Abstract
The utility model provides a be used for special -shaped sacrificial anode casting mould, includes: a lower mould, the last mould that matches with the lower mould wherein, are equipped with a trapezoidal cavity, wing shape cavity two parts on the lower mould, one end that should last mould is equipped with a charge door, these lower mould both ends are equipped with the end cap that is used for the assembly of U type seamless steel pipe iron core respectively, and the higher authority of going up the mould is equipped with several rings installation screw. The utility model discloses not only can cast the waste of the extra large oily engineering construction that has significantly reduced to special -shaped sacrificial anode, and, can also reduce weight, the heat -retaining of mould, improved the intensity of mould greatly.
Description
Technical field
The utility model relates to casting mould, particularly relates to a kind of for special-shaped sacrificial anode casting mould.Belong to mechanical manufacturing field.
Background technology
Cathodic protection is the important method preventing marine steel iron construction from corroding, and more the structure being especially in submerged zone is adopted and protected in this way, and the cathodic protection of sacrificial anode is the simplest, most convenient, the safest, the most effective anti-corrosion method.
When carrying out cathodic Protection Design, protecting current density is one of very important parameter, and the protecting current density needed for the steel construction of different times differs greatly.Usually, the degasification protecting current density design load that polarizes is about 2 times of average protecting current density design load in the whole steel construction time limit in service life.Although, during this period of time relative to whole steel construction service life very short, it is very significant for the service life of steel construction and the impact of antiseptic effect.
Because the conventional cross section of sacrificial anode is: rectangle or trapezoidal, when carrying out preservative treatment, need excessive sacrificial anode is installed in the early stage, to ensure that initial polarization electric current is enough large; First after date is the overprotection avoiding excessive sacrificial anode to bring, then need the method utilizing series resistance, current density lowered.And after the anode material about making about half like this polarizes in the early stage, consumed by series resistance.Therefore, this mode not only can cause surprising waste, and excessive use sacrificial anode, the increase of the platform load that also can cause, so, cause to carry out enhancing design to jacket, the waste caused thus is very large.
In order to solve the problem, the wing that can increase surface area rate of change is extended in traditional rectangular or laddershaped matrix top, to add the changing value of surface area, so, sacrificial anode initial stage current density can be improved, but, existing for rectangle or trapezoidal sacrificial anode mold, due to the change of its shape, the sacrificial anode with wing cannot be cast.Therefore, need one badly and differ from rectangle or trapezoidal sacrificial anode mold.
Utility model content
Main purpose of the present utility model is the above-mentioned shortcoming overcoming prior art existence, and provides a kind of for special-shaped sacrificial anode casting mould, and it can not only be cast special-shaped sacrificial anode, greatly reduces the waste of extra large oily engineering construction; And, the weight of mould, heat accumulation can also be reduced, substantially increase the intensity of mould.
The purpose of this utility model is realized by following technical scheme:
A kind of be used for special-shaped sacrificial anode casting mould, comprise: a counterdie, the patrix matched with counterdie, is characterized in that: counterdie is provided with a ladder cavity, wing shape cavity two parts, and one end of this patrix is provided with a charge door; These counterdie two ends are respectively equipped with the plug for U-shaped seamless steel pipe iron core assembly, are provided with several suspension ring installation screw above patrix.
The surrounding of described counterdie is provided with several reinforcement, several suspension hook; And the overall wall thickness of counterdie is different to reduce mould heat accumulation.
The thickness of described patrix is: 20 ~ 100mm; The charging aperture of one end of patrix is provided with a cover plate, and suspension ring installation screw is located at above cover plate.
The cross sectional shape of described plug is: the T-shaped coordinated with U-shaped seamless steel pipe iron core.
Described upper die and lower die, plug are that cast iron materials is made.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, and it can not only be cast special-shaped sacrificial anode, greatly reduces the waste of extra large oily engineering construction; And, the weight of mould, heat accumulation can also be reduced, substantially increase the intensity of mould.
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
