Abstract
The utility model discloses a kind of valve sand mold casting mold and belong to casting and molding field, be specifically related to a kind of sand mold casting mold.This mould comprises sandbox, sand mold, core and anti-stick coating, and core adopts the auxiliary cored structure of a main core four; Described auxiliary core is centered around main core surrounding, and four auxiliary cores are linked together by the running channel of annular, and ring gate has an opening to be connected on main running channel; Multiple steam vent is provided with on the upside of the core body of described main core; Described anti-stick coating forms the one side of cavity at sand mold and core, is coated in outside sand mold.Processing casting dimension accuracy is poor to adopt the utility model effectively to solve repeatedly, easily produces the defects such as sand washing, burning into sand, pore.
Description
Technical field
The utility model belongs to casting and molding field, is specifically related to a kind of valve sand mold casting mold.
Technical background
The casting method of foundry goods is produced in sand casting in sand mold.Steel, iron and most of non-ferrous alloy casting all can obtain with sand mould casting method.The Modeling Material used due to sand casting is cheap and easy to get, and Casting mold manufacturing is easy, and to the single-piece production of foundry goods, produce by batch and produce in a large number and all can adapt to, for a long time, be the basic technology in Foundry Production always.
At present, valve foundry goods mainly adopts greensand mold dry sand core to cast, and the foundry goods of production is repeatedly finished size precision is poor, and easily produce the defects such as sand washing, burning into sand, pore, meanwhile, the peeling of foundry goods is also effort of taking a lot of work.
Utility model content
The utility model provides a kind of valve sand mold casting mold, and the casting accuracy solving production is poor, produces the problems such as sand washing, burning into sand, sand holes and casting falling sand.
For achieving the above object, the technical solution adopted in the utility model is as follows:
Valve sand mold casting mold, comprises sandbox, sand mold, core and anti-stick coating, it is characterized in that: core adopts the auxiliary cored structure of a main core four; Described auxiliary core is centered around main core surrounding, and four auxiliary cores are linked together by the running channel of annular, and ring gate has an opening to be connected on main running channel; Multiple steam vent is provided with on the upside of the core body of described main core; Described anti-stick coating forms the one side of cavity at sand mold and core, is coated in outside sand mold.
Described sandbox has horn-like sprue gate.
The beneficial effects of the utility model are:
One, adopt the how auxiliary cored structure of a main core, the discreet portions such as the bolt hole of auxiliary core on casting valve, ensure that the disposal molding of foundry goods, avoid repeatedly processing, and improve casting accuracy;
Two, outside sand mold, scribble anti-stick coating, effectively reduce foundry goods burning into sand, the problems such as sand hole, improve casting yield.
Three, on the core body of core, have multiple steam vent, improve the venting quality in casting process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 is sandbox, and 2 is sand mold, and 3 is main core, and 4 is anti-stick coating, and 5 is auxiliary core, and 6 is sprue gate, and 7 is ring gate, and 8 is pore.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is further described.
As shown in Figure 1, valve sand mold casting mold, comprises sandbox 1, and sand mold 2, core and anti-stick coating 4, is characterized in that: core adopts a main core 3 four auxiliary core 5 structure, core has multiple pore 8.Valve sand mold casting mold of the present utility model, sandbox 1 arranges bell mouth shape sprue gate 6, the hidden danger avoiding molten iron to spill bringing.Core adopts the auxiliary cored structure of a main core four, and main core is used for the main body of casting valve, the bolt hole of auxiliary core on casting valve.The valve one-shot forming of producing thus, need not carry out secondary operations auger shell keyhole again, ensure that the precision of valve and attractive in appearance.Be interconnected with ring gate 7 between main core 3 and auxiliary core 5.The upper and lower both sides of main core all have steam vent 8, strengthen exhaust performance.The molding sand building sand mold both can adopt cheap but that effect is poor common green-sand, also can adopt price costly but the good resin sand of effect, was certainly also fine for both are used in combination.The one side forming cavity at molding sand and core coats anti-stick coating, after having built, effectively can reduce knockout when removing sand mold, save knockout treatment step man-hour, enhance productivity.
