Description

Technical Field

[0001] The utility model relates to the field of iron casting machines, in particular to a slurry supply device for iron casting machines. Background Art

[0002] The iron casting machine is the core equipment for producing cast iron blocks. The molten iron flows into the cast iron mold of the iron casting machine through the molten iron flow trough. The cast iron mold moves slowly under the action of the chain belt. After the iron block cools down, it falls out of the cast iron mold at the bend of the chain belt and falls off to the stacking yard under the action of gravity. According to the production process, in order to facilitate the demoulding of the iron block, it is necessary to spray a layer of lime slurry in the cast iron mold before receiving the molten iron. The existing spraying mechanism uses a nozzle to spray lime slurry into the cast iron mold. The disadvantages of this are that the nozzle is easily clogged, affecting the operation of the iron casting machine. Secondly, in order to ensure that the inner wall of the cast iron mold is completely sprayed, the spraying area of the nozzle is large, which will cause the chain belt outside the cast iron mold and other cast iron mechanism components to be stained with a large amount of lime slurry, which will not only cause waste of lime slurry but also easily corrode and damage the iron casting machine. In summary, a slurry supply mechanism for a iron casting machine that does not use nozzle spraying is needed. Utility Model Content

[0016] like Figure 1 and Figure 2As shown, a slurry supply device for a cast iron machine described in this embodiment includes a lifting platform 1, a transverse platform 2, a slurry bottom shell 3 and a cast iron mold 4 arranged in sequence from bottom to top; the lifting platform 1 is driven by a hydraulic cylinder 5 and a guide slide bar 6 is provided on the left and right sides of the lifting platform 1, the lifting platform 1 is further fixed with two side plates 7, two slide bars 8 are arranged parallel between the two side plates 7, a slider 9 is fixed on the transverse platform 2 and matched with the slide bar 8, and a compression spring 10 is sleeved on the slide bar 8 between the slider 9 and the side plate 7. The two compression springs 10 have the same specifications. The function of the two compression springs 10 is to enable the slurry bottom shell 3 to automatically return to the center when it is not subjected to horizontal external force;

[0017] The slurry bottom shell 3 has an upper opening that cooperates with the cast iron mold 4. A fluororubber pad is provided at the upper opening of the slurry bottom shell 3 to ensure the sealing between the slurry bottom shell 3 and the cast iron mold 4.

The upper opening of the slurry bottom shell 3 is buckled at the lower opening of the cast iron mold 4, and the ball head 14 closes the leakage hole 11. The slurry supply pump drives the lime slurry into the enclosed space of the slurry bottom shell 3 and the cast iron mold 4 through the slurry supply hose 15. The inner wall of the cast iron mold 4 is fully infiltrated with lime slurry. The beating process takes less than 3s. During this process, the cast iron mold 4 is in a slowly moving state. The slurry bottom shell 3 moves with a small stroke driven by the friction of the cast iron mold 4 and the permission of the transverse platform 2, and then starts to discharge the slurry. The hydraulic cylinder 5 retracts, and the lifting platform 1, The lateral movement platform 2 and the slurry bottom shell 3 are both lowered, and the lateral movement platform 2 and the slurry bottom shell 3 return to the center, the ball head 14 leaves the upper side of the leakage hole 11, and the lime slurry flows into the slurry receiving groove 16 below through the leakage hole 11 and the edge of the slurry bottom shell 3 and then is discharged into the slurry storage tank through the slurry discharge port 17.
