Description

Transition core mold for pneumatic exterior composite tooling of unmanned aerial vehicle

Technical Field

The utility model relates to the field of unmanned aerial vehicle moulds, in particular to a transition core mould for an unmanned aerial vehicle pneumatic appearance composite material tool.

Background

As is well known, with the continuous development of composite material technology, the excellent characteristics of the composite material are gradually recognized by people, the application range of the composite material is rapidly expanded, and the composite material is more and more widely applied to aerospace. In the manufacturing and forming process of the composite material, a metal forming die is usually adopted, and the dimensional accuracy of the composite material product after curing and forming is lower due to the larger difference between the expansion coefficients of the metal and the composite material.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a transition core mold for an unmanned aerial vehicle pneumatic appearance composite material tool, which reduces deformation caused by solidification.

The technical scheme adopted for solving the technical problems is as follows: a transition mandrel for unmanned aerial vehicle pneumatic exterior combined material frock is equipped with polymer composite's transition core die body, characterized by, transition core die body is concave structure, the profile processing of the interior standing edge of transition core die body has the inclination, the profile outside processing of the outer standing edge of transition mandrel has temperature measurement hole, target hole, install the target mark point in the target hole, the profile upper portion processing of the outer standing edge of transition mandrel has rings, two fork truck holes are installed to one side of the profile of the outer standing edge of transition mandrel, processing has ejecting hole on the transition mandrel body bottom surface, the inboard processing of ejecting hole has the recess of size greater than ejecting hole cross section, the loose piece has in the recess is established.

The utility model has the beneficial effects that the tooling of the composite material is used for curing the composite material product, so that the dimensional accuracy of the composite material product can be improved, and the deformation caused by curing can be reduced.

Drawings

The utility model will be further described with reference to the drawings and examples.

FIG. 1 is a schematic diagram of the structure of the present utility model.

Fig. 2 is a structural view of the ejection hole.

In the figure, a transitional core die body 1, an inclined angle 2, a temperature measuring hole 3, a lifting ring 4, a forklift hole 5, an ejection hole 6, a movable block 7 and a groove 8.

Detailed Description

In the figure, the transition core die body 1 provided with the molecular composite material is in a concave structure, the profile of the inner vertical edge of the transition core die body 1 is processed with the inclined angle 2 for demolding, the inclined angle 2 can be better demolded, the outside of the profile of the outer vertical edge of the transition core die body 1 is processed with the temperature measuring hole 3 and the target hole, the target point is arranged in the target hole and used for laser projection positioning, the paving precision of the prepreg of the pneumatic exterior composite material tool in the paving process can be improved, the temperature measuring hole 3 is mainly used for monitoring the temperature and the heating rate of a mold, and the curing and pressurizing parameters can be better controlled. The upper portion of the profile of the outer vertical edge of the transition core die body 1 is provided with a hanging ring 4, the hanging ring 4 is convenient for carrying and lifting the die, the bolt hole is convenient for installing and detaching the loose piece, and the forklift hole is convenient for tool transportation. Two forklift holes 5 are arranged on one side of the profile of the outer vertical edge of the transition core die body 1, a cylindrical ejection hole 6 is machined in the bottom surface of the transition core die body 1, a groove 8 with the size larger than the cross section of the ejection hole is machined in the inner side of the ejection hole 6, a movable block 7 is arranged in the groove 8, the movable block 7 is matched with the groove 8 in the inner side of the ejection hole 6, and the movable block 7 is placed in the groove 8 of the ejection hole 6 when the transition core die is used for solving the problem that a manufactured product is difficult to demould.
