DETAILED DESCRIPTION OF THE EMBODIMENTS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, the utility model provides a technical solution: an edge grinding device for mechanical mold manufacturing, including a grinding frame 1. A connecting frame 2 is fixedly connected between the inner walls of the grinding frame 1. An L-shaped plate 3 is arranged inside the grinding frame 1, and a first motor 4 is fixedly connected to the inner wall of the L-shaped plate 3. The output end of the first motor 4 is fixedly connected to a grinding roller 5. A moving mechanism 8 is arranged between the top end of the L-shaped plate 3 and the inner wall of the connecting frame 2. A pair of knocking and vibrating mechanisms 9 are arranged between the inner wall and the outer wall of the connecting frame 2. And a telescopic shielding mechanism 10 is arranged on the outer wall of the connecting frame 2. A pair of clamping plates 7 are arranged inside the grinding frame 1, and a plurality of first electric telescopic rods 6 are fixedly connected between the ends of the pair of clamping plates 7 away from each other and the inner wall of the grinding frame 1.

[0024] According to the overall structure of the device, the mechanical mold is placed vertically in the grinding frame 1. Multiple pairs of first electric telescopic rods 6 drive the pair of clamping plates 7 to move towards each other to clamp and fix the mechanical mold. And the first motor 4 drives the grinding roller 5 to rotate to grind the edge of the mechanical mold, removing the burrs in the edge area and making the edge area of the mechanical mold smooth.

[0025] As Figure 1 and Figure 2 shown in the figure, the moving mechanism 8 includes a second motor 801 fixedly connected to the outer wall of the connecting frame 2. A pair of rotating rods 802 are rotatably connected to the outer wall of the connecting frame 2 through bearings and rotating shafts. And one end of the rotating rod 802 on one side is fixedly connected to the output end of the second motor 801. Pulley wheels 803 are sleeved on the outer walls of the pair of rotating rods 802, and a transmission belt 804 is connected between the pair of pulley wheels 803 in a transmission manner. A moving plate 805 is fixedly connected to the bottom end of the transmission belt 804, and a second electric telescopic rod 806 is fixedly connected to the bottom end of the moving plate 805. The bottom end of the second electric telescopic rod 806 is fixedly connected to the top end of the L-shaped plate 3. An inner rod 807 is fixedly connected to the inner wall of the connecting frame 2. A moving sleeve block 808 is arranged inside the connecting frame 2, and a sleeve hole is drilled in the inner wall of the moving sleeve block 808. The moving sleeve block 808 is sleeved on the outer wall of the inner rod 807 through the sleeve hole. A pair of round rods 809 are fixedly connected between the bottom end of the moving sleeve block 808 and the top end of the moving plate 805.

[0026] Through the setting of the moving mechanism 8, the second electric telescopic rod 806 drives the L-shaped plate 3 to move downward, causing the first motor 4 and the grinding roller 5 to move downward until the grinding roller 5 contacts the edge of the mechanical mold. Then, the second motor 801 drives the conveyor belt 804 to move through a pair of rotating rods 802 and a pair of pulleys 803. The conveyor belt 804 drives the moving plate 805 to move synchronously with the assistance of the moving sleeve block 808 and the built-in rod 807. The moving plate 805 drives the second electric telescopic rod 806 and the L-shaped plate 3 to move, causing the first motor 4 and the grinding roller 5 to move along the edge of the mechanical mold, prompting the grinding roller 5 to grind while moving, removing the burrs in the edge area, and keeping the edge area of the mechanical mold smooth.

[0027] As Figure 1 , Figure 2 , and Figure 4 shown, a pair of knocking and vibrating mechanisms 9 both include eccentric wheels 901 sleeved on the outer wall of the rotating rod 802. A circular plate 902 is arranged on the outer wall of the eccentric wheel 901 and is in contact with it. A movable plate 903 is fixedly connected to the outer wall of the circular plate 902. A fixed plate 904 is fixedly connected to the outer wall of the connecting frame 2. A circular hole is drilled at one end of the fixed plate 904. A movable rod 906 is arranged on one side of the movable plate 903. One end of the movable rod 906 passes through the circular hole and is fixedly connected to one end of the movable plate 903. A knocking ball 907 is fixedly connected to the other end of the movable rod 906, and the knocking ball 907 is located inside the grinding frame 1. A spring 905 is sleeved on the outer wall of the movable rod 906, and both ends of the spring 905 are fixedly connected to the opposite sides of the movable plate 903 and the fixed plate 904 respectively.

[0028] Through the setting of the knocking and vibrating mechanism 9, when a pair of rotating rods 802 rotate, they drive a pair of eccentric wheels 901 to rotate synchronously. During the rotation of the eccentric wheels 901, first, the eccentric end of the eccentric wheel 901 squeezes the circular plate 902 and the movable plate 903 to move towards the fixed plate 904, compressing the spring 905, and driving the movable rod 906 and the knocking ball 907 to separate from the inner wall of the grinding frame 1. Then, the eccentric end of the eccentric wheel 901 continues to rotate. After separating from the circular plate 902, the circular plate 902 and the movable plate 903 that lose the extrusion are reset under the elastic reset action of the spring 905, driving the movable rod 906 and the knocking ball 907 to contact and collide with the inner wall of the grinding frame 1. Repeating this process generates vibration, and the vibration is used to shake off the debris adhering to the inner walls of the grinding frame 1 and the telescopic shield 1003, so that the debris fully falls onto the bottom end inside the grinding frame 1, facilitating subsequent centralized cleaning, reducing the cleaning area, reducing the cleaning difficulty, making the cleaning of the debris more convenient, and improving the cleaning efficiency.

[0029] As Figure 1 , and Figure 5As shown in the figure, the telescopic shielding mechanism 10 includes a pair of telescopic cylinders 1001. The outer walls of the pair of telescopic cylinders 1001 are fixedly connected to the outer wall of the grinding frame 1. The output ends of the pair of telescopic cylinders 1001 are fixedly connected with side plates 1002. The top of the grinding frame 1 is fixedly connected with a telescopic shield 1003. The outer walls of the telescopic shield 1003 are fixedly connected to one ends of the pair of side plates 1002 close to each other. The telescopic shield 1003 is transparent, and a heat insulation layer is provided on the inner wall of the telescopic shield 1003.

[0030] Through the arrangement of the telescopic shielding mechanism 10, during grinding, the pair of telescopic cylinders 1001 push the side plates 1002 upward, enabling the telescopic shield 1003 to extend upward to block the top of the grinding frame 1, preventing debris from splashing everywhere outside the grinding frame 1 during the grinding process. Moreover, due to the arrangement of the heat insulation layer, when the debris carrying heat adheres to the inner wall of the telescopic shield 1003, it is not easily damaged by high temperature. And during the grinding process, the staff can observe the grinding condition of the edge area of the mechanical mold inside the grinding frame 1 in real time through the transparent telescopic shield 1003, which is convenient for replacing the grinding area and the mechanical mold.

[0031] Working principle: First, place the mechanical mold vertically in the grinding frame 1. Multiple pairs of first electric telescopic rods 6 drive a pair of clamping plates 7 to move towards each other to clamp and fix the mechanical mold. Then, the second electric telescopic rod 806 drives the L-shaped plate 3 to move downward, causing the first motor 4 and the grinding roller 5 to move downward until the grinding roller 5 contacts the edge of the mechanical mold. Immediately afterwards, the telescopic cylinder 1001 pushes the side plate 1002 upward, causing the telescopic shield 1003 to extend upward, increasing the top of the grinding frame 1. After the extension ends, the second motor 801 drives the transmission belt 804 to move through a pair of rotating rods 802 and a pair of pulleys 803. Accordingly, the moving plate 805 moves synchronously and drives the moving sleeve block 808 to move along the built-in rod 807 for assistance. Moreover, the second electric telescopic rod 806 and the L-shaped plate 3 also move accordingly. At this time, the first motor 4 drives the grinding roller 5 to rotate and, driven by the L-shaped plate 3, moves from one side to the other along the edge of the mechanical mold, achieving grinding while moving. Moreover, when the pair of rotating rods 802 rotate, they drive a pair of eccentric wheels 901 to rotate synchronously. During the rotation of the eccentric wheels 901, first, their eccentric ends squeeze the circular plate 902 and the movable plate 903 to move towards the fixed plate 904, compress the spring 905, and drive the movable rod 906 and the knocking ball 907 to separate from the inner wall of the grinding frame 1. Then, the eccentric ends of the eccentric wheels 901 continue to rotate. After separating from the circular plate 902, the circular plate 902 and the movable plate 903 that lose the extrusion are reset under the elastic reset action of the spring 905, driving the movable rod 906 and the knocking ball 907 to contact and collide with the inner wall of the grinding frame 1. Repeating this process generates vibration, vibrating off the debris adhering to the inner walls of the grinding frame 1 and the telescopic shield 1003, causing it to fully fall onto the bottom end inside the grinding frame 1 for debris collection. After one edge area is ground, the staff takes the mechanical mold and switches its position to grind the other unground edge areas.

[0032] The wiring diagrams of the first motor 4, the first electric telescopic rod 6, the second motor 801, the second electric telescopic rod 806, and the telescopic cylinder 1001 in this solution belong to the common knowledge in the field. Their working principles are already well-known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the first motor 4, the first electric telescopic rod 6, the second motor 801, the second electric telescopic rod 806, and the telescopic cylinder 1001 will not be explained in detail.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
