Therefore, the position of penetrator is very unimportant before not penetrating, owing to produce continuously, therefore, if slider of zipper fastener A position behind penetrator is improper, then when ending the matched moulds ejaculation up and down, often penetrate bad, and may be with the slider of zipper fastener crushing, and even mould be impaired, forms the puzzlement on producing.

In view of this, to be this in all the year round be engaged in the applicant that slide fastener production equipment and mould are researched and developed and the experience of production and marketing, and cover the fact your office gets permission multinomial patent, concentrate on studies, phase can overcome above-mentioned disappearance, through exploring repeatedly, firstly appear and make " top stop and bottom stop of closed-end zipper ejaculation checking device " of the present utility model.

The purpose of this utility model is, provides a kind of top stop and bottom stop of closed-end zipper to penetrate checking device, and it can effectively promote the yield of product.

A kind of closed-end zipper of the utility model penetrates checking device up and down, it is characterized in that it is that to penetrate the counterdie normal condition in the correspondence that penetrates patrix be chain between cog headroom position, is provided with one and detects prominent tenon, this detects prominent tenon and links a stage clip, and can with respect to last mould body open outward or in contract; And mat one detecting switch is linked to this and detects prominent tenon, so that when moving up and down if detect prominent tenon pressurized during matched moulds, but the detecting switch perception and the person that sends the signal.

Detecting switch wherein is to be microswitch.

Detecting switch wherein is to be optoelectronic switch, metal detection or other sensing devices.

Wherein said slide fastener is to be metal, nylon or plastic cement slide fastener.

Patrix wherein must be provided with location and pressure setting.

For further disclosing concrete technology contents of the present utility model and effect, at first see also diagram, wherein:

Fig. 1 is the slide fastener schematic diagram before not penetrating behind the penetrator;

Fig. 2 penetrates back formation closed-end zipper schematic diagram for ending up and down;

Fig. 3 turns over the top view of turnback for jetting mold patrix of the present utility model;

Fig. 4 turns over the front view of turnback for patrix;

Fig. 5 turns over the side view of turnback for patrix;

Fig. 6 is the schematic diagram that penetrates in chain belt when location of counterdie.

As shown in Figure 3, basically, checking device of the present utility model is to be arranged at patrix when turning over the turnback announcement, the face that detects (line) P of the non-sprocket suitable position of its two chain interbands when locating corresponding to the counterdie chain belt, be provided with one and detect prominent tenon 1, and this detects prominent tenon 1 to form the wedge shape inclined-plane with axe be good, so that form a wire, that is it outwards is sharp inclined-plane, and is sleeved on die ontology and is removable state.And its inside then links a stage clip 2, and an end of this stage clip 2 is to be fixed on the mould, and detects prominent tenon 1 and be a default distance with aforesaid, that is, when detecting prominent tenon 1 when contracting in stressed, can touch stage clip 2.

Detect prominent tenon 1 simultaneously and also be linked to a detecting switch 3; this detecting switch 3 can touch and perception when prominent tenon 1 pressurized moves up and down in detecting; and send signal such as buzzer etc. in the sequencing mode; and can and then be linked to the disposal of board switch for shutting down, this detecting switch can be with microswitch, optoelectronic switch, metal detector or other sensing devices for it.
