Metal hand model with spray painted surface and manufacturing method thereof

Abstract

The invention discloses a metal hand model with a spray painted surface and a manufacturing method thereof. The metal hand model comprises a hand model main body, wherein the hand model main body is formed by mutually pressing and welding a hand model left half body and a hand model right half body and performing CNC machining; and a welding surface of the hand model left half body and the hand model right half body is not in a middle-dividing position. According to the metal hand model with the spray painted surface and the manufacturing method thereof, the welding surface of the hand model left half body and the hand model right half body is not in the middle-dividing position, and the hand model left half body and the hand model right half body are both provided with protruding edges; the hand model left half body and the hand model right half body are welded through the protruding edges to form the hand model main body; and the protruding edges are cut off through the CNC machining, so that the metal hand model is formed. A design concept of vacancy compensation is adopted, and the protruding edges are arranged to serve as welding compensation process lines, so that excess metal protruding out of the compensation process lines is melted to compensate sunken grooves in the surface during laser welding of the metal hand model. Therefore, the situation that the grooves are formed in a weld seam of the hand model main body after welding is avoided, and the surface of the hand model is ensured to be smooth and uniform without sand holes after the weld seam is machined through CNC.

Description

technical field [0001] The invention relates to the technical field of metal hand molds, in particular to a metal hand mold with painted surface and a manufacturing method thereof. Background technique [0002] At present, in the production process of gloves such as latex, nitrile, PU or PVC, it is necessary to use hand molds for dipping and other processes. The quality of hand molds is directly related to the quality of gloves. [0003] Existing hand molds are mostly two kinds of ceramic hand molds and integral metal hand molds of gravity casting. Ceramic hand molds have the disadvantages of high energy consumption in the production process, fragile models, and at the same time, scrapped models have no recycling value and cannot be recycled, resulting in high production costs and environmental protection costs; gravity casting has poor surface smoothness and poor quality in the production process. The thickness of a single product is uneven, the same accuracy and repetitio...

Problems solved by technology

Ceramic hand molds have the disadvantages of high energy consumption in the production process, fragile models, and at the same time, scrapped models have no recycling value and cannot be recycled, resulting in high production costs and environmental protection costs; gravity casting has poor surface quality in the production process, The thickness of a single product is uneven, the same precision and repeat similarity between each product are extremely low, there are large differences, there are trachoma, many internal defects, low product qualification rate, low production efficiency, high labor intensity, The sand casting model used in the production process cannot be recycled and reused, which is likely to cause environmental pollution and high production costs.
