Abstract
The utility model discloses a syndromous cast for founding the shell of the welting rolling speed reducer, which comprises a lower type which forms the outer side and the underside of the welting rolling speed reducer, an upper type which forms the top of the welting rolling speed reducer and a middle core which forms the inner cavity of the welting rolling speed reducer, an injection system core is arranged in the upper type, a chart weight is arranged on the lower type. The utility model has the cast with high rigidity; the size of the casting is of high accuracy, the injection system has the effect of feeding. A syndromous cast which is composed of metal mold and water glass sand core is adopted, the utility model improves the rigidity of the cast and the metal mold can recycle, the service life of the utility model can reach more than 1000 times. The utility model has lower production cost, high efficiency, the size of the casting is of high accuracy, which is beneficial for the feeding of the casting.
Description
(1) technical field
The utility model relates to a kind of casting casting mold, particularly a kind of composite mould of cast wheel side reducer shell.
(2) background technology
At present, when cast wheel side reducer shell, generally adopt the greensand mold casting mold.Sand mold is divided into upper and lower case, and loam core of middle employing forms core cavity, is provided with feeding head and running gate system in model circumference one side.And the greensand mold casting mold, the casting mold poor rigidity, the casting poor dimensional precision is unfavorable for feeding.Shrinkage defect often appears in foundry goods, occurs seepage after the processing.
(3) summary of the invention
The technical problems to be solved in the utility model is: a kind of mold stiffness height, casting dimension accuracy height are provided, help the composite mould of the cast wheel side reducer shell of feeding a casting.
In order to solve the problems of the technologies described above, the utility model comprises the intermediate core of the mo(u)ld bottom half that forms hub reduction gear shell lateral surface and bottom surface, the mo(u)ld top half that forms hub reduction gear shell end face and formation hub reduction gear shell inner chamber, be provided with the running gate system core in the mo(u)ld top half, the mo(u)ld top half top is provided with foundary weight.
For the accuracy that improves casting dimension and the service life of casting mold, described mo(u)ld bottom half is a metal mold, and mo(u)ld top half, intermediate core and running gate system core are the waterglass sand mold.
For the ease of the fixing of intermediate core and ventilative, the bottom of described mo(u)ld bottom half is provided with the locating hole of intermediate core, and mo(u)ld bottom half and intermediate core contact site are provided with steam vent.
The beneficial effects of the utility model are: the utility model mold stiffness height, casting dimension accuracy height, running gate system have the feeding effect, the composite mould that adopts metal mold and sodium silicate sand core to form, improved the rigidity of casting mold, metal mold can be reused, reach service life more than 1000 times, production cost is low, the efficient height, the casting dimension accuracy height helps the feeding of foundry goods.
(4) description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1, intermediate core, 2, mo(u)ld top half, 3, the running gate system core, 4, mo(u)ld bottom half, 5, foundary weight, 6, the hub reduction gear shell.
(5) specific embodiment
The NEW TYPE OF COMPOSITE casting mold of a kind of cast wheel side reducer shell as shown in Figure 1, it comprises mo(u)ld bottom half 4, mo(u)ld top half 2, intermediate core 1, running gate system core 3 and foundary weight 5, and mo(u)ld bottom half 4 adopts metal mold, and mo(u)ld top half 2, intermediate core 1, running gate system core 3 adopt the waterglass sand mold.
The bottom of described mo(u)ld bottom half 4 is provided with the locating hole of intermediate core 1, and intermediate core 1 is in the mo(u)ld bottom half 4, and in the locating hole of the lower end of intermediate core 1 on mo(u)ld bottom half 4, mo(u)ld bottom half 4 is provided with steam vent with intermediate core 1 contact site; Mo(u)ld top half 2 is pressed on mo(u)ld bottom half 4 and the intermediate core 1, running gate system core 3 is arranged in the mo(u)ld top half 2, foundary weight 5 is an annular, be pressed on the end face of mo(u)ld top half 2, the inwall of mo(u)ld bottom half 4 forms hub reduction gear shell 6 lateral surfaces and bottom surface, mo(u)ld top half 2 forms the end face of hub reduction gear shell 6, and intermediate core 1 forms the inner chamber of hub reduction gear shell 6.
