Abstract

The invention belongs to composite material blade forming techniques, and in particular to one kind is used for the molding iron clad elastic mould manufacturing method of blade leading edge.In the forming technique of composite material blade, because blade iron clad is especially high to shape dimension precision requirement, the country is temporarily without related die manufacturing experience.The present invention is used for the molding iron clad elastic mould manufacturing method of blade leading edge, preparation and the consistent upper mold of blade leading edge size；The paving rubber size in upper mold is formed using autoclave pressurized, heated, forms interior elastomer；Epoxy resin and filler are filled in lower die；Upper die and lower die are molded, curing and demolding obtains the elastic mould being made of interior elastomer and outer filled layer, obtains iron clad elastic mould in the forming surface iron clad of the elastic mould.By elastomer pressurization, greatly the pressurization of protection iron clad is uniform, is not easy to spring back, while can improve iron clad molding qualification rate with traditional hard pressuring method than protecting iron clad piece surface not have crush injury.

Description

One kind being used for the molding iron clad elastic mould manufacturing method of blade leading edge
Technical field
The invention belongs to composite material blade forming techniques, and in particular to one kind is for the molding iron clad elasticity of blade leading edge Mould manufacturing method.
Background technique
In the forming technique of composite material blade, because blade iron clad is especially high to shape dimension precision requirement, domestic temporary nothing Related die manufacturing experience.
Summary of the invention
The present invention breaks through the processing of mold Hookean region, proposes a kind of for the molding iron clad elasticity of blade leading edge Mould manufacturing method.
One kind being used for the molding iron clad elastic mould manufacturing method of blade leading edge, method includes the following steps:
(1) preparation and the consistent upper mold of blade leading edge size；
(2) the paving rubber size in upper mold is formed using autoclave pressurized, heated, forms interior elastomer；
(3) epoxy resin and filler are filled in lower die；
(4) upper die and lower die are molded, curing and demolding obtains the springform being made of interior elastomer and outer filled layer Tool, obtains iron clad elastic mould in the forming surface iron clad of the elastic mould.
The paving thickness 18-22mm of the rubber size.
Production vacuum bag is put into autoclave, and 150 DEG C of high temperature, pressure 0.4mpa vulcanization are more than half an hour.
The upper mold is formpiston, and the lower die is former.
The shore hardness of the interior elastomer is in 45-55.
Before paving rubber size, coking softening is carried out to rubber size using rubber mixing machine.
The utility model has the advantages that the invention is pressurizeed greatly by elastomer, the pressurization of protection iron clad is uniform, is not easy to spring back, while can With traditional hard pressuring method than protecting iron clad piece surface not have crush injury, improves iron clad and form qualification rate.
Detailed description of the invention
Fig. 1 is the combination schematic diagram of upper and lower mould of the invention.
