Description
Technical field
The utility model relates to a kind of magnesium-alloy quantitative charging gear, relate in particular to a kind of magnesium alloy low-pressure casting stove, be applicable to the Mg alloy castings that wall thickness is relatively thicker, weight is bigger, can control the magnesium alloy molten metal when carrying out the low pressure magnesium alloy low-pressure casting, what guarantee molten metal steadily fills solidifying under type and the low pressure.
Background technology
Low pressure casting is to make liquid metals filling die cavity under pressure, to form a kind of method of foundry goods.The low pressure casting stove mainly is made up of sealed crucible, stalk, gas pressure conveying mechanism, control pressurer system etc.Technical process is in the crucible (or hermetically sealed can) of sealing, feeds dry compressed air, and molten metal is under the effect of gas pressure, rise along stalk, enter die cavity reposefully by cast gate, and keep the gas pressure on the liquid level in the crucible, till foundry goods solidifies fully.Remove the gas pressure on the liquid level then, make that not solidified molten metal flows back to crucible in the stalk, again by the cylinder open form and release foundry goods.This technology can be controlled liquid and steadily fill type, can avoid the secondary oxidation with metal liquid of being involved in of gas, owing to be to solidify under certain pressure, can obtain the higher foundry goods of dense structure's performance.Crucible is all needing sealing in each production process but the weak point of conventional low foundry furnace is, so production process can not carry out continuously, just must reopen the crucible seal cover and feed in raw material when molten metal in the crucible uses to a certain degree after.This process is easy to produce oxide inclusion owing to can not realize continuous production in the reinforced process in molten metal, especially all the more so concerning magnesium alloy.Therefore up to the present the low pressure casting of magnesium alloy still is in the development phase always, and the magnesium alloy low-pressure casting stove that can satisfy needs of production is domestic still blank.
Summary of the invention
Technical problem to be solved in the utility model is to overcome present technological deficiency, provides to realize carrying out in the magnesium alloy low-pressure casting continuous charging and the uninterrupted low pressure casting stove of producing; Realize the application of low pressure casting in magnesium alloy is produced.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the magnesium alloy low-pressure casting stove, comprise the resistance heated holding furnace, resistance heated holding furnace internal perisporium is provided with resistance heating body, the technical measures of taking comprise: the inner chamber of resistance heated holding furnace is provided with the power frequency heating furnace of being made up of line-frequency induction coil, yoke, and fusion crucible lies in a horizontal plane in the power frequency heating furnace; The fusion crucible inner chamber is divided into left and right sides two parts through dividing plate; Wherein, the right half cavity is done the low pressure casting chamber, and the left half cavity is done the melting moist closet, about between two part cavitys the valve that opens and closes once connecting rod control that flows through of molten metal connect; Melting moist closet upper end offers charge door, and upper end, low pressure casting chamber is penetrated with stalk and controls the carrier pipe of gas pressure through control device.
For optimizing such scheme, the technical measures of taking comprise:
Between above-mentioned resistance heated holding furnace internal perisporium and the resistance heating body furnace insulation material layer is housed.
Above-mentioned stalk lower port is inserted into the middle and lower part of low pressure casting chamber.
Above-mentioned resistance heated holding furnace is installed on the elevating mechanism that an energy vertical-horizontal moves
Compared with prior art, the inner chamber of the resistance heated holding furnace that the utility model adopts is provided with the power frequency heating furnace of being made up of line-frequency induction coil, yoke, and fusion crucible lies in a horizontal plane in the power frequency heating furnace; The fusion crucible inner chamber is divided into left and right sides two parts through dividing plate; Wherein, the right half cavity is done the low pressure casting chamber, and the left half cavity is done the melting moist closet, about between two part cavitys the valve that opens and closes once connecting rod control that flows through of molten metal connect; Melting moist closet upper end offers charge door, and upper end, low pressure casting chamber is penetrated with stalk and controls the carrier pipe of gas pressure through control device.Continuous charging and uninterrupted outstanding feature of producing have been realized carrying out in the magnesium alloy low-pressure casting.Both reduce complicated operations process and operating personnel, improved safety and the reliability used again.It also has the molten metal scale of construction that accurate control pours into cup simultaneously, avoids the oxidation of molten metal and the outstanding feature that woven hose stops up.
Description of drawings
Fig. 1 is the utility model embodiment overall structure assembling cross-sectional schematic.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Shown in Figure 1, be positioned at the resistance heated holding furnace 1 on the elevating mechanism 13, resistance heated holding furnace 1 internal perisporium is equipped with the furnace insulation material layer, furnace insulation material layer internal perisporium is provided with resistance heating body 2, the inner chamber of resistance heated holding furnace 1 is provided with the power frequency heating furnace of being made up of line-frequency induction coil 7, yoke 8 14, and fusion crucible 3 lies in a horizontal plane in the power frequency heating furnace 14; Fusion crucible 3 inner chambers are divided into left and right sides two parts through dividing plate 3a; Wherein, the right half cavity is done low pressure casting chamber 11, and the left half cavity is done melting moist closet 5, about between two part cavitys the valve 12 that opens and closes once connecting rod 6 controls that flows through of molten metal connect.Melting moist closet 5 as the melting insulation, its upper end offers charge door 4, in process of production can be at any time that the magnesium alloy material is reinforced from charge door, 11 upper ends, low pressure casting chamber are penetrated with stalk 10 and through the carrier pipe 9 of control device control gas pressure, stalk 10 lower port require to be inserted into the middle and lower part of low pressure casting chamber 11.
