The cleaning plate 43 is a U-shaped structure, and a plurality of flushing nozzles 44 are obliquely installed on the side walls of the cleaning plate 43.

[0039] The matching gear 41 is meshedly connected with the vertical rack 42 . The side walls of the front rack 37 and the rear rack 38 are fixedly connected with a toothed belt 45 . The toothed belt 45 is meshedly connected with the adjacent matching gear 41 .

[0040] The front rack 37 is meshed and connected with the driving gear 35 , and the rear rack 38 is meshed and connected with the driving gear 35 . The rear rack 38 and the front rack 37 are respectively arranged at two sides of the driving gear 35 .

[0041] The T-shaped rack 6 is meshedly connected with the adjacent first gear 8, the first gear 8 is meshedly connected with the first rack 9, the first rack 9 is meshedly connected with the second gear 14, the second gear 14 is meshedly connected with the concave plate rack 10, and the multi-speed gear 11 is rotatably connected to the inner wall of the recess of the concave plate rack 10.

[0042] The speed gear 11 is meshed with the stationary rack 12, the speed gear 11 is meshed with the movable rack 13, the limit rod 17 and the inner wall of the rectangular hole 19 slide against each other, and the top wall of the base 1 is symmetrically fixedly connected with the limit block 33.

[0043] The displacement sensor 23 is electrically connected to the magnetic spring 28. The T-shaped plate 29 slides a certain distance and is connected to one of the grooves 30. The tooth groups on the side of the first rack 9 are arranged intermittently, that is, each tooth group is a plurality of continuous teeth, and a plurality of tooth groups are fixed to the side wall of the first rack 9.

[0044] In the present invention, after the casting of the metal mold is completed, the motor 34 is turned on. The motor 34 is a forward and reverse motor. When the output end of the motor 34 drives the driving gear 35 fixedly connected to it to rotate, the driving gear 35 will drive the front rack 37 meshing with it to move a distance to the right. The front rack 37 drives the first connecting rod 36 to move to the right through the corresponding return spring 15, and the driving gear 35 will also drive the second connecting rod 39 to move a distance to the left through the rear rack 38 and the corresponding return spring 15. Then the first connecting rod 36 will drive the T-shaped rack 6 fixedly connected to it to move synchronously, and the second connecting rod 39 will drive the T-shaped rack 6 fixedly connected to it to move synchronously, and the two T-shaped racks 6 move in opposite directions.

[0045] During the movement of each T-shaped rack 6, it will first slide inside the convex groove 21, and the displacement sensor 23 detects the movement displacement of the T-shaped rack 6. During the movement, the T-shaped rack 6 will drive the first gear 8 meshing with it to rotate a certain angle, and the first gear 8 drives the first rack 9 meshing with it to move upward, and the first rack 9 drives multiple second gears 14 to rotate, and each second gear 14 drives the concave plate rack 10 meshing with it to slide a certain distance, and the concave plate rack 10 drives the speed gear 11 to move synchronously. Since the speed gear 11 is meshed with the static rack 12 and the moving rack 13 respectively, the speed gear 11 will rotate during the movement. Rotation can also be generated during the process, thereby doubling the movement speed of the movable rack 13, then the movable rack 13 will drive the limit rod 17 to move synchronously and quickly, and the limit rod 17 will drive the seesaw 18 to rotate quickly through the rectangular hole 19, and by setting the rotation position of the circular shaft 16 on the seesaw 18, the seesaw 18 constitutes a lever structure, then the other end of the seesaw 18 will drive the knocking block 20 to knock the inner wall of the cavity 5 with increasing force, then in the demolding process of the metal mold, knocking the inner wall of the cavity 5 by multiple knocking blocks 20 can effectively knock and vibrate the mold, which is helpful to detach the metal forming workpiece in the mold cavity of the movable template 4 and improve the demolding effect.

[0046] Then, each tooth group intermittently arranged on the side wall of the first rack 9 will disengage from the corresponding second gear 14, and under the action of the displacement sensor 23, the magnetic spring 28 will be energized through its built-in controller. After being energized, the magnetic spring 28 will shrink for a certain distance, and then the magnetic spring 28 will drive the T-shaped plate 29 to move a certain distance, so that the T-shaped plate 29 is inserted into one of the grooves 30. Then, as the first rack 9 continues to move upward, it will drive the wedge block 26 to move synchronously through the T-shaped plate 29. The wedge block 26 drives the ejection column 24 to slide for a certain distance through the wedge-shaped hole 25 embedded and slidable with it, so that one end of the ejection column 24 slides in the inner cavity of the fixed template 3 and the movable template 4, pushing the formed metal parts to produce a slight displacement, which is convenient for the subsequent removal of the formed metal parts.

[0047] After the T-shaped rack 6 and the inner wall of the convex groove 21 are in contact with each other, one of the T-shaped racks 6 will drive the movable template 4 to move to the left, while the other T-shaped rack 6 will drive the movable template 4 to move to the right, until the movable template 4 is in contact with the limit block 33 after moving a certain distance. At this time, the movable template 4 is at the farthest end of its travel, and the operator can take out the formed metal mold.

[0048] At this time, since the front rack 37 and the rear rack 38 are still moving away from each other, and the movable template 4 is in a stationary state, the front rack 37 and the rear rack 38 will drive the toothed belt 45 to continue moving until it engages with the corresponding matching gear 41, so that the matching gear 41 rotates and drives the vertical rack 42 to move downward for a distance, then the vertical rack 42 will drive the cleaning plate 43 and multiple flushing nozzles 44 fixedly connected to its bottom to move downward for a distance, the flushing nozzle 44 is fixedly connected to the external water pipe, and then the mold is cleaned by the flushing nozzle 44.

[0049] Before the start of metal mold manufacturing, by turning on the motor 34, the output end of the motor 34 drives the driving gear 35 to rotate, and the driving gear 35 drives the front rack 37 and the rear rack 38 meshing with it to move, thereby driving the two movable templates 4 to approach each other at different distances, thereby changing the size of the inner cavity of the metal mold and expanding the application range of the metal mold.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
