The cutter includes a chamfering cutter body with at least two cutting edges. A working chamber is formed in the cutter body, and a lens is provided on the side wall of the working chamber. A piston is also provided in the working chamber, with a light-transmitting hole and a mounting hole. A light source is provided at the mounting hole. A photoelectric switch is also provided on the side wall of the working chamber, electrically connected to an AC power source. An mounting chamber is also formed in the chamfering cutter body, containing an arc-shaped protrusion. A first spring connects the arc-shaped protrusion to the working chamber. The arc-shaped protrusion has a permanent magnet and an arc-shaped cutting edge. An electromagnetic block is also provided on the upper side of the arc-shaped protrusion, and an excitation coil is fitted onto the electromagnetic block. This solution solves the problem of manual deburring required after chamfering in traditional processing methods, effectively improving the processing efficiency of molding dies and reducing the labor intensity of workers.

[0004] The existing technology has the following technical problems: the existing chamfering cutter used for processing plastic bottle molding molds is not convenient for detecting the overall temperature, the deformation at the connection between the cutter shank and the cutter bar, or the overall vibration frequency; therefore, we propose a chamfering cutter for processing plastic bottle molding molds to solve the problems mentioned above.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] To address the technical problems of existing chamfering cutters used in plastic bottle molding processes, which make it difficult to detect overall temperature, deformation at the connection between the cutter shank and the cutter bar, and overall vibration frequency, this embodiment discloses the following technical solution: Please see Figure 1 - Figure 6 A chamfering cutter for processing plastic bottle molding dies includes a cutter head 1, a cutter shank 2, a cutter bar 3, a connecting structure 4, a locking block 401, a locking groove 402, a square block 403, a temperature detection structure 5, a mounting half-ring 501, a temperature sensor 502, a connecting plate 503, an auxiliary ring 504, a rubber pad 505, a strain gauge 6, a vibration measuring structure 7, a circuit board 701, a miniature piezoelectric accelerometer 702, and an annular groove 8.

[0021] like Figure 1 - Figure 4 and Figure 6 As shown, the temperature detection structure 5 includes a mounting half-ring 501, a temperature sensor 502, a connecting plate 503, an auxiliary ring 504, and a rubber pad 505. The arc surface of the cutter bar 3 is provided with an annular groove 8, and multiple temperature sensors 502 are arranged at equal angles in the annular groove 8, which facilitates the detection of the temperature of the cutter bar 3. When the cutter head 1 is in use, the temperature will be transferred to the cutter bar 3, which facilitates the detection of the overall temperature. Multiple temperature sensors 502 are fixedly mounted at equal angles on the inner ring wall of the mounting half-ring 501. A connecting plate 503 is fixedly mounted on the outer side of the mounting half-ring 501. The two mounting half-rings 501 are fixedly connected by the connecting plate 503 and bolts, thereby fixing the temperature sensor 502 in the ring groove 8. This makes it easy to disassemble the temperature sensor 502, that is, the temperature sensor 502 can be disassembled by removing the bolts, thus facilitating the maintenance of the temperature sensor 502. An auxiliary ring 504 is fixedly installed on the outside of the tool holder 3. A rubber pad 505 is fixedly installed on one end of the auxiliary ring 504 near the mounting half ring 501. Rubber pads 505 are provided at both the top and bottom of the mounting half ring 501. The auxiliary ring 504 protects the rubber pads 505. The rubber pads 505 support and buffer the mounting half ring 501 to prevent the temperature sensor 502 from shaking due to vibration when using the chamfering tool, thus affecting the detection effect. like Figure 5As shown, a strain gauge 6 is fixedly installed inside the wall of the slot 402. The strain gauge 6 can detect the deformation of the slot wall of the slot 402 and the connection between the tool holder 2 and the tool rod 3, so as to detect the looseness at the connection in time and perform maintenance in time. like Figure 3 As shown, the vibration measurement structure 7 includes a circuit board 701 and a miniature piezoelectric accelerometer 702. The circuit board 701 is fixedly installed inside the tool holder 3. The miniature piezoelectric accelerometer 702 is fixedly installed on the circuit board 701. Vibration will be transmitted from the tool head 1 to the tool holder 3. The miniature piezoelectric accelerometer 702 can detect the frequency of the overall vibration, that is, convert the vibration frequency into a signal. The circuit board 701 converts the signal into data. The detected temperature, deformation, and vibration data are all wirelessly transmitted to the controller (not shown) for staff to view, identify anomalies promptly, and take timely action. like Figure 1 - Figure 3 and Figure 5 As shown, the connecting structure 4 includes a locking block 401, a slot 402, and a square block 403. The top of the cutter head 1 is fixedly connected to the handle 2. The locking block 401 is fixedly installed at an equal angle on the outside of the handle 2. The slot 402 is opened at an equal angle inside the cutter bar 3. The locking block 401 is engaged and connected in the slot 402. This design enables the handle 2 and the cutter bar 3 to rotate synchronously, avoiding the phenomenon of stripping. Bolts are used to fix the handle 2 and the tool bar 3. A square block 403 is fixedly installed on the outside of the tool bar 3 to increase the contact area between the bolt nut and the tool bar 3 and improve the fastening force. The two bolts are perpendicular to each other, which further improves the connection tightness.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
