Detailed implementation manners

[0020] To further elaborate on the technical means and effects adopted by the present invention, the following describes it in detail in combination with the embodiments of the present invention and their accompanying drawings.

[0021] The present invention provides a threaded slider withdrawal structure, including:

[0022] A female template 100, a fixed block 101 is fixedly connected to the side wall of the female template 100, a first transmission part 103 is fixedly connected to one end of the fixed block 101 in contact with the male template 200, a beam block 102 is fixedly connected to the side of the female template 100 in contact with the male template 200, and the beam block 102 is used to cooperate with the inclined groove 224 of the first slider body 221, so as to push the first slider body 221 to move to be close to the second slider body 222;

[0023] A male template 200, a fixing plate 104 is provided on the side wall of the male template 200, a second transmission part 201, a third transmission part 202 and a fourth transmission part 203 are movably arranged in the fixing plate 104, the second transmission part 201 rotates by cooperating with the first transmission part 103, the second transmission part 201 makes a rotational movement through the first transmission part 103, the second transmission part 201 is arranged on the first rotating shaft 204, the third transmission part 202 rotates coaxially with the second transmission part 201, the third transmission part 202 is arranged on the first rotating shaft 204, the fourth rotating part 203 makes a rotational movement through the third transmission part 202, the fourth rotating part 203 is arranged on the second rotating shaft 205, first bearings 206 and second bearings 207 are respectively arranged at both ends of the first rotating shaft 204 and the second rotating shaft 205, and the first bearings 206 and the second bearings 207 can effectively reduce the friction and loss between moving parts, as well as position and support the axial positions of the first bearings 206 and the second bearings 207. A threaded part 210, a slider body 220 and a slider insert 230 are provided on the side of the male template 200 in contact with the female template 100; among them,

[0024] A threaded member 210, one end of the threaded member 210 away from the product 300 is fixed within the second rotating shaft 205, and the other end passes through the slider body 220 and then through the slider insert 230. One end of the threaded member 210 near the product 300 is shaped to conform to the first structure 310 of the product 300. A first elastic member 211 is provided at the position where the threaded member 210 passes between the first slider body 221 and the second slider body 222. A limiting block 212 is provided on one side of the first elastic member 211 in contact with the first slider body 221. One side of the first elastic member 211 in contact with the second slider body 222 is connected to the slider insert 230, which is used to limit the displacement of the first elastic member 211. When the threaded member 210 rotates driven by the second rotating shaft 205, the displacement of the first elastic member 211 is limited by the limiting block 212 and the slider insert 230, so that the first elastic member 211 assists the threaded member 210 to withdraw from the first structure 310 of the product 300;

[0025] A slider body 220, 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 arranged 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 member 210 can withdraw 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 press 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. An inclined groove 224 is provided on the first slider body 221, and the inclined groove 224 cooperates with the beam block 102. When the female mold core 100 and the male mold core 200 are separated, the female mold core 100 drives the beam block 102 fixed thereon to withdraw from the inclined groove 224 of the first slider body 221, and then the beam block 102 drives 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. Then, the first slider body 221 and the second slider body 222 are separated by a certain distance first. At the same time, after the threaded rod 210 withdraws from 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 beam block 102, so that it drives the second slider body 222 to move through the pull rod 225, and then the second slider body 222 drives the slider insert 230 fixed thereon to withdraw from the second structure 320 of the product 300;

[0026] The slider insert 230, one end of the slider insert 230 close to the product 300 is shaped to conform to the second structure 320 of the product 300, which is used to form the second structure 320 of the product 300, and the 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, the first elastic member 211 and the second elastic member 223 both include but are not limited to springs.

[0029] The working process of the present invention is as follows: When the mold is opened, the female mold core 100 drives the beam block 102 fixed at one end thereof to move, so that the beam block 102 exits the inclined groove 224 on the first slider body 221, and under the cooperation of the second elastic member 223, the first slider body 221 moves a certain distance toward the end away from the second slider body 222. At the same time, when the female mold core 100 moves, it drives the first transmission member 103 fixed thereon to move, so that the second transmission member 201 cooperating with it and the third transmission member 202 rotate coaxially, and further makes the fourth transmission member 203 cooperating with the third transmission member 202 rotate. In this way, the threaded member 210 fixed in the second rotating shaft 205 rotates. At this time, under the cooperation of the first elastic member 211, the threaded member 210 exits the first structure 310 of the product 300. Then the beam block 102 continues to move in the inclined groove 224 of the first slider body 221, and under the cooperation of the pull rod 225, the first slider body 221 drives the second slider body 222 to move, and further makes the second slider body 222 drive the slider insert 230 fixed thereon to exit the second structure 320 of the product 300 until the mold opening is completed.

[0030] The beneficial effect of the present invention is that through a threaded slider withdrawal structure, the present invention uses the threaded member 210 and the slider insert 230 to cooperate to form the first structure 310 and the second structure 320 of the product 300. The transmission member 240 cooperates with the first elastic member 211 to make the threaded member 210 rotate and exit the first structure 310 of the product 300, and through the beam block 102 on the side of the female mold core 100 acting on the slider body 220 to drive the slider insert 230 to exit the second structure 320 of the product 300. Thus, the formation and withdrawal of the first structure 310 and the second structure 320 of the product 300 can be realized, meeting the production of the product 300. This invention mechanism can solve the product structure with both threads and undercuts, and it is easy to process, convenient to install, and has a low cost.

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