[0002] Thermoplastic is a kind of plastic that has plasticity at a certain temperature, solidifies after cooling and can repeat this process. Its molecular structure feature is a linear macromolecular compound. Generally, it does not undergo cross-linking between linear molecules when heated. When processing thermoplastic into a primary mold embryo, it needs to be fixed by a fixing structure and then cut by a cutting machine.

[0003] According to the "Cutting Machine for Fixing Thermoplastic Processing" with the Chinese patent publication number CN220007910U, it mainly describes that by providing a hydraulic pile, it is beneficial to ensure the main transmission mechanism of the main cutting main frame; by setting a fixed top frame, it ensures the upper frame body of the main cutting main frame and at the same time ensures the connection with the corresponding structure; by setting an auxiliary block and an auxiliary telescopic rod, it ensures the auxiliary frames on both sides of the main cutting main frame to ensure the fixity of the main cutting main frame; by setting a pile telescopic rod, it ensures the connection and transmission inside the main cutting main frame; by setting a fixed groove body, it ensures the connection of the corresponding structure; by setting a connecting vertical beam and a fixed auxiliary rod, it ensures the fixation of the fixed groove body and at the same time ensures the synchronous progress of the structure during use; by setting a protection baffle, it protects the cutting tool body to avoid direct contact with sharp objects during use. During this process, the sizes of thermoplastic mold embryos are different, and the surfaces of the mold embryos are not necessarily flat during the processing, so the stability of thermoplastic during cutting by the cutting machine is not good.

[0004] Therefore, a cutting machine for fixing thermoplastic processing is proposed to solve the problem that during this process, the sizes of thermoplastic mold embryos are different, and the surfaces of the mold embryos are not necessarily flat during the processing, so the stability of thermoplastic during cutting by the cutting machine is not good.

Specific embodiments

[0016] The present utility model will be further described below with reference to the drawings.

[0017] Please refer to Figures 1 - 3 A cutting machine for fixing thermoplastic plastic processing as shown, which includes a support plate 1. On both sides of the upper end of the support plate 1, limit plates 2 are fixedly connected. Chutes 3 are opened on the sides of the two limit plates 2 away from each other. A support block 4 is slidably connected in the chute 3. One side of the support block 4 is fixedly connected with a sliding frame 5. By setting the support block 4, the sliding frame 5 can be connected to the support plate 1 and the position of the sliding frame 5 can be changed. A first motor is fixedly connected to one side of the sliding frame 5. The output end of the first motor is fixedly connected with a bidirectional screw 6. Clamping plates 7 are threadedly connected to both sides of the bidirectional screw 6 away from each other. When the first motor drives the bidirectional screw 6 to rotate, the clamping plates 7 can move relatively. A first groove 8 is opened on the support plate 1. A first screw 9 is rotatably connected in the first groove 8 (a third motor is fixedly connected to the support plate 1 on one side of the first groove 8, and the output end of the third motor is fixedly connected with the first screw 9). A moving block 10 is threadedly connected to the first screw 9. When the third motor starts to drive the first screw 9 to rotate, the moving block 10 and the movable clamping plate 11 can move, thereby pushing the plastic mold blank to move. The upper end of the moving block 10 contacts the movable clamping plate 11. A cutting groove 12 is opened on the support plate 1. Electric push rods 13 are fixedly connected to one side of the upper ends of the two limit plates 2. The output end of the electric push rod 13 is fixedly connected with a connecting block 14. When the electric push rod 13 extends, it can drive the connecting block 14 to move up and down, so that the height of the cutting wheel 17 can be changed. A second motor is fixedly connected to one of the connecting blocks 14. The output end of the second motor is fixedly connected with a second screw 15. A moving frame 16 is threadedly connected to the second screw 15. A cutting wheel 17 is rotatably connected in the moving frame 16.

[0018] Among them, a movable clamping plate 11 is sleeved on the protrusion 18. The protrusion 18 is fixedly connected to the upper end of the moving block 10. By providing the protrusion 18, the movable clamping plate 11 can be limited, and the side of the plastic mold embryo away from the cutting groove 12 can be limited.

[0019] Among them, a positioning rod 19 is threadedly connected to the protrusion 18. The positioning rod 19 is inserted into the upper end of the movable clamping plate 11. By providing the positioning rod 19, the effect of replacing the movable clamping plate 11 with different lengths can be achieved through disassembly and installation, so as to adapt to the concave and convex surfaces of the mold embryo.

[0020] Among them, the support plate 1 is in contact with the support ball 20. The support ball 20 is rotatably embedded on the four sides of the bottom end of the movable clamping plate 11. By providing the support ball 20, the friction between the bottom side of the movable clamping plate 11 and the support plate 1 can be reduced.

[0021] Among them, a pulley 21 is rotatably connected to one side of the support block 4. A sliding ball 22 is rotatably embedded in the sliding frame 5. The sliding ball 22 is in contact with the sliding groove 3. By providing the pulley 21, the friction between the support block 4 and the sliding groove 3 can be reduced when the sliding frame 5 is manually pulled to move.

[0022] Working principle: Place the plastic mold embryo on the support plate 1. At this time, the first motor drives the bidirectional screw 6 to rotate, so that the two opposite clamping plates 7 can clamp the plastic mold embryo. At the same time, due to the existence of the sliding groove 3 and the support block 4, the sliding frame 5 can move, so as to select a suitable clamping position to clamp both sides of the plastic mold embryo. Then, the third motor drives the first screw 9 to rotate, so that the moving block 10 and the movable clamping plate 11 move, replace the movable clamping plate 11 with a suitable length, and limit it through the positioning rod 19. At this time, the rotation of the first screw 9 drives the movable clamping plate 11 and the plastic mold embryo to move, so that one side of the plastic mold embryo approaches the cutting groove 12, and the movable cutting wheel 17 is used to cut the plastic mold embryo to achieve a stable cutting effect.

[0023] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.

[0024] Other parts not detailed in the present invention belong to the prior art, so they will not be elaborated here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
