Abstract
The invention relates to a pre-buried type fusion tube and a processing die and a processing method thereof, wherein the pre-buried type fusion tube is formed by adopting integral casting, thus the problem of sealing performance can be effectively solved; a first skewed slot and a second skewed slot are formed in a metal piece and a top cover respectively, thus the sealing effect and the firmness of the whole structure can be both improved; by adding a limiting slot in the processing die, the metal piece and/or the top cover can be accurately positioned, and slippage can also be prevented; and with arrangement of a slanting angle, being 0.5 degree, on a neutron loose core, demolding is convenient. In the processing method, the metal piece and the top cover are heated to 70-90 DEG C firstly, so that a gap generated by thermal expansion and cold contraction can be effectively prevented; and finally, as for the sequence of demolding, a male mold is removed firstly, and a female mold is reserved, so that when the neutron loose core is extracted, the casted fusion tube can be stressed at a female mold part, thus extraction of the neutron loose core is facilitated, damages are reduced, the qualified ratio of a product is increased, the production cost is also greatly lowered, and the core competitiveness of an enterprise is improved.

The processing method of a kind of built-in type fusion tube using described processing mold to make, comprises the following steps:
1) metalwork 2 and top cover 3 are heated to 70-90 DEG C；
2) metalwork 2 and top cover 3 are positioned between male model 4 and master mold 5；
3) by male model 4 and master mold 5 matched moulds, make metalwork 2 and top cover 3 coaxial, and the first limiting section 22 and/or second is spacing
Portion 32 is positioned at stopper slot 7；
4) axis along metalwork 2 with top cover 3 inserts neutron and looses core 6；
5) casting；
6) demoulding, first takes off male model 4, then extracts neutron out and loose core 6, finally takes off master mold 5.
Arrow in Figure 12 show male model 4 and the direction of master mold 5 matched moulds, and neutron is loosed core the side of 6 insert type intracavity
To.
Step 2) in, metalwork 2 and top cover 3 are heated to 70-90 DEG C, such as 80 DEG C.
Compared with prior art, this built-in type fusion tube uses one cast molding, it is possible to effectively solve sealing problem,
First skewed slot 24 and the second skewed slot 35 is set on metalwork 2 and top cover 3, can not only lift-off seal effect, and can promote
The firmness of total；Stopper slot 7 is added, it is possible to realize metalwork 2 and/or top cover 3 is accurate on this processing mold
Location, and prevent from skidding, neutron is loosed core and 6 is arranged the inclination angle of 0.5 °, it is simple to the demoulding；In this processing method, first by metalwork 2
It is heated to 70-90 DEG C, it is possible to be effectively prevented from the gap produced because expanding with heat and contract with cold with top cover 3；The order of the last demoulding, first takes off
Male model 4, retains master mold 5 so that neutron loose core 6 extraction time, fusion tube cast can in master mold 5 position stress, beneficially in
Son is loosed core 6 extractions, reduces damage, improves the qualification rate of product.
