Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the disclosed embodiments are merely exemplary of the invention, and are not intended to limit the invention to the precise embodiments disclosed. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The invention will be further described in the following with reference to specific embodiments thereof,

as shown in fig. 1-4, a slider-mounting mold for a slider without a pulling piece comprises a support 1 fixed on a zipper head-mounting machine, wherein in the apparatus, the slider is fed to a positioning opening 11 on the support 1 in a state that a protrusion 0 is downward, the protrusion 0 on the slider extends into the support 1 through the positioning opening 11 and is positioned at a clamping opening 22 between clamping blocks 21 of a positioning piece 2 in the support 1, and the positioning pieces 2 are close to each other to enable the clamping blocks 21 to clamp the protrusion 0 on the slider, thereby playing a role of fixing the position of the slider in the slider-mounting mold.

As shown in fig. 4, in the support 1, the driving device 4 can control the push rod 3 to move up and down in the socket 23, and because the socket 23 is opened downwards, the push rod 3 can push the inclined surface inside the socket 23 to push the positioning member 2 away when moving upwards.

As a modified example, the push rod 3 pushes the positioning member 2 to move through the push surface 32 on the projection 31, and the arc-shaped push surface 32 makes the projection 31 move in contact with the inclined surface in the insertion opening 23 more smoothly, and reduces the resistance of the projection 31 during moving, so that the positioning member 2 is pushed more easily.

As an improved embodiment, the clamping blocks 21 on the positioning members 2 which are close to each other can better clamp the convex part 0 of the slider between the clamping openings 22 when the positioning members 2 are close to each other, when the convex block 31 of the mandril 3 passes through the inserting opening 23 between the positioning members 2 and extends into the supporting groove 25, the supporting surfaces 24 are abutted against the two sides of the convex block 31, at the moment, the distance between the positioning members 2 reaches the maximum, and the positioning members 2 can not be pushed open by the mandril 3 any more.

As a modified embodiment, the support 1 fixes the position of the driving device 4 in the upper puller die through the installation groove 12, so that the driving device 4 is prevented from generating position deviation due to stress when controlling the ejector rod 3 to move, and the ejector rod 3 cannot push the positioning piece 2 at the correct position.

As shown in fig. 3-4, since the limiting block 5 is fixed on the support 1, the spring in the limiting groove 26 of the positioning element 2, which abuts between the positioning element 2 and the limiting block 5, generates a pushing force on the positioning element 2, so that the positioning element 2 tends to approach each other, and the clamping blocks on the positioning element 2 can stably clamp the protrusion 0 of the slider in the clamping opening 22. Wherein, the positioning piece 2 can be provided with a slotted hole for accommodating a spring in the limiting groove 26, the spring is placed in the slotted hole and props against the limiting block 5 in the limiting groove 26 after extending out, and the slotted hole can prevent the spring from being separated from the positioning piece 2 and the limiting block 5.

As an improved embodiment, on the support 1, the screw is screwed to adjust the distance between the limiting block 5 and the positioning element 2, thereby changing the compression degree of the spring between the positioning element 2 and the limiting block 5, further adjusting the pressure applied to the protruding part 0 by the clamping block 21 on the positioning element 2 when clamping the protruding part 0 of the slider, and simultaneously performing adaptive adjustment on the minimum distance between the clamping blocks 21 according to the thickness of the protruding part 0 of the slider, avoiding the phenomenon that the protruding part 0 of the slider is crushed due to excessive pressure when being clamped,

As a modified embodiment, when the slider is fed into the upper slider mold, in the support 1, besides the convex part 0 of the slider is clamped by the clamping block 21, the convex part 0 of the slider partially butts into the positioning groove 13 after passing through the positioning opening 11, the orientation of the slider can be positioned and supported through the positioning groove 13, and the slider is prevented from swinging due to uneven stress when the convex part 0 is clamped by the clamping block 21.

In conclusion, the zipper puller installing die can be suitable for installing a puller on a puller without a pulling piece in a zipper puller installing machine, the puller without the pulling piece is fixed in the process of installing the puller, the phenomenon that the puller cannot be smoothly sent into a chain belt due to unstable positioning of the puller in the process of installing the puller is avoided, and the effect of expanding the range of products used by the zipper puller is effectively achieved.

The above embodiment is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited in this way, so: all equivalent changes made according to the structure, shape and principle of the utility model should be covered within the protection scope of the utility model.
