The surface of the pulling plate 35 is slidably connected to the inside of the connecting housing 102. A transmission block 36 is fixedly connected to the top of the pulling plate 35. The top of the transmission block 36 passes through the connecting housing 102 and extends to the top of the connecting housing 102 where a clamping plate 37 is fixedly connected.

[0028] refer to Figure 4 The cutting machine 2 includes a cylinder 21, which is fixedly connected to both sides of the top of the machine frame 104.

Positioning blocks 23 are fixedly connected to both sides of the bottom of the lifting plate 22, and an electric cutting disc 24 is fixedly installed inside the positioning block 23.

[0029] As a technical optimization of this utility model, a cutting machine 2 is set up, in which a cylinder 21 is fixedly connected to both sides of the top of the machine frame 104. Its output end passes through the machine frame 104 and extends to the bottom of the machine frame 104, where a lifting plate 22 is fixedly connected. Positioning blocks 23 are fixedly connected to both sides of the bottom of the lifting plate 22. An electric cutting disc 24 is fixedly installed inside the positioning block 23. This allows the cutting tool to be precisely adjusted in height and telescopically controlled according to the workpiece requirements. Compared with the traditional cutting device, which lacks precise control over the cutting depth and tool position, this structure can flexibly adapt to the cutting needs of molds of different specifications and shapes. During high-speed cutting, the tool position and cutting depth can be adjusted in real time according to the material characteristics and cutting requirements, effectively suppressing vibration and offset caused by cutting force, ensuring the stability of the cutting process, thereby improving cutting accuracy and quality, reducing scrap rate, and meeting the high precision requirements of molds for manufacturing high-end vehicle parts.

[0030] refer to Figure 2 The top of the connecting housing 102 is provided with a positioning hole 4, and the interior of the positioning hole 4 is slidably connected to the surface of the transmission block 36.

[0031] As a technical optimization of this utility model, by setting a positioning hole 4, which is slidably connected to the surface of the transmission block 36, a precise positioning guide is provided during the movement of the clamping plate 37 driven by the transmission block 36. This allows the clamping plate 37 to move smoothly along a predetermined trajectory when clamping the workpiece, avoiding shaking or deviation, and further enhancing the accuracy and stability of workpiece fixing.

[0034] refer to Figure 1 The clamping plate 37 is equipped with a clamping cylinder 6 inside, and the top and bottom of the clamping cylinder 6 are movably connected to the inside of the clamping plate 37 through a rotating shaft.

[0035] As a technical optimization of this utility model, by setting a clamping cylinder 6, the top and bottom of which are movably connected to the inside of the clamping plate 37 through a rotating shaft, when the clamping plate 37 clamps the workpiece, the clamping cylinder 6 can adaptively adjust according to the surface shape of the workpiece, increase the contact area with the workpiece, and make the clamping force distribution more uniform.

[0036] refer to Figure 2 and Figure 4 Cutting grooves 7 are provided on both sides of the top of the connecting chassis 102. A reinforcing plate 8 is fixedly connected to the inner side of the positioning block 23. The top of the reinforcing plate 8 is fixedly connected to the bottom of the lifting plate 22.

[0037] As a technical optimization of this utility model, the cutting groove 7 provides space for the cutting operation of the cutting tool, avoiding interference between the tool and the machine housing. The reinforcing plate 8 on the inner side of the positioning block 23 is fixedly connected to the lifting plate 22, which enhances the strength and rigidity of the overall structure of the cutting machine 2.

[0038] The working principle and usage process of this utility model are as follows: First, check the connection of each component and the operating status of the power component to ensure normal operation. Place the workpiece to be cut into the connecting housing 102. Use the roller 103 inside the housing to reduce friction, facilitating adjustment of the workpiece to a suitable position to complete the pre-positioning. Then, activate the workpiece fixing mechanism 3. The electric telescopic rod 31 on the back of the inner wall of the frame 1 extends, pushing the moving plate 32 forward. The moving plate 32, through the connecting blocks 33 on both sides, drives one end of the pulling rod 34 forward, and the other end of the pulling rod 34 pulls the pulling plate. 35 slides inward within the connecting housing 102. The pulling plate 35 passes through the positioning hole 4 via the top transmission block 36, driving the clamping plate 37 to move closer to the workpiece. The clamping plate 37 tightly adheres to the workpiece surface through the internal clamping cylinder 6, evenly distributing the clamping force to achieve stable and precise clamping. According to the mold cutting requirements, the cutting machine 2 is started. The output ends of the cylinders 21 on both sides of the top of the machine frame 104 extend, pushing the lifting plate 22 to move downward along the sliding groove 5 on the inner wall of the machine frame 104. The lifting plate 22 drives the electric cutting disc 24 to move downward through the positioning block 23 to cut the workpiece.

[0039] In summary, this precision cutting device for high-end vehicle parts manufacturing molds, by setting up a frame 1, with the connecting housing 102 on the top of the base plate 101 cooperating with the roller 103, facilitates the movement and positioning of the workpiece within the housing. At the same time, the frame 1 provides stable support for the cutting machine 2 and the workpiece fixing mechanism 3. Furthermore, the workpiece fixing mechanism 3 enables precise clamping of the workpiece, replacing the traditional manual clamping or mechanical fixture fixing methods. This makes operation simpler and reduces manpower and time costs.
