Abstract
The utility model discloses a furnace cover of a temperature-preserving furnace of a low-pressure casting machine, which comprises a groove-shaped furnace cover body, wherein the bottom of the furnace cover body is provided with a graphite packing, and the groove of the furnace cover body is internally filled with temperature-insulating material. As the bottom surface of the furnace cover of the temperature-preserving furnace of the low-pressure casting machine is provided with the graphite packing, and the groove of the furnace cover body is internally filled with the temperature-insulating material, and as the graphite packing has better extrusion-resistant and friction-resistant performances than an aluminum silicate asbestos plate, the furnace cover is not easily broken even being frequently opening and closed, thereby prolonging the service life of the temperature-insulating sealing material, improving the production efficiency of the temperature-preserving furnace of the existing low-pressure casting machine, and reduces the cost of low-pressure casting.
Description
Technical field
The utility model relates to a kind of air injection machine holding furnace, relates in particular to a kind of air injection machine holding furnace bell.
Background technology
The general alumina silicate asbestos board that adopts seals between existing air injection machine holding furnace and its bell, plays the effect of sealing and insulation.When interpolation aluminium liquor ratio is frequent, bell needs frequent opening and closing, can cause frequent extruding and friction between alumina silicate asbestos board and air injection machine holding furnace, the bell, cause the breakage of alumina silicate asbestos board very fast, therefore the thermal-insulating sealing material of air injection machine holding furnace bell is shorter service life, have more than is neededly must change several times.And frequent replacing thermal-insulating sealing material can bring a series of problem: as reduced the production efficiency of air injection machine holding furnace, increased the cost of low pressure casting etc.
The utility model content
The utility model provides a kind of air injection machine holding furnace bell, damaged easily with the thermal-insulating sealing material that solves existing air injection machine holding furnace bell, the problem that service life is short, thereby the production efficiency of raising air injection machine holding furnace, the cost of reduction low pressure casting.
For achieving the above object, the utility model provides a kind of air injection machine holding furnace bell, comprises that the bottom surface of the described bell body of bell body that has groove is provided with the graphite packing, is filled with insulation material in the groove of described bell body.
Air injection machine holding furnace bell of the present utility model has groove on the bottom surface of described bell body, and described graphite packing is installed in the described groove, and the part of described graphite packing protrudes in the bottom surface of described bell body.
Air injection machine holding furnace bell of the present utility model also comprises the fixed network that is used for fixing described insulation material in the groove that is installed in described bell body.
Air injection machine holding furnace bell of the present utility model, described insulation material is the alumina silicate asbestos board.
The bottom surface of air injection machine holding furnace bell of the present utility model is provided with the graphite packing, and in the groove of bell, be filled with insulation material, because the graphite packing is with respect to comparatively anti-extruding of alumina silicate asbestos board and rub resistance, even the frequent opening and closing of bell also are not easy to cause its breakage, thereby prolonged the service life of thermal-insulating sealing material, improve the production efficiency of air injection machine holding furnace, reduced the cost of low pressure casting.
Description of drawings
Fig. 1 looks cutaway view for the master of air injection machine holding furnace bell of the present utility model;
Fig. 2 is the upward view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail:
With reference to figure 1 and Fig. 2, air injection machine holding furnace bell of the present utility model comprises the bell body 1 that has groove, on the bottom surface of bell body 1, have the groove 3 of rectangle, the graphite packing 2 of the side's of being equipped with bar shaped in the groove 3, the part of graphite packing 2 protrudes in the bottom surface of bell body 1, be filled with several layers alumina silicate asbestos board 5 in the groove of bell body 1, these alumina silicate asbestos boards 5 are fixing by the fixed network in the groove that is welded on bell body 14, are used to prevent that alumina silicate asbestos board 5 from dropping in the groove of bell body 1.
The bottom surface of air injection machine holding furnace bell of the present utility model is provided with the graphite packing, and in the groove of bell, be filled with insulation material, because the graphite packing is with respect to comparatively anti-extruding of alumina silicate asbestos board and rub resistance, even the frequent opening and closing of bell also are not easy to cause its breakage, thereby prolonged the service life of thermal-insulating sealing material, improve the production efficiency of air injection machine holding furnace, reduced the cost of low pressure casting.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
