Abstract
The utility model provides a prevent waste material stifled hole lower die structure, including the lower mould edge of a knife and lower mould, lower die structure has the waste material hole, the waste material hole is including the last vertical hole that link up the lower mould edge of a knife, the lower vertical hole of lower mould upper portion and last vertical hole intercommunication and the lower mould lower part and the decurrent inclined hole of discharge gate of lower vertical hole intercommunication, all be equipped with the mounting hole on the both sides wall of last vertical hole edge length direction of lower mould edge of a knife, install the slope stick in two mounting holes, the one side of discharge gate is kept away from in the last vertical hole that this slope stick is located the lower. The utility model discloses owing to adopt foretell structural design, under the effect of stick that inclines when the waste material drops, the waste material is kept away from discharge gate one end and is received the waste material that stops that the stick that inclines makes and be close to discharge gate one end at first downwards, and then makes the waste material take place to incline along the discharge gate ejection of compact, avoids the waste material card that the irregular upset of waste material leads to in the waste material hole, guarantees the continuity and the mould safety of production.
Description
Technical Field
The utility model belongs to the technical field of hardware stamping die technique and specifically relates to, it is a prevent that waste material stifled hole lower mould structure.
Background
In five metals stamping die, lower die structure includes the lower mould edge of a knife and lower mould, lower die structure has the waste material hole, the waste material hole is including the last perpendicular hole that link up the lower mould edge of a knife, the lower perpendicular hole of lower mould upper portion and last perpendicular hole intercommunication and the lower mould lower part and the decurrent inclined hole of discharge gate of lower perpendicular hole intercommunication, the perpendicular hole includes, accomplish when last stamping head and cut the back, the easy waste material card of irregular upset of waste material leads to the mould putty in the waste material hole, influence the continuity of production, can damage the mould even.
Thus, the prior art is subject to improvements and improvements.
SUMMERY OF THE UTILITY MODEL
For overcoming the weak point that exists among the prior art, the utility model aims at providing a prevent waste material stifled hole lower die structure that prevents of preventing waste material stifled hole, assurance production continuity and mould safety.
The utility model discloses a realize above-mentioned purpose through following technological means:
the utility model provides a prevent waste material stifled hole lower die structure, including the lower mould edge of a knife and lower mould, lower die structure has the waste material hole, the waste material hole is including the last vertical hole that link up the lower mould edge of a knife, the lower vertical hole of lower mould upper portion and last vertical hole intercommunication and the lower mould lower part and the decurrent inclined hole of discharge gate of lower vertical hole intercommunication, all be equipped with the mounting hole on the both sides wall of last vertical hole edge length direction of lower mould edge of a knife, install the slope stick in two mounting holes, the one side of discharge gate is kept away from in the last vertical hole that this slope stick is located the lower.
Preferably, the hole diameter of the upper part of the upper vertical hole matched with the upper die punch is smaller than that of the lower part.
Compared with the prior art, the beneficial effects of the utility model are that:
due to the adoption of the structural design, when the waste material drops, under the action of the inclined rod, one end of the waste material away from the discharge port is blocked by the inclined rod, so that the waste material close to one end of the discharge port is downward firstly, and then the waste material is inclined and discharged along the discharge port, so that the waste material is prevented from being clamped in a waste material hole due to irregular overturning of the waste material, and the production continuity and the die safety are ensured.
Drawings
FIG. 1 is a schematic sectional structure of the present invention;
fig. 2 is a schematic structural view of the lower die knife edge of the utility model.
The reference numbers in the figures are respectively: (1) the punching die comprises a lower die blade, (2) a lower die, (3) an upper vertical hole, (4) a lower vertical hole, (5) an inclined hole, (6) a mounting hole, (7) an inclined rod and (8) an upper die punching head.
Detailed Description
The invention will be described in further detail with reference to the accompanying drawings:
referring to fig. 1 and 2, the utility model relates to a lower die structure for preventing waste material from blocking holes, comprising a lower die knife edge 1 and a lower die 2, the lower die structure has a waste material hole, the waste material hole comprises an upper vertical hole 3 penetrating through the lower die knife edge 1, a lower vertical hole 4 communicating with the upper vertical hole at the upper part of the lower die, and a discharge hole downward inclined hole 5 communicating with the lower vertical hole 4 at the lower part of the lower die, two side walls of the upper vertical hole along the length direction of the lower die knife edge 2 are provided with mounting holes 6, two inclined rods 7 are mounted in the two mounting holes, the inclined rods are cylindrical, the inclined rods 7 are positioned at one side of the upper vertical hole of the lower die knife edge far from the discharge hole, by the structural design, when the upper die punch finishes cutting, the waste material drops under the action of the inclined rods, one end of the waste material far from the discharge hole is blocked by the inclined rods, so that the waste material near, the waste material that leads to is avoided irregularly overturning blocks in the waste material hole, guarantees the continuity of production and mould safety.
The aperture of the upper part of the upper vertical hole 3 matched with the upper die punch 8 is smaller than that of the lower part, so that waste materials can fall rapidly.
The utility model discloses simple structure thinks about ingeniously, can effectively solve the stifled hole problem of waste material that exists among the prior art, guarantees the continuity and the mould safety of production.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any person skilled in the art may use the above technical contents to change or modify the above embodiments into equivalent embodiments with equivalent changes.
Claims (2)
1. The utility model provides a prevent that waste material stifled hole lower die structure which characterized in that: including lower mould edge of a knife and lower mould, the lower die structure has the waste hole, the waste hole including the last vertical hole that link up the lower mould edge of a knife, the lower vertical hole of lower mould upper portion and last vertical hole intercommunication and the lower mould lower part with the decurrent inclined hole of discharge gate of lower vertical hole intercommunication, all be equipped with the mounting hole on the both sides wall of the last vertical hole edge length direction of lower mould edge of a knife, install the slope stick in two mounting holes, the one side of discharge gate is kept away from to the last vertical hole that this slope stick is located the lower mould edge of a knife.
2. The lower die structure for preventing the scrap from blocking the hole according to claim 1, wherein: the hole diameter of the upper part of the upper vertical hole matched with the upper die punch is smaller than that of the lower part.
