Abstract

The invention discloses a lower die of a die for a punching circuit board. The lower die comprises a lower die body provided with a blanking hole; and the blanking hole is of a structure that a punching cutting edge is formed on the upper section, and a blanking opening is formed on the lower section and penetrates through the lower die body from top to bottom. The blanking opening is gradually expanded from top to bottom and further comprises a fastening piece with a sharp top and a wide bottom; the vertical cross section of the sharp top of the fastening piece is a triangle with two left and right inclined edges; the vertical cross section of the wide bottom of the fastening piece is rectangular; the fastening piece is located inside the blanking opening, and the sharp top is located at the position below the adjacent punching cutting opening; the blanking opening is divided into a left part and a right part which are equal by the fastening piece; and the front end and the back end of the fastening piece are fixedly connected with the lower die body. According to the lower die provided by the invention, due to the structure that the fastening piece is additionally arranged in the blanking opening, the lower die has the advantages of firm supporting point, high strength, no deformation, no collapse and long service life. Furthermore, a user does not need to further additionally arrange dies, the cost is low and the efficiency is high.

Description

Die-cut wiring board lower mould
Technical field
The present invention relates to a kind of wiring board die cutting die, relate in particular to a kind of die-cut wiring board lower mould.
Background technology
Industry is known, die-cut wiring board all will be dug through counterdie self with the material-dropping hole on the lower mould, otherwise die-cut continuous, wiring board will be stuck on the counterdie, particularly in sheet material toughness such as die-cut fiber glass plates preferably during wiring board, this type of situation occurs especially easily, this just causes existing die-cut wiring board to have following defective with lower mould: the strong point fragility, intensity difference, yielding, easily subside, easy fracture, life-span lack, so, the user usually will open two pairs of moulds and process, and cost is high, efficient is low.
Summary of the invention
In view of this, technical problem to be solved by this invention is: a kind of die-cut wiring board lower mould firm, that intensity is high, the life-span is long that supports is provided.
In order to achieve the above object, the present invention adopts following technical scheme to realize:
A kind of die-cut wiring board lower mould, comprise the lower mould body that has material-dropping hole, described material-dropping hole is that epimere forms die-cut cutting edge, the structure that hypomere forms blanking port and thoroughly wears described lower mould body from top to bottom, wherein, described blanking port from top to bottom extends out gradually, also comprise and have the pinnacle, the girth member at the wide end, the longitudinal cross-section on described girth member pinnacle be have about the triangle of two hypotenuses, the longitudinal cross-section at the wide end of described girth member is rectangle, described girth member is positioned at described blanking port, described pinnacle is positioned at the position of contiguous described die-cut cutting edge below, and the two parts that equate about described girth member is divided into described blanking port and rear and front end and described lower mould body are fixedly linked.
As preferably, the cross section of described material-dropping hole is " n " shape.
As preferably, the height of described lower mould body and material-dropping hole upward and downward is all 2 mutually to 2.5mm, the height of described die-cut cutting edge upward and downward is 2 to 2.5mm, described pinnacle is positioned at the position of below, plane, described lower mould body end face place vertical range 6mm, about described girth member to width be 6mm, the distance that extends out of each side outer wall of described blanking port bottom is 3 to 4mm.
As shown from the above technical solution, the invention has the beneficial effects as follows:
Compared to existing technology, the present invention is by setting up the structure of girth member in blanking port, make its have firmly the strong point, intensity large, indeformable, do not subside, do not rupture, the life-span is long.In addition, the user also need not separately many molds, and cost is low, efficient is high.

The specific embodiment
In order to make those skilled in the art can further understand feature of the present invention and technology contents, see also following about detailed description of the present invention and accompanying drawing.
See also Fig. 1 to shown in Figure 2, shade partly is die-cut cutting edge, the invention provides a kind of die-cut wiring board lower mould, comprise the lower mould body 2 that has material-dropping hole 1, described material-dropping hole is that epimere forms die-cut cutting edge 3, the structure that hypomere forms blanking port 4 and thoroughly wears described lower mould body from top to bottom, wherein, described blanking port from top to bottom extends out gradually, also comprise and have pinnacle 5, the girth member 7 at the wide end 6, the longitudinal cross-section on described girth member pinnacle be have about the triangle of two hypotenuses, the longitudinal cross-section at the wide end of described girth member is rectangle, described girth member is positioned at described blanking port, described pinnacle is positioned at the position of contiguous described die-cut cutting edge below, the two parts that equate about described girth member is divided into described blanking port and rear and front end and described lower mould body are fixedly linked, the cross section of described material-dropping hole is " n " shape, the height of described lower mould body and material-dropping hole upward and downward is all 2 mutually to 2.5mm, the height of described die-cut cutting edge upward and downward is 2 to 2.5mm, described pinnacle is positioned at the position of below, plane, described lower mould body end face place vertical range 6mm, it is fixed to come according to the special-shaped slot of wiring board to the width at width position place about described die-cut cutting edge, about described girth member to width be 6mm, the distance that extends out of each side outer wall of described blanking port bottom is 3 to 4mm.
But the above only is better possible embodiments of the present invention, is not to limit to claim of the present invention, thus the equivalent structure that all utilizations specification of the present invention and accompanying drawing content are done variation, all in like manner within the scope of the present invention.
