The distance between the outer wall of the casting mold and the inner wall of the steel slag pot is 8 - 10 cm. The structure of the casting mold is that a circular ring in the shape of a regular quadrangular pyramid connected as a whole is arranged on the upper opening of an inverted quadrangular pyramid-shaped box body, and lifting lugs are evenly fixed on the outer wall of the circular ring. The structure of this utility model is reasonable, which can improve the construction speed, ensure the uniform thickness of the refractory material cast on the inner wall of the slag pot, ensure the service time of the slag pot, reduce the labor intensity of workers, and improve work efficiency.

[0003] However, during the use of the existing casting molds, the distance between the refractory material and the mold is not easy to control, which easily leads to a thicker refractory material on one side and a thinner refractory material on the other side, affecting the quality of the dried refractory material. And when adding refractory material into the gap, air bubbles are likely to remain inside the gap, resulting in a reduction in the strength of the refractory material. Therefore, it is necessary to improve the existing technology. Summary of the Utility Model

A plurality of uniformly distributed ventilation holes are formed in the upper end inside the mold cover, and the ventilation holes can discharge the gas inside the mold cover.

[0009] Preferably, the upper end of the feeding pipe is threadedly connected with an end cover, and the sealing plug is slidably connected to the inner wall of the feeding pipe, and the sealing plug can seal the outlet of the feeding pipe.

[0010] Preferably, one end of the second spring is fixedly connected to the installation strip, and the other end of the second spring is fixedly connected to the connecting nail. The second spring can increase the movement resistance of the connecting nail through elastic force.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By adding structures such as a frame, a limit seat and a sliding rod to the mold cover, during use, the mold cover can be installed inside the frame through the limit seat, and the workpiece shell can be squeezed between the mold cover and the frame, so as to effectively ensure the concentricity between the mold cover and the workpiece shell, and avoid uneven thickness of the refractory material layer.

[0013] 2. By adding structures such as a feeding pipe, a sealing plug and ventilation holes to the mold cover, during the process of feeding the gap between the mold cover and the workpiece shell, it is necessary to feed through the feeding pipe into the gap. During the feeding process, the feeding pressure needs to be greater than the elastic force of the second spring, so as to effectively increase the feeding flow rate. The flow rate can effectively discharge the gas inside the gap, and effectively avoid the generation of bubbles inside the refractory material. BRIEF DESCRIPTION OF THE DRAWINGS
