Problems solved by technology

As a result, the requirements for the profile structure of the battery frame are becoming more and more complex, and the multi-reinforced and multi-cavity profile structure is increasingly applied to the frame section of the battery tray. This type of section is difficult to extrude and the mold life is low.

Abstract

The invention discloses a multi-work-head battery frame extrusion die. The extrusion die comprises an upper die and a lower die, eight groups of diversion holes are formed in the periphery of the bottom end of the feeding surface of the upper die, a bridge position is arranged between every two groups of diversion holes, a middle rib back hole is formed in the middle of the bottom end of the feeding surface and in the middle of each group of diversion holes, a plurality of groups of work heads are arranged at the bottom end of the middle rib back hole, and an inclined protection structure is arranged at the position, close to one group of work heads, of each group of diversion holes. The extrusion die has the beneficial effects that the cross section extrusion forming difficulty of a battery tray frame with the multi-rib multi-cavity profile structure during production can be reduced, and the service life of the die is prolonged, so that the die has good strength and formability.

Description

technical field [0001] The invention relates to the technical field of extrusion dies, in particular to a multi-head battery frame extrusion die. Background technique [0002] A mold is a tool for obtaining profiles by forming materials. It mainly changes the physical state of the materials and passes the materials into the mold to realize the processing of the profiles, so as to obtain the required profiles. [0003] With the promotion and use of new energy vehicles, most of the current mainstream electric vehicles use lithium battery power to start, which puts forward new requirements for the use of lithium battery carrying trays on vehicles. The battery tray not only needs to support the power battery pack but also needs to be To act as a car safety parts. As a result, the requirements for the profile structure of the battery frame are becoming more and more complex, and the multi-rib and multi-cavity profile structure is more and more applied to the frame section of the...
