The glove mold is a mold used as a glove dipping aid in a dipping glove factory, and is mainly divided into a ceramic glove mold and a metal glove mold at present. The metal glove mold is suitable for the processing fields of various PU, PVC, butyronitrile, latex, films and other gloves. Because the metal glove mold has higher structural strength and better temperature-raising heat-dissipating performance than the ceramic glove mold, the metal glove mold is more common in practical application.

The metal glove mold is generally manufactured by a casting process, and a blank of the hand mold is obtained after molten metal is introduced into the mold and cooled. The existing hand mold blank generally comprises a left half body of the hand mold, a right half body of the hand mold (the left half body and the right half body of the hand mold are not corresponding to the left hand and the right hand, but mean two basically symmetrical components forming the hand mold, and both comprise an arm, a palm and a finger part) and a base. The two hand mold half bodies of the hand mold blank have redundant metal at the finger tips and the wrist positions of the fingers, and the fingers are generally connected with each other, so that the redundant metal of the hand mold blank needs to be cut to obtain a final hand mold finished product.
