One of the upper die frame 110 and the upper die frame 120 is provided with a plurality of upper positioning blocks 111, the other is provided with a plurality of upper positioning grooves, and when the plurality of upper positioning blocks 111 extend into the plurality of upper positioning grooves in a one-to-one correspondence manner, the upper die frame 120 and the upper die frame 110 can be detachably connected through threaded fasteners.

In the above general type stamping die, the upper die assembly 100 includes the upper die frame 110 and the upper die 120, the lower die assembly 200 includes the lower die frame 210 and the lower die 220, and the upper die 120 and the lower die 220 are used for molding materials during die assembly, that is, the upper die 120 and the lower die 220 are manufactured differently based on the shape of the desired stamping.

It can be appreciated that the detachable connection mode realized by the threaded fastener has the advantages of simple structure, low manufacturing difficulty and convenient operation in the disassembly and assembly process.

With continued reference to fig. 3-4, in some embodiments, a plurality of upper lugs 121 are preferably disposed around the side walls of the upper die 120; a plurality of lower lugs 221 are disposed around the sidewall of the lower mold 220 in a circle.

Specifically, the upper mold 120 has an overall shape similar to a rectangular parallelepiped, four sidewalls of which are provided with upper lugs 121 protruding outward, and a plurality of upper lugs 121 are arranged at intervals therebetween, thereby stably fixing each region of the upper mold 120 to the upper mold frame 110. Similarly, the lower mold 220 has an overall shape similar to a rectangular parallelepiped, and four sidewalls thereof are provided with lower lugs 221 protruding outward, and a plurality of lower lugs 221 are arranged at intervals therebetween, thereby stably fixing each region of the lower mold 220 to the lower mold frame 210.

Referring to fig. 5 to 6, in the embodiment shown in the drawings, an upper positioning block 111 is disposed on an upper mold frame 110, an upper positioning groove is disposed on an upper mold 120, and the upper mold 120 and the upper mold frame 110 are positioned by the plug-in matching of the two, so that the two can achieve position alignment, and then are fixed together by a threaded fastener.

When the upper positioning block 111 and the upper positioning groove are provided in the above-described shape, positioning in two directions (for example, the length direction and the width direction of the upper die 120) can be simultaneously achieved, and positioning is more rapid and convenient. Similarly, when the lower positioning block 211 and the lower positioning groove are provided in the above-described shapes, positioning in both directions (for example, the length direction and the width direction of the lower die 220) can be simultaneously achieved, and positioning is more rapid and convenient.

Referring to fig. 2, 3 and 5, in some embodiments, the upper die assembly 100 includes a fixing plate 130, a driving member and a pressing core mechanism, the pressing core mechanism is embedded in the upper die 120 and slidably connected with the fixing plate 130, the fixing plate 130 is fixed on a side of the upper die frame 110 facing away from the upper die 120, the driving member is fixedly mounted on the fixing plate 130, and a telescopic end of the driving member passes through the upper die frame 110 and is fixedly connected with the pressing core mechanism, and the driving member can drive the pressing core mechanism to extend out of a molding surface of the upper die 120 so as to form a pit on a material.

Specifically, the upper die frame 110 is provided with a hole site penetrating along a first direction, through which the driving member passes, so that the telescopic end of the driving member can be fixedly connected with the pressing core mechanism, and the pressing core mechanism is driven to extend out of the molding surface of the upper die 120 along the first direction, so that a pit is formed on the material. In the embodiment of the present application, in the use state, the upper die assembly 100 is located above the lower die assembly 200, the molding surface of the upper die 120 is the bottom surface thereof, and the molding surface of the lower die 220 is the top surface thereof. In this embodiment, by providing the above-mentioned material pressing structure, the material pressing structure can be matched with the shapes of the upper die 120 and the lower die 220, so as to form a shape with higher complexity.

With continued reference to fig. 2, 3 and 5, in some embodiments, the press core mechanism includes a first press core 141 and a second press core 142, the driving member includes a first driving portion 151 and a second driving portion 152, the second press core 142 is embedded in the first press core 141 and slidably connected to the first press core 141, the first press core 141 is embedded in the upper die 120 and slidably connected to the second press core 152, the first driving portion 151 and the second driving portion 152 are fixedly mounted on the fixing plate 130, a telescopic end of the first driving portion 151 passes through the upper die frame 110 and is fixedly connected to the first press core 141, a telescopic end of the second driving portion 152 passes through the upper die frame 110 and is fixedly connected to the second press core 142, the first driving portion 151 can drive the first press core 141 to extend beyond a molding surface of the upper die 120, and the second driving portion 152 can drive the second press core 142 to extend beyond a molding surface of the first press core 141.

Specifically, the upper die 120 is provided with a first through groove 122 penetrating along a first direction, and the first pressing core 141 is embedded in the first through groove 122, and the shape and the size of the first pressing core and the first through groove are matched. The first pressing core 141 is fixedly connected with a sliding rod 171, the upper die frame 110 is provided with a sliding groove 112 matched with the sliding rod 171 in shape and size, and the sliding rod 171 passes through the first through groove 122 and then extends into the sliding groove 112. When the first driving part 151 drives the first pressing core 141 to extend out of the molding surface of the upper die 120, the slide rod 171 slides in the slide groove 112 to realize guiding. Preferably, a plurality of sliding rods 171 and sliding grooves 112 are provided to enhance guiding and improve stability of the movement process.

The first press core 141 is provided with a second through groove 1411 penetrating in the first direction, and the second press core 142 is embedded in the second through groove 1411. The shape and size of the second pressing core 142 are matched with those of the second through groove 1411, and when the second driving part 152 drives the second pressing core 142 to extend out of the molding surface of the first pressing core 141, the second pressing core 142 slides in the second through groove 1411 so as to realize guiding. Similar to the upper die 120, in the use state, the molding surface of the first press core 141 is the bottom surface thereof.

The second driving part 152 drives the second press core 142 to extend beyond the molding surface of the upper die 120 by a distance greater than the distance by which the first driving part 151 drives the first press core 141 to extend beyond the molding surface of the upper die 120, thereby realizing that the second press core 142 extends beyond the molding surface of the first press core 141. Thus, pits with different depths can be formed on the material, specifically, the pit depth formed by the second pressing core 142 is greater than the pit depth formed by the first pressing core 141.

Specifically, in some embodiments, the first driving portion 151 and the second driving portion 152 may each be an air cylinder, and the movement stroke of the telescopic rod of the second driving portion 152 is larger than that of the first driving portion 151, so that the second pressing core 142 can extend out of the molding surface of the first pressing core 141.

It should be noted that the nitrogen spring has a relatively high rigidity, and the force required for compression and retraction is far greater than the force required for forming the pit in the material, so that the nitrogen spring is not immediately held against and retracted after the pressing core is contacted with the material, but is slowly retracted after the pit is pressed out of the material, and the nitrogen spring can be avoided when the pit is gradually formed.

With continued reference to fig. 2, 3 and 5, as described above, the telescopic end of the first driving portion 151 passes through the upper die frame 110 and is fixedly connected to the first pressing core 141, and the telescopic end of the second driving portion 152 passes through the upper die frame 110 and is fixedly connected to the second pressing core 142. In addition, the first pressing core 141 is fixedly connected with a first stop lever 172, a boss is disposed on an outer circumferential surface of one end of the first stop lever 172 away from the first pressing core 141 to form a stepped stop structure, a stepped hole is disposed at the chute 112 of the upper die frame 110, and the distance of the first pressing core 141 extending outwards can be limited by matching the stepped hole with the boss. Similarly, the second pressing core 142 is also fixedly connected with a second limiting rod 173, and a step hole is formed at the chute 112 of the upper die frame 110, and the distance that the second pressing core 142 extends outwards can be limited by matching the step hole with the boss.

Preferably, the first stop lever 172 and the second stop lever 173 are provided in plurality to increase stability of the stop structure.

Specifically, the first through groove 122 is disposed in the central region of the upper die 120, and the second through groove 1411 is disposed in the central region of the first pressing core 141. Thus, two pits of different depths are formed in a stepped hole-like shape, with the pit depth in the central region being greater than the depth of the edge pit surrounding it.

Of course, in other embodiments, the position of the first pressing core 141 embedded in the upper die 120 and the position of the second pressing core 142 embedded in the first pressing core 141 may be selected, and may be specifically adjusted according to the shape to be formed.

Referring to fig. 3 and 4, in some embodiments, a side of the lower mold 220 facing away from the lower mold frame 210 is provided with a plurality of positioning columns 230 protruding along a first direction, and the plurality of positioning columns 230 are disposed around the lower mold 220 in a circle to limit the position of the material; the upper die 120 is provided with a plurality of positioning holes 180, and a plurality of positioning posts 230 can be inserted into the plurality of positioning holes 180 in a one-to-one correspondence manner during die assembly.

The material is placed in the space, and the plurality of positioning columns 230 are propped against the edge of the material to limit the material from shifting, so that the stamping precision is ensured. The side wall of the upper die 120 is provided with a plurality of positioning holes 180 corresponding to the positioning columns 230 one by one, and when the die is closed, each positioning column 230 is inserted into one corresponding positioning hole 180, so that avoidance is realized.

Referring to fig. 3 and 4, in some embodiments, one of the upper mold frame 110 and the lower mold frame 210 is provided with a guide post 240 protruding in a first direction, and the other is provided with a guide groove 190 recessed in the first direction, and the guide post 240 is inserted into the guide groove 190 and slidably engaged with the guide groove.

Specifically, in the embodiment shown in the drawings, the upper mold frame 110 is provided with the guide groove 190, and the lower mold frame 210 is provided with the guide post 240, and the sliding fit is achieved through the insertion of the two, so that the position alignment between the upper mold assembly 100 and the lower mold assembly 200 is achieved.
