Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0050] Please see Figure 1-4 This utility model provides a technical solution: a stamping die that facilitates the replacement of the stamping die head, comprising:

[0051] Mold base 1, with a rectangular slot 2 at the front end;

[0052] A window 7 is provided in the center of the bottom surface of the rectangular slot 2;

[0053] A rectangular plate 3 is inserted into the rectangular slot 2, and a movable mold 4 is integrally formed at its lower end.

[0054] After the rectangular plate 3 is fully inserted into the rectangular slot 2, there is space between its front end and the front end of the rectangular slot 2.

[0055] The moving mold 4 extends outward through window 7;

[0056] After the rectangular plate 3 is fully inserted into the rectangular slot 2, a rectangular groove 21 is provided on the top surface of the space between the front end of the rectangular plate 3 and the front end of the rectangular slot 2.

[0057] A first strip-shaped through hole 22 is horizontally opened in the middle of the top surface of the rectangular groove 21;

[0058] A baffle 23 passes through the first strip-shaped through hole 22 and is inserted into the rectangular groove 21 and the rectangular slot 2;

[0059] A finger insertion hole 6 is provided on the front wall of the rectangular groove 21;

[0060] When a finger is inserted into the insertion hole 6, the operator holds and pushes the baffle 23 to move backward and fit against the front wall of the rectangular plate 3, and at this time the top of the baffle 23 fits against the rear side of the top surface of the rectangular groove 21.

[0061] The front end of the rectangular groove 21 is equipped with a screw-type limiting and blocking structure 5, and the movable part located in the rectangular groove 21 partially blocks and abuts against the front wall of the baffle 23.

[0062] Specifically in this embodiment, the mold base 1 is used to be fixedly connected to other equipment and drive it to move up and down. A rectangular plate 3 is fixed on the upper end of the moving mold 4. A rectangular slot 2 is opened on the front wall of the mold base 1. During installation, the rectangular plate 3 is slid into the rectangular slot 2. The lower end of the moving mold 4 extends to the outside through the window 7 opened on the bottom surface of the rectangular slot 2.

[0063] Furthermore, a rectangular groove 21 is opened at the upper front end of the rectangular slot 2, and a first strip-shaped through hole 22 is opened horizontally in the middle of its top surface. A baffle 23 is inserted through the first strip-shaped through hole 22. A finger is inserted through the finger insertion hole 6 connected to the rectangular groove 21 and pushes the baffle 23 to move backward and abut against the front wall of the rectangular plate 3. At this time, the top of the baffle 23 fits against the rear wall of the top surface of the rectangular groove 21 for vertical positioning. Finally, the movable part of the screw-type limiting and blocking structure 5 moves inward to block and position the baffle 23 on the front wall of the baffle 23, thereby limiting and fixing the installation position of the rectangular plate 3 and realizing the installation and fixing of the moving mold 4.

[0064] More specifically, when it is necessary to disassemble the moving mold 4, the movable part of the screw-type limiting and blocking structure 5 is adjusted to move outward and no longer block the front wall of the baffle 23. The baffle 23 is pushed forward from the window 7 so that the upper end of the baffle 23 corresponds to the first strip-shaped through hole 22. Then, the baffle 23 is pushed upward from the window 7 and passed through the first strip-shaped through hole 22 to be pulled out. Then, the rectangular plate 3 is slid off from the front end of the rectangular slot 2.

[0065] It is understandable that the front end of the rectangular slot 2 can be inserted into the baffle 23, which has the same function as the finger insertion hole 6. The pushing position of the finger insertion hole 6 corresponds to the middle position of the baffle 23. After pushing the baffle 23 through the front end of the rectangular slot 2 and moving it to fit the rectangular plate 3, pushing the middle of the baffle 23 through the finger insertion hole 6 ensures that the baffle 23 fits tightly with the rectangular plate 3.

[0066] In some embodiments, the screw-type limiting and shielding structure 5 includes:

[0067] A threaded through hole 51 is formed on the left and right sidewalls of a rectangular groove 21;

[0068] A screw 52 is screwed into the threaded through hole 51, and its inner end abuts against the front wall of the baffle 23.

[0069] Specifically in this embodiment, the screw 52 is screwed into the threaded through hole 51, and the rotating screw 52 moves inward to abut against the front wall of the baffle 23 to block and position it.

[0070] Furthermore, the screw 52 can be rotated outward to release its obstruction and positioning of the front wall of the baffle 23.

[0071] In some embodiments, a cylinder is fixedly mounted on the outer end of the screw 52, ​​and the outer wall of the cylinder is provided with anti-slip texture 53.

[0072] Specifically in this embodiment, a cylinder is used instead of a screw 52 for gripping, which facilitates the rotation operation of the screw 52;

[0073] Furthermore, anti-slip texture 53 is formed on the outer wall of the cylinder to increase the friction of the outer wall of the cylinder and facilitate its rotation operation.

[0074] In some embodiments, the front end of the inner wall of the finger insertion hole 6 is rounded.

[0075] The inner wall of the finger insertion hole 6 is polished to prevent damage to the finger skin when the finger is inserted.

[0076] In some embodiments, a slot 24 is laterally provided on the rear wall of the rectangular groove 21;

[0077] The rear wall of the baffle 23 has a strip-shaped insert 25 integrally formed with the slot 24 corresponding to the slot 24.

[0078] The strip-shaped insert 25 is inserted into the slot 24.

[0079] Specifically in this embodiment, the strip-shaped insert 25 is inserted into the slot 24 to enhance the stability of the baffle 23 after it is inserted into the rear wall of the rectangular groove 21, and to reduce the possibility of the baffle 23 shifting forward or backward before or during the inward movement of the movable part of the screw-type limiting shielding structure 5.

[0080] In some embodiments, there are two slots 24, and the two slots 24 are evenly and longitudinally opened on the rear wall of the rectangular groove 21;

[0081] The rear wall of the baffle 23 has a strip-shaped insert 25 integrally formed with the slot 24 corresponding to the slot 24.

[0082] The strip-shaped insert 25 is inserted into the corresponding slot 24; increasing the number of slots 24 and corresponding strip-shaped inserts 25 further enhances the stability of the baffle 23 after it is inserted into the rear wall of the rectangular groove 21, and avoids the baffle 23 from moving forward or backward before or during the inward movement of the movable part of the screw-type limiting shielding structure 5.

[0083] In some embodiments, a round rod 8 is inserted into the finger insertion hole 6, the length of which is greater than the length of the finger insertion hole 6, and the round rod 8 is used to replace the finger in the finger insertion hole 6.

[0084] In some embodiments, connecting ear plates 9 are fixedly mounted on the upper edges of the front and rear side walls of the mold base 1. The connecting ear plates 9 are connected and fixed to the mounting platform by bolts passing through the pre-drilled holes on them. Example

[0085] Please see Figure 5 and Figure 6The difference between this embodiment and the first embodiment is that the length of the first strip-shaped through hole 22 is replaced by a second strip-shaped through hole 22a with a smaller length value;

[0086] The size of the baffle 23 into which the second through hole 22a is inserted is matched;

[0087] A rectangular block 54 is rotatably connected to the inner end of the movable part of the screw-type limiting and blocking structure 5.

[0088] The outer wall of rectangular block 54 slides and fits against the front wall of baffle 23.

[0089] Specifically, in this embodiment, a baffle 23 of matching size is inserted into the second through hole 22a;

[0090] Furthermore, the movable part of the screw-type limiting and blocking structure 5 moves inward, causing the rectangular block 54 that rotates with it to slide along the front wall of the baffle 23, increasing the contact area with the front wall of the baffle 23 and improving the stability of the limiting and blocking.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
