Abstract
Description
Technical Field
[0001] The utility model relates to the field of molds, in particular to a hardware bending mold. Background Art
[0002] The current market competition is fierce, the supply cycle is short, and the product updates are fast. Conventional hardware mold structures are not suitable for docking with automated production lines.
[0003] like Figure 1 The figure shows an existing hardware mold, which includes a first mold group and a second mold group. The first mold group includes a cover plate 11, an upper mold base 12, an upper pad 13, an upper clamping plate 14, a stripping plate 15, and a stripping plate 16. The second mold group includes a lower support plate 21, a lower pad 22, a lower mold base 23, a lower pad 24, and a lower mold plate 25. The first mold group and the second mold group move relative to each other to achieve mold closing or mold opening. Specifically, as shown in FIG. Figure 1 The figure shows the process from the closed mold state to the open mold state, wherein, when the upper clamping plate 14, the stripper plate 16 (i.e., the upper template) and the lower template 25 are in the open mold state, the upper work surface of the mold moves upward, the spring pushes out the stripper plate 16 and separates it from the upper clamping plate 14, the bending core (not shown in the figure) retracts, the upper work surface continues to move upward, the stripper plate 16 separates from the lower template 25, and the material strip floats and feeds forward; in the closed mold state, the upper work surface of the mold moves downward, the stripper plate 16 fits with the lower template 25, the upper clamping plate 14 fits with the stripper plate 16, and the bending core extends out to bend the material strip.
[0004] like Figure 2 The figure shows a schematic diagram of the strip processing of existing metal bending molds. During the strip processing process, the strip needs to be cut and formed simultaneously to ensure that the strip has a certain structural strength. Because the stripper plate 16 and the lower mold plate 25 are separated from each other during the mold closing and opening processes, the strip is in a suspended floating state. The strip is fed in this floating state. Cutting and forming simultaneously can ensure that the strip has sufficient structural strength and does not deform. This results in more steps in the mold processing process, increases the production cycle, increases costs, and limits efficiency. Utility Model Content

DETAILED DESCRIPTION
[0037] The above embodiments given in conjunction with the accompanying drawings further illustrate the specific implementation of the hardware bending mold of the present utility model. The hardware bending mold of the present utility model is not limited to the description of the following embodiments.
[0038] like Figure 3-4As shown, this embodiment provides a metal bending mold, including: a first mold group 100 and a second mold group 200, the first mold group 100 includes a first template 110, a first clamping plate 120, a first cover plate 140, a first core 150 and a first core connector 160, the first core 150 is connected to the first clamping plate 120 through the first core connector 160, the first mold group 110 is provided with a first guide hole for guiding the first core 150, a first guide rod 170 is provided between the first mold group 110 and the first clamping plate 120, and the first clamping plate 120 can be driven by the first clamping plate 120. The second die set 200 slides relative to the first die plate 110 through the first guide rod 170; the second die set 200 includes a second die plate 210, a second clamping plate 220, and a second cover plate 240; a material processing gap h is provided between the first die plate 110 and the second die plate 210 for passing the material strip; during the mold closing or mold opening process, the first die plate 110 and the second die plate 120 remain fixed, and the first clamping plate 120 is driven to move relative to the first die plate 110, driving the first core 150 to act on the preset bending area of the material strip to bend the material strip or to detach the material strip after bending. The first clamping plate 120 drives the first core 150, which serves as the bending core, to bend the material strip, so that during the material strip feeding process, the material strip does not need to float, but only needs to move in a plane.
[0039] In this embodiment, a first pad 130 may be further provided between the first cover plate 140 and the first clamping plate 120 . The first clamping plate 120 may be driven directly by a driving device, or by the driving device driving the first cover plate 140 .
[0040] In this embodiment, the first module 100 can be an upper module or a lower module. Similarly, the second module 200 can be an upper module or a lower module.
[0041] In a further embodiment, the second module further includes: a second core 250 and a second core connector 260, the second core 250 is connected to the second clamping plate 220 through the second core connector 260, the second template 210 is provided with a second guide hole for guiding the second core 250, and a second guide rod 270 is provided between the second template 210 and the second clamping plate 220, and the first clamping plate 120 can be driven to slide relative to the first template 110 through the second guide rod 170; during the process of closing or opening the mold, the first template 110 and the second template 210 remain in a fixed state, and the first clamping plate 120 and the second clamping plate 220 are driven to move relative to the first template 110 and the second template 210, and drive the first core 150 and the second core 250 to act on the preset area of the bending strip on the material strip to bend the material strip or detach from the material strip after bending. The second core 250 serving as a bending core is driven by the second clamping plate 220 to bend the material strip, so that during the material strip feeding process, the material strip does not need to float but only needs to move in a plane.
[0042] Similarly, a second pad 230 is provided between the second splint 220 and the second cover plate 240. The second splint 220 can be driven directly by a driving device, or the second cover plate 240 can be driven by the driving device. Taking the second cover plate 240 as an example, the second cover plate 240 is provided with a structure for transmission connection of the driving device.
[0043] In this embodiment, the first die set 100 is further provided with a first pressing blade 180, which is connected to the first clamping plate 110 via a first pressing blade connector 190. When the first core 150 is pressed down for bending, the first pressing blade 180 presses the material strip tightly to prevent the material strip from deforming abnormally during the bending process.
[0044] Furthermore, the first pressing blade connecting member 190 is an axially retractable elastic device, which can ensure sufficient pressure and prevent damage to the material strip.
[0045] Specifically, such as Figure 6-7 As shown, the first press blade connector 190 includes a first connector 191, a sleeve 192, a shaft 193, a second connector 194, and a spring 195. The first connector 191 is connected to one end of the sleeve 192, the shaft 193 is slidably disposed within the sleeve 192, and the spring 195 is sleeved outside the sleeve 192. The two ends of the spring 195 are limited by the first connector 191 and the second connector 194. When the mold is closed, the first connector 191 is pressed downward, causing the spring 195 to compress, causing the second connector 194 to elastically act on the first press blade 180 to compress the material strip.
[0046] Correspondingly, the second module 200 is also provided with a second pressing knife 280, which is connected to the second clamping plate 210 through a second pressing knife connecting member 290. Similarly, the second pressing knife connecting member 290 is also an axially retractable elastic device, and its structure is the same as that of the first pressing knife connecting member 190, which will not be repeated here.
[0047] In this embodiment, the first template 110 is provided with a material-receiving boss 111, and the second template 210 is provided with a material-supporting boss 211. The material strip processing gap h is formed by the gap between the material-receiving boss 111 and the material-supporting boss 211. The material-receiving boss 111 and the material-supporting boss 211 only support the middle of the material strip, thereby providing sufficient operating space for the forming core. The material-supporting boss 211 forms a support for the material strip, so that the material strip can be directly translated during the feeding process. The gap between the material-receiving boss 111 and the material-supporting boss 211 is very small, just enough for the material strip to pass through, thereby ensuring that the material strip will not be suspended or bent during translation, and the feeding accuracy is high.
[0048] In this embodiment, the first guide rod 170 is provided with a first limiting post 171 for limiting the sliding distance of the first clamping plate 120, and the second guide rod 270 is provided with a second limiting post 271 for limiting the sliding distance of the second clamping plate 220. The limiting posts 171 can limit the sliding distance of the molding core, thereby ensuring the accuracy of the molding strip.
[0049] Furthermore, the first template 110 and the second template 210 are locked and fixed by a locking plate 300 to fix the material strip processing gap h, thereby ensuring the accuracy of material strip feeding and the precision of the processing process.
[0050] like Figure 3-4 As shown, the grinding tool processing process of this embodiment is as follows:
[0051] In the closed mold state, the first clamping plate 120 and the second clamping plate 220 move relative to each other and close. Driven by the first clamping plate 120, the cutter head of the first core 150 descends to the processing gap h and acts on the material strip to complete the bending process. Driven by the second clamping plate 220, the cutter head of the second core 250 rises to the processing gap h and acts on the material strip to cooperate with the first core 150 to complete the bending process.
[0052] In the mold opening state, the first template 110 and the second template 210 are fixed in position, the first clamp 120 and the second clamp 220 move relative to each other and separate, the first core 150 is driven by the first clamp 120, and the cutter head of the first core 150 rises and leaves the processing gap h area, and the second core 250 is driven by the second clamp 220, and the cutter head of the second core 250 descends and leaves the processing gap h area, and the material belt can be fed in a horizontal manner under the support and limitation of the material supporting boss 211 and the material resisting boss 111.
[0053] In this embodiment, the positions of the first template 110 and the second template 210 are fixed to be in a processing gap state, and the first core 150 and / or the second core 250 are driven by the first clamping plate 120 and the second clamping plate 220 to process the material strip. In this way, the material strip does not need to float during the feeding process, but only needs to move in a plane. Figure 5 As shown, compared with the traditional processing method, the trimming process can be omitted, that is, the entire process reduces the trimming process steps, shortens the production cycle, reduces production costs, and improves production efficiency.

[0055] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
