One end of described resetting-mechanism links to each other with described cope match-plate pattern, and the other end links to each other with described ejector retainner plate;
Be fixed with thimble and return pin on the described ejector retainner plate.
Preferably, described ejector retainner plate comprises ejector retainner plate and following ejector retainner plate, and the described upper end of ejector retainner plate down links to each other with described resetting means, and the described lower end of ejector retainner plate down links to each other with described return pin with described thimble.
Preferably, described going up on the ejector retainner plate offers first cavity that is complementary with described thimble and second cavity that is complementary with described return pin.
Preferably, described resetting means is spring, pneumatic mechanism or calutron.
Pass through technique scheme, the beneficial effect of technical solutions of the utility model is: a kind of thimble stripper apparatus, comprise front template, described front template is provided with preceding die, offer cavity on described front template and the described preceding die, be equiped with ejector pin mechanism in the described cavity, described ejector pin mechanism comprises thimble, resetting-mechanism, ejector retainner plate and return pin; One end of described resetting-mechanism links to each other with described cope match-plate pattern, and the other end links to each other with described ejector retainner plate; Be fixed with thimble and return pin on the described ejector retainner plate.Adopt described thimble stripper apparatus, by the cooperation of resetting means and thimble, can realize product stripping easily, by the effect of return pin, realize return again, apparatus structure is simple, processes simple and convenient.

The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of thimble stripper apparatus of simple in structure, easy making process.
Embodiment,
As Fig. 1, as Fig. 2 and as shown in Figure 3, a kind of thimble stripper apparatus, comprise front template 1, described front template 1 is provided with preceding die 2, offers cavity on described front template 1 and the described preceding die 2, is equiped with ejector pin mechanism 3 in the described cavity, described ejector pin mechanism 3 comprises thimble 31, resetting-mechanism-spring 32, ejector retainner plate 33 and return pin 34, one end of spring 32 links to each other with front template 1, and the other end links to each other with ejector retainner plate 33, is fixed with thimble 31 and return pin 34 on the ejector retainner plate 33.
Wherein, ejector retainner plate 33 comprises ejector retainner plate 331 and following ejector retainner plate 332, the upper end of following ejector retainner plate 332 links to each other with spring 32, the lower end of following ejector retainner plate 332 links to each other with return pin 34 with thimble 31, offers first cavity that is complementary with thimble 31 and second cavity that is complementary with return pin 34 on last ejector retainner plate 331.
Its operation principle is: mould is after finishing filling, begin normal die sinking, owing in the front template 1 spring 32 is housed, when front mould separates with the back mould, spring 32 ejects ejector retainner plate 33, and the thimble 31 on the ejector retainner plate 33 directly acts on product surface, product is ejected break away from preceding die shape chamber, product is trapped in die surface, back, is convenient to take out.
After product took out, front mould needed matched moulds with the back mould, finishes mould filling next time.When die surface, back touched the return pin 34 of front mould, the ejector retainner plate 33 that is equiped with return pin 34 was pushed back, thimble 31 returns, and mould returns to the matched moulds state, can begin the injection mo(u)lding of next round.
Involved resetting means in the utility model except spring 32, can also be pneumatic means or calutron, and concrete embodiment is determined on a case-by-case basis, and does not do any qualification at this utility model.
Adopt the beneficial effect of technical solutions of the utility model to be: a kind of thimble stripper apparatus, comprise front template 1, described front template 1 is provided with preceding die 2, offer cavity on described front template 1 and the described preceding die 2, be equiped with ejector pin mechanism 3 in the described cavity, described ejector pin mechanism 3 comprises thimble 31, resetting-mechanism, ejector retainner plate 33 and return pin 34; One end of described resetting-mechanism links to each other with described cope match-plate pattern 1, and the other end links to each other with described ejector retainner plate 33; Be fixed with thimble 31 and return pin 34 on the described ejector retainner plate 33.Adopt described thimble stripper apparatus, by the cooperation of resetting means and thimble 31, can realize product stripping easily, by the effect of return pin 34, realize return again, apparatus structure is simple, processes simple and convenient.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
