Abstract
The utility model provides a precoated sand shell mold, belonging to the technical field of casting, and solving the problems that a sand mold manufactured by adopting green sand needs manual molding and has the defects of low efficiency, low yield, difficultly mastered casting mold strength and low casting yield. The precoated sand shell mold mainly comprises a mold case, wherein reinforcing rib grooves are uniformly distributed in the mold case; a base is arranged at the bottom of the mold case; a sand core is arranged in the mold case and is matched with the base; an upper cover is arranged on the top of the mold case. The precoated sand shell mold is mainly used for casting a sand case.
Description
Technical field
The utility model belongs to casting technology field, specifically, relates in particular to a kind of precoated sand shell mould.
Background technology
In casting field, traditional sandbox adopts steel plate to be made usually, easily distortion in use procedure, and the sandbox that adopts the cast iron cast to form, its sand mold adopts damp film sand hand moulding to make usually, inefficiency, yield rate is lower; Tide film sand is to do adhesive with bentonite, then adds water and other additives and mix and form, the sand mold of making of damp film sand, and mould strength is not easy grasp, and, due to damp film sand sand mold high humidity, casting yield is lower.
Summary of the invention
Need hand moulding in order to solve the sand mold that available technology adopting tide film sand makes, inefficiency, yield rate are lower, and mould strength is not easy to grasp, the defect that casting yield is lower, and the utility model provides a kind of precoated sand shell mould.
The utility model is achieved through the following technical solutions:
A kind of precoated sand shell mould, comprise molding box, uniform reinforcement groove in molding box, and the molding box bottom is provided with base, is provided with core in molding box, and core coordinates with base, and the molding box top is provided with upper cover.
Described molding box, base, core and upper cover all adopt precoated sand to be made.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts precoated sand to make, and molding box, base, core and upper cover all can be mass, and qualification rate is high, and dimensional accuracy is guaranteed, after assembling, can use, and has improved production efficiency, and the dimensional accuracy of foundry goods is higher, and yield rate is high.
