[0002] A die-casting shell is a shell manufactured through a die-casting process, and is usually used in fields such as electronic products, mechanical equipment, and automotive parts. Die-casting is a process of pouring molten metal into a mold and forming it through high pressure and cooling, and can manufacture shells with complex shapes and structures. During the production of die-casting shells, burrs are likely to appear on the opening surface of the die-casting shell.

[0003] During the process of grinding a die-casting shell, it is necessary to grind the boundary of the opening surface of the die-casting shell. However, traditional grinding wheels are usually for planar grinding, and it is difficult to grind to the inner corner position of the opening surface of the shell, resulting in a poor grinding effect on the die-casting shell. Burrs are likely to remain at the inner corner of the opening surface of the die-casting shell. When the burrs are not ground clean, it is likely to affect the installation and splicing of the die-casting shell.

[0004] Therefore, the utility model provides a die-casting shell grinding device. Summary of the Utility Model

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The following gives specific embodiments.

[0025] Such as Figure 1 And Figure 4As shown in the figure, a die-casting shell grinding device according to an embodiment of the present utility model includes a grinding machine body 1; a support frame 2 is arranged inside the grinding machine body 1 through an adjusting component; a support frame 3 is fixedly connected inside the support frame 2; the support frame 3 is arranged at the position corresponding to the corners of the support frame 2, and the support frame 3 is arranged at the positions on both sides of the support frame 2, and a support roller 4 is rotatably connected between two support frames 3 corresponding to one corner; a grinding belt 5 is connected between multiple support rollers 4; the top of the support frame 2 is connected with a pushing block 6 through an electric push rod; the pushing block 6 is arranged at the position corresponding to the support frame 2; during work, when it is necessary to grind the die-casting shell, the die-casting shell can be placed into the grinding machine body 1, and then the support roller 4 can be driven to rotate by a driving motor, so that the support roller 4 drives the grinding belt 5 to rotate to grind the die-casting shell. At the same time, during the grinding process, the pushing block 6 can be pushed by the electric push rod, so that the pushing block 6 pushes the grinding belt 5 to move downward, so that the grinding belt 5 can grind the inner corners of the opening surface of the die-casting shell, so that the grinding effect on the die-casting shell is better.

[0026] As Figures 1 to 3 shown, a through hole is opened inside the grinding machine body 1, and a dust-proof net 7 is fixedly connected inside the through hole; a rotating shaft 8 is rotatably connected inside the grinding machine body 1; multiple air extraction fans 9 are fixedly connected to the side wall of the rotating shaft 8, and the air extraction fans 9 are arranged in a circumferential array pattern on the side wall of the rotating shaft 8; a scraping plate 801 is fixedly connected to the end of the rotating shaft 8; the scraping plate 801 is in contact with the side wall of the dust-proof net 7; a collection hopper 10 is slidably fitted inside the grinding machine body 1; the collection hopper 10 is arranged at the position corresponding to the bottom of the dust-proof net 7; during work, when grinding the die-casting shell, the rotating shaft 8 can be driven to rotate the air extraction fans 9 to extract the debris generated during grinding inside the grinding machine body 1. After the debris moves to the position corresponding to the dust-proof net 7, it will fall into the collection hopper 10 to collect the debris, making the grinding environment of the die-casting shell cleaner. At the same time, during the rotation of the rotating shaft 8, the collection hopper 10 can be driven to rotate together to clean the debris adhered to the surface of the dust-proof net 7, so as to effectively avoid the situation that the debris blocks the dust-proof net 7.

[0027] As Figure 1 with Figure 4As shown in the figure, the adjusting component includes an adjusting frame 11; the adjusting frame 11 is slidably connected to the inside of the grinding machine body 1; the support frame 2 is slidably connected to the inside of the adjusting frame 11; the sliding directions of the adjusting frame 11 and the support frame 2 are perpendicular to each other; a guide rod 12 is fixedly connected to the top of the adjusting frame 11; the guide rod 12 is parallel to the sliding direction of the adjusting frame 11; the guide rod 12 is slidably connected to the inside of the grinding machine body 1; during operation, when it is necessary to grind the die-cast housing, the adjusting frame 11 can be controlled to slide inside the grinding machine body 1, and at the same time, the support frame 2 can be controlled to slide inside the adjusting frame 11, so that the grinding belt 5 can better contact the die-cast housing, thereby making the grinding effect on the die-cast housing better. At the same time, during the sliding process of the adjusting frame 11, the sliding of the guide rod 12 is restricted by the grinding machine body 1, which can make the sliding of the adjusting frame 11 more stable.

[0028] As Figures 4 to 5 shown, an anti-wear roller 13 is rotatably connected to the inside of the pushing block 6; the anti-wear roller 13 contacts the top of the grinding belt 5; during operation, when the pushing block 6 is used to push the grinding belt 5, by arranging the anti-wear roller 13 inside the pushing block 6, the friction between the pushing block 6 and the grinding belt 5 can be made smaller, and the wear between the pushing block 6 and the grinding belt 5 can be reduced.

[0029] As Figure 6 shown, a positioning block 14 is fixedly connected to the side wall of the support roller 4; the positioning block 14 is rotatably connected to the inside of the support frame 3; during operation, when the support roller 4 rotates inside the support frame 3, by arranging the positioning block 14 on the support roller 4 and restricting the rotation of the positioning block 14 by the support frame 3, the situation of the support roller 4 tilting less during rotation can be made, and the rotation of the support roller 4 can be made more stable.

[0030] As Figure 6 shown, a plurality of anti-wear balls 15 are arranged between the support frame 3 and the positioning block 14; the side walls of the anti-wear balls 15 are in contact with the side walls of the support frame 3 and the positioning block 14; during operation, when the positioning block 14 rotates inside the support frame 3, by arranging the anti-wear balls 15 between the support frame 3 and the positioning block 14, the sliding friction between the support frame 3 and the positioning block 14 can be changed into rolling friction, making the friction between the support frame 3 and the positioning block 14 smaller, and thus reducing the wear between the support frame 3 and the positioning block 14.

[0031] During operation, when it is necessary to grind the die-cast housing, the die-cast housing can be placed inside the grinding machine body 1. Then, the driving motor can be used to drive the support roller 4 to rotate, so that the support roller 4 drives the grinding belt 5 to rotate, and the die-cast housing is ground. At the same time, during the grinding process, the electric push rod can be used to push the push block 6, so that the push block 6 pushes the grinding belt 5 downward, so that the grinding belt 5 can grind the inner corner of the opening surface of the die-cast housing, thus making the grinding effect of the die-cast housing better.

[0032] When grinding the die-cast housing, the rotating shaft 8 can be used to drive the exhaust fan 9 to rotate, so as to extract the debris generated by grinding inside the grinding machine body 1. After the debris moves to the position corresponding to the dust-proof net 7, it will fall into the collection hopper 10 to collect the debris, making the grinding environment of the die-cast housing cleaner. At the same time, during the rotation of the rotating shaft 8, the collection hopper 10 can be driven to rotate together to clean the debris adhered to the surface of the dust-proof net 7, thus effectively avoiding the situation that the debris blocks the dust-proof net 7.

[0033] When it is necessary to grind the die-cast housing, the adjustment frame 11 can be controlled to slide inside the grinding machine body 1, and at the same time, the support frame 2 can be controlled to slide inside the adjustment frame 11, so that the grinding belt 5 can better contact the die-cast housing, thus making the grinding effect of the die-cast housing better. At the same time, during the sliding of the adjustment frame 11, the sliding of the guide rod 12 by the grinding machine body 1 can be restricted, making the sliding of the adjustment frame 11 more stable.

[0034] When pushing the grinding belt 5 by the push block 6, by setting the anti-wear roller 13 inside the push block 6, the friction between the push block 6 and the grinding belt 5 can be made smaller, and the wear between the push block 6 and the grinding belt 5 can be reduced.

[0035] When the support roller 4 rotates inside the support frame 3, by setting the positioning block 14 on the support roller 4 and restricting the rotation of the positioning block 14 by the support frame 3, the situation of the support roller 4 tilting less during rotation can be made, making the rotation of the support roller 4 more stable.

[0036] When the positioning block 14 rotates inside the support frame 3, by setting the anti-wear ball 15 between the support frame 3 and the positioning block 14, the sliding friction between the support frame 3 and the positioning block 14 can be changed into rolling friction, making the friction between the support frame 3 and the positioning block 14 smaller, and thus reducing the wear between the support frame 3 and the positioning block 14.
