[0020] See also Figure 1-Figure 4 The utility model provides a technical solution: a cutting device for mold manufacturing, comprising a cutting base 1, a cutting bracket body 2 is fixedly installed on the upper surface of the cutting base 1, a symmetrically distributed travel groove 3 is opened on the upper surface of the cutting base 1, a servo motor 4 is fixedly installed on the inner bottom wall of the cutting base 1, a worm 5 is fixedly installed on the output shaft of the servo motor 4 through a coupling, and bidirectional screws 6 are installed on the inner walls of both sides of the cutting base 1 through bearings;

[0021] The outer surface of the bidirectional screw rod 6 is provided with a fixing device, and the fixing device includes a worm wheel 7 , and the inner wall of the worm wheel 7 is fixedly sleeved with the outer surface of the bidirectional screw rod 6 .

[0022] Furthermore, the outer surface of the bidirectional screw rod 6 is threadedly connected with symmetrically distributed thread blocks 71, and the upper surface of the thread block 71 is fixedly connected with a support block 72. The servo motor 4 drives the worm 5 to rotate clockwise and counterclockwise. The rotation of the worm 5 drives the bidirectional screw rod 6 to rotate through the meshing worm wheel 7. The rotation of the bidirectional screw rod 6 drives the thread block 71 and the support block 72 to move through the limit cooperation of the stroke groove 3.

[0023] Furthermore, one end of the support block 72 passes through the travel groove 3 and extends to the upper surface of the cutting base 1. The upper surface of the support block 72 is fixedly connected to a mounting plate 73. A driving motor 74 is fixedly installed on one side surface of the mounting plate 73. The movement of the support block 72 drives the mounting plate 73 to move.

[0024] Furthermore, the output shaft of the driving motor 74 is fixedly installed with a screw 75 through a coupling, one end of the screw 75 penetrates and extends to the other side surface of the mounting plate 73, and the outer surface of one end of the screw 75 is threadedly connected with a threaded sleeve 76. The driving motor 74 drives the screw 75 to rotate clockwise and counterclockwise, and the rotation of the screw 75 drives the limited threaded sleeve 76 to perform telescopic movement.

[0025] Furthermore, the outer surface of the threaded sleeve 76 is fixedly connected to a first support 77 distributed in a ring array, the inner wall of the first support 77 is hinged with a swing rod 78 through a pin shaft, and the other side surface of the mounting plate 73 is provided with a limiting slide groove 79 distributed in a ring array. The telescopic movement of the threaded sleeve 76 drives the swing rod 78 to swing through the first support 77.

[0026] Furthermore, the inner wall of the limiting slide groove 79 is slidably connected to the limiting slider 710, and a movable baffle 711 is fixedly connected to a side surface of the limiting slider 710, and an arc-shaped support plate 712 is fixedly connected to a side surface of the movable baffle 711. The limiting slide groove 79 and the limiting slider 710 are used in coordination to achieve limiting movement through the movable baffle 711 cooperating with the arc-shaped support plate 712.

[0027] Furthermore, the inner surface of the arc-shaped support plate 712 is fixedly connected to a second support 713 , and the inner wall of the second support 713 is hinged to one end of the swing rod 78 via a pin shaft. The arc-shaped support plate 712 cooperates with the swing rod 78 to swing through the second support 713 .

[0028] Through the fixing device, the circular tubular mold can be stably clamped to avoid deviation caused by vibration during cutting. The operation is convenient and the cutting efficiency is improved. The circular tubular molds with different inner diameters can be fixed and clamped, thereby solving the problem that the mold is easily deviated due to vibration caused by cutting, thereby causing the cutting surface to be skewed, which not only increases the difficulty of cutting but also reduces the cutting efficiency.

[0029] Working principle: Step 1, when clamping, start the servo motor 4 to drive the worm 5 to rotate clockwise, the rotation of the worm 5 drives the bidirectional screw 6 to rotate through the meshing worm wheel 7, the rotation of the bidirectional screw 6 drives the two support blocks 72 to move relative to each other through the matching limit of the threaded block 71 and the stroke groove 3, so that its mounting plate 73 drives multiple arc support plates 712 to move, when the two ends of the circular tubular mold are respectively in contact with the moving baffle 711, the arc support plate 712 moves to the inside of the circular tubular mold, and the servo motor 4 stops working;

[0030] Step 2: Start the drive motor 74 to drive the screw 75 to rotate counterclockwise. The counterclockwise rotation of the screw 75 cooperates with the limited threaded sleeve 76 to retract the threaded sleeve 76. The retracting movement of the threaded sleeve 76 causes the first support 77 and the second support 713 to cooperate with the swing rod 78 to prop up, thereby driving the mobile baffle 711 and the arc-shaped support plate 712 to expand through the guidance of the limiting slide groove 79 and the limiting slider 710, so that the multiple arc-shaped support plates 712 are squeezed and supported by the inner wall of the circular tube mold, thereby achieving stable clamping and fixing of the two ends of the circular tube mold;

[0031] Step three, after the cutting is completed, start the drive motor 74 to drive the screw 75 to rotate clockwise, so that the threaded sleeve 76 extends, thereby causing the multiple arc-shaped support plates 712 to retract and separate from the inner wall of the circular tubular mold. Then start the servo motor 4 to drive the worm 5 to rotate counterclockwise, so that the two mounting plates 73 move away from each other and separate, and the cut circular tubular mold can be removed.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
