Abstract

The invention provides a device and method for forming metal flash products directly through ultrasonic-assisted injection molding. The device comprises a guide column, a fixed mold fixing plate, a fixed mold, a moving mold and others. The fixed mold is fixedly connected with the fixed mold fixing plate through a connection piece. A sprue bush is further arranged between the fixed mold fixing plate and the fixed mold. The upper end of the sprue bush is arranged on the fixed mold fixing plate. The lower end of the sprue bush is arranged on the fixed mold. A main runner is arranged on the sprue bush, the moving mold is arranged on the lower portion of the guide column in a sleeving mode, and a cushion block is arranged between the moving mold and a moving mold fixing plate. Moreover, the moving mold is connected with the cushion block and the moving mold fixing plate through connection pieces, a push plate is connected with the moving mold fixing plate, and a push rod is connected with a push plate fixing plate. A reset rod is connected with the push plate fixing plate which is connected with the push plate through a connection piece, and an ultrasonic-assisted injection device is arranged between the moving mold and the push plate fixing plate. The ultrasonic-assisted injection device comprises an energy converter, an amplitude transformer and an ultrasonic generator. The upper end face of the amplitude transformer can be in direct contact with plastic blend melt. The device and method for forming the metal flash products directly through ultrasonic-assisted injection molding save energy and lower cost.

Description

technical field [0001] The invention relates to an ultrasonic-assisted injection molding device and a molding method thereof, which belong to an innovative technology of an ultrasonic-assisted injection molding direct molding metal flash product device and a molding method thereof. Background technique [0002] At present, the metallic luster effect on the surface of the product is mostly achieved through subsequent surface coloring processes such as spraying and paint testing. Although high-gloss aluminum powder, copper gold powder, etc. have been widely used in industrial fields, their main application is in coatings, accounting for about 85%, ink applications account for about 9%, plastic applications account for about 4%, and other applications account for about 2%. The blending of high-gloss aluminum powder and thermoplastic resin is a typical composite material with metallic luster, which can be directly injection molded into plastic products with metallic luster, an...
