[0027] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application.

[0028] As Figures 1 to 4 shown, a stamping and forming ejection mechanism includes a stamping base 1 for installing a mold and a placement groove 5 provided on one side of the stamping base 1. A mold is provided on the stamping base 1. A plurality of perforations 3 are provided at the top of the inner wall of the placement groove 5. A hidden groove 2 is provided between the perforations 3 and the top of the stamping base 1. A pushing block 4 is slidably provided in the hidden groove 2. The stamping and forming ejection mechanism further includes:

[0029] A driving part 7 for driving the pushing block 4 to move vertically up and down.

[0030] A limiting part 6 provided in the placement groove 5 for limiting and fixing the driving part 7.

[0031] The limiting part 6 includes:

[0032] A limiting seat 61 fixed to the top of the inner wall of the placement groove 5. A cross groove 62 is horizontally provided on one side of the limiting seat 61. A fitting groove 63 for communicating with the cross groove 62 is provided at the bottom of the limiting seat 61.

[0033] The driving part 7 includes:

[0034] An insertion plate 73 horizontally inserted into the cross groove 62.

[0035] A connecting block 72 horizontally sleeved in the fitting groove 63. The connecting block 72 is fixed to the bottom of the insertion plate 73.

[0036] During the alternating replacement interval between the old die and the new die on the stamping base 1, such operation can avoid the die from interfering with the normal installation or disassembly operations of the driving part 7 and the pushing block 4. The disassembly or installation steps of the driving part 7 and the pushing block 4 are as follows: First, disassemble and separate the pushing block 4 from the driving part 7. Then, horizontally pull out the connecting block 72 together with the inserting plate 73 from the limit seat 61. Next, horizontally push it into the limit seat 61 corresponding to the new die, so that the connecting block 72 and the inserting plate 73 are respectively inserted into the fitting groove 63 and the cross groove 62, and the preliminary replacement operation of the driving part 7 can be completed. Then, install the pushing block 4 and the new die in place in sequence, optimize the replacement steps of the driving part 7, reduce the difficulty of the replacement operation of the driving part 7, and reduce the impact of the replacement operation of the driving part 7 on the processing efficiency of the stamping parts.

[0037] In this embodiment, the inserting plate 73 is located at the middle of the inside of the cross groove 62, and the length and width of the inserting plate 73 are larger than those of the connecting block 72. By inserting the inserting plate 73 at the vertical middle of the cross groove 62, a certain space can be reserved between the top of the inserting plate 73 and the top of the inner wall of the placement groove 5, ensuring that the driving part 7 can be smoothly installed in place and can be aligned with the through hole 3 vertically, facilitating the subsequent installation operation of the pushing block 4.

[0038] In this embodiment, the fitting groove 63 matches the connecting block 72, and one side of the fitting groove 63 is open. Such a design is to initially restrict the degrees of freedom of the connecting block 72 and the inserting plate 73 in most directions through the fitting groove 63, avoiding the driving part 7 from having a lateral position offset during operation, which may interfere with its normal operation. The open design is to horizontally push the connecting block 72 and the inserting plate 73 into the fitting groove 63 and the cross groove 62, and enable them to be installed in place.

[0039] In this embodiment, the driving part 7 further includes a telescopic rod 71 fixed to the bottom of the connecting block 72 for pushing the pushing block 4 to move linearly up and down. The free end of the telescopic rod 71 is inserted into the through hole 74 provided on the connecting block 72 and the inserting plate 73. Such a design can complete the disassembly and assembly of the telescopic rod 71 through the insertion and extraction method of the connecting block 72 and the inserting plate 73, without disassembling the telescopic rod 71 itself, realizing the modular disassembly or installation of the telescopic rod 71, thereby achieving the effect of optimizing the disassembly and assembly steps of the telescopic rod 71. Before disassembling the telescopic rod 71, it is necessary to first disassemble and separate the pushing block 4 from the telescopic rod 71, and then retract the free end of the telescopic rod 71 to the lowest position, so as to ensure that the telescopic rod 71 can be smoothly disassembled or installed in place.

[0040] In this embodiment, the perforation 3 corresponds to the limiting seat 61, and the perforation 3 matches the free end of the telescopic rod 71. When the connecting block 72 is properly installed in the fitting groove 63, the perforation 3 can be aligned with the free end of the telescopic rod 71, so as to facilitate the elongation of the free end of the telescopic rod 71 and its insertion into the perforation 3. This can not only improve the disassembly and assembly efficiency of the driving part 7, but also respectively restrict the degrees of freedom of the insertion plate 73 vertically through the cross groove 62 and the perforation 3, and restrict the degree of freedom of the telescopic rod 71 horizontally, realizing mutual restraint between the two. As long as the free end of the telescopic rod 71 is kept inside the perforation 3, the stability and firmness of the operation of the driving part 7 can be improved.

[0041] In this embodiment, the free end of the telescopic rod 71 passes through the perforation 3 and extends into the dark groove 2, and the free end of the telescopic rod 71 is threadedly arranged at the bottom of the pushing block 4. With such a design, when the telescopic rod 71 is disassembled, first disassemble and separate the pushing block 4 from the free end of the telescopic rod 71, and then contract the free end of the telescopic rod 71 to the lowest position, so that the free end of the telescopic rod 71 can be disengaged from the perforation 3, releasing the limiting and fixing effect of the perforation 3 and the cross groove 62 on the telescopic rod 71, facilitating the user to disassemble the telescopic rod 71 by horizontally moving it, so as to change the installation position of the telescopic rod 71 and facilitate its continuous ejection of the workpiece processed by the new mold.

[0042] The above are only the preferred embodiments of the present invention, and the parts not described in the present invention can be realized by adopting or referring to the existing technologies. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present invention should also fall within the protection scope of the present invention.
