Vacuum mold-closing die for molding of special-shaped composite components

Abstract

The invention provides a vacuum mold-closing die for the molding of special-shaped composite components, by which the sealing problem of several connected sections of a complex structure is solved, the fitness of a fiber reinforcement body and the mold can be observed in the process of die assembling, and the effects that products are not deformed after being molded, not stressed in the process of demoulding and high in surface smoothness, and have no defects of no poor adhesive, rich resin and the like are ensured. The die comprises a left side plate, a cover plate, a right side plate, a front side plate, a rear side plate, an upper left die, a lower left die, a front cushion block, an upper right die, a lower left die, a rear cushion block, an O-shaped sealing ring, a middle shaft and a base, wherein a parting surface is of a left-and-right halved structure and divided into the upper left die, the lower left die, the upper right die and the lower right die; the base, the upper left die, the lower left die, the upper right die, the lower right die, the middle shaft and the cover plate are combined together so as to form a mold cavity, and the upper left die, the lower left die, the upper right die and the lower right die are extruded and sealed by the front, rear, left and right side plates. In the process of demoulding the structure, a product is not stressed and deformed.

Description

technical field [0001] The invention relates to a special-shaped composite material forming mold suitable for vacuum injection, in particular to a vacuum closed mold for forming special-shaped composite material components. Background technique [0002] The special-shaped composite material component is a rotary structure with extended wings, which acts near the flame vent and must meet the scour requirements in high-temperature environments. The fiber reinforcement needs to be impregnated and cured by vacuum injection of resin. The product requires high resin content, and the phenomenon of poor glue and rich resin should not appear, and the surface has no defects. To ensure the molding size and precision of the product, directly form a product with a smooth surface, with sufficient rigidity and strength, to ensure that there is no damage during mold closing, mold opening and injection, and that the product is not deformed. In the mold design, comprehensive Considering vari...
