Vacuum cover assembly for polymer molding processing machinery

This creation is related to polymer molding processing technology, especially to a vacuum cover assembly for a polymer molding processing machine.

In the field of polymer molding processing technology, in order to prevent the residual air inside the mold from affecting the polymer material inside the mold at a high temperature, it is necessary to ensure the mold chamber when pouring and injecting the polymer material into the mold cavity space of the mold. The air in the space is properly extracted, and in order to achieve the project, in the conventional technology, after the mold is closed and the complete cavity space is formed, the cavity is preset in the cavity by the air vent on the die. The air is pumped away, and the mold is placed in a vacuum environment, so that there is no air left in the mold clamping, so that there is no residual air in the formed cavity, which is a technique in the field of polymer molding processing. It is already a common technical content.

Among them, in the conventional vacuum pumping technology in which the mold is placed in a vacuum environment, the specific example is as disclosed in the new patent No. M316793 of the prior art, which is to isolate the outside atmosphere by the cover body to form an independent space.
