Description
Technical field
The utility model belongs to Casting Equipment technical field, more particularly, to a kind of casting with Tooth-locked Quick Closure door structure
Make holding furnace.
Background technology
In casting field, when being related to melting, insulation, transfer or the cast of metal bath, it is required for using metal bath
Holding furnace, by taking aluminum alloy low-pressure casting as an example, holding furnace is the pith of low pressure casting system, for Al alloy thermal insulation
Speech, it is basic require to include heat-insulating property and sealing property, sealing and heat-insulating property be directly connected to casting technological parameter can
The stability of control property and temperature of aluminum liquid.Holding furnace needs the pressure for undertaking including rising the gas pressure and gold of liquid pressure maintaining period simultaneously
Category liquid itself static pressure, thus should also have enough intensity.The fire door of holding furnace needs frequency as the critical component of holding furnace
Numerous open and close, is the part for being easiest to damage or produce leakage, thus fire door should also play unlatching, the convenient spirit of closing
It is living, the shortcoming of thermal-insulating sealing effect.Existing low-pressure casting thermal insulation furnace mainly uses traditional handled door structure of band, only
The no more than pressure of 0.1MPa can be born, and the furnace pressure of high boost presence casting machine can reach 0.6MPa, to door structure
New requirement is proposed, while holding furnace furnace wall needs to undertake the immense pressure in stove, thus in the casting process, in order to protect
Card safety, it is necessary to make furnace wall that there is enough intensity, so as to cause the insulation of furnace wall or refractory material thicker, increased cost.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of casting with Tooth-locked Quick Closure door structure protecting
Warm stove.
The complete technical scheme of the utility model includes：A kind of cast insulation stove with Tooth-locked Quick Closure door structure
Cast insulation stove, it is characterised in that door structure includes the fire door located at fire door, fire door is provided with handle, is provided with around fire door
Gear ring, fire door is provided with fire door swing arm, and fire door swing arm is hinged or is pivotally connected with arm shaft, and arm shaft is fixed on fire door support, stove
Fire door band tooth flange is installed on mouthful, fire door band tooth flange have with the intermeshing tooth of gear ring, also including that can drive
Gear ring rotation driving of the fire door with tooth flange rotary, is filled with fire door heat-insulation layer between fire door and flange, flange inner side is provided with lock
Tight block.
The utility model is relative to the advantage of prior art：
1. structure is intermeshed by revolving gear ring/flange to realize to quick locking/openings of fire door and well
Sealing, locking intensity is big, and pressure-bearing level is high, and flexibly, service life is high for simple structure.
2. effectively using low pressure/differential pressure gas pressure is carried out in holding furnace, make fire door supported flange, further increase lock
Tight and sealing property.
3. fire door heat-insulation layer realizes the good heat preservation effect to holding furnace, it is to avoid temperature drop in holding furnace.

Specific embodiment
The utility model is described further with reference to the accompanying drawings and detailed description.
As Figure 1-3, the casting of the disclosed cast insulation stove with Tooth-locked Quick Closure door structure of the utility model
Holding furnace, including body of heater 11, door structure include the fire door 6 located at fire door, and fire door 6 is provided with handle 7, is around provided with gear ring 5,
Fire door is provided with fire door swing arm 4, and fire door swing arm 4 is hinged or is pivotally connected with arm shaft 2, i.e. fire door swing arm 4 can rotate around arm shaft 2,
Arm shaft is fixed on fire door support 1, and fire door band tooth flange 9 is provided with fire door, and the fire door band tooth flange 9 has and gear ring
5 intermeshing teeth, can realize the locking/release of flange 9 and fire door by rotation, and the driving flange 9 of gear ring rotation driving 3 makes it
Rotation, is filled with fire door heat-insulation layer 8 between fire door and flange 9, the inner side of flange 9 is provided with latch segment 10, realizes determining for flange rotary
Position.
Cast insulation stove disclosed in the utility model when in use, injects first with liquid-adding device from fire door to holding furnace
Molten metal, after finishing, makes fire door swing arm 4 be rotated along arm shaft 2 using handle 7, drives fire door 6 to enter fire door band tooth flange 9, with
Rotate it using the driving fire door band tooth of gear ring rotation driving 3 flange 9 afterwards, flange 9 stops the rotation after encountering latch segment 10, now
Tooth on flange is intermeshed with the gear ring 5 on fire door, realizes the closing of door structure, after being pressurizeed to holding furnace, gas
Pressure presses to fire door 6, fire door 6 is tightly pushed down flange 9, furthermore achieved that sealing, can now be cast.After terminating
Insulation heater exhaust release, the driving fire door band tooth of gear ring rotation driving afterwards 3 flange 9 rotates it, makes tooth and fire door on flange
On gear ring 5 no longer engage, fire door swing arm 4 is rotated along arm shaft 2 using handle 7, drive fire door 6 leave fire door band tooth flange
9, the unlatching of fire door is realized, as shown in figure 4, into next working cycles.
Meanwhile, as a kind of preferred scheme, the pipe with hole is additionally provided with holding furnace furnace wall disclosed in the utility model
Road, the pipeline is used to convey gas, and gas is discharged in the space of furnace wall by the hole on pipeline, for increasing in furnace wall
Pressure, can make furnace wall that gas pressure and molten metal itself static pressure in burner hearth are born under less thickness.
The above, is only preferred embodiment of the present utility model, and not the utility model is imposed any restrictions, every
Any simple modification, change and the equivalent structure change made to above example according to the utility model technical spirit, still
Belong in the protection domain of technical solutions of the utility model.
