Abstract
The invention discloses a round hinge mold. The round hinge mold comprises a supporting block and a model block, wherein the supporting block is a round block; a first cylindrical hole is formed in the upper surface of the supporting block; a second cylindrical hole is formed in the lower surface of the supporting block; the model block is also a round block and is inlaid in the first cylindrical hole; a through hole is formed in the middle of the model block; the perpendicular section of the through hole has an inverted-trapezoid structure; the level structure of the through hole is formed by enclosing a first circle, a second circle and a tangent line which is connected with the first circle and the second circle; the length of the upper end of the through hole is greater than that of the lower end of the through hole; the first circle and the supporting block share a circle center; the circle center of the second circle is deviated from the circle center of the first circle along a horizontal symmetric center line of the supporting block; a transition section is arranged at the lower end of the through hole; and the inner wall of the transition section is parallel to the perpendicular direction of the supporting block. The round hinge mold is reasonable in structure; one-step forming of round hinges can be realized; the round hinges are machined conveniently; and the production efficiency is improved.
Description
Technical field
The present invention relates to produce the mould of 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 round 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.
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 the requirement of once complete moulding, causes the problem of the significant wastage of financial resources and manpower.
The technical scheme that the present invention solves its technical problem employing 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 horizontal structure of through hole is for enclosing 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 invention has the beneficial effects as follows: reasonable in design of the present invention 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.
