Abstract
The present invention relates to a kind of small-bore high pound level valve body core for cast, belong to the technical field that foundry goods manufactures.It comprises mold core body, described mold core body at least comprises cross one another first core part and Second-Type core, described first core part center and Second-Type core central are provided with the steel pipe arbor be made up of seamless steel pipe, form air inlet and gas outlet outside the end that the two ends of described steel pipe arbor extend to the first core part respectively and outside the end of Second-Type core, steel pipe arbor forms round part at the infall of the first core part and Second-Type core.
Description
Technical field
The present invention relates to a kind of small-bore high pound level valve body core for cast, belong to the technical field that foundry goods manufactures.
Background technology
In cast steel piece craft design, various technological parameter is all solidify principle in order calculate and go out.Some high pound level valve body bores are little, wall thickness, easily occur that two techniques are emitted and make a slip of the tongue closely, cause hot-spot between two rising heads, affect the normal solidification sequence of steel-casting, thus create casting flaw, offset by casting Technology Design original intention in design process.
Summary of the invention
The object of the invention is to provide one can solve small-bore high pound step valve body technology hot-spot problem, improves the small-bore high pound level valve body core for cast of steel-casting quality, solves prior art Problems existing.
Above-mentioned technical purpose of the present invention mainly solves by the following technical programs: it comprises mold core body, described mold core body at least comprises cross one another first core part and Second-Type core, described first core part center and Second-Type core central are provided with the steel pipe arbor be made up of seamless steel pipe, form air inlet and gas outlet outside the end that the two ends of described steel pipe arbor extend to the first core part respectively and outside the end of Second-Type core, steel pipe arbor forms round part at the infall of the first core part and Second-Type core.Mentality of designing of the present invention uses the seamless steel pipe of sufficient intensity specification to do core arbor, seamless steel pipe arbor is by the first core part and Second-Type core and foundry goods superheat region, front to pouring into a mould in latter 3-5 hour the Normal squeezing air between being open to traffic toward seamless steel pipe from cast, by the thermograde in compressed air adjustment foundry goods cooling procedure, improve technique problems of excessive heat and solve the overheated die cavity scab problem caused, thus solve small-bore high pound step valve body technology hot-spot problem, improve steel-casting quality.
As preferably, described first core part and the mutual square crossing of Second-Type core.
As preferably, described mold core body also comprises the 3rd core part, described 3rd core part is intersected with the first core part and Second-Type core, is provided with solid arbor in the 3rd core part, and one end of described solid arbor and the round part outer wall of described steel pipe arbor weld together.Wherein, the 3rd core part not easily produces hot-spot, therefore arranges solid arbor in the 3rd core part.
Therefore, the present invention has can solve small-bore high pound step valve body technology hot-spot problem, improves the features such as steel-casting quality.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment 1: as shown in Figure 1, mold core body comprises the first core part 1 and the square crossing mutually of Second-Type core 2, the 3rd core part 3, first core part 1 and Second-Type core 2, and the 3rd core part 3 is intersected with the first core part 1 and Second-Type core 2.
First core part 1 center and Second-Type core 2 center are provided with the steel pipe arbor 4 be made up of seamless steel pipe, form air inlet 5 and gas outlet 6 outside the end that the two ends of steel pipe arbor 4 extend to the first core part 1 respectively and outside the end of Second-Type core 2, steel pipe arbor 4 forms round part 7 at the infall of the first core part 1 and Second-Type core 2.Be provided with solid arbor 8 in 3rd core part 3, one end of solid arbor 8 and round part 7 outer wall of steel pipe arbor 4 weld together.
Claims (2)
1. a small-bore high pound level valve body core for cast, comprise mold core body, it is characterized in that described mold core body comprises the first core part, Second-Type core and the 3rd core part, described first core part and Second-Type core are in mutually arranged in a crossed manner, described first core part center and Second-Type core central are provided with the steel pipe arbor be made up of seamless steel pipe, air inlet and gas outlet is formed outside the end that the two ends of described steel pipe arbor extend to the first core part respectively and outside the end of Second-Type core, steel pipe arbor forms round part at the infall of the first core part and Second-Type core, described 3rd core part is intersected with the first core part and Second-Type core, solid arbor is provided with in 3rd core part, one end of described solid arbor and the round part outer wall of described steel pipe arbor weld together.
