Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone shell production molds, in particular to a mobile phone shell production mold which is easy to split. Background Art

[0002] The mobile phone shell production mold that is easy to part is a mold specially designed for manufacturing mobile phone shells. It has a specific structure and function to ensure that the finished product can be easily separated during the production process, thereby improving production efficiency and ensuring the quality of the finished product. The mold is usually composed of an upper mold and a lower mold, which can be moved and separated relatively independently. This design makes it easy to take out the finished product during parting. Some parts in the mold, such as side molds, sliders, etc., are usually designed to be movable. The movement of these parts can be controlled by hydraulic, pneumatic and other systems to achieve automated parting operations. The mobile phone shell production mold that is easy to part is very important in the mobile phone manufacturing industry. It can help manufacturers reduce production costs, improve production efficiency, and at the same time ensure the quality and consistency of mobile phone shells.

[0003] After searching, the publication number CN218948345U discloses a mold for producing a mobile phone shell that is easy to demould, including a lower mold, a mounting frame is installed on the left side of the lower mold, and a hydraulic cylinder is installed on the upper right side of the mounting frame, and the output end of the hydraulic cylinder is connected to the upper mold, and the upper mold and the lower mold are engaged with each other; and also includes: a feed channel, which is opened inside the upper mold, and a fixed rod is connected to the outer side of the upper end of the upper mold, and a connecting rod is installed below the other end of the fixed rod. The mold for producing a mobile phone shell that is easy to demould is provided with an adjustment side frame and a push rod. When the upper mold moves up, the fixed plate can be driven to move up, and the transmission of the connecting rod and the adjustment rod can be used to drive the moving rod to drive the adjustment side frame to move in a direction away from the fixed mold, so as to release the restriction of the adjustment side frame on the edge of the mobile phone shell, so as to facilitate the demoulding of the mobile phone shell. At this time, with the upward movement of the push rod, the mobile phone shell can be pushed to be demoulded quickly and conveniently, without the need for manual auxiliary demoulding.

[0004] However, the above patents still have some shortcomings. For example, in the actual use of the mobile phone shell production mold that is easy to split, it is necessary to realize the alternation of demolding and injection molding, which helps to make the production process more continuous and efficient, and improves the stability and consistency of production. The above technology is only convenient for demolding the mobile phone shell. At this time, with the upward movement of the ejector rod, the mobile phone shell can be demolded quickly and conveniently without manual auxiliary demolding, but it is impossible to achieve the effect of alternating demolding and injection molding, which helps to make the production process more continuous and efficient, and improves the stability and consistency of production.

[0029] Specifically, the rotation of the first rotating rod 2 drives the first rotating block 3 to rotate. When the outer wall of the first rotating block 3 is in contact with the upper surface of the limiting column 5 fixedly connected to the upper surface of the second fixed plate 4, the first rotating rod 2 rotates in the opposite direction. The first fixed plate 1 here fixes the second fixed plate 4, and the second fixed plate 4 fixes the limiting column 5. The limiting column 5 limits the first rotating block 3.

[0031] Specifically, the telescopic motor 13 fixedly connected to the outer wall of the first fixed plate 1 is started, and the first fixed plate 1 here plays a fixing role on the telescopic motor 13. The telescopic motor 13 is started to drive the telescopic rod 14 to telescope, and the telescopic rod 14 drives the rack 16 to slide along the upper surface of the limit bar 15. The rack 16 here plays a telescopic role on the telescopic rod 14, and the telescopic rod 14 has a pulling effect on the rack 16. The first fixed plate 1 plays a fixing role on the limit bar 15, and the limit bar 15 plays a limiting sliding role on the telescopic rod 14. The rack 16 moves to drive the gear 17 meshing with it to rotate, thereby prompting the first rotating rod 2 to rotate on the inner wall of the first fixed plate 1. The first fixed plate 1 here plays a fixing role on the first rotating rod 2.

[0032] Reference Figure 5 - Figure 6 The lower surface of the first fixed plate 1 is fixedly connected with an injection molding plate 18, and the outer wall of the injection molding plate 18 is fixedly connected with a mold base 19; the outer wall of the mold base 19 is fixedly connected with an outer box 20, and a servo motor 21 is arranged inside the outer box 20; the output end of the servo motor 21 is fixedly connected with a third rotating rod 22, and the outer wall of the third rotating rod 22 is rotatably connected to the inside of the injection molding plate 18; the outer wall of the third rotating rod 22 is fixedly connected with a round block 23, and the lower surface of the injection molding plate 18 is fixedly connected with a sliding cylinder 24;

The rack 16 moves and drives the gear 17 meshing with it to rotate, thereby causing the first rotating rod 2 to rotate on the inner wall of the first fixed plate 1. The first rotating rod 2 rotates and drives the first rotating block 3 to rotate. When the outer wall of the first rotating block 3 is in contact with the upper surface of the limit column 5 fixedly connected to the upper surface of the second fixed plate 4, the first rotating rod 2 rotates in the opposite direction. The rotation of the first rotating block 3 drives the rotation inside the first rotating block 3, causing the second rotating block 7 to slide along the first sliding groove 11 opened on the outer wall of the sliding block 10, and also drives the sliding block 10 to slide along the outer wall of the sliding bar 9, causing the second rotating block 7 to drive the upper mold cover 8 to swing the arm, thereby achieving the alternate demoulding and injection molding, which helps to make the production process more continuous and efficient. The servo motor 21 inside the outer box 20 fixedly connected to the outer wall of the mold base 19 is started, and the servo motor 21 is started to drive the third rotating rod 22 to rotate inside the injection plate 18. The rotation of the third rotating rod 22 drives the round block 23 to rotate. The rotation of the round block 23 drives the sliding wheel 27 to rotate along the outer wall of the fixed rod 26, thereby driving the mold separation rod 25 to slide up and down along the inside of the sliding cylinder 24. When the injection molding of the upper surface of the injection molding plate 18 is completed, the mold separation rod 25 is forced to slide completely through the inside of the injection molding plate 18, so that it is easier and faster to remove the finished product from the mold, thereby reducing the production cycle, increasing production capacity and improving production efficiency. The device can not only achieve the effect of alternating demoulding and injection molding, thereby helping the production process to be more continuous and efficient and improving the stability and consistency of production, but also can achieve the effect of easier and faster removal of the finished product from the mold, thereby reducing the production cycle, increasing production capacity and improving production efficiency.
