Embodiment Construction
[0046] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0047] refer to figure 1 , is a schematic structural view of a carbon fiber composite plastic product in an embodiment of the present invention. In this embodiment, the plastic product 1 is a notebook computer case. Wherein, the plastic product 1 includes a shell 11 and an assembly structure 12 (such as an undercut, a side hole, etc.) on the shell 11 . Both the casing 11 and the assembly structure 12 are made of carbon fiber composite material through injection molding. Among them, due to the excellent electrical and mechanical properties of carbon fiber composite materials, the use of carbon f...

Abstract
The invention relates to a forming mold and a forming method of a carbon fiber composite plastic product, wherein the forming mold mainly includes a fixed mold assembly, a movable mold assembly, a pouring system and an ejection mechanism, and the fixed mold assembly and the movable mold assembly A molding cavity for molding carbon fiber composite plastic products is formed between the mold components; the fixed mold component includes a fixed mold bottom plate and a runner plate connected in sequence; the pouring system includes: a sprue bushing, the sprue The sleeve is fixed on the bottom plate of the fixed mold; a plurality of main runners and a plurality of sub-runners; wherein the plurality of main runners and the plurality of sub-runners are respectively located on the runner plate; each The main runners are respectively communicated with the sprue sleeve; the multiple secondary runners are respectively connected to one of the main runners; a plurality of gates are connected with the molding cavity; wherein, each of the secondary runners The channels are respectively communicated with a gate, and the sprue sleeve is also communicated with a gate.
Description
technical field [0001] The invention relates to the field of preparation and processing of carbon fiber composite materials, in particular to a molding die and a molding method of carbon fiber composite plastic products. Background technique [0002] At present, most plastic products are produced by injection molding using polycarbonate (Polycarbonate, PC) and polyacrylonitrile (Acrylonitrile Butadiene Styrene, ABS) synthetic engineering plastics as raw materials. However, the plastic products made of this kind of material are thicker, heavier, prone to deformation after molding, and have poor electromagnetic shielding properties. Especially when used in the production of modern plastic products, it often cannot meet the needs of consumers for plastic products. [0003] Therefore, it is urgent to provide a forming mold and a forming method capable of forming lighter, thinner, stronger and better electromagnetic shielding plastic products, so as to obtain better plastic prod...
