Abstract
The invention discloses a shape following device which is an iron shell with the thickness of 10 to 12 mm. The inner wall of the iron shell is coated with a sand coating layer with the thickness of 3 to 4 mm. The invention further discloses an iron die sand coating process adopting the device. The shape following device and the iron die sand coating process can bring the following effects that 1, the production efficiency is improved; 2, the cost of raw materials is reduced; 3, the problem of air holes is solved; 4, the inner quality of the iron die sand coating process adopting a horizontal line is higher than that of an iron die sand coating process.
Description
Technical field
The present invention relates to auto parts and components processing technique field, especially a kind of for the manufacture of turbocharger housing with type device, and adopt this with the device for sand coated iron mould technique of type device.
Background technology
Turbocharger housing is a strength member on automobile, it belongs to thin-wall part, complex structure, material is austenitic magnesium iron, shrink tendency large, the casting technique of existing manufacture turbocharger housing is device for sand coated iron mould technique, and this technique is with type inner surface, to be covered with the overlay film layer of sand of 5-8mm at upper drag box, then play core, mould assembly, cast, utilize the chilling action of swage sandbox and stable rigidity to make foundry goods dense structure, size accurate.But the shortcoming of this technique is: (1) sandbox is heavy, and production efficiency is low, average production 12 casees per hour, sand removal difficulty; (2) precoated sand cost is high, and sandbox inner surface covers 8-10mm and covers layer of sand, and the consumption of precoated sand is large, and cost increases; (3) use swage sandbox, the gas that in casting process, precoated sand produces is difficult for discharging, and gas hole defect easily appears in product.
The casting technique that horizontal parting high-pressure molding line adopts is common tide mould sand casting technique, and its advantage is: production efficiency is high, and exhaust performance is good, and sand removal is easy.Shortcoming is: the chill effect of molding sand and poor rigidity, can not guarantee the quality of austenitic magnesium iron product.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind ofly with type device, make the manufacture efficiency of device for sand coated iron mould technique high, cost is low and exhaust is easy.
In order to realize foregoing invention object, the invention provides following technical scheme: a kind of with type device, be the thick iron-clad of 10-12mm, on this iron-clad inwall, be covered with 3-4mm and cover layer of sand.
Further, this iron-clad is that upper and lower two parts constitute by an active connection.
A technique, comprises lower core, mould assembly, cast, and this lower core is for carrying out in type device above-mentioned.
Compared with prior art, the present invention has the following advantages: this is applicable to horizontal and vertical somatotype mo(u)lding line with type device, can bring following effect:
1. improved production efficiency, adopted 12 casees products of device for sand coated iron mould technique production per hour of apparatus of the present invention, adopted 100 casees products of horizontal device for sand coated iron mould technique production per hour, production efficiency improves 8.3 times.
2. reduced the cost of raw material, on average covering layer of sand is 5-8mm, adopting the sand layer thickness that on average covers of horizontal line device for sand coated iron mould technique is 3-4mm, and the precoated sand consumption of the old technique of precoated sand amount ratio of adopting new technology has reduced 30%, and the use cost of precoated sand just reduces by 30%.
3. solve pore problem, the sandbox of the device for sand coated iron mould process using gas that precoated sand produces in casting process is difficult for discharging, and adopts the good advantage of device for sand coated iron mould technology utilization tide mould sand casting technique venting quality of horizontal parting high-pressure molding line to solve the problem that product air holes is many;
4. adopt the inherent quality of horizontal device for sand coated iron mould technique higher than the inherent quality of device for sand coated iron mould technique.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, describe the present invention, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
As shown in Figure 1 a kind of with type device, for average thickness 10-12mm thick with sections shell 1, replace traditional overlay film sandbox, cover layer of sand 2 being covered with 3-4mm with sections shell 1 inwall.
Corresponding when adopting device for sand coated iron mould technique to manufacture turbocharger housing, with sections shell 1 cover the interior lower core of layer of sand 2, then will under after sections shell mould assembly, in horizontal die cavity, produce up and down.
Claims (3)
1. with a type device, it is characterized in that: be the thick iron-clad of 10-12mm, on this iron-clad inwall, be covered with 3-4mm and cover layer of sand.
2. as claimed in claim 1 with type device, it is characterized in that: this iron-clad is that upper and lower two parts constitute by an active connection.
3. a device for sand coated iron mould technique, comprises lower core, mould assembly, cast, and this lower core for to carry out in as claimed in claim 1 with type device.
