Description

Technical Field

[0001] The utility model relates to the technical field of deburring of metal insert molding parts, in particular to a burr removal mechanism and equipment applied to the sealing position of metal insert molding parts. Background Art

[0002] When metal is implanted and molded, the position where the metal exposes the plastic is the sealing position of the mold. During molding, the outer contour surface of the metal must be closely attached to the mold to effectively prevent resin from overflowing. However, due to the dimensional tolerance of the metal part itself and the designed avoidance gap for implanting into the mold, resin will overflow at the sealing position during molding, forming burrs, that is, there are irregular plastic burrs at the sealing position of the injection molding sealing area between the plastic structure and the metal structure exposing the plastic. Currently, all plastic products of metal insert molding have such problems.

[0003] Currently, the post - process treatment method for burr defects is usually to manually scrape them off with a blade. The current manual deburring method has the following problems: the manual operation method cannot ensure consistency, the quality cannot be guaranteed, and there is a risk of missing processing and scratching the product; moreover, the manual deburring takes a long time. Due to the unstable quality, a full - inspection operation often needs to be added after processing, resulting in high costs. Summary of the Utility Model

[0053] Referring to Figures 1-6 , this embodiment provides a burr removal mechanism applied to the sealing position of a metal embedded molding part, including: a first cutter 1 and a second cutter 2 for removing burrs. The first cutter 1 and the second cutter 2 can be clamped on the outside of the product 3 and are arranged oppositely. The first cutter 1 and the second cutter 2 are respectively movably arranged on a first bracket 4 and a second bracket 5. The minimum gap d between the first cutter 1 and the second cutter 2 can be adjusted according to the product size requirement; the first bracket 4 and the second bracket 5 are respectively fixed on a rotating shaft 6, and the rotating shaft 6 is connected to a motor 7. The motor 6 is a servo motor, driving the burr removal mechanism to rotate.

[0054] In this embodiment, the first cutter 1 is hinged to the first bracket 4 to form a first hinge point 401. At the same time, on one side of the first hinge point 401, a first adjusting nut 402 is arranged between the first cutter 1 and the first bracket 4. The first adjusting nut 402 is passed through the first bracket 4 and installed together with the first cutter 1; the second cutter 2 is hinged to the second bracket 5 to form a second hinge point 501. At the same time, on one side of the second hinge point 501, a second adjusting nut 502 is arranged between the second cutter 2 and the second bracket 5. The second adjusting nut 502 is passed through the second bracket 5 and installed together with the second cutter 2; the first adjusting nut 402 and the second adjusting nut 502 respectively independently control the first cutter 1 and the second cutter 2, and are used to adjust the minimum gap d between the first cutter 1 and the second cutter 2.

[0055] In this embodiment, the first cutting tool 1 includes a first lever 101 and a first cutting edge 102 provided on the first lever 101. The second cutting tool 2 includes a second lever 201 and a second cutting edge 202 provided on the second lever 201. The first cutting edge 102 and the second cutting edge 202 serve to cut off burrs. The first lever 101 and the second lever 201 use the lever principle to transmit the spring force to the first cutting edge 102 and the second cutting edge 202. In this embodiment, the first bracket 4 and the second bracket 5 are the bracket parts of this burr cutting mechanism, fixing the first lever 101 and the second lever 201 on the rotating shaft 6, so that the first cutting edge 102 and the second cutting edge 202 rotate together with the rotating shaft 6.

[0056] In an embodiment of the present invention, the burr cutting mechanism provided in this embodiment can adjust the support heights of the first adjusting nut 402 and the second adjusting nut 502 according to the metal thickness at the position where the burr is cut, so as to limit the cutting depth of the cutting edge. Moreover, the first adjusting nut 402 and the second adjusting nut 502 can independently control the first cutting edge 102 and the second cutting edge 202. When there are burrs to be cut off only on one side of the product, the cutting edge on the other side can be lifted to avoid interference. This design can protect the appearance of the cut product.

Of course, the first blade 102 and the second blade 202 can also be fixed to the ends of the first lever 101 and the second lever 201 respectively by a snap-fitting method. The cutting edges of the first blade 102 and the second blade 202 are arc-shaped structures, so that the blades can slide smoothly on a plane. Furthermore, this burr removal mechanism can not only process the burrs on a cylindrical structure, but also be compatible with special-shaped structures such as ellipses. As a preferred embodiment, the positions where the first blade 102 is fixed to the first lever 101 and the second blade 202 is fixed to the second lever 201 can both be adjusted. For example, a plurality of screw holes are provided on the first blade 102 and the second blade 202, and the first blade 102 and the second blade 202 are installed at the required screw hole positions, so as to adjust the gap between the first blade 102 and the second blade 202.

[0060] When using the burr removal device for the sealing position of metal injection molding provided by the embodiment of the present invention, the steps are as follows: Place the product 3 in the product positioning carrier 9, hold the first lever 101 and the second lever 201, expand the distance between the first blade 102 and the second blade 202, push the jig together with the product to the processing position, and then release the first lever 101 and the second lever 201, so that the two blades clamp the root of the burr. Start the motor 7, and the motor 7 drives the burr removal mechanism to rotate reciprocally according to the set action to cut the burrs overflowing on the metal surface of the product. After the device stops, press the two levers to open the two blades, and withdraw the jig; then take out the product, and use an air gun or other tools to easily remove the burrs.
