Background
The design requirements of a new generation of fighter plane mainly include indexes such as stealth performance, supersonic cruise, super maneuverability, reliability and maintainability, and the supersonic cruise and super maneuverability need an advanced high thrust-weight ratio engine and reduction of the structural weight coefficient of the airplane, so that the application proportion of the composite material on the airplane needs to be improved; the stealth capability is the most important index for forming the overall fighting capacity, and the level of the stealth capability directly influences the overall fighting capacity in the system confrontation. In order to meet the performance requirement of ultrahigh stealth of an airplane, the shape of an engine air inlet is stealthed, so that the shape of the air inlet is very complex and is usually a complex-profile non-revolving body with large-area negative curvature.
At present, all aircraft air inlets are made of metal materials, and few examples of air inlets made of composite materials are provided, one of the main reasons is that the design and manufacture of a die can not meet the molding requirements of the integral air inlet made of the composite materials. The shape of an air inlet of a common airplane is complex, and the design difficulty of an air inlet mould is increased by solving the problem that the mould is demolded and drawn out from a part.
At present, a combined die is generally adopted for molding a complex-surface non-revolving body air inlet with large-area negative curvature for the whole composite material air inlet, and positioning pins and bolts are adopted for positioning and connecting all the blocks of the combined die. Because the number of the mold blocks is large, the number of the positioning pins and the bolts is also large, and the block mold is complicated and even can not be smoothly removed from the composite material cylinder when being removed from the composite material cylinder after the mold is assembled and cured.

The invention aims to provide a positioning and connecting integrated device for a combined die, which simplifies the assembly of the combined die and ensures that parts are quickly and conveniently removed after solidification. The method is mainly used for the integrated molding of complex-profile non-revolving bodies such as S-shaped integrated air inlet channels made of composite materials.
The technical solution of the invention is as follows: the device comprises an upper positioning block, a lower positioning block and a die support, wherein the upper positioning block is a C-shaped metal module with an inner profile provided with a chamfer, the lower positioning block is a T-shaped metal module with an outer profile provided with a chamfer, the chamfer of the upper positioning block and the chamfer of the lower positioning block are in a matching relation, the inner profile of the upper positioning block is matched with the outer profile of the lower positioning block, a groove corresponding to the size and the shape of the lower positioning block is formed in the surface of the die support, the lower positioning block is arranged in the groove through a round rod, so that the lower positioning block rotates around the round rod between 0 degree and 90 degrees, when the device is applied to a combined, the upper positioning block is fixed on each block of the combined die, a groove is formed in the position, corresponding to the upper positioning block, of the die support, a lower positioning block is installed in each groove through a round rod, and the lower positioning block can be accurately embedded into the inner molded surface of the upper positioning block.
The connection mode between the upper positioning block and the sub-blocks of the combined die is welding.
The block mould for the integral composite material molding is at least two.
The invention has the advantages and beneficial effects that: according to the invention, the positioning and connection between the combined die blocks and the die bracket are realized by adopting the C-shaped lower positioning block and the T-shaped upper positioning block with the chamfers, the die assembling process is simplified, and the combined die blocks can be conveniently separated from the inside of a workpiece after the composite material is cured. The problem that the mold is demolded and drawn out from a part needs to be solved, a split combined mold needs to be adopted, and the positioning and connecting technology between the split combined molds is the key point for realizing the quick assembly of the mold and facilitating the disassembly and the removal of the mold. The invention mainly solves the problem of positioning and connecting of the block dies for forming the complex-profile non-revolving bodies such as the S-shaped air inlet channel and the like made of the integral composite material.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings. As shown in fig. 1, 2, 3, 4, 5, 6 and 7: the device comprises an upper positioning block 1, a lower positioning block 2 and a die support 3, wherein the upper positioning block is a C-shaped metal module with an inner profile provided with a chamfer, the lower positioning block is a T-shaped metal module with an outer profile provided with a chamfer, the chamfer of the upper positioning block and the chamfer of the lower positioning block are in a matching relation, the inner profile of the upper positioning block is matched with the outer profile of the lower positioning block, the surface of the die support is provided with a groove corresponding to the size and the shape of the lower positioning block, the lower positioning block is arranged in the groove through the positioning block and a round rod 4, so that the lower positioning block rotates around the round rod at 0-90 degrees, when the device is applied to a, the upper positioning blocks are fixed on the sub-blocks of the combined die, a groove is formed in each position, corresponding to the upper positioning block, of the die support, a lower positioning block is installed in each groove through the positioning blocks and the round rods, and the lower positioning blocks can be accurately embedded into the inner molded surfaces of the upper positioning blocks (figure 5). When the die is assembled, the lower positioning block and the die support are positioned at 90 degrees (figure 6) and are matched in the upper positioning block, so that the positioning and the connection between the combined die blocks and the die support are realized; when the mold is demolded, the mold support is pulled, the lower positioning block is separated from the upper positioning block, then the lower positioning block and the mold support are positioned at 0-degree position (shown in figure 7) and embedded into the groove on the surface of the mold support until the mold support is removed, and finally the partitioned molds are removed one by one.
