[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0027] See Figures 1-4 , the utility model provides the following embodiments:

[0028] A device for cutting off excess edges and corners of injection molded accessories includes: a table 1 for operation, a mold base 5 installed on a rotating seat 3, a right-angle limit assembly and a cutter assembly, a rotating shaft 2 is provided on the rotating seat 3, the upper end surface of the rotating seat 3 is flush with the upper end surface of the rotating shaft 2, the rotating shaft 2 is installed on the table 1 through the shaft seat, and the position of the rotating seat 3 can be changed by changing the position of the shaft seat, a mold base 5 is provided on the top of the rotating seat 3, the rotating seat 3 and the mold base 5 are concentric, and are equipped with mold bases 5 of different sizes, so that it is suitable for cutting off edges and corners of circular injection molded parts of different sizes.

[0029] There are two groups of right-angle limit components set vertically. The right-angle sides of the right-angle limit components and the right-angle accessories are attached to each other, and the right-angle end of the right-angle accessory leaks out from between the two groups of right-angle limit components, which is convenient for the positioning of the right-angle accessory and will not block the resection part. A single right-angle limit component can be a straight sheet or more than two dispersed cylinders, and the dispersed cylinders are on the same straight line.

[0030] The vertical blade of the cutter assembly is used to cut the corners of cylindrical accessories, and the flat blade of the cutter assembly is used to cut the corners of right-angle accessories. It can simultaneously meet the needs of removing excess corners of circular injection molded parts and right-angle injection molded parts.

[0031] As another preferred solution of the present invention, a positioning block 4 is provided on the top surface of the rotating seat 3, and a positioning groove 7 for accommodating the positioning block 4 is provided on the bottom surface of the mold base 5. The positioning block 4 cannot rotate in the positioning groove 7. The mold base 5 and the rotating seat 3 designed in this way are easier to disassemble and replace.

[0032] As another preferred solution of the present invention, a positioning column 6 is provided on the top surface of the mold base 5. The positioning column 6 is adapted to the opening on the circular injection molded part and is used to position the circular injection molded part.

[0033] As another preferred embodiment of the present invention, in this embodiment, the two groups of right-angle limit components are a horizontal baffle 11 and a vertical baffle 12. The horizontal baffle 11 and the vertical baffle 12 are both straight sheets. The horizontal baffle 11 and the vertical baffle 12 are vertically arranged but do not intersect. The leakage between the horizontal baffle 11 and the vertical baffle 12 allows the right angle of the accessory to leak out.

[0034] As another preferred solution of the utility model, the cutter assembly is a multi-edge cutter 10. The vertical edge is the second cutting edge 103, and the flat edge is the first cutting edge 102. Both the second cutting edge 103 and the first cutting edge 102 are arranged on the tool holder 101. The second cutting edge 103 is on the vertical edge of the right angle of the tool holder 101, and the first cutting edge 102 is on the bottom surface of the tool holder 101. The first cutting edge 102 is in a right-angle shape.

[0035] As a preferred solution of the utility model, the cutter assembly is installed at one end of the connecting frame 9. The other end of the connecting frame 9 is installed on the table 1 through the air cylinder 8. The air cylinder 8 is used to control the up and down movement of the cutter assembly to perform right-angle edge cutting.

[0036] As a preferred solution of the utility model, a groove for accommodating the flat edge is provided on the table 1 to prevent damage to the first cutting edge 102.

[0037] When performing edge cutting on circular injection-molded fittings, the circular injection-molded fittings are installed on the mold base 5. The edge of the circular injection-molded fittings coincides with the edge of the mold base 5. Then, the mold base 5 is rotated, so that the mold base 5 drives the rotating seat 3 to rotate around the rotating shaft 2. The redundant corners are cut off by the second cutting edge 103 during the rotation. The operation is simple and convenient to use. The cutting efficiency is greatly improved, and the cutting effect is significantly improved.

[0038] When performing right-angle edge cutting, the two sides of the right-angle fitting with redundant edge materials are respectively attached to the horizontal baffle 11 and the vertical baffle 12, so that the right angle with edge materials leaks out between the horizontal baffle 11 and the vertical baffle 12. Then, the air cylinder 8 is controlled to drive the tool holder 101 to fall. During the falling process, the first cutting edge 102 cuts off the redundant right-angle edge materials.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
