Detailed Description
As shown in fig. 3 and 4, the utility model relates to a thread-twisting slider mold structure, which comprises a slider mechanism 1 and a thread-twisting mechanism 2.
As shown in fig. 4 and 5, the slide mechanism 1 includes a platen 11, a slide insert 12, a slide holder 13, and a shovel base 14. The upper end of the shovel base 14 is fixed on the fixed die plate 3, the lower end of the shovel base 14 is inserted into the guide groove 131 of the slider seat 13, the inner end of the slider seat 13 is fixedly connected with the outer end of the slider insert 12, the inner end of the slider insert 12 extends to the die cavity, the slider seat 13 is connected in a sliding way formed by the pressing plate 11 and the movable die plate through a slot block matching mode, and the pressing plate 11 is fixed on the movable die plate 4.
As shown in fig. 3 and 6, the thread twisting mechanism 2 includes an oil cylinder support 21, an oil cylinder 22, a rack 23, a large gear 24, a small gear 25, a core 26 (shown in fig. 7), a slider seat 27, an oil cylinder connecting sleeve 28, a stroke limiting column 29, and a stroke switch 210; the cylinder body of the oil cylinder 22 is fixed on the side wall of the movable template through an oil cylinder support member 21, the piston rod end of the oil cylinder 22 is connected with the outer end of a rack 23 through an oil cylinder connecting sleeve 28 and a slider seat 27, the inner end of the rack 23 is meshed with a large gear 24, the large gear 24 is rotatably installed in the movable template and is meshed with a small gear 25, the small gear 25 is fixedly sleeved in the middle of a core 26, and the upper end of the core 26 extends into a cavity and is used for forming threads of a product; the travel switch 210 is mounted on the cylinder support 21 and located on the moving track of the slider seat 27, and the travel limit post 29 is mounted on the cylinder support 21 and abuts against the slider seat 27 to limit the travel of the slider seat 27.
The utility model discloses a theory of operation:
as shown in fig. 3 and 4, before opening the mold, the oil cylinder 22 in the tooth twisting mechanism 2 acts to drive the large gear 24 to rotate along with the pulling of the rack 23, so as to drive the small gear 25 to rotate and further drive the core 26 to rotate, and the stroke is calculated, that is, the stroke of the rack 23 at least needs to be enough for the number of rotating shafts of the core 26, so that the core 26 is completely separated from the internal teeth 101 (as shown in fig. 2) of the product 10; the mold is opened, the shovel base 14 drives the slider seat 13 to move outwards, so that the slider insert 12 is driven to move outwards, after the mold is completely opened, the slider insert 12 is completely separated from the reverse buckle (shown in figure 1) of the product 10, and finally, the product is ejected out again, and automatically drops, so far, the whole cycle is completed.
The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
