Plastic pipeline connector and production device for plastic pipeline connector

Abstract

The invention discloses a plastic pipeline connector and a production device for the plastic pipeline connector. The plastic pipeline connector comprises an inner pipe joint, an outer pipe joint and a seal ring; the inner pipe joint is subjected to injection molding at one end of an inner pipe by an injection mold; the outer pipe joint is subjected to injection molding at one end of an outer pipe by the injection mold; the seal ring is arranged between the inner pipe joint and the outer pipe joint; the production device comprises an injection molding pipe head, a support, an upper oil cylinder, an upper die, a lower die, a lower oil cylinder, a back oil cylinder, a back mandrel and a pipe workpiece positioning frame; the upper oil cylinder is connected with the upper die; the lower oil cylinder is connected with the lower die; the back oil cylinder is connected with the back mandrel; the upper die, the lower die and the back mandrel are combined to form a die cavity; the upper oil cylinder, the upper die, the lower die, the lower oil cylinder, the back mandrel and the back oil cylinder are arranged on the support; the pipe workpiece positioning frame is arranged in front of the support. According to the plastic pipeline connector, one end of the inner pipe and one end of the outer pipe are respectively provided with the inner pipe joint and the outer pipe joint through injection molding, the inner pipe joint is inserted into the outer pipe joint at the construction field, and the pipeline connection is easy to realize; the production device for the plastic pipeline connector is simple in structure, low in cost and safe and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to a plastic pipe connector and a production device thereof. Background technique [0002] At present, most of the pipes made of plastic pipes are straight pipes, and there are no joints at both ends of the pipes. Temporary joints are made on site during construction, which is troublesome to make, low in efficiency, and inconvenient to install. Moreover, the sealing of the joints of the pipes is poor and affected by cold and heat. The performance of the pipe as the length changes is not guaranteed. Contents of the invention [0003] The purpose of the present invention is to provide a plastic pipe joint, which can be directly connected, avoiding the problem of low efficiency caused by temporarily making joints at the construction site, and can effectively ensure the sealing performance of the pipe when the length changes due to cold and heat, and the cost is low.
