Abstract
The utility model discloses a kind of injection machine nozzle, comprise the injection nozzle of a cone shape, described injection nozzle has the loophole of a taper, loophole position is provided with internal thread part, and the positioning cap of an Openworks shape is combined with by this internal thread part, described positioning cap has a shrinkage pool, ball sealer is provided with in described shrinkage pool, described ball sealer with at the bottom of the hole of this shrinkage pool between have a locking spring mutually, the diameter of described ball sealer is greater than the minimum diameter of described loophole, when described locking spring is releived, described ball sealer deduction is in described loophole, and form sealing, this device after injection moulding completes, can be closed loophole, avoids in the spilling of stopping the molten plastic under note state.
Description
Technical field
The utility model relates to a kind of injection machine nozzle.
Background technology
Injection machine nozzle is a kind of necessary parts spraying molten plastic, existing injection machine nozzle different, but when the demoulding of plastics plastic, injection machine nozzle is still in a kind of spray regime, therefore the molten plastic having part overflows, and causes waste.
Therefore existing injection machine nozzle needs to improve.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of injection machine nozzle, and this device after injection moulding completes, can be closed loophole, avoids in the spilling of stopping the molten plastic under note state.
For solving the problem, the utility model adopts following technical scheme:
A kind of injection machine nozzle, comprise the injection nozzle of a cone shape, described injection nozzle has the loophole of a taper, loophole position is provided with internal thread part, and the positioning cap of an Openworks shape is combined with by this internal thread part, described positioning cap has a shrinkage pool, ball sealer is provided with in described shrinkage pool, described ball sealer with at the bottom of the hole of this shrinkage pool between have a locking spring mutually, the diameter of described ball sealer is greater than the minimum diameter of described loophole, when described locking spring is releived, described ball sealer deduction in described loophole, and forms sealing.
As preferred technical scheme, described injection nozzle is spherical near one end of described loophole position.
As preferred technical scheme, described positioning cap is steel.
As preferred technical scheme, described injection nozzle is provided with away from the inwall of one end of described loophole the first female threaded joint connecting injection machine.
The beneficial effects of the utility model are: this device is when injecting, loophole is relative with mould, under the reaction force of mould, ball sealer is compressed in loophole inside, and now loophole opens beginning injection moulding, after injection moulding completes, mould and nozzle depart from, and at this moment under the effect of locking spring, ball sealer ejects, loophole is sealed, avoids in the spilling of stopping the molten plastic under note state.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of positioning cap.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult a kind of injection machine nozzle shown in Fig. 1 and Fig. 2, comprise the injection nozzle 1 of a cone shape, described injection nozzle 1 has the loophole 101 of a taper, loophole 101 position is provided with internal thread part, and the positioning cap 2 of an Openworks shape is combined with by this internal thread part, described positioning cap 2 has a shrinkage pool 201, ball sealer 3 is provided with in described shrinkage pool 201, described ball sealer 3 with at the bottom of the hole of this shrinkage pool 201 between have a locking spring 4 mutually, the diameter of described ball sealer 3 is greater than the minimum diameter of described loophole 101, when described locking spring 4 is releived, described ball sealer 3 deducts in described loophole 101, and form sealing.
A preferred embodiment in the utility model, described injection nozzle 1 is spherical near one end of described loophole 101 position.
A preferred embodiment in the utility model, described positioning cap 2 is steel.
A preferred embodiment in the utility model, described injection nozzle 1 is provided with away from the inwall of one end of described loophole 101 the first female threaded joint 111 connecting injection machine.
The beneficial effects of the utility model are: this device is when injecting, loophole is relative with mould, under the reaction force of mould, ball sealer is compressed in loophole inside, and now loophole opens beginning injection moulding, after injection moulding completes, mould and nozzle depart from, and at this moment under the effect of locking spring, ball sealer ejects, loophole is sealed, avoids in the spilling of stopping the molten plastic under note state.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
