Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a material ejection device for automotive stamping die processing. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts.

[0003] In the prior art, when stamping parts are processed by stamping dies, the rigid stamping will lock the stamping parts in the stamping cavity of the stamping die. The stamping parts are locked in the stamping cavity and it is not easy to unload them. Manual operation is required to force unload them. However, manually prying them up with a crowbar will squeeze and deform the stamping parts, thus affecting the stamping quality. Therefore, we propose an unloading device for automotive stamping die processing. Utility Model Content

[0004] This utility model is proposed to address the shortcomings of existing technologies by providing a material ejection device for automotive stamping die processing. This material ejection device solves the problem that when rigid stamping of stamping dies results in material jamming, manual removal of the material is required, which affects the stamping processing efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An ejector device for processing automotive stamping dies includes a support platform. Two side plates are symmetrically arranged on the upper side of the support platform. A translation clamping assembly is provided on one side of each side plate. A horizontal plate is provided on the upper side of the side plate. A hydraulic cylinder is provided on the upper side of the horizontal plate. An upper die is provided at the end of the hydraulic cylinder. A lower die is provided on the upper side of the support platform and opposite to the upper die. A stamping cavity is provided inside the lower die, and a stamping part ejection assembly is provided inside the stamping cavity.

[0007] The above technical solution involves placing the workpiece to be stamped on the lower mold, then using a hydraulic cylinder to control the upper mold to fit with the lower mold and stamp the workpiece. After stamping, the workpiece will be rebounded by the ejector assembly, causing it to detach from the lower mold. At the same time, the translation clamping assembly clamps and moves the ejected workpiece to remove it, thus providing an automatic stamping and ejection movement function.

[0008] Preferably, the upper side of the lower mold is provided with several grooves, a spring is provided in the groove, a limit block is provided at the top of the spring, the limit block is slidably connected in the groove, and one side of the limit block is provided with an arc edge structure.

[0009] Through the above technical solution, the limiting block and spring provide a simple positioning function for a pair of stamped parts. The limiting block moves in the groove and compresses the spring to retract, thereby achieving a retractable limiting function.

[0010] Preferably, the translation clamping assembly includes a guide groove, which is disposed on one side of the side plate. A motor is disposed on one side of the side plate, and a transmission rod is disposed on the shaft end of the motor. The transmission rod is placed in the guide groove, and a guide block is threaded to the outer side of the transmission rod. An electric push rod is disposed on one side of the guide block, and a rubber plate is disposed at the output end of the electric push rod.

[0011] With the above technical solution, after the stamping of the stamped part is completed, two electric push rods simultaneously push the rubber plates, and the two rubber plates clamp the stamped part. Then, the motor drives the transmission rod to rotate, and the transmission rod rotates the threaded transmission guide block. The guide block drives the electric push rod to move, so that the stamped part clamped by the rubber plates is displaced and ejected, thereby providing an automatic clamping and ejection function.

[0012] Preferably, guide platforms are provided on both sides of the support platform, with one side of the guide platform abutting against one side of the lower mold.

[0013] The above technical solution uses a guide platform to guide the stamped parts after stamping.

[0014] Preferably, the stamping part ejection assembly includes a receiving groove, which is located at the bottom inner side of the stamping cavity. Several guide rods are arranged through the receiving groove. A limiting piece is provided at the bottom end of the guide rod. A second spring is provided on the upper side of the limiting piece. The top end of the second spring is connected to the lower side of the support platform. A push plate is provided at the top end of the guide rod.

[0015] With the above technical solution, when the upper mold and the lower mold are closed, the lower mold pushes the push plate to move in the stamping cavity and enter the receiving groove. At the same time, the push plate drives the limit plate to move down and pull the second spring. When the upper mold and the lower mold are separated, the rebound force of the second spring will reset the push plate, that is, push the stamped part out of the stamping cavity, thus providing an automatic demolding function.

[0016] In summary, this utility model places the workpiece to be stamped on the lower mold, and then uses a hydraulic cylinder to control the upper mold to fit with the lower mold to stamp the workpiece. After stamping, the workpiece will be rebounded by the stamping part ejection component, causing the stamping part to detach from the lower mold. At the same time, the translation clamping component clamps and translates the ejected stamping part to remove the material, thus providing an automatic stamping and unloading movement function.

[0017] In this invention, when the upper and lower molds are closed, the lower mold pushes the push plate in the stamping cavity and enters the receiving groove. At the same time, the push plate drives the limiting piece to move down and pull the second spring. When the upper and lower molds are separated, the rebound force of the second spring will reset the push plate, that is, push the stamped part out of the stamping cavity, thus providing an automatic demolding function.

The guide groove 10 is located on one side of the side plate 2. A motor 11 is located on one side of the side plate 2. A transmission rod 12 is provided at the shaft end of the motor 11 and is placed within the guide groove 10. A guide block 13 is threaded to the outer side of the transmission rod 12. An electric push rod 14 is provided on one side of the guide block 13. A rubber plate 15 is provided at the output end of the electric push rod 14. A horizontal plate 3 is provided on the upper side of the side plate 2. A hydraulic cylinder 4 is provided on the upper side of the horizontal plate 3. An upper die 5 is provided at the end of the hydraulic cylinder 4. A lower die 6 is provided on the upper side of the support platform 1, opposite to the upper die 5.

[0024] The lower mold 6 is provided with a stamping cavity 7, and a stamping part ejection assembly is provided in the stamping cavity 7. The stamping part ejection assembly includes a receiving groove 17, which is located at the bottom of the inner side of the stamping cavity 7. Several guide rods 18 are provided through the receiving groove 17. A limiting piece 19 is provided at the bottom end of the guide rod 18.

[0025] In this embodiment, the workpiece to be stamped is placed on the lower mold 6, and then the upper mold 5 and the lower mold 6 are controlled by the hydraulic cylinder 4 to press the workpiece. When the upper mold 5 and the lower mold 6 are closed, the lower mold 6 pushes the push plate 21 to move in the stamping cavity 7 and enters the receiving groove 17. At the same time, the push plate 21 drives the limiting piece 19 to move down and pull the second spring 20. After the stamping is completed, after the upper mold 5 and the lower mold 6 are separated, the rebound force of the second spring 20 will reset the push plate 21, that is, push the stamped part out of the stamping cavity 7 and make the stamped part separate from the lower mold 6. At the same time, after the stamping is completed, the two electric push rods 14 push the rubber plate 15 at the same time. The two rubber plates 15 clamp the stamped part. Then the motor 11 drives the transmission rod 12 to rotate. The transmission rod 12 rotates the threaded transmission guide block 13. The guide block 13 drives the electric push rod 14 to move, so that the stamped part clamped by the rubber plate 15 is displaced and ejected, and falls onto the guide table 16 for conveying.
