Description

TECHNICAL FIELD

[0002] In the prior art, palm-shaped bionic molds are usually used in the production process of latex, nitrile, PU or PVC gloves to perform processes such as glove product dipping and shaping, wherein the quality of the palm-shaped bionic mold directly affects the quality of the corresponding glove product. At present, the palm-shaped bionic mold is mainly prepared by pressure casting process to obtain a palm-shaped embryo, and then the palm-shaped embryo is prepared by welding processes such as friction stir welding, argon arc welding, laser welding, two-protective welding or brazing. However, the palm-shaped bionic mold prepared by the process has defects such as many pores, color difference and a large amount of oxide impurities. Based on this, the inventors found that the use of rotary friction welding to prepare the palm-shaped bionic mold can improve the defects such as many pores, color difference and a large amount of oxide impurities of the palm-shaped bionic mold. However, since the wrist opening of the palm-shaped embryo after pressure casting in the traditional preparation process is usually elliptical, and the rotary friction welding requires the wrist opening of the palm-shaped embryo to be a right circular shape, there is currently no related mold for shaping the opening at the wrist of the palm-shaped embryo into a right circular shape.

[0053] It should be noted that since the material of the palm-shaped embryo part is usually aluminum alloy, in order to more effectively assist shaping, the shaping device can also be provided with a heating function, so that the palm-shaped embryo part can be extruded and shaped after being softened.

[0054] Referring to Figure 2 As an example, the lower die 200 is provided with a plurality of first heating channels 230 spaced circumferentially along the first through groove 210, and the upper die 300 is provided with a plurality of second heating channels 330 spaced circumferentially along the second through groove 310.

By arranging the heating channels, the wrist opening of the palm-shaped embryo part can be softened by high temperature before being shaped by the shaping unit 500, so that the elliptical wrist opening can be more easily and effectively shaped into a perfect circle.
