Embodiment 1

[0021] As shown in Figure 1, it is a side sectional view of a vacuum closed mold provided by the present invention, consisting of an airfoil sealing ring 1, a circular sealing ring 2, a dynamic sealing ring 4, a composite lower mold upper module 5, and a semi-rigid composite material The upper mold 8, the composite lower mold 9, the glue storage device 10, the vacuum port 11, the glue injection port 12, the glue outlet 13 and the flow channel 14 are composed.

[0022] A rubber storage device 10 is provided at the lower part of the semi-rigid composite material upper mold 8, and a glue outlet 13 is provided at the upper end of the rubber storage device 10, and at the height of the semi-rigid composite material upper mold 8 and the upper module 5 of the composite lower mold There is a glue injection port 12, a flow channel 14 is provided at the lower end of the glue injection port 12, a dynamic sealing ring 4 is provided on the edge of the bottom of the semi-rigid composite upper...

Embodiment 2

[0031] The difference between this embodiment and embodiment 1 is that in step 4, an injection machine is used to inject the resin, and a positive pressure of 10KPa is applied to the resin. Other structures and steps are the same as in Example 1.

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...
