Description

Bottle cap pressing injector sealing configuration

Technical field:

The utility model relates to bottle cap pressing injector field of sealing technology, particularly a kind of bottle cap pressing injector sealing configuration.

Background technique:

The production process of general bottle cap pressing injector is: extrude, and---scraping disc scraper is in external mold, and---internal mold is by oil pressure pressure injection matched moulds, and------------internal mold moves up and down the demoulding on french curves, and------lid cooling---goes out product to deliver to lid track in qi of chong channel ascending adversely in the demoulding in running water cooling.As shown in Figure 1, in water cooling link, between original intake pipe and mould, the main O RunddichtringO that leans on seals, because bottle cap pressuring machine mould can produce vibration in the upper and lower piston movement process of pressure injection, long-time use can cause seal ring aging, produce at O RunddichtringO place and leak, the water circulation in pressure injection process can be affected like this; Secondly, original mould and sealing place of pressure injection piston flat surface, due to poorly sealed, usually can be leaked.

The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.

Model utility content:

The purpose of this utility model is to provide a kind of bottle cap pressing injector sealing configuration, thus overcomes above-mentioned defect of the prior art.

For achieving the above object, the utility model provides:

Bottle cap pressing injector sealing configuration, mould intake pipe is connected with adopting pipe dental structure between mould and scribbles sealant sealing, pressure injection piston and mould are corresponding is on the contact surface provided with concave, convex groove structure, be provided with O RunddichtringO in described groove, described tongue to insert in groove and contacts with O RunddichtringO.

Compared with prior art, the utility model has following beneficial effect:

Mould intake pipe is connected with adopting pipe dental structure between mould and scribbles sealant sealing, solves bottle cap pressuring machine mould in the past and in pressure injection upper and lower piston movement process, produces vibration make O RunddichtringO produce aging phenomenon, extend product working life; Pressure injection piston and mould adopt tongue and groove to add O RunddichtringO on the contact surface and seal, and prevent from leaking.

Accompanying drawing illustrates:

Fig. 1 is existing bottle cap pressing injector sealed structural representation;

Fig. 2 is according to bottle cap pressing injector sealed structural representation of the present utility model;

Fig. 3 is the A portion enlarged view of Fig. 2;

Main Reference Numerals illustrates:

1-pressure injection piston, 2-mould intake pipe, 3-mould, 4-pipe tooth, 5-groove, 6-tongue, 7-O RunddichtringO.

Embodiment:

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.

Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.

As Figure 2-3, according to the bottle cap pressing injector sealing configuration of the utility model embodiment, adopt pipe tooth 4 anatomical connectivity between mould intake pipe 2 and mould 3 and scribble sealant sealing, solve bottle cap pressuring machine mould in the past in pressure injection upper and lower piston movement process, to produce vibration make O RunddichtringO produce aging phenomenon, extend product working life; Pressure injection piston 1 and mould 3 are corresponding is on the contact surface provided with concave, convex groove structure, is provided with O RunddichtringO 7 in described groove 5, and described tongue 6 to insert in groove 5 and contacts with O RunddichtringO 7, prevents from leaking.

This kind of bottle cap pressing injector sealing configuration, structure is simple, good seal performance, long service life, is not easy often to change product component, cost-saving, has good promotional value.

The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
