Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 and FIG. 2 , the stamping die of the present invention includes an upper die, a lower die and a return mechanism 50 .

The upper mold has an upper template (not shown in the figure), and a forming punch 10 and a pushing punch 20 are installed on the upper template. The forming punch 10 has a columnar first base 11, and the lower end of the first base 11 is It has a stamping part 111; the pushing punch 20 has a columnar second base 21, and the lower end of the second base 21 has a pushing part 211; Used for punching guide and fixing strip 80.

The lower mold and the upper mold are arranged correspondingly, including a lower mold base (not shown) and a forming slider 40, and the forming slider 40 is slidably held on the lower mold base, and has a forming portion 41 and a beveled surface 42, the forming part 41 corresponds to the stamping part 111 of the forming punch 10, and the beveled surface 42 corresponds to the pushing part 211 of the pushing punch 20; Hole 43.

The return mechanism 50 is installed between the lower mold base and the forming slider 40, and includes a fixing plate 51, a fixing screw pin 52 and a spring 53; the fixing plate 51 is fixed on the lower mold base and is close to the forming slider The position on the left side of 40 has a square substrate 511, and the center of the substrate 511 offers a through hole 512 through the substrate 511; the fixed screw pin 52 has a cylindrical pin body 521 and a circular pin cap 522; 52 sets of fixed screw pins The upper spring 53 passes through the through hole 512 of the fixing plate 51 and is fixed in the fixing hole 43 on the left side of the forming slider 40 , and the spring 53 is compressed between the pin cap 522 and the fixing plate 51 .

Please refer to Fig. 3 and Fig. 4, when the product is stamped, the upper die moves downward, driving the pushing part 211 of the push punch 20 to squeeze the beveled surface 42 of the forming slider 40, so that the forming slider 40 slides to the material belt The lower surface of 80; the stripping part 30 is then pressed down on the upper surface of the strip 80, thus the strip 80 is fixed in the mold;

Please refer to Fig. 5 and Fig. 6, the upper die moves upward, driving the pushing punch 20 and the stripping part 30 to move upward together; the forming slider 40 slides down under the action of the spring 53 to discharge the material belt 80 so that the material belt 80 is not hindered Exit the stamping area smoothly, so as to start the next round of stamping production.

The stamping mold of the utility model extends into and exits the stamping area through the forming slider 40, and can successfully complete the stamping and forming of the product without hindering the material strip 80 from entering and exiting the mold, ensuring the continuity and accuracy of production, and further improving production efficiency.
