The supporting pad is rubber pad, the intermediate aperture of rubber pad, opening among supporting pad as a preferred technical solution,
A vertical grounding electrode is inserted into hole, vertical grounding electrode sealing is inserted in the hole among rubber pad.
The gasket is made of stainless steel or pure copper material as a preferred technical solution,.
The positioning sleeve is copper sheathing as a preferred technical solution, and a location hole, the outer wall of copper sheathing is arranged among copper sheathing
Compression is contacted with aperture inner wall.
The charging aperture of a perforative ceramic upper cover is opened up among ceramic upper cover as a preferred technical solution, it is external
Ignite powder or pyrophoric powder passes through this charging aperture and is added in die cavity and generates high-temperature copper liquid with the welding powder haptoreaction in die cavity.
The beneficial effects of the invention are as follows：The present invention solves on a small scale, and the exothermic weld of small number is at high cost, and construction is complicated
The problems such as, using ceramic material, ceramics have feature resistant to high temperature, are able to satisfy the requirement of exothermic weld, can be large quantities of by mold
Amount production.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is external structure schematic diagram of the invention；
Fig. 2 is inner section schematic diagram of the invention；
Fig. 3 is the structural schematic diagram of gasket of the invention；
Fig. 4 is the structural schematic diagram of gasket pallet of the invention.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As depicted in figs. 1 and 2, including using die main body 3 made of ceramic material, the top of die main body 3 has one
A mold upper cover 6 opens up a die cavity 12 inside die main body 3, and die cavity is packed into a gasket pallet 2, as shown in figure 4, gasket support
2 upper ends of disk, one gasket 1, the bottom surface of die cavity are a taper support face 7, and the engagement of 2 bottom of gasket pallet is installed on taper branch
On support face 7, the two sides of the bottom that die cavity is located at gasket pallet respectively open up the aperture communicated with the outside world 4, are packed into one in aperture
Positioning sleeve 11, product to be welded pass through positioning sleeve and are inserted into inside die main body.
In the present embodiment, die main body 3, mold upper cover 6 are all made of ceramic material and are made.It can directly be abandoned after the completion of operation
It is free from environmental pollution；The waste of graphite resource can be reduced.
Wherein, the bottom of die main body 3 is additionally provided with a cavity, and cavity chamber is packed into a supporting pad 5, and supporting pad 5 is rubber
Pad, the intermediate aperture of rubber pad.In the present invention, supporting pad uses disposable structure, changes the knot that traditional long-time uses
Structure, the replacement that this disposable structure can be convenient reduce cost in the case where welding access times less
Waste.
In the present embodiment, as shown in figure 3, gasket is made of stainless steel.When welding, the copper liquid of pyroreaction occurs
Can be contacted with gasket, and gasket be melted, gasket for placing welding powder, when react become molten copper liquor it
Afterwards, the high-temperature copper liquid of melting, which melts away, gasket and enters die cavity lower part, and realization welding is contacted with the product to be welded protruded into, that is, is solved
It has determined placement problem, and has not influenced to weld.
In the present embodiment, positioning sleeve is copper sheathing, a location hole is arranged among copper sheathing, outer wall and the aperture inner wall of copper sheathing connect
