Novel lithium battery cover plate forming die

Abstract

The invention discloses a novel lithium battery cover plate forming die which comprises a base, four supporting rods are symmetrically and fixedly connected to the upper end of the base, a lower die is fixedly connected to the upper ends of the four supporting rods jointly, a U-shaped frame is fixedly connected to the upper end of the base, and a hydraulic oil cylinder is fixedly connected to the upper end of the U-shaped frame. The movable end of the hydraulic oil cylinder penetrates through the upper end of the U-shaped frame and is fixedly connected with an upper die, an ejection mechanism is installed on the base and comprises a driving box fixedly connected to the upper end of the base, a sliding plug is slidably connected to the inner wall of the driving box in a sealed mode, an ejection rod is fixedly connected to the upper end of the sliding plug, and a groove is formed in the bottom in the lower die. Compressed gas is injected into a high-pressure gas inlet pipe and converted through a vortex tube to generate hot gas, the hot gas enters the driving box to enable the sliding plug to move upwards, then a top plate is driven to move upwards, the formed lithium battery cover plate is ejected out of the lower die, the formed lithium battery cover plate is conveniently taken out, operation is easy and convenient, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of lithium battery cover plate processing, in particular to a novel lithium battery cover plate forming die. Background technique [0002] With the rapid development of the automobile industry, the demand for lithium batteries in the market is increasing, and lithium batteries need matching lithium battery cover plates in the production process, and most lithium battery cover plates are extruded through molding dies of. [0003] During the use of the existing new lithium battery cover forming mold, when the upper mold and the lower mold cooperate to extrude the lithium battery cover, the lithium battery cover may adhere to the lower mold, which is inconvenient to remove and must be removed manually It may cause deformation and damage to the formed lithium battery cover. In addition, the surface of the newly formed lithium battery cover will have a relatively high temperature, which may cause burns to worker...

[0003] During the use of the existing new lithium battery cover forming mold, when the upper mold and the lower mold cooperate to extrude the lithium battery cover, the lithium battery cover may adhere to the lower mold, which is inconvenient to remove and must be removed manually It may cause deformation and damage to the formed lithium battery cover. In addition, the surface of the newly formed lithium battery cover will have a relatively high temperature, which may cause burns to workers when handling it. At the same time, some raw materials will remain on the upper mold. These residual raw materials will affect the extrusion molding of the lithium battery cover plate
