Abstract

The invention discloses a molding die for a satellite reflector composite center fixing ring, comprising: a die sleeve assembly, wherein a storage space is arranged in the die sleeve assembly; a positioning component, wherein the positioning component is disposed in the storage space; a wedge assembly, wherein the wedge assembly is disposed in the storage space and around the positioning component. The positioning component includes: a core disposed at the bottom of the storage space; first splicing block units, the first splicing block units sleeving the outer side of the core; second splicing block units, the second splicing block units being disposed on the outer side of the core and on the first splicing block units; and a pressure plate, the pressure plate sleeving the outer side of the core. Compared with the prior art, the present invention has the following advantages of: 1, improving the feasibility of the center fixing ring; 2, realizing the integral molding of complex ribs of multi-layer flanges; and 3, achieving an effective weight loss.

Description

technical field [0001] The invention relates to a molding die suitable for the central fixed ring of composite material of satellite reflectors. Background technique [0002] With the increase in the use of antenna satellite structures, the structure of antenna components is becoming more and more complex. Based on the high rigidity and precision requirements of antenna components, multiple ribs need to be added to the components to improve the overall strength. At the same time, in order to meet the requirements of light weight It has become the main trend to replace metal components with carbon fiber components with low density, high strength and high rigidity. [0003] The design of the positioning method of the composite molding die plays a decisive role in ensuring the quality of the components. In the past, for these components with ribs on the flange, there was a lack of positioning methods in the mold design, and the positions of the formed ribs were not accurate, re...
