Description

Technical Field

[0001] This utility model relates to the field of screw forming mold technology, specifically a mold for forming aircraft screws. Background Technology

[0002] Aerospace screws are fasteners specifically designed for use in aerospace applications. They are made from specific materials, possess unique properties or applications, and meet the specialized technical requirements of aerospace. Aerospace fasteners are generally used in aircraft, satellites, rockets, and other aerospace vehicles. They are a typical high-end fastener and an essential basic component in spacecraft, with performance requirements far exceeding those of fasteners in other fields. Aerospace fasteners can be categorized into many types based on different classification standards, each containing numerous different specifications and varieties to meet the diverse needs of different materials and structures.

[0003] Traditional aircraft screws are produced by casting to improve their structural strength. However, during the casting process, excessively high temperatures can cause internal stress during cooling, resulting in substandard production quality. Furthermore, traditional molds can only produce one aircraft screw at a time, leading to a low production yield. Additionally, molten steel may spill out of the casting port during casting, posing a safety hazard.

[0004] Therefore, there is a need to provide a mold for forming aerospace screws. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) In the production of aviation screws, the mold for forming aviation screws first casts the aviation screws through a mold closing mechanism and a material injection mechanism. After casting, the coolant inside the water tank is pumped to the first cooling coil, the connecting hose and the second cooling coil by a pump. The cast part is cooled by the first cooling coil and the second cooling coil. The coolant inside the first cooling coil and the second cooling coil is cooled by a refrigeration component.

After casting, the first mold is pulled away from the second mold by the cylinder, and the casting can be taken out, which is convenient for demolding. At the same time, the locking block engages with the first locking slot, and then the mounting frame is deflected to make the mounting frame contact the connector. The connector is connected to the mounting frame by the connecting rod, and the raw material is poured into the first screw mold and the second screw mold through the auxiliary feeding port, which can prevent molten iron from spilling and improve the safety of the operator.
