Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but this utility model is not limited to these embodiments.
As it is shown in figure 1, this one reset and protection mechanism includes base plate 100, lower mold 200 and upper mold 300, above-mentioned lower mold
200 are arranged on base plate 100 and upper mold 300 is arranged in lower mold 200, are formed for producing between upper mold 300 and lower mold 200
The injection die cavity of product molding, is additionally provided with ejector pin component between base plate 100 and lower mold 200, and the upper end of ejector pin component passes down
Mould 200 is also positioned at injection molding intracavity, and the lower end of ejector pin component is connected with base plate 100, during utility model works, produces
Product can outwards be ejected injection die cavity in injection molding intracavity molding and by above-mentioned ejector pin component by product.
Preferably, the quantity of above-mentioned ejector pin component is four groups, and four groups of ejector pin component are that square is respectively arranged at base plate 100
And between lower mold 200, it is ensured that the stationarity that thimble moves when ejector pin component outside ejecting product, it is to avoid product clamping stagnation occurs
Even result in product and the generation of damage phenomenon occurs, it is ensured that normal work of the present utility model.
Further, above-mentioned ejector pin component includes needle plate 400 and lower needle plate 410, is provided with thimble on upper needle plate 400
And thimble one end passes lower mold 200 and stretches into injection molding intracavity, lower needle plate 410 is positioned at lower section and the lower needle plate 410 of needle plate 400
Two ends contact with upper needle plate 400 and base plate 100 respectively, in the course of the work, upper needle plate 400 can drive thimble outwards to eject product
Product, it is ensured that this utility model energy automatic ejection product, it is ensured that normal work of the present utility model.
Being provided with release link 500 in lower mold 200, the upper end of release link 500 contacts with upper needle plate 400, release link 500
Lower end is through lower mold 200 and is inserted on needle plate 400, and during this utility model matched moulds, upper mold 300 is in the mistake declined
Cheng Zhongneng first contacts with release link 500, it is to avoid upper mold 300 directly contacts with thimble and causes ejector pin component abrasion occur or damage
The generation of phenomenon, improves the service life of ejector pin component.
Preferably, the lower end in release link 500 is fixed with the diameter of limiting section 510 and limiting section 510 more than release link 500
Diameter, upper needle plate 400 offers the stopper slot 401 corresponding with limiting section 510, release link 500 can drive limiting section 510
Move in stopper slot 401, stopper slot 401 and the movement that restriction release link 500 in the vertical direction is set of limiting section 510,
