Abstract
Disclosed is an injection mould structure of an inner wall of a pipe joint, which is characterized in that a bolt (1) is positioned on one end; the other end is provided with an injection port (3), an injection pipe (4) and a plastic output port (5), and an injection axis (6) top jointed with the bolt (1) and a fixing nut (2) of an injection axis (6); an integral form is realized between the injection axis (6) and the fixing nut (2). The utility model has the advantages of an integral forming of a liner pipe of the pipe joint, easy operation and no injected plastic silk adhibiting to a screw thread in the pipe joint.
Description
Technical field
The utility model relates to a kind of injection mold structure of pipe joint inwall.
Background technology
Present injection mo(u)lding to the pipe joint internal lining pipe, main Shi Yong Lying formula injection machine Shi Yong Lying formula injection machine carries out injection mo(u)lding to the internal lining pipe of pipe joint, the internal lining pipe of the mould of loosing core that need inhale Clamp-on spare with the band electromagnet after to injection mo(u)lding loosed core, and after loosing core, the internal thread of pipe joint is stained with the plastics silk of injection moulding, also needs the plastics silk of pipe joint internal thread is removed; The mould of loosing core that the band electromagnet is inhaled Clamp-on spare costs an arm and a leg, and various pipe joint needs the different moulds of loosing core, and each specification bore of pipe joint all needs seven molds, makes that the cost to the injection mo(u)lding of pipe joint internal lining pipe significantly increases; The plastics silk of pipe joint internal thread removed also needs to drop into more labour.
Summary of the invention
In order to address the above problem, the utility model proposes a kind of injection mold structure of cheap pipe joint inwall, to the injection moulding one-shot forming of pipe joint internal lining pipe, there is not the pipe joint internal thread to be stained with the problem of the plastics silk of injection moulding.
The technical scheme that its technical problem that solves the utility model adopts is: the injection mold structure of pipe joint inwall is characterized in that: the one end is a bolt; The other end is to be provided with injection hole, injection moulding pipeline and to go out to mould mouth, and pushes up the injection moulding axle that closes with bolt, and the hold-down nut of injection moulding axle.
When pipe joint was straight joint, injection moulding axle and hold-down nut were one-body molded.
The beneficial effects of the utility model are: use the utility model to the moulding of pipe joint internal lining pipe integrated through injection molding, method of operating is simple, and does not have the pipe joint internal thread to be stained with the problem of the plastics silk of injection moulding.
Description of drawings
Fig. 1 is the utility model embodiment one cutaway view.
Fig. 2 is the utility model embodiment two cutaway views.
Fig. 3 goes out to mould the profile of mouth for the utility model.
Among the figure: 1. bolt, 2. hold-down nut, 3. injection hole, 4. the injection moulding pipeline 5. goes out to mould mouth,
6. injection moulding axle, 7. inner-walls of duct, 8. pipe joint.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment one
As Fig. 1, shown in Figure 3, the injection mold structure of pipe joint 8 inwalls, one end are bolts 1; The other end is to be provided with injection hole 3, injection moulding pipeline 4 and to go out to mould mouth 5, and pushes up the injection moulding axle 6 that closes with bolt 1, and the hold-down nut 2 of injection moulding axle 6; Earlier bolt 1 and pipe joint 8 one end internal threads are screwed, the injection moulding axle is inserted from pipe joint 8 other ends, injection moulding axle 6 is one-body molded with hold-down nut 2, hold-down nut 2 screws with the internal thread of this end, make injection moulding axle 6 and bolt 1 top close, by injection hole 3, injection moulding pipeline 4 with go out to mould mouthfuls 5 toward inner-walls of duct 7 injection mouldings, after the injection moulding, pull down bolt 1 and injection moulding axle 6, then form an inner lining plastic tube at inner-walls of duct 7.
Embodiment two
As Fig. 2, shown in Figure 3, the injection mold structure of pipe joint 8 inwalls, one end are bolts 1; The other end is to be provided with injection hole 3, injection moulding pipeline 4 and to go out to mould mouth 5, and pushes up the injection moulding axle 6 that closes with bolt 1, and the hold-down nut 2 of injection moulding axle 6; Earlier bolt 1 and pipe joint 8 one end internal threads are screwed, the injection moulding axle is inserted from pipe joint 8 other ends, hold-down nut 2 entangles injection moulding axle 6, hold-down nut 2 screws with the internal thread of this end, makes injection moulding axle 6 and bolt 1 top close, and blocks the injection moulding axle simultaneously, by injection hole 3, injection moulding pipeline 4 with go out to mould mouthfuls 5 toward inner-walls of duct 7 injection mouldings, after the injection moulding, pull down bolt 1 and injection moulding axle 6, then form an inner lining plastic tube at inner-walls of duct 7.
Claims (2)
1. the injection mold structure of pipe joint inwall, it is characterized in that: the one end is bolt (1); The other end is to be provided with injection hole (3), injection moulding pipeline (4) and to go out to mould mouthful (5), and pushes up the injection moulding axle (6) that closes with bolt (1), and the hold-down nut (2) of injection moulding axle (6).
2. the injection mold structure of pipe joint inwall according to claim 1 is characterized in that: when pipe joint was straight joint, injection moulding axle (6) was one-body molded with hold-down nut (2).
