Description
Technical field
The utility model relates to a kind of small-bore high pound level valve body core for cast, belongs to the technical field that foundry goods is manufactured.
Background technology
In cast steel piece craft design, various technological parameters are all to solidify in order principle calculate and go out.Some height pound level valve body bores are little, wall thickness, in two techniques of the easy appearance of design process, emit and make a slip of the tongue closely, cause hot-spot between two rising heads, affect the normal solidification sequence of steel-casting, thereby produced casting flaw, have been offset casting Technology Design original intention.
Summary of the invention
The utility model object is to provide a kind of small-bore high pound step valve body technology hot-spot problem that solves, and has improved the small-bore high pound level valve body core for cast of steel-casting quality, has solved the problem that prior art exists.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises core body, described core body at least comprises cross one another the first core part and Second-Type core, described the first core part center and Second-Type core center are provided with the steel pipe arbor of being made by seamless steel pipe, the two ends of described steel pipe arbor extend to respectively outside the end of the first core part and outside the end of Second-Type core and form air inlet and gas outlet, and steel pipe arbor forms round part at the infall of the first core part and Second-Type core.The utility model mentality of designing is to use the seamless steel pipe of sufficient intensity specification to do core arbor, seamless steel pipe arbor is foundry goods superheat region by the first core part and Second-Type core, Normal squeezing air between being open to traffic toward seamless steel pipe in 3-5 hour after extremely pouring into a mould from pouring into a mould, by compressed air, adjust the thermograde in foundry goods cooling procedure, improve technique problems of excessive heat and solve the overheated die cavity scab problem causing, thereby solve small-bore high pound step valve body technology hot-spot problem, improved steel-casting quality.
As preferably, described the first core part and the mutual square crossing of Second-Type core.
As preferably, described core body also comprises the 3rd core part, described the 3rd core part is intersected with the first core part and Second-Type core, in the 3rd core part, is provided with solid arbor, and the round part outer wall of one end of described solid arbor and described steel pipe arbor welds together.Wherein, the 3rd core part is difficult for producing hot-spot, therefore solid arbor is set in the 3rd core part.
Therefore, the utlity model has and can solve small-bore high pound step valve body technology hot-spot problem, improved the features such as steel-casting quality.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, core body comprises the first core part 1 and Second-Type core 2, the 3rd core part 3, the first core part 1 and the mutual square crossing of Second-Type core 2, and the 3rd core part 3 is intersected with the first core part 1 and Second-Type core 2.
The first core part 1 center and Second-Type core 2 centers are provided with the steel pipe arbor 4 of being made by seamless steel pipe, the two ends of steel pipe arbor 4 extend to respectively outside the end of the first core part 1 and outside the end of Second-Type core 2 and form air inlet 5 and gas outlet 6, and steel pipe arbor 4 forms round part 7 at the infall of the first core part 1 and Second-Type core 2.In the 3rd core part 3, be provided with solid arbor 8, round part 7 outer walls of one end of solid arbor 8 and steel pipe arbor 4 weld together.
