Method for manufacturing vacuum mould closing of false ogive

Abstract

The invention provides a vacuum mold closing die and the application thereof in a fairing vacuum mold closing manufacturing method. The vacuum mold closing die comprises a compound lower die, wherein, a compound lower end upper module is arranged on the upper side of the compound lower die; a dynamic seal ring is arranged along the circumference of the upper side of the upper module of the compound lower die; an aerofoil seal ring is arranged on one side of the dynamic seal ring; a semi-rigid composite material upper die is arranged on the compound lower die and the upper module thereof; a glue storing device is in the lower position of the semi-rigid composite material upper die; a glue outlet is formed at the upper end of the glue storing device; a glue injecting port is formed in the higher position of the semi-rigid composite material upper die; a flow channel is arranged at the lower end of the glue injecting port; and a vacuum orifice is formed on the upper side of the semi-rigid composite material upper die. The vacuum mold closing die can be applied in the fairing vacuum mold closing manufacturing method. The vacuum mold closing die and the application thereof in the fairing vacuum mold closing manufacturing method has the advantages that the investment and the manufacturing cost are low; the production efficiency is high; almost no industrial refuse is generated; the performance of a manufactured product is excellent; and the working environment is good.

Description

technical field [0001] The invention relates to a vacuum closed mold manufacturing method for a fairing, and belongs to the technical field of a vacuum closed mold manufacturing method for a fairing. Background technique [0002] There are many kinds of vacuum injection molding technologies for composite materials, such as vacuum resin introduction process, the product layer is placed on the lower mold, and then the release cloth, resin diversion medium, diversion tube and vacuum sealing bag are laid to form a sealed system , under a certain degree of vacuum, the resin is introduced into the laminate in the mold cavity. The product performance and working environment of this technology are good, but its vacuum-sealed bag, release cloth, resin diversion medium and diversion tube are basically disposable, resulting in a large amount of industrial waste. Another vacuum injection molding technology is resin transfer molding technology, which uses a pair of closed molds, lays th...

AI Technical Summary

Problems solved by technology

However, the mold manufacturing cost of this technology is expensive, and when the product is large, the mold weight will be large, and a special device for opening and closing the mold is required, and the investment and manufacturing costs are greater

And when the product has a chamfered structure, it is difficult to use the molding process because it cannot be released from the mold
