There is the first ramp；The position that the lower die corresponds on the outside of the lateral incision formed punch is provided with feed opening, described in the upper mold is corresponding
The position of feed opening is provided with waste material mandril；During the lower slotting tool and waste material mandril move down, first lower inclined plane is squeezed
It presses the first ramp and makes the sliding block to the movement of the lateral direction of the mold core, and on first lower inclined plane and first
After inclined-plane is detached from, the waste material mandril is inserted into the feed opening.
As an improvement of the above technical solution, position of the upper mold on the outside of the upper cavity is provided with compacting machine
Structure.
Further, the hold-down mechanism includes upper slotting tool and the top shoe being arranged in upper mold, and the top shoe is close
The upper cavity, the lower end of the upper slotting tool are provided with the second lower inclined plane, and the top shoe is provided with the second ramp；On described
When slotting tool moves down, second lower inclined plane squeezes second ramp and the top shoe is made to break away to the upper cavity one
It is dynamic.
Further, the hold-down mechanism has multiple and symmetric around around the upper cavity.
Further, the top shoe and sliding block are provided with elastic reset structure.
Further, the elastic reset structure is specially compressed spring.
The utility model has the beneficial effects that：The utility model can either carry out lateral incision to product from side, avoid product
Side occur has flange trace, highly has the problem of error, guarantees that the height dimension of product reaches standard requirements；Meanwhile and energy
The waste material generated after lateral incision is enough removed by waste material mandril and feed opening, avoids the table of waste material scratching products in subsequent handling
Face is further ensured that the quality and overall aesthetics of product, to improve the competitiveness and customer satisfaction of product.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the high view structural schematic diagram of upper mold described in the utility model；
Fig. 2 is the overlooking structure diagram of lower die described in the utility model；
Fig. 3 is the integral assembling structure schematic diagram of the utility model.
Specific embodiment
Referring to figs. 1 to 3, a kind of ear cap punching press side-cutting die of the utility model includes upper mold 1 and lower die 2, described
Upper mold 1 is provided with upper cavity 11 and lower slotting tool 12, and the lower die 2 is provided with mold core 21 and sliding block 22, the mold core 21 and upper
The position of shape forming cavity between die cavity 11, corresponding 21 lower edge of mold core of the sliding block 22 is equipped with lateral incision formed punch 221, institute
The lower end for stating lower slotting tool 12 is provided with the first lower inclined plane, and the sliding block 22 is provided with the first ramp；The corresponding institute of the lower die 2
The position for stating 221 outside of lateral incision formed punch is provided with feed opening 23, and the position of the corresponding feed opening 23 of the upper mold 1 is provided with useless
Expect mandril 13；During the lower slotting tool 12 and waste material mandril 13 move down, first lower inclined plane squeeze the first ramp and
Keep the sliding block 22 mobile to the lateral direction of the mold core 21, and is detached from first lower inclined plane and the first ramp
Afterwards, the waste material mandril 13 is inserted into the feed opening 23.The working principle of the utility model is：Firstly, by profile height
It has been completely stretched in place and has passed through web feed device etc. there are the semi-finished product ear cap product of enough trimming allowances and be delivered to
At side-cutting die described in the utility model, and pass through the material strip with semi-finished product ear cap between upper mold 1 and lower die 2；
When carrying out lateral incision processing to semi-finished product ear cap, 1 downlink of upper mold and lower die 2 are molded, and ear cap is pressed onto the mold core 21 of lower die 2
On, while it is intracavitary so that ear cap is entered type；Then upper mold 1 continues traveling downwardly, and lower slotting tool 12 is started to work so that 22 band of sliding block
Dynamic lateral incision formed punch 221 realizes lateral trimming to the outside of mold core 21 is mobile；Then upper mold 1 continues traveling downwardly, and waste material mandril 13 will be cut
The waste material that side generates is ejected through feed opening 23；Then 2 uplink of upper mold and complete reply movement, to carry out the punching press of next circulation
Operation.Therefore, the utility model can either carry out lateral incision to product from side, and avoiding product from side occur has flange trace, height
Degree has the problem of error, guarantees that the height dimension of product reaches standard requirements；Meanwhile and waste material mandril 13 and blanking can be passed through
Mouth 23 removes the waste material generated after lateral incisions, avoids the surface of waste material scratching products in subsequent handling, is further ensured that product
Quality and overall aesthetics.
In the present embodiment, effectively fixed in order to be carried out before lateral incision operation to product, avoid product in lateral incision
Play is generated in journey and influences machining accuracy, and the upper mold 1 is provided with hold-down mechanism close to the position in 11 outside of upper cavity.
Specifically, the hold-down mechanism includes the upper slotting tool 14 and top shoe 15 being arranged in upper mold 1, and the top shoe 15 is close to institute
Upper cavity 11 is stated, the lower end of the upper slotting tool 14 is provided with the second lower inclined plane, and the top shoe 15 is provided with the second ramp；Institute
When stating slotting tool 14 and moving down, second lower inclined plane squeezes second ramp and makes the top shoe 15 to the upper cavity
11 1 Slideslips, to be fixed ear cap by the sliding block 22 and the cooperation of upper cavity 11 or mold core 21.Also, in order to
Make being more uniformly stressed for ear cap product in compaction process, the hold-down mechanism has multiple and symmetric around described
Around upper cavity 11.
In the present embodiment, in order to enable top shoe 15 and sliding block 22 can automatically revert to just after 2 uplink of upper mold
On the position of beginning, specifically, the top shoe 15 and sliding block 22 are provided with elastic reset structure 3.And, it is preferable that institute
Stating elastic reset structure 3 is specially compressed spring；Certainly it can also be used other than using compressed spring according to the actual situation
The other kinds of elastic reset structure 3 such as extension spring.
The above is the preferred embodiment of the utility model, but the utility model is not limited to above-described embodiment, only
It wants it to reach the technical effect of the utility model with any same or similar means, should all fall into the protection scope of the utility model
Within.
