[0002] As an indispensable mechanism in the automatic chain threading machine, the upper slider mold is used to position and convey the slider for the chain threading machine. Therefore, the stability of the slider conveying must be ensured during the conveying process. The existing upper slider mold does not take any stabilizing measures for the conveying of the slider, which makes the existing upper slider mold's slider conveying stability insufficient. Summary of the invention

[0003] In view of the above problems, the present invention provides a slider positioning mold, which has the advantages of simple structure and can stabilize the slider.

[0004] The purpose of the utility model is achieved in this way:

[0005] A slider positioning mold, comprising a mold base, wherein the upper end of the mold base is formed with a parallel chain end positioning groove, the front end of the parallel chain end positioning groove is formed with an open chain end positioning groove, and the upper end surface of the parallel chain end positioning groove is flush with the upper end surface of the lower baffle plate of the slider;

[0006] The open chain end positioning groove is formed by the opposite ends of the two slides, and the opposite ends of the two slides are formed with arc-shaped grooves, which are adapted to the side arc of the slider. The front end distance of the two arc-shaped grooves is smaller than the maximum spacing on both sides of the slider, and the upper end surface of the slide is flush with the lower end surface of the chain tooth channel of the slider.

[0007] By arranging the upper end surface of the chain end positioning groove to be flush with the upper end surface of the lower baffle of the slider and the upper end surface of the slide plate to be flush with the lower end surface of the slider's sprocket channel, the slider positioning groove on the mold can fit the slider as closely as possible and the wrapping height is maximized. It can also guide the chain belt when threading the chain, making the contact area of ​​the cloth belt larger and the guiding distance longer; and by designing that the front end distance of the arc groove is smaller than the maximum spacing between the two sides of the slider, the arc groove half-wraps the slider, making the slider more stable.

[0008] The utility model is further configured as follows: a slide groove for sliding two slide plates is formed on the upper end of the mold seat, and the two slide plates slide toward each other to change the distance between the two arc-shaped grooves, thereby changing the size of the open chain end positioning groove.

[0009] Through the design of the slide plate, the size of the positioning groove at the open chain end can be changed to adapt to pull heads of different sizes.

[0010] The utility model is further configured as follows: a clamping device for bringing the two slide plates closer to each other is provided on the mold seat.

[0011] The clamping device can be set to clamp the pull head, which can play a stabilizing role when conveying the pull head and threading the chain.

[0012] The utility model is further configured as follows: the clamping device comprises clamping cylinders arranged on both sides of the mold base, and the extended ends of the clamping cylinders extend toward each other and respectively abut against both sides of the two slide plates.

[0013] The clamping cylinder is used as a clamping device and is suitable for installing the slider into the slider positioning groove from above. After the slider is installed into the positioning groove, the clamping cylinder controls the slide plates to approach each other and clamp the slider.

[0014] The utility model is further configured as follows: the clamping device comprises a spring arranged in the slide groove, and the spring always gives the two slide plates a force to approach each other.

[0015] The spring is used as a clamping device and is suitable for the slider to enter from the front of the positioning groove at the open chain end. When the slider enters, since the front end distance of the two arc-shaped grooves is smaller than the maximum spacing on both sides of the slider, the slider will move the two slides away from each other to open the positioning groove. When the slider enters, the two slides will approach each other under the action of the spring and clamp the slider. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The open chain end positioning groove 3 is formed by the opposite ends of two slide plates 6, and the opposite ends of the two slide plates 6 are formed with arc-shaped grooves 7, which are adapted to the side arc of the slider. The front end distance of the two arc-shaped grooves 7 is smaller than the maximum spacing on both sides of the slider, and the upper end surface of the slide plate 6 is flush with the lower end surface of the chain tooth channel 8 of the slider.

[0024] By arranging the upper end surface of the chain end positioning groove 2 to be flush with the upper end surface of the lower baffle plate 5 of the slider and the upper end surface of the slide plate 6 to be flush with the lower end surface of the slider's sprocket channel 8, the slider positioning groove on the mold can fit the slider as closely as possible, and the wrapping height is maximized. It can also guide the chain belt when threading the chain, making the contact area of ​​the cloth belt larger and the guiding distance longer; and by designing that the front end distance of the arc-shaped groove 7 is smaller than the maximum spacing between the two sides of the slider, the arc-shaped groove 7 half-wraps the slider 4, making the slider more stable.

[0025] The upper end of the mold base 1 is formed with a slide groove 9 for two slide plates 6 to slide. The two slide plates 6 slide toward each other to change the distance between the two arc-shaped grooves 7, thereby changing the size of the open chain end positioning groove 3. Through the design of the slide plate, the size of the open chain end positioning groove can be changed to adapt to sliders of different sizes.

[0026] The mold base 1 is provided with a clamping device for bringing the two slide plates 2 closer to each other. Through the arrangement of the clamping device, the pull head can be clamped, which can play a stabilizing role when conveying the pull head and threading the chain.
