The utility model relates to injection mold technical field, concretely to a battery shell is with injection mold of easy demoulding, include: base, the top surface fixed mounting of base has the mould box, the mould box inside slide installation has the sliding board, the one side slide installation of base has first threaded block, the top surface fixed mounting of first threaded block has the
fixed frame, first motor drives first
threaded rod to rotate, first threaded block will slide on the base, and then drive
fixed frame to move, make the mounting plate of
fixed frame one side and the injection molding device of bottom surface adjust to the proper position above the mould box, second motor drives second
bevel gear to rotate, because second
bevel gear and first
bevel gear are engaged, first bevel gear rotates along with and drive second
threaded rod to rotate, and the second threaded block of second
threaded rod outer wall screw installation will move up and down along the threaded rod, and the mounting plate fixed connection with second threaded block is just on the one side of fixed frame up and down slide, thereby the height of injection molding device is accurately adjusted.
