Abstract
The utility model discloses a mould for casing casting parts, including pouring basin, sprue, filter screen, cross gate, foundry goods, psammitolite, rising head, the sprue links to each other with the pouring basin, the filter screen is located the faying surface of sprue and cross gate, the cross gate passes through the rising head and links to each other with the foundry goods, the surface at the psammitolite is installed to the foundry goods. The utility model discloses a mould for casing casting parts adds the rising head in the middle of the foundry goods, the bad phenomenon of seepage, shrinkage porosite or shrinkage cavity and foundry goods surface outward appearance has been avoided appearing through rising head inflow foundry goods die cavity by metal liquid between foundry goods and the psammitolite, install the filter screen on sprue and the cross gate faying surface, bubble in the effective removing metal liquid of filter screen, press from both sides harmful impurity such as grey oxide and various inclusions, eliminated gas hole, slag blister, the blowholes of foundry goods, improve the yield of foundry goods greatly, improve the inner quality and the appearance quality of foundry goods.
Description
Technical field
The utility model relates to Foundry Production technical field, particularly relates to a kind of mould for shell cast parts.
Background technology
Casting Metal Melting is smelt meet necessarily required liquid and water enter in casting mold, through cooled and solidified, level process after obtain the technical process of the foundry goods of predetermined shape, size and performance.Shell cast parts are being built in forming process, between foundry goods and core, easily occur seepage, shrinkage porosite or shrinkage cavity phenomenon, make the disqualification rate of converted products higher, but also can there is the phenomenon of cast(ing) surface bad order.
Utility model content
The purpose of this utility model is in order to solve the defect problem of the higher and cast(ing) surface bad order of above-mentioned shell cast parts disqualification rate, a kind of mould for shell cast parts is provided, this mould adds rising head in the middle of foundry goods, molten metal flows into foundry goods die cavity through rising head, avoid the phenomenon occurring seepage, shrinkage porosite or shrinkage cavity and cast(ing) surface bad order between foundry goods and core, effectively improve the qualification rate of foundry goods.
The required technical problem solved of the utility model can be achieved through the following technical solutions:
A kind of mould for shell cast parts, comprise cup, sprue, screen pack, cross gate, foundry goods, core, rising head, described sprue is connected with cup, described screen pack is positioned on the faying surface of sprue and cross gate, described cross gate is connected with foundry goods by rising head, and described foundry goods is arranged on the surface of core.
Further, described screen pack is Filter-Screen for Molten Iron or fibrous filter net.
Further, described screen pack is designed to square shape.
Further, slag trap is provided with in described screen pack.
Further, described screen pack mould assembling compresses.
Further, described rising head is arranged on the centre of foundry goods.
The beneficial effects of the utility model: a kind of mould for shell cast parts, add rising head in the middle of foundry goods, and molten metal flows into foundry goods die cavity through rising head, avoids the phenomenon occurring seepage, shrinkage porosite or shrinkage cavity and cast(ing) surface bad order between foundry goods and core; Sprue and cross gate faying surface are provided with screen pack, screen pack is effectively removed bubble in molten metal, is pressed from both sides the objectionable impurities such as grey oxide and various field trashes, eliminate the core of foundry goods, slag blister, sand holes, greatly improve the yield rate of foundry goods, improve inherent quality and the presentation quality of foundry goods.
Accompanying drawing explanation
Fig. 1 is the utility model die structure dwg;
Related components symbol description: 1, cup; 2, sprue; 3, screen pack; 4, cross gate; 5, foundry goods; 6, core; 7, rising head.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
During concrete enforcement, composition graphs 1, a kind of mould for shell cast parts, comprises cup 1, sprue 2, screen pack 3, cross gate 4, foundry goods 5, core 6, rising head 7.Sprue 2 is connected with cup 1, and screen pack 3 is positioned at sprue 2 with on the faying surface of cross gate 4, and cross gate 4 is connected with foundry goods 5 by rising head 7, and foundry goods 5 is arranged on the surface of core 6.
Screen pack effectively can be removed bubble in metal bath, press from both sides the objectionable impurities such as grey oxide and various field trashes, thus fundamentally eliminate core, slag blister, the sand holes of foundry goods, greatly improve the yield rate of foundry goods, improve inherent quality and the presentation quality of foundry goods.Screen pack can also improve foundry goods mechanical performance: casting hardness can be made to improve, and the bending strength of all even raising foundry goods of case hardness.Screen pack can be Filter-Screen for Molten Iron or fibrous filter net, and fibrous filter net is high-temperature fibre screen pack.Screen pack can with scissors be cut into the square of arbitrary dimension, be placed on sprue and cross gate faying surface, compress with mould assembling.In order to reach better filter effect, in screen pack, be provided with slag trap.
Be provided with rising head in mould, rising head is arranged on the centre of foundry goods, and molten metal, by cup, sprue, screen pack, cross gate, flows into foundry goods die cavity by rising head.This mould alleviates the labour intensity of post processing employee, enthusiasm and the production efficiency of employee improve greatly, and product appearance and mechanical performance all meet customer requirement, achieve the object enhancing productivity and reduce production cost, considerably increase creativity consciousness and the ability of employee and improve the competitiveness of company in market.
For a mould for shell cast parts, in the middle of foundry goods, add rising head, molten metal flows into foundry goods die cavity through rising head, avoids the phenomenon occurring seepage, shrinkage porosite or shrinkage cavity and cast(ing) surface bad order between foundry goods and core; Sprue and cross gate faying surface are provided with screen pack, screen pack is effectively removed bubble in molten metal, is pressed from both sides the objectionable impurities such as grey oxide and various field trashes, eliminate the core of foundry goods, slag blister, sand holes, greatly improve the yield rate of foundry goods, improve inherent quality and the presentation quality of foundry goods.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
