Abstract
The utility model discloses a lower mold of a circuit board punching mold. The lower mold comprises a lower mold body (2) in which blanking holes (1) are formed, wherein the blanking holes penetrate through the lower mold body from top to bottom, punching ports (3) are formed in the tops of the blanking holes, blanking ports (4) are formed in the bottoms of the blanking holes, the blanking holes are gradually enlarged from the ends of the punching ports to the ends of the blanking ports and are holes with L-shaped integral cross sections which are formed by slitting rectangular holes (5) with short and thick cross sections and rectangular hole (6) with thin and long cross sections, and the lower mold body is provided with two lines of blanking holes, and each line comprises ten blanking holes. Compared with the prior art, the lower mold has the advantages that the blanking holes are gradually enlarged from the ends of the punching ports to the ends of the blanking ports, so that a blanked material has environmental space gradually larger than the volume of the blanking material in the dropping process, the blanking holes are effectively prevented from being blocked, the material clamping is avoided, and the lower mold is stable and reliable in operation and has very high operation efficiency.
Description
Technical field
The utility model relates to the die cutting die field, relates in particular to a kind of counterdie of wiring board die cutting die.
Background technology
The material-dropping hole of existing line plate die cutting die counterdie is big or small identical from top to bottom, its defective is, blanking easily stops up material-dropping hole, and blanking is in a single day stuck in material-dropping hole, then the lighter can't proceed die-cut operation, needs just to work on after the cleaning, trouble consuming time, affects efficient, serious also can affect the mold use life-span, even directly causes its corrupted to be scrapped.
The utility model content
In view of this, technical problem to be solved in the utility model is: provide a kind of material-dropping hole not stop up, do not get stuck, the efficiently counterdie of the wiring board die cutting die of operation of die-cut operation is guaranteed in stable and reliable operation.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of counterdie of wiring board die cutting die, comprise the lower mould body that has material-dropping hole, described material-dropping hole is thoroughly worn described lower mould body from top to bottom and is formed die-cut mouthful in the top, forms blanking port in the bottom, and wherein, described material-dropping hole is enlarged to described blanking port end gradually by the described cut ends of rushing.
As preferably, described material-dropping hole is the hole of L-type for be the rectangular opening of short and thick shape and rectangular opening that cross section the is elongate logical whole cross section that forms each other that slits by cross section.
As preferably, described lower mould body has the described material-dropping hole of two row, and the described material-dropping hole of every row is ten.
As shown from the above technical solution, the beneficial effects of the utility model are:
Compared to existing technology, material-dropping hole of the present utility model enlarges to the blanking port end gradually by rushing cut ends, so that blanking can have increasing environment space in itself volume in the process that falls, guarantees that effectively material-dropping hole does not stop up, do not get stuck, stable and reliable operation, operating efficiency is high.
Description of drawings
Fig. 1 is plan structure schematic diagram of the present utility model.
Fig. 2 is longitudinal cross-section of the present utility model structural representation.
1, material-dropping hole; 2, lower mould body;
3, die-cut mouthful; 4, blanking port;
5, cross section is the rectangular opening of short and thick shape; 6, cross section is the rectangular opening of elongate.
The specific embodiment
In order to make those skilled in the art can further understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing.
See also Fig. 1 to shown in Figure 2, the utility model provides a kind of counterdie of wiring board die cutting die, comprise the lower mould body 2 that has material-dropping hole 1, described material-dropping hole is thoroughly worn described lower mould body from top to bottom and is formed die-cut mouthful 3 in the top, form blanking port 4 in the bottom, wherein, described material-dropping hole is enlarged to described blanking port end gradually by the described cut ends of rushing, described material-dropping hole is the hole of L-type for be the rectangular opening 5 of short and thick shape and rectangular opening that cross section the is elongate 6 logical whole cross sections that form each other that slit by cross section, described lower mould body has the described material-dropping hole of two row, and the described material-dropping hole of every row is ten.In the utility model, described material-dropping hole preferably adopts the mode of line cutting to make, and actinal surface is smooth smooth.
But the above only is better possible embodiments of the present utility model, is not to limit to claim of the present utility model, so the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, all in like manner is included in the scope of the present utility model.
Claims (3)
1. the counterdie of a wiring board die cutting die, comprise the lower mould body (2) that has material-dropping hole (1), described material-dropping hole is thoroughly worn described lower mould body from top to bottom and is formed die-cut mouthful (3) in the top, forms blanking port (4) in the bottom, it is characterized in that described material-dropping hole is enlarged to described blanking port end gradually by the described cut ends of rushing.
2. the counterdie of wiring board die cutting die as claimed in claim 1 is characterized in that, described material-dropping hole slits and leads to the hole that the whole cross section that forms each other is L-type for be the rectangular opening (5) of short and thick shape and rectangular opening (6) that cross section is elongate by cross section.
