Description

Technical Field

[0001] The utility model specifically relates to a high-stability fixed-position locking hand mold base, belonging to the technical field of hand mold bases. Background Art

[0002] The hand mold base is an important component in the production line of disposable gloves (latex gloves, nitrile gloves, PVP gloves, household gloves) for installing glove molds. However, the existing hand mold bases are not convenient for positioning and locking the hand molds, resulting in displacement deviation and detachment easily occurring when the hand mold bases rotate at high speed, affecting glove production. Moreover, when fixing the hand molds, it is necessary to hold the hand molds by hand all the time, which is not convenient for fixing the hand molds.

[0003] For example, the publication number: CN208133442U, a hand mold base, has a structure where one end of the shaft rod is a prism section, a core sleeve that matches the shape of the prism section of the shaft rod and is sleeved is provided on the connecting seat, a hand mold clamping member is connected to the end of the shaft rod extending out of the core sleeve, the other end of the shaft rod is connected with a chain hanging member through a bearing, a self-locking nut is screwed on the end of the shaft rod extending out of the chain hanging member, and a spring is sleeved on the shaft rod between the chain hanging member and the connecting seat, and the spring abuts the hand mold clamping member against the disk surface of the connecting seat. The utility model has simple processing, long service life, and good operation stability. The shaft rod has high strength and is not easily bent and deformed. There is basically no relative movement between the shaft rod and the connecting seat, avoiding the hand mold deflection caused by shaft rod wear and ensuring the production quality of gloves. Summary of the Utility Model
