technical field

The invention relates to the technical field of molds, in particular to a folding mold for a long leg tube of a swivel chair.

Background technique

Chairs are a common piece of furniture in daily life. With the continuous improvement of technology, more and more types of chairs have emerged. Swivel chairs are one of them. In order to keep the structure simple, the base of swivel chairs often only contains trays, Column, leg tube, runner and other structures, among which leg tube includes long leg tube and short leg tube. In the production process of long leg tube, hemming is an important process. This process is mainly completed by folding die. In the process of edge folding, the side mold often simply presses and preliminarily forms the raw material plate of the long leg tube through the clamping of the upper mold and the lower mold. The quality of the finished product is not high, and the subsequent cooperation with the runner and the short leg tube is also affected to a certain extent. Based on this situation, how can the molding process of the long leg tube be more accurate so that the quality of the finished product of the long leg tube can be effectively improved? It has become an urgent problem for relevant technicians to solve.
