| description | The invention relates to an integrated ultra-large mold vacuumizing structure, and belongs to the technical field of vacuumizing structures. By arranging a sealing ring, in the process that a movable mold slides towards a fixed mold, the sealing ring is firstly in sealing fit with a groove hole, and a sealed space is formed before the movable mold and the fixed mold are not in sealing fit with each other; the vacuum pump is communicated with the sealed space, so that gas in the sealed space is extracted in advance, and after the movable die and the fixed die are connected with each other in a sealed mode, vacuum extraction is completed in the die-casting space between the movable die and the fixed die, and the problems that an existing ultra-large die is large in die-casting space, and after the movable die and the fixed die of the ultra-large die are connected with each other in a sealed mode, vacuum extraction is completed are solved. And the time required for vacuumizing treatment in the die-casting die is |
