Abstract
The invention discloses a technological method for casting a tooth-shaped part, and particularly relates to a technological method for carrying out direct casting modeling on the tooth-shaped part. According to the method, an iron mould-tectorial sand technology is adopted to obtain a complete tooth-shaped cavity, a tooth shape is directly cast, and the cutting-free or minute-quantity-cutting technological method is achieved. The method is low in cost, simple, easy to implement and suitable for being used by most enterprises.
Description
Technical field
The invention belongs to casting technology field, be specifically related to a kind of tooth form part foundry technique method.
Background technology
Profiled parts at least has one for connecting the profile of tooth cavity of miscellaneous part, in current tooth form part foundry technique, the profiled parts made does not have profile of tooth cavity or cavity very little, need processing further, not only casting process is more, affect production capacity, the precision of foundry goods cannot effectively be ensured simultaneously, and percent defective is higher.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field exists, the object of the invention is to, provide a kind of tooth form part foundry technique method, directly can cast out profiled parts, the precision of foundry goods is high, and processing technology thereof is simple.
Tooth form part foundry technique method provided by the invention, comprises the following steps:
(1) design a set of with the completely the same model of the profile of tooth of profiled parts as master mold;
(2) make the swage external form that is associated with master mold, swage profile and master mold supporting time its gap be 6 ~ 9mm;
(3) master mold is fixed on penetrates on sand machine, and swage external form of closing, be heated to 260 ~ 300 DEG C of insulations, 30 minutes sand to be penetrated together;
(4) precoated sand is incident upon on pre-designed swage by penetrating sand machine sand-spraying hole, precoated sand is made to be filled to cavity between model and swage, molding after 1 minute half, after naturally cooling, obtain the upper and lower swage die cavity covering sand successively, namely through covering sand can mould assembly cast die cavity;
(5) complete to overlay film swage carries out the surface coating that surface of internal cavity sprays one deck 0.15mm;
(6) the qualified molten iron of the fixing rear cast of mould assembly just obtains required profile of tooth blank part.
Tooth form part foundry technique method provided by the invention, its beneficial effect is, overcomes operation in prior art process more, the problem that workload is large, improves production efficiency; Avoid because of the defective mass defect caused of raw material allotment, utilization rate of raw materials is high, reduces production cost; The profiled parts size of the finished product cast out is accurate, without the need to machining, effectively ensure that casting quality.
Detailed description of the invention
Below in conjunction with an embodiment, tooth form part foundry technique method provided by the invention is described in detail.
Embodiment
The tooth form part foundry technique method of the present embodiment, comprises the following steps:
(1) design a set of with the completely the same model of the profile of tooth of profiled parts as master mold;
(2) make the swage external form that is associated with master mold, swage profile and master mold supporting time its gap be 8mm;
(3) master mold is fixed on penetrates on sand machine, and swage external form of closing, be heated to 285 DEG C of insulations, 30 minutes sand to be penetrated together;
(4) precoated sand is incident upon on pre-designed swage by penetrating sand machine sand-spraying hole, precoated sand is made to be filled to cavity between model and swage, molding after 1 minute half, after naturally cooling, obtain the upper and lower swage die cavity covering sand successively, namely through covering sand can mould assembly cast die cavity;
(5) complete to overlay film swage carries out the surface coating that surface of internal cavity sprays one deck 0.15mm;
(6) the qualified molten iron of the fixing rear cast of mould assembly just obtains required profile of tooth blank part.
Tooth form part foundry technique method, can directly cast out profile of tooth cavity, and without the need to machining, operation is simple, and the finished product profiled parts size cast out is accurate, is suitable for most enterprises and uses.
Claims (1)
1. a tooth form part foundry technique method, is characterized in that: said method comprising the steps of:
(1) design a set of with the completely the same model of the profile of tooth of profiled parts as master mold;
(2) make the swage external form that is associated with master mold, swage profile and master mold supporting time its gap be 6 ~ 9mm;
(3) master mold is fixed on penetrates on sand machine, and swage external form of closing, be heated to 260 ~ 300 DEG C of insulations, 30 minutes sand to be penetrated together;
(4) precoated sand is incident upon on pre-designed swage by penetrating sand machine sand-spraying hole, precoated sand is made to be filled to cavity between model and swage, molding after 1 minute half, after naturally cooling, obtain the upper and lower swage die cavity covering sand successively, namely through covering sand can mould assembly cast die cavity;
(5) complete to overlay film swage carries out the surface coating that surface of internal cavity sprays one deck 0.15mm;
(6) the qualified molten iron of the fixing rear cast of mould assembly just obtains required profile of tooth blank part.
