 405 is slidably mounted inside the guide groove 1031 and meshes with the second gear 404, and the first rack 405 is connected to the connecting rod 502;

[0055] A guide sleeve 406 is sleeved on the outside of the first rack 405 and is used to guide and stabilize the sliding of the first rack 405;

[0056] The second rack 407 is mounted on the upper mold base 201 and is perpendicular to the first rack 405. When the mold is in the closed state, the second rack 407 is not meshed with the first gear 403. When the mold is opened for a certain distance, the second rack 407 starts to mesh with the first gear 403 and drives the first gear 403 to rotate.

[0057] The loading and unloading assembly 5 comprises:

[0058] A support plate 501 is mounted on the lower mold part 1;

[0059] The push plate 503 is L-shaped and slidably mounted on the support plate 501, and is used to push the stamping part ejected from the demoulding assembly 3 out of the mold;

[0060] A loading trough 504 is provided on the push plate 503 along the thickness direction. The shape of the loading trough 504 matches the workpiece to be punched and is used to temporarily store the workpiece to be punched and push the workpiece to be punched to the punching station.

[0061] The connecting rod 502 is installed on the push plate 503 and is used to connect the push plate 503 with the linkage assembly 4:

[0062] like Figures 1 to 4As shown, after the mold is closed, the workpiece to be stamped on the stamping station will be stamped. At this time, the push plate 503 is located on the support plate 501 and outside the lower mold part 1. At this time, the workpiece to be stamped can be placed in the loading trough 504, and then in the process of the upper mold part 2 of the mold opening moving upward, the demoulding assembly 3 will push the stamping part in the concave mold cavity 105 upward, and in the process of the upper mold part 2 moving upward, it will also drive the second rack 407 to move upward synchronously. In the front part of the upward movement, since the second rack 407 is not engaged with the first gear 403, it will not drive the first gear 403 to rotate. When the upper mold part 2 moves up to a certain height, the second rack 407 is engaged with the first gear 403, and then The upper mold part 2 drives the second rack 407 to continue to move upward. At this time, the second rack 407 can drive the transmission shaft 402 and the second gear 404 to rotate through the first gear 403, and the second gear 404 drives the first rack 405 to slide in the direction of the die cavity 105. Moreover, since the diameter of the first gear 403 is smaller than the diameter of the second gear 404, the sliding speed of the first rack 405 will increase relative to the upward speed of the second rack 407. The sliding second rack 407 drives the push plate 503 to slide in the direction of the die cavity 105 through the connecting rod 502. The sliding push plate 503 can push the stamping part ejected by the demoulding component 3 out of the mold, thereby achieving the purpose of automatically pushing the stamping part out of the mold.

[0063] At the same time as the stamping part is pushed out, the push plate 503 will also push the workpiece to be stamped previously placed inside it to the stamping station at the die cavity 105 through the loading trough 504, until the workpiece to be stamped is pushed to the top of the positioning groove 106. At this time, under the action of gravity, the workpiece to be stamped is separated from the loading trough 504 and falls into the positioning groove 106. The press starts to control the upper die part 2 to move down and close the mold. In this process, the second rack 407 drives the first gear 403 and the second gear 407 to move down to close the mold. The wheel 404 rotates in the opposite direction, and thereby pushes the first rack 405 and the push plate 503 back to their original positions on the support plate 501 to avoid affecting the stamping work. Then the upper die part 2 moves downward to stamp the workpiece to be stamped in the positioning groove 106, and at the same time, another workpiece to be stamped can be placed in the loading groove 504 to prepare for the next round of stamping. Then the upper die part 2 moves up again to open the mold and repeat the above actions, finally achieving the purpose of automatically placing the workpiece to be stamped into the stamping station.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
