AI Technical Summary
Existing aluminum-plastic film stamping dies suffer from wear due to contact between the die core and the template during the stamping process, affecting stamping accuracy and consistency, resulting in a high defect rate and increased production costs.
Reinforcing ribs are set on the surface of the upper template to prevent the mold core from directly contacting the upper template. By setting reinforcing ribs on the surface of the upper template corresponding to the position of the mold core, the mold core is prevented from directly contacting the upper template, so as not to affect the subsequent stamping accuracy and to ensure the yield of lithium batteries in the stamping process.
By adding reinforcing ribs to protect the mold, stamping accuracy and consistency are improved, the defect rate is reduced, and production costs are lowered.
