Abstract
The utility model discloses a core that small -bore high pound level valve body casting used, including the core body, the core body is at least including a core portion, be equipped with the arbor by the preparation of the hollow steel pipe of pachydermia in the core portion, it has a plurality of gas pocket to open on the pipe wall of arbor, the arbor extends to the core body and is formed with a plurality of gas outlet outward. The utility model discloses a characteristics are that the cost is lower, can avoid that the rising head feeding is not enough, the production of the defect of die cavity scab, and can improve high pound small -bore grade valve body internal quality of casting and surface quality.
Description
Technical field
The utility model relates to the casting field of small-bore high pound level valve body, is specifically related to a kind of core of small-bore high pound level valve body cast casting.
Background technology
Small-bore high pound level valve body due to and bore is little, wall thickness, the region placing rising head is little.Because of the impact of small-bore high pound level valve volume, riser feeding can be caused not enough; Or cause heat to concentrate because the rising head placed is excessive, cause die cavity scab, cannot clear up.
Core in patent document CN203956021U uses seamless steel pipe to do arbor, to cast rear a few hours, in seamless steel pipe arbor, compressed air is led to before cast, by the thermograde in compressed air adjustment foundry goods cooling procedure, solve heat and concentrate the problem with die cavity scab; But in arbor, logical compressed-air actuated operation extremely bothers, and needs exportable compressed-air actuated equipment, and cost is larger.
Summary of the invention
It is lower that the purpose of this utility model is to provide a kind of cost, can avoid the defect of riser feeding deficiency, die cavity scab, and can improve the core of the small-bore high pound level valve body cast casting of the small-bore high pound level valve body internal quality of casting and surface quality.
For achieving the above object, the utility model adopts following technical scheme: a kind of core of small-bore high pound level valve body cast casting, comprise mold core body, described mold core body at least comprises a core part, the arbor made by pachydermia hollow steel pipe is provided with in described core part, the diameter of described arbor is 8 ~ 50mm and the thickness of arbor is 3 ~ 12mm, the tube wall of described arbor has several pores, and described arbor extends to outside mold core body and is formed with several gas outlets.
The utility model adopts pachydermia hollow steel pipe to make arbor, hollow steel pipe outer surface gets through out core, inner chamber does core exhaust passage, by the chill effect of pachydermia hollow steel pipe itself, improve end region, increase the feeding capacity of rising head, the small-bore high pound level valve body internal quality of casting and surface quality can be improved, and it is concentrated to reduce inner chamber heat, avoid scab situation and occur, and cost is lower.Employing diameter is 8 ~ 50mm and the pachydermia hollow steel pipe that thickness is 3 ~ 12mm can ensure its chill effect, and can do arbor.
As preferably, described mold core body comprises the first core part and Second-Type core, the arbor be arranged in the first core part and Second-Type core comprises the first arbor and the second arbor, one end of described second arbor be connected with the tube wall of the first arbor to make the first arbor and the second arbor arranged in a crossed manner to be formed with the first arbor left port, first arbor right output port and the second arbor port, gas outlet is formed outside the end that described first arbor left port extends to the first core part, gas outlet is formed outside the end that described first arbor right output port and the second arbor port extend to Second-Type core.
As preferably, described second arbor port and the first arbor left port and the first arbor right output port are all formed with the angle of 90 degree.
As preferably, described second arbor port and the first arbor left port and the first arbor right output port are formed with specific angle.
Can according to the needs of different cast castings, as two-way valve body, triple-valve body, special angle triple-valve body, the gas outlet of varying number is set and is formed with the arbor of different angles
As preferably, described pore is that multiple row is spaced setting.
As preferably, one end of described second arbor and the tube wall of the first arbor weld together.Should note during welding wanting through welding.
Feature of the present utility model is that cost is lower, can avoid that riser feeding is not enough, the generation of the defect of die cavity scab, and can improve the small-bore high pound level valve body internal quality of casting and surface quality.
figure of description
Fig. 1 is a kind of structure chart of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
The core of the small-bore high pound level valve body cast casting of a kind of threeway as shown in Figure 1, comprise mold core body, mold core body comprises the first core part 1 and Second-Type core 2.First core part 1 and Second-Type core 2 center are provided with the arbor made by pachydermia hollow steel pipe, and the tube wall that arbor comprises the first arbor 3 and the second arbor 4, first arbor and the second arbor all has the pore 9 being spaced setting in multiple row.The diameter of arbor is 20mm, and its thickness is 5mm.
One end of second arbor 4 and the tube wall of the first arbor 3 are welded together to form and have pad 8, first arbor 3 and the second arbor 4 square crossing are also formed with the first arbor left port 5, first arbor right output port 6 and the second arbor port 7, gas outlet is formed outside the end that first arbor left port 5 extends to the first core part 1, gas outlet is formed outside the end that first arbor right output port 6 and the second arbor port 7 extend to Second-Type core 2, second arbor port 7 and the first arbor left port 5 and the first arbor right output port 6 all form angle α, and α is 90 degree.
