Abstract
A kind of case of reducer casting technique adding chill, described casting step is: (a) first casting machine carries out moulding by tide mould sand, forms upper impression and lower impressions；B () puts into chill in lower impressions；C () upper impression and lower impressions carry out matched moulds；In the die cavity of matched moulds, pouring molten iron is carried out after (b)；After (e) formed product drawing, enter reciprocating sieve, by reciprocating sieve, the tide mould sand of product periphery is cleaned out, finally obtain product；It is an object of the invention to overcome the deficiencies in the prior art, a kind of case of reducer casting technique adding chill of proposition, it is allowed to the cabinet qualified product produced, improves production efficiency, reduce cost.
Description
Technical field
The present invention relates to casting technology field, be specifically related to a kind of case of reducer casting technique adding chill.
Background technology
When generally producing case of reducer, need, through processes such as moulding, matched moulds, cast, post processings, to eventually form product
Cabinet, in moulding during this, original is to carry out moulding by manual, inefficiency, wastes time and energy, cost of increasing input,
Now use machine to replace by hand and carry out moulding, although improve work efficiency, reduce cost but there is also some defects, such as: making
During after type, matched moulds carries out pouring into a mould this, due to case of reducer in cooling procedure inhomogeneous cooling with, cause reductor machine
Case surrounding thin-walled is uneven, makes product occur interior tissue shrinkage porosite at wall thickness, can be seen that obvious poroid tissue, seriously after molding
Affect product quality, cause product quality defective, increase cost.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, a kind of case of reducer founder adding chill of proposition
Skill, is allowed to the cabinet qualified product produced, and improves production efficiency, reduces cost.
The technical solution of the present invention: a kind of case of reducer casting technique adding chill, it is characterised in that described
Casting step is:
A () first casting machine carries out moulding by quartz sand, form upper impression and lower impressions；B () puts in lower impressions
Chill；C () upper impression and lower impressions carry out matched moulds；In the die cavity of matched moulds, pouring molten iron is carried out after (d)；(e) formed product
After drawing, enter reciprocating sieve, by reciprocating sieve, the tide mould sand of product periphery is cleaned out, finally obtain product.
As the further optimization of this programme, described molten iron temperature is between 1350 DEG C-1400 DEG C.
As the further optimization of this programme, described cool time is between 40 minutes to 50 minutes.
As the further optimization of this programme, described chill is loop configuration, by spray gun spraying one around described chill
Layer pick argentum powder alcohol-base paint.
As the further optimization of this programme, described pick argentum powder alcohol-base paint has high temperature resistant, corrosion resistance characteristic.
As the further optimization of this programme, the described pick resistant to elevated temperatures temperature of argentum powder alcohol-base paint is at 1650 DEG C-1750 DEG C
Between.
As the further optimization of this programme, described tide mould sand is made up of fine quartz sand, coal dust and clay.
Beneficial effects of the present invention:
The present invention, by original case of reducer foundry technology process, adds this one work of chill after moulding
Sequence, when being allowed to cool down, uniformly, rate of cooling is consistent in cabinet cooling, is not result in that case of reducer surrounding thin-walled is uneven, makes product
Interior tissue shrinkage porosite occurs at wall thickness, after molding, can be seen that the situation of obvious poroid tissue, improve conforming product rate, reduce
Cost, improves production efficiency.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with accompanying drawing:
Fig. 1 is that in the present invention, die cavity and chill cooperate structural representation:
Fig. 2 is chill structural representation of the present invention；
In figure: 1, upper impression, 2, lower impressions, 3, chill.
Detailed description of the invention
With reference to the accompanying drawings the present invention is described more fully, the exemplary embodiment of the present invention is wherein described.Under
Face will combine the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, aobvious
So, described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the reality in the present invention
Execute example, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all belong to
In the scope of protection of the invention.Below in conjunction with figure and embodiment, technical scheme is carried out many descriptions.
Embodiment:
As depicted in figs. 1 and 2, a kind of case of reducer casting technique adding chill, it is characterised in that described casting walks
Suddenly it is:
A () first casting machine carries out moulding by quartz sand, form upper impression 1 and lower impressions 2；B () puts in lower impressions
Enter chill 3；C () upper impression and lower impressions carry out matched moulds；In the die cavity of matched moulds, pouring molten iron is carried out after (d)；E () product becomes
After type drawing, enter reciprocating sieve, by reciprocating sieve, the tide mould sand of product periphery is cleaned out, finally obtain product.
As the further optimization of this programme, described molten iron temperature is between 1350 DEG C-1400 DEG C.
As the further optimization of this programme, described cool time is between 40 minutes to 50 minutes.
As the further optimization of this programme, described chill is loop configuration, by spray gun spraying one around described chill
Layer pick argentum powder alcohol-base paint.
As the further optimization of this programme, described pick argentum powder alcohol-base paint has high temperature resistant, corrosion resistance characteristic.
As the further optimization of this programme, the described pick resistant to elevated temperatures temperature of argentum powder alcohol-base paint is at 1650 DEG C-1750 DEG C
Between.
As the further optimization of this programme, described tide mould sand is made up of fine quartz sand, coal dust and clay.
Specific works process:
As depicted in figs. 1 and 2, the present invention first casting machine carries out moulding by quartz sand, forms upper impression and lower impressions,
Putting into chill in lower impressions, upper impression and lower impressions carry out matched moulds afterwards；Pouring molten iron is carried out again in the die cavity of matched moulds；Produce
After product molding drawing, enter reciprocating sieve, by reciprocating sieve, the tide mould sand of product periphery is cleaned out, finally obtain product, logical
