Abstract
An automatic flash removing apparatus, according to the present invention, comprises a flash removing cutter edge carried by a cutter holder. The cutter holder is movable with carrying the cutter edge relative to a molded product. On the other hand, the molded product is supported on a product support which can drive the product relative to the cutter edge so that the portion of the product having flash to be removed is placed in opposition to the cutter edge. The cutter holder is associated with a pressure regulator means for adjusting pressure to depress the cutter edge toward the product. Regulated depression pressure may avoid fluctuation of smoothness of the product after removing the flash.

An apparatus for removing flash from a molded product comprising:
- a cutter means;
- a cutter carrier means for carrying said cutter means to a predetermined working position at which flash is removed from said molded product, said carrier means being supported in free movement;
- a work carrier means for holding said molded product, for moving said molded product to said working position and for shifting said molded product relative to said cutting means at said working position to establish contact between a portion of said molded product where flash thereof is to be removed and said cutter means;
- and
- means for depressing said cutter means onto said portion of said molded product with a predetermined magnitude of force.
An apparatus for removing flash from a molded product comprising:
- a cutter means having a cutter edge:
- a cutter carrier means carrying said cutter means and movable in vertical and horizontal directions;
- a work carrier means holding said molded product to carry to said working position and shifting said molded product at said working position to establish contact between a portion of said molded product, where flash thereof is to be removed, and said cutter means;
- a servo means, associated with said work carrier means, for driving said work carrier means so as to sift said portion of the product in such a manner that said cutting edge of said cutter means continuously maintains contact with flash to be removed;
- and
- means for depressing said cutter means onto said portion of said molded product with a predetermined magnitude of force.
An apparatus for removing flash from a molded product comprising:
- a cutter means;
- a support;
- a cutter carrier means for carrying said cutter means, and said cutter carrying means being supported on said support for free movement with respect thereto, said cutter carrier means being movable relative to said molded product in such a manner that said cutter means is oriented in cutting engagement with the flash and is movable along a circumferential surface of said product while maintaining cutting engagement;
- and
- a work carrier means for holding said molded product, for carrying said molded product to said working position and for shifting said molded procut at said working position to establish said cutting engagement between said flash and said cutter means, said work carrier means driving said molded product so as to cause relative displacement between said cutter means and said product along said flash through the entire circumference of said product.
