Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1-5, the utility model relates to a punching mold for pressing battery packaging bag, which comprises an upper mold plate 100, a lower mold plate 200, a first pressing rod 110, a first pressing head 120, a first arc edge 121, a second arc edge 122, a third arc edge 123 and an anti-break angle 130.

The upper template 100 and the lower template 200, the upper template 100 is arranged above the lower template 200, the upper template 100 moves relative to the lower template 200, the first press rod 110 is arranged on the upper template 100, the first press head 120 is detachably connected to the first press rod 110, the lower template 200 is internally provided with a first press hole 210 corresponding to the first press head 120, when a packaging bag is pressed, people need to put the packaging bag horizontally on the lower template 200, in the process of punching the packaging bag by the pit punching die, the upper template 100 simultaneously drives the first press rod 110 to move, as the first press head is detachably connected to the end part of the first press rod 110, the first press head moves towards the first press hole 210, until the upper template 100 contacts with the lower template 200, the first press head 120 is completely inserted into the first press hole 210, so as to press a battery pit (not labeled in the figure) for installing a battery on the battery packaging bag, further, first pressure head 120 has four first arc limits 121, two second arc limits 122 and two third arc limits 123, be equipped with between adjacent first arc limit 121, second arc limit 122 and the third arc limit 123 and prevent brokenly angle 130, through should preventing brokenly angle 130, four first arc limits 121, two second arc limits 122 and two third arc limits 123's setting, reduce the sharpness that first pressure head 120 is close to the edge, especially reduce the sharpness of four angles of first pressure head 120, make this first pressure head 120 at the in-process of pressing the wrapping bag, this first pressure head 120 can not damage the wrapping bag, thereby guarantee that the wrapping bag can be used normally.

Further, because of first pressure head 120 is the detachable connection in first depression bar 110, make when first pressure head 120 is used for a long time by people, when the edge of first pressure head 120 appears damaged, people only need take off first pressure head 120 from first depression bar 110, the first pressure head 120 of renewal, alright reuse this towards hole mould, so, make things convenient for people to change, simultaneously, also avoid changing the condition of whole cope match-plate pattern 100.

At least two second pressure levers 140 are arranged on the upper template 100, each second pressure lever 140 is detachably connected with a second pressure head 150, a second pressure hole 220 corresponding to the second pressure head 150 is further formed in the lower template 200, when the upper template 100 moves towards the lower template 200, the upper template 100 drives the first pressure lever 110 to move synchronously, the second pressure heads are detachably connected to the end parts of the second pressure levers 140, the second pressure heads move towards the direction of the second pressure hole 220, and when the upper template 100 contacts with the lower template 200, the second pressure heads 150 are completely inserted into the second pressure holes 220, so that corresponding grooves (not labeled in the drawing) can be pressed on the battery packaging bag at the same time.

Further, because of second pressure head 150 is the detachable connection in second depression bar 140 for when second pressure head 150 used by people for a long time, when the edge of second pressure head 150 appeared damaged, people only need take off second pressure head 150 from second depression bar 140, the second pressure head 150 of renewal, alright reuse this towards hole mould, so, make things convenient for people to change, simultaneously, also avoid changing the condition of whole cope match-plate pattern 100.

Each anti-break corner 130 comprises first fillet 131, second fillet 132, third fillet 133, fourth fillet 134, fifth fillet 135 and sixth fillet 136, through the setting of first fillet 131, second fillet 132, third fillet 133, fourth fillet 134, fifth fillet 135 and sixth fillet 136, effectively reduces the sharpness at four angles of first pressure head 120 for this first pressure head 120 is at the in-process of suppression wrapping bag, and this first pressure head 120 can not damage the wrapping bag, thereby guarantees that the wrapping bag can be by normal use.

Further, a fourth fillet 134 and a fifth fillet 135 are connected to the first fillet 131, the fifth fillet 135 and a sixth fillet 136 are connected to the second fillet 132, the fourth fillet 134 and the sixth fillet 136 are connected to the third fillet 133, the fourth fillet 134 and the fifth fillet 135 are connected to the sixth fillet 136, and the fourth fillet 134 and the fifth fillet 135 are connected to the fifth fillet 135.
