Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, and in particular to a punching mold and a punching press. Background Technology

[0002] As a support component, switch brackets need to fulfill the functions of support, limiting, and fixing. Their diverse shapes and structures often require punching holes on different planes. Punching technology can efficiently create holes of the required shapes on sheet metal to meet the functional requirements of switch brackets in terms of ventilation, heat dissipation, and connection. When punching switch brackets using molds, single-punch-one-hole dies are often used to ensure processing accuracy and flexibility; however, only one hole can be processed at a time, resulting in long production cycles, low efficiency, and relatively high processing costs per unit. Existing dies that process multiple holes at once can complete multiple hole processing in a single punch; however, they are suitable for mass production of products with fixed hole positions, lacking flexibility. Furthermore, existing punching dies are all one-piece, requiring replacement of the entire piece after wear, leading to high operating costs. Utility Model Content

The punching die includes: an upper mounting assembly 100 connected to the power output end of the processing equipment; an upper fixing plate 200 connected to the end of the upper mounting assembly 100 away from the processing equipment, the upper fixing plate 200 having multiple mounting holes 210; a material ejection assembly 300 connected to the end of the upper fixing plate 200 away from the upper mounting assembly 100; and a punch 600, one end of which... The punch 600 is snapped into the mounting hole 210, with the other end extending to the outside of the ejector assembly 300; the lower mounting assembly 400 is fixed to the processing table of the processing equipment; the split lower die 500 includes a lower die body 510 and a lower mounting block 520, the lower die body 510 having a punch hole that mates with the punch 600; the lower mounting block 520 having a mounting groove, the lower die body 510 being snapped into the mounting groove; the lower die body 510 and the lower mounting block 520 are respectively connected to the lower mounting assembly 400. By setting multiple mounting holes 210 on the mounting plate, and then inserting punches 600 into the mounting holes 210 according to actual processing requirements, multiple holes can be processed in one stamping, greatly improving production efficiency: reducing production time and labor costs, lowering the processing cost of a single product, and improving the adaptability of the mold; by setting a split lower mold 500, when the lower mold is damaged during the stamping process, only the lower mold body 510 needs to be replaced, reducing maintenance costs, improving maintenance efficiency, and enhancing the overall lifespan of the mold.

[0024] Furthermore, in this embodiment, the punch holes on the lower mold body 510 correspond radially to the mounting holes 210 on the upper fixed plate 200, so as to adapt to the situation where punches 600 of different specifications are snapped on the upper fixed plate 200, thereby improving the adaptability of the mold.

[0025] See Figure 2 and Figure 4 , Figure 4 This is a schematic diagram of the installation of the punch 600 of a punching die in this embodiment.

[0026] In this embodiment, three punches 600 are snapped onto the upper fixing plate 200. Each punch 600 has a snap-fit ​​portion at its upper end. After the punch 600 is inserted into the hole of the mounting hole 210, its mounting surface is 1mm to 1.5mm higher than the surface of the upper fixing plate 200 to ensure that the upper mounting plate 110 presses the punch 600 firmly and prevents loosening. During use, three holes can be processed in a single punching operation, greatly improving production efficiency and reducing production time and labor costs. In other embodiments, different numbers of punches 600 can be snapped onto the upper fixing plate 200 according to actual processing requirements.

[0027] See Figure 2 Furthermore, in this embodiment, the punching die also includes a guide assembly to prevent deviation during punching. The guide assembly includes: a guide post 710, one end of which is connected to the upper fixed plate 200, and the other end of which extends to the outside of the ejector assembly 300; and a guide sleeve 720, fixed to the lower mounting block 520, the vertical position of which corresponds to the guide post 710. Specifically, two guide posts 710 and two guide sleeves 720 are provided to ensure that the die does not deviate during punching and to improve the accuracy of the punching process.

[0028] See Figure 2 and Figure 3 Furthermore, in this embodiment, the guiding assembly also includes a guide pin 730, which is fixed to the upper end of the lower mold body 510 and the upper end of the lower mounting plate 410; the ejector plate 310 is provided with a guide hole that cooperates with the guide pin 730. The guide pin 730 can ensure uniform mold clearance, improve mold closing accuracy, reduce part wear, extend mold life, and at the same time ensure product quality and reduce scrap rate.

Specifically, the die shank 120 is mounted on the fixed slider of the punch press.

[0030] See Figure 2 Furthermore, in this embodiment, the ejector assembly 300 includes: an ejector plate 310 connected to the upper fixing plate 200; and elastic members 320 disposed between the ejector plate 310 and the upper fixing plate 200. Specifically, the elastic members 320 are ejector adhesive, and four are provided. During downward pressing, the ejection is completed by the elasticity of the elastic members 320 between the upper fixing plate 200 and the ejector plate 310.

[0031] See Figure 2 Furthermore, the upper mounting assembly 100 also includes a cylindrical pin 130, one end of which is inserted into the upper mounting plate 110, and the other end of which passes through the upper fixing plate 200 and connects to the ejector plate 310. The cylindrical pin 130 is used to determine the relative position of each part in the mold, ensuring that each component is accurately aligned during each assembly.

[0032] Preferably, the upper mounting plate 110, the upper fixing plate 200, and the ejector plate 310 are fixedly connected by bolts.

[0033] See Figure 3 Furthermore, the lower mounting assembly 400 includes a lower mounting plate 410, which is fixed to the processing table of the processing equipment by bolts; the lower mounting plate 410 is provided with through holes corresponding to the punch holes for protecting the punch.

[0034] Preferably, the lower mold body 510 and the lower mounting block 520 are respectively connected to the lower mounting plate 410 by bolts. The lower mold body 510 is a vulnerable part. When replacing it, only the lower mold body 510 needs to be removed, which reduces maintenance costs, improves maintenance efficiency, and enhances the overall life of the mold.

[0035] See Figure 3 Furthermore, the mounting groove is a dovetail groove. The dovetail groove structure has high rigidity and stability, can withstand large loads and inertial forces, and maintains a stable working state under high-speed movement and heavy load conditions, which can ensure that the lower die body 510 and the lower mounting plate 410 do not separate during stamping.
