Abstract
The utility model discloses a kind of metal parts casting mould, the utility model comprises relative cope (1) and drag box (2), casting sand (3) is provided with in cope (1), lower casting sand (4) is provided with in drag box (2), core (5) is provided with, upper casting sand (3) and be provided with gap (6) of casting between lower casting sand (4) and core (5) in upper casting sand (3) and lower casting sand (4); Be provided with down gate (7) in described upper casting sand (3), down gate (7) is connected with runner gate (8), and runner gate (8) is provided with screen pack (9) with casting gap (6).The smooth exquisiteness of cast(ing) surface that the utility model is obtained, greatly increases the quality of foundry goods.
Description
Technical field
the utility model relates to a kind of metal parts casting mould, relates to casting sand production system.
Background technology
the casting cycle of metallic element is, first extrude patrix at cope, counterdie is extruded again at drag box, interior core is set in upper die and lower die, then by relative with drag box for cope closed, and between cope and drag box, form casting gap, also be casting model, then molten iron is poured into casting gap from down gate, treat that molten iron cools, namely obtain mo(u)lded piece.But contain more impurity due to existing molten iron, therefore conveniently the mo(u)lded piece surface that obtains of equipment is comparatively coarse, have impact on the quality of foundry goods.
Utility model content
the purpose of this utility model is, provides a kind of metal parts casting mould.The smooth exquisiteness of cast(ing) surface that the utility model is obtained, greatly increases the quality of foundry goods.
the technical solution of the utility model: a kind of metal parts casting mould, comprise relative cope and drag box, in cope, be provided with casting sand, in drag box, be provided with lower casting sand, be provided with core in upper casting sand and lower casting sand, upper casting sand and lower be provided with between casting sand and core casting gap; Be provided with down gate in described upper casting sand, down gate is connected with runner gate, and runner gate is provided with screen pack with casting gap.
in above-mentioned metal parts casting mould, described screen pack filter bores aperture be 0.2mm-0.8mm.
compared with prior art, the utility model is provided with screen pack between runner gate and casting gap, therefore can filter out the impurity in molten iron, improves the molten iron purity entering casting gap, the smooth exquisiteness of cast(ing) surface that casting obtains, greatly increases the quality of foundry goods.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
embodiment: a kind of metal parts casting mould, form as shown in Figure 1, comprise relative cope 1 and drag box 2, casting sand 3 is provided with in cope 1, lower casting sand 4 is provided with in drag box 2, core 5 is provided with, upper casting sand 3 and be provided with gap 6 of casting between lower casting sand 4 and core 5 in upper casting sand 3 and lower casting sand 4; Be provided with down gate 7 in described upper casting sand 3, down gate 7 is connected with runner gate 8, and runner gate 8 is provided with screen pack 9 with casting gap 6.Described screen pack 9 filter bores aperture be 0.5mm.The utility model is provided with screen pack between runner gate and casting gap, therefore can filter out the impurity in molten iron, improves the molten iron purity entering casting gap, and the smooth exquisiteness of cast(ing) surface obtained of casting, greatly increases the quality of foundry goods.
