Abstract
The utility model discloses a limiting iron for a box body core. The limiting iron comprises a cavity and a core, wherein the core is located on the inner side of the cavity; a sand mould is arranged on the outer side of the cavity; limiting irons are arranged at the bottom and on the side wall of the cavity; each limiting iron takes the shape of a cross with a linear shape at the bottom; the protruding part of each limit iron is inserted into the sand mould; each limit iron is located inside the cavity; a riser and a pouring opening are formed in the upper part of the cavity; a shaft in the middle plays a supporting function; the areas of two surfaces are relatively large so as to play a stabilizing function; during the pouring process, the molten steel can be well blended with the limiting irons; as the limiting irons are adopted, the working efficiency of mounting the core is increased by three to four times; the defective rate is quite low and waste products are decreased below 1%; economic benefits are increased by 300 thousand Yuan each year.
Description
Technical field
The utility model relates to a kind of casting field of large-size box, relates in particular to a kind of casing fuse limiting iron.
Background technology
Large-size box is because volume is huge especially, and wall thickness is only 13 millimeters, and extremely difficult grasp in process of production, in the time of lower fuse, if error differs 0.5 ﹪, the consequence causing is exactly scrapping of whole foundry goods, thereby need be placed in the body wall of large-size box with a limiting iron, to guarantee the wall thickness of casing, and can play a supporting role to fuse, and limiting iron can not cause the defect of casing, can fuse into one in when casting and whole casing.
Summary of the invention
The purpose of this utility model is to provide a kind of casing fuse limiting iron, and middle axle plays a supportive role, and two sides area plays more greatly stabilization, and when cast, molten steel energy and limiting iron well merge.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of casing fuse limiting iron, comprises die cavity and fuse, and fuse is positioned at die cavity inner side, the outside of die cavity is sand mold, it is characterized in that: bottom and the sidewall of die cavity are provided with limiting iron, limiting iron be shaped as " soil " word shape, the projection of limiting iron is inserted in sand mold, and limiting iron is positioned at die cavity.The top of described die cavity is provided with rising head and cast gate.
The utility model has the advantages of and be: middle axle plays a supportive role, and two sides area plays more greatly stabilization, when cast, molten steel energy and limiting iron well merge.The use of limiting iron, improved 3-4 doubly, and percent defective is very low for the operating efficiency that fuse is installed, and waste product drops to below 1 ﹪, increases the benefit every year 300000 yuan.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of limiting iron in Fig. 1.
Fig. 3 is the top view of Fig. 2.
In accompanying drawing: 1, rising head; 2, cast gate; 3, die cavity; 4, limiting iron.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The utility model as Figure 1-3, a kind of casing fuse limiting iron, comprise die cavity 3 and fuse, fuse is positioned at die cavity 3 inner sides, the outside of die cavity 3 is sand mold, it is characterized in that: the bottom of die cavity 3 and sidewall are provided with limiting iron 4, limiting iron 4 be shaped as " soil " word shape, the projection of limiting iron 4 is inserted in sand mold, and limiting iron 4 is positioned at die cavity 3.According to described casing fuse limiting iron, it is characterized in that: the top of described die cavity 3 is provided with rising head 1 and cast gate 2.
Operation principle of the present utility model as Figure 1-3, the projection of limiting iron 4 is inserted in sand mold, can fix like this limiting iron 4, and limiting iron 4 plays the effect of support for fuse, thereby guarantee the thickness of die cavity 3, the bottom of die cavity 3 and sidewall are all provided with limiting iron 4, have guaranteed the overall wall thickness of die cavity 3.Molten steel injects from cast gate 2, and wherein limiting iron 4 fuses into one with molten steel.Middle axle plays a supportive role, and two sides area plays more greatly stabilization, and when cast, molten steel energy and limiting iron well merge.The use of limiting iron, improved 3-4 doubly, and percent defective is very low for the operating efficiency that fuse is installed, and waste product drops to below 1 ﹪, increases the benefit every year 300000 yuan.
Embodiment recited above is described preferred embodiment of the present utility model; not design of the present utility model and protection domain are limited; do not departing under the prerequisite of the utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model, all should fall into protection domain of the present utility model.
