Description

A kind of stamping mold water material cut-out Anti-blockage mechanism

Technical field

The utility model is related to diels, and in particular to a kind of stamping mold water material cut-out Anti-blockage mechanism.

Background technology

When carrying out the trimming of auto parts and components local shape complexity, it often will appear waste material and hang over part indentation, there, or It is that waste material is interfered with mould structure, causes waste material to exclude difficult.There are mainly two types of the schemes for currently solving the problems, such as this：It is a kind of It is the landing direction by adding the modes such as bullet ejector pin, guide rod to control waste material, waste material is made to be slid by preset path, but due to setting The meter stage is difficult that landing direction to waste material and path are accurately simulated, and can only carry out control by rule of thumb, lead to the row in later stage Expect very risky, in addition, playing ejector pin belongs to vulnerable part, when volume production, failure, which is replaced, influences production efficiency.Another kind is in technique side By complicated waste material piecemeal when case designs, cut by two-step substep on mold；Although complicated waste material is carried out substep Cutting can effectively reduce the risk that gets stuck, but the mode of operation break-down cutting increases the layout difficulty of process program, may with it is rear The functions such as shaping, the flange in face clash, or even can increase number of molds, increase manufacturing cost.

Invention content

The purpose of this utility model is to provide a kind of stamping mold water material cut-out Anti-blockage mechanism, can be in the same process It is interior to cut waste material piecemeal and disposably, evade the risk that gets stuck.

Stamping mold water material described in the utility model cut-out Anti-blockage mechanism, including upper die holder and lower die holder, it is described on Die holder is equipped with upper mold trimming cutter block, and the upper mold trimming cutter block is made of multiple trimming inserts, the boundary of multiple trimming inserts Boundary line between line and waste material piecemeal is corresponding, and the lower die holder is equipped with lower die, and the lower die is equipped with lower die trimming cutting edge, Lower die trimming cutting edge is matched with the periphery of upper mold trimming cutter block, and trimming integer is carried out to product.

Further, the quantity of the trimming insert is two, including the first trimming insert being disposed adjacent and the second trimming Insert.

Further, the position of the first trimming insert is higher than the second trimming insert.

Further, the upper mold trimming cutter block is fixedly connected by trip bolt with upper die holder.

Further, further include eccentric swage, the eccentric swage is slidably mounted on upper die holder.

Further, the lower die is equipped with waste sliding plate.

The utility model has the beneficial effects that：By the way that multiple trimming inserts, and the line of demarcation of multiple trimming inserts is arranged Boundary line between waste material piecemeal is corresponding, and the waste material of labyrinth is divided into relatively simple a few parts, solves waste material It is easy to be stuck on part and the problem of discharge difficulty.And the piecemeal cutting to waste material is realized in the same process, is avoided It is clashed with product subsequent treatment process, reduces the layout difficulty of process program, reduce manufacturing cost.

Specific implementation mode

It elaborates below in conjunction with the accompanying drawings to the utility model.

Referring to Fig. 1 to Fig. 5, shown in stamping mold water material cut-out Anti-blockage mechanism, including upper die holder 1 and lower die holder 2, institute It states and is slidably fitted with eccentric swage 3 on upper die holder 1, upper mold trimming cutter block 4, the upper mold edge-trimming cutter are fixed with by trip bolt 8 Block 4 is made of two trimming inserts, including the first trimming insert 41 and the second trimming insert 42, the first trimming insert 41 Position is higher than the second trimming insert 42, difference in height 4mm.The line of demarcation of first trimming insert 41 and the second trimming insert 42 with it is useless Expect that the boundary line 12 between piecemeal is corresponding, the lower die holder 2 is equipped with lower die 7 and waste sliding plate 6, and the lower die 7 is equipped with down It is die cut side cutting edge 5, lower die trimming cutting edge 5 is matched with the periphery of upper mold trimming cutter block 4, and trimming integer is carried out to product 9.

When specific works, product 9 is positioned on 7 type face of lower die, 9 edge waste of product divides into garbage area I 10 and gives up Expect area II 11.Start diel, eccentric swage 3 and upper mold trimming cutter block 4 move downwardly together with upper die holder 1, run to certain Eccentric swage 3 is contacted with product 9 when height, provides pressure-plate-force, and eccentric swage 3 goes downwards to minimum point at this time.Upper mold trimming cutter block 4 with Upper die holder 1 continues to move downward, and the first trimming insert 41 is contacted with product 9, will under the mating reaction of lower die trimming cutting edge 5 Garbage area I 10, which is cut, to be fallen, and upper die holder 1 continues to move downward, and the second trimming insert 42 is contacted with product 9, in lower die trimming cutting edge 5 Under mating reaction, garbage area II 11 is cut and is fallen, upper die holder 1 runs to minimum point with upper mold trimming cutter block 4 at this time, cuts the waste material fallen Mold is skidded off along waste sliding plate 6.In return stroke, upper die holder 1 and upper mold trimming cutter block 4 move upwards first, then drive Eccentric swage 3 moves upwardly together, and returns to initial position.
