Description

Technical Field

[0001] The invention relates to the field of composite material molding production, in particular to a molding die device for a buoyancy tank shell of a composite material. Background Art

[0002] Composite materials have been widely used in the manufacture of buoyancy tank shells for ocean exploration equipment and deep-sea submersibles due to their light weight and high strength. These materials are usually composed of high-strength fibers (such as glass fiber, carbon fiber, polyester fiber, etc.) and resin matrices, and have excellent properties such as high strength, low density, and corrosion resistance. Traditional buoyancy tank shell molding methods mainly include hand lay-up molding, compression molding, winding molding, etc. These methods meet production needs to a certain extent, but there are still many shortcomings in production efficiency, product quality and cost control. In recent years, with the development of automation technology and new materials, composite material molding technology has gradually developed in the direction of high efficiency, precision and low cost;

[0003] In the molding process of the composite buoyancy tank shell, the traditional method usually requires the operator to manually or use the external frame plate equipment for positioning to fix and adjust the plate to be processed inside the mold. After adjusting the positioning, it needs to be taken out of the mold to prevent the external frame plate equipment for auxiliary positioning from affecting the processing process. In the molding process, this method has cumbersome operation steps and low efficiency. At the same time, due to the inaccurate manual adjustment of the position in the traditional method, it is easy to deviate, or it is easy to stick, collide and offset when the auxiliary positioning frame plate equipment is removed, which affects the overall quality and reliability of the product. As a result, the molding method of the composite buoyancy tank shell has problems such as unstable placement, low production efficiency, unstable product quality, dislocation due to uneven force, and complicated operation. Especially in the production of buoyancy tank shells with complex shapes, the limitations of traditional methods are more obvious, and it is difficult to meet the high performance and high reliability requirements of modern ocean detection equipment and deep-sea submersibles for the buoyancy tank shell. To this end, we propose a molding mold device for the buoyancy tank shell of a composite material. Summary of the invention
