The utility model provides a battery tab moulding piece mechanism, refer to fig. 1, battery tab moulding piece mechanism comprises after arranging side by side a plurality of moulding piece unit subassemblies, and moulding piece unit subassembly's briquetting casing is hard PC plastics material. The briquetting unit subassembly's briquetting casing divide into two parts, and the upper end part is the elastic layer, and the elastic layer is elastic material such as silica gel, and the tip is the plastic layer down, and the plastic layer uses materials such as hard PC plastics to make, and two parts realize the integration production through the mode of thermal injection molding. The lower end of the pressing block shell is provided with a supporting component, the supporting component is formed by manufacturing sheet metal parts, and the sheet metal parts and the bottom of the pressing block shell form an inner space. And the spring assembly is arranged in the inner space and is arranged at the bottom of the pressing block shell. After the spring assembly is installed, two ends of the spring assembly respectively abut against the bottom of the supporting assembly and the bottom of the pressing block shell, and are arranged in the inner space of the supporting assembly in a partially compressed state. Structural schematic diagram of rubber pressing block unit assembly with reference to fig. 2
