Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an aircraft air inlet mold. Background Art

[0002] The air intake of some aircraft is on the top of the aircraft back. When the air passes through the lip of the air intake, it is divided. Part of the airflow enters the front end of the air intake, and part flows along the skin outside the lip. To ensure the air intake efficiency, the shape of the lip is usually more complex. At the same time, the connection with the skin above or around the lip must also be considered. The conventional design is that the lip is separated from the air intake. The lip is made of metal and the air intake is made of composite materials. The metal lip and the air intake are connected by a glue-riveted process. There are problems such as difficulty in connecting fasteners in local areas and the risk of fasteners entering the engine. Utility Model Content

[0003] In response to the deficiencies in the prior art, the utility model provides an integrated molding die for the air intake duct and the lip, which uses a paving process to complete the integrated molding of the lip and the air intake duct, avoiding the risk of fasteners entering the engine, while reducing the number of parts and lightening the part quality.

[0004] The purpose of the present utility model is achieved as follows: an air intake duct and lip integrated molding mold, including an air intake duct paving mold, the front end of the air intake duct paving mold is connected to a front baffle, the rear end of the air intake duct paving mold is connected to a rear baffle, the outer periphery of the air intake duct paving mold is provided with a lip paving mold, and an arc-shaped lip paving surface is formed between the lip paving mold and the air intake duct paving mold.

[0005] Furthermore, the air intake duct paving mold is formed by splicing multiple templates.

[0006] Furthermore, the lip paving mold is formed by splicing together multiple strip molds.

[0007] Furthermore, the arc-shaped lip paving surface includes a portion of the arc-shaped paving surface located on the air inlet paving mold and a portion of the arc-shaped paving surface located on the lip paving surface.

[0008] Furthermore, the front baffle and the rear baffle are provided with lifting ears.

[0009] Compared with the prior art, the beneficial effects of the present invention are: the present invention is used to lay out the aircraft air inlet, and the lip and the air inlet are laid out together. Compared with the traditional metal lip that is processed and then installed on the air inlet, the problem of difficulty in manufacturing the air inlet lip parts is solved, and the manufacturing difficulty is reduced. It has the advantages of light weight, low cost, good mechanical properties, and high assembly precision; the lip and the air inlet are directly molded as one piece, avoiding the risk of fasteners connecting the two entering the engine, while reducing the number of parts. At the same time, the air inlet lip is formed by a female mold to improve the surface molding quality of the lip. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1-5The shown mold is an integrated molding mold of an air intake duct and a lip, comprising an air intake duct paving mold 100, the front end of the air intake duct paving mold 100 is connected to a front baffle 200, the rear end of the air intake duct paving mold 100 is connected to a rear baffle 300, and the periphery of the air intake duct paving mold 100 is provided with a lip paving mold 400, and an arc-shaped lip paving surface 600 is formed between the lip paving mold 400 and the air intake duct paving mold 100.

[0019] Specifically, the air intake duct paving mold 100 is a conformal structure of the air intake duct, and the lip paving mold 400 is installed on the outer periphery of the air intake duct paving mold 100 through fasteners (bolts).

[0020] It should be noted that the design of the front baffle 200 and the rear baffle 300 facilitates the assembly of the air intake duct paving mold 100. The air intake duct is paved on the periphery of the air intake duct paving mold 100, and the lip is paved at the connection between the air intake duct paving mold 100 and the lip paving mold 400 to form a lip structure.
