The utility model relates to a fused socket type pipe socket mould, including core mold, mold guide sleeve, outer mold and outer mold sleeve is arranged on the inner side of the outer mold material retaining ring, core mold guide sleeve through the connecting bolt and the mandrel are connected as a whole, the core mold, mold guide sleeve and the outer mould and the outer mould material retaining ring and the winding pipe to form a shape of the mold cavity socket. The outer mould is divided into symmetrical upper and lower two parts, and the outer mould is provided with at least one injection port, and the injection mold is communicated with the mold cavity. The core mould is also provided with a straight line slot, and two heating lead wires can be placed. A heating net is coated on the core mould, and the heating net is connected with the heating extraction line. The utility model has the advantages of simple structure and high efficiency, injection will be electric welding mesh is embedded in socket wall, will not fall off, can be stored for a long time, compared with the traditional manual offline net safer, more convenient, and compared with the traditional independent type of welded joint, without re welding, to avoid leakage problems such as welding. Manual welding.
【技术实现步骤摘要】
一种电熔承插式缠绕管承口模具
本技术涉及一种缠绕管接头生产模具,具体涉及一种电熔承插式缠绕管承口模具。
技术介绍
聚乙烯结构壁缠绕管具有耐腐性、磨擦阻力低、抗磨损等优点,具有很高的环刚度,埋地深,而且整体成型工艺好,缝拉伸强度及防腐性高,寿命更长;具有多种可靠,方便的连接方式。这种管材目前已经成为当前塑料排水排污管材的投资热点。这类复合管的连接中,接头管件及其与管材的连接结构至关重要。目前,聚乙烯结构壁缠绕管有A型管和B型管。对于A型管通常使用的收缩带或收缩套或焊丝热熔焊接承插等连接方式存在非常大安全隐患,通常也很难保证闭水试验通过;而B型管目前有有两种生产工艺,一种采用间歇式滚筒生产,该方式使用整体成型接头,成型后经车制成要求的接头尺寸,然后再通过人工将S型铜丝使用铆钉枪固定在承口内壁,操作工序较多,且由于铆钉容易生锈导致铜丝脱落,B型管另外一种连续生产方式有第一种接头生产方式,也有A型管连接方式。按照目前方式,无论哪一种方式都存在有一些缺陷。国内缠绕波纹管和中空壁缠绕管的生产设备已经非常成熟,但都具备单一性且只能生产管材母体,承插式连接的承插口需要二次加工成型 ...
