Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and more specifically to a multi-station automotive parts stamping mold structure. Background Technology
[0002] As is generally known, automotive parts stamping dies are stamping tools specifically designed for the mass production of automotive parts. Multi-cavity stamping dies apply pressure to sheet metal, such as steel or aluminum sheets, through the upper die on a press, causing the sheet metal to deform under the structure of the lower and upper dies, thereby obtaining the corresponding automotive parts.
[0003] The processing steps of multi-cavity stamping dies are as follows: the sheet metal is positioned on the multiple cavities of the lower die of the stamping equipment, the press of the equipment is started to drive the upper die to press down and cooperate synchronously with the multiple cavities of the lower die to stamp multiple parts at one time. After the sheet metal is stamped, the springs below the cavities push it out and leave it on the cavities. Finally, the finished parts are taken out from each processing position in sequence.
[0004] After the sheet metal is formed, the multi-cavity stamping die mentioned above does not have a feeding mechanism. After the spring ejector structure below the cavity pushes the finished part away from the cavity, the part will remain on the cavity surface of the lower die. It is necessary to pick up the finished parts corresponding to multiple cavities one by one. This operation process is inconvenient and the part picking efficiency is low. Utility Model Content
[0005] In view of the above-mentioned problems in the prior art, one objective of this utility model is to provide a multi-station automotive parts stamping die structure to solve the above-mentioned shortcomings of the prior art.
[0006] To achieve the above objectives, this utility model provides a multi-station automotive parts stamping die structure, including a stamping equipment body and a lower die, and further including: a blanking rack, which is slidably disposed on the width direction of the lower die; blanking arms corresponding to multiple cavities of the lower die are disposed on the length direction of the blanking rack; a rubber strip is disposed on the inner ring of each blanking arm; a lever is disposed on the blanking rack; when the blanking rack slides, each blanking arm and each rubber strip cooperate to abut against each part.
[0007] Preferably, a guide portion is provided at the center of the lower mold, which slides in conjunction with the unloading frame.
[0008] Preferably, the guide portion is provided with limiting portions, and each limiting portion is specifically a rectangular structure.
[0009] Preferably, the unloading rack is provided with protruding pads that abut against and cooperate with each of the limiting parts.
[0010] Preferably, each of the protruding pads is a cylindrical structure, so that when the material feeder finishes its sliding stroke on the guide portion, each of the protruding pads abuts against each of the limiting portions.
[0011] Preferably, each of the unloading arms has an arc-shaped structure, and its arc-shaped opening is larger than the diameter of each of the parts.
[0012] Preferably, each of the rubber strips has an overall arc-shaped structure, which is adapted to each of the feeding arms.
[0013] Preferably, the lower mold has slots on multiple processing positions corresponding to each of the parts.
[0014] Preferably, each slot is provided with a guide plate, and each guide plate is provided with an arc-shaped portion.
[0015] Preferably, the stamping equipment body is provided with a storage box corresponding to each of the guide plates, and each of the storage boxes has a storage space for placing each of the parts.
[0016] In the above technical solution, the multi-station automotive parts stamping die structure provided by this utility model has the following beneficial effects: After the upper die on the stamping equipment body stamps multiple cavities on the lower die, multiple parts remain on the cavities. At this time, by sliding the unloading rack with a lever, multiple unloading arms on the unloading rack move synchronously towards the parts remaining on the corresponding cavities. Figure 4 As shown in the status, continue until all finished parts are in contact, and then simultaneously move them off the cavity, as follows. Figure 6 As shown in the diagram, this device, through the corresponding layout of the unloading rack and multiple cavities, enables the unloading of multiple finished products at once, improving the part retrieval efficiency and making the operation process convenient. It reduces or even avoids the problem that parts will remain on the surface of the lower mold cavity, requiring the sequential retrieval of finished parts corresponding to multiple cavities, which is inconvenient and has low part retrieval efficiency.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0021] Please see Figure 1-6 A multi-station automotive parts stamping die structure is proposed to solve the problem that after the sheet metal is formed, the multi-cavity stamping die does not have a blanking mechanism. After the spring ejector structure below the cavity pushes the finished part away from the cavity, the part will remain on the cavity surface of the lower die. It is necessary to pick up the finished parts corresponding to multiple cavities one by one. This operation process is inconvenient and the part picking efficiency is low.
[0022] As a further technical solution proposed in this utility model, the device includes a stamping equipment body 1 and a lower die 5, and further includes: a feeding rack 3, which is slidably disposed on the width direction of the lower die 5; feeding arms 3.1 corresponding to multiple cavities of the lower die 5 are disposed on the length direction of the feeding rack 3; a rubber strip 7 is disposed on the inner ring of each feeding arm 3.1; a lever 3.2 is disposed on the feeding rack 3; when the feeding rack 3 slides, each feeding arm 3.1 and each rubber strip 7 cooperate to abut against each part 6. Specifically, after the upper die (not shown in the figure) on the stamping equipment body 1 stamps multiple cavities on the lower die 5, multiple parts are retained on multiple cavities. At this time, by sliding the feeding rack 3 through the lever 3.2, the multiple feeding arms 3.1 on the feeding rack 3 move synchronously toward the parts 6 retained on the corresponding cavities, such as... Figure 4 As shown in the status, continue until all finished parts 6 are in contact, and then simultaneously move them off the cavity, as shown. Figure 6As shown in the figure, the device realizes the one-time unloading of multiple finished products through the corresponding layout of the unloading rack 3 and the multi-cavity, which improves the part picking efficiency and makes the operation process convenient. It reduces or even avoids the problem that parts will be stuck on the surface of the lower mold cavity, and multiple finished parts corresponding to the cavity need to be picked up one by one. This operation process is relatively inconvenient and the part picking efficiency is low.
[0023] In this embodiment, the number of unloading arms 3.1 on the unloading rack 3 corresponds to the number of cavities (processing positions) on the lower mold 5. The number of cavities on the lower mold 5 is at least two, and the specific number is set according to the needs of those skilled in the art. The multiple unloading arms 3.1 on the unloading rack 3 unload the finished parts that are stuck on the cavities at one time.
[0024] In another embodiment of this utility model, a guide portion 2 is provided at the center of the lower mold 5, which slides in cooperation with the unloading frame 3. Limiting portions 2.1 are provided opposite to each other on the guide portion 2, each limiting portion 2.1 having a rectangular structure. Protruding pads 3.3 are provided opposite to each limiting portion 2.1 on the unloading frame 3, each protruding pad 3.3 having a cylindrical structure. When the unloading frame 3 finishes its sliding stroke on the guide portion 2, each protruding pad 3.3 abuts against each limiting portion 2.1. Furthermore, the sliding cooperation between the guide portion 2 and the unloading frame 3 controls the movement of the unloading frame 3. The precise guiding function ensures that when the unloading rack 3 moves with multiple unloading arms 3.1, it avoids lateral deviation and wobbling, accurately aligning with the parts 6 in each cavity. The rectangular limiting parts 2.1 on the guide part 2 abut against the rubber protruding pads 3.3 on the unloading rack 3, limiting the sliding stroke of the unloading rack 3. When sliding forward or backward, the protruding pads 3.3 stop upon contact with the limiting parts 2.1, preventing the unloading arms 3.1 from sliding excessively or too quickly and colliding with the inner wall of the guide part 2. The elastic cushioning of the rubber material provides protection. Figure 3 As shown in the diagram, the guide part 2 is located at the center of the lower mold 5, which serves as a central support for the unloading rack 3, allowing the unloading rack 3 to slide with more even force.
[0025] In another embodiment of this utility model, each unloading arm 3.1 is specifically an arc-shaped structure, with its arc-shaped opening larger than the diameter of each part 6. Furthermore, the arc-shaped structure of the unloading arm 3.1 allows for precise fitting with the outer contour of the part 6, resulting in a larger contact area and more uniform force distribution. Secondly, the arc-shaped opening is larger than the diameter of the part 6, reserving a reasonable tolerance gap. In some embodiments, after the spring ejects the material, the part 6 may slightly shift on the cavity surface (not absolutely centered). The larger opening can accommodate this slight deviation, and the unloading arm 3.1 can still smoothly fit and move the part 6 without requiring the part 6 to be perfectly precisely positioned. This avoids the unloading arm 3.1 from getting stuck with the part 6 due to slight fluctuations in the size of the part 6 (there are reasonable tolerances in stamped parts) or slight errors in the sliding of the unloading frame 3. During unloading, the arc-shaped opening is larger than the diameter of the part 6, and the unloading arm 3.1 can quickly "wrap" around the outside of the part (or fit the edge of the part) when moving, contacting and pushing the part 6 without precise alignment.
[0026] In another embodiment of this utility model, each rubber strip 7 has an overall arc-shaped structure, which is adapted to each feeding arm 3.1, such as... Figure 5 and Figure 6 As shown in the diagram, each rubber strip 7 is an arc-shaped structure adapted to the unloading arm 3.1. Its arc-shaped contour is completely fitted to the unloading arm 3.1, which can maximize the contact area between the rubber strip 7 and the part 6. The flexible characteristics of the rubber material combined with the uniform force distribution advantage of the arc-shaped adaptation can avoid hard friction between the unloading arm 3.1 and the part 6, avoid scratches and deformation of the part surface, and absorb the impact force of the push through elastic buffering, weakening or even preventing the part 6 from being bounced away due to excessive pushing force of the unloading frame 3.
[0027] In another embodiment of this utility model, slots 5.1 corresponding to each part 6 are provided on multiple processing positions of the lower mold 5. Each slot 5.1 is provided with a guide plate 4, and each guide plate 4 is provided with an arc-shaped portion 4.1. Further, the slots 5.1 are used to position the guide plate 4 corresponding to the part 6, which can quickly define the placement area of the guide plate 4. After the guide plate 4 and the slot 5.1 are inserted and engaged, after the unloading arm 3.1 moves the part 6, the part 6 can slide onto the guide plate 4 on the arc-shaped portion 4.1. The arc-shaped portion 4.1 can guide the part 6 to smoothly slide out of the cavity along the arc-shaped trajectory, such as... Figure 6 The status is as shown.
[0028] In another embodiment of this utility model, the stamping equipment body 1 is provided with a storage box 1.1 corresponding to each guide plate 4. Each storage box 1.1 has a storage space for placing each part 6. Furthermore, the stamping equipment body 1 is provided with a storage box 1.1 corresponding to each guide plate 4. Each storage box 1.1 has a storage space for loading the part 6. The storage box 1.1 is precisely matched with the guide trajectory of the guide plate 4 to realize the process of unloading, guiding and storing the part 6. The part is picked up by sliding the unloading rack 3, avoiding direct contact between the manual and the mold to pick up the part, thus reducing safety hazards.
[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
