MOLDING INSERT ASSEMBLY, MOLDING DEVICE AND MOLDING METHOD Russian patent published in 2022 - IPC B29C43/42 

FIELD: molding.

SUBSTANCE: invention relates to a method for manufacturing a component with a set of cavities. The method for manufacturing a component with a set of cavities passing through the specified component is described, while each cavity has at least one surface with a complex contour, which includes providing the first molding insert having the first main plate and a set of the first protruding molding segments protruding from the first main plate and located at a distance from each other; providing the second molding insert having the second main plate and a set of the second protruding molding segments protruding from the second main plate and located at a distance from each other; molding the component with filling each cavity of the specified set of cavities with the first protruding molding segment extending from the first molding insert, and the second protruding molding segment extending from the second molding insert, with stacking the first and the second molding inserts in such a way that the second main plate overlaps the first main plate, and the first protruding molding segments extending from the first molding insert pass through the second main plate of the second molding insert; separating the first and the second molding inserts from the molded component after that, with the retention of protruding molding segments of the first and the second molding inserts by their corresponding main plates, wherein each cavity of the specified set of cavities has at least one surface with a negative taper angle relatively to the first and the second main plates.

EFFECT: ensuring the molding of components with a set of cavities passing through the specified component, including components, in which some or all cavities have at least one surface with a complex contour.
