Description

Technical Field

[0001] The utility model relates to the technical field of carat tube production, in particular to a demoulding mechanism for carat tube production. Background Art

[0002] Carat tube is a hot-wound high-density polyethylene (HDPE) wound structural wall tube. This wall tube is made of high-density polyethylene resin as the main raw material, adopts a hot-wound process, and uses a polypropylene (PP) single-wall corrugated tube as a supporting structure to form a special structural wall pipe with high external pressure resistance. The carat tube includes a main body and a reinforcement tube wrapped around its outer side (some places also call it a PP corrugated tube or a wound tube). The reinforcement tube includes a core tube and an outer sleeve, and the outer sleeve is wrapped around the outer side of the core tube. Carat tubes are generally formed on cylindrical molds. After forming, the carat tube is still wrapped on the outer side of the mold, so it needs to be demolded. The following problems exist in the prior art:

During the pulling process, the carat tube is prone to displacement and sliding, thereby affecting the demoulding effect. Secondly, when the carat tube is demoulded, the unilateral pulling force slows down the demoulding efficiency and reduces the demoulding speed. Utility Model Content
