Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a rolling mold. Background Technology
[0002] A rolling die is a tool or device used to roll flat or sheet materials into a circular or cylindrical shape. Typically, a rolling die consists of several parts, including an upper die, a lower die, and a die support structure. When using a rolling die, the flat or sheet material to be processed is placed between the upper and lower dies, and then the upper and lower dies are pressed together by mechanical or hydraulic pressure, causing the flat or sheet material to gradually roll into the desired shape along the arc or circular trajectory of the die.
[0003] Chinese utility model patent CN212121292U discloses a stamping and rolling die, including an upper die and a lower die; the upper die is provided with a first stamping head and a second stamping head; the lower surface of the first stamping head has an upwardly recessed shape, and the second stamping head is provided with a cylindrical stamping model; the lower die is provided with a first groove corresponding to the first stamping head and a second groove corresponding to the cylindrical stamping model; the bottom surface of the first groove is an arc shape adapted to the lower surface of the first stamping head; the shape of the second groove is adapted to the outer contour shape of the cylindrical stamping model; the efficiency of the above solution in achieving rolling is higher than that of the first stamping head. The process is relatively simple. The first step involves cutting the roll material into a first sheet using a cutting die. Then, the first stamping head and the first groove work together to initially stamp the first sheet, causing a concave shape in the middle to form a certain arc, thus obtaining the second sheet. The second step involves placing the initially stamped second sheet on top of the second groove, and then pressing the second sheet into the second groove using a cylindrical stamping die. The second sheet bends along the outer surface of the cylindrical stamping die, and the two ends of the second sheet are rolled up to make the second sheet round. This process is quite cumbersome, and the roll material cannot be cut and rolled in one go.
[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

Example
[0021] like Figure 1-5 As shown, this application discloses a rolling die, comprising an upper die 10 and a lower die 20. The upper mold 10 includes an upper mold base 11, an upper clamping plate 12, and an upper template 13 arranged sequentially from top to bottom. An upper mold forming insert 111 and an upper mold cutting insert 112 are arranged side by side on the upper mold base 11. The lower mold 20 includes a lower mold base 21, a lower pad 22 disposed on the lower mold base 21, a lower ejector plate 23 disposed on the lower pad 22, and a first lower template 24 and a second lower template 25 disposed opposite to the lower ejector plate 23. A lower mold forming insert 26 corresponding to the upper mold forming insert 111 is disposed between the first lower template 24 and the second lower template 25. A mold core 27 fixed on the lower ejector plate 23 is disposed between the upper mold forming insert 111 and the lower mold forming insert 26. The product is cut by the upper mold cutting insert, and the upper mold forming insert, mold core and lower mold forming insert cooperate to roll the product into a circle, thereby realizing one-time cutting and rolling of the product, which not only improves production efficiency, but also reduces mold cost.
[0022] In this process, the product is first fed onto the first lower die plate. The upper die moves downward and the upper die shearing insert cuts the product. At the same time, the upper die forming insert, the lower die forming insert, and the die core set between the upper die forming insert and the lower die forming insert work together to roll the product into a circle. The upper die moves upward and the product falls off, completing one stamping process.
[0023] Specifically, the upper mold base 11 is provided with two first screw plugs 113. Each first screw plug 113 is connected to an ejector pin 115 through a first spring 114. When the upper mold moves downward, the ejector pin stops against the product to prevent the product from moving laterally. At the same time, the first spring acts as a buffer to prevent damage to the surface of the product.
[0024] Specifically, the upper mold base 11 is provided with an upper mold inserter 116, and the lower ejector plate 23 is provided with a side push mechanism for ejection that cooperates with the upper mold inserter 116 on one side relative to the first lower template 24 and the second lower template 25. The side push mechanism includes a side push block 231, a side push clamping plate 232, two second springs 234, two push rods 235, and a side ejection plate 236. The side push block 231 is located on one side of the first lower template 24 and the second lower template 25 relative to the lower ejector plate 23, and an active space is formed between the side push block 231 and the lower ejector plate 23. The side push clamping plate 232 can reciprocate linearly within the active space. The side push clamping plate 232 cooperates with the upper mold inserter 116. Two second screw plugs 233 are installed on the side push stop 231. Each second screw plug 233 is connected to a push rod 235 through a second spring 234. The push rod 235 passes through the side push clamping plate 232 and the lower ejector plate 23 in sequence and is connected to the side push ejector plate 236. Through the above structural design, the upper mold moves downward, the upper mold inserter drives the side push clamping plate away from the lower ejector plate, the second spring is compressed, and at the same time, the side push ejector plate moves away from the product rolling station. When the product is rolled and formed, the upper mold moves upward, the side push clamping plate is reset under the action of the second spring, and at the same time, the side push support plate pushes the product on the product rolling station out, causing the product to fall off.
[0025] Specifically, the side push stripper plate 236 is U-shaped, and the two arms of the side push stripper plate 236 are respectively connected to the two push rods 235. A clearance space is formed between the two arms to avoid the mold core 27, so that the side push stripper plate can match the shape of the rolled product, thereby enabling the product to be pushed out better after the product is rolled.
[0026] Specifically, two lower template guide plates 241 are arranged opposite to each other on the first lower template 24, and an active space is formed between the two lower template guide plates 241 for the ejector pin to pass through.
[0027] Specifically, a number of springs 28 are provided between the lower stripper plate 23 and the lower pad plate 22. When stamping is performed, these springs can absorb impact energy, reduce the direct impact force on the mold assembly, and extend the service life of the mold.
[0028] Specifically, a lower pad 211 is provided below the lower mold base 21. The lower pad 211 is connected to a push rod 213 through a third spring 212. The push rod 213 passes through the lower mold base 21 and the lower pad 22 in sequence and is connected to the lower mold forming insert 26. Through the above structural design, the third spring plays a buffering role, reducing the direct impact force on the mold components and extending the service life of the mold. After the rolling is completed, the elastic force provided by the third spring helps to push the product out of the lower mold forming insert, which facilitates the product unloading.
[0029] Specifically, two lower feet 29 are arranged side by side below the lower mold base 21 to support the lower mold part and ensure the stability and accuracy of the mold during operation.
[0030] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, high efficiency, and low cost.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
