Abstract

An integral molding die for a motor internal insulation layer and a molding process. The die includes the following parts: an upper die body half piece and a lower die body half piece, which cooperate for usage; a mandrel assembly, which comprises a die body, and a front screw thread connection shaft and a rear screw thread connection shaft, welded to the front end and the rear end of the die body; a tail forming ring, which is in screw joint with the rear screw thread connection shaft of the mandrel assembly; a head blanking cap, which is in screw joint with the front screw thread connection shaft of the mandrel assembly; and a positioning and draft tool, which is in screw joint with the front screw thread connection shaft of the mandrel assembly. The invention makes the structure size and precision of an insulation layer preform meet the design requirements, and in the premise of satisfying the structure reliability, the invention reducing the negative quality of thermal protection.

Description

technical field [0001] The invention relates to an integral molding die and molding method for an inner heat insulating layer of an engine. Background technique [0002] With the improvement of the technical and tactical indicators of the missile weapon system, the requirements for the shape, thickness change, ablation performance and other indicators of the heat insulation layer in the engine are also getting higher and higher. It is difficult to meet the model production by using the traditional heat insulation layer patch forming technology. objective needs. [0003] At present, the technology of pasting the thermal insulation layer in the engine is traditionally using green sheets of different thicknesses to be superimposed, positioned in the engine, and vacuum pressurized and high-temperature vulcanized molding technology. The thickness of the thermal insulation layer using traditional technology cannot be changed linearly, and there are certain steps on the inner surf...
