Description

Technical Field

[0001] The utility model relates to the technical field of four-edge milling cutters, and particularly relates to a four-edge milling cutter for processing a special die holder. Background Art

[0002] A four-edge milling cutter is a metal cutting tool with four cutting edges, mainly used for milling operations. It can perform various machining tasks such as face milling, contour milling, and groove machining on various materials.

[0003] The above-mentioned four-edge milling cutter often has the following defects: after the four-edge milling cutter finishes machining the mold, there are often a small amount of debris residues on the outer surface or the inner surface of the side groove of the four-edge milling cutter. If the debris residues are not cleaned, during the next cutting or grinding of the mold, the debris residues will cause the surface of the cutter body to be uneven, thereby reducing the grinding accuracy and affecting the quality of the finished product. Therefore, there is a particular need for a four-edge milling cutter that can automatically clean the surface of the cutter body after cutting or grinding. Summary of the Utility Model

[0035] The exemplary embodiments of the present utility model will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided so that the present utility model can be more thoroughly understood and the scope of the present utility model can be completely conveyed to those skilled in the art.

[0036] As Figures 1 to 4 shown, an embodiment of the present utility model provides a special mold for processing a four-edge milling cutter, including:

[0037] Knife handle 1;

[0038] Knife body 2, and the knife body 2 is clamped and installed inside the knife handle 1;

[0039] Cleaning mechanism 3, which is arranged on one end surface of the knife handle 1 and is used for cleaning the outer surface of the knife body 2;

[0040] Clamping mechanism 4, which is arranged inside the knife handle 1 and is used for the quick installation and disassembly between the knife handle 1 and the knife body 2.

[0041] When processing the mold base, first install the tool body 2 quickly inside the tool holder 1 through the clamping mechanism 4. When the tool body 2 processes the mold base, there will be a small amount of debris on the tool body 2, and the cleaning mechanism 3 can clean the tool body 2.

[0042] As Figure 2 As shown, the cleaning mechanism 3 includes a plastic strip 305. A first cavity 301 is opened on the surface of one end of the tool holder 1. A first spring 302 is welded to the inner wall of the first cavity 301. One end of the first spring 302 is welded to a long rod 303. The first spring 302 is in a stretched state inside the first cavity 301, and the long rod 303 can slide inside the first cavity 30.

[0043] As Figure 2 As shown, a hollow disc 304 is fixedly installed at one end of the long rod 303. The plastic strip 305 is fixedly installed on the inner wall of the hollow disc 304. The plastic strip 305 on the hollow disc 304 can clean the tool body 2.

[0044] As Figure 2 As shown, a dust collection cover 306 is rotatably connected to the lower surface of the hollow disc 304. The dust collection cover 306 can prevent debris from spreading everywhere and concentrate the debris.

[0045] As Figure 2 As shown, it is characterized in that there are four first cavities 301, four first springs 302 and four long rods 303 respectively. The four first springs 302 are in a stretched state in the four first cavities 301 respectively, and the four long rods 303 are slidably connected in the four first cavities 301 respectively. The stretching and contraction of the first spring 302 can make the long rod 303 slide in the first cavity 301.

[0046] In the embodiment of the present utility model, first, when the tool body 2 cuts the mold, the tool body 2 drills holes in the mold first. As the depth of the hole increases, the dust collection cover 306 presses on the mold to prevent debris from splashing. Due to the increase of the holes, the long rod 303 will compress the first spring 302 inward. When the cutting is completed, the tool body 2 is taken out. At this time, the first spring 302 rebounds, and the plastic strip 305 on the hollow disc 304 can clean the debris on the tool body 2.

[0047] As Figure 3 As shown, the clamping mechanism 4 includes a circular clamping block 402. An installation cavity 401 is opened at one end of the tool holder 1. A second cavity 403 is opened on the inner wall of the installation cavity 401. A second spring 404 is welded to the second cavity 403. The circular clamping block 402 is fixedly installed at one end of the second spring 404. The tool holder 1 is installed in the installation cavity 401, and the cooperation between the circular clamping block 402 and the second spring 404 plays a clamping role.

[0048] AsFigure 3 and Figure 4 As shown in Figure 4 , a circular clamping groove 405 is formed on the outer surface of the tool body 2, a guiding groove 407 is formed on the outer surface of the tool body 2, and a limiting block 408 is welded on the outer surface of the tool body 2. The guiding groove 407 makes it easier to snap the circular clamping block 402 into the circular clamping groove 405, and the limiting block 408 plays a role in limiting.

[0049] As Figure 3 shown in Figure 3 , a magnet 406 is installed on the inner wall of the installation cavity 401, and a limiting groove 409 is formed on the inner wall of the installation cavity 401. The magnet 406 sucks the tool body 2 for convenient installation. The cooperation between the limiting block 408 and the limiting groove 409 makes the installation more convenient.

[0050] In the embodiment of the present utility model, the limiting block 408 on the tool body 2 is aligned with the limiting groove 409 in the installation cavity 401, and then the tool body 2 is pushed. The circular clamping block 402 enters the circular clamping groove 405 through the guiding groove 407, and the rebound of the second spring 404 firmly snaps the circular clamping block 402 into the circular clamping groove 405. The adsorption of the magnet 406 on the tool body 2 makes the installation more convenient.

[0051] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
