Abstract

The utility model discloses a casting structure used for casting a die-casting machine tail board, which is used in the as-cast production process of small dead heads by nodular cast iron; and by using the casting structure, the defects of looseness and shrinkage cavity of a supporting seat of a thrust block do not easily occur, the compactness of the whole casting can be improved, the quality of the whole tail board can be improved, and the rate of finished products is higher. The casting structure comprises a casting body (1) used for molding the tail board, wherein a bulge (2) used for molding the supporting seat of the thrust block is arranged on the casting body (1); a platform (3) is arranged on the top end of the bulge (2); a plurality of blank pressing dead heads (4) are arranged along the circumferential direction of the platform (3); a plurality of chilling blocks (5) are arranged in the region which is located outside the outer fa.ade of the bulge (2), wherein a distance of 260mm-380mm is arranged between the outer fa.ade and the top surface of the platform (3); and the chilling blocks (5) are distributed along the circumferential direction of the bulge (2).

Description

The casting mold structure that is used for casting die casting machine tailgate
Technical field
The utility model relates to casting technology field, specifically is a kind of casting mold structure for casting die casting machine tailgate.
Background technology
The tailgate that a kind of die casting machine is arranged at present, it has two towering thrust bearing supporting seats, when die casting machine moves, can be subjected to very big impulsive force, quality requirement is higher, yet, in carry out little rising head as cast condition production process with spheroidal graphite cast-iron, shrinkage porosite, shrinkage cavity defect very easily appear in the thrust bearing supporting seat, and then cause whole tailgate to be scrapped, and yield rate is lower.
The utility model content
The technical problems to be solved in the utility model is, provide a kind of in carry out little rising head as cast condition production process with spheroidal graphite cast-iron, not only the thrust bearing supporting seat is not prone to shrinkage porosite, shrinkage cavity defect, and can improve the compactness of whole foundry goods, and then improve the quality of whole tailgate, make the higher casting mold structure that is used for casting die casting machine tailgate of yield rate.
The technical solution of the utility model is, the utility model is used for the casting mold structure of casting die casting machine tailgate, it comprises the casting mold body for the moulding tailgate, the casting mold body is provided with the projection for moulding thrust bearing supporting seat, the projection top is a platform, be circumferentially with a plurality of blank risers along platform, be provided with a plurality of chills in the zone apart from 260 millimeters to 380 millimeters of platform end faces of the outer facade of projection, a plurality of chills circumferentially distribute along projection.
After adopting said structure, the utility model compared with prior art, have the following advantages: because a plurality of chills make the part at first condensation interior apart from the zone of 260 millimeters to 380 millimeters on platform of projection, be called first condensation position temporarily, like this, based on first condensation position, the casting mold body is divided into two parts up and down; Analyze the bottom earlier, when the condensation position still is liquid in the ban, two parts also have contact up and down, the lower part can obtain additional in liquid state cooling contraction process from blank riser, in the ban the condensation position solidify and final process of setting fully in, two parts cut off contact gradually up and down, the lower part can't obtain additional again from blank riser, at this moment, the lower part has been in liquid in solid-state process of setting, utilize the graphitization expansion principle just can make the bottom obtain the more high compactness body of casting, thereby get rid of the shrinkage porosite of bottom, the casting flaw of shrinkage cavity; Then analyze top, when two parts up and down cut off contact gradually, top still can obtain additional from blank riser, yet blank riser is communicated with the position with the casting mold body to be solidified prior to top, the iron liquid of so just the having blocked top passage of back pressure side riser of in the graphitization expansion process of top, being forced, thickness behind this channel condensing is exactly that following blank riser is with the thickness of foundry goods body coupling part, therefore utilize the graphitization expansion principle just can make top obtain the more high compactness body of casting, thereby get rid of the shrinkage porosite on top, the casting flaw of shrinkage cavity; Comprehensively above-mentioned, be circumferentially with a plurality of blank risers along platform, be provided with a plurality of chills in the zone apart from 260 millimeters to 380 millimeters of platform end faces of the outer facade of projection, a plurality of chills circumferentially distribute along projection, such topology layout, purpose is to avoid in the graphitization expansion process iron liquid to be forced back, be respectively equipped with the determined first condensation of chill position, the first condensation channel that blank riser is determined, by working in coordination with of these two settings, make the body of casting that two parts up and down of casting mold body all can obtain, two parts body of casting constitutes whole foundry goods up and down, so the utlity model has in carry out little rising head as cast condition production process with spheroidal graphite cast-iron, not only the thrust bearing supporting seat is not prone to shrinkage porosite, shrinkage cavity defect, and can improve the compactness of whole foundry goods, and then improve the quality of whole tailgate, make the yield rate advantage of higher.
As improvement, two blocks of chills are established in the front of outer facade, and a chill is respectively established in left and right two sides of outer facade; Two blocks of positive chills distribute about front vertical direction center line left-right symmetry, and the span of the distance between these two blocks of chills is closed interval [40 millimeters, 70 millimeters]; Each chill is cuboid, and its length is that 200 millimeters, height are that 100 millimeters, thickness are 80 millimeters; Blank riser amounts to eight, circumferentially evenly distributes along platform; The diameter of blank riser is 120 millimeters, highly be equal to or greater than 600 millimeters, blank riser is [18 millimeters of closed intervals with the span of the thickness of foundry goods body coupling part, 20 millimeters], like this, can more accurately control the condensation time of each several part, thereby when further improving casting quality, the uniformity of each casting quality in guaranteeing to produce continuously.
