Description

Technical Field

[0001] This utility model relates to the field of cylinder plate processing technology, and in particular to an integral cylinder plate forming and pressing mold. Background Technology

[0002] The cylinder is a key combing element in a combing machine. Its main function is to comb the cotton fiber bundles clamped by the clamping plates, improve the fiber separation, straightness, and parallelism, eliminate the forward hooks of the cotton fibers, thereby improving the luster of the yarn and the spinnability of the next process. It also combs away all the short fibers that are not clamped, improving the uniformity of the fibers and increasing the yarn strength. Furthermore, it combs off the cotton knots, impurities, and defects attached to the fibers, thus improving the quality of the yarn from multiple aspects.

[0003] A search revealed that the document with publication number "CN217298124U" states that "this utility model discloses a split-type cylinder, including a rotating shaft, a base that cooperates with the rotating shaft, and a rack combing area set on the base. The base has sealing plates on both sides, and the sealing plates are connected to the base by keyway engagement." In use, the sealing plates are installed on the base by keyway engagement, enabling quick installation of the equipment. At the same time, the installation methods are more diverse and can adapt to more actual working conditions.

[0004] However, existing cylinders lack an effective ejection mechanism during compression molding, which causes the cylinder disc to easily get stuck in the mold after molding. This requires manual or other auxiliary tools for demolding, which is not only inefficient but may also damage the cylinder disc.

[0005] Therefore, we provide an integral cylinder disc forming and pressing mold to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 As shown, this utility model provides a technical solution: an integral cylinder disc forming and pressing mold, including a mold base frame 1, a mold top frame 2 is provided on the upper side of the mold base frame 1, a pressing and unloading assembly 3 is installed on the inner side of the mold base frame 1, the pressing and unloading assembly 3 includes positioning posts 301 installed at the four corners of the mold base frame 1, a pressing upper mold 303 is installed at the bottom end of the mold top frame 2, a pressing lower mold 304 is provided inside the mold base frame 1, a forming hole 305 is opened on the surface of the pressing lower mold 304, bottom grooves 306 are opened on the left and right sides of the surface of the pressing lower mold 304, and a demolding top plate 307 is installed on the inner side of the bottom groove 306.

[0033] Furthermore, positioning connection holes 302 are provided at the four corners of the mold top frame 2. The positioning pin 301 is slidably connected to the positioning connection hole 302. Through the direct insertion of the positioning pin 301 and the positioning connection hole 302, the mold top frame 2 can move vertically smoothly on the mold base frame 1, ensuring accurate alignment between the upper pressing mold 303 and the lower pressing mold 304, thereby improving the quality and efficiency of pressing and forming.

[0034] Furthermore, a pressure strip is provided at the bottom of the upper pressing die 303. The forming hole 305 and the pressure strip under the upper pressing die 303 are on the same vertical horizontal line. The pressure strip on the upper pressing die 303 presses the cylinder disc material so that it can be accurately filled into the forming hole 305, ensuring that the formed cylinder disc has consistent and high-precision dimensions.

[0035] Furthermore, four sets of demolding top plates 307 are provided. The demolding top plates 307 are tightly fitted with the bottom groove 306. The surface of the demolding top plates 307 is flush with the surface of the pressing lower mold 304. After pressing is completed, the hydraulic push rod 308 pushes the demolding top plates 307 to rise. Since the surface of the demolding top plates 307 is flush with and tightly fitted with the surface of the pressing lower mold 304, the rise of the demolding top plates 307 can push the formed cylinder plate out of the forming hole 305, thereby achieving rapid demolding and avoiding the problem of the cylinder plate being stuck in the mold and difficult to remove.

[0036] Furthermore, a hydraulic push rod 308 is installed at the bottom of the demolding top plate 307. The hydraulic push rod 308 is fixedly connected to the mold base 1. The demolding top plate 307 forms a lifting structure with the lower pressing mold 304 through the hydraulic push rod 308. The hydraulic push rod 308 drives the demolding top plate 307 to rise, so that the demolding top plate 307 can easily lift the formed cylinder. Even if there is a certain adhesion between the cylinder and the forming hole 305, it can still be demolded smoothly, ensuring the convenience of cylinder demolding.

[0037] Furthermore, the forming holes 305 are evenly distributed on the surface of the pressing mold 304, and each forming hole 305 is provided with an air inlet 309. During the pressing process, gas is delivered into the forming holes 305 through the air inlet 309 to increase the air pressure in the mold, which helps the raw materials to be evenly distributed and tightly adhered during the pressing process, thereby improving the molding quality and efficiency.

[0038] Furthermore, connecting air pipes 310 are installed at both ends of the mold base 1. An adapter pipe 311 is installed at the rear end of the connecting air pipe 310. An air pump connecting pipe 312 is installed at the rear end of the adapter pipe 311. The air pump connecting pipe 312 is connected to an external air pump. The air inlet 309 is connected to the connecting air pipe 310. The external air pump delivers gas to the air inlet 309 through the air pump connecting pipe 312 and the connecting air pipe 310, ensuring that the gas can enter each forming hole 305 evenly and efficiently, providing stable gas support for the forming of the cylinder. At the same time, after pressing, the cylinder can be lifted out of the forming hole 305 by air pressure, increasing the efficiency and effect of cylinder demolding.

[0039] Working principle: The device is moved to the working position, and then the mold top frame 2 is installed on the mold base frame 1 through the positioning connection hole 302 and the positioning pin 301, ensuring accurate alignment between the upper pressing mold 303 and the lower pressing mold 304. Next, the raw material is placed on the lower pressing mold 304, and the cylinder is pressed and shaped by the cooperation of the upper pressing mold 303 and the lower pressing mold 304. During the pressing process, the external air pump is started, and air is supplied to the air inlet 309 through the air pump connection pipe 312 and the air pipe 310, increasing the air pressure inside the mold, which helps to achieve uniform distribution and tight adhesion of the raw material. After pressing, the mold top support 2 is raised, and then the hydraulic push rod 308 is activated. The hydraulic push rod 308 pushes the demolding top plate 307 to rise. Since the demolding top plate 307 is flush with and tightly fitted to the surface of the lower pressing mold 304, the rise of the demolding top plate 307 can smoothly eject the formed cylinder from the lower pressing mold 304. At the same time, the air pressure pushes the cylinder from the forming hole 305, increasing the efficiency and effect of cylinder demolding and achieving rapid demolding. Finally, the demolded cylinder is taken out for the next step of processing. This completes the use process of an integral cylinder forming and pressing mold.

[0040] 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.
