Pouring system capable of preventing molten iron from overflowing and improving precision

Abstract

The invention relates to the technical field of casting pouring, and discloses a pouring system capable of preventing molten iron from overflowing and improving precision, the pouring system comprises a lower section mold base and an upper section mold base adaptively mounted on the lower section mold base, the bottom of the upper section mold base is provided with an inward concave section groove, and the groove wall of one side, far away from the lower section mold base, in the section groove is provided with a cavity. The top of the lower section mold base is provided with a section table which protrudes upwards and is matched with the section groove, and the top of the section table is provided with a section core matched with the cavity. When the mold is closed, a gap area is formed between the profile groove and the profile table. By changing the cavity and core structures of the upper section mold base and the lower section mold base and arranging the sealing convex blocks and the sealing grooves on the mold walls of the inclined gaps between the upper section mold base and the lower section mold base, molten iron is prevented from flowing out of a parting surface during pouring, the loss of the molten iron is reduced, and the production efficiency is improved. The smooth production process, the production efficiency of products and the safety and stability of the working environment of operators are guaranteed.

Description

technical field [0001] The invention relates to the technical field of casting pouring, in particular to a pouring system for preventing overflow of molten iron and improving precision. Background technique [0002] Iron products are the most widely used metal structural materials in industry. They have been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. Due to the rapid development of industrial economy, the demand for iron product structural parts is increasing day by day. The research on the weldability of iron products has also been deepened. [0003] The current iron products can be applied to many places, so the current iron products will have various shapes. For some simple shapes, they can be processed through simple cutting, welding and other processes, but for more complex shapes Can only be processed by casting. [0004] The current casting technology requires the operator to pour molten iron into t...

[0004] The current casting technology requires the operator to pour molten iron into the sand box for pouring. However, since the projected area of ​​the casting and the gating system accounts for 40.4% of the total area of ​​the sand box, the lifting force is greater than The sum of the upper mold base and the weight of the weight makes the upper mold base lift up, and the molten iron flows out from the parting surface and falls into the track, resulting in the problem of running molten iron. It is necessary to remove the overflow on the production line in time during production and solidify The iron block formed in the end seriously restricts the production of products, the production efficiency is low, and the operator is very prone to danger when working in such a working environment
