Air-cooled rapid cast-weld mold

Technical Field

The invention belongs to the technical field of cast-weld molds, and particularly relates to an air-cooled rapid cast-weld mold.

The bus bars and the poles are generally formed by cast welding using a cast-weld mold.

The existing cast-weld mold is generally a water-cooling cast-weld mold, and the water-cooling mold is easy to cause scaling of an inner cavity of the mold due to impurity ions contained in cooling water, so that a water channel of the mold is blocked, the heat dissipation and heat absorption effects of the mold are influenced, and due to the reason, the existing cast-weld defect rate is large in fluctuation, and the service life of the cast-weld mold is short.

Aiming at the problems, the mold body is made of OOCr12 heat-resistant steel, the air inlet air passage and the air outlet air passage are arranged, and compressed air is introduced, so that the mold has the effects of slowing down the loss generated by the mold cavity structure, being difficult to oxidize and deform under the working environment of 600-700 ℃ and avoiding the scaling of the inner cavity of the mold.

Disclosure of Invention

The invention aims to provide an air-cooling rapid cast-welding mould, which solves the problems that the existing water-cooling mould is easy to cause scaling of the inner cavity of the mould due to impurity ions contained in cooling water, so that the water channel of the mould is blocked, the heat radiation and heat absorption effects of the mould are influenced, the defect rate fluctuation of the existing cast-welding is large, and the service life of the cast-welding mould is short by adopting OOCr12 heat-resistant steel material for a mould body, arranging an air inlet air channel and an air outlet air channel and introducing compressed air.

In order to solve the technical problems, the invention is realized by the following technical scheme:

the invention relates to an air-cooled rapid cast-weld mould, which comprises a mould body; the die body is provided with a die cavity; one end of the die body is provided with a plurality of air inlet air passages; the other end of the die body is provided with a plurality of air outlet channels; the die body is made of OOCr12 heat-resistant steel.

Furthermore, the thickness of the die cavity is 1mm, and the overall weight is lighter than that of the existing die.

Furthermore, the inside compressed air who is used for cooling the mould body that leads to of air inlet duct has avoided the water-cooling cast joint mould because the impurity ion that contains in the cooling water, easily leads to the mould inner chamber scale deposit.

Furthermore, compressed gas for cooling the die body is communicated into the gas outlet air channel.

Furthermore, a plurality of air inlet air passages and a plurality of air outlet air passages are respectively provided with 7mm ventilation pipelines.

The invention has the following beneficial effects:

1. the mold body is made of OOCr12 heat-resistant steel, so that the mold is difficult to oxidize and difficult to deform in the working environment of 600-700 ℃.

2. According to the invention, compressed air is introduced into the air inlet passage, so that the phenomenon that the water channel of the water-cooled cast-weld mould is blocked to influence the heat dissipation of the mould due to the fact that the inner cavity of the mould is easily scaled by impurity ions contained in cooling water is avoided, and the loss generated by the structure of the mould cavity is also reduced.

3. According to the invention, the thickness of the die cavity is 1mm, and the air inlet air passage and the air outlet air passage both adopt 7mm ventilation pipelines, so that the whole weight of the die body is reduced, the load on equipment in the working process is weaker than that of the existing die, and the stability of the equipment in the cast-weld process is improved.

Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
