Abstract

The utility model belongs to the field of mold equipment, relating to a detachable mold. The detachable mold comprises a 20CrNiMo mold body which is formed by at least two parts of an equally-divided circle. The detachable mold provided by the utility model can be used for pouring products with complex shapes, is easy to demold and meanwhile can increase the utilization rate of production materials.

Description

Collapsible mold

Technical field

The utility model belongs to the die apparatus field, relates to a kind of collapsible mold.

Background technology

The centrifugal casting mould therefor all is monoblock type usually, and this mould has determined the necessary simple shape of pourable product, but and direct demold, just powerless for the foundry goods of complex contour.Simultaneously in process of producing product, the product material utilization rate that centrifugal casting is come out is low, and reason is that the material that later stage turning falls is more; And directly make mould the shape of similar products profile, but be difficult to the demoulding.

The utility model content

According to above deficiency of the prior art, the utility model technical problem to be solved is: a kind of collapsible mold is provided, can pour into a mould complex-shaped product, and the demoulding is easy.

The utility model solves the technical scheme that its technical problem adopted: a kind of collapsible mold is provided, comprises the 20CrNiMo mold, the 20CrNiMo mold is that two parts at least of Equal round constitute.

The 2-9 that described 20CrNiMo mold is an Equal round partly constitutes.

The utility model is processed into the mould of detachable to mould from monoblock type, when casting the 20CrNiMo mold is assembled into integral body, and after casting is accomplished the 20CrNiMo mold being split can the smooth demoulding.It is material that collapsible mold adopts 20CrNiMo, and durability is strong, and obviously prolong service life than before.

The profile of needs as the case may be and different cast products, cutting apart angle and can adjusting of 20CrNiMo mold is that 180 degree, fFour piece type are that 90 degree, six lobe formulas are 60 degree like two lobe formulas; The angle of cutting apart is more little, and the shape of pourable product just can be more complicated; If the product design of centrifugal casting is simpler, can adopt the bigger angle of cutting apart.

The beneficial effect that the utility model had is: a kind of collapsible mold is provided, can pours into a mould complex-shaped product, the demoulding is easy, can improve the utilization rate of producing material simultaneously.

The specific embodiment

Embodiment to the utility model further describes below in conjunction with accompanying drawing:

Be depicted as the collapsible mold of producing a kind of nickel chromium molybdenum copper high strength size rolls like Fig. 1-7, comprise the 20CrNiMo mold, the 20CrNiMo mold is divided into three parts by 120 degree, is followed successively by parts 1, parts 2 and parts 3.

When carrying out centrifugal casting and producing, parts 1, parts 2 and the parts 3 of 20CrNiMo mold are assembled and carry out mold production, after casting is accomplished the 20CrNiMo mold being split can the smooth demoulding.

Produce same a kind of nickel chromium molybdenum copper high strength size rolls, the blank weight that adopts former technology to cast out is 750Kg, and weight is 374.5Kg after the machined, and stock utilization is 50%; And the blank weight that casting is come out after the employing collapsible mold is 604Kg, and weight is 374.5Kg after the machined, and stock utilization is 62%.By contrast, a nickel chromium molybdenum copper of every production high strength size rolls gets final product economical with materials 146Kg, and stock utilization has improved 12% than originally.

This shows the collapsible mold that adopts the utility model to provide, it is easy to produce like the complex-shaped product and the demoulding such as nickel chromium molybdenum copper high strength size rolls, can improve the utilization rate of producing material simultaneously.

Claims

1. a collapsible mold comprises the 20CrNiMo mold, it is characterized in that: the 20CrNiMo mold is that two parts at least of Equal round constitute.

2. collapsible mold according to claim 1 is characterized in that: the 20CrNiMo mold is that the 2-9 of Equal round partly constitutes.
