Description

Technical Field

[0001] The present invention relates to the technical field of hand molds, and in particular to a hand mold. Background Art

[0002] Glove molds are a type of mold used by glove factories to assist in glove dipping. Currently, glove molds are mainly divided into ceramic glove molds and metal glove molds. Metal glove molds are suitable for various PU, PVC, nitrile, latex, film and other glove processing fields. Because metal glove molds have higher structural strength and better temperature and heat dissipation performance than ceramic glove molds, they are more common in actual applications.

[0003] Metal molds are generally manufactured through a casting process. After the molten metal is introduced into the mold, the blank of the hand mold is obtained after cooling. Existing hand mold blanks generally include a left half of the hand mold, a right half of the hand mold (the left half of the hand mold and the right half of the hand mold do not correspond to the left and right hands, but refer to the two basic symmetrical components that constitute the hand mold, both including the arm, palm and finger parts) and a base. The two halves of the hand mold blank have excess metal at the fingertips and wrists of the fingers. At the same time, there are generally bridges connecting the fingers to each other. The excess metal of the hand mold blank needs to be cut to obtain the final hand mold product. Due to the complexity of the hand mold structure, the cutting process is time-consuming and labor-intensive, and the efficiency is low, which increases the production cost of the hand mold blank, and thus a device for punching the hand mold blank has emerged.

[0004] During the welding process of the two hand model halves, the part between the fingers is difficult to weld and the weld seam is difficult to process, which leads to a long welding time between the two hand model halves, high production costs, and also affects the quality of the metal hand model product. Therefore, the applicant has developed a new type of metal hand model consisting of a hand blank (fingers and part of the palm) and an arm blank (arm and part of the palm). The production and manufacturing only needs to weld the left half arm blank and the right half arm blank, without welding the hand blank with a more complex structure, which greatly improves the production efficiency and product quality of the hand model.
