Description

Technical Field

[0001] The utility model belongs to the technical field of buoyancy material molding equipment, and in particular relates to a deep-sea buoy main body casting mold. Background Art

[0002] Hollow microsphere buoyancy material is a composite material made by filling hollow glass microspheres into a pre-modified resin matrix, also known as a two-phase composite foam material. Hollow microsphere buoyancy material has the advantages of high compressive strength, low density, seawater corrosion resistance, low water absorption, etc. Its density is generally 0.4-0.6g / cm3, and its compressive strength is 40-100MPa. It can be used in underwater exploration equipment, offshore buoys, various manned (unmanned) deep-water submersibles, offshore oil systems, marine mining systems and other marine fields.

[0003] Buoyancy materials are usually formed by casting. For larger products such as elliptical floats, they are often cast in blocks and then bonded together. This method requires cutting on the bonding surface, resulting in waste of raw materials and cumbersome processes. In addition, because the density of microbeads is much lower than that of resins, and because of their poor heat dissipation performance, the curing time is often longer. When the product is formed, there will be resin deposits at the bottom that need to be cut off. Therefore, the more molding blocks there are and the larger the bottom cross-sectional area, the more serious the resin waste. When demolding the product, the mold is often knocked upside down, which can easily cause product damage.

[0004] Therefore, it is very necessary to develop a deep-sea buoy main body casting mold that can be integrally formed to solve the problems of complex buoy manufacturing operations, serious waste of resin due to deposition, and product damage due to demoulding. Utility Model Content

[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the accompanying drawings and embodiments. The implementation method can have different forms and should not be understood as being limited to the description set forth herein. The same reference numerals in the text always represent the same elements, and similar reference numerals represent similar elements.

[0033] like Figures 1 to 4 As shown, the utility model provides a deep-sea buoy body casting mold, including an upper mold 1, a side mold 2 and a lower mold 3. The upper mold 1 is provided with a forming cavity 4, a feeding chamber 5, an upper mold side flange 6 and an upper mold bottom flange 7. The feeding chamber 5 is arranged above the forming cavity 4. The feeding chamber 5 is semi-cylindrical in shape. The upper mold side flange 6 and the upper mold bottom flange 7 are respectively provided with screw holes, and the thickness of the flange surface is 3-7mm; the lower mold 3 is connected to the upper mold bottom flange 7 and the side mold bottom plate 9. The lower mold 3 is a 8mm thick square P20 mold steel plate, on which screw holes matching the side mold bottom plate 9 and the upper mold bottom flange 7 are arranged; the side mold 2 is connected to the upper mold side flange 6; the side mold body 8 is a 3mm P20 mold steel plate, and its shape is the same as the contour of the upper mold 1. The side of the side mold body 8 is provided with screw holes, and a rectangular side mold bottom plate 9 is provided below the side mold body 8. The side mold bottom plate 9 is perpendicular to the side mold body 8, and screw holes are provided on the side mold bottom plate 9.
