Casting furnace hole plugging device

Abstract

The invention discloses a casting furnace hole plugging device. The casting furnace hole plugging device comprises a main shaft, a plurality of connecting plates and limiting blocks, the bottoms of the connecting plates are rotationally mounted on the main shaft, adjusting grooves are formed in the tops of the connecting plates, mounting rods penetrate through the adjusting grooves to be connectedto the connecting plates, the mounting rods are connected with a plug, supporting rods are further arranged between the connecting plates, operating rods are connected to the outer sides of the connecting plates, a support is fixed above a furnace hole in the outer side of the furnace wall, the main shaft is arranged on the support, a supporting table is arranged on one side of the furnace hole below the main shaft, and the limiting blocks are installed on the supporting table to block the operating rods and fixed to the supporting table through a pin shaft. By means of the casting furnace hole plugging device, an operator can safely and rapidly block the furnace hole, the blocking effect is good, the operation is easy; a traditional mode that the operator uses a long rod with the plug toextrude the furnace hole and block the furnace hole is replaced, the situation that molten metal splashes and causes injuries to the operator is avoided, and the operation process is safer.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a casting furnace plug introduction device. Background technique [0002] The casting furnace uses the medium frequency induction furnace on the equipment used in the original foundry industry. Casting is to smelt the metal into a liquid that meets certain requirements and pour it into the mold. After cooling, solidification, and cleaning, it has a predetermined shape and size. and performance of the casting process. Because the casting blank is almost formed, the purpose of free machining or a small amount of machining reduces the cost and reduces the time to a certain extent. Casting is one of the basic processes of the modern manufacturing industry. Casting with medium frequency induction furnace can be more efficient, more energy-saving, cost-saving and environmentally friendly. [0003] But general casting furnace is all provided with furnace eye, and the effect of stopper...

Problems solved by technology

[0003] But general casting furnace is all provided with furnace eye, and the effect of stopper is to be used for blocking furnace eye, prevents the molten metal of foundry furnace from leaking out, and prior art stopper is made up of the long rod of a conical plug head, and production uses At the same time, align the plug head with the furnace eye, squeeze it hard to the furnace eye, and finally block the furnace eye. During the process, the splashed molten metal can easily cause injury to the operator
