Description

Technical Field

[0001] The utility model relates to the technical field of aviation composite material production, in particular to an aviation composite material forming die. Background Art

[0002] Since the 1970s, the use of composite materials in the aviation industry has been increasing. Traditional materials for manufacturing aircraft structures include aluminum, steel and titanium. The main benefits of composite materials are reduced weight and simpler assembly. Performance advantages and reduced aircraft structural weight are the main driving forces for the development of composite materials for military aircraft. Although commercial aircraft are increasingly paying attention to fuel economy, the main driving force for the development of composite materials is to continuously reduce production and maintenance costs. Composite materials are also used to replace metal parts on old aircraft. In order to improve the production efficiency of aviation composite materials, a molding mold is needed, but the existing molding molds still have the following shortcomings:

[0003] For example, the utility model with application number 202021782358.1 discloses an injection mold for molding aviation composite materials. The utility model moves the movable mold upward and contacts the adjusting mold, so that the position of the cavity is convenient for the injection of molten material. At the same time, when the hydraulic cylinder is in the lifted state, the movable mold continues to be driven upward, thereby driving the adjusting mold to squeeze the fixed mold upward, so that the cavity and the gap are squeezed, and the molten material is squeezed tightly for easy molding. The fixed mold and the adjusting mold are easily aligned by using limit columns and limit holes. The fixed block slides on the fixed column to facilitate the limiting of the adjusting mold and the fixed mold. The elastic change of the spring facilitates the resetting of the adjusting mold. However, similar to the comparative documents of the above-mentioned application, when the existing molding molds are used, since most molding molds do not have the performance of rapid cooling, the demolding time of the molding mold is prolonged during use, resulting in the problem of reduced practicality and reduced use efficiency of the molding mold.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an aviation composite material forming mold is proposed. Utility Model Content
