For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0046] See also Figure 1 and Figure 2 In a first aspect, an embodiment of the present application provides a casting device for metal forming, including: a casting box 10, a bracket 20, a linear drive 30 and a sealing head 40.

[0047] A pouring port 11 is provided in the pouring box 10. The pouring box 10 is used to store molten metal. After the pouring port 11 is connected to the mold, the molten metal can be poured into the mold through the pouring port 11.

[0048] The bracket 20 is fixed on the top of the casting box 10; the linear drive 30 is fixed on the bracket 20. In this embodiment, the linear drive 30 can be a hydraulic cylinder linear drive mechanism such as an oil cylinder.

[0049] The output end of the linear drive 30 extends into the casting box 10 and is fixedly connected to the sealing head 40. Specifically, the sealing head 40 is located above the casting port 11. Therefore, when the linear drive 30 drives the sealing head 40 to rise and fall, the sealing head 40 can control the opening and closing of the casting port 11.

[0050] During the application of the pouring device, when the mold is docked with the pouring port 11, the linear drive 30 drives the sealing head 40 to gradually move away from the pouring port 11, so that the pouring port 11 is opened, and then the molten metal flows into the mold from the pouring port 11. After the pouring is completed, the linear drive 30 drives the sealing head 40 to press down, and the molten metal remaining on the pouring port 11 is pressed down into the mold through the downward action of the sealing head 40, so as to avoid the residual molten metal and seal the pouring port 11, and then the mold that has not been poured can be replaced for a new round of pouring.

[0051] It should be noted that the linear drive 30 is connected to a controller. After the above-mentioned pouring is completed, the process of controlling the linear drive 30 to press down is controlled by the controller, and the basis for judging whether the pouring is completed can be judged according to the opening time of the pouring port 11, that is, after the linear drive 30 drives the sealing head 40 to rise for a preset time, it is considered that the mold has been poured, and then the linear drive 30 is controlled to drive the sealing head 40 to press down.

[0052] Similarly, the pouring device may be provided with an in-position sensor 50; the in-position sensor 50 may be installed on the pouring box 10 or the bracket 20, and electrically connected to the controller, for sensing whether the mold is docked with the pouring port 11. After the in-position sensor 50 senses that the mold is transported to the in-position position, that is, the mold is docked with the pouring port 11, the linear drive 30 is controlled to drive the sealing head 40 to rise, so as to realize automatic control of the pouring process, and the in-position sensor 50 ensures that the controller controls the linear drive 30 to start after receiving the signal of the in-position sensor 50, which can improve the accuracy of the pouring amount control and reduce the weight error of the formed metal in the mold.

[0053] In a further improved embodiment, the bottom of the sealing head 40 is provided with a chamfer, so that the bottom of the sealing head 40 can partially pass through the pouring port 11 .

[0054] Specifically, during the process of pressing the sealing head 40 downward, the sealing head 40 can partially pass through the pouring port 11 through its chamfer, and the other part of the sealing head 40 fits with the edge of the pouring port 11 to better press down the residual molten metal on the pouring port 11 and achieve a better sealing effect.

[0055] In application, there may be a plurality of linear drivers 30 and sealing heads 40 ; there may be a plurality of pouring ports 11 ; and the plurality of pouring ports 11 , linear drivers 30 and sealing heads 40 may correspond one to one.

[0056] A plurality of pouring ports 11 can be connected to a plurality of molds at the same time, thereby cooperating with a plurality of linear actuators 30 and sealing heads 40 to improve operating efficiency.

[0057] On the basis of the above-mentioned embodiment, a plurality of linear drivers 30 may be arranged in a straight line; a plurality of pouring ports 11 may be arranged in a straight line; and a plurality of sealing heads 40 may be fixedly connected in synchronous motion.

[0058] For example, in this embodiment, the output ends of the plurality of linear actuators 30 may all be connected to the connecting plate 23; specifically, the connecting rod 31 connected to the output end of the linear actuator 30 may be fixedly connected to the connecting rod 23, and then the connecting rod 31 may be connected to the sealing head 40. The connecting rod 23 allows the plurality of connecting rods 31 and the plurality of sealing heads 40 to rise and fall synchronously, thereby avoiding the problem that the connecting rod 31 is prone to force in other directions when a single linear actuator 30 controls the rise and fall of a single sealing head 40, thereby causing the movement accuracy of the sealing head 40 to deviate. In other words, the sealing head 40 can be raised and lowered better along a straight line, thereby improving the sealing effect and stamping effect on the pouring port 11, and improving the service life of the sealing head 40 and the pouring box 10.

[0059] In this embodiment, the linear actuator 30 can use a cylinder with a hydraulic stroke of 100-120mm, a cylinder diameter of 60-63mm, and a thrust of 5 tons. The inventors found that the existing cylinders used for pouring devices mostly use cylinders with a stroke of more than 200mm and a cylinder diameter of 80mm, and a thrust of 8 tons. When used on the pouring box 10, it is easy to cause bulging on the bottom plate of the pouring box 10, resulting in low sealing. For this reason, the use of a cylinder with a thrust of 5 tons in this solution can effectively reduce the action time, reduce the amount of hydraulic oil used, and avoid the problem of reduced sealing due to excessive thrust.

[0060] In one embodiment, a heat insulation board 21 is disposed on the bracket 20 ; the heat insulation board 21 is disposed between the linear drive 30 and the casting box 10 .

[0061] The heat insulation plate 21 can isolate the linear drive 30 from the high-temperature molten metal below, thereby protecting the service life of the main body of the linear drive 30 and the sealing structure on the linear drive 30.

[0062] In one embodiment, a guide member 22 is fixed on the heat insulation board 21 ; the output end of the linear drive 30 is connected to the sealing head 40 via a connecting rod 31 ; the connecting rod 31 is slidably disposed on the guide member 22 .

[0063] The guide member 22 is used to guide the lifting and lowering of the connecting rod 31, thereby ensuring the linear motion effect of the connecting rod 31. Figure 2 The guide member 22 may be a sleeve structure fixed on the heat insulation board 21; the connecting rod 31 passes through the sleeve structure.

[0064] On the basis of any of the above embodiments, the sealing head 40 is installed on the connecting rod 31 ; the connecting rod 31 is connected to the output end of the linear drive 30 through the spring 32 .

[0065] Specifically, the sealing head 40 in this embodiment can be made of bearing steel material and undergo a heat treatment hardening process so that it can withstand a force of more than 450 MPa. After heat treatment, the bearing steel material has the characteristics of high hardness, high wear resistance, high fatigue strength, high corrosion resistance, and good dimensional stability, which improves its durability. This can improve its sealing performance and protect its sealing port.

[0066] Meanwhile, in this embodiment, the spring 32 is selected to connect the output end of the linear drive 30 and the connecting rod 31 with a medium load diameter of 50 mm and a maximum load of 1 ton. Since the downward thrust of the linear drive 30 is relatively large, the material bearing steel can withstand a force of 4.5 tons. The spring 32 can offset part of the thrust of the linear drive 30, and the original hard seal between the sealing head 40 and the pouring port 11 is transformed into a soft seal with a buffering effect, so that the pressure between the pouring port 11 and the sealing head 40 is maintained within a corresponding range, and at the same time, there is a pre-pressure provided by the spring 32 between the sealing head 40 and the pouring port 11, which can improve the sealing effect of the pouring port 11 and improve the service life of the sealing head 40 and the pouring box 10.

[0067] In another embodiment, a limit sensing structure is provided at the output end of the linear drive 30 to limit the movement stroke of the output end of the linear drive 30 .

[0068] Specifically, the limit sensing structure may include: a limit sensor 61, a limit column 62 and a slide groove 63; the slide groove 63 is arranged on the above-mentioned sleeve structure; the limit column 62 is arranged on the connecting rod 31; the limit column 62 is slidably arranged in the slide groove 63, so that the lifting distance of the connecting rod 31 and the sealing head 40 can be limited by the cooperation of the limit column 62 and the slide groove 63. The limit sensor 61 can sense whether the limit column 61 and / or the connecting rod 31 are lifted and lowered in place, so as to determine whether the sealing head 40 effectively seals the pouring port 11, and whether the sealing head 40 effectively opens the pouring port 11.

[0069] Through the cooperation of the limit sensor 61 and the above-mentioned in-place sensor 50, the precise control of the pouring amount can be effectively improved, the molding efficiency can be improved and the weight error after molding can be reduced.

[0070] The second aspect of the present application provides a casting system, comprising: a conveyor line and any of the above-mentioned casting devices for metal forming; the casting device for metal forming is arranged above the conveyor line; the conveyor line is used to convey the mold to the casting port 11 in the casting device for metal forming.

[0071] Correspondingly, a placement sensor 50 is provided on the pouring device used for metal forming; the placement sensor is used to sense whether the mold is docked with the pouring port 11.

[0072] Through the cooperation of the conveyor line and the in-place sensor 50, automatic control of mold transmission and mold replacement can be achieved; in conjunction with the downward pressure sealing method of the sealing head 40 in the casting device, the work of the staff to repeatedly clean the residue at the casting mouth 11 can be further reduced, thereby reducing the work intensity of the staff and reducing maintenance work, and improving the safety of the operation.

[0073] The above are only preferred embodiments of the present application and are not intended to limit the present utility model. Although the present application has been described in detail with reference to the examples, those skilled in the art can still modify the technical solutions recorded in the aforementioned examples or make equivalent substitutions for some of the technical features therein.
