Abstract
The invention relates to a casting mould. The casting mould comprises an upper mould and a lower mould, wherein a pouring gate system is arranged on the upper mould; a mould cavity and a cooling system are arranged on the lower mould; the pouring gate system comprises an inverted truncated-cone-shaped pouring gate channel, a main runner, a buffering channel and a plurality of branch runners; the end, with a smaller sectional area, of the pouring gate channel is connected with one end of the main runner; the cooling system is a cooling liquid channel positioned on the lower mould outside the mould cavity; the mould cavity is surrounded by the cooling liquid channel. According to the casting mould, as the buffering channel is arranged in the pouring gate system, the quality defect of casting products caused by the fact that bubbles are generated by melted iron when high-temperature melted iron is directly injected into the casting mould through a running gate is prevented; in addition, as the cooling liquid channel is arranged on the lower mould outside the mould cavity, and the mould cavity is surrounded by the cooling liquid channel, the casting mould is good in cooling effect, and the casting quality is improved.
Description
Technical field
The present invention relates to casting field, be specifically related to a kind of casting mould.
Background technology
In metallurgy industry, pig mold is the mould for cast iron of casting in iron-smelting process, is widely used in the cast iron equipment of ironmaking enterprise.For great uniform cast iron, traditional casting system has down gate, down gate and ingate UNICOM, high temperature liquid iron directly enters into mould by down gate, such high temperature liquid iron directly enters injection mold cavity, and molten iron easily produces bubble, thus causes the qualitative defect of cast article.
In addition, in the casting of piston blank or the casting process of other parts, cool and coagulation forming fast to make the liquid in casting chamber, general cooling water (oil) pipe that arranges in casting mould inside carries out pressure cooling, but, the install pipeline of water (oil) pipe is more complicated, each pipeline of water (oil) pipe must communicate everywhere, and each pipeline must be provided with Inlet and outlet water (oil) joint, and this adds difficulty with regard to the setting for mold cooling system.
Summary of the invention
For solving the problem, technical problem to be solved by this invention is to provide a kind of casting mould.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of casting mould, comprise upper die and lower die, described patrix is provided with sprue channel open system, described counterdie is provided with die cavity and cooling system, described sprue channel open system comprises pouring head, sprue, buffering road and multiple runner, described pouring head is inverted truncated cone-shaped, one end that described pouring head sectional area is less connects one end of described sprue, the other end of described sprue connects described buffering road, described buffering road connects runner liquid inlet described in each, described in each, runner liquid outlet connects described die cavity,
Described cooling system is be in the cooling passage on the described counterdie outside described die cavity, and described but liquid passage is centered around outside described die cavity.
Further, the cross-sectional area in described buffering road is greater than the cross-sectional area of described sprue and described runner.
Further, described but liquid passage comprise be in described in but the cooling passage inlet at liquid passage two ends and cooling passage liquid outlet.
Further, described cooling passage liquid outlet connects described cooling passage inlet after cooling system.
The invention has the beneficial effects as follows: a kind of casting mould provided by the invention, arranges buffering road in gate system, avoid high temperature liquid iron to be directly injected in mould by down gate, molten iron produces bubble, causes the qualitative defect of cast article.In addition, the described counterdie outside die cavity is provided with cooling passage, and but liquid passage is centered around outside die cavity, good cooling results, improves castability.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
In accompanying drawing, the list of parts representated by each label is as follows:
1, patrix, 2, counterdie, 3, die cavity, 4, pouring head, 5, sprue, 6, buffering road, 7, runner, 8, cooling duct inlet, 9, cooling duct liquid outlet, 10, cooling duct.
Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, a kind of casting mould, comprise patrix 1 and counterdie 2, described patrix 1 is provided with sprue channel open system, described counterdie 2 is provided with die cavity 3 and cooling system, described sprue channel open system comprises pouring head 4, sprue 5, buffering road 6 and multiple runner 7, and described pouring head 4 is tapered, is conducive to molten iron and is injected in die cavity 3 by pouring head 4.One end that described pouring head 4 sectional area is less connects one end of described sprue 5, the other end of described sprue 5 connects described buffering road 6, described buffering road 6 connects runner liquid inlet described in each, runner liquid outlet described in each connects described die cavity 3, and the cross-sectional area cushioning 6 is greater than the cross-sectional area of described sprue 5 and described runner 7.In gate system, arrange buffering road 6, avoid high temperature liquid iron to be directly injected in mold cavity 3 by down gate, molten iron produces bubble, causes the qualitative defect of cast article.
Described cooling system is be in the cooling passage 10 on the described counterdie 2 outside described die cavity 3, and described but liquid path 10 is centered around outside described die cavity 3.Counterdie 2 outside die cavity 3 is provided with cooling passage 10, and but liquid path 10 is centered around outside die cavity 3, and design is better to the cooling effect of molten iron in die cavity 3 like this, improves castability.
Described but liquid path 10 comprise be in described in but the cooling passage inlet 8 at liquid path 10 two ends and cooling passage liquid outlet 9.Described cooling passage liquid outlet 9 connects described cooling passage inlet 8 after cooling system.Cooling fluid, through stating but after liquid path 10, connects described cooling passage inlet 8 from cooling passage liquid outlet 9 after cooling system, and liquid circulation uses, and economizes on resources.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
