Description
Technical field
The utility model is related to a kind of casting technique device, more particularly to a kind of sand mold low pressure casting venting plug.
Background technology
Gas when low pressure casting is poured into a mould in die cavity is heated volumetric expansion, pressure increase, and molten metal can be hindered to flow into die cavity,
Especially its surface can generate oxide-film in the casting process of aluminum alloy melt, improve molten metal surface tension, so that aluminium is closed
Golden liquid mold filling resistance increase；Therefore, the back pressure in die cavity is eliminated as much as, it is to avoid the volume gas in cavity filling process are to reduce defect
Important measures, if being vented bad during moulding by casting, the back pressure in mold cavity can hinder the filling of molten metal, form cast not
The defects such as foot, generation stomata, therefore to be typically vented using venting plug in Foundry Production.
At present, the commodity venting plug series of products of permanent mold casting have been exclusively used in, it have it is easy for installation, can repeatedly profit
With the characteristics of, but poor for the applicability of sand mold low pressure casting, one is that each sand mold low pressure casting needs to use many
This venting plug, is securely arranged on multiple venting plugs not only trouble but also difficult grasp in sand mold；Two are applied to top box sand mold
When covering coating, the venting plug in top box sand mold is easy to be blocked by coating, causes exhaust effect to be deteriorated；Three is cast heel row
Or vent plug is mixed into antiquated sand, or endoporus accompanies scrap metal, it is difficult to reclaim, cause production cost high.
The content of the invention
For above-mentioned situation, the utility model purpose is to provide a kind of sand mold low pressure casting venting plug, and it utilizes group
Existing venting plug usage quantity is more and production cost defect high so as to overcome for box-like venting plug；And overall structure science is closed
Reason, manufacture craft is simple, installs and easy to operate, good exhaust effect, can be prevented effectively from coating and block steam vent, and market prospects are wide
It is wealthy, it is easy to promote the use of.
To realize above-mentioned task, a kind of sand mold low pressure casting venting plug, it includes trapping, upper set, grid；It is described to trap
Cylindrical shape is with upper set, the endoporus of described one end of trapping is provided with step for placing grid, the cylindrical wall of described upper set one end
External screw thread is provided with to be connected with the endoporus of one end of trapping and compress the grid in endoporus of trapping.
To realize the utility model structure, effect optimization, its further step：The grid is in the form of annular discs and its circumference
Center is uniformly distributed multiple steam vents.
Internal diameter φ >=the 50mm for trapping.
External screw thread on the upper cylindrical wall of set is M55 × 4.
The endoporus trapped is additionally operable to equipped casement.
The utility model provides a kind of sand mold low pressure casting venting plug, and it is including trapping, upper set, grid；It is described to trap
Cylindrical shape is with upper set, the endoporus of described one end of trapping is provided with step for placing grid, the cylindrical wall of described upper set one end
External screw thread is provided with to be connected with the endoporus of one end of trapping and compress the technical scheme of the grid in endoporus of trapping；It utilizes combined type
Existing venting plug usage quantity is more and production cost defect high so as to overcome for venting plug, and overall structure is scientific and reasonable,
Manufacture craft is simple, installs and easy to operate, good exhaust effect, can be prevented effectively from coating and block steam vent, with significant warp
Ji benefit and social benefit.
The utility model beneficial effect produced compared to existing technology：
Ith, the utility model uses the technical scheme of Combined exhaust air plug, and it is trapped, upper set and casement are reusable,
General only to change grid, production cost is significantly reduced；
IIth, the utility model uses the technical scheme of Combined exhaust air plug, and it is to coat to apply in top box sand mold that it is integrally assembled
Carried out after material, can effectively prevent coating from blocking steam vent, overall good exhaust effect；
IIIth, using the internal diameter φ >=50mm for trapping, its leaving area is the 3 of outsourcing maximum specification venting plug to the utility model
More than times, the usage quantity of the effectively save venting plug of energy reduces the technology difficulty and production cost of making；
IVth, the utility model overall structure is scientific and reasonable, and manufacture craft is simple, installs and easy to operate, overall exhaust effect
It is really good, production cost is reduced, with significant economic benefit and social benefit.
The utility model is widely used in various casting dies and uses, and is especially suitable for aluminium alloy sand mold low pressure casting and uses.
Below with reference to figure, the utility model is described in further detail.
Brief description of the drawings
The accompanying drawing for constituting the part of the application is used for providing being further understood to of the present utility model, of the present utility model
Schematic description and description is used to explain the utility model, does not constitute to improper restriction of the present utility model.
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is the structural representation of upper set in the utility model.
Fig. 3 is the structural representation of grid in the utility model.
Fig. 4 is the mounting structure schematic diagram trapped with casement in the utility model.
Fig. 5 is the structural representation of casement in the utility model.
In figure：1- traps, and is covered on 2-, 21- external screw threads, 3- grids, 4- casements.
Specific embodiment
Referring to the drawings, the utility model is realized in：A kind of sand mold low pressure casting venting plug, it includes trapping 1,
Above cover 2, grid 3；Described trapping 1 is cylindrical shape with upper set 2, and the endoporus for trapping 1 one end is provided with step for placing lattice
