Abstract

The invention provides a molding method and a mold used in resin transfer molding technology of a cable rectifying cover. The molding method and the mold are used for integrally molding sheet metal parts and the heat-proof layer. The molding method comprises the steps of: mold treatment, precast of sheet metal parts, laying of fiber reinforcement, mold assembly, pipe connection, airtight inspection, resin heating, mold heating, pressure injection of resin, curing and demolding. The mold comprises a lower pressure plate (1), a male die (2), a female die (3), an upper pressure plate (4), seal rings (5), a resin impregnating connector (6), a small nut (7), a screw rod (8), a big nut (9) and a resin discharging connector (10), wherein the cavities of the female die (3) and the male die (2) are matched with the cable rectifying cover in shape; and the surfaces of the male die (2), the female die (3) and the lower pressure plate (1) contacted with the male die (2) are respectively provided with a rectangular seal groove used for installing the seal ring (5). By utilizing the molding method and the mold disclosed by the invention, the molding efficiency is high, and the quality is stable.

Description

technical field [0001] The invention relates to a process molding method and mold of a fairing, in particular, the invention relates to a resin molding transfer process forming method and a mold of a cable fairing. Background technique [0002] In the field of aerospace and some special operations, due to the high temperature requirements of the working environment of the equipment, it is necessary to install a fairing on the outside of the leaking cable for heat insulation, because the cable fairing must meet certain requirements for compression resistance, deformation resistance and subsequent processing. , so if figure 1 The general cable fairing shown is obtained by fixedly connecting the lower metal sheet part b and the upper heat-proof layer a, and the heat-proof layer is formed by a fiber reinforced body through a resin molding transfer method. [0003] There are two general methods for forming cable fairings. One forming method is to directly transfer the fiber rein...
