High-strength carbon fiber upper cover mold

Abstract

The invention discloses a high-strength carbon fiber upper cover mold. The high-strength carbon fiber upper cover mold comprises an injection molding machine, a first female mold, a second female mold and a male mold; the first female mold and the second female mold are fixed on the injection molding machine; the male mold is driven to rotate by the injection molding machine, and is respectively closed with the first female mold and the second female mold; the male mold and the first female mold are closed to form a first injection mold for injecting hard plastic; the male mold and the second female mold are closed to form a second injection mold for injecting soft plastic; and carbon fiber products are arranged in the male mold. The high-strength carbon fiber upper cover mold can produce bicolor upper cover injection parts with PC plus carbon fibers and surrounded by TPE soft plastic on a large scale; and the produced plastic products are high in strength, beautiful and excellent in touch. The high-strength carbon fiber upper cover mold is excellent in exhaust, effectively solves the difficulty of easiness in air trapping in carbon fiber plastic injection, and improves the product yield. The injection products adopt bicolor injection molding, are excellent in bonding of soft and hard plastic, and are beautiful in surfaces. The mold is high in precision, is high in closing precision of two sets of molds in injection, and has no other defects such as burrs and bad exhaust.

Description

technical field [0001] The invention relates to the technical field of mold structures, in particular to a high-strength carbon fiber upper cover mold. Background technique [0002] The weight of carbon fiber is only one-third of that of alloy and iron, but its impact resistance is twice that of alloy and iron. The heat dissipation effect of carbon fiber is the best among the materials currently used. Due to the nature of its special materials, it has not been widely used in consumer electronics in the past few years. In the Twelfth Five-Year Outline, the country put forward the plan of "vigorously developing high-tech fibers", and put high-tech fiber materials related to national industrial safety as the top priority. [0003] At present, there are not many notebook top covers using carbon fiber in the market, and it is mainly used in high-end ultrabook series. However, since plastic products containing carbon fibers need to be molded at high temperatures, the mold is pro...
