Description

Flat thimble moves back coupler mechanism

【Technical field】

The present invention relates to a kind of ejector pin mechanism, and in particular to a kind of flat thimble moves back coupler mechanism.

【Background technology】

When producing plastic cement products, the small volume of some products, by a definite limitation on mould die sinking time space, use Oblique top exits intensity again can be very weak, easily broken, and without production, product 10 as shown in Figure 1, the both sides of the product 10 have snap fit 11, due to snap fit 11 also very little, snap fit amount typically in below 1mm, thus can not almost do the situation of small oblique top and due to production The both sides of product 10, which all have snap fit 11 its oblique top situation, can also interfere.

In view of this, it is necessary to provide a kind of mechanism in fact so that can be safe in the case of product and its snap fit are less Exit, reach the effect of volume production.

【The content of the invention】

In order to achieve the above object, the present invention provides a kind of flat thimble and moves back coupler mechanism, and it is applied to exit production in mould Product and its less situation of snap fit, the mould include from top to down：Caster, mother module core, male die core, male template, upper ejector retainner plate And lower ejector retainner plate, the flat thimble, which moves back coupler mechanism, to be included：

Some flat thimbles, its main body in the male die core and male template, the flat thimble top with the synthesis type product, Snap fit of the one side of the flat thimble with the synthesis type product simultaneously abuts the male die core hole wall, and the lower end of the flat thimble passes through institute State ejector retainner plate to be fixed on the lower ejector retainner plate, the flat thimble is elastomeric material；

First inclined-plane, on the another side of the flat thimble, first inclined-plane is located at below the product snap fit simultaneously for it In the male die core；

Second inclined-plane, it is on the one side of the flat thimble and parallel with first inclined-plane, and second inclined-plane is set In the lower section on first inclined-plane and in the male template；

3rd inclined-plane, it is located on the another side of the flat thimble and, threeth inclined-plane symmetrical with first inclined-plane Below second inclined-plane and in the male template.

Preferably, the horizontal range on second inclined-plane is more than the snap fit amount of the product.

Preferably, the distance that second inclined-plane upper end moves to the male die core lower end is more than first inclined-plane upper end With the distance on the flat thimble top.

Preferably, the flat thimble width between second inclined-plane and the 3rd inclined-plane is less than the diameter in the male die core hole.

Preferably, the distance that the 3rd inclined-plane upper end moves to the male die core lower end is more than the upper ejector retainner plate motion To the distance of the male template lower end.

Preferably, being respectively equipped with the gradient on the flat thimble two sides, the gradient is located at the 3rd inclined-plane lower section and position In the male template.

Preferably, the elastomeric material is spring steel.

Compared to prior art, the flat thimble of the present invention moves back coupler mechanism, by setting three on flexible flat thimble Individual inclined-plane realizes that there is product smaller snap fit to exit, and the mechanism structure is simple, processing and easy for installation, and intensity is good and have Production.

【Embodiment】

The better embodiment of the present invention is described in further detail below with accompanying drawing.

The present invention provides a kind of flat thimble and moves back coupler mechanism, and it is applied to exit product and its less feelings of snap fit in mould Condition, it refer to shown in Fig. 1, the mechanism is used to exit shaped article 10, and the both sides of product 10 all have snap fit 11, and its snap fit amount is about For 1mm, refer to shown in Fig. 2 and Fig. 3, the mould includes from top to down：Caster 200, mother module core 210, male die core 310, public affairs Template 300, upper ejector retainner plate 400 and lower ejector retainner plate 500, the flat thimble, which moves back coupler mechanism, to be included：

Some flat thimbles 100, its main body in the male die core 310 and male template 300, match somebody with somebody by the flat top of thimble 100 The synthesis type product 10, the snap fit 11 of the one side of the flat thimble 100 with the synthesis type product 10 simultaneously abut the male die core 310 Hole wall, the lower end of the flat thimble 100 is fixed on the lower ejector retainner plate 500 through the upper ejector retainner plate 400, the flat thimble 100 be spring steel；

First inclined-plane 110, on the another side of the flat thimble 100, first inclined-plane 110 is located at the product 10 for it The lower section of snap fit 11 is simultaneously located in the male die core 310；

Second inclined-plane 120, it is on the one side of the flat thimble 100 and parallel with first inclined-plane 110, and this Two inclined-planes 120 are located at the lower section on first inclined-plane 110 and in the male template 300；

3rd inclined-plane 130, it is on the another side of the flat thimble 100 and symmetrical with first inclined-plane 110, should 3rd inclined-plane 130 is located at the lower section of the second inclined-plane 120 and in the male template 300.

Wherein, the horizontal range S2 on second inclined-plane 120 is more than the snap fit amount S1 of the product.

Wherein, the upper end of the second inclined-plane 120 move to the lower end of male die core 310 distance A1 be more than it is described first oblique The distance A2 of the upper end of face 110 and the flat top of thimble 100.

Wherein, the flat thimble width B2 between the inclined-plane 130 of the second inclined-plane 120 and the 3rd is less than the male die core 310 The diameter B1 in hole.

Wherein, the upper end of the 3rd inclined-plane 130 moves to the distance C1 of the lower end of male die core 310 and is more than the upper thimble Plate 400 moves to the distance C2 of the lower end of male template 300.

Wherein, Fen Do are provided with the gradient 140 Shang the two sides of flat thimble 100, and the gradient 140 is located at the 3rd inclined-plane 130 lower sections are simultaneously located in the male template 300.

It refer to shown in Fig. 4, in the present embodiment, when the flat thimble moves back coupler mechanism die sinking, lower ejector retainner plate 500 drives flat Thimble 100 moves upwards, and when flat 100 upward move distance of thimble is A1, the upper end on the second inclined-plane 120 moves to male die core 310 lower end, now flat thimble 100 product 10 has been ejected to A1 distance upwards, because A1 is more than A2, the first inclined-plane 110 The male die core 310 is gone out；Lower ejector retainner plate 500 continues up, and starts the second inclined-plane 120 heading into the male die core 310 Hole, because the one side of the flat thimble 100 abuts the hole wall of male die core 310, due to the second inclined-plane 120, flat thimble 100 is in public affairs Side in template 300 is more than the border in the hole of male die core 310, and due to the first inclined-plane 110, flat thimble 100 is in male template 300 Opposite side is less than the border in the hole of male die core 310, while under the elastic reaction of the gradient 140 and spring steel, force flat thimble 100 to Its curving deforms, so as to start the snap fit 11 for driving flat thimble 100 to exit product 10, because B2 is less than B1, and now flat top Pin 100 may proceed to move upwards, and when upper ejector retainner plate 400 has moved C2 stop motions, now flat thimble 100 has completely disengaged product 10 snap fit 11, mechanism die sinking are completed.

It is noted that the invention is not restricted to above-mentioned embodiment, any person skilled in the art is based on this hair Any simple modification, equivalent change and modification that bright technical scheme is made to above-described embodiment, both fall within the protection model of the present invention In enclosing.
