Abstract
The invention discloses a casting process for cylinder sleeves. The process includes the steps: making a mould for the cylinder sleeves; making a mould joint with a side gate according to casting specifications to obtain a molding box of an external mould, a positioning core and a gate core; arranging a gate and a feed head on the mould; adding clay sand into the mould for clay sand molding, and matching 1.25-1.45% of furan resin and sulfonic acid accounting for 30-60% of the resin to serve as curing agents; patching the molded clay sand mould and brushing coating on the surface of the same; subjecting the clay sand mould to mould matching and mould assembling; pressing the clay sand mould; placing a pouring cup on the pouring gate of the mould and placing a feed head cup on the feed head; and pouring melted iron into a cavity of the clay sand mould by a crane ladle for casting. The casting process for the cylinder sleeves has the advantages of short period, high work efficiency, low cost and wide application range in mould manufacturing.
Description
Technical field:
The present invention relates to a kind of casting technique of cylinder sleeve.
Background technology:
At present, the conventional method of producing the cylinder sleeve foundry goods now is centrifugal casting, but need select boron cast iron or various alloy cast iron for use because of material; But boron cast iron is easy to generate deviation; And in the end solidify place's generation deviation, and its cooling direction is from outside to inside, therefore the last cooling of endoporus is easy to generate deviation.Again because of action of centrifugal force, make nonmetal oxide simultaneously, slag inclusion all is adsorbed on the endoporus of cylinder sleeve, after the interior aperture processing, casting flaw in various degree just occurred, like phenomenons such as slag inclusion, oxide, hickies.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency the casting technique of the cylinder sleeve that provide a kind of and can not produce deviation, improved wearability, production cost is low.
The object of the invention is realized through following technical scheme: a kind of casting technique of cylinder sleeve may further comprise the steps:
The mould of A, making cylinder sleeve;
B, make band runner gate die joint by the casting standard and get external model sandbox, loam core, location, cast gate loam core;
C, cast gate and rising head are set on mould;
D, clay-bonded sand is put into mould, carry out the clay-bonded sand moulding, and the sulfonic acid class that is equipped with the furane resins of 1.25-1.45% and accounts for resin 30-60% is made curing agent;
E, the clay-bonded sand mould after the moulding is repaiied type, and at its surface brush coating;
F, the clay-bonded sand mould is joined mould, mould assembling;
G, the clay-bonded sand mould is pressed case;
H, on the cast gate of mould, put cup, on rising head, put and emit cup;
I, with bull ladle molten iron is poured in the die cavity of clay-bonded sand mould and cast.
The present invention compared with prior art has the following advantages: with its inwall compact crystallization of cylinder sleeve, the even hardness of the method cast, can not produce deviation, do not have any casting flaw; Improved wearability; Be applicable to a large amount of productions continuously; And can make full use of foundry return, production safety, yield rate be high, reduced production cost.
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 cylinder sleeve of the present invention may further comprise the steps:
The mould of A, making cylinder sleeve;
B, make band runner gate die joint by the casting standard and get external model sandbox, loam core, location, cast gate loam core;
C, cast gate and rising head are set on mould;
D, clay-bonded sand is put into mould, carry out the clay-bonded sand moulding, and the sulfonic acid class that is equipped with the furane resins of 1.25-1.45% and accounts for resin 30-60% is made curing agent;
E, the clay-bonded sand mould after the moulding is repaiied type, and at its surface brush coating;
F, the clay-bonded sand mould is joined mould, mould assembling;
G, the clay-bonded sand mould is pressed case;
H, on the cast gate of mould, put cup, on rising head, put and emit cup;
I, with bull ladle molten iron is poured in the die cavity of clay-bonded sand mould and cast.
With its inwall compact crystallization of cylinder sleeve, the even hardness of the method cast, can not produce deviation, do not have any casting flaw; Improved wearability; Be applicable to and a large amount of produce continuously, and can make full use of foundry return that production safety, yield rate be high, reduced production cost.
