The casting pattern comprises a sand box with a casting opening, wherein a filter screen is arranged at the casting opening, the sand box is internally provided with upper and lower symmetrical casting cavities, a feeder head is arranged in the middle on the side of the sand box, molten iron is introduced into the casting cavities through the feeder head, at least one internal chill is arranged at the thermal center inside each casting cavity, the internal chill is internally provided with a plurality of cavities, a plurality of through holes are formed in the walls of the cavities, a plurality of cooling media which can flow in the cavities are stored in the cavities, and a plurality of external chills are arranged outside the casting cavities. According to the casting pattern provided by the utility model, the feeder head is arranged on the side of the sand box and the position of the feeder head is adjusted. In addition, the plurality of internal chills are arranged at the thermal center inside the casting cavities and each internal chill is internally provided with a plurality of cavities, and the chills have the chilling and cooling effect on the inner surface, so that the casting deficiency of shrinkage cavity and shrinkage porosity at the thermal center can be eliminated, and the yield is increased.
Description
Technical field
The utility model belongs to sand casting field, is a kind of casting pattern of casting pig hub shell specifically.
Background technology
Sand casting---in sand mold, produce the casting method of foundry goods.Steel, iron and most of non-ferrous alloy casting all can obtain with sand mould casting method.Because the Modeling Material that sand casting is used is cheap and easy to get, Casting mold manufacturing is easy, and single-piece production to foundry goods, produce by batch and produce and all can adapt in a large number, for a long time, be the basic technology in Foundry Production always.
Sand casting is widely used in the moulding manufacture of various ironcastings, mainly, by sandbox with the vertical straight running channel of casting gate, establishes casting mold cavity in sandbox.With the example that is cast into of casting pig wheel hub, the quality of wheel hub quality directly affects traffic safety, because it is in service in specific position at car, is bearing complicated alternate load, and service condition is severe.Conventionally there is defects such as there being more serious loose, shrinkage cavity in thick large variable cross-section accumulated heat joint section in present wheel hub, therefore, provide a kind of casting pattern of casting pig hub shell of the shrinkage cavity and porosity casting flaw of eliminating heat energy-saving position to become those skilled in the art's problem demanding prompt solution.
Utility model content
For the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of casting pattern of casting pig hub shell, can eliminate the shrinkage cavity and porosity casting flaw of heat energy-saving position.
The utility model solves the technical scheme that its technical problem adopts: a kind of casting pattern of casting pig hub shell, comprise the sandbox with casting gate, described casting gate is provided with screen pack, in described sandbox, be provided with 2 laterally zygomorphic casting mold cavities, the side centre position of described sandbox is provided with rising head, iron liquid is introduced described casting mold cavity by described rising head, inside described casting mold cavity, thermal center place arranges at least one internal densener, described internal densener inside is provided with multiple cavitys, the chamber wall of described cavity is provided with some through holes, the cooling medium that in described cavity, storage can be mobile in multiple cavitys, described casting mold cavity is provided with multiple external chills outward.
Preferably, between described external chill and described casting mold cavity, being provided with layer of sand is separated by.
Preferably, described layer of sand is 10～15mm.
Preferably, the surface of described internal densener is provided with air channel.
Preferably, described internal densener is provided with furane resins layer, and described furane resins layer is provided with overlay film layer of sand.
Preferably, the thickness of described overlay film layer of sand is 5～10mm.
Preferably, described internal densener is provided with positioner for internal densener is fixed.
The utility model is provided with rising head by sandbox side, regulate the position of rising head, in addition, inside casting mold cavity, multiple internal denseners are placed at thermal center place, each internal densener inside is provided with multiple cavitys that have cooling medium, chill has the effect of Quench cooling at inner surface, can eliminate the shrinkage cavity and porosity casting flaw of heat energy-saving position, has improved yield rate.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the casting pattern of the utility model casting pig hub shell.
Number in the figure is described as follows:
1, sandbox; 2, casting gate; 3, screen pack; 4, casting mold cavity; 5, rising head; 6, internal densener; 7, cavity; 8, external chill.
Detailed description of the invention
