Problems solved by technology

[0002] With the development of unmanned aerial vehicle technology, the design of unmanned structural aircraft puts forward higher requirements for its high performance and low weight, while composite materials have low density, high specific strength, high specific modulus, good high and low temperature resistance, and Corrosion and other advantages, so in the structural design of the UAV, its components are designed as a composite material structure, such as the main load-bearing part of the UAV's wing is designed as a carbon fiber composite part with a multi-wall box structure, and many The structural composite parts of the wall box section are faced with the difficulty of demoulding during production and manufacture. Since the part tightly wraps the mandrel, the contact area is large, and the adhesion between the part and the mandrel is very strong. The existing method is not good. for demoulding

Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] Such as Figure 1-4 As shown, a demoulding tooling for multi-wall box-section structural composite parts. The tooling includes five parts: a bottom frame 1, a pressure plate assembly 2, a stopper assembly 3, an ejection mechanism 4, and a positioning connector.

[0039] The pressing plate assembly is composed of an upper pressing plate 2-1, a lower pressing plate 2-2, and a silica gel sheet. The upper and lower pressing plates are made of wood, and its profile is consistent with the shape of the workpiece.

[0040] The ejector mechanism 4 is composed of T-shaped slot 4-2, T-shaped block 4-1, screw rod 4-3, nut 4-4, and C-shaped top block 4-5. The T-shaped block can slide along the T-shaped slot, and the nut is connected It can be rotated on the T-shaped block, and the position and direction of the screw rod can be adjusted by moving the T-shaped block...

Abstract

The invention belongs to the field of material preparation, and particularly relates to a demolding tool and demolding method for a multi-wall box section structure composite part. The demolding toolis used for demolding a plurality of core molds of the multi-wall box section structure composite part and comprises a pressing plate assembly, an ejection mechanism and a stop block assembly, the pressing plate assembly comprises an upper pressing plate and a lower pressing plate, a molded surface formed between the upper pressing plate and the lower pressing plate is consistent with the appearance of the part; the ejection mechanism is mounted on one sides of the small ends of the core molds and used for loosening the core molds to be removed; and the stop block assembly is detachable, is mounted at the large end of the adjacent core molds of the core molds to be removed, and is used for stopping the movement of the adjacent core molds of the core molds to be removed; and the demolding method for the multi-wall box section structure composite part comprises the following step that the multi-wall box section structure composite part with the core molds is placed on a tool, the part ispressed through the pressing plate assembly, the stop block assembly is installed at the large ends of the core molds, and the core molds in the part is ejected out in order through the ejection mechanism. By means of the demolding tool and the formulated demolding method for the multi-wall box section structure composite part, demolding work of the multi-wall box section structure composite partcan be conveniently, reliably and safely achieved.
