Abstract
The invention relates to a process for manufacturing a cooling water pipe of an automobile interior trim part steel casting mould. The process is characterized by comprising the following technological steps of: firstly bending a seamless steel tube into a shape consist with the moulded surface of the mould to form a cooling water pipe; bonding a foam plate in certain thickness outside the cooling water pipe; placing the cooling water pipe provided with the foam plate into a sand mould cast by the automobile interior trim part steel casting mould; and finally casting, wherein a cast steel casting material forms a mould main body while the mould main body substitutes the foam plate to cover and fix the cooling water pipe. The processing technique has the advantages that the cooling water pipe prepared by the seamless steel pipe and the mould main body are molten into a whole in the invention, thus the heat conduction loss is almost zero and good cooling of the mould is realized. Meanwhile, casting and moulding are carried out in one step, procedures are less, the manufacturing cost is low, the quality of a casting is stable, and no casting deformation caused by secondary casting exists.
Description
Technical field
The present invention relates to a kind of preparation method of automotive upholstery cast steel mould cooling water pipe, be specifically related to a kind ofly be cast to method in the automotive upholstery cast steel mould by pre-buried seamless steel pipe.
Background technology
The preparation method of automotive upholstery cast steel mould cooling water pipe in the market is by first casting mould cast steel body, the technology of second casting corrugated stainless steel tubing then.
Promptly at first cast as the steel-casting of die main body; Secondly, corrugated stainless steel tubing is bent to the cooling water pipe of applying die main body profile; By second casting layer of aluminum alloy corrugated stainless steel tubing is covered and is fixed on die main body at last.It exists shortcoming to be: this process not only technology step many, the cost of the aluminium alloy of corrugated stainless steel tubing and casting is all than higher, and because the aluminium alloy of second casting exists to be shunk, and between the die ontology of cast steel shrinkage joint arranged, and reduced cooling effect.Easily cause casting deformation in addition during the second casting aluminium alloy.
Summary of the invention
The technical problem to be solved in the present invention has provided that a kind of operation is few, cost of manufacture is low, the automotive upholstery cast steel mould cooling water pipe manufacture craft of good cooling results.
In order to solve above technical problem, technical scheme of the present invention is: a kind of automotive trim cast steel mould cooling water pipe manufacture craft, and its innovative point is that this processing step is: at first seamless steel pipe is bent to the shape that conforms to die face and make cooling water pipe; Bonding certain thickness cystosepiment outside cooling water pipe; The cooling water pipe of band cystosepiment is placed the sand mold of automotive upholstery cast steel die casting; Cast at last, the cast steel material of casting replaces that cystosepiment covers and fixing cooling water pipe when forming die main body.
Further, the wall thickness of described seamless steel pipe is about 8-10mm.
Further, the described cast steel material thickness of seamless steel pipe outside that is coated on is between 3-5mm.
The advantage of above processing technology is: cooling water pipe and the die main body made by seamless steel pipe among the present invention fuse into one, so heat conduction losses is almost nil, thus the good cooling of realization mould.And a cast molding, operation is few, and cost of manufacture is low, and the quality of foundry goods is also stable, the casting deformation that does not have second casting and caused.
The wall thickness of seamless steel pipe is between 8-10mm, and the cast steel material thickness that coats this seamless steel pipe when guaranteeing that cooling water pipe is fixing, avoids cast steel material to cause the thawing distortion of cooling water pipe when casting between 3-5mm.
The specific embodiment
The present embodiment processing step is:
The first step, carry out the processing of cooling water pipe: the bubbles model that at first processes automotive upholstery cast steel die main body with foamed material, according to the die main body profile situation cooling water pipe distributing position that on bubbles model, draws, and process the cooling water pipe locating slot according to the position, with this cooling water pipe locating slot is benchmark, with thickness is that the seamless steel pipe of 8-10mm carries out bending, and it can be embedded in the locating slot, realizes fitting substantially with bubbles model;
Second step, bonding cystosepiment outside the good cooling water pipe of bending, the thickness of cystosepiment is between 3-5mm;
The 3rd step moulding places the sand mold that carries out automotive upholstery cast steel die casting with the cooling water pipe of bonding cystosepiment, and make its apart from the distance of die face between 30-35mm
The casting of the 4th step, cast steel material injects and forms die main body in the sand mold, and replace that cystosepiment covers and fixing cooling water pipe, the cast steel material thickness that coats cooling water pipe is the thickness 3-5mm of cystosepiment, when the molten steel of this thickness coats cooling water pipe, can guarantee the fixing of cooling water pipe, can avoid it when casting, to cause the thawing distortion of cooling water pipe again.
