[Technical Field]

[0001] This invention relates to the field of mold mechanism technology, and in particular to a threaded slider withdrawal structure. [Background Technology]

[0002] like Figure 1 The product shown has 20 threaded undercuts. Using a conventional mold slider, it is impossible to remove the product structure that has both threads and undercuts, making it impossible to produce this product.

[0003] In view of this, it is necessary to provide a threaded slider withdrawal structure to solve the above problems. [Summary of the Invention]

[0004] The technical problem this invention aims to solve is that when a product has a threaded undercut, a conventional mold slider cannot remove the product structure that has both threads and undercuts, making production impossible. Therefore, this invention provides a threaded slider removal structure to solve the above problem.

[0005] The solution to the technical problem of this invention is: a threaded slider disengagement structure, comprising:

[0006] The female template has a fixed block fixedly connected to its side wall. The fixed block is fixedly connected to a first transmission component at one end that contacts the male template. The female template has a bundle block fixedly connected to the side that contacts the male template. The bundle block is used to cooperate with the inclined groove of the first slider body.

[0007] The male template has a fixed plate on its side wall. A second, third, and fourth transmission component are movably mounted within the fixed plate. The second transmission component rotates via the first transmission component and is mounted on a first rotating shaft. The third transmission component rotates coaxially with the second transmission component and is also mounted on the first rotating shaft. The fourth rotating component rotates via the third transmission component and is mounted on a second rotating shaft. A first bearing and a second bearing are respectively provided at both ends of the first and second rotating shafts to support their axial positions. The male template has a threaded component, a slider body, and a slider insert on the side that contacts the female template.

[0008] A threaded component is fixed in the second rotating shaft at one end away from the product, and the other end passes through the slider body and then through the slider insert. The threaded component conforms to the first structure of the product at the end close to the product. A first elastic element is provided between the first slider body and the second slider body of the threaded component. A limiting block is provided on the side of the first elastic element that contacts the first slider body. The first elastic element is connected to the slider insert on the side that contacts the second slider body, which is used to limit the displacement of the first elastic element.

[0009] The slider body includes a first slider body and a second slider body. A pull rod is provided between the first slider body and the second slider body. One end of the pull rod is movably disposed in the limiting groove of the first slider body, and the other end is fixed in the fixing groove of the second slider body. The pull rod is used to delay the movement of the second slider body, so that the threaded part can be ejected from the product first.

Detailed Implementation Methods

[0020] To further illustrate the technical means and effects of the present invention, the following detailed description is provided in conjunction with the embodiments of the present invention and their accompanying drawings.

[0021] This invention provides a threaded slider disengagement structure, comprising:

[0022] The female template 100 has a fixing block 101 fixedly connected to its side wall. The fixing block 101 is fixedly connected to a first transmission component 103 at one end that contacts the male template 200. The female template 100 is fixedly connected to a bundle block 102 at the other end that contacts the male template 200. The bundle block 102 is used to cooperate with the inclined groove 224 of the first slider body 221, thereby pushing the first slider body 221 to move close to the second slider body 222.

[0023] A template 200 has a fixing plate 104 on its side wall. A second transmission member 201, a third transmission member 202, and a fourth transmission member 203 are movably mounted within the fixing plate 104. The second transmission member 201 rotates in conjunction with the first transmission member 103, and its rotation is mediated by the first transmission member 103. The second transmission member 201 is mounted on a first rotating shaft 204. The third transmission member 202 rotates coaxially with the second transmission member 201 and is also mounted on the first rotating shaft 204. The fourth transmission member 201... 3. Rotational movement is achieved through the third transmission component 202. The fourth rotating component 203 is mounted on the second rotating shaft 205. The first rotating shaft 204 and the second rotating shaft 205 are respectively provided with a first bearing 206 and a second bearing 207 at their ends. The first bearing 206 and the second bearing 207 effectively reduce friction and wear between moving parts, and position and support the axial position of the first bearing 206 and the second bearing 207. The male template 200 has a threaded component 210, a slider body 220, and a slider insert 230 on the side that contacts the female template 100.

[0024] A threaded component 210 is fixed at one end away from the product 300 within the second rotating shaft 205, and the other end passes through the slider body 220 and then through the slider insert 230. The end of the threaded component 210 closest to the product 300 conforms to the first structure 310 of the product 300. A first elastic element 211 is provided between the threaded component 210 and the first slider body 221 and the second slider body 222. A limiting block 212 is provided on the side of the first elastic element 211 that contacts the first slider body 221. The side of the first elastic element 211 that contacts the second slider body 222 is connected to the slider insert 230, which limits the displacement of the first elastic element 211. When the threaded component 210 rotates under the drive of the second rotating shaft 205, the limiting block 212 and the slider insert 230 limit the displacement of the first elastic element 211, allowing the first elastic element 211 to assist the threaded component 210 in exiting the first structure 310 of the product 300.

[0025] The slider body 220 includes a first slider body 221 and a second slider body 222. A pull rod 225 is provided between the first slider body 221 and the second slider body 222. One end of the pull rod 225 is movably disposed in the limiting groove 226 of the first slider body 221, and the other end is fixed in the fixing groove 227 of the second slider body 222. The pull rod 225 is used to delay the movement of the second slider body 222, so that the threaded part 210 can be withdrawn from the product 300 first. A second elastic member 223 is provided at the connection between the first slider body 221 and the second slider body 222. The second elastic member 223 is used to abut against the second slider insert 222 during the movement of the first slider insert 221 to prevent the second slider insert 222 from moving during the opening process. The first slider body 221 is provided with a slanted groove 224, and the slanted groove 224 is connected to the threaded part 210. When the female mold core 100 and the male mold core 200 are molded together, the female mold core 100 drives the fixed bundle 102 to exit the inclined groove 224 of the first slider body 221, thereby causing the bundle 102 to drive the first slider insert 221 to move. At this time, the pull rod 225 moves in the limiting groove 226 of the first slider insert 221, and then the first slider body 221 and the second slider body 222 open a distance. At the same time, the threaded rod 210 exits the first structure 310 of the product 300 under the cooperation of the transmission member 240 and the first elastic member 211. At this time, the first sliding body 221 continues to move under the action of the bundle 102, so that it drives the second slider body 222 to move through the pull rod 225, thereby causing the second slider body 222 to drive the fixed slider insert 230 to exit the second structure 320 of the product 300.

[0026] The slider insert 230 has one end close to the product 300 that conforms to the second structure 320 of the product 300 and is used to form the second structure 320 of the product 300. The other end of the slider insert 230 away from the product 300 is connected to the second slider body 222.

[0027] Preferably, the first transmission member 103 includes, but is not limited to, a rack, and the second transmission member 201, the third transmission member 202 and the fourth transmission member 203 all include, but are not limited to, gears.

[0028] Preferably, both the first elastic element 211 and the second elastic element 223 include, but are not limited to, springs.

[0029] The working process of this invention is as follows: When the mold opens, the female mold core 100 drives the bundle block 102 fixed at one end to move, causing the bundle block 102 to exit the inclined groove 224 on the first slider body 221. With the cooperation of the second elastic member 223, the first slider body 221 moves a certain distance away from the second slider body 222. Simultaneously, the movement of the female mold core 100 drives the first transmission member 103 fixed thereon to move, causing the second transmission member 201 and the third transmission member 202 to rotate coaxially, thereby causing the third transmission member 202 to rotate... The fourth transmission component 203 rotates, causing the threaded component 210 fixed in the second rotating shaft 205 to rotate. At this time, with the cooperation of the first elastic component 211, the threaded component 210 exits the first structure 310 of the product 300. Then, the bundle block 102 continues to move in the inclined groove 224 of the first slider body 221. With the cooperation of the pull rod 225, the first slider body 221 drives the second slider body 222 to move, which in turn causes the second slider body 222 to drive the slider insert 230 fixed on it to exit the second structure 320 of the product 300 until the mold opening is completed.

[0030] The beneficial effects of this invention are that, through a threaded slider withdrawal structure, the first structure 310 and the second structure 320 of product 300 are formed by the cooperation of threaded component 210 and slider insert 230. The threaded component 210 is rotated and withdrawn from the first structure 310 of product 300 by the cooperation of transmission component 240 and first elastic component 211. The slider insert 230 is withdrawn from the second structure 320 of product 300 by the action of the binding block 102 on the side of the female mold core 100 on the slider body 220. Thus, the forming and withdrawal of the first structure 310 and the second structure 320 of product 300 can be realized, which meets the production needs of product 300. This invention can solve the product structure with both threads and undercuts, and it is easy to process, convenient to install, and low in cost.

[0031] It should be noted that the present invention is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made by those skilled in the art to the above embodiments based on the technical solutions of the present invention shall fall within the protection scope of the present invention.
