Below for an embodiment, as the description of feature of the present invention.Fig. 4 is according to the present invention, the last pseudosection of furnace construction.In Fig. 4, molten soup 52 contains in a molten soup crucible.Around the molten soup crucible some heaters are arranged, but, do not need heater in one side that gooseneck 58 is arranged.And in molten soup crucible, be provided with some assemblies and comprise Fig. 2 A as described above, gooseneck 58 structures are with the molten soup propulsive mechanism 58 ' of gooseneck 58 base portions.Gooseneck 58 constitutes a molten soup injection unit with molten soup propulsive mechanism 58 '.About the part of gooseneck 58, traditionally as Fig. 2 A, molten soup is conducted to die unit 50, causes the difficulty of die casting easily because of cooling.The present invention causes the problem of cooling in order to solve molten soup by gooseneck 58, around gooseneck 58, is equiped with a heat retainer 70, for example is the heater of middle cycle, is looped around on the gooseneck 58.So, when molten soup passes through gooseneck 58, can obviously not cool off, carry out die casting smoothly to keep.
In addition, in molten soup crucible, also can comprise a pumping 72 is set.Pumping 72 has an outlet 74.Drive molten soup 52 by pumping 72, its direction according to outlet 74 is promoted.So, molten soup 52 causes molten soup 52 circulating in crucible by the driving of pumping 72, so can promote the even of molten soup 52 temperature.With the example that is set to of heater among Fig. 4, it is three limit having heaters only.Molten soup 52 is near this three limit, and its temperature is higher naturally.And one side of gooseneck 58 is arranged, because of there not being the setting of heater, its temperature can be lower.Therefore, pumping 72 can be arranged at one side of having heaters, and outlet 74 is towards the lower one side of temperature.Therefore because the effect of pumping 72 can make molten soup 52 temperature be tending towards a distribution more uniformly.
As for the position of pumping 72,, can change according to actual design with the direction of outlet 74.For example, if the volume of smelting furnace is less, the position of pumping 72 also can be arranged at the middle part.
In addition, gooseneck 58 of the present invention has the insulation of heat retainer 70, allows the length of gooseneck 58 to increase, one side it also can suitably increase by a heater in gooseneck 58.Yet, if wish that the length of gooseneck 58 is constant, and do not set up heater, the effect of pumping 72 this moment is just more obvious.
Then about the consume problem of protective gas, the present invention proposes to adopt the mode of sliding door to solve.In Fig. 4, the loam cake of molten soup crucible has an opening 62, is the input port of material piece 68.Material piece 68, for example magnesium alloy ingot is dropped in the crucible by slide plate 66, is fused into soup 52 by heater.One sliding door 78 utilizes the mechanism of sliding, and can close or open opening 62.
Fig. 5 A is according to the present invention, the structure side profile of sliding door.And Fig. 5 B is according to the present invention, the structure top view of sliding door.In Fig. 5 A-Fig. 5 B, sliding door 78 is installed on a pair of slide rail 76.One door knob 80 is arranged on the sliding door 78.Sliding door 78 moves along slide rail 76, to close opening 62.Between molten soup 52 surfaces and cover plate, be filled with protective gas.When material piece 68 was desired to be dropped into, sliding door 78 slided traversing.Because the mechanism of sliding, the flow-disturbing that it more can not cause protective gas causes the loss of protective gas.
According to above-mentioned, the present invention carries out effectiveness analysis to traditional furnace construction, and finding has multinomial shortcoming, in addition at shortcoming, proposes some modes, can solve the shortcoming that is proposed by the present invention at least.It is as follows that the present invention has multiple advantages at least:
