Supplementary pressure source device of mould debugging

The utility model discloses a supplementary pressure source device of mould debugging, including the backing plate, be equipped with the mounting hole on the backing plate, the upper portion of mounting hole is equipped with the U -shaped groove, and this U -shaped groove is linked together with the mounting hole, be equipped with the nitrogen gas jar in the mounting hole, nitrogen gas jar upper end is equipped with the flange, the U -shaped inslot is equipped with the trachea with nitrogen gas jar UNICOM. The utility model discloses utilizing the nitrogen gas jar pressure source in the backing plate, replacing lathe top shoe pressure source system, this device can use in the same field in the world, and easy and simple to handle, interchangeability is good, saves the cost, the high -usage. This device has compensatied all weak points of prior art, processes out the nitrogen gas jar mounting hole of gauged distance on the backing plate, installs the nitrogen gas jar in the mounting hole, utilizes the compression force of nitrogen gas jar, drives the pole mould pressure material core that reaches the higher authorities and normally works.
