摘要： A flash removing method whereby flash is cut off by a reamer which is freely movable while being in contact with polymeric molded products within a predetermined range of pressing force. The reamer is provided with blades having normal clearance angles of substantially zero degree and the flanks of the blades follow the flash-forming region. The reamer is controlled in radial position according to the shape of the polymeric molded product, so that the reamer always receives a constant radial load from the product to leave even traces after the flash removal. A solidified gate is cut off before the flash removal. A flash removing apparatus for performing the method.

摘要： This invention discloses a die opening device for a molding machine. One upper die segment is attached to the underside of an upper die plate tiltable relative to the surface of a floor on which the molding machine is installed and, at the same time, one lower die segment is opposed to the upper die segment and attached to a lower die plate adapted to be reciprocated vertically in a substantially perpendicular direction by a hydraulic cylinder. The upper die plate and the lower die plate are cooperatively connected to each other with connection means in such a manner that a descent of the lower die plate will tilt the upper die plate and raise the worker side thereof. Owing to the inclination thus produced, the molding groove in the upper die segment is opposed to the worker.
