Description

[0001] The present invention relates to a deburring apparatus for injection molded product,

More particularly, the present invention relates to a deburring apparatus for injection molded articles, and more particularly to a method and apparatus for delivering an injection molded product, which is a rectangular plate, onto a conveying rail orthogonal to each other, and a burr formed on four sides of the transferred injection molded article To a deburring device for an injection molded article which can reduce the processing time of an injection molded article and improve the productivity by removing burrs by discharging hot air at a high temperature.

Injection molding is a method of producing an injection molded article by solidifying or hardening (curing) a melted material melted by heating in a mold filled with a mold.

Such injection molding has an advantage that a product having the same structure can be mass-produced, but burrs are generated at the time of injection molding.

Here, the burr is a portion molded together with an unnecessary portion in addition to the molded product during injection molding.

As such, the burr formed by injection molding is an obstacle to the production of the product, so it must be removed, and usually the burr is removed using a hand tool such as a chisel.

However, there is a problem that the burr removal operation manually performed is problematic in that the burr removal state is not constant depending on the operator, and a lot of labor is required to be input.

Accordingly, various burr removing apparatuses for removing burrs of injection molded articles have been developed.

FIG. 1 shows a conventional burr removing apparatus. The conventional burr removing apparatus 10 includes a fixing means 11 for fixing an injection molded article, a cutting means 12 for round-cutting the end of the injection molded article, And burr removing means 13 for removing the burrs on the surface of the wafer, and has the advantage that the quality of the same product can be ensured.

However, in the conventional burr removing apparatus 10, the burr removing means 13 is directly abutted against the injection-molded article to remove the defective product.

In addition, the conventional burr removing apparatus 10 may cause dust or the like during the burr removing operation to cause contamination of the product, and there is a problem that a safety accident may be caused to a worker due to fragment generated during processing.

In addition, the conventional burr removing apparatus 10 has a problem that the burr removing process is not continuously performed, and therefore it takes a long time in the burr removing process.
