Description

Technical Field

[0001] This utility model relates to the field of stamping dies, and in particular to a quick connection structure for quick die changing. Background Technology

[0002] Stamping dies are process equipment that uses presses and stamping equipment to apply pressure to metal or non-metal sheets, causing them to separate or undergo plastic deformation.

[0003] Existing technologies, such as the utility model patent with publication number CN205115789U, disclose a quick mold change structure, which includes a pressure plate and a connecting plate. This quick mold change structure is designed with a detachable connection between the pressure plate and the connecting plate. The pressure plate and the connecting plate are connected by a first opening that engages with a limiting pin. When the limiting pin is extended by a limiting drive device, the pressure plate can be inserted. After insertion, the pressure plate is pushed towards the connecting plate, causing the limiting pin to enter below the second opening. Controlling the limiting drive device then retracts the limiting pin, thus clamping and limiting the pressure plate. When removal is required, the limiting drive device extends the limiting pin, pulling out the pressure plate and removing it downwards. This quick mold change structure is easy to install and disassemble, improving mold change efficiency and thus production efficiency.

[0004] The inventors discovered the following problems in their daily work when using and replacing molds: In stamping production, the quick and reliable fixing of molds and stamping equipment is a key link to ensure efficiency and operational safety. However, the traditional fixing methods such as bolt fastening or pressure plate clamping that are widely used at present have cumbersome operation steps, are time-consuming, and rely on additional tools. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of low work efficiency in mold changing operations in existing technologies.

[0006] To solve the above technical problems, this utility model provides a quick connection structure for quick mold changing, comprising: a machine body and two mold bodies. A spindle is mounted on the surface of the machine body, and a worktable is fixedly connected to the surface of the machine body at a position corresponding to the spindle. Adjustment structures are provided on the sides of the worktable and the spindle that are close to each other. Each adjustment structure includes a fixed frame, and the two fixed frames are respectively fixedly connected to the spindle and the worktable. An adjustment frame is slidably connected to the outer surface of the fixed frame. A positioning rod is threaded into one side of the adjustment frame, and a [missing information] is provided on the side of the fixed frame near the positioning rod. Two positioning holes are provided, one of which has its inner wall slidably connected to a positioning rod. Several reserved slots are provided on both sides of the fixed frame, and an installation rod is slidably connected to the inner wall of the reserved slot. A spring is fitted on the arc surface of the installation rod, and the two ends of the spring are fixedly connected to the installation rod and the fixed frame, respectively. A support rod is fixedly connected to the end of the installation rod away from the fixed frame, and the support rod is slidably connected to the inner wall of the adjusting frame. The inner wall of the fixed frame is slidably connected to the mold body. Several mounting holes are provided on both sides of the mold body, and the inner walls of the mounting holes are slidably connected to the installation rod.

[0007] The effect achieved by the above components is that by using the adjustment frame, several mounting rods can be moved into or out of the mounting holes at the same time, so that the mold body and the fixed frame can be easily disassembled and assembled, improving the work efficiency of replacement operations.

[0008] Preferably, the inner wall of the adjustment frame includes an inclined portion, which is located on the side of the adjustment frame closer to the mold body.

[0009] The effect achieved by the above components is that the inclined part of the inner wall of the adjustment frame simultaneously squeezes several support rods, causing several support rods and mounting rods to move simultaneously.

[0010] Preferably, two sliding rods are fixedly connected to both sides of the fixed frame, and the arc surfaces of the two sliding rods are slidably connected to the adjustment frame.

[0011] The effect achieved by the above components is to further limit the adjustment frame by means of the slide bar, so that the adjustment frame is more stable when it moves along the fixed frame.

[0012] Preferably, the end of the mounting rod near the mold body is arc-shaped.

[0013] The effect achieved by the above components is that the end of the mounting rod near the mold body is arc-shaped, which makes it easier for the mounting rod to slide into the mounting hole.

[0014] Preferably, an auxiliary structure is provided on one side of the machine body. The auxiliary structure includes a connecting frame, which is fixedly connected to the machine body. A card plate is rotatably connected to the inner wall of the connecting frame. A connecting block is slidably connected to the inner wall of the connecting frame. The inner wall of the connecting block is engaged with the card plate. A movable cargo box is fixedly connected to the side of the connecting block away from the machine body.

[0015] The effects achieved by the above components are as follows: the mobile cargo box is used to store the workpieces, which is convenient for management; the connecting frame and the clamping plate are used to limit the connecting block, thereby fixing the mobile cargo box to one side of the machine body and preventing the mobile cargo box from shifting during operation and affecting the operation.

[0016] Preferably, a handle is rotatably connected to one side of the mobile cargo box, and the handle has a "T" shaped cross-section.

[0017] The effect achieved by the above components is: to rotate and lift the handle, and to use the handle to move the cargo box, making it convenient for the user to operate.

[0018] Preferably, the arc surface of the handle is fixedly connected to two anti-slip sleeves, which are rubber sleeves.

[0019] The effect achieved by the above components is to increase the friction of the handle's arc surface through the anti-slip sleeve, making it easier for the user to operate the handle.

[0020] Compared with related technologies, the quick connection structure for quick mold changing provided by this utility model has the following beneficial effects:

[0021] By setting an adjustment structure and moving the adjustment frame, the inclined part of the inner wall of the adjustment frame, in conjunction with the spring force, simultaneously drives several support rods and mounting rods to move. Several mounting rods limit the mold body, allowing for easy assembly and disassembly between the mold body and the fixed frame. This improves the efficiency of changing the mold body and the machine equipment. The operation is simple and quick, requiring no additional tools.

[0022] By setting up an auxiliary structure, the workpieces are stored in a mobile cargo box, which facilitates management. The connecting frame and the clamping plate limit the connecting block, thereby fixing the mobile cargo box to one side of the machine body and preventing the mobile cargo box from shifting during operation and affecting the operation.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 4 The present invention provides a quick mold connection structure for quick mold changing, comprising: a body 1 and two mold bodies 4. A spindle 2 is mounted on the surface of the body 1. A worktable 3 is fixedly connected to the surface of the body 1 at the position corresponding to the spindle 2. An adjustment structure 5 is provided on the side of the worktable 3 and the spindle 2 that are close to each other. An auxiliary structure 6 is provided on one side of the body 1.

[0032] In the embodiments of this utility model, please refer to Figures 2 to 4The adjusting structure 5 includes a fixed frame 501, with two fixed frames 501 fixedly connected to the spindle 2 and the worktable 3 respectively. An adjusting frame 502 is slidably connected to the outer surface of the fixed frame 501. A positioning rod 503 is threaded into one side of the adjusting frame 502. Two positioning holes 504 are opened on the side of the fixed frame 501 near the positioning rod 503. The inner wall of one of the positioning holes 504 is slidably connected to the positioning rod 503. Several reserved slots 506 are opened on both sides of the fixed frame 501 for pre-drilled grooves. A mounting rod 507 is slidably connected to the inner wall of the groove 506. A spring 508 is fitted onto the arc surface of the mounting rod 507. The two ends of the spring 508 are fixedly connected to the mounting rod 507 and the fixing frame 501, respectively. A support rod 509 is fixedly connected to the end of the mounting rod 507 away from the fixing frame 501. The support rod 509 is slidably connected to the inner wall of the adjusting frame 502. The inner wall of the fixing frame 501 is slidably connected to the mold body 4. Several mounting holes 510 are provided on both sides of the mold body 4. The inner wall of the mold body 4 is slidably connected to the mounting rod 507. Using the adjusting frame 502, several mounting rods 507 can be moved into or out of the mounting hole 510 at the same time, so that the mold body 4 and the fixed frame 501 can be easily disassembled and assembled, improving the work efficiency of replacement. The inner wall of the adjusting frame 502 includes an inclined part, which is located on the side of the adjusting frame 502 close to the mold body 4. The inclined part of the inner wall of the adjusting frame 502 is used to simultaneously press several support rods 509, so that several support rods 509 and mounting rods 507 move at the same time. Two sliding rods 505 are fixedly connected to both sides of the fixed frame 501. The arc surface of the two sliding rods 505 is slidably connected to the adjusting frame 502. The sliding rods 505 further limit the adjusting frame 502, making the adjusting frame 502 more stable when moving along the fixed frame 501. The end of the mounting rod 507 close to the mold body 4 is arc-shaped, which makes it easy for the mounting rod 507 to slide into the mounting hole 510.

[0033] In the embodiments of this utility model, please refer to Figure 5The auxiliary structure 6 includes a connecting frame 61, which is fixedly connected to the machine body 1. A clamping plate 62 is rotatably connected to the inner wall of the connecting frame 61, and a connecting block 63 is slidably connected to the inner wall of the connecting frame 61. The inner wall of the connecting block 63 is engaged with the clamping plate 62. A movable cargo box 64 is fixedly connected to the side of the connecting block 63 away from the machine body 1. The movable cargo box 64 is used to store workpieces for easy management. The connecting frame 61 and the clamping plate 62 limit the connecting block 63, thereby fixing the movable cargo box 64 to one side of the machine body 1 and preventing the movable cargo box 64 from shifting during operation and affecting the operation. A handle 65 is rotatably connected to one side of the movable cargo box 64. The handle 65 has a "T" shaped cross section. Rotating and lifting the handle 65 allows the movable cargo box 64 to be transferred, making it convenient for the user to operate. Two anti-slip sleeves 66 are fixedly connected to the arc surface of the handle 65. The anti-slip sleeves 66 are rubber sleeves. The anti-slip sleeves 66 increase the friction of the arc surface of the handle 65, making it convenient for the user to operate the handle 65.

[0034] The working principle of the quick mold connection structure for quick mold changing provided by this utility model is as follows: By setting the adjustment structure 5, first rotate the positioning rod 503. The positioning rod 503 moves along the adjustment frame 502 away from the fixed frame 501 by means of the thread. The positioning rod 503 moves out of the positioning hole 504, releasing the limitation on the adjustment frame 502. Then, the adjustment frame 502 moves away from the mold body 4. The adjustment frame 502 moves along the fixed frame 501. During this process, the spring 508 in the compressed state always provides the mounting rod 507 with a distance away from the mold. The elasticity of the body 4 causes the mounting rod 507 to drive the support rod 509 to remain against the inner wall of the adjusting frame 502. When the support rod 509 is aligned with the inclined part of the inner wall of the adjusting frame 502, the adjusting frame 502 continues to move. The support rod 509 will gradually move away from the reserved groove 506 along the inclined part, and the mounting rod 507 will gradually move away from the mold body 4 along the reserved groove 506 until the mounting rod 507 is completely disengaged from the mounting hole 510 on the mold body 4, releasing the restriction on the mold body 4. At this time, the positioning rod 503 is rotated in the opposite direction, so that the positioning rod 503 moves closer to the fixed frame 5. Move the 01 direction into the corresponding positioning hole 504 to temporarily limit the adjustment frame 502. Then, the user can remove the fixing frame 501 from the mold body 4 and put in the new mold body 4. Similarly, rotate the positioning rod 503 to release the limitation on the adjustment frame 502. Then, operate the adjustment frame 502 to move towards the mold body 4. The inclined part of the inner wall of the adjustment frame 502 presses the support rod 509, so that the support rod 509 and the mounting rod 507 move towards the mold body 4 as a whole. Continue to move the adjustment frame 502 until the support rod 509 is close to the mold body 4. 09 is fully moved into the reserved slot 506, and the mounting rod 507 is fully moved into the mounting hole 510 on the mold body 4, so that the position of the mold body 4 is fixed. Among them, the inclined part of the inner wall of the adjusting frame 502 is used to simultaneously squeeze several support rods 509, so that several support rods 509 and mounting rod 507 move at the same time. The sliding rod 505 further limits the adjusting frame 502, making the adjusting frame 502 more stable when moving along the fixed frame 501. The end of the mounting rod 507 near the mold body 4 is arc-shaped, which makes it easy for the mounting rod 507 to slide into the mounting hole 510.

[0035] By setting the auxiliary structure 6, the card plate 62 is first rotated away from the connecting frame 61 to open it. Then, the movable cargo box 64 and the connecting block 63 are brought close to the connecting frame 61. When the connecting block 63 is fully moved into the connecting frame 61, the card plate 62 is rotated in the opposite direction to move the card plate 62 into the connecting frame 61. At the same time, the card plate 62 is engaged with the connecting block 63, thereby fixing the movable cargo box 64 to one side of the machine body 1. The handle 65 is rotated and lifted to move the movable cargo box 64, which is convenient for the user to operate. The anti-slip sleeve 66 increases the friction of the arc surface of the handle 65, making it easier for the user to operate the handle 65.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
