A manufacturing method of a continuous special-shaped component soft mold comprises the following steps:
(1) extruding the resin in a multi-layer co-extrusion heating extrusion mode;
(2) customizing a special die, wherein the die is customized according to the shape of a product, and the die is designed in a block combination manner;
(3) the molten resin is shaped after passing through the customized die, and ceaseless overturning is carried out in the forming process according to die block combination, so that different shapes can be shaped in a block mode, continuous extrusion is realized, and a continuous hollow special-shaped component soft die can be integrally manufactured.
The invention has the beneficial effects that: compared with the prior art, the continuous special-shaped member soft mold and the manufacturing method thereof adopt the special soft mold and utilize the special mold to form the hollow special-shaped member soft mold, air pressure is filled during use to form an air bag package, the air bag package is convenient to lay and stick, the air bag package is decompressed and extracted after use, and the product structural member can be applied to laying and sticking large-sized and long-length carbon fiber product prepreg cloth.
The specific implementation mode is as follows:
the continuous special-shaped member soft mold adopts a three-layer structure, wherein the inner layer is polyamide 6 or polyamide 66, the middle layer is a microcellular foaming expansion elastomer, and the outer layer is perfluoroethylene propylene or ethylene-tetrafluoroethylene copolymer.
A manufacturing method of a continuous special-shaped component soft mold comprises the following steps:
(1) extruding the resin in a multi-layer co-extrusion heating extrusion mode;
(2) customizing a special die, wherein the die is customized according to the shape of a product, and the die is designed in a block combination manner;
(3) the molten resin is shaped after passing through the customized die, and ceaseless overturning is carried out in the forming process according to die block combination, so that different shapes can be shaped in a block mode, continuous extrusion is realized, and a continuous hollow special-shaped component soft die can be integrally manufactured.
The performance of the continuous special-shaped component soft mold is compared with that of the rubber soft mold in the prior art as follows:
in summary, compared with the prior art, the continuous special-shaped component soft mold and the manufacturing method thereof adopt the special soft mold and utilize the special mold to form the hollow special-shaped component soft mold, air pressure is filled during use to form the air bag device, the air bag device is convenient to lay and stick, the air bag device is decompressed and extracted after use, and the product structural member can be applied to laying and sticking large-sized long carbon fiber product prepreg cloth.
The present invention has been described in accordance with embodiments thereof with the understanding that the present invention is not limited thereto but rather it is to be understood that variations and/or modifications may be made by those skilled in the art without departing from the scope of the invention as defined by the appended claims, and any such modifications, equivalents and the like as fall within the true spirit and scope of the invention.
