[0028] It should be noted that the following detailed descriptions are all exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0029] The following is a detailed description of the utility model with reference to the accompanying drawings. The present embodiment discloses a mold processing and punching device, such as Figure 2 As shown, it includes a supporting shell 1, a first motor 4 is arranged in the supporting shell 1, the output end of the first motor 4 is connected to the first bevel gear 5, and second bevel gears 6 are arranged at both ends of the first bevel gear 5; one end of the second bevel gear 6 is connected to one end of the first screw rod 7, and the other end of the first screw rod 7 is rotatably connected to the inner wall surface of the supporting shell 1; a first moving block 8 is sleeved on the first screw rod 7, and the upper end of the first moving block 8 is connected to the second moving block 9;

[0030] A first slide groove 14 is provided at both ends of the upper surface of the support shell 1, and the second movable block 9 passes through the first slide groove 14.

[0031] When in use, the first motor 4 is powered on and started, driving the first bevel gear 5 to rotate, and the first bevel gear 5 drives the second bevel gears 6 at both ends to rotate, so that the first screws 7 at both ends rotate, and the first screw 7 rotates to drive the first moving block 8 to move horizontally, and then drives the second moving block 9 to move horizontally in the first slide 14, and the moving direction of the second moving block 9 is the direction of the mold, until it moves to the side of the second moving block 9 and is in close contact with the left and right end surfaces of the mold, and then stops moving. Then, the rotating handle 13 is twisted, and the rotating handle 13 rotates to drive the second screw 10 to rotate. Two third moving blocks 11 are set on the second screw 10, and the movement of the third moving block 11 drives the clamping block 12 to move, and the clamping blocks 12 at both ends gradually move together to clamp the front and rear ends of the mold. At this time, the front and rear ends and the left and right ends of the mold are clamped, which ensures the stability of the mold during drilling, avoids the mold from shaking during drilling, and ensures the accuracy of the mold drilling position.

[0032] Moreover, for molds with different widths at both ends, the utility model can also play a role in ensuring stability during drilling. After the second moving block 9 clamps the left and right ends of the mold, the spacing of the clamping blocks 12 is adjusted, that is, the spacing of a group of clamping blocks 12 at one end is large, and the spacing of a group of clamping blocks 12 at the other end is small, so that such molds can be clamped.

[0034] When in use, the electric telescopic rod 19 is powered on and started, driving the sliding plate 18 to move up and down along the sliding rod 17, and the second slide groove 16 assists the sliding plate 18 to slide, so that the sliding direction of the sliding plate 18 is accurate. The movement of the sliding plate 18 drives the drill bit 25 to move downward, even if the drill bit 25 moves toward the direction of the mold, the third motor 24 is powered on and started, driving the drill bit 25 to rotate, and then drilling the mold. After the drilling is completed, the electric telescopic rod 19 drives the sliding plate 18 to move upward, and then the second motor 20 is started, and the second motor 20 drives the third screw 21 to rotate, and the third screw 21 rotates and drives the fourth moving block 23 to move, and the drill bit 25 moves horizontally, changing the drilling position, and then the electric telescopic rod 19 is started again to make the drill bit 25 move downward, and the third motor 24 is started to achieve drilling at another position, that is, drilling at multiple positions on a plane is achieved, which improves the efficiency of mold drilling.

[0035] A placement plate 15 is provided in the middle of the upper surface of the support shell 1, and the placement plate 15 is detachably connected to the support shell 1.
