Abstract
The invention discloses a casting process of a gearbox. The casting process includes following steps: manufacturing a mould of the gearbox; fixing the mould on a sand shooter, heating the mould to a temperature of 300-350 DEG C, and keeping the mould warm for 20-40 minutes for sand shooting; shooting resin sand into the mould through a sand shooting hole of the sand shooter so that a cavity of the mould is filled with the resin sand; patching the molded resin sand mould and painting the surface of the mould; arranging and assembling the resin sand mould; lifting the boxes of the resin sand mould; placing a sprue cup on a sprue gate of the mould, and placing a riser cup on a riser of the mould; and casting melted iron into the cavity of the resin sand mould by the aid of a crane ladle for casting. The casting process of the gearbox has the advantages of capability of quantity production, high production efficiency and fine product quality.
Description
Technical field:
The present invention relates to a kind of casting technique of gear-box.
Background technology:
In present commercial production, various gear-boxes are used widely, but because the inherent characteristic of gear-box makes it in use very easily receive wearing and tearing, so just cause parts to need to change timely.At present, the casting of gear-box all obtains through mechanical process technique, that is to say that employing carries out the method for cut to part blank, it is processed as needed shape, thereby makes the production efficiency of gear-box lower, product second-rate.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, provide a kind of and produce in batches, production efficiency is high, the casting technique of the gear-box of good product quality.
The object of the invention is realized through following technical scheme: a kind of casting technique of gear-box may further comprise the steps:
The mould of A, making gear-box;
B, be fixed on mould and penetrate on the sand machine, be heated to 300-350 ℃, be incubated 20-40 minute sand to be penetrated;
C, be incident upon resin sand in the mould through penetrating sand machine sand-spraying hole, make resin sand be full of the cavity of mould;
D, the resin sand mould after the moulding is repaiied type, and at its surface brush coating;
E, the resin sand mould is joined mould, mould assembling;
F, the resin sand mould is carried out box;
G, on the cast gate of mould, put cup, on rising head, put and emit cup;
H, with bull ladle molten iron is poured in the die cavity of resin sand mould and cast.
The present invention compared with prior art has the following advantages: the present invention passes through mfg. moulding die; And through penetrating the cavity that the sand machine is full of resin sand on mould; Obtain complete resin sand mould; Adopt casting technique directly to cast out gear-box afterwards, can make high-precision gear-box in batches after adopting this method, reach the production technology of not having cutting or minute quantity cutting.
The specific embodiment:
In order to deepen to understanding of the present invention, will combine embodiment that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
A kind of specific embodiment of the casting technique of gear-box of the present invention may further comprise the steps:
The mould of A, making gear-box;
B, be fixed on mould and penetrate on the sand machine, be heated to 300-350 ℃, be incubated 20-40 minute sand to be penetrated;
C, be incident upon resin sand in the mould through penetrating sand machine sand-spraying hole, make resin sand be full of the cavity of mould;
D, the resin sand mould after the moulding is repaiied type, and at its surface brush coating;
E, the resin sand mould is joined mould, mould assembling;
F, the resin sand mould is carried out box;
G, on the cast gate of mould, put cup, on rising head, put and emit cup;
H, with bull ladle molten iron is poured in the die cavity of resin sand mould and cast.
The present invention passes through mfg. moulding die; And through penetrating the cavity that the sand machine is full of resin sand on mould; Obtain complete resin sand mould; Adopt casting technique directly to cast out gear-box afterwards, can make high-precision gear-box in batches after adopting this method, reach the production technology of not having cutting or minute quantity cutting.
