[0022] The technical solutions of the present application will be described clearly and completely below in connection with the embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative effort are within the scope of the present application.

[0023] Referring to Figures 1-4 , the present application provides a technical solution:

[0024] Embodiment 1:

[0025] As Figures 1-3 shown, a milling cutter for thread forming part of embryo ring integrated forming die, including handle 1 and the cutter head 2 of the first end of handle 1, the cutter head 2 is away from the one end of handle 1 and is equipped with the cutting edge 3 for processing embryo ring integrated forming die thread forming part, the cutting edge 3 and cutter head 2 form T-shaped structure;

[0026] The blade diameter of the cutting edge 3 is ( Figure 3 D1) 11.5 mm.

[0027] The diameter of the cutter head 2 is ( Figure 3 D2) 8 mm.

[0028] The length of the cutter head 2 is ( Figure 3 L2) 22.21 mm, the length of the cutting edge 3 is ( Figure 3 L3) 1.3 mm, the angle of the cutting edge 3 is ( Figure 3 α) 19 ° (this cutter processes 2925 die thread forming using cutter).

[0029] The total length of the handle 1, the cutter head 2 and the cutting edge 3 is ( Figure 3 L1) 75 mm.

[0030] The cutting edge 3 includes (arranged in order from the handle 1 to the cutter head 2 direction) first forming surface 4 and second forming surface 5, the first forming surface 4 and the second forming surface 5 are both circular arc surface structure, the third forming surface 6 is inclined surface structure, the radius of the first forming surface 4 is 0.5 mm, and the radius of the second forming surface 5 is 0.2 mm.

[0031] The cutting edge 3 is provided with a metal coating. Wherein, the metal coating is ALTIN+TISI composite coating: the intermediate layer is high red hardness, and the network structure of the outer layer silicon element has better stability.

[0032] Working principle: When machining the internal threads of the mold, (1) rough machining is performed, and the threads are initially formed by milling with a cutting tool. The milling process leaves a machining allowance of 10-12 mils. (2) Finish machining is performed, and the remaining 10-12 mils of machining allowance is removed by electrical discharge machining, so that the mold thread forming part is fully formed.

[0033] This invention enables rapid rough machining of the threaded part of a mold by setting a special tool, which greatly improves the processing efficiency of the mold, shortens the processing time, and extends the service life of the tool. At the same time, by combining the remaining part with electrical discharge machining, the threaded part is fully formed, thus improving the quality of the mold.

[0034] Example 2:

[0035] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the length of the cutter head 2 is ( Figure 4 The length of the blade 3 (L2) is 28.70 mm. Figure 4 The L4 value is 1.79mm, and the blade angle ( ) is... Figure 4 (β) is 35°.

[0036] The cutting tool in this embodiment is used for machining 3025 die thread forming with a different pitch than that in Embodiment 1.

[0037] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
