Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, a profile forming mold with a gradually shrinking forming cavity comprises a mold body 1, wherein the mold body is provided with a forming cavity 2, the mold body is provided with a rear side 3 for entering forming materials and a front side 4 for leading out the forming materials from the forming cavity, the forming cavity is a cavity penetrating from the rear side to the front side, and the mold body is also provided with a center connecting line 5 for connecting the center of the rear side and the center of the front side; the method is characterized in that: the forming inner cavity is a structure which is gradually reduced from the rear side to the front side.
According to the arrangement of the invention, the molding material enters from the rear side 3 of the molding cavity, and under the same thrust force on the molding material, because the resistance of the rear side of the mold body to the molding material entering the mold body is small, the molding material comes out from the front side quickly, so that the production efficiency can be improved, generally speaking, the production efficiency is improved by about 5%, and the purpose of the invention is not met.
On the other hand, the quality of the formed profile surface can be improved, the profile surface is smoother, and the phenomenon of scratching is reduced.
Furthermore, the included angle alpha between the side wall of the forming cavity and the central connecting line is 5-10 degrees.
The arrangement is reasonable.
Furthermore, the front surface of the die body is provided with an extension body 6, the extension body is provided with an extension cavity 61, the rear surface of the extension cavity is smoothly connected with the forming inner cavity, and the cross sections of the extension cavity from the rear to the front are the same.
The profile surface thus formed reduces the corrugation of the wave length direction along the length direction of the profile.
The extension body and the die body are of an integrated structure.
Alternatively, the extension is attached to the die body by screws 62, which facilitates replacement of the extension.
Furthermore, an expansion groove 7 is arranged around the forming cavity behind the die body, and a graphite block 8 is arranged in the expansion groove, wherein the graphite block forms a smooth surface on one side of the forming cavity and around the forming cavity, such as the upper structure on the right side in fig. 1.
Thus, the lubricating oil has a lubricating effect on the entering molding materials, and can improve the product quality and the production efficiency.
Furthermore, an expanding groove 7 is arranged around the forming cavity behind the die body, a cutter seat 91 of a dividing cutter 9 is also arranged in the expanding groove, the dividing cutter is provided with a cutting edge 92 at the right end, and the cutting edge of the dividing cutter is arranged around the forming cavity; the inner side of the dividing knife is formed with a rightward expanding bellmouth structure 93.
Preferably, the blade part is further provided with a triangular notch structure 94, and the notch structure is arranged backwards. As shown in the lower right-hand structure of fig. 1 and fig. 2.
The cutting edge is arranged to facilitate the cutting of the raw materials entering the forming cavity, so that the production efficiency is improved.
