Description

Technical Field

[0001] The utility model belongs to the technical field related to casting equipment processing, in particular to a device for removing iron sticking in a sand mold box of a brake drum molding pouring line. Background Art

[0002] The brake drum is a friction pair of the drum brake. In addition to the strength and rigidity required as a component, it should also have the highest and most stable friction coefficient, as well as appropriate wear resistance, heat resistance, heat dissipation and heat capacity. When it is produced, it needs to be produced by casting equipment. In the automatic production line for casting and pouring, since the casting molding and pouring processes are automatically controlled by the program, it is inevitable that the casting molten iron will splash or overflow during casting due to the accuracy of equipment positioning, casting model replacement and pouring port filter blockage, thus sticking to the sand mold box surface. However, since the sand mold box with residual iron is not conducive to the sand mold and circulation operation of the automatic molding line, especially the corresponding sand mold box side, it is necessary to remove the sticky iron on the sand mold box through a sticking removal device, but it still has the following disadvantages in actual use:

[0003] When the device for removing the sticking iron from the sand mold box of the brake drum molding casting line is working, it is troublesome to limit the position of the sand mold boxes of different sizes when removing the sticking iron from different surfaces;

[0004] When the device for removing sticked iron from the sand mold box of the brake drum molding casting line is working, when removing the sticked iron from the sand mold boxes on different surfaces, grinding interference will occur on the adjacent surfaces. During the removal, the adjacent surfaces are easily interfered by the grinding and are easily interfered during use. Utility Model Content

By arranging a bottom support plate, a support box and a push plate, the utility model solves the problem that the device for removing iron sticking to the sand mold box of a brake drum molding casting line is troublesome to limit sand mold boxes of different sizes during operation, and adjacent surfaces are easily interfered when removing iron sticking.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a device for removing iron stuck on a sand mold box of a brake drum molding casting line, comprising a bottom support plate, a support box and a push plate, wherein a support box is fixed at the top center of the bottom support plate, a fixed block is fixed at the top center of the support box, one electric push rod is fixed on four outer surfaces of the fixed block, and a push plate is arranged at four edges of the top of the bottom support plate, two electric push rods are symmetrically fixed along a vertical center line at the lower part of the push plate away from one side of the support box, and a fixed plate is commonly fixed at one end of the two electric push rods fixed on each of the push plates away from the push plate, when working, the support box and the push plate are supported thereon by the bottom support plate, and when the support box is working, a corresponding sand mold box of a drum molding casting line is supported thereon, and when the push plate is working, a corresponding grinding disc is supported thereon.

[0008] Furthermore, a limiting plate is fixed in the middle of the four vertical surfaces of the bottom support plate, a hydraulic cylinder is fixed in the top center of the bottom support plate, a hydraulic rod is movably connected in the hydraulic cylinder, the bottom support plate limits the push plate through the limiting plate, and the hydraulic rod is driven to rise and fall through the hydraulic cylinder.

[0009] Furthermore, a through hole is provided at the center of the top of the support box, and a through hole is also provided at the top of the fixed block, and the support box and the fixed block are movably connected to the hydraulic rod through the through hole.

[0010] Furthermore, the hydraulic rod is movably connected in the through holes in the support box and the fixed block, and a push plate 1 is fixed to the top of the hydraulic rod. When the push plate 1 is driven by the hydraulic rod, the corresponding drum-shaped casting line sand mold box is supported at a corresponding height.

[0011] Furthermore, the telescopic end of the electric push rod 1 is movably connected in the support box, and a push disk 2 is fixed to the telescopic end of the electric push rod 1. The electric push rod 1 limits the sand mold box of the drum molding casting line by driving the push disk 2.

[0012] Furthermore, a driving motor is fixed to the upper part of each pushing plate away from the supporting box, the output shaft of the driving motor is movably connected through the pushing plate, and a grinding disc is fixed to one end of the driving motor output shaft close to the supporting box, so that the grinding disc is polished when driven by the driving motor.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that it is troublesome to restrict sand mold boxes of different sizes when a device for clearing iron sticking to a sand mold box of a brake drum molding casting line is working by arranging a bottom support plate and a support box. The hydraulic cylinder is started, and the hydraulic cylinder drives the hydraulic rod to rise. When the hydraulic rod rises, the push plate one is raised to push the sand mold box of the drum molding casting line to a suitable height, and then the electric push rod one is started, and the electric push rod one drives the push plate two, so that the push plate two is squeezed onto the sand mold box of the drum molding casting line, so that the sand mold box of the drum molding casting line is well restricted on the support box, making it more convenient to restrict sand mold boxes of different sizes.

[0015] The utility model solves the problem that the device for removing stuck iron from the sand mold box of the brake drum molding casting line is easily disturbed when removing stuck iron from adjacent surfaces during operation by arranging a bottom support plate and a push plate. The driving motor drives the grinding disc to rotate. When the grinding disc is driven to rotate by the driving motor, when the grinding disc contacts the sand mold box of the drum molding casting line, the stuck iron on the outer surface of the sand mold box of the drum molding casting line is polished and removed. After the two push plates are released, the remaining two push plates are started, so that after the operation is performed, the stuck iron on the outer surface of the sand mold box of the drum molding casting line is polished and removed, and then the push plate is released, and the electric push rod 1 is started, so that the push plate on the electric push rod 1 releases the sand mold box of the drum molding casting line, so that the adjacent surfaces are less likely to be disturbed when removing stuck iron during operation, and are less likely to be disturbed while ensuring efficiency during operation.
