Abstract
The utility model discloses a precision-casting deformation-prevention mold. A mold cavity of a mold body is internally provided with riser cavities; and the periphery of each riser cavity is provided with tie bar cavities. The mold structure is easy to implement, and also can effectively solve the problem of deformation caused by stress, thus improving the product yield and the production efficiency.
Description
Technical field
The utility model relates to a kind of precision casting mould structure, in particular, relates to the mould structure of casting circle plate casting with lost-wax process.
Background technology
In casting field, the light casting that lost-wax casting is had relatively high expectations mainly for the production of surface quality, along with the development of lost-wax casting technology, the single product quality that lost-wax casting is produced also promotes thereupon, by several kilograms to tens kilograms of original single-pieces, even there is single-piece to surpass 100 kilograms; The single products quality of producing in lost-wax casting is in the process of middle development, and the problem that the deficiency of lost wax process self is brought also slowly comes out.
When producing the circle plate casting product, because of in casting process, because the wax-loss casting process aspect, the sprue gate is large and concentrated, thereby stress is larger, and foundry goods can produce random distortion.Be out of shape seriously, even product can not process, and produces waste product.This class circle plate casting problem on deformation is solution not yet at present.
The utility model content
Technical problem to be solved in the utility model is to realize a kind of mould structure that can avoid coiling class casting casting process torsional deformation.
To achieve these goals, the technical solution adopted in the utility model is: a kind of essence casting anti-deformation mould, and be provided with in the die cavity of die ontology and emit the oral cavity, the described oral cavity that emits is provided with the lacing wire chamber all around.
The bar shaped cavity that described lacing wire chamber emits the oral cavity diameter to stretch out and is communicated with it for the edge.
Described lacing wire chamber is provided with four and be symmetrically set in and emit around the oral cavity.
The utility model has the advantage of that mould structure is easy to realize, and effectively structure stress and the problem on deformation that causes, the raising product percent of pass has improved production efficiency.
Description of drawings
The below is briefly described the content of every width of cloth accompanying drawing expression in the utility model specification and the mark among the figure:
Fig. 1,2 is the casting die structural representation
Mark among the above-mentioned figure is: 1, die ontology; 2 die cavitys; 3, emit the oral cavity; 4, lacing wire chamber.
The specific embodiment
Referring to Fig. 1,2 as can be known, the die ontology 1 of essence casting anti-deformation mould is dish class mould, emit oral cavity 3 for what feeding was provided with depression in die cavity 2, the stress influence that produces in order to eliminate the running gate system contraction distortion, around emitting oral cavity 3, be provided with lacing wire chamber 4, the bar shaped cavity that lacing wire chamber 4 emits oral cavity 3 diameters to stretch out and be communicated with it for the edge, four lacing wire chambeies 4 preferably are set and are symmetrically set in and emit around the oral cavity 3, lacing wire chamber 4 structures of utilizing this to emit oral cavity 3 and matching, so that casting foundry goods out has rising head and lacing wire structure, lacing wire can be played the effect that disperses casting stress, can not produce at foundry goods again the casting flaws such as shrinkage porosite, prevents that distortion from occurring.
The above has carried out exemplary description to the present invention by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving design of the present invention and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
Claims (3)
1. an essence casting anti-deformation mould is provided with in the die cavity (2) of die ontology (1) and emits oral cavity (3), and it is characterized in that: the described oral cavity (3) that emits is provided with lacing wire chamber (4) all around.
2. essence casting anti-deformation mould according to claim 1 is characterized in that: the bar shaped cavity that described lacing wire chamber (4) emits oral cavity (3) diameter to stretch out and be communicated with it for the edge.
