Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for removing burrs generated on a synthetic resin molded body.

[Conventional technology]

The synthetic resin molded body is molded using thermoplastic resin or thermosetting resin such as plastic, vinyl, or polyethylene.

However, during processing, the resin flows into the gaps between parts of the mold, such as the dividing surface of the mold and the mating surface with the slide core, resulting in burrs being formed in the parts of the molded product. , the burrs had to be removed from the molded product at the end of processing.

The work of removing burrs from a molded object must be done without damaging the molded product, so it must be done manually, and the above work is laborious and time-consuming, especially when removing burrs from molded products with complex shapes. There was a problem in that the work had to be done by a skilled person.

The present invention was made from the viewpoint of ridges, and its purpose is to provide a device that automatically removes burrs generated on a synthetic resin molded body in a short time without manual intervention. This is what I am trying to do.

[Means for solving problems]

The above object is to provide a workbench for holding a synthetic resin molded body to be deburred, a coolant injection nozzle supported movably relative to the synthetic resin molded body,
A vibrating cutter having a vibrating device and supported movably relative to the synthetic resin molded body, the coolant injection nozzle, and the vibrating cutter can be moved along a burr-generating portion of the synthetic resin molded body. This is achieved by a deburring device that includes a control device, a device that supplies coolant to the coolant injection nozzle, and a power supply circuit that operates the vibrator.

[For production]

With the above configuration, burrs generated on a synthetic resin molded product can be automatically and quickly removed without damaging the molded product.
