Abstract
A method and an injection mold for the production of profiled and at least partially elongated components out of liquid or viscous solidifying molding compounds, by said injection mold, the molding compound being injected into the mold cavity and transported away under steady extension of the mold cavity and under steady elongation of the component to be formed after the initial filling of the mold cavity. The molding compound transported away is transported out of the mold while molding compound is continuously being injected until the forming component reaches its final length. The mold has at least one mold insert whose surface is part of the peripheral surface of the mold cavity and which is supported in the mold in a movable way in longitudinal direction of the component to be formed so that the mold cavity forming the component can be expanded to the desired size and shape of the component inside and outside of the mold by a movement of the mold insert. Thus the invention makes it possible to produce components that have complex contours, are elongated, at least partially, and have a finite size in a high quality at a low expenditure.
