Description
Technical field
The utility model is related to a kind of smelting apparatus, specifically a kind of diecasting alloys twin furnace produced for alloy pressuring casting
Smelting apparatus.
Background technology
Die casting (full name：Compression casting), refer to molten alloy filling mold cavity under high pressure, high-speed condition, and
The casting method being cooled and shaped under high pressure.With developing rapidly for the fields such as auto industry, product is to large quantities of in modern manufacturing industry
Quantization, complication, precise treatment, lightweight, energy-saving, the requirement of greenization manufacturing technology are improved constantly, and die casting turns into casting
Non-ferrous alloy precision parts forming technique most widely used in technique, with the fastest developing speed.Clean liquid metal is to obtain
The precondition and guarantee of high-quality die casting, therefore, in fusing and cast, melt obtains totally enclosed type protection to prevent melt to be mingled with
Enter die casting die cavity with gas, it is to avoid cause cast properties reduction very because being mingled with the various defects produced with gas in die casting
To scrapping.
In face of Die Casting high efficiency, high-precision development trend, need to solve the technical problem of quantitative pouring in die casting,
Improve the problem of gentle control quantitative accuracy of Automated water of quantitative pouring process is in the urgent need to address in producing.Traditional hand
Work topping is easiest to realize, quantitative relatively accurate, but manual topping labor strength is big, it is relatively hazardous to operate；Manipulator topping
It is quantitative accurate although automation can be realized, labor strength reduction, identical with manual topping, manipulator topping is exposed
Carry out in atmosphere, liquid metal is directly contacted with air, cause the oxide inclusion content of metal liquid to raise, so as to drop
Low casting quality, especially produces especially prominent to the magnesium alloy pressure-casting for being also easy to produce oxide inclusion.Holding furnace is closed by constant displacement pump
The diecasting alloys liquid of constant basis, which is added in the gate spool of heating, under golden liquid level is poured into a mould, and not only diecasting alloys liquid was being conveyed
Completely cut off the contact with air in journey, and bath surface is not destroyed in holding furnace, so as to effectively overcome manual topping
The problem of diecasting alloys liquid brought with manipulator topping is also easy to produce oxide inclusion, closes so as to ensure that into die-casting die intracavitary
The cleanliness factor of golden liquid.Conventional constant displacement pump has at present, and conventional constant displacement pump has pulsometer, piston pump, centrifugal pump, vane pump, spiral shell
Bar pump, electromagnetic pump etc..
There must be the optimum temperature range that heating, heat-insulation layer make it operationally be preheating to requirement on gate spool, to prevent
Diecasting alloys liquid occurs excessive temperature drop even frozen plug depositing when flowing through gate spool.Aluminium alloy is in die casting in gate spool
Production should be able to be flow back into holding furnace completely when stopping work, should be at during Die Casting the state that can pour into a mould at any time and with compared with
Short flow reduces the heat loss in transmit process.
When Die Casting is stopped work, die casting workman answers fast quick-detach gate spool and the aluminium alloy in pipe is backed into guarantor by hand
In warm stove, but the general fusing point of diecasting alloys is relatively low, and gate spool preferably must be held in heated condition, so undoubtedly increase operation
The difficulty and danger of workman；If interrupting heating, because gate spool is connected with constant displacement pump, it is difficult to complete in a short time, residual
Aluminium alloy in gate spool solidifies in pipe, causes diecasting alloys liquid gate spool not use.To be solidified in cleaning gate spool
Aluminium alloy it is not only time-consuming, and greatly reduce the service life of gate spool.
For the ease of Die Casting, when traditional holding furnace is installed in do not consider that its alloy liquid level is fed with die casting machine
The position relationship of cylinder, gate spool is generally to tilt to install, and causes to pour into a mould within the time for not conveying aluminium alloy during Die Casting
Pipe highest position is in hollow state.It can thus be appreciated that, on the one hand, during Die Casting, aluminium alloy is in course of conveying by hollow
Gate spool extreme higher position when not only the flowing of pipe inner metal liquid body unstable, longer flow is increased to heat in transmit process
Loss, and remain in after gate spool highest position aluminium alloy flows through the aluminium alloy of inside pipe wall can be with both sides aluminium alloy in pipe
Oxidation reaction and deposition oxide occur for the gas separated out in face, and frequently oxide deposition is easily caused cast blockage.It is another
Aspect, when Die Casting is stopped work, the alloy at cast gate wants to refund the extreme higher position that holding furnace must first go through gate spool, will
The difficulty that aluminium alloy in pipe is backed in holding furnace completely is also very big.
