Forming mould and forming method of notebook face shell

Abstract

The invention discloses a forming mould and forming method of a notebook face shell. The mould comprises a fixed mould part and a movable mould part. The fixed mould part comprises a fixed mould face plate (1), square iron (2), an ejector pin bottom plate (3), an ejector pin face plate (4), a fixed mould plate (5), a fixed mould core (6) and a hot sprue (18). The movable mould part comprises a movable mould base plate (9), a movable mould plate (8) and a movable mould core (7). A mould cavity (71) which is the same as the face shell (100) in inner shape and a mould cavity (71) which is the same as the face shell (100) in outer shape are formed between the fixed mould core (6) and the movable mould core (7). A fixed mould core insert (19) is arranged on the fixed mould core (6). A casting system communicates with the mould cavities (71) through the fixed mould core insert (19). After mould closing, mould filling, compaction, pressure maintaining and cooling are conducted, a reverse buckling part and a glue inlet and gate part of a product are pushed out through a push-out system, and finally, the product is taken out. A carbon fiber composite material is used as a face shell material of the reverse mould, and the manufactured face shell product is low in mass, small in thickness, high in strength, good in electromagnetic shielding property, good in surface quality and good in performance.

Description

technical field [0001] The invention relates to a molding die and a molding method, in particular to an injection molding mold and a molding method of a notebook cover made of carbon fiber composite material. Background technique [0002] At present, digital 3C products such as notebook computers and tablet computers are developing in the direction of "lighter and thinner", and consumers have higher and higher requirements for the portability of notebook computers. At present, the general notebook computer shell adopts traditional engineering plastics such as PC+ABS, but the thickness of the notebook computer shell products produced with this material is generally 2-3mm, the weight is not ideal, and it is difficult to achieve ultra-thin design. At present, super notebooks are gradually adopting aluminum-magnesium alloy cover to achieve ultra-thin design. The thickness of notebook computer cover products produced with this material is generally 1-2mm, but there are problems s...

AI Technical Summary

Problems solved by technology

[0004] Using carbon fiber composite materials as injection molding raw materials can produce plastic products that meet the above requirements; however, due to the poor fluidity of carbon fiber composite materials, the products produced often cannot meet the quality requirements; The surface effect of carbon fiber plastic products is not good, and subsequent surface treatments such as spraying UV oil and vapor deposition are often required, which increases production costs. Therefore, this material is currently less used in injection molding of plastic products.
