Abstract
The invention discloses box core limiting iron, comprising a mold cavity and a core. The core is disposed in the mold cavity; a sand mold is disposed out of the mold cavity; the bottom and the side wall of the mold cavity are provided with limiting iron; the limiting iron is in an earth shape; the convex part of the limiting iron inserts into the sand mold; the limiting iron is disposed in the mold cavity; the upper part of the mold cavity is provided with a sink head and a sprue gate; a shaft at the middle part plays a supporting role; and two surfaces have relatively large area so as to play a stabilizing effect. The molten steel and the limiting iron can be well mixed together during pouring. Due to the use of the limiting iron, work efficiency for installing the core is increased by 3-4 times; waste product rate is extremely low and is reduced to below 1%; and benefit is increased by 300,000 yuan every year.
Description
Technical field
The present invention relates to a kind of casting field of large-size box, relate 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 ensure 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 object of this invention is to provide a kind of casing fuse limiting iron, 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 used in the present invention 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.
Advantageous effect of the present invention is: 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.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
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.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
The present invention 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 invention 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 ensure the thickness of die cavity 3, the bottom of die cavity 3 and sidewall are all provided with limiting iron 4, have ensured 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 the preferred embodiment of the present invention; not design of the present invention and protection domain are limited; do not departing under the prerequisite of design concept of the present invention; various modification and improvement that in this area, common engineers and technicians make technical scheme of the present invention, all should fall into protection scope of the present invention.
