Abstract
The utility model discloses a mud-core framework for casting, comprising framework body, wherein a plurality of fixed stiffeners are connected on the framework body; at least two connection locations with the framework body are arranged on the stiffeners; and the connection locations of the stiffeners and the framework body are connected through screws. According to the utility model, the framework is manufactured by using nodular cast iron; the framework body and the stiffeners are connected through screws; and the problem of easy deformation in the using process is solved.
Description
Technical field
The utility model relates to casting field, and the loam core skeleton is used in particularly a kind of casting.
Background technology
During casting in order to forming the foundry goods internal cavities, the core sand that often is made into by sand grains and binding agent (like clay, tung oil or resin etc.), craft or machine (like core blower, core shooter etc.) are processed in core box.Core box is processed with timber or metal.Core generally needs through oven dry, and device is in casting mold, after molten metal pours into condensation before casting; When shaking out it is removed, in foundry goods, can form cavity, for increasing core strength; Usually in core, settle skeleton, claim by " bone core ", bone core commonly used is the plain cast iron material; And fixing with the screw-thread steel welding usually on the skeleton, flexible distortion.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of not yielding casting to use the loam core skeleton.
The utility model for the technical scheme that solves its technical problem and adopt is: the loam core skeleton is used in a kind of casting; Comprise the skeleton main body; Be connected with the stiffener of plurality of fixed on the said skeleton main body; At least with the skeleton main body two junctions are arranged on the stiffener, said stiffener is connected through screw with the junction of skeleton main body.
As the further improvement of the utility model, said skeleton main body and stiffener are spheroidal graphite cast-iron.
The beneficial effect of the utility model is: compare with existing skeleton, the utility model adopts spheroidal graphite cast-iron to process skeleton, and adopts screw to be connected between skeleton main body and the stiffener, has solved yielding problem in the use.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is done further to detail below, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Fig. 1 has shown a kind of embodiment of casting with the loam core skeleton of the utility model: comprise skeleton main body 1; Be connected with the stiffener 2 of plurality of fixed on the said skeleton main body 1; At least with skeleton main body 1 two junctions are arranged on the stiffener 2; Said stiffener 2 is connected through screw 3 with the junction of skeleton main body 1, and said skeleton main body 1 is a spheroidal graphite cast-iron with stiffener 2.
