Abstract
The utility model relates to an improve knuckle microstructure's special mould, include psammitolite, external mold and the knuckle casting mould die cavity of constituteing by both, knuckle casting mould die cavity contain mutual intercommunication for the main cavity of forming shaft bearing, for fashioned bear first pair of chamber on the arm, for the shaping turn to the arm the vice chamber of second and for the vice chamber of the third that bears the arm under the shaping, first pair of chamber, the vice chamber of second, the vice chamber of third are radial the distribution in proper order in the week of main cavity side, the main cavity between the vice chamber in first pair of chamber, second through advance the hot water piece, water and the pouring basin is linked together, the main cavity through insulation riser between second vice chamber, the vice chamber of third, another advances the hot water piece, another waters and also is linked together with the pouring basin. The utility model discloses a the gating system is rationally distributed, the single -point position of avoiding the knuckle because of thickness too the thin type become the metallography pearlite and exceed standard, effective balanced cooling rate, more ferrites can be appeared in the thin position of divert festival, effectively improve its microstructure.
Description
Technical field
This utility model relates to a kind of particular manufacturing craft improving knuckle metallographic structure.
Background technology
The spot size became uneven complex-shaped, each of knuckle series products, in casting cycle, knuckle series products often becomes metallographic pearlite to exceed standard because of single-point part thickness too thin type, thus also makes hardness exceed standard.
Utility model content
In view of the deficiencies in the prior art, the particular manufacturing craft improving knuckle metallographic structure that technical problem to be solved in the utility model is to provide a kind of reasonable in design, the suitability is good.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of particular manufacturing craft improving knuckle metallographic structure, including core, external mold and the knuckle casting mold die cavity being made up of both, described knuckle casting mold die cavity comprises the main chamber in order to shaping axle bearing being interconnected, the secondary chamber of load bearing arm first in order to molding, in order to the second secondary chamber of molding steering arm and in order to the under molding the 3rd of load bearing arm the secondary chamber, described first secondary chamber, second secondary chamber, 3rd secondary chamber is radially sequentially distributed all sides in main chamber, main chamber is in the first secondary chamber, through entering soup sheet between second secondary chamber, running channel is connected with cup, main chamber is in the second secondary chamber, warm rising head between 3rd secondary chamber, another enters soup sheet, another running channel is also connected with cup.
Preferably, the thickness of the molten iron block of described insulated feeder molding is 2 ~ 4 times of thickness of steering arm of the second secondary chamber molding.
Preferably, the steering arm of secondary chamber molding is thick compared with second for the load bearing arm of the described first secondary chamber molding.
Preferably, described insulated feeder and the second secondary chamber be spaced apart 15 mm ~ 25mm.
Compared with prior art, this utility model has the advantages that running gate system of the present utility model is rationally distributed, the single-point position of knuckle is avoided to exceed standard because of thickness the least formation metallographic pearlite, the steering arm of knuckle thickness smaller part position such as knuckle, load bearing arm, lower load bearing arm, efficient balance rate of cooling, the relatively thin position making knuckle can separate out more ferrite, is effectively improved its metallographic structure.
The utility model is described in more detail with detailed description of the invention below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the organigram of this utility model embodiment.
In figure: 1-enters soup sheet, 2-running channel, 3-cup, 4-insulated feeder.
Detailed description of the invention
For features described above of the present utility model and advantage can be become apparent, special embodiment below, and coordinate accompanying drawing, it is described in detail below.
As shown in Figure 1, a kind of particular manufacturing craft improving knuckle metallographic structure, including core, external mold and the knuckle casting mold die cavity being made up of both, described knuckle casting mold die cavity comprises the main chamber in order to shaping axle bearing being interconnected, the secondary chamber of load bearing arm first in order to molding, in order to the second secondary chamber of molding steering arm and in order to the under molding the 3rd of load bearing arm the secondary chamber, described first secondary chamber, second secondary chamber, 3rd secondary chamber is radially sequentially distributed all sides in main chamber, main chamber is in the first secondary chamber, through entering soup sheet 1 between second secondary chamber, running channel 2 is connected with cup 3, main chamber is in the second secondary chamber, warm rising head 4 between 3rd secondary chamber, another enters soup sheet 1, another running channel 2 is also connected with cup 3.
In this utility model embodiment, the thickness of the molten iron block of described insulated feeder 4 molding is 2 ~ 4 times of the thickness of the steering arm of the second secondary chamber molding.
In this utility model embodiment, the steering arm of secondary chamber molding is thick compared with second for the load bearing arm of the described first secondary chamber molding.
In this utility model embodiment, described insulated feeder 4 and the second secondary chamber be spaced apart 15 mm ~ 25mm.
This utility model is not limited to above-mentioned preferred forms, and anyone can draw other various forms of particular manufacturing crafts improving knuckle metallographic structure under enlightenment of the present utility model.All impartial changes done according to this utility model claim and modification, all should belong to covering scope of the present utility model.
