Novel continuous molding mould for ultrathin component

Abstract

The invention provides a novel continuous molding mould for an ultrathin component. The novel continuous molding mould comprises a left baffle 1, a front baffle 2, a male mould 3, a flexible mould 4, a right baffle 5, a female mould 6 and a rear baffle 7, wherein the male mould 3 has a convex curved surface; the female mould 6 has a concave curved surface at a position corresponding to the convex curved surface; the circular arc radius of the convex curved surface is equal to that of the concave curved surface; the male mould 3 is covered with the flexible mould 4; the left baffle 1, the front baffle 2, the rear baffle 7 and the right baffle 5 are respectively in screw joint to the periphery of the male mould 3 and are used for blocking the flexible mould 4. According to the novel continuous molding mould, the flexible mould and a fixing device of the flexible mould are additionally arranged, so that a composite material component for a large ultrathin non-equal-thickness complex satellite can be prepared with high accuracy; the product is excellent in surface quality, high in accuracy of the molded surface and excellent in performance; the problem of molding of the composite material component for the large ultrathin non-equal-thickness complex satellite can be solved; the problems of poor appearance quality, high porosity and poor accuracy of the molded surface caused by uneven pressure distribution of a metal mould due to the non-equal thickness of the product can be solved.

Description

technical field [0001] The invention belongs to the field of composite material molding, and in particular relates to a novel continuous molding die for ultra-thin components. Background technique [0002] Due to the limitation of the effective space load of the launcher, the deployable space structure plays an important role in the traditional aerospace field. At present, an obvious trend is that deployable space structures will be used in future space structure applications, such as instrument support rods, antennas, reflectors, solar sails, and large solar systems. The expandable composite material components of the expandable spatial structure require the characteristics of large-scale, ultra-thin, and non-uniform thickness sections. Currently, the forming molds used in the forming process of components are all-metal structures. Due to the ultra-thin and non-uniform thickness characteristics of the components, the precision of the molding surface of the mold is high, an...
