[0022] The utility model is further described as follows in connection with the drawings and specific embodiment:

[0023] Reference Figs. 1 to 4The utility model provides a kind of injection molding part cutting grain tool, including tool main body 1 and be equipped on tool main body blade 2, the upper surface of tool main body 1 is equipped with processing surface 11, the processing surface 11 is formed by two plane 111 intersection and has an angle, the angle range is 150 °-170 °, preferably 160 °.

[0024] In the embodiment, the width of the tool main body in the direction perpendicular to the intersection line of the two planes is 152 mm, the height is 53.1 mm, and the length in the direction parallel to the intersection line of the two planes is 215 mm.

[0025] The tool main body 1 is provided with a blade mounting groove, and a detachable blade fixing block 3 is arranged in the blade mounting groove. The blade 2 is arranged on the blade fixing block 3. Specifically, the blade is arranged on the intersection line of the two planes, and the cutting edge of the blade is arranged along the extension direction of the intersection line.

[0026] To facilitate the installation and replacement of the blade, the following detachable structure is adopted. Specifically, a strip-shaped sliding groove is arranged on the groove bottom of the blade mounting groove, a strip-shaped protrusion is arranged on the side surface of the blade fixing block matched with the blade mounting groove, and the strip-shaped sliding groove and the strip-shaped protrusion are matched to facilitate the installation of the blade fixing block. At the same time, an installation hole is arranged on the groove wall of the blade mounting groove in the extension direction of the strip-shaped sliding groove, a strip-shaped through hole 31 parallel to the strip-shaped sliding groove is arranged in the middle of the blade fixing block 3, and a screw is threadedly connected with the installation hole through the strip-shaped through hole 31 to fix and install the blade fixing block in the blade mounting groove, so as to fix the blade fixing block in the blade mounting groove and avoid the movement of the blade fixing block during processing, which in turn drives the blade to deviate and affects the processing precision. The specification of the screw is M8X55L.

[0027] The length of the blade fixing block in the extension direction of the strip-shaped sliding groove is 50.1 mm, the height is 53.1 mm, and the length perpendicular to the extension direction of the strip-shaped sliding groove is 40 mm.

[0028] The blade 2 is detachably installed on the blade fixing block 3 by means of screws or other methods, at least two screws are used to avoid movement. Of course, welding or other methods can also be used to fix it. When the blade is not sharp enough or damaged, only the blade needs to be replaced, without the need to replace the entire structure, improving the utilization rate of the structure.

[0029] Preferably, the distance of the plane in the direction perpendicular to the intersection line is matched with the size of the injection molding part to be cut. In this way, the injection molding part to be cut can be completely attached to the plane, ensuring the stability of the cutting process.

[0030] The two extension surfaces connected with the two planes of the processing surface respectively form an angle in the range of 110-130 degrees, preferably 120 degrees.

Since the processing surface has an angle, after abutting against the processing surface, the originally adjacent gap between the two adjacent injection molding parts becomes V-shaped opening. At this time, the processing personnel only need to move the product along the blade edge direction of the blade and pass through the blade edge to complete the separation of the two adjacent injection molding parts. This method can effectively reduce the phenomenon of blade scratching the injection molding parts and ensure the product quality.
