Weld mold
Technical field
The present invention relates to Mold Making technical field, specifically refer to a kind of weld mold.
Background technology
Welding is the important means realizing firmly connecting between metal, and traditional welding must can work by external power supply driving arrangement, and there is the defect that efficiency is low, labour intensity is large.Therefore now there is various weld mold for different welding materials, existing weld mold generally all comprises mold and die cover, mold and die cover involutory after in mold forming reactions chamber, drainage trough and welding chamber, steel dish is placed in reaction chamber and reaction chamber and drainage trough is separated, welding powder is positioned in reaction chamber, after ignition powder lighted by use burning torch, thermit reaction is there is in welding powder in reaction chamber, the high temperature solution penetration steel dish that this reaction produces, welding chamber is flowed to by drainage trough, and in welding chamber by the abutting end founding of two conductors to be connected together, thus complete intermetallic chemistry welding.This weld mold is without the need to the external energy, and have easy to carry, operating efficiency high, whole welding process only needs several seconds time.The die cover plate of these weld molds in addition all offers smoke intaking hole, venthole, the flue gas produced in reaction chamber can be discharged by flue.
As the Chinese utility model " a kind of weld mold " that the patent No. is CN201120131707.8, comprise one and be fixedly connected with the die ontology of arranging in pairs or groups in order to weld the first conductor and the second conductor with fixture, one positioner and be connected with the second conductor contact and with die ontology is arranged at the retention device in the second conductor, adjustment positioner, second conductor is pressed in die ontology, to make in welding process the first conductor and the second conductor all the time position relative fixing near and can not be separated, thus failure welding can not be caused even not weld at all, and also can find out in drawing, the lower end of its die cover plate has smoke intaking hole, venthole is then the upper end being located at die cover plate, such flue gas is just directly discharged, similar with the cover plate of above-mentioned weld mold, the effect of purification can not be played to the flue gas of discharging, and the flue gas of directly discharging also can to environment, therefore its structure needs to improve.
