It falls into, quality requirement cannot be reached；Mold average life span made of graphite be 50~100 joint made by flame weldings, if weldment by
Welding mould is closed in the case of power, weldment hole is possible to stress damage, allow for that weld mold all replaces in this way at
This is relatively high.
Utility model content
The purpose of this utility model is that solve existing exothermic mold service life it is low, it is impaired after replacement cost is high asks
Topic provides a kind of exothermic welding mould for improving the easily worn part service life, being easily changed after each component is impaired.
The purpose of this utility model and its technical problem is solved using following technical scheme to realize.
According to the utility model proposes a kind of exothermic welding mould, including reaction mould, welding mould, the reaction mould opens up
The lower part of reactive tank with upper cover, reactive tank is connected to the first diversion trench, and the lower end for reacting lower part the first diversion trench of correspondence of mould is set
Set with react mould integrally connected, downward projection of, lower part be small end frustum cone structure, the first diversion trench, which extends downwardly, to be communicated to
The lower face of frustum cone structure；The welding mould includes fastening upper welding mould, the lower welding mould being integrated, the top pair of upper welding mould
Frustum cone structure is answered to open up the mating groove of circular platform type, the lower part of upper welding mould opens up the upper welding slot for exothermic weld welded part,
The second diversion trench being connected to the first diversion trench is opened up between mating groove and welding slot；The top of lower welding mould opens up and upper welding
Weldment slot of the slot cooperation for the lower welding slot of exothermic weld welded part and for placing welded part；The reaction mould and molten
Mould is connect to be made by graphite material, react the lower side surfaces of mould, the side surface of upper welding mould, lower welding mould side surface and
The steel plate layer of the bottom surface fitting setting protection of lower welding mould.
It the purpose of this utility model and solves its technical problem following technical measures also can be used to further realize.
Preferably, a kind of exothermic welding mould above-mentioned, the weldment slot corresponds to company at the port of lower welding mould side surface
Connect welded part fixing device, welded part fixing device be drop-over on the outside of weldment slot, steel plate layer with lower welding mould side surface
The steel-tube construction of connection, adjustment bolt of the setting for assist compression welded part, the downside of steel pipe on the upside tube wall of steel pipe
Connection reinforcement plate muscle between tube wall and the steel plate layer of lower welding slot side surface.
Preferably, a kind of exothermic welding mould above-mentioned, the port of the weldment slot is rectangular, and welded part fixing device is
Rectangular steel tube structure, rectangular steel tube is along 2~3 times that the length that lower welding mould extends outward is the rectangular port length of weldment slot.
Preferably, a kind of exothermic welding mould above-mentioned, latch hook is set in the steel plate layer of the reaction mould side surface, it is upper molten
Connect the lock that locking latch hook is correspondingly arranged in the steel plate layer of mould side surface；The exothermic welding mould further includes being provided with two groups to put down
It is opened up on the side wall of the clamping device of capable clip, the reaction mould and the lower any homonymy of welding mould for being inserted into four folders of clip
Tieholen.
Preferably, a kind of exothermic welding mould above-mentioned, the height of the frustum cone structure of reaction mould lower part is that upper welding mould is high
The 1/2~2/3 of degree, the end diameter of the frustum cone structure of reaction mould lower part are 2~2.5 times of the first diversion trench diameter；The steel
The thickness of plate layer is 3~5mm.
Preferably, a kind of exothermic welding mould above-mentioned, first diversion trench is isometrical straight hole slot, the second diversion trench
The flaring slot incrementally increased downwards for diameter.
The utility model has clear advantage and advantageous effect compared with prior art.By above-mentioned technical proposal, originally
A kind of exothermic welding mould of utility model at least has following advantages and advantageous effect：
The utility model uses the mode for being provided separately reaction mould and welding mould, and welding mould is divided into upper and lower two portions
Divide and steel material is used to carry out outer protection, at the hole of welded part.During normal exothermic weld,
It is still to combine to react the upper surface of mould and welding mould part, and a combination thereof component is rapid latch, is placed to welded part
Hole uses steel material protection, and steel plate layer can slow down welded part and damage the abrasion of die graphite material and stress；
And since steel plate protective layer is located at the outside of graphite material, the not direct high-temperature soldering liquid with melting contacts, in normal operation
Do not have the danger being melted.
