[0001] This utility model belongs to the field of integrated stamping technology, specifically an integrated stamping mold for the lower cover of a display screen back shell. Background Technology

[0002] An integrated stamping die is a mold that uses stamping equipment to form metal sheets in one go, directly producing the required parts or products. Through the direct stamping of the upper and lower die bases, an integrated punch and die can be formed, ensuring structural stability.

[0003] In the current technology, the existing integrated stamping mold for the lower cover of the display back shell usually adopts a design of separate upper and lower molds, and uses the upper and lower molds to combine and stamp at the same time. It also has appropriate grooves and protrusions, and the workpiece can be formed as a whole after stamping with an electric push rod.

[0004] Existing integrated stamping dies have issues where the height of the die may not match the user's height due to individual differences. This causes significant inconvenience when pouring molten iron. Therefore, to address this problem, an integrated stamping die for the lower cover of a display screen is proposed.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-4This utility model provides an integrated stamping mold for the lower cover of a display screen, including a mold auxiliary base 1; a servo motor 2 is mounted on the side of the mold auxiliary base 1; a mirror screw 15 is fixedly connected to the output end of the servo motor 2; the inner wall of the mirror screw 15 is rotatably connected to the inner wall of the mold auxiliary base 1; a movable block 16 is threadedly connected to the outer wall of the mirror screw 15; the movable block 16 is slidably connected to the inner wall of the mold auxiliary base 1; a lifting block 14 is slidably connected to the inner wall of the mold auxiliary base 1; a support rod 17 is rotatably connected to the lifting block 14 through the movable block 16; a mold fixing plate 3 is fixedly connected to the top of the lifting block 14; a bottom mold block 11 is fixedly connected to the top of the mold fixing plate 3; the bottom mold... The top of block 11 has a mold groove 18. During operation, before the mold is filled, the servo motor 2 can be started first. At this time, the mirror screw 15 with a mirror thread along the middle position will rotate. At the same time, because the movable block 16 is threaded to the outer wall of the mirror screw 15, and the bottom of the movable block 16 is slidably connected to the inner bottom wall of the mold auxiliary base 1, the rotation of the mirror screw 15 can drive the movable blocks 16 to move closer to each other. During the process of the movable blocks 16 moving closer to each other, the support rod 17 will also rotate synchronously. At this time, the support rod 17 will lift the lifting block 14, thereby achieving the purpose of controlling the height of the mold fixing plate 3, so that the height of the bottom mold block 11 can be adjusted according to the user's height.

[0027] Furthermore, such as Figure 1 , Figure 3 and Figure 4As shown, a mounting bracket 7 is fixedly connected to the top of the mold fixing plate 3; a transverse electric push rod 8 is installed on the inner wall of the mounting bracket 7; two sets of transverse electric push rods 8 are provided; a first sealing plate 9 is fixedly connected to the output end of the transverse electric push rod 8; a first mold block 10 is fixedly connected to the side of the first sealing plate 9; a first mold hole rod 22 is fixedly connected to the side of the first mold block 10; a second sealing plate 19 is fixedly connected to the output end of the transverse electric push rod 8; a second mold block 20 is fixedly connected to the side of the second sealing plate 19; a second mold hole rod 21 is fixedly connected to the side of the second mold block 20; a demolding electric push rod 13 is installed on the inner wall of the lifting block 14; a demolding module 12 is fixedly connected to the output end of the demolding electric push rod 13; the demolding module 12 is slidably connected to the bottom mold block 11; a support frame 4 is fixedly connected to the top of the mold fixing plate 3; a stamping electric push rod 5 is installed on the top of the support frame 4; a top mold plate 6 is fixedly connected to the output end of the stamping electric push rod 5; the top mold plate 6 and the bottom mold block 11 are positioned opposite each other. During operation, after activating the transverse electric push rod 8, the first mold block 10 and the second mold block 20 can be fitted into the interior of the bottom mold block 11. Then, after activating the demolding electric push rod 13, the demolding module 12 descends and becomes parallel to the inner bottom wall of the bottom mold block 11. Molten iron is then poured into the mold groove 18. Subsequently, the stamping electric push rod 5 is activated to stamp the top mold plate 6. After stamping, the transverse electric push rod 8 can be retracted, causing the second mold hole rod 21 and the first mold hole rod 22 to separate from the workpiece. At this time, the workpiece is no longer limited by the mold. Then, the demolding electric push rod 13 can be activated to lift the workpiece with the demolding module 12, which facilitates the demolding of the workpiece.

[0028] Working principle: Before the mold is filled, the servo motor 2 can be started first. At this time, the mirror screw 15, which has a mirrored thread along the middle position, will rotate. At the same time, because the movable block 16 is threaded to the outer wall of the mirror screw 15, and the bottom of the movable block 16 is slidably connected to the inner bottom wall of the mold auxiliary base 1, the rotation of the mirror screw 15 can drive the movable blocks 16 to move closer together. During the process of the movable blocks 16 moving closer together, the support rod 17 will also rotate synchronously. At this time, the support rod 17 will lift the lifting block 14, thereby achieving the purpose of controlling the height of the mold fixing plate 3, so that the height of the bottom mold block 11 can be adjusted according to the user's height. After the transverse electric push rod 8 is activated, the first mold block 10 and the second mold block 20 can be attached to the inside of the bottom mold block 11. Then, after the demolding electric push rod 13 is activated, the demolding module 12 is lowered and parallel to the inner bottom wall of the bottom mold block 11. Then, molten iron is poured into the mold groove 18. Then, the stamping electric push rod 5 is activated to stamp the top mold plate 6. After the stamping is completed, the transverse electric push rod 8 can be retracted to separate the second mold hole rod 21 and the first mold hole rod 22 from the workpiece. At this time, the workpiece is no longer limited by the mold. Then, the demolding electric push rod 13 can be activated to lift the workpiece with the demolding module 12, which facilitates the demolding of the workpiece.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
