Document Type and Number:
WIPO Patent Application WO/2021/120441
Kind Code:
A1
Abstract:
The present invention relates to the technical field of molds, and relates to a mold for preparing a composite profile. The mold is formed by assembling and fixing multiple mold plates, and comprises a cavity, a melt adhesive passage, a melt passage, and a mold outlet. The multiple mold plates at least comprise an inlet template, a melt adhesive template, a melt template, and an outlet template. An inlet for a metal core material is provided on an end face of the inlet template, and the mold outlet is provided on an end face of the outlet template. In the present invention, a melt casting space and a melt adhesive casting space are configured to be spaced apart from each other by a certain distance, i.e., 0.5-2 cm; the configuration of the distance can promote the fusion of a coating layer and a melt adhesive layer at the interface therebetween; and such fusion can promote the coating layer to be more firmly attached to the metal core material.
