Technical field
The utility model relates to a kind of die assembly, relates in particular to a kind of die assembly in order to test heat release welding compound molten metal flow.
Background technology
Along with economic development, the paces of power grid construction are accelerated gradually, and in power grid construction, the grounding net of transformer substation reliability is most important for the safe operation of electrical network, and therefore, the copper covered steel grounded screen of a new generation just progressively replaces hot-galvanized steel grounded screen.The installation position multidigit of grounded screen adopts arc welding, gas welding that the shortcoming that the equipment carrying is inconvenient, need auxiliary facility is all arranged in field environment.So the heat release welding is a kind of suitable welding manner, and the joint of copper covered steel grounded screen is copper, steel composite material, heat release welding in the past is often at copper-copper sleeve, steel-steel joint.And needing the development of new welding compound for the welding of copper-steel composite material joint, the following factor of the welding quality of novel welding compound is relevant, i.e. molten metal flow.Formula development does not in the past all have special-purpose test mould, and test method is extensive simple and crude, and is poor for the reflection intuitive of above-mentioned factor.Therefore, need a kind of test mould to test the center tap quality by the visualize welding compound, in order to carry out the welding compound design.
The utility model content
In order to solve the problem of no special-purpose test mould in the existing formula test, the utility model provides a kind of copper covered steel joint heat release welding compound test mould assembly that carries out specially, and this die assembly can be verified the motlten metal flowability.
Welding mould assembly in the utility model is made of two parts: fusion crucible parts and fluidity test parts.
The fusion crucible parts are the key reaction parts, and welding compound reacts therein and forms molten metal liquid.
The fluidity test parts are test motlten metal mold filling ability parts, and the motlten metal flowability is good more, and the mold filling ability is strong more, and liquid metal flows in the liquation chamber apart from big more, and the unnecessary gas in the mould can be got rid of by the vent port of liquation chamber end.
Concrete technical scheme is as follows:
This die assembly comprises fusion crucible parts and fluidity test parts two parts.Described fusion crucible parts comprise a reaction chamber.Described fluidity test parts comprise a vent port that is used for the sprue gate that is connected with the reaction chamber of fusion crucible parts, the liquation chamber that is connected with the sprue gate and is connected with liquation chamber end.The fluidity test parts are last lower open die, and fluidity test parts die sinking face passes the liquation chamber.
Reaction chamber in the described fusion crucible parts comprises reaction chamber upper cone and reaction chamber lower cone two parts from top to bottom successively.
The cone angle of the reaction chamber upper cone in the described fusion crucible parts is less than the cone angle of reaction chamber lower cone.
The bottom at the sprue gate in the described fluidity test parts is provided with the dashpot of taper.
Liquation chamber in the described fluidity test parts be shaped as circular arc.
The utlity model has following advantage:
1) the fluidity test parts can carry out the test of molten metal flowability and mold filling ability at different flux constituents, have improved the accuracy and the test efficiency of test greatly;
2) the utility model is divided into fusion crucible parts and fluidity test parts.Two assemblies can be able to not changed during the warranty test accuracy for the fluidity test that is easier to wear and tear, and the fusion crucible parts can continue to use, and reduce use cost.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing 1～9:
As Fig. 8, shown in Figure 9, present embodiment comprises two parts: fusion crucible parts and fluidity test parts.
The structure of fusion crucible parts such as Fig. 1～shown in Figure 3, the fusion crucible parts are mainly a reaction chamber.Reaction chamber comprises reaction chamber upper cone 1 and reaction chamber lower cone 3 two parts from top to bottom successively, and the cone angle of reaction chamber upper cone 1 is less than the cone angle of reaction chamber lower cone 3.
The structure of fluidity test parts comprises a vent port 6 that is used for the sprue gate 8 that is connected with the reaction chamber of fusion crucible parts, the liquation chamber 7 that is connected with the sprue gate and is connected with liquation chamber end as shown in Figure 4 to 7.The bottom at sprue gate 8 is provided with the dashpot 11 of taper, liquation chamber 7 be shaped as semicircle.The fluidity test parts are last lower open die, and fluidity test parts die sinking face 10 passes liquation chamber 7.
