[0010] (III) Beneficial Effects

[0011] This invention provides a high-hardness die end mill with a replaceable integral cutter head. It has the following advantages:

[0012] (i) This high-hardness mold milling cutter with replaceable integral cutter head directly undertakes mold milling work through the cutter head body in the mounting assembly. The quick-connect assembly uses the insert block on the top of the cutter bar and the locking block on the rotating ring to achieve quick disassembly and assembly of the cutter head and cutter bar by pressing the top ring to compress the top spring and then rotating to lock them together. This toolless operation design makes the tool changing process simple and quick.

[0013] (II) This high-hardness mold end mill with a replaceable integral cutter head is connected to the bottom of the cutter shank via a fixed post inside the damping assembly. An elastic rope inside the assembly suspends a ball, which, together with injected silicone oil, forms a composite damping system. When the tool vibrates during machining, the ball swings under the action of the elastic rope, and the silicone oil dampens the movement of the ball. Both of these components together consume vibration energy. The threaded post at the bottom can be used to replace internal parts or fine-tune the structure to adapt to different machining needs. The damping assembly suppresses machining vibration, keeping the cutter head in a stable cutting state. This design not only improves the accuracy and surface quality of mold machining but also reduces tool wear and extends service life. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a high-hardness mold milling cutter with replaceable integral cutter head, including: a mounting component 1, and a quick-connect component 2, the outer wall of the quick-connect component 2 being snapped into the inner wall of the mounting component 1, and a shock-absorbing component 3 being fixedly connected to the bottom of the quick-connect component 2; the quick-connect component 2 includes a cutter bar 25, a plug block 21 being fixedly connected to the top of the cutter bar 25, a rotating ring 22 being rotatably connected to the outer wall of the top of the cutter bar 25, a locking block 23 being fixedly connected to the top of the rotating ring 22, and the locking blocks 23 being arranged in a circular array along the central axis of the rotating ring 22, a top ring 24 being slidably connected to the outer wall of the cutter bar 25, a top spring 26 being fixedly connected to the bottom of the top ring 24, and the bottom of the rotating ring 22 being pressed and fixed to the top of the top ring 24.

[0022] Mounting assembly 1 includes a cutter head body 11. The bottom of the cutter head body 11 is engaged with the outer wall of the locking block 23 via a slot 12, and the slot 12 is located in the wall of the cutter head body 11. The bottom of the cutter head body 11 is engaged with the outer wall of the insert block 21 via a slot 13, and the slot 13 is located in the wall of the cutter head body 11. The bottom of the cutter head body 11 is in contact with the top of the rotating ring 22. Pressing down on the top ring 24 compresses the top spring 26, allowing the rotating ring 22 to rotate freely. At this time, the insert block 21 at the top of the cutter bar 25 is inserted into the slot 13 at the bottom of the cutter head body 11. Then, the rotating ring 22 is rotated so that the locking block 23 is engaged in the slot 12 of the cutter head body 11. After releasing the top ring 24, the elastic force of the top spring 26 pushes the top ring 24 upward, pressing the rotating ring 22 tightly against the bottom of the cutter head body 11.

[0023] The vibration damping assembly 3 includes a fixed post 31. An elastic rope 33 is fixedly installed on the inner wall of the top of the fixed post 31 via a fixed hook 32. The top of the fixed hook 32 is fixedly connected to the inner wall of the top of the fixed post 31. A ball 34 is fixedly connected to the bottom of the elastic rope 33. A threaded post 35 is threadedly connected to the inner wall of the bottom of the fixed post 31. The outer wall of the fixed hook 32 is fixedly installed to the outer wall of the elastic rope 33. The top of the fixed post 31 is fixedly connected to the bottom of the tool holder 25. The top of the fixed post 31 is fixedly connected to the end of the top spring 26 away from the top ring 24. Silicone oil is injected into the cavity inside the fixed post 31. The ball 34 inside the fixed post 31 will swing under the action of the elastic rope 33. At the same time, the silicone oil injected into the fixed post 31 will dampen the movement of the ball 34 and consume vibration energy. The elasticity of the elastic rope 33 on the fixed hook 32 can also absorb some vibration energy, thereby reducing the vibration amplitude of the tool.

[0024] This mold milling cutter mainly consists of a mounting component 1, a quick-connect component 2, and a shock-absorbing component 3. The core of the mounting component 1 is the cutter head body 11, which is responsible for directly milling the mold. The top of the cutter shank 25 of the quick-connect component 2 is provided with a plug 21. The rotating ring 22 on the outer wall of the cutter shank 25 cooperates with the top ring 24. The locking blocks 23 on the top of the rotating ring 22 are distributed in a ring array. The top of the fixing post 31 of the shock-absorbing component 3 is connected to the cutter shank 25. It contains an elastic rope 33 and a ball 34, and the bottom is a threaded post 35.

[0025] The quick-connect assembly 2 is the key component for enabling rapid tool head replacement. When a tool head needs to be installed, press down on the top ring 24 to compress the top spring 26, allowing the rotating ring 22 to rotate freely. At this time, insert the insert block 21 at the top of the tool shank 25 into the slot 13 at the bottom of the tool head body 11. Then, rotate the rotating ring 22 to make the locking block 23 engage in the locking groove 12 of the tool head body 11. After releasing the top ring 24, the elastic force of the top spring 26 will push the top ring 24 upward, pressing the rotating ring 22 tightly against the bottom of the tool head body 11, thus completing the tool head installation and ensuring a firm connection between the tool head and the tool shank 25. When disassembling the tool head, simply repeat the above pressing and rotating actions. The entire process is simple and quick, shortening the tool replacement time.

[0026] During the milling of high-hardness molds, the cutting tool is prone to vibration, which not only affects the machining accuracy but also reduces the tool life. The vibration damping component 3 can solve this problem. When the cutting tool vibrates during machining, the ball 34 inside the fixed column 31 will swing under the action of the elastic rope 33. At the same time, the silicone oil injected into the fixed column 31 will dampen the movement of the ball 34 and consume the vibration energy. The elasticity of the elastic rope 33 on the fixed hook 32 can also absorb some of the vibration energy, thereby reducing the vibration amplitude of the cutting tool. The threaded column 35 can replace the parts inside the fixed column 31.

[0027] In actual processing, the mounting component 1, quick-connect component 2, and vibration damping component 3 work together in coordination. When the cutter head body 11 rotates at high speed to mill the mold, the quick-connect component 2 ensures that the cutter head will not loosen under the action of cutting force through the tight fit between the locking block 23 and the locking groove 12. Meanwhile, the vibration damping component 3 continuously suppresses the vibration generated during processing, enabling the tool to maintain a stable cutting state. This coordinated working method not only improves the accuracy and surface quality of mold processing, but also reduces tool wear and extends tool life.
