The sand mould locating pin combination for casting comprises a locating pin male head and a locating pin female head, wherein the locating pin male head comprises a male head column body with a circular table shaped lower end; a male head annular boss is arranged in the middle part of the male head column body; a plurality of dovetail plates connected with the side surface of the column body are uniformly arranged on the upper surface of the male head annular boss; the locating pin female head comprises a female head column body; a cavity in clearance fit with the circular table shaped lower end of the male head column body is formed in the bottom surface of the female head column body; a female head annular boss is arranged at the lower end of the female head column body; and a plurality of dovetail plates connected with the side surface of the female head column body are uniformly arranged on the upper surface of the female head annular boss. The sand mould locating pin combination for casting is reasonable in design; the modeling practice shows that the sand mould locating pin has a good controlling effect, the locating dimension of the sand mould can be ensured, a casting quality can be improved, and the market demand is met.
Description
Technical field
Sand mold orientation tool when the utility model relates to casting, is specially a kind of casting sand mold alignment pin combination.
Background technology
At present, foundry of company adopts automatic moulding production line after scrap build, drawn on rollover machine delivery, manual mould assembling.Because the ledge cast product dimension precision requirement of colliery underground belt conveyor is higher, foundry goods overall length 1750mm, substance 700kg, center dimensional discrepancy requires, and the outer mud locate mode of traditional sandbox can not meet foundry goods requirement, needs a kind of sand mould positioning device that can accurately locate the upper and lower case of sand mold, require in the situation that sand mold intensity is not high simultaneously, be difficult for vibration skew, can hold molding sand, guarantee the dimensional accuracy of ledge foundry goods.
Summary of the invention
Sand mold orientation tool when the purpose of this utility model is to provide a kind of casting.
The utility model is to adopt following technical scheme to realize:
A kind of casting sand mold alignment pin combination, comprises alignment pin male and alignment pin female;
Described alignment pin male comprises male cylinder, the lower end of described male cylinder is round table-like (being frusto-conical), the middle part of described male cylinder has male annular boss, and described male annular boss upper surface is evenly provided with some coattail boards that are connected with column side face;
Described alignment pin female comprises female cylinder, the bottom surface of described female cylinder has the cavity with the round table-like lower end matched in clearance of male cylinder, the lower end of described female cylinder has female annular boss, and described female annular boss upper surface is evenly provided with some coattail boards that are connected with female column side face.
Before moulding line is joined case, on two casting dies, design respectively male alignment pin fixture and female alignment pin fixture fixes alignment pin male and alignment pin female.The shape of male alignment pin fixture is similar to alignment pin female, and insert in male alignment pin fixture the round table-like lower end of alignment pin male; In like manner, the shape of female alignment pin fixture is similar to alignment pin male, and female alignment pin fixture also has round table-like boss, inserts the cavity of alignment pin female.Before moulding, on two moulds, by fixture, place in advance respectively sand mold alignment pin male and alignment pin female, configure moulding after sandbox, through the sand mold sclerosis of about 40 minutes time, after moulding, alignment pin male and alignment pin female can be embedded in respectively, in two sand molds of nowel, after drawn on rollover machine delivery, because the afterbody design dovetail in alignment pin male and alignment pin female is sand structure, it is coattail board, sand mold alignment pin male and alignment pin female can be fixed on respectively in two sand molds, guarantee not can be when sand mold overturns delivery alignment pin male and alignment pin female drop, after sand mold hardens completely, after upset sand mold top box, locate by sand mold alignment pin with nowel, during last manual mould assembling, on foundry goods, in lower two sand molds, form public, female coordinates location, public by sand mold alignment pin, female has coordinated button case process, etc. to be cast.
The utility model is reasonable in design, by moulding, puts into practice, and this sand mold alignment pin is better sand effect, guarantees the location dimension of sand mold, has improved the product quality of foundry goods, meets the need of market.

Fig. 1 is the structural representation of alignment pin female.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the structural representation of alignment pin male.
Fig. 4 is the upward view of Fig. 3.
In figure, 1-male cylinder, 2-male annular boss, 3-coattail board, 4-female cylinder, 5-female annular boss.
The specific embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
A kind of casting sand mold alignment pin combination, comprises alignment pin male and alignment pin female.
As shown in Figure 3,4, described alignment pin male comprises male cylinder 1, the lower end of described male cylinder 1 is round table-like, and the middle part of described male cylinder 1 has male annular boss 2, and described male annular boss 2 upper surfaces are evenly provided with some coattail boards 3 that are connected with cylinder 1 side; In Practical manufacturing, described alignment pin male can one form.
As shown in Figure 1, 2, described alignment pin female comprises female cylinder 4, the bottom surface of described female cylinder 4 has the cavity with the round table-like lower end matched in clearance of male cylinder 1, the lower end of described female cylinder 4 has female annular boss 5, and described female annular boss 5 upper surfaces are evenly provided with some coattail boards 3 that are connected with female cylinder 4 sides; In Practical manufacturing, described alignment pin female can one form.
During concrete enforcement, design sand mold alignment pin, adopts male and female alignment pin to coordinate button case, alignment pin dimensional tolerance ± 0.2mm, and making the gap between the round table-like lower end of described male cylinder 1 and the bottom surface cavity of female cylinder 4 is 0.2mm; Guarantee the location dimension of sand mold, 1m intermediate channel ledge casting dimension deviation guarantees, at ± 1mm, greatly to have improved the product quality of foundry goods, meets the need of market.
