This utility model belongs to the field of battery manufacturing technology and discloses a punching mold for aluminum-plastic film of soft-pack batteries. The punching mold for aluminum-plastic film of soft-pack batteries includes a concave mold, a guide mold, at least one first punch, and at least one second punch. The concave mold has at least one first groove and at least one second groove, with the second groove located on either side of the first groove. The guide mold is disposed on the concave mold, and the aluminum-plastic film to be formed is sandwiched between the guide mold and the concave mold. The first punch includes at least one first protrusion, which can pass through the guide mold and move towards the first groove to punch and form the receiving cavity. The second punch includes at least one second protrusion, which is located on either side of the first punch. The second protrusion passes through the guide mold and moves towards the second groove to punch and form the receiving space, thereby enabling the manufacture of aluminum-plastic film that improves the support strength, liquid retention, and / or safety of soft-pack batteries.
