Abstract

The molding die used for the central fixing ring of the satellite reflector composite material in the present invention comprises: a die set assembly, a storage space is arranged in the die set assembly; a positioning assembly, the positioning assembly is arranged in the storage space; A wedge assembly, the wedge assembly is arranged in the storage space, and the wedge assembly is arranged around the positioning assembly; wherein the positioning assembly includes: a mold core, and the mold core is arranged at the bottom of the storage space ; the first block unit, the first block unit is set on the outside of the core; the second block unit, the second block unit is set on the outside of the core, the first The second block unit is arranged above the first block unit; the pressing plate is sleeved on the outside of the mold core. Compared with the prior art, the present invention has the following advantages: 1. Improve the feasibility of the central fixing ring. 2. Realize the overall forming of complex ribs in multi-layer flanges. 3. Achieve effective weight loss effect.

Description

Technical field [0001] The present invention relates to an application for the center of the satellite reflector composite mold. Background technique [0002] As the antenna satellite structure is increasing, the structure of the antenna member is increasing, and the stiffness and accuracy requirements based on the antenna member are high. The components need to increase the plurality of strengthening ribs to improve the integration of the whole, while in order to satisf weight Requirements, alternative metal components that have low density, high strength, and rigidity, have become main trends. [0003] The design of the composite molding die is designing to ensure the quality of the components, in which the method of reinforcing the reinforcement is lacking in the mold design, the position of the reinforcing rib is not accurate, and the rework is required. The strength of the reinforcing rib is not reached. The multi-layer flange has a reinforcing center fixed ring member, thro...
