[0002] Die-cutting common hardware mold frame is a support structure used for hardware die-cutting dies. It is mainly made of high-strength materials such as steel and aluminum alloy, and has the characteristics of stable structure, high precision and good wear resistance. Among them, hardware mold frame is a die support structure used to manufacture various metal products.

[0003] For example, the die-cutting common hardware mold frame structure disclosed in Chinese patent application number CN201820997118.X specifically includes a lower mold plate and an upper mold plate. The upper mold plate has three rows of central blind holes in the middle of its bottom. Upper guide holes are opened on both sides of the central blind holes, and side blind holes are opened outside the upper guide holes. Magnets are embedded in both the central blind holes and the side blind holes, with the end faces of the magnets flush with the surface of the upper mold plate. However, it still has the following technical problems:

[0004] Magnets are embedded in blind holes to attract the die-cutting mold. However, when the die-cutting mold is disassembled, the magnets may shift, causing them to be higher than the surface of the upper template. This can affect the placement of the die-cutting mold during installation. Utility Model Content

[0005] To address the problem mentioned in the background art that the magnet is easily displaced during the disassembly of the die-cutting mold, this utility model provides the following technical solution:

[0006] A die-cutting common hardware mold frame, including an upper mold and a lower mold;

[0007] The upper mold has multiple first magnetic blocks installed in the middle for adsorbing the die.

[0008] The upper mold has multiple limiting holes in the middle for limiting the first magnetic block. A first connecting hole is provided on one side of the limiting hole, and a limiting groove is connected to one side of the cavity of the first connecting hole.

[0009] The limiting groove is equipped with a limiting cover plate for positioning the first magnetic block, and a locking element for locking the limiting cover plate is installed in the limiting groove.

[0010] Furthermore, the lower die has multiple first punch holes in the middle, and a base plate is installed on one side of the lower die.

[0011] Furthermore, the upper mold has a plurality of second punch holes in the middle for aligning with the first punch holes, and side blocks are installed on both sides of the upper mold, with guide holes on both sides of the side blocks.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] The terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model.

[0030] Please see Figures 1-7This utility model provides a common hardware die set for die cutting, including an upper die 100 and a lower die 200. The lower die 200 has a plurality of first punch holes 210 in its middle. This utility model includes three types of lower dies 200: the first type has the first punch holes 210 located on the innermost side; the second type has the first punch holes 210 located in the middle of the lower die 200; and the third type has the first punch holes 210 located on the outer side of the lower die 200. A base plate 220 is mounted on one side of the lower die 200.

[0031] The upper mold 100 has multiple second punch holes 130 in the middle for alignment with the first punch hole 210. Each row of second punch holes 130 is equidistant in the middle of the upper mold 100, and each second punch hole 130 is a small hole with a diameter of 3mm. By setting multiple second punch holes 130, punches can be placed according to product size requirements.

[0032] Side blocks 110 are fixedly installed on both sides of the upper mold 100. Guide holes 111 are opened on both sides of the side blocks 110. The guide rod on the lower mold 200 passes through the guide holes 111 to facilitate the positioning of the upper mold 100, so that the upper mold 100 is more stable when it moves up and down.

[0033] Multiple first magnetic blocks 140 for adsorbing the die-cutting mold are installed in the middle of the upper mold 100. The surface of the first magnetic blocks 140 is flush with the surface of the upper mold 100 to prevent the first magnetic blocks 140 from protruding and affecting the placement of the die-cutting mold. Multiple limiting holes 120 for limiting the first magnetic blocks 140 are opened in the middle of the upper mold 100. A first connecting hole 121 is opened on one side of the limiting hole 120, and the cavity diameter of the first connecting hole 121 is larger than the cavity diameter of the limiting hole 120. The cross-section of the first magnetic block 140 is T-shaped, so that the small cylindrical end of the first magnetic block 140 is placed in the limiting hole 120 and the large cylindrical end of the first magnetic block 140 is placed in the first connecting hole 121. The first connecting hole 121 limits the large cylindrical end of the first magnetic block 140, so that the die-cutting mold is not likely to cause the first magnetic block 140 to shift when it is disassembled. A limiting groove 150 is connected to one side of the cavity of the first connecting hole 121, and the limiting groove 150 is connected to the side wall of the upper mold 100.

[0034] A limiting cover plate 160 for positioning the first magnetic block 140 is installed in the cavity of the limiting groove 150. A locking member 170 for locking the limiting cover plate 160 is installed in the cavity of the limiting groove 150. The limiting cover plate 160 is a rectangular plate and is detachable. A plurality of abutments 161 for abutting against the first magnetic block 140 are fixedly installed on one side of the limiting cover plate 160. A circular hole 162 is opened in the middle of the limiting cover plate 160, and circular holes 162 are opened at both ends of the limiting cover plate 160. Second connecting holes 163 are machined on both sides of the circular holes 162. The second connecting holes 163 are provided to facilitate the locking member 170 to move from below the limiting cover plate 160 near the abutments 161 to above the limiting cover plate 160. Two second magnetic blocks 164 are fixedly installed in the middle of the limiting cover plate 160, and the second magnetic blocks 164 are located on both sides of the circular hole 162, so that when the locking member 170 passes through the circular hole 162 and the second connecting hole 163, the second magnetic blocks 164 lock the locking member 170.

[0035] The locking component 170 includes a fixing block 171, which is fixedly installed in the cavity of the limiting groove 150. A rotating block 172 is movably installed at one end of the fixing block 171, and the rotating block 172 can rotate within the fixing block 171. An adjusting knob 173 is fixedly installed at one end of the rotating block 172, and a third magnetic block 174 for magnetic attraction with the second magnetic block 164 is fixedly installed at both ends of the adjusting knob 173.

[0036] After the first magnetic block 140 is installed in the limiting hole 120 and the first connecting hole 121, the limiting cover plate 160 is placed into the cavity of the limiting groove 150, so that the abutment 161 and the first magnetic block 140 abut against each other, so that one side of the small cylindrical end of the first magnetic block 140 is flush with the surface of the upper mold 100. After the limiting cover plate 160 is inserted into the cavity of the limiting groove 150, the adjusting knob 173 passes through the cavity of the round hole 162 and the second connecting hole 163, and the fixing block 171 is in the cavity of the round hole 162. By rotating the adjusting knob 173 ninety degrees, the third magnetic block 174 moves closer to the second magnetic block 164 and is magnetically attracted to the second magnetic block 164, thereby locking the limiting cover plate 160, so that the first magnetic block 140 is relatively stable in the limiting hole 120, which facilitates the disassembly of the die.

[0037] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
