Description

Technical Field

[0001] This utility model relates to a stamping die, specifically a die base and a stamping die with the die base. Background Technology

[0002] Stamping dies are specialized process equipment used for cold stamping. Their core function is to apply pressure to metal or non-metal sheets at room temperature, causing them to separate (such as punching or blanking) or undergo plastic deformation (such as bending or stretching), thereby efficiently and accurately manufacturing the required parts or semi-finished products.

[0003] Existing stamping dies have complex structures and unreasonable designs. Their die holders typically only have one forming station, preventing the processing of multiple products simultaneously and resulting in low efficiency. Furthermore, existing stamping dies usually lack clamping devices. During stamping, the pressure from above is applied to the supporting structure at the bottom, causing vibration or slight shaking around the mold cavity, reducing stability. The size of the space within the mold cavity changes within a short period, leading to product deformation or irregular edges after forming, lower yield, and more burrs. Therefore, the inventors have improved the structure of the stamping die and its die holder. Utility Model Content

[0004] The purpose of this utility model is to provide a mold base and a stamping die with the mold base, which has a simple structure and reasonable design. The clamping device can prevent vibration of the lower mold base and its supporting plate and lower mounting plate, ensuring the stability of the main body after mold closing. It avoids product deformation or irregular edges caused by vibration and slight shaking, thus improving the yield rate. The space size inside the mold cavity will not change, thus ensuring the quality of the molded product and reducing the probability of burrs. It solves the problems mentioned in the above technical background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mold base, the mold base including a base body, the base body including a base plate and a plurality of vertical beams fixed to the upper surface of the base plate, a work platform fixed to the upper surface of the plurality of vertical beams, and a plurality of processing and forming work stations set on the work platform.

[0006] A stamping die with the aforementioned die base includes a main body and a clamping device disposed on the main body. The main body is disposed on a base and includes a support plate and a lower die base disposed on the support plate. The support plate is fixed to the upper end face of the worktable. A lower mounting plate and an upper mounting plate located above the lower mounting plate are disposed on the lower die base. A clamping plate is disposed between the lower mounting plate and the upper mounting plate. The installation method between the support plate, the lower die base, the lower mounting plate, the upper mounting plate and the clamping plate is prior art and will not be described in detail here. A top plate is fixed on the top of the clamping plate.

[0007] Preferably, it also includes multiple sets of guiding devices, which are evenly arranged on the main body and fixed to the base. The multiple sets of guiding devices operate together to guide the movement of the main body.

[0008] Preferably, the clamping device includes two cylinders and push plates connected to the output ends of the two cylinders respectively. Both cylinders are fixed on the worktable and are symmetrical about the two ends of the main body.

[0009] Preferably, the two push plates are respectively connected to the two lower mold bases, and the two push plates are distributed at both ends of the lower mold bases. Therefore, the two push plates can press the two lower mold bases together to prevent the lower mold bases and their supporting plates and lower mounting plates from vibrating. Thus, the existence of the pressing device ensures the stability of the main body after mold closing and avoids product deformation or irregular edges caused by vibration and slight shaking.

[0010] Preferably, multiple sealing caps are fixed on the lower end face of the pressure plate, and connecting grooves are formed at both ends of each sealing cap. The multiple sealing caps are located on multiple processing and forming stations respectively.

[0011] Preferably, multiple adapter blocks are fixed inside the lower mold base. The multiple adapter blocks are respectively set below multiple sealing caps, and each adapter block is provided with a protrusion. The protrusion is adapted to two connecting grooves so that the adapter block limits the sealing cap. After the two are combined, they remain relatively stationary, thus ensuring the quality of the molded product and reducing the probability of burrs.

[0012] Preferably, a mold cavity is formed between the support plate, the sealing cover and the adapter block, and the bottom of the adapter block is fixed to the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model provides a mold base, which includes a base body, a base plate and multiple vertical beams fixed to the upper surface of the base plate. A work platform is fixed to the upper surface of the multiple vertical beams, and multiple processing and forming stations are set on the work platform. Therefore, multiple products can be stamped and formed at one time through this mold base, which is beneficial to improving processing efficiency.

[0015] This utility model provides a stamping die with the aforementioned die base. The stamping die includes a main body and a clamping device disposed on the main body. The overall structure is simple and reasonably designed. The main body is disposed on a base and includes a support plate and a lower die base disposed on the support plate. A lower mounting plate and an upper mounting plate located above the lower mounting plate are disposed on the lower die base. A clamping plate is disposed between the lower mounting plate and the upper mounting plate. The clamping device includes two cylinders and push plates respectively connected to the output ends of the two cylinders. The two cylinders are fixed on the worktable. The two push plates are respectively in contact with the two lower die bases and are distributed at both ends of the lower die bases. The two push plates can clamp the two lower die bases to prevent vibration of the lower die bases and their supporting plate and lower mounting plate. Therefore, the existence of the clamping device ensures the stability of the main body after mold closing and avoids product deformation or irregular edges caused by vibration and slight shaking after molding, thereby improving the yield rate and making it suitable for widespread use.

[0016] In this invention, multiple sealing caps are fixed to the lower end face of the clamping plate. Each sealing cap has a connecting groove at both ends. The multiple sealing caps are located on multiple processing and forming stations. Multiple adapter blocks are fixed inside the lower mold base. A mold cavity is formed between the support plate, the sealing caps, and the adapter blocks. The multiple adapter blocks are respectively set below the multiple sealing caps, and each adapter block has a protrusion. The protrusion matches two connecting grooves, so that the adapter block limits the sealing cap. After the two are combined, they remain relatively stationary, so that the size of the space inside the mold cavity does not change. Therefore, the quality of the product after molding is guaranteed, and the probability of burrs is reduced. Therefore, it is highly practical. Attached Figure Description

[0027] Please see Figure 1This utility model provides an embodiment of a mold base, which includes a base body 1 and a stamping die with the above-mentioned mold base. The stamping die includes a main body 2 and a clamping device 4 and multiple sets of guiding devices 3 disposed on the main body 2. The multiple sets of guiding devices 3 are evenly disposed on the main body 2 and are all fixed on the base body 1. The multiple sets of guiding devices 3 operate together to guide the movement of the main body 2. In this embodiment, the guiding device 3 is a ball bearing sliding guide post and guide sleeve with a seat, and its model is MYKP50-220. There are four sets of guiding devices 3, which are distributed at the four corners of the main body 2, so that the four corners of the main body 2 remain stable during movement. Specifically, the four sets of guiding devices 3 are all fixed on the upper surface of the worktable 13, so that the four sets of guiding devices 3 remain stable.

[0028] Please see Figure 2 The base 1 includes a base plate 11 and multiple vertical beams 12 fixed to the upper surface of the base plate 11. A work platform 13 is fixed to the upper surface of the multiple vertical beams 12. Multiple processing and forming stations are set on the work platform 13, which can perform stamping and forming of multiple products at one time, thereby improving processing efficiency.

[0029] Please see Figures 3 to 4 The main body 2 is set on the base 1, and the main body 2 includes a support plate 21 and a lower mold base 22 set on the support plate 21. The support plate 21 is fixed to the upper end face of the workstation 13. A lower mounting plate 23 and an upper mounting plate 24 located above the lower mounting plate 23 are provided on the lower mold base 22. A clamping plate 25 is provided between the lower mounting plate 23 and the upper mounting plate 24. The installation method and working method of the support plate 21, lower mold base 22, lower mounting plate 23, upper mounting plate 24 and clamping plate 25 are existing technologies and will not be described in detail here. A top plate 26 is fixed on the top of the clamping plate 25.

[0030] Please see Figure 5 Multiple sealing caps 27 are fixed on the lower end face of the clamping plate 25. Each sealing cap 27 has a connecting groove 271 at both ends. The multiple sealing caps 27 are located on multiple processing and forming stations. Multiple adapter blocks 28 are fixed inside the lower mold base 22. The multiple adapter blocks 28 are respectively set below the multiple sealing caps 27, and each adapter block 28 has a protrusion 281. The protrusion 281 is adapted to the two connecting grooves 271, so that the adapter block 28 limits the sealing cap 27. After the two are combined, they remain relatively stationary, thus ensuring the quality of the formed product and reducing the probability of burrs. A mold cavity 29 is formed between the support plate 21, the sealing caps 27 and the adapter blocks 28. There are multiple mold cavities 29, which are distributed at the bottom of the multiple sealing caps 27. The bottom of the adapter blocks 28 is fixed on the support plate 21.

[0031] Please see Figure 6The clamping device 4 includes two cylinders 41 and push plates 42 connected to the output ends of the two cylinders 41 respectively. The two cylinders 41 are fixed on the worktable 13 and are symmetrical about the two ends of the main body 2. The two push plates 42 are respectively in contact with the two lower mold bases 22 and are distributed at both ends of the lower mold bases 22. Therefore, the two push plates 42 can clamp the two lower mold bases 22 to prevent the lower mold bases 22 and their supporting plates 21 and lower mounting plates 23 from vibrating. Therefore, the existence of the clamping device 4 ensures the stability of the main body 2 after mold closing and avoids product deformation or irregular edges caused by vibration and slight shaking after molding.

[0032] Working principle: Please refer to the following again. Figures 1 to 6 In the operation of this utility model, multiple workpieces to be processed are respectively set in multiple mold cavities 29. Two cylinders 41 drive two push plates 42 to clamp the lower mold base 22. During stamping, the clamping plate 25 drives multiple sealing covers 27 to be stamped downwards simultaneously. Finally, each sealing cover 27 is limited by the adapter block 28 below it, so that the sealing cover 27 completes the stamping of multiple workpieces and forms them in the mold cavity 29. Then, the clamping plate 25 drives the sealing cover 27 to separate from the formed product, and then the product can be taken out.
