There is a problem with this method of casting pig iron blocks: the iron trough or pouring gate continuously and stably pours molten iron on the iron mold line of the cast iron machine, which is prone to splashing molten iron at the intersection of the two iron molds, which not only wastes molten iron, but also the splashing iron beans and iron slag will affect the moving parts of the cast iron machine and cause mechanical failure; the splashing of molten iron will also cause certain safety hazards. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail in conjunction with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. The technical solutions of the present invention are described in detail below in conjunction with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0022] Example 1

[0023] like Figure 1 and Figure 2 As shown, it is a swing casting device of a pig iron casting machine, the casting machine includes a movable continuous iron mold 12, a casting machine wheel 11 is arranged at the bottom of the continuous iron mold 12; and a molten iron chute 1 located above the continuous iron mold 12; the continuous iron mold 12 is a continuous groove structure, and there are convex ridges at the connection between the iron molds. The conventional casting method is to continuously cast the molten iron in the molten iron chute 1. When pouring at the convex ridge position, the problem of molten iron splashing will occur.

[0024] In order to solve the problem of molten iron splashing, a swing pouring device is installed between the continuous iron mold 12 and the molten iron chute 1.

[0025] The swing casting device includes a wheel drag arm 5, a rotating wheel 10, a swing arm 4 and a swing casting trough 2; the trough mouth of the molten iron trough 1 is located directly above the swing casting trough 2. One end of the wheel drag arm 5 is axially connected to the rotating wheel 10, and the other end is hinged on the drag arm fixed shaft 6; the rotating wheel 10 is located on the surface of the continuous iron mold 12, and is used to roll along it as the continuous iron mold 12 moves; the front end of the swing arm 4 is flexibly hinged to the wheel drag arm 5 at the second hinge connection 7. The middle part of the swing arm 4 is hinged to the arm fixed shaft 8, and is used to swing with the arm fixed shaft 8 as the center of the circle; the swing casting trough 2 is hinged to the casting trough fixed shaft 3, and the end of the swing casting trough 2 away from the pouring mouth is flexibly hinged to the rear end of the swing arm 4. The swing casting trough 2 performs intermittent casting under the action of the swing arm 4; wherein, the length of the swing arm 4 satisfies that when the rotating wheel 10 is located at the bottom of the groove of the continuous iron mold 12, the pouring port of the swing casting trough 2 is located above the subsequent iron mold groove of the continuous iron mold 12 and is in a casting state.

[0026] The runner drag arm 5 and the swing arm 4 can be made of arc-shaped steel plates. The connection hole at the second hinge connection 7 is a wide slot through hole with a certain width, so as not to restrict the movement of the swing arm 4. The drag arm fixed shaft 6, the arm fixed shaft 8 and the casting trough fixed shaft 3 are fixed above the continuous iron mold 12 through the cast iron machine base frame.

[0027] Specific operating principle: the continuous iron mold 12 moves forward continuously with the operation of the cast iron machine line. The rotating wheel 10, under the drag of the rotating wheel drag arm 5, makes an up and down arc movement along the surface of the continuous iron mold 12 with the drag arm fixed axis 6 as the center. The swing arm 4 swings with the arm fixed axis 8 as the center. When the rotating wheel 10 enters the groove, the front end of the swing arm 4 is pressed down and the rear end is tilted up, the pressure plate 13 is released, and the pouring port of the swing casting trough 2 is tilted downward to align with the groove for pouring; on the contrary, when the rotating wheel 10 moves to the convex ridge, the front end of the swing arm 4 moves up and the rear end moves down, the pressure plate 13 is pressed down, and the pouring port of the swing casting trough 2 is temporarily tilted upward, and the pouring on the subsequent convex ridge is stopped to reduce the splashing of molten iron.

[0028] Example 2

[0029] like Figure 3 As shown, the structure of this embodiment is the same as that of the embodiment 1, except that the rear end of the swing arm 4 and the swing casting trough 2 are flexibly hinged at the first hinge connection 9 at the linkage part between the swing arm 4 and the swing casting trough 2. The connection hole at the first hinge connection 9 is a through hole with a certain width, so as not to restrict the movement of the swing casting trough 2; when the rear end of the swing arm 4 is pressed down, the swing casting trough 2 is tilted up, and when the rear end of the swing arm 4 is moved up, the swing casting trough 2 is poured downward.

[0030] The swing casting device with the rotating wheel drag arm 5 structure of embodiments 1 and 2 is suitable for a continuous iron mold 12 with a deeper groove. The rotating wheel drag arm 5 will give a drag force to the rotating wheel 10, so that the rotating wheel 10 can move up and down more smoothly and is not prone to jamming.

[0031] Example 3

[0032] like Figure 4 As shown, it is a pig iron casting machine swing casting simplified structure device, this swing casting device removes the structure of the trailing arm fixed shaft 6 and the rotating wheel trailing arm 5, this structure is simpler, suitable for a continuous iron mold 12 with a shallow groove, the rotating wheel 10 is directly connected to the front end of the swing arm 4, and the rear end of the swing arm 4 is flexibly hinged to the swing casting trough 2 at the first hinge connection 9. The rest of the structure is the same as that of Example 2.

[0033] The above content is a further detailed description of the present invention in combination with a specific preferred embodiment. It cannot be determined that the specific embodiments of the present invention are limited to this. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the present invention, which should be regarded as belonging to the present invention and the scope of patent protection determined by the submitted claims.
