[0002] Extrusion molding is mostly used in the forming process of telescopic tubes. The existing molding molds are generally complex in structure and require high equipment operation accuracy, and are only suitable for the production of plastic telescopic tubes, not suitable for the production of paper, fiber, or woven Telescopic tubes made of cloth and other materials
The production of telescopic tubes made of paper, fiber, or woven fabrics needs to be produced through a stamping process, and the integrated stamping mold may cause local holes or frills in the telescopic tube during the molding process, which requires further processing, increasing production process
In addition, it is also possible to punch out several arc-shaped telescopic units by means of step-by-step molding, and then overlap the edges of the several arc-shaped telescopic units to form a telescopic tube. Manual work is completed, the production efficiency is low, and it cannot meet the needs of mass production, and the sides of the overlapping are uneven and the quality is poor

The invention provides an extension tube splicing die. The extension tube splicing die comprises a plurality of inner sliders arranged at intervals and a plurality of outer sliders arranged on the outer sides of the interval parts of the inner sliders, wherein the outer sides of the inner sliders and the inner sides of the outer sliders are connected end to end to form a circumference; the inner sliders and the outer sliders can slide relative to each other; a first corrugated groove is formed in the outer side of each inner slider and is corrugated in longitudinal cross section and arc-shaped in transverse cross section; a second corrugated groove is formed in the inner side of each outer slider and matched with the first corrugated grooves in shape; and the two end edges of the outer side of each inner slider can cling to the edges of the inner sides of the outer sliders adjacent to the inner slider. The extension tube splicing die is simple and easy to operate, can automatically control splicingto be completed, improves the production efficiency, and is uniform in splicing force, and the spliced extension tube is good in quality.
