Description
Technical field
The present invention relates to the mould producing hinge, especially a kind of circle hinge mould.
Background technology
The various shapes of market upper hinge, have the various hinge 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 to guarantee the hinge arrangement produced, dimensional discrepancy is little, can commercially sell.Circle hinge has trickle change in size, and the mould that therefore circle cuts with scissors is compared other hinges and is made more difficult, due to the restriction of mould, be difficult to reach once complete shaping, forming technique lacks progressive, needs to carry out follow-up further processing, extremely costly power and manpower.
Summary of the invention
The object of this invention is to provide a kind of reasonable in design, circle is hinged into type mould easily.
What the present invention solved is that existing circle is hinged into mould, and structural design lacks reasonability, is difficult to reach once complete shaping requirement, causes the problem of the significant wastage of financial resources and manpower.
The technical scheme that the present invention solves the employing of its technical problem is: the present invention includes 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 shape of horizontal structure for being enclosed by the phase tangent line of both the first circle, the second circle and connection of through hole, 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 invention has the beneficial effects as follows: reasonable in design of the present invention, rationally circle hinge size can be processed accurately in model block, so that the one-shot forming of circle hinge, eliminate follow-up processing.
