Problems solved by technology

[0002] Existing automobile wheel hubs use aluminum alloy casting molds to form blanks, and then carry out mechanical processing. Due to the large size and uneven wall thickness of automobile wheel hub products, air holes are often found in the cast blanks after processing, and the density is loose. , the use strength and sealing effect of the product cannot be reached, the light one can be used after remediation, and the serious one can only be used as waste and re-melted, which increases the cost of the product and reduces the production efficiency
Moreover, because many grooves and mounting holes also need subsequent processing, the production process and production time of the rim are increased.

Embodiment 1

[0035] The present invention is a kind of mold structure that is used for solidification molding of carbon fiber automobile wheel hub blank product, and it comprises upper mandrel 1, lower mandrel 2 and two side molds 3 of the outer ring 81 shape of solidification molding carbon fiber automobile wheel hub blank product, such as figure 2 shown;

[0036] The upper mandrel 1 is fixed with an inner air bag 4 in the shape of the inner cavity 82 of the solidified and formed wheel hub. The inner air bag 4 is made of silica gel. The inner cavity 82 of the blank, the inner air bag 4 and the upper core mold 1 are provided with a flange 404, and the inner air bag 4 locks the flange 404 on the upper mandrel 1 through the pressure plate 6. When opening and closing the mold The inner air bag 4 can move together with the upper mandrel 1; the upper mandrel 1 is also provided with two steam passages, one is a steam passage 101 for heating and pressurizing the inner air bag 4, and the other is...

Embodiment 2

[0047] Embodiment two: if Image 6 , Figure 7 Shown, differs from embodiment one mold structure in that:

[0048] An outer air bag 5 is also sandwiched between the hub blank 8, the upper core mold pressing plate 6, and the inner air bag 4; the outer air bag 5 is made of silica gel, and a flange 501 is provided on the mating surface of it and the pressing plate 6, and at the same time The splint 6 is provided with a concave annular surface 601 that matches the shape of the flange 501 and can accommodate the flange 501 at the corresponding position. When the mold is closed, the outer air bag 5 is sandwiched by the inner air bag 4, the pressure plate 6 and the wheel hub through the flange 501. Between the blanks 8, the shape of the inner 4 and outer 5 airbags is consistent with the shape of the inner cavity of the hub, and the size of the inner airbag 4 is slightly smaller than the size of the outer airbag 5, so that when the mold is closed, the inner airbag 4 will not be in th...

Abstract

The invention discloses a mold structure for curing and forming carbon fiber automobile rim blank products and a method for manufacturing products by the mold. The product intensity and integrality of the carbon fiber automobile rims manufactured by the mold and the method are good, and because full-carbon-fiber automobile rims are adopted, the product quality and level are improved. Compared with aluminum rims, the full-carbon-fiber automobile rims can be reduced by 60-80% in weight, save energy and reduce consumption, and reduce the driving cost. The full-carbon-fiber automobile rims do not need product processing, are formed integrally, reduce the production process, and improve the product intensity.

Description

Technical field [0001] The invention relates to a mold structure of an automobile wheel hub formed entirely of carbon fibers and a method for making products with the mold. Background technique [0002] Existing automobile wheel hubs use aluminum alloy casting molds to form blanks, and then carry out mechanical processing. Due to the large size and uneven wall thickness of automobile wheel hub products, air holes are often found in the cast blanks after processing, and the density is loose. , the use strength and sealing effect of the product cannot be reached, and the light one can be used after remediation, and the serious one can only be used as waste and returned to the furnace, which increases the cost of the product and reduces the production efficiency. And because many grooves and mounting holes also need follow-up processing, the rim production process and production time are increased. [0003] As we all know, carbon fiber is 1 / 4 the weight of steel, but its stren...
