Preform reinforcing plate universal vacuum mold closing mold

Abstract

The invention provides a universal vacuum mold closing mold for forming a preform reinforcing plate. The universal vacuum mold closing mold comprises an upper mold, a lower mold, a left partition plate, a right partition plate, a front partition plate, a rear partition plate, positioning screws, demoulding screws and O-shaped sealing rings. By replacing the partition plates of different thicknesses, preform reinforcing plate composite materials of different thicknesses are formed. A parting surface adopts an upper, middle and lower halved structure, so that the sealing problem of a plurality of sections of a complicated structure is solved, the conjoint ratio of a preform reinforcement and the mold can be observed in the mold assembly process, it is ensured that a product does not deform after molding, no force is applied in the demolding process, the surface smoothness is high, and no defects such as poor gel and rich resin are achieved; and a plate mold is designed to be in a convexshape, on the one hand, the thickness of a plate is controlled, and on the other hand, the rigidity of the mold is increased; and more importantly, the compactness of impregnation of a preform is improved, and the percentage composition of fiber is increased.

Description

technical field [0001] The invention relates to a positioning device for prefabricated reinforcement boards suitable for vacuum injection, in particular to a vacuum closed mold for forming prefabricated reinforced boards. Background technique [0002] The prefabricated body reinforced composite material must meet high specific strength and specific modulus. The reinforced part of the prefabricated body is integrally braided and molded, and the prefabricated body is impregnated and cured by vacuum injection resin. The product requires high resin content and no poor glue. , Rich resin phenomenon, no defects on the surface. In the process of product molding, the key technology is the design of the mold, which directly affects the dimensional accuracy of the product, the resin filling path, and the mold will ensure the performance and quality of the product. If there are some defects in the mold design (such as strength, sealing, etc.), the adhesion between the resin and the fi...
