Abstract
Disclosed is a furnace door protecting device for a holding furnace of a low-pressure casting machine. The device is composed of an inner frame and an outer frame, the inner frame and the outer frame are identical with a furnace door in shape, size of he inner frame is smaller than that of the furnace door of the holding furnace, size of the outer frame is not larger than that of a cover sealing part of the furnace door of the holding furnace, and the outer frame and a furnace body are connected through four high strength bolts which are in four directions respectively. After the protection device of the structure is added, damage to castables due to frequent opening and closing of the furnace door can be reduced, the furnace door even if being damaged can be detached to be maintained, and accordingly the device is more applicable to casting of aluminum wheels.
Description
Technical field
The utility model relates to low pressure casting equipment field, relates in particular to a kind of low pressure casting machine holding furnace fire door protective device.
Background technology
Low pressure casting is the most frequently used forging type of current aluminum wheel of vehicle, air injection machine is collection pneumatic control system, control system, hydraulic system, the electromechanical integration equipment that mechanical system is integrated, holding furnace is wherein important building block, aluminium liquid adds holding furnace to realize in mold cavity through stalk to fill type and solidifies, thereby complete the shaping of casting aluminum wheels blank, general holding furnace is 800-1200 kilogram, aluminium liquid life cycle is 3-4 hour, therefore need in process of production continual interpolation aluminium liquid, the fire door of holding furnace needs switch continually, now the fire door of holding furnace and body of heater is integral type casting complete, switch easily causes shock to fire door frequently, thereby being come off, castable affects furnace temperature and the sealing of holding furnace, if changed, need integral body to pull down cast again, not only waste time and energy, and have a strong impact on normally carrying out of production.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes existing holding furnace fire door design, and a kind of quick detachable holding furnace fire door with keeping in repair is provided.
The concrete scheme of realizing above technology is: a kind of low pressure casting machine holding furnace fire door protective device, this device is by inside casing, two parts of housing form, wherein the shape of inside casing and housing and fire door coincide, inside casing size is less than holding furnace fire door, housing size is not more than holding furnace stove face plate sealing position, housing is connected with 4 high-strength bolts with body of heater, one, each direction of high-strength bolt, installed additional after the protective device of above structure, can reduce the damage due to the fire door castable that switch causes frequently, even if damaged fire door also can disassemble and keep in repair simultaneously, therefore the casting that is more suitable for aluminum vehicle wheel is used.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1; a kind of low pressure casting machine holding furnace fire door protective device; this device consists of housing 1, inside casing 2; inside casing 2 is less than holding furnace fire door; housing 1 is not more than holding furnace stove face plate sealing position; housing 1 links by 4 high-strength bolts 3 and body of heater, and fire door 4 is the position that claws of the interpolation of aluminium liquid and slag, and this device has anticollision, easily changeable feature.
