Description
Technical field
The utility model relates to the mould of producing hinge, especially a kind of circle hinge mould.
Background technology
The shape of market upper hinge is various, have the various hinges such as circle hinge, flat hinge, penoncel hinge, and the processing and forming of hinge needs specific mould, therefore the size of mould must be very accurate, complete with the hinge arrangement of guaranteeing to produce, dimensional discrepancy is little, can on market, sell.In circle hinge, have trickle change in size, it is more difficult that the mould that therefore circle cuts with scissors is compared other hinges making, due to the restriction of mould, be difficult to reach once complete moulding, forming technique lacks progressive, need to carry out follow-up further processing, extremely costly power and manpower.
Utility model content
The purpose of this utility model is to provide a kind of reasonable in design, and circle is hinged into type mould easily.
What the utility model solved is that existing circle is hinged into mould, and structural design lacks reasonability, is difficult to reach the requirement of once complete moulding, causes the problem of the significant wastage of financial resources and manpower.
The technical scheme that the utility model solves its technical problem employing is: the utility model comprises back-up block and model block,
Described back-up block is nahlock shape, and the upper surface of back-up block is provided with the first cylindrical hole, and lower surface is provided with the second cylindrical hole;
Described model block is nahlock shape, be embedded in the first cylindrical hole of back-up block, the centre position of model block is carved with through hole, the vertical cross-section of through hole is inverted trapezoidal structure, the horizontal structure of through hole is to enclose by the first circle, the second phase tangent line circular and that connect both shape forming, and the length dimension of through hole upper end is greater than the length dimension of through hole lower end; The described first circular and same center of circle of back-up block, the center of circle of the second described circle is along the horizontal symmetrical disalignment of back-up block in the center of circle of the first circle; The lower end of described through hole is provided with changeover portion, and the inwall of changeover portion is parallel with the vertical direction of back-up block.
The beneficial effects of the utility model are: the utility model reasonable in design can process accurately rationally circle hinge size, so that follow-up processing has been removed in the one-shot forming of circle hinge from model block.
