Top cropping mould for car decorative part with strip-shaped abnormal section

The invention discloses a top cropping mould for a car decorative part with a strip-shaped abnormal section, which is used for solving problems that the existing top cropping mould is low in production efficiency, high in processing cost and long in production period. The top cropping mould comprises two top croppingmould units and a middle material supporting block, wherein the two top cropping mould units are identical in structure and are arranged on the left side and the right side, and the arranging angle of the two top cropping mould units is matched with arcs of the two ends of a work piece; and the arranging position of the two top cropping mould units is matched with the length dimension of the work piece. The top cropping mould has the characteristics of reliable performance, rational structure, and convenience in operation, so that not only the production efficiency and product quality are greatly improved, but also the manufacturing cost for the mould and products is reduced.
