Description

Technical Field

[0001] The utility model relates to the technical field of casting equipment, in particular to a molten steel pouring and pouring device for precision casting. Background Art

[0002] Casting is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and then cooling and solidifying it to obtain a part or blank. Precision casting is a general term for the process of obtaining castings with precise dimensions. Compared with the traditional sand casting process, precision casting obtains castings with more precise dimensions and better surface finish. It includes: investment casting, ceramic mold casting, metal mold casting, pressure casting, and lost foam casting. Precision casting is also called lost wax casting. Its products are precise, complex, and close to the final shape of the parts. They can be used directly without or with little processing. It is an advanced process for near-net-shape forming. In the process of precision casting, some parts need to be cast with molten steel.

[0003] For example, the Chinese patent publication number CN215160363U discloses a molten steel pouring device for precision casting, including a frame and a cylinder, a horizontal plate is slidably installed on the top of the frame, horizontal racks are fixedly installed on both sides of the inner wall of the frame, and a driving motor 1 is fixedly installed on both sides of the top of the horizontal plate. In this molten steel pouring device for precision casting, the driving motor 2 drives the horizontal axis to rotate and then the gear 2 rotates. Under the meshing action of the gear 2 and the vertical rack, the vertical rack moves upward, and then drives the hanger to move up and down. At the same time, the winding disk also reels the wire rope, and the wire rope also drives the vertical rack to move upward. On the basis of the wire rope hoisting, a vertical rack is added to guide the position of the hanger, so that the hanger will not slide during the movement, and thus will not cause the sliding of the cylinder, and the molten steel inside is not prone to splashing and leakage, which greatly improves the safety level and has good stability.

[0004] The existing technology has the following problems:

[0005] When the prior art performs lateral movement, two motors are respectively engaged with the racks to drive the device to move, which causes the device to easily deviate during movement, resulting in molten steel splashing. At the same time, when the cylinder of the prior art moves up and down, there is no limit guide for the device, resulting in poor stability during lifting and lowering, reducing the practicability of the device.
