Manufacturing method of metal hand mold

Abstract

The invention discloses a manufacturing method of a metal hand mold. The manufacturing method comprises the following steps: (1) punching and forming a metal plate into a left palm blank and a right palm blank by using a punching machine, heating the left palm blank and the right palm blank, then forging the left palm blank and the right palm blank through a forging machine, trimming and shaping the left palm blank and the right palm blank, deburring and cleaning; (2) carrying out special-shaped pipe manufacturing on a metal pipe through a pipe flaring and necking machine and a corresponding mold, and then manufacturing an arm blank through cutting; (3) heating the metal plate, forging and forming a base buckle blank by using the forging machine, trimming the base buckle blank, deburring and cleaning; and (4) fixedly assembling the left palm blank, the right palm blank, the arm blank and the base blank, and performing laser welding by using a laser welding machine to form a hand mold main body. The process is simple, and the produced product has the advantages of high strength, durability, energy conservation and the like, and is high in practicability.

Description

technical field [0001] The invention relates to the technical field of hand molds, in particular to a method for making a metal hand mold. Background technique [0002] 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 integral metal hand molds of ceramic hand molds and 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 repetition similarity between each product are extremely low, t...

AI Technical Summary

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 smoothness and poor 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 trachoma, many internal defects, low product qualification rate, low production efficiency and other defects

[0004] In the prior art, there are also some methods of making metal hand molds, but these methods generally have certain shortcomings, such as the relatively complicated process and the disadvantages of insufficient strength and durability of the hand molds produced.
