Embodiment Construction

[0025] The invention provides a kind of aircraft fairing mould, and mold comprises main mold body 1 and sub-mould body 2; The mating surface flanging 3 of body is longer than the mating surface flanging 4 of sub-mould body, and the mating surface flanging of main mold body and the mating surface flanging of sub-mould body form step shape after the mold closing, and main mold body The stepped surface 5 of the main mold body is used to fix the vacuum bag 6, and there are bolt through holes 7 and pin through holes 8 on the flange of the clamping surface of the sub-mould body, corresponding to the bolt through holes 8 on the flange of the clamping surface of the main mold body. The positions of the hole and the pin through hole are buried with threaded sleeve 9 and bushing 10 respectively.

[0026] The using method of mold of the present invention, its specific process is as follows:

[0027] Step 1. Mold closing

[0028] Position the sub-model body and the main model body of th...

Abstract

The invention relates to an aircraft fairing mold and a using method. The mold comprises a main mold body and a sub-mold body; a threaded sleeve and a lining sleeve are embedded into the mold partingsurface of the main mold body, and a lining sleeve is embedded into the mold parting surface of the sub-mold body; the sub-mold body is fixed to the main mold body through a pin and a bolt; and a vacuum bag is adhered to a sealing zone of the main mold body, the sub-mold body is wrapped in the vacuum bag, the mold parting surface is also wrapped in the vacuum bag, and therefore a sealing strip isnot needed. The main mold body is fixed to a supporting frame, the sub-mold body needs to be often dismounted and mounted, therefore, the sub-mold body and the main mold body are both made of a composite material, the mold weight is greatly decreased, and operation is convenient.

Description

technical field [0001] The invention belongs to the field of composite material molding dies. Background technique [0002] The solidification and molding of composite parts and components requires the help of a mold. The mold should preferably be a complete overall structure with overall vacuum tightness; ) cannot be successfully and completely removed from the mold, it is necessary to consider dividing the mold into several modules, but the complete vacuum degree of the mold must be guaranteed. The past practice is to install a sealing strip in the parting surface. Made of silicone rubber, when the mold is heated, the silicone rubber will expand and seal the parting surface. When wrapping the mold with a vacuum-sealed bag, stick the vacuum bag to the end of the silicone rubber sealing strip with a putty strip (the end that exposes the parting surface, see figure 2 and image 3 ); In this way, the mold, silicone rubber sealing strip, putty strip, and vacuum bag form a se...
