Description

Technical Field

[0001] This utility model relates to the field of metal stamping die technology, specifically a metal stamping die that is easy to stack. Background Technology

[0002] Metal stamping dies are essential process equipment used in industrial production to form sheet metal parts, and are widely used in the automotive, home appliance, electronics, and aerospace industries. In actual production, to make full use of workshop space, improve equipment efficiency, and facilitate die management and turnover, it is often necessary to stack and store multiple independent stamping dies.

[0003] Currently, common stamping die stacking methods rely primarily on simple stacking, lacking effective positioning and connection structures. During stacking, the upper and lower dies often rely solely on the planar contact of the dies themselves for support, lacking reliable lateral and longitudinal positioning. This results in poor stacking stability, making them prone to slippage, misalignment, or even tipping over during handling or exposure to vibration, posing significant safety hazards. Furthermore, when retrieving or lifting stacked dies, it is typically necessary to first lift the upper die and then the lower die, a cumbersome and inefficient process that increases the workload for workers.

[0004] To address this, we propose a metal stamping die that is easy to stack. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a conveniently stackable metal stamping die. By setting complementary positioning pins and pin holes on the upper and lower die bases, precise stacking positioning is achieved. Furthermore, the upper and lower die bases are locked together as a whole using a quick-release connecting arm. This effectively solves the two core problems of unstable stacking and cumbersome handling of existing stamping dies, thus effectively addressing the issues in the background technology.

[0006] (II) Technical Solution To achieve the above objectives, the technical solution adopted by this utility model is as follows: a metal stamping die that is easy to stack, comprising an upper die base and a lower die base. The upper die base has protruding positioning pins at the four corners of its top surface for positioning and engaging with the upper die. The lower die base has recessed positioning pin holes at the four corners of its bottom surface for positioning and engaging with the lower die. The positions and shapes of the protruding positioning pins and the recessed positioning pin holes are adapted to each other, so that when multiple stamping dies are stacked, the recessed positioning pin holes of the upper die can be fitted onto the protruding positioning pins of the lower die. The middle portion of the outer surface at both ends of the upper die base... A first insertion slot is provided, and a second insertion slot is provided in the middle of the outer surfaces of both ends of the lower mold base. A transverse limiting hole is provided in the middle of the left and right ends of the upper outer surface of the upper mold base. The transverse limiting hole extends to the upper part of the first insertion slot. A connecting arm is connected between the two ends of the upper mold base and the two ends of the lower mold base. A second insertion block is fixedly installed at the bottom of the inner wall of the connecting arm, and a first insertion block is fixedly installed at the upper part of the inner wall of the connecting arm. A snap-fit ​​assembly is provided on the upper part of the first insertion block. The snap-fit ​​assembly includes an installation cavity, a guide ring, a limiting block, a compression spring, and a snap-fit ​​post.

[0007] Preferably, the second plug-in block and the second plug-in slot are plugged into each other.

[0008] Preferably, the outer wall of the first plug-in block and the first plug-in groove are plugged into each other.

[0009] Preferably, the mounting cavity is formed inside the first plug-in block, the guide ring is fixed in the middle of the upper outer surface of the first plug-in block, and the lower end of the guide ring extends through to the middle of the upper end of the mounting cavity.

[0010] Preferably, the snap-fit ​​post penetrates the guide ring, and the outer wall of the snap-fit ​​post is slidably connected to the inner wall of the guide ring. The snap-fit ​​post is fixed to the middle of the upper outer surface of the limiting block, and the compression spring is fixed between the lower outer surface of the limiting block and the bottom of the mounting cavity. Both the limiting block and the compression spring are located in the mounting cavity. The outer wall of the limiting block is slidably connected to the mounting cavity, and the lower outer surface of the limiting block is elastically connected to the bottom of the mounting cavity through the compression spring.

[0011] Preferably, after the first plug-in block is plugged into the first plug-in slot, the upper part of the snap-fit ​​post is snapped into the lateral limiting hole.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a metal stamping die that is easy to stack, and has the following beneficial effects: 1. This convenient stackable metal stamping die, by setting a protruding positioning pin on the top surface of the upper die base and a matching recessed positioning pin hole on the bottom surface of the lower die base, enables the upper and lower dies to automatically and accurately fit and position themselves when stacked; this effectively overcomes the problem of poor stability caused by traditional stacking relying solely on planar contact.

[0013] 2. This conveniently stackable metal stamping die, through a unique connecting arm and snap-fit ​​component design, firmly connects the upper and lower die bases into a whole when the die is closed; when picking up the stacked dies, there is no need to perform the cumbersome steps of "lifting the upper die first and then lifting the lower die", the entire die set (upper and lower die bases) can be lifted and transported directly as a whole; reducing the number of lifting operations, simplifying the operation process, and improving the efficiency of die turnover and loading / unloading.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-5As shown, this utility model provides a conveniently stackable metal stamping die, including an upper die base 1 and a lower die base 2. The upper die base 1 has protruding positioning pins 3 fixedly arranged at the four corners of its top surface, while the lower die base 2 has recessed positioning pin holes (not individually labeled in the figure, but can be found in the appendix of the instruction manual) at the four corners of its bottom surface that match the position and shape of the protruding positioning pins 3. Figure 5 As can be seen, when multiple stamping dies are stacked, the recessed positioning pin hole on the bottom surface of the lower die base 2 of the upper die can be precisely fitted onto the protruding positioning pin 3 on the top surface of the upper die base 1 of the lower die, thereby achieving automatic centering and longitudinal positioning when the upper and lower dies are stacked, effectively preventing lateral slippage during stacking and improving the stability of the stack.

[0022] To securely connect the upper mold base 1 and the lower mold base 2 into a single unit when the mold is closed, facilitating mold turnover and hoisting, a first insertion groove 6 is provided in the middle of the outer surface at both ends of the upper mold base 1, and a second insertion groove 7 is provided in the middle of the outer surface at both ends of the lower mold base 2. A transverse limiting hole 5 is also provided in the middle of the left and right ends of the upper outer surface of the upper mold base 1, extending through to the upper part of the first insertion groove 6. The upper mold base 1 and the lower mold base 2 are connected at both ends by a connecting arm 4. A second insertion block 9 is fixedly installed on the bottom of the inner wall of the connecting arm 4, and a first insertion block 8 is fixedly installed on the upper part of its inner wall.

[0023] A snap-fit ​​assembly 10 is provided on the upper part of the first plug-in block 8. Specifically, the snap-fit ​​assembly 10 includes a mounting cavity 11 opened inside the first plug-in block 8, a guide ring 12 fixed to the middle of the upper outer surface of the first plug-in block 8 (the lower end of the guide ring 12 extends to the middle of the upper end of the mounting cavity 11), a limiting block 13 located in the mounting cavity 11, a compression spring 14 installed between the lower outer surface of the limiting block 13 and the bottom of the mounting cavity 11, and a snap-fit ​​post 15 fixed to the middle of the upper outer surface of the limiting block 13. The snap-fit ​​post 15 passes through the guide ring 12, and its outer wall is slidably connected to the inner wall of the guide ring 12. The outer wall of the limiting block 13 is also slidably connected to the inner wall of the mounting cavity 11. Under the elastic force of the compression spring 14, the limiting block 13 tends to move upward, thereby causing the upper part of the snap-fit ​​post 15 to protrude from the upper surface of the first plug-in block 8 under normal conditions.

[0024] The installation process of connecting arm 4 is as follows: During installation, press the upper end of the locking post 15 with your finger. The locking post 15 slides downward under the guidance of the guide ring 12, and drives the limiting block 13 to move downward in the mounting cavity 11. At the same time, the compression spring 14 is compressed and stores energy. Maintaining this state, align the first insertion block 8 on the connecting arm 4 and insert it into the first insertion slot 6 of the upper mold base 1, and at the same time align the second insertion block 9 and insert it into the second insertion slot 7 of the lower mold base 2. When the first insertion block 8 is fully inserted into the first insertion slot 6, and the locking post 15 moves to the position aligned with the transverse limiting hole 5, the compressed spring 14 releases energy, pushing the limiting block 13 upward, thereby driving the upper part of the locking post 15 to engage in the transverse limiting hole 5. Through this locking action, the connecting arm 4 is reliably locked between the upper mold base 1 and the lower mold base 2, connecting the two into a stable whole.

[0025] When it is necessary to disassemble the connecting arm 4, simply press the locking post 15 again to make its upper end exit the lateral limiting hole 5, and the first plug block 8 can be pulled out from the first plug slot 6. At the same time, the second plug block 9 also disengages from the second plug slot 7, thereby removing the connecting arm 4.

[0026] The working principle of this utility model is as follows: 1. Stacking and storage: When multiple molds need to be stacked, the mold units can be stacked quickly and accurately by using the cooperation of the raised positioning pin 3 and the recessed positioning pin hole, ensuring the stability of the stack.

[0027] 2. Overall hoisting: When a mold needs to be retrieved or transferred, it is no longer necessary to first hoist the upper mold and then the lower mold as in the traditional method. Since the connecting arm 4 has locked the upper mold base 1 and the lower mold base 2 into a whole, the entire mold can be hoisted as a unit directly by the hoisting equipment, which greatly simplifies the operation process and improves work efficiency.

[0028] 3. Mold usage: When the mold needs to be put on the machine for stamping operations, simply disassemble the connecting arms 4 at both ends as described above to carry out normal mold closing and stamping production.
