Description

Technical Field

[0001] The utility model relates to a horizontal static pressure line casting mould, belonging to the technical field of static pressure line moulds. Background Art

[0002] Static pressure molding is to preliminarily compact the molding sand through the pre-compacting effect of airflow, and then finally compact the molding sand through the hydraulic pressure head. Hydraulic drive is often used in static pressure line molding; the specific hydraulic station selection varies according to the user's requirements for efficiency; generally used in pairs, one for the upper and the other for the lower, and the molding compactness is also adjusted according to the actual requirements of the user.

[0003] The utility model with patent number 201820318757.9 provides a horizontal static pressure line casting mold, in which exhaust fins are directly made on the mold plate and multiple groups are provided in the surrounding directions. When pouring molten iron, the gas can be discharged directly from the exhaust channel formed by the exhaust fins, without having to consider the sand falling problem caused by the bending of the exhaust needle; at the same time, during casting, the molten iron at the exhaust channel solidifies first, and the heat conduction also accelerates the solidification of the molten iron near the exhaust channel, which plays the role of cooling iron and prevents the occurrence of shrinkage holes in the wall thickness; however, the existing static pressure line mold cannot quickly replace molds of different sizes. When replacing the mold, it is fixed with bolts, which is more troublesome to disassemble and not very practical, which slows down the work efficiency of workers. Utility Model Content
