[0001] The invention relates to the technical field of continuous casting machines, and in particular to a metallurgical continuous casting machine for precision casting engineering. Background Art

[0002] Metallurgy is the process and technology of extracting metals or metal compounds from minerals and using various processing methods to make metal materials with certain properties. The continuous casting machine is a production process that continuously casts high-temperature molten steel into ingots with a certain cross-sectional shape and certain size specifications. The equipment required to complete this process is called a continuous casting equipment set.

[0003] The existing metallurgical continuous casting machines used in precision casting projects currently have poor demoulding effects when in use. Usually, the metallurgical continuous casting machine mold is difficult to remove after forming, which affects the working efficiency of the metallurgical continuous casting machine, and the existing equipment is prone to damage to the product during demoulding. Summary of the invention

[0004] In order to solve the problem in the prior art that the continuous casting machine mold is difficult to separate after molding, the present invention provides a metallurgical continuous casting machine for precision casting engineering.

[0005] The technical solution of the present invention is:

[0006] The present invention provides a metallurgical continuous casting machine for precision casting engineering, comprising a vertical shaft, the upper end of the vertical shaft is rotatably connected to the lower end of the movable rod of the hydraulic rod, the upper part of the vertical shaft is rotatably mounted on a gear sleeve, a rotation driving device is arranged on the side of the gear sleeve, a gear of the rotation driving device and a gear sleeve are kept in meshing engagement, a sliding sleeve is mounted on the middle part of the vertical shaft by a key connection, a spring is mounted on the vertical shaft, two ends of the spring are respectively fixedly connected to the sliding sleeve and the vertical shaft, a ball socket with an opening facing downward is installed on the side of the sliding sleeve through a diameter reducing assembly, and a ball body is installed in the ball socket;

[0007] It also includes a mold, a horizontal shaft is fixedly installed on the side of the mold, the outer end of the horizontal shaft is connected to a rotating assembly, and the rotating assembly is connected to the moving frame;

[0008] A fixing plate is arranged at the bottom of the mold, and several through holes distributed in a ring shape are opened on the bottom surface of the mold. Step holes are opened at the corresponding through holes on the fixing plate, and the large diameter end of the step hole faces the bottom surface of the mold. A step rod is installed in the combined hole composed of the step hole and the through hole, and the large diameter part of the step rod located in the middle position is located inside the large diameter end of the step hole; the outer end of the step rod is a spherical surface and a part of it is exposed from the small diameter end of the step hole.

[0009] Furthermore, the variable diameter assembly includes an array of parallelogram connecting rod assemblies arranged in an annular manner on the side of the sliding sleeve, one end of the parallelogram connecting rod assembly is fixedly connected to the side of the sliding sleeve, and the other end of the parallelogram connecting rod assembly is installed with a ball socket with an opening facing downward through a connecting block.

[0010] Furthermore, the parallelogram linkage assembly has an upper rod and a lower rod distributed up and down and can rotate up and down along the hinge axis connected to the sleeve. The upper rod of the parallelogram linkage is hingedly connected to the first bracket on the upper side of the sleeve through an electric push rod.

[0011] Furthermore, an extrusion hole is provided in the middle of the bottom of the assembly of the mold and the fixed plate, an extrusion rod is arranged inside the extrusion hole, and a limiting structure for the outer end of the extrusion rod is arranged on the outer side of the fixed plate.

[0012] Furthermore, the limiting structure includes a limiting ring at the outer end of the extrusion rod and a limiting block arranged on the outer side of the fixing plate and cooperating with the limiting ring.

[0013] The beneficial effects achieved by the present invention are:

[0014] When the present invention is used, the mold is moved to the position directly below the vertical axis by the movable frame while the opening of the mold is facing downward. At this time, the ball is fitted to the surface of the fixed plate by the telescopic cooperation of the hydraulic rod and the electric push rod, and then the vertical axis and the components installed on the upper part thereof are driven to rotate synchronously by the rotating drive device. At this time, the ball rolls on the surface of the fixed plate. While rolling, the ball is continuously approached and moved away from the center of the fixed plate by adjusting the telescopic expansion and contraction of the hydraulic rod and the electric push rod. In this process, the high-speed movement of the rolling ball can continuously collide with the spherical surface of the outer end of the step rod, and the collision can transmit force to the bottom surface of the part to be demolded in the mold through the step rod, and can continuously strike different positions of the bottom of the part to be demolded, so that the part to be demolded can form vibrations of different frequencies, so that the part to be demolded can be separated from the mold through vibration. Finally, the hydraulic rod is extended to completely move the part to be demolded out of the mold through the push-out extrusion rod, so that the part to be demolded can be smoothly demolded. This demolding method can eject the part to be demolded with less force, reduce damage to it, and realize efficient and continuous casting demolding. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1 As shown, it also includes a mold 13, a horizontal axis 14 is fixedly installed on the side of the mold, the outer end of the horizontal axis 14 is connected to a rotating component, and the rotating component is connected to a moving frame (not shown in the figure, conventional technology, no need to repeat), the mold 13 is moved to the bottom of the vertical axis by the moving frame while the opening of the mold is facing downward, a fixed plate 15 is set at the bottom of the mold, and a number of through holes 16 distributed in a ring are opened on the bottom surface of the mold, and a stepped hole 17 is opened at the fixed plate 15 corresponding to the through hole 16, and the large diameter end of the stepped hole faces the bottom surface of the mold, and a stepped rod 18 is installed in the combined hole composed of the stepped hole 17 and the through hole, and the large diameter part of the stepped rod 18 located in the middle position is located inside the large diameter end of the stepped hole to form a limit so that the stepped rod 18 cannot move out by itself, and the outer end of the stepped rod 18 is a spherical surface and a part of it is exposed from the small diameter end of the stepped hole.

[0021] The combination of the mold and the fixed plate is provided with an extrusion hole 19 in the middle of the bottom, an extrusion rod 20 is arranged inside the extrusion hole 19, and a limiting structure for the outer end of the extrusion rod is arranged on the outer side of the fixed plate, which ensures that the extrusion rod cannot move out by itself.

[0022] The limiting structure includes a limiting ring 21 at the outer end of the extrusion rod and a limiting block 22 arranged on the outer side of the fixed plate and cooperating with the limiting ring 21.
