Problems solved by technology

Although the traditional method of this scheme shortens the cooling treatment time, it still has many disadvantages: 1. High production cost, difficult operation, loud air noise on site, and potential safety hazards in high-temperature gas; 2. The scope of application is limited, and it is not suitable for some Castings with small size, many internal chills, complex shapes or high quality requirements, and the cooling efficiency is still low

Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] The cooling process of molding sand casting is the process in which the heat of casting high-temperature molten iron is transferred to the surrounding environment through molding sand. Since the thermal conductivity of molding sand is small, it is the main heat-resistant material for casting cooling. Generally, sand boxes use box belts to ensure the strength of the sand box. and rigidity, while the size of the box belt is mostly between 100mm-200...

Abstract

The embodiment of the invention discloses a casting pressure plate which comprises an upper shape pressure plate, a lower shape pressure plate and rib plates, wherein the upper shape pressure plate is arranged opposite to the lower shape pressure plate; and the rib plates are arranged at the edge of the lower shape pressure plate, are vertically intersected with one another and are solid rib plates. The embodiment of the invention also provides a manufacturing method of a casting.

Description

technical field [0001] The invention relates to the field of mechanical casting, in particular to a manufacturing method of a mold pressing plate and a casting. Background technique [0002] Casting is the process of smelting metal into a liquid that meets certain requirements and pouring it into a molded mold, cooling, solidifying, and cleaning to obtain a casting with a predetermined shape, size, and performance. The pouring temperature of iron castings is generally 1260°C to 1450°C. After the high-temperature molten iron enters the mold, as the temperature continues to decrease, the structure changes continuously. After graphite precipitation, eutectic transformation, eutectoid transformation and other treatment processes, the casting is finally formed. Depending on the wall thickness of the casting and the cooling conditions, it may take several hours to dozens of days for the molten iron to drop from high temperature to the box temperature. Especially for large-scale c...
