Description

Technical Field

[0001] The utility model relates to the technical field of mouth mold firing, in particular to a mouth mold firing device with uniform heating. Background Art

[0002] When manufacturing the compressor balance block, first use a wax injection machine to make the wax block of the balance block, then connect multiple wax blocks together, and then apply slurry (white sand) multiple times and dry them into a semi-finished mouth mold. Then put the semi-finished mouth mold into a firing furnace and burn it into a mouth mold. During the firing, the wax material flows out due to the heat to form a mold with only one entrance. After taking it out and waiting to cool, molten iron is added to the inside of the mouth mold. After cooling into a semi-finished balance block, it will be put into the firing furnace again and heated until the inside is completely melted. Then take out the mouth mold and cool it. Finally, break the mouth mold and take out the balance block inside for fine processing.

[0003] When the firing furnace heats the mouth mold, the furnace mouth of the firing furnace is sealed by the sealing door, but the sealing door moves up and down, so there is a gap between the sealing door and the firing furnace. During the firing process, the heat inside the firing furnace will diffuse outward from the gap, causing the temperature of the external air to rise. When the operator is in a high temperature environment for a long time, it will affect the operator's health. Therefore, the present application provides a mouth mold firing equipment with uniform heating to meet the needs. Utility Model Content

[0016] Compared with the prior art, the utility model has at least the following beneficial effects:

[0017] In the above scheme, by setting the slide groove, round shaft, upper extrusion block and lower extrusion block, when the hydraulic cylinder drives the sealing door to move downward, the sealing door drives the round shaft to slide in the slide groove, and the bottom of the slide groove is an inclined surface offset toward the firing furnace. Therefore, the round shaft moves along the inclined surface of the slide groove, and the round shaft drives the bottom of the sealing door to move toward the firing furnace, so that the sealing door and the firing furnace fit more tightly. Secondly, the upper extrusion block squeezes the lower extrusion block, and the lower extrusion block moves toward the firing furnace. The lower extrusion block drives the sealing door to move toward the firing furnace through the connecting block, so that the top of the sealing door is completely fitted to the surface of the firing furnace. At this time, the firing furnace and the sealing door are tightly fitted, heat cannot diffuse outward from the furnace mouth, and the temperature outside the firing furnace will not be too high, thereby protecting the health of the operators.
