[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 Figures 1-7 The present invention provides the following technical solution.

[0033] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a cutting tool for mold steel, comprising a cutting tool handle 1, a cutting tool head 2, a mounting hole 3, a mounting cylinder 4, a mounting plate 5, and a mounting rod 6. The cutting tool handle 1 and the cutting tool head 2 are welded together. The upper right end of the cutting tool handle 1 has a mounting hole 3. The mounting plate 5 is fitted onto the right side of the lower end of the cutting tool head 2, and the mounting rod 6 is fixedly connected to the middle of the mounting plate 5. The mounting rod 6 and the mounting cylinder 4 form a sliding structure, and the mounting rod 6 is inserted into the mounting hole 3. Figure 1 and Figure 2 As shown, during installation, first insert the cutting blade handle 1 into the lower end of the mounting cylinder 4, and then put the mounting plate 5 on the right side of the lower end of the cutting blade head 2. At the same time, the mounting plate 5 drives the mounting rod 6 through the right end of the cutting blade head 2, and the mounting rod 6 is inserted into the mounting hole 3, which facilitates the connection between the cutting blade handle 1 and the mounting cylinder 4.

[0034] Example 2: Existing die steel cutting tools are inconvenient to disassemble and replace, and their installation is not very secure. Therefore, a mounting plate 5, mounting rod 6, limiting rod 7, mounting cap 8, and mounting groove 9 are provided. The front and rear ends of the left side of the mounting plate 5 are connected to the limiting rod 7 via slots, and the mounting plate 5 has a mounting groove 9 on its left side. The limiting rod 7 is fixedly connected to the front and rear ends of the lower end of the mounting cylinder 4. The outer surface of the limiting rod 7 is threaded with the mounting cap 8, which limits the movement between the mounting plate 5 and the limiting rod 7. The mounting cap 8 engages in the mounting groove 9. Figure 2 , Figure 3 and Figure 4 As shown, the mounting plate 5 drives the mounting rod 6 to be inserted into the mounting hole 3. At the same time, the front and rear ends of the left side of the mounting plate 5 are connected to the limiting rod 7 through slots. Then, by rotating the mounting cap 8, which is threaded onto the outer surface of the limiting rod 7, the mounting cap 8 is engaged in the mounting groove 9. The mounting cap 8 limits the distance between the limiting rod 7 and the mounting plate 5, thereby facilitating the restriction between the mounting plate 5 and the limiting rod 7 and preventing the mounting rod 6 from moving out of the mounting hole 3. This improves the tightness of the cutting tool installation. The overall installation, disassembly and replacement are very convenient.

[0035] Example 3: Existing die steel cutting tools are inconvenient to operate when adjusting the cutting angle, and it is also inconvenient to lock them after adjustment. Therefore, by setting up a tool holder 10, a fixing groove 11, a positioning mechanism 12, and a limiting groove 17, a rotating structure is formed between the mounting cylinder 4 and the tool holder 10. The positioning mechanism 12 includes a spring 13 set inside the mounting cylinder 4, a fixing post 14 fixedly connected to the movable end of the spring 13, a movable block 15 rotatably installed at the lower end of the fixing post 14, and an auxiliary rod 16 fixedly connected to the side of the movable block 15. A torsion spring is set at the connection between the fixing post 14 and the movable block 15, and the fixing post 14 is telescopically connected to the middle of the mounting cylinder 4. The upper end of the fixing post 14 is engaged in the fixing groove 11, which is located in the middle of the tool holder 10. The auxiliary rod 16 is engaged in the limiting groove 17, which is located on the side of the mounting cylinder 4. Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, when the operating angle of the cutting blade needs to be adjusted, by pulling the auxiliary rod 16, the auxiliary rod 16 causes the movable block 15 to slide at the lower end of the fixed post 14. At this time, the torsion spring undergoes elastic deformation, and the auxiliary rod 16 moves out of the limiting groove 17, thereby releasing the lock between the fixed post 14 and the mounting cylinder 4. Then, by pulling the auxiliary rod 16 downward, the auxiliary rod 16 causes the fixed post 14 to slide between the mounting cylinder 4 and the mounting cylinder 4 through the movable block 15. The fixed post 14 compresses the spring 13, causing the spring 13 to undergo elastic deformation. The fixed post 14 moves downward and moves out of the fixing groove 11, thereby releasing the limit between the mounting cylinder 4 and the blade holder 10. Then, by rotating the mounting cylinder 4, the operating angle of the cutting blade is adjusted, allowing the cutting blade to... With the cutter head 2 facing the side of the workpiece to be machined, after adjustment, the auxiliary rod 16 is released directly. At this time, the spring 13 restores its elastic deformation and pushes the fixed column 14 downward, so that the upper end of the fixed column 14 is engaged in the fixed groove 11, which facilitates the limiting of the mounting cylinder 4 and the tool holder 10. When the fixed column 14 drives the movable block 15 and the auxiliary rod 16 to move upward to the position flush with the limiting groove 17, the torsion spring between the movable block 15 and the fixed column 14 restores its elastic deformation, causing the movable block 15 and the fixed column 14 to rotate, so that the movable block 15 drives the auxiliary rod 16 to engage in the limiting groove 17, which facilitates the locking between the fixed column 14 and the mounting cylinder 4, further improving the stability of the connection between the fixed column 14 and the mounting cylinder 4.

[0036] 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.
