Low-pressure forming die for earphone battery

Abstract

The utility model discloses an earphone battery low-pressure forming die which comprises an upper die, a lower die and a die strip, an installation groove is reserved between the upper die and the lower die, the die strip is provided with a limiting groove used for limiting a circuit board and a cavity used for placing a battery cell, the peripheral wall of the limiting groove is attached to the peripheral wall of the circuit board, and the peripheral wall of the middle section of the battery cell is attached to the inner wall of the cavity. Gaps are reserved between the two ends of the battery cell and the cavity to form injection molding grooves, runner grooves used for installing injection molding runners are reserved in the top walls of the mold strips, the runner grooves are communicated with the injection molding grooves, and when the circuit board is installed in the limiting groove, the circuit board separates the injection molding groove close to the negative electrode of the battery cell from the limiting groove; the cavity is provided with a connecting groove, the connecting groove is communicated with the injection molding grooves in the two ends, the periphery of the battery cell is provided with a connecting piece for pulling the positive electrode to the negative electrode, and the connecting groove directly faces the connecting piece. According to the utility model, the battery cover can be assembled and reinforced during injection molding, so that the assembly process can be simplified, and the cell processing efficiency can be improved.
