The produced pipe of current plastic pipe mostly is straight tube, and pipe ends is not with connecting head, and when constructing, scene makes joint temporarily, make trouble, efficiency is low, installs also inconvenient, and pipeline junction sealing is poor, during heat affecting length change of catching a cold, the performance of pipeline can not ensure.
Summary of the invention
The object of this invention is to provide a kind of plastic pipeline joint, can directly connect, avoided making joint at the construction field (site), inefficient problem temporarily, and can effectively ensure pipeline catch a cold heat affecting length change time sealability, cost is low.
Another object of the present invention there is provided the process units of plastic pipeline joint.
The technical solution used in the present invention is as follows:
A kind of plastic pipeline joint, comprise inner pipe joint, outer tube joint and seal ring, described inner pipe joint is injection-moulded in interior pipe one end by injection mould, and described outer tube joint is injection-moulded in outer tube one end by injection mould, and described seal ring is arranged in the middle of inner pipe joint and outer tube joint.
Described inner pipe joint and outer tube joint injection molded by high-density polyethylene material.Improve anticorrosion, wear-resisting, resistance to compression, sealability.
The process units of described plastic pipeline joint, comprise injection moulding tube head, support, upper cylinder, upper die and lower die, lower oil cylinder, rear oil cylinder, rear core and plumber's part position shelf, described upper cylinder connects patrix, lower oil cylinder connects counterdie, core after rear oil cylinder connects, form die cavity after the combination of described upper die and lower die, rear core, described upper cylinder, upper die and lower die, lower oil cylinder, rear core and rear oil cylinder are all arranged on support, and described support front arranges plumber's part position shelf.
When plastic pipeline joint of the present invention is produced, after first starting, oil cylinder puts in place, and core after being inserted by duct work is also fixed on plumber's part position shelf, then starts upper and lower oil cylinder, and with rear core matched moulds, connecting injection moulding tube head can start molding and forming; After injection moulding terminates, first exit rear core, then move back upper and lower mould, then remove duct work and get final product complete operation.
Compared with the prior art, beneficial effect of the present invention is as follows:
(1) plastic pipe joint of the present invention, by injection mould at inner and outer tubes one end difference injection moulding inner pipe joint and outer tube joint, at the construction field (site), inner pipe joint is inserted outer tube joint, easily effectively can realize the connection of pipeline, improve efficiency of construction, and each structure be relatively independent, be easy to repair after pipeline breaks down and change, easy to operate;
(2) inner pipe joint of the present invention and outer tube joint injection molded by high-density polyethylene material, there is anticorrosion, wear-resisting, resistance to compression, sealing, the function such as reliable and stable; In the middle of inner pipe joint and outer tube joint, seal ring is set, can effectively ensure pipeline catch a cold heat affecting length change time sealability;
(3) process units of plastic pipeline joint of the present invention, during production for plastic pipeline joint, efficiency is high, structure is simple, and cost is low, easy-to-operate, plumber's part position shelf is set in support front, for fixed tube workpiece during injection moulding, improve the stability of device, improve injection moulding effect.
