Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 3, a casting mold comprises an outer cylinder 1 and a casting pipe 2, wherein the outer cylinder 1 is used for receiving a cast bar and providing a movement space for the casting pipe 2, the casting pipe 2 is used for providing a shaping place for the casting of the bar, a rotating groove is arranged in the outer cylinder 1, a first gear 101 is rotatably connected in the rotating groove, and the first gear 101 is in transmission connection with a motor 103 through a second gear 102;

the casting pipe 2 is arranged inside the outer barrel 1, a pouring gate 3 is arranged above the casting pipe 2 at the top end of the outer barrel 1, a through hole is formed in the bottom end of the outer barrel 1, a cold water pipe 401 and a return pipe 402 are arranged in the through hole, and the cold water pipe 401 and the return pipe 402 are both communicated with the water tank 4.

In a specific embodiment of the present invention, a through hole is formed in the middle of the first gear 101, and the through hole is internally threaded with a casting pipe 2.

According to the invention, the second gear 102 on the motor 103 drives the first gear 101 to rotate, so that the casting pipe 2 rotates and moves up and down in the outer cylinder 1 by utilizing threads, the length change of the casting pipe 2 is realized, and a foundation is further provided for processing bars with different lengths.

As a specific embodiment of the invention, a water tank 201 is arranged at a position close to the bottom end of a casting pipe 2, on one hand, cold water is circulated in the water tank 201 to quickly cool molten metal into a bar, on the other hand, the molten metal in the casting pipe 2 is divided into three states by the cooling effect, wherein the first state a is a liquid state, the second state b is a solid-liquid coexisting state, and the third state c is a solid state, so that the subsequent work is convenient to carry out, the water tank 201 is spirally distributed, and a water inlet end and a water outlet end of the water tank 201 are respectively communicated with a cold water pipe 401 and a return pipe 402 to provide cooling for bar casting.

As a specific embodiment of the present invention, the lengths of the cold water pipe 401 and the return pipe 402 are both greater than the length of the molten metal pipe 2, so as to prevent the cold water pipe 401 and the return pipe 402 from being separated from the water tank 201 when the molten metal pipe 2 moves in the outer cylinder 1, so that the cold water cannot cool the molten metal, the cold water pipe 401 is provided with a submersible pump 403, the submersible pump 403 is fixed on the inner wall of the water tank 4, one end of the return pipe 402 located inside the water tank 4 is provided with a stopper 404, and when the molten metal pipe 2 moves in the outer cylinder 1, the return pipe 402 is prevented from being pulled out of the water tank 4, so that the water cannot flow back to the water tank 4.
