Description

Technical Field

[0001] The present application belongs to the field of hand mold installation, and relates to a hand mold installation device for glove production. Background Art

[0002] Gloves are made of polyvinyl chloride as the main raw material. The main raw materials used are PVC paste resin, plasticizer, viscosity reducer, heat stabilizer, colorant and filler. The gloves made have good anti-static properties and are suitable for use in various industries such as semiconductor processing, food processing, and vending.

[0003] Hand models are needed to assist in the production of gloves. Figure 1 , Figure 2 As shown, a long strip-shaped mounting hole is provided at the bottom of the hand mold, and a long strip-shaped positioning groove is provided on the hole wall of the mounting hole, and the positioning groove is perpendicular to the mounting hole.

[0004] The hand mold used in glove production is used on the glove production line. First, it needs to be installed on a fixture, and then installed on the glove production line together with the fixture to move with the line.

[0005] like Figure 3 , Figure 4 As shown, the clamp includes a mounting seat, a pressure rod is arranged on the mounting seat, a positioning portion matching the mounting hole at the bottom of the hand mold is arranged at the upper end of the pressure rod, a spring is also arranged on the mounting seat, a tray is arranged at the upper end of the spring, and the upper end of the pressure rod passes through the tray. When installing the hand mold, it is necessary to press the tray with both hands, and then align the mounting hole at the bottom of the hand mold with the positioning portion of the pressure rod, so that the positioning portion passes through the mounting hole, and at the same time, the hand mold is rotated 90° so that the positioning portion is rotated into the positioning groove to form a snap connection with the positioning groove.
