[specific embodiment]

Below with accompanying drawing, better embodiment of the present utility model is described in further detail.

The utility model provides a kind of flat thimble to move back fastening hook mechanism, it is applied in mould exit product and the less situation of grab thereof, please refer to shown in Fig. 1, this mechanism is for exiting shaped article 10, these product 10 both sides all have grab 11, and its grab amount is about 1mm, please refer to shown in Fig. 2 and Fig. 3, this mould comprises from top to down: caster 200, mother module core 210, male die core 310, male model plate 300, upper ejector retainner plate 400 and lower ejector retainner plate 500, and this flat thimble moves back fastening hook mechanism and comprises:

Some flat thimbles 100, its main body is located in described male die core 310 and male model plate 300, these flat thimble 100 tops coordinate this product 10 of moulding, one side of this flat thimble 100 coordinates the grab 11 of this product 10 of moulding and near the hole wall of described male die core 310, the lower end of this flat thimble 100 is fixed on described lower ejector retainner plate 500 through described upper ejector retainner plate 400, and this flat thimble 100 is spring steel;

The first inclined-plane 110, it is located on the another side of described flat thimble 100, and this first inclined-plane 110 is located at the below of these product 10 grabs 11 and is arranged in described male die core 310;

The second inclined-plane 120, it is located on a side of described flat thimble 100 and is parallel with described the first inclined-plane 110, and this second inclined-plane 120 is located at the below on described the first inclined-plane 110 and is arranged in described male model plate 300;

The 3rd inclined-plane 130, its be located on the another side of described flat thimble 100 and with described the first inclined-plane 110 symmetries, the 3rd inclined-plane 130 is located at 120 belows, described the second inclined-plane and is arranged in described male model plate 300.

Wherein, the horizontal range S2 on described the second inclined-plane 120 is greater than the grab amount S1 of this product.

Wherein, the distance A 1 that 120 upper ends, described the second inclined-plane move to described male die core 310 lower ends is greater than the distance A 2 on 110 upper ends, described the first inclined-plane and described flat thimble 100 tops.

Wherein, the flat thimble width B 2 between described the second inclined-plane 120 and the 3rd inclined-plane 130 is less than the diameter B1 in described male die core 310 holes.

Wherein, the distance C 1 that 130 upper ends, described the 3rd inclined-plane move to described male die core 310 lower ends is greater than the distance C 2 that described upper ejector retainner plate 400 moves to described male model plate 300 lower ends.
