Demolding tool and demolding method for multi-wall box section structure composite part

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.

Description

technical field [0001] The invention belongs to the field of material preparation, and in particular relates to a demoulding tool and a demoulding method for a multi-wall box segment structural composite part. Background technique [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 wra...
