The edge of mode positioning mode, cover half mold core and dynamic model mold core is easily broken, and product is easy to appear flash, and quality is difficult to be protected
Card.
Therefore, one kind is studied effectively to solve that mold core edge is not enough caused rupture occur to influence product matter because of aperture space
The method of amount has a very important significance.
Summary of the invention
Present invention aim to address in the prior art use tradition be inserted through mode positioning mode when because aperture space is not enough led
It causes mold core edge the problem of rupture is to influence product quality occur, a kind of active and inactive mold location structure is provided.
In order to achieve the above objectives, the scheme that the present invention uses is as follows:
A kind of active and inactive mold location structure, mainly by the point I of the top surface of dynamic model mold core is arranged in and is arranged in cover half mold core
Bottom surface on point II composition, point I and point II are the two o'clock of male-female engagement, and point I is cusp, and point II is concave point, alternatively, point I is
Concave point, point II are cusp；
The top surface of dynamic model mold core include it is a pair of be parallel to each other while m and while n, the bottom surface of cover half mold core includes a pair of mutually flat
It is capable while p and while q, while m and while the distance between n be equal to while p and while the distance between q, the distance between point I and side m are equal to
The distance between point I and side n, point II with while the distance between p be equal to point II with while the distance between q, face u at the same with side m and
Side n is vertical, and orthographic projection of the point I on the u of face is isosceles right triangle, and the bevel edge of isosceles right triangle is located at dynamic model mold core
Top surface, face v simultaneously with while p and while q it is vertical, orthographic projection of the point II on the v of face is isosceles right triangle, and isosceles right angle three
Angular bevel edge is located at the bottom surface of cover half mold core.
In the prior art to be inserted through positioning frequently with two kinds of structures: a kind of structure is as shown in Fig. 2, dynamic model mold core is inserted into cover half
In mold core, the width of such structural requirement direction y dynamic model mold core along Fig. 2 is less than the width of cover half mold core, otherwise cannot achieve
It is interspersed, when the intracavitary aperture of the type size that x is represented as shown in figure 1 is smaller, it cannot achieve dynamic model mold core and cover half the mold core y along Fig. 2
The width in direction is all smaller, because only that when the width of dynamic model mold core is very small, the width of cover half mold core be possible to it is smaller,
But dynamic model mold core wall thickness is very small at this time, it is difficult to machine-shaping；Another structure is as shown in figure 3, dynamic model mold core top surface is equipped with ladder
Shape cusp, cover half mold core bottom surface are equipped with the trapezoidal groove cooperated with trapezoidal cusp, such structure direction y dynamic model mold core along Fig. 3
Width be equal to the width of cover half mold core, when the intracavitary aperture of the type size that x is represented as shown in figure 1 is smaller, dynamic model mold core and cover half
The width in mold core direction y along Fig. 3 can not be smaller, otherwise can be due to the direction the y cover half mold core bottom wall thickness (i.e. in Fig. 3 along Fig. 3
The region that hacures represent) it is relatively thin, cause the bottom margin of cover half mold core to be easy breakage, it is difficult to machine-shaping.
The present invention efficiently solves by using the positioning of triangle cusp and is inserted through mode positioning using tradition in the prior art
Fa Shiyin aperture space not enough causes mold core edge the problem of rupture is to influence product quality occur, now with triangle cusp position
It is specifically described for dynamic model mold core top surface (principle is identical when triangle cusp is located at cover half mold core bottom surface), triangle point
The comparison diagram with trapezoidal cusp is put as shown in figure 4, figure 4, it is seen that the structure of cusp becomes triangle, wall thickness from trapezoidal
It dramatically increases, the bottom margin due to the relatively thin caused cover half mold core of cover half mold core bottom wall thickness can be solved to a certain extent
