[0022] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] See also Figure 1-3 The utility model provides a technical solution: a stamping die that is easy to eject, including a workbench 1 and an ejection assembly. A top plate 2 is arranged on the top of the workbench 1, and the ejection assembly is arranged on the workbench 1. The ejection assembly includes a movable plate 8, a push rod 9, a slider 12 and a reset spring 13. The top of the movable plate 8 is fixedly installed with a push rod 9, and two groups of sliders 12 are slidably arranged on both sides of the movable plate 8 and are symmetrically distributed. The bottom of the slider 12 is fixedly installed with a reset spring 13.

[0024] Furthermore, multiple groups of columns 3 are fixedly installed between the workbench 1 and are distributed in a rectangular array. A movable plate 4 is slidably installed on the outer wall of the column 3, and a hydraulic rod 5 is fixedly installed on the top of the top plate 2. The free end of the hydraulic rod 5 passes through the top plate 2 and is fixedly installed on the top of the movable plate 4, which can drive the movable plate 4 to slide up and down on the column 3.

[0025] Furthermore, an upper mold 6 is fixedly installed on the bottom of the movable plate 4 , and a lower mold 7 is fixedly installed on the top of the workbench 1 .

[0026] Furthermore, the ejection assembly also includes a transverse plate 10 and an L-shaped connecting plate 11. The top of the movable plate 8 extends to the inside of the lower mold 7. The bottom end of the reset spring 13 is fixedly installed with the transverse plate 10. Two groups of L-shaped connecting plates 11 are fixedly installed on the top of the transverse plate 10 and are symmetrically distributed. The top of the L-shaped connecting plate 11 fits with the bottom of the workbench 1. The L-shaped connecting plate 11 and the workbench 1 are fixedly installed by bolts. A damper is arranged inside the reset spring 13. When the stamping is completed and the upper mold 6 is away from the workpiece, the ejector rod 9 drives the workpiece to lift upward through the reaction force of the reset spring 13, so that the workpiece can be taken out. After the stamping is completed, the workpiece can be quickly and automatically ejected from the lower mold 7, thereby saving the time of ejecting the workpiece in each operation and reducing production. The production cycle is shortened, and production efficiency is improved. At the same time, it can ensure that each workpiece is ejected from the mold in the same way, which improves the consistency and quality control of the production process. This is particularly important for large-scale production. It can reduce product differences caused by human factors, reduce the physical labor of operators, and improve work comfort and safety. When the ejector assembly needs to be replaced, the bolts on the L-shaped connecting plate 11 are removed, and then the slider 12 can be removed from the movable plate 8 by pulling the cross plate 10. The operator can easily disassemble and inspect the automatic ejector assembly, perform necessary cleaning, lubrication or replace worn parts, allowing the operator to make adjustments and changes according to specific production needs, thereby extending the service life of the mold and reducing downtime.

[0027] Secondly, the upper die 6 and the lower die 7 are on the same center line, which improves the stamping quality of the workpiece.

[0028] Working principle: When in use, place the workpiece on the lower mold 7, start the hydraulic rod 5, and push the upper mold 6 on the movable plate 4 downward by controlling the extension and retraction of the hydraulic rod 5, so that the workpiece on the lower mold 7 is stamped. During the stamping process, the workpiece will squeeze the push rod 9, so that the movable plate 8 on the push rod 9 compresses the reset spring 13. When the stamping is completed, when the upper mold 6 is away from the workpiece, the push rod 9 drives the workpiece to lift upward through the reaction force of the reset spring 13, and the workpiece can be taken out. When the ejection assembly needs to be replaced, the bolts on the L-shaped connecting plate 11 are removed, and then the cross plate 10 is pulled to remove the slider 12 from the movable plate 8, and it can be replaced.

[0029] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
