Description

Technical Field

[0001] The present application relates to the technical field of mold processing, and in particular to a multi-component synchronous trimming and forming processing mold. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) in cold stamping. They are also called cold stamping dies. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts. Stamping dies are widely used in home appliances, electronic communications, automobiles and other industries. They have a series of advantages such as high efficiency, material saving, and quality assurance. They are an important means of modern industrial production and a direction of technological development.

[0003] At present, when workers need to process multiple parts of different shapes, they usually use multiple stamping equipment to perform the stamping processes separately, and each stamping equipment usually requires a worker to operate it. However, this will increase the factory's labor production costs. Using one worker to operate multiple stamping equipment in sequence will increase the processing and production time of the parts and reduce the efficiency of part processing, which is insufficient. Utility Model Content

[0004] In order to improve the problems caused by stamping of multiple parts, the present application provides a multi-component synchronous trimming and forming processing die.

[0005] The multi-component synchronous trimming and forming processing die provided in this application adopts the following technical solution:

[0007] By adopting the above technical solution, workers first place various part blanks on the multiple stamping convex modules on the lower die base in sequence, and then use the upper die base to drive the multiple stamping concave modules on it to press on the multiple stamping convex modules on the lower die base. Then, workers take out the processed parts through the demolding assembly, thereby realizing the simultaneous processing of multiple parts at one time. The equipment does not require multiple workers to operate during the stamping process, and multiple parts can be processed at one time, which shortens the time for part processing, improves the efficiency of part production, and reduces the cost of part production.

[0008] Optionally, the demolding assembly includes a column arranged on the lower die base, a sleeve is coaxially slidingly sleeved on the column, a demolding sheet is arranged on the sleeve, and the demolding sheet is used to lift the parts; an anti-slip cone is arranged at the end of the column facing away from the lower die base, and the diameter of the anti-slip cone gradually increases from the upper die base to the lower die base; an unlocking cone ring is arranged at the end of the sleeve close to the anti-slip cone, and the diameter of the unlocking cone ring gradually decreases from the upper die base to the lower die base; the maximum diameter of the unlocking cone ring is greater than the maximum diameter of the anti-slip cone; a driving member for driving the sleeve to slide is arranged on the upper die base.

[0009] By adopting the above technical solution, when the parts are processed, the driving member drives the sleeve to slide, and the sleeve drives the demoulding sheet to lift the edge of the parts, so that the processed parts are separated from the stamping convex module, thereby making it easier for workers to take the parts.

[0010] Optionally, the driving member includes an unlocking block arranged on the upper mold base, the unlocking block is provided with a plurality of sliding grooves, the plurality of sliding grooves are evenly arranged circumferentially relative to the axis of the column, a sliding block is slidably arranged in each of the plurality of sliding grooves, the cross-sections of the sliding block and the sliding groove are both T-shaped, a stripping hook is provided on the sliding block, a compression spring is supported between the sliding block and the sliding groove, and the stripping hook is used to hook the unlocking cone ring.

[0011] By adopting the above technical scheme, when the upper die seat is pressed against the lower die seat, the upper die seat drives the stripping hook to approach the anti-stripping cone on the column through the unlocking block, and as the stripping hook continues to move downward, the stripping hook abuts against the inclined surface of the anti-stripping cone and slides with the inclined surface of the anti-stripping cone until the stripping hook breaks away from the anti-stripping cone and abuts against the column, the stripping hook continues to move downward, and the stripping hook abuts against the edge of the unlocking cone ring until the stripping hook abuts against the inclined surface of the unlocking cone ring, during which the compression spring continuously deforms; when the upper die seat is away from the lower die seat, the stripping hook hooks the unlocking cone ring, and the unlocking cone ring drives the stripping piece to rise through the sleeve until the unlocking cone ring abuts against the anti-stripping cone, and as the stripping hook continues to rise, under the limiting action of the anti-stripping cone, the stripping hook disengages from the inclined surface of the unlocking cone ring, and the unlocking cone ring is reset under the action of gravity.

[0012] Optionally, the stamping convex module can be detachably arranged on the lower die base, and the stamping concave module can be detachably arranged on the upper die base.

[0014] Optionally, a pressure sensor electrically connected to a control system is provided on the lower die base, and a pressure groove for installing the pressure sensor is opened on the stamping convex module.

[0015] By adopting the above technical solution, during the process of the upper die seat being pressed against the lower die seat, the sensing end of the pressure sensor abuts against the part, and the pressure sensor feeds back the pressure of the part to the control system, thereby controlling the punching force of the upper die seat on the lower die seat, reducing the possibility of damage to the equipment due to excessive punching force, and helping to extend the service life of the equipment.

[0016] Optionally, a positioning block is detachably provided on the lower die base, a positioning rod is provided on the positioning block, a guiding slope is provided on the positioning rod, and the guiding slope is used to guide the parts to fall.

[0018] Optionally, a micro-pressure cylinder electrically connected to a control system is provided on the upper die base, and the stamping concave module is provided on a piston rod of the micro-pressure cylinder.

[0019] By adopting the above technical solution, workers can adjust the positions of different types of stamping concave modules through the micro-pressure cylinder, so that during the stamping process when the upper die seat is pressed on the lower die seat, multiple parts blanks can be processed simultaneously at one time, and some parts will not be over-stamped.

[0020] Optionally, a discharge plate is provided on the lower die base, and a placement groove for accommodating the discharge plate is opened on the lower die base, and the discharge plate is used to receive waste materials after the parts are cut off.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The worker first places various parts blanks on the multiple stamping convex modules on the lower die seat in sequence, and then drives the multiple stamping concave modules on the upper die seat to press on the multiple stamping convex modules on the lower die seat. Then the worker takes out the processed parts through the demoulding assembly, so as to realize the simultaneous processing of multiple parts at one time. The equipment does not require multiple workers to operate during the stamping process, and multiple parts can be processed at one time, which shortens the time of part processing, improves the efficiency of part production, and reduces the cost of part production;

[0024] 2. When the upper die seat is pressed against the lower die seat, the upper die seat drives the stripping hook to approach the anti-stripping cone on the column through the unlocking block. As the stripping hook continues to move downward, the stripping hook abuts against the inclined surface of the anti-stripping cone and slides with the inclined surface of the anti-stripping cone until the stripping hook is separated from the anti-stripping cone and abuts against the column. The stripping hook continues to move downward and abuts against the edge of the unlocking cone ring until the stripping hook abuts against the inclined surface of the unlocking cone ring. During this process, the compression spring is constantly deformed.

[0025] 3. Through the micro-pressure cylinder, workers can adjust the position of different types of stamping concave modules, so that during the stamping process when the upper die seat is pressed on the lower die seat, multiple parts blanks can be processed simultaneously at one time, and some parts will not be over-stamped.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses a multi-component synchronous trimming and forming processing mold.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The part 0 is placed between the stamping convex module 3 and the stamping concave module 4. The multiple stamping convex modules 3 are different from each other. The stamping convex module 3 on the lower die base 2 is bolted with a pressure sensor 6 electrically connected to the control system. The stamping convex module 3 is provided with a pressure groove 7 for installing the pressure sensor 6.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A positioning block 8 is bolted to the lower die base 2, a positioning rod 9 is welded to the positioning block 8, a guiding slope 10 is provided on the positioning rod 9, and the guiding slope 10 is used to guide the part 0 to fall. A discharge plate 12 is welded on the lower die base 2, and a placement groove 13 for accommodating the discharge plate 12 is provided on the lower die base 2. The discharge plate 12 is used to receive the waste after the part 0 is cut off. A demolding component 5 for demolding the part 0 is arranged between the stamping convex module 3 and the stamping concave module 4.

[0036] The worker first starts the micro-pressure cylinder 11 through the control system. The micro-pressure cylinder 11 adjusts the position of the stamping concave module 4 through its piston rod, and then places various parts 0 blanks on the corresponding stamping convex modules 3 on the lower die base 2 in turn. Under the positioning and guiding action of the positioning rod 9, the part 0 blank falls above the sensing end of the pressure sensor 6.

[0037] Reference Figure 2 , Figure 3 and Figure 4 The demolding assembly 5 includes a column 51 bolted to the stamping convex module 3 on the lower die base 2, a sleeve 52 is coaxially slidably sleeved on the column 51, a demolding sheet 53 is welded on the sleeve 52, and the demolding sheet 53 is used to lift the part 0, and an anti-stripping cone 54 is welded on the end of the column 51 facing away from the lower die base 2, and the diameter of the anti-stripping cone 54 gradually increases from the upper die base 1 to the lower die base 2.

[0038] Reference Figure 2 , Figure 3 and Figure 4 An unlocking cone ring 55 is welded to one end of the sleeve 52 close to the anti-slip cone 54. The diameter of the unlocking cone ring 55 gradually decreases from the upper die base 1 to the lower die base 2. The maximum diameter of the unlocking cone ring 55 is greater than the maximum diameter of the anti-slip cone 54. A driving part 56 for driving the sleeve 52 to slide is arranged on the upper die base 1.

[0039] Reference Figure 2 , Figure 3 and Figure 4 The driving member 56 includes an unlocking block 561 bolted to the upper die base 1, and a plurality of sliding grooves 562 are provided on the unlocking block 561. The plurality of sliding grooves 562 are evenly arranged circumferentially relative to the axis of the column 51, and a sliding block 563 is slidably arranged in each of the plurality of sliding grooves 562. The cross-sections of the sliding block 563 and the sliding groove 562 are both T-shaped, and a stripping hook 564 is welded on the sliding block 563. A compression spring 565 is supported between the sliding block 563 and the sliding groove 562, and the stripping hook 564 is used to hook the unlocking cone ring 55.

[0040] When the upper die base 1 is pressed down on the lower die base 2, the upper die base 1 drives the unlocking block 561 to descend synchronously, and the unlocking block 561 drives the stripping hook 564 to approach the anti-stripping cone 54 on the column 51. As the stripping hook 564 continues to descend, the stripping hook 564 abuts against the inclined surface of the anti-stripping cone 54 and slides with the inclined surface of the anti-stripping cone 54. During this process, the compression spring 565 is compressed until the stripping hook 564 breaks away from the anti-stripping cone 54 and abuts against the column 51, at which time the compression spring 565 resumes its deformation.

[0041] The stripping hook 564 continues to move downward, and abuts against the edge of the unlocking cone ring 55 until the stripping hook 564 abuts against the inclined surface of the unlocking cone ring 55. During this process, the compression spring 565 is compressed again until the stripping hook 564 abuts against the sleeve 52. During this process, the compression spring 565 recovers a certain deformation.

[0042] When the upper die base 1 rises, under the action of the compression spring 565, the stripping hook 564 hooks the contact position between the unlocking cone ring 55 and the sleeve 52. As the upper die base 1 rises, the unlocking cone ring 55 drives the demolding piece 53 to rise through the sleeve 52, and the demolding piece 53 drives the edge of the part 0 to separate from the stamping convex module 3 until the unlocking cone ring 55 is tightly pressed against the anti-stripping cone 54. As the stripping hook 564 continues to rise, under the limiting action of the anti-stripping cone 54, the compression spring 565 is compressed until the stripping hook 564 is separated from the inclined surface of the unlocking cone ring 55, the compression spring 565 resumes its deformation, and the unlocking cone ring 55 is reset under the action of gravity.

[0043] The implementation principle of a multi-component synchronous trimming and forming processing mold in an embodiment of the present application is: the worker first starts the micro-pressure cylinder 11 through the control system, and the micro-pressure cylinder 11 adjusts the position of the stamping concave module 4 through its piston rod, and then places a variety of parts 0 blanks in turn on the corresponding stamping convex modules 3 on the lower die base 2. Under the positioning and guiding action of the positioning rod 9, the part 0 blank falls above the sensing end of the pressure sensor 6.

[0044] When the upper die base 1 is pressed down on the lower die base 2, the upper die base 1 drives the unlocking block 561 to descend synchronously, and the unlocking block 561 drives the stripping hook 564 to approach the anti-stripping cone 54 on the column 51. As the stripping hook 564 continues to descend, the stripping hook 564 abuts against the inclined surface of the anti-stripping cone 54 and slides with the inclined surface of the anti-stripping cone 54. During this process, the compression spring 565 is compressed until the stripping hook 564 breaks away from the anti-stripping cone 54 and abuts against the column 51, at which time the compression spring 565 resumes its deformation.

[0045] The stripping hook 564 continues to move downward, and abuts against the edge of the unlocking cone ring 55 until the stripping hook 564 abuts against the inclined surface of the unlocking cone ring 55. During this process, the compression spring 565 is compressed again until the stripping hook 564 abuts against the sleeve 52. During this process, the compression spring 565 recovers a certain deformation.

[0046] When the upper die base 1 rises, under the action of the compression spring 565, the stripping hook 564 hooks the contact position between the unlocking cone ring 55 and the sleeve 52. As the upper die base 1 rises, the unlocking cone ring 55 drives the demolding piece 53 to rise through the sleeve 52, and the demolding piece 53 drives the edge of the part 0 to separate from the stamping convex module 3 until the unlocking cone ring 55 is tightly pressed against the anti-stripping cone 54. As the stripping hook 564 continues to rise, under the limiting action of the anti-stripping cone 54, the compression spring 565 is compressed until the stripping hook 564 is separated from the inclined surface of the unlocking cone ring 55, the compression spring 565 resumes its deformation, and the unlocking cone ring 55 is reset under the action of gravity.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
