Description

Technical Field

[0001] This utility model belongs to the technical field of casting equipment, and particularly relates to a cast iron casting equipment. Background Technology

[0002] Ladles are used in foundry workshops to receive molten metal and transfer it to the mold for pouring. Invention patent CN109530668B discloses a ladle device that uses a guide at the ladle inlet to divert the molten metal and prevent it from spilling outside the mold. However, this device requires a prime mover below the ladle inlet to drive a lead screw. If the prime mover is too close to the ladle, the high temperature of the ladle is transmitted to the prime mover simultaneously with the pouring of the molten metal. Working under constant temperature fluctuations, the prime mover is prone to damage, leading to frequent maintenance, high operating costs, and disruption to the casting process. Therefore, it is necessary to provide a casting device that can pour molten metal into the mold regardless of the amount in the ladle, and that has a long lifespan and is less prone to failure. Utility Model Content

[0003] The purpose of this utility model is to provide a cast iron casting device to solve the technical problems in the prior art where the prime mover is not suitable for setting on the ladle and the ladle is not easy to pour the molten metal into the mold as the molten metal decreases.

[0004] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0005] A cast iron casting device includes a ladle body, a guide frame, a ladle traveling mechanism, a ladle tilting mechanism, and a control box. The guide frame covers the mold and has a guide rail at the top. The extension direction of the guide rail is the same as the arrangement direction of the multiple molds.

[0006] The ladle walking mechanism includes a ladle mounting frame, a set of walking wheels, and a servo motor A. A rotating shaft is provided on the outer side of the ladle body perpendicular to the liquid outlet. The ladle body is hinged to the ladle mounting frame through the rotating shaft and is located above the mold. The set of walking wheels is located at the lower end of the ladle mounting frame and cooperates with the guide rail. The set of walking wheels is connected to the servo motor A for transmission.

[0007] The ladle tilting mechanism is mounted on the ladle mounting frame, and the ladle body is connected to the ladle tilting mechanism via a transmission connection; the control box includes a PLC controller, which is electrically and communicatively connected to the ladle walking mechanism and the ladle tilting mechanism.

[0008] The ladle tilting mechanism includes a fixed base, a lifting reel, a servo motor B, and a lifting chain. The lifting reel is mounted on the ladle mounting frame via the fixed base and bearings. The servo motor B is fixed on the fixed base and is connected to the lifting reel in a driving connection. A lifting lug is provided on the rear side of the ladle body opposite to the liquid outlet. One end of the lifting chain is fixed on the lifting reel, and the other end is fixed on the lifting lug.

[0009] The liquid outlet of the ladle body is located directly above the line connecting the liquid injection ports of multiple molds.

[0010] The number of liquid outlets in the ladle body is the same as the number of columns in which multiple molds are arranged.

[0011] The ladle mounting frame includes a mounting base and connecting lugs. The traveling wheel set is located at the lower end of the mounting base, and the connecting lugs are respectively located on the inner sides of both sides of the mounting base and rotate in cooperation with the rotating shaft.

[0012] The walking wheel set includes a driven wheel set and a driving wheel set. The driven wheel set is arranged on both sides of the mounting base near the liquid outlet of the pouring ladle body, and the driving wheel set is arranged on both sides of the mounting base away from the liquid outlet of the pouring ladle body. There are two servo motors A, which are respectively connected to the two driving wheel sets.

[0013] The ladle tilting mechanism consists of two sets, evenly arranged on the ladle traveling mechanism between the two guide rails.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a cast iron casting device. By setting up a control box with a PLC controller and a ladle walking mechanism, the ladle walking mechanism can be controlled by inputting a program into the PLC controller to control the stroke increment of the ladle walking mechanism after completing the injection of a set of molds. This allows the ladle walking mechanism to adapt to the displacement difference between the ladle body and the mold caused by the reduction of molten metal and the increase of the relative vertical tilt angle. The program of the PLC controller can be used to increase or decrease the stroke increment, so that the molten metal in the ladle body can be accurately introduced into the injection port of the mold, and the molten metal can be prevented from spilling outside the mold.

[0015] This utility model utilizes a ladle walking mechanism and a control box to control the position of the ladle outlet. Both are located outside the ladle body and are not directly connected to it, which effectively reduces the probability of damage caused by repeated high and low temperature changes in the ladle, reduces the maintenance frequency of the device, and improves the continuity of the device operation. This ensures the continuous operation of casting and is suitable for widespread application in cast iron casting operations. Attached Figure Description

[0020] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0021] like Figures 1 to 3 As shown, this utility model provides a cast iron casting device, which includes a ladle body 2, a guide frame 1, a ladle walking mechanism, a ladle tilting mechanism 3, and a control box 14. The guide frame 1 covers the mold and has a guide rail 4 at its top, located above the mold. The extension direction of the guide rail 4 is the same as the arrangement direction of the multiple molds, which is used to guide the ladle walking mechanism.

[0022] The ladle walking mechanism includes a ladle mounting frame 5 for mounting the ladle body 2, a set of walking wheels for driving the ladle body 2 to move along the mold arrangement direction, and a servo motor A6 for driving the walking wheels. The connection relationship is as follows: a rotating shaft is provided on the outer surface of the ladle body 2 perpendicular to the outlet. The ladle body 2 is hinged to the ladle mounting frame 5 via the rotating shaft and is located above the mold. The ladle body 2 has the freedom to swing around the rotating shaft. The walking wheels are located at the lower end of the ladle mounting frame 5 and cooperate with the guide rail 4. The walking wheels are connected to the servo motor A6 for transmission.

[0023] The ladle tilting mechanism 3 is mounted on the ladle mounting frame 5. The ladle body 2 is connected to the ladle tilting mechanism 3 by transmission. By controlling the movement of the ladle tilting mechanism 3, the ladle body 2 is tilted at a certain angle, thereby pouring out the molten metal.

[0024] Furthermore, in this embodiment, the control box 14 is located outside the guide frame 1 and includes a PLC controller. The PLC controller is electrically and communicatively connected to the ladle walking mechanism and the ladle tilting mechanism 3. By inputting a control program into the PLC controller and setting the walking increment of the ladle walking mechanism for each movement in the program, the positional difference between the ladle body 2 and the mold injection port caused by the reduction of molten metal and the increase of tilt angle is compensated.

[0025] Furthermore, such as Figure 2 , Figure 3 As shown, the ladle tilting mechanism 3 in this embodiment includes a fixed base 7, a lifting reel 8, a servo motor B9, and a lifting chain 10. The lifting reel 8 is mounted on the ladle mounting frame 5 via the fixed base 7 and bearings. The servo motor B9 is fixed to the fixed base 7 and is connected to the lifting reel 8 for driving its rotation. A lifting lug 11 is provided on the rear side of the ladle body 2 opposite to the outlet. One end of the lifting chain 10 is fixed to the lifting reel 8, and the other end is fixed to the lifting lug 11. The rotation of the servo motor B9 is controlled by a PLC controller to raise the bottom of the ladle body 2, causing the ladle body 2 to swing relative to the rotating shaft, thereby controlling the pouring of molten metal.

[0026] In addition, the liquid outlet of the ladle body 2 is located directly above the line connecting the liquid injection ports of multiple molds. In order to improve the casting efficiency of the ladle body 2, the number of liquid outlets of the ladle body 2 is the same as the number of columns of the multiple molds, so that the ladle body 2 can be tilted once to simultaneously cast into molds in different columns of the same row.

[0027] Furthermore, in order to separate the ladle body 2 from the ladle walking mechanism and the ladle tilting mechanism 3, and reduce the influence of the temperature of the ladle body 2 on both, in this embodiment, the ladle mounting frame 5 includes a mounting base 51 and connecting lugs 52. The walking wheel set is located at the front and rear ends below the mounting base 51, and the connecting lugs 52 are respectively located on the inner side of the middle of both sides of the mounting base 51 and rotate in cooperation with the rotating shaft.

[0028] Furthermore, such as Figure 2 As shown, the walking wheel set in this embodiment includes a driven wheel set 12 and a drive wheel set 13. The driven wheel set 12 is arranged on both sides of the mounting base 51 near the liquid outlet of the pouring ladle body 2, and the drive wheel set 13 is arranged on both sides of the mounting base 51 away from the liquid outlet of the pouring ladle body 2. There are two servo motors A6, which are respectively connected to the two drive wheel sets 13.

[0029] Furthermore, in order to improve the stability of the ladle body 2 during the tilting process, in this embodiment, the number of ladle tilting mechanisms 3 is two sets, which are evenly arranged on the ladle traveling mechanism between the two guide rails 4.
