[0002] The prior art invention CN202498206U patent discloses a rotary casting device, which has a chassis structure, fixed on the floor of the workshop, and at least two rotating arms that can rotate relative to the chassis are installed on the upper end of the chassis; the two rotating arms can move relative to each other at an angle of 0-360°; a casting machine is installed on the other end of the rotating arm, and the casting machine can move along the rotating arm, and the rotating arm and the chassis are connected by rolling bearings or gears. The rotary casting platform can indeed achieve the effect of rotary casting, and can also increase the amount of casting and unloading within the circumference, but the device still has the following problems:

[0003] 1) The middle support is not stable, especially when the weight on the rotating arm is large, it is easy to twist or be damaged; 2) The casting is carried out by a rotary casting machine, which cannot conveniently control the casting flow rate and is prone to leakage when it is rotated or adjusted again; 3) If the control requirements for the composition of the cast steel are relatively strict, gas protection is required during casting, which cannot be achieved using this device.

[0004] Therefore, the utility model proposes a continuous casting machine casting device to solve the above-mentioned problems. Summary of the invention

[0027] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0028] See Figure 1-4 As shown, the utility model provides a continuous casting machine casting device, which is mainly used in the case where the continuous casting machine performs continuous casting. Through some reasonable designs, the continuous casting effect is achieved, and the casting quantity is increased in a unit of time.

[0029] The structure of this scheme mainly includes a walking assembly 100 and a casting assembly 200 driven and moved by the walking assembly 100; wherein the walking assembly 100 includes a support plate 101 arranged above the continuous casting machine, a driving motor 102 is installed on the support plate 101, and a screw rod 105 is installed below the support plate 101, wherein the screw rod 105 is installed on a first bearing seat 104 and a second bearing seat 107, and the first bearing seat 104 and the second bearing seat 107 are fixedly installed at the bottom of the support plate 101;

[0030] In order to achieve the matching, a sprocket is provided at the output end of the driving motor 102, and a sprocket is also provided on the side of the screw rod 105 facing the driving motor 102. The two sprockets are connected by a chain 103 to achieve linkage. The driving motor 102 drives the moving seat 106 on the screw rod 105 to move, and a connecting base plate 111 is fixedly installed at the bottom of the moving seat 106. The front and rear ends of the screw rod 105 are provided with slide rails 108, and a slider 109 is sleeved on the slide rail 108. The slider 109 is also fixedly connected to the connecting base plate 111. Specifically, a connecting block 110 is provided at the bottom of the slider 109, and the connecting block 110 is locked with the connecting base plate 111. In order to effectively match the slide rail 108 with the screw rod 105, a connecting block 110 is provided at the bottom of the slider 109, and the connecting block 110 is locked with the connecting base plate 111.

[0031] See attached for details Figure 2-4The casting assembly 200 is installed below the connecting bottom plate 111, and includes a casting box 201. A feed port 202 is provided on the top of the casting box 201. The feed port 202 is connected to a feed pipe to ensure a continuous supply of metal raw materials. A discharge main pipe 206 is provided below the casting box 201. The discharge main pipe 206 radiates outward with a plurality of obliquely arranged guide pipes 207. The bottom of the guide pipe 207 is provided with a sleeve 208 structure larger than the pipe diameter, and a discharge needle tube 209 is provided at the discharge end. In order to achieve the guiding effect, the guide pipe 207 is an L-shaped pipe with an obtuse angle, and the discharge end is vertically downwardly arranged. The vertical downward arrangement at the discharge end is to prevent the oblique arrangement from eventually leading to waste of molten metal. An electric control valve is provided in each of the guide pipes 207. The periphery of the guide tube 207 is provided with a protective cover 205 that can be raised and lowered and moved. Specifically, the top of the protective cover 205 is fixedly connected to the moving rod 204, and the moving rod 204 is fixed to the movable end of the driving cylinder 203. The driving cylinder 203 is installed on the outer wall of the casting box 201. In order to achieve an effective sealing effect, an annular sealing ring is sleeved on the bottom of the protective cover 205, and an air inlet pipe 210 is connected to the protective cover 205. When in use or for protecting easily oxidizable molten metal, inert gas is introduced into the protective cover 205. At this time, the protective cover 205 is buckled above the material to be cast to form a sealed, inert gas space effect as much as possible. When designing, it should also be noted that the protective cover 205 should fully wrap the guide tube 207 and a certain safety distance needs to be set.

[0032] When the utility model is in use, metal liquid is introduced into the casting box, and then the control valve arranged inside is opened to guide the liquid of each part to the corresponding guide pipe, and the electric control valve in the guide pipe is not opened. Before that, the mold to be cast needs to be arranged neatly in a straight line, and can be placed in the direction set by referring to the support plate, and then driven to move by the driving motor, and the driving motor drives the screw rod to rotate, so that the screw rod drives the moving seat to move, and the casting box connected to the moving seat and the slider is also driven after the rotation. When it arrives at the designated location, the protective cover is driven by the driving cylinder to descend for protection first, and then the corresponding electric control valve in each guide rod is opened to allow the metal liquid to flow out in small amounts and accurately along the discharge needle tube. In the attached figure, we provide a structure of 4 guide pipes, so that the casting effect of four products can be achieved at one time. At the same time, when the casting is completed, the electric control valve is closed, and the driving motor drives the casting box to move to the next casting position to achieve the effect of continuous casting. Since the casting volume is constant, it can be moved after the casting is completed. Of course, in order to facilitate observation, explosion-proof glass can also be installed on the surface of the protective cover. At the same time, it should be noted that since the casting box in this solution is movable, the pipe matching it should be long enough.

[0033] The exemplary implementation scheme of the present disclosure is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
