The purpose of the invention is realized by the following technical scheme:

the integral casting equipment for the ripple-free cooling and discharging of the ingot blank comprises an inner rotating disc and an outer rotating disc which have the same rotation center, an ingot mould disc which is arranged on the inner side of the outer rotating disc and is concentric with the inner rotating disc, a group of fixed casting moulds which are uniformly arranged on the ingot mould disc in a radial shape, and a group of jacking devices which are respectively arranged at the bottom of each fixed casting mould and are used for jacking the ingot blank; the inner rotary disc and the outer rotary disc synchronously and intermittently rotate and rotate in opposite directions under the control of the inner rotary disc transmission device and the outer rotary disc transmission device respectively; a temporary molten liquid storage tank is arranged on the inner rotary table, a molten metal inlet pipe is arranged on the temporary molten liquid storage tank, a quantitative control device for controlling the flow of molten metal is arranged at a liquid outlet of the temporary molten liquid storage tank, and the quantitative control device is connected with a casting pipeline and used for casting molten metal to the fixed casting mold through the casting pipeline; still install the cantilever that stretches to fixed mould on the inner turntable, install on cantilever outer end upper portion and take out the ingot blank in the fixed mould and place the first ingot manipulator of getting on the outer turntable, the outer end bottom of cantilever still installs the drawing of patterns hammer that strikes jacking device, and the cantilever staggers with the mounted position of casting pipeline.

The number of the fixed casting molds is odd. The inner turntable transmission device and the outer turntable transmission device are connected with the same motor. A conveying mechanism for conveying the ingot blank is arranged outside the outer turntable, and a second ingot taking manipulator for transferring the ingot blank from the outer turntable to the conveying mechanism is arranged between the outer turntable and the conveying mechanism.

When the ingot blank production device is adopted to produce ingot blanks, the casting mould disc is fixed, and the casting pipeline rotates along with the rotation of the inner rotary disc, so that a production mode that the casting mould is fixed and the casting opening rotates to the fixed casting mould to continuously cast one by one is realized. Because the casting mould is still and the solidification and cooling of the molten metal are finished in a static state, fine ripples are not generated on the surface of the ingot blank obtained by casting, the surface is smooth and bright, and the appearance quality is good. The continuous casting of the casting opening to the fixed casting mould one by one is carried out due to the continuous rotation of the casting opening, so that the higher production efficiency is still kept. The molten metal in the fixed casting molds which are cast sequentially is solidified and cooled sequentially to form ingot blanks, the cantilevers which rotate along with the inner rotary disc sequentially rotate to the sides of the fixed casting molds which form the ingot blanks, the demolding hammers strike the jacking devices at the bottoms of the fixed casting molds in sequence to jack the ingot blanks in the fixed casting molds, and the first ingot taking manipulator takes out the ingot blanks immediately and places the ingot blanks on the outer rotary disc for transportation.

The invention is further described below with reference to the accompanying drawings.

The integral casting equipment for the waveless cooling and discharging of the ingot blank as shown in fig. 1 comprises an inner rotary disk 7 and an outer rotary disk 2 with the same rotation center, an ingot mould disk which is arranged at the inner side of the outer rotary disk 2 and is concentric with the inner rotary disk 7, a group of fixed casting moulds 3 which are uniformly arranged on the ingot mould disk in a radial shape, and a group of jacking devices 17 which are respectively arranged at the bottom of each fixed casting mould 3 and are used for jacking the ingot blank 13. The inner rotary disk transmission device 6 is connected with the inner rotary disk 7, the outer rotary disk transmission device 1 is connected with the outer rotary disk 2, and the inner rotary disk transmission device 6 and the outer rotary disk transmission device 1 can be connected with the same motor 18 or can be respectively connected with the respective motors. The reverse synchronous intermittent rotation of the inner rotary disc 7 and the outer rotary disc 6 is realized by driving the outer rotary disc transmission device 1 and the inner rotary disc transmission device 6 through a motor. Be provided with molten liquid on the inner rotary disk 7 and keep the tank 8 temporarily, be provided with feed liquor pipe 5 on the molten liquid keeps the tank 8 temporarily, the liquid outlet of molten liquid keeps the tank 8 temporarily is provided with the quantitative control device 9 of control molten metal flow, and quantitative control device 9 is connected with casting pipeline 4 to through casting pipeline 4 to fixed mould 3 casting molten liquid. A cantilever 15 extending to the fixed casting mould is further installed on the inner rotary table 7, a first ingot taking manipulator 11 capable of taking out the ingot blank 13 in the fixed casting mould and placing the ingot blank on the outer rotary table 2 is installed on the upper portion of the outer end of the cantilever, a demoulding hammer 16 of a knocking jacking device 17 is further installed at the bottom of the outer end of the cantilever 15, and the cantilever 15 and the casting pipeline 4 are arranged in a staggered mode at a certain angle so as to avoid mutual interference. A conveying mechanism 14 for conveying the ingot blanks is arranged outside the outer rotating disc 2, and the ingot blanks 13 temporarily stored on the outer rotating disc 2 are transferred to the conveying mechanism 14 by the second ingot taking manipulator 12 and conveyed away.

When the invention works, the molten metal continuously flows into the temporary molten metal storage tank 8 through the liquid inlet pipe 5, and the temporary molten metal storage tank always keeps a certain volume of metal casting liquid in the working process, the quantitative control device 9 under the temporary molten metal storage tank is in an intermittent working mode, namely, the liquid feeding and the liquid stopping are realized, the amount of the molten metal flowing into the casting pipeline 4 is controlled to be equal each time, in the process of casting an ingot blank in the casting pipeline, the inner rotary plate 7 and the outer rotary plate 2 are both still, the demolding device 10 takes out an ingot blank which is cast and cooled previously, and the first ingot taking manipulator takes out the ingot blank and puts the ingot blank on the outer rotary disc 2, then the second ingot taking manipulator takes off an ingot blank from the outer turnplate, the ingot blank is put on the conveying mechanism 14 to be conveyed away, namely, when an ingot is cast, the ingot is demolded, the ingot is taken out and put on the outer turntable, and the ingot is taken away from the outer turntable.
