[0032] Example

[0033] Reference Figure 3-5 As shown, this utility model discloses a T-shaped lower cover 70 forming mold, including a panel 10, a pad 20, an upper moving mold 30, a lower fixed mold 40, an ejector plate 50, and a base plate 60 from top to bottom. The upper moving mold 30 has a semi-circular upper mold core 301 embedded at its bottom, and the bottom of the upper mold core 301 has an arc-shaped groove 3011. The lower fixed mold 40 has a lower mold core 401 embedded in it, and the lower mold core 401 has a semi-circular groove 402. An arc-shaped protrusion 4021 is provided in the semi-circular groove 402. A second side forming block 403 is slidably provided on both sides of the semi-circular groove 402. Specifically, during mold closing, the upper moving mold 30 drives the upper mold core 301 to close with the lower mold core 401 of the lower fixed mold 40, and the arc-shaped groove 3011 and the arc-shaped protrusion 4021 close to form the cavity of the main body of the T-shaped lower cover 70; the second side sliders on both sides move to both sides of the semi-circular groove 402 to form the grooves on the outer sides of both ends of the T-shaped lower cover 70 and the first mounting post 701 in the groove.

[0034] Reference Figure 6 , Figure 9 As shown, first side forming blocks 302 are slidably arranged on both sides of the upper mold core 301. Specifically, guide rods 201 that can move up and down are arranged on both sides inside the upper mold core 301. The upper end of the guide rod 201 is connected to the pad 20, and the lower end of the guide rod 201 has a T-shaped first protrusion. The first side forming blocks 302 have an inclined first T-shaped groove on the side facing the guide rod 201. When the mold is closed, the pad 20 presses down on the upper moving mold 30, and the guide rod 201 moves downward to push the first protrusion towards both sides of the upper mold core 301 to form the grooves on the inner sides of both ends of the T-shaped lower cover 70 and the first mounting post 701 in the groove. When the mold is opened, the pad 20 separates from the upper moving mold 30, and the guide rod 201 drives the first side forming blocks 302 to exit from the grooves on the inner sides of both ends of the T-shaped lower cover 70. Furthermore, the sides of the pad 20 and the upper moving mold 30 are connected by a fastening mechanism. When the mold is opened, the pad 20 moves upward first, which first drives the first side forming block 302 to be dislodged from the groove of the T-shaped lower cover 70, and then drives the upper moving mold 30 to move upward to separate the upper mold core 301 and the lower mold core 401.

[0035] Reference Figure 7-8 As shown, a slidable third side forming block 404 is provided at the bottom of the semi-circular groove 402. A guide block 4042 is provided inside the lower fixed mold 40. The guide block 4042 has a second T-shaped groove. A T-shaped second protrusion is provided at the bottom of the third side forming block 404. A hydraulic cylinder 4041 is provided on the side of the lower fixed mold 40. The hydraulic cylinder 4041 is connected to the guide block 4042. The hydraulic cylinder 4041 drives the guide block 4042 to move horizontally. The cooperation between the second T-shaped groove and the second protrusion drives the third side forming block 404 to extend into or out of the bottom of the semi-circular groove 402, which is used to form the extension 702 in the middle of the T-shaped lower cover 70 and the second mounting post 7021.

[0036] In addition, several push blocks are provided at the bottom of the semi-circular groove 402. The push blocks are inclined downward and can slide through the lower fixed mold 40 and the pad plate 20 to connect to the ejector plate 50. Specifically, when the mold is opened, the second side forming block 403 exits from the outside of the T-shaped lower cover 70, the ejector plate 50 pushes the push blocks upward, and the push blocks push the T-shaped lower cover 70 to disengage from the lower mold core 401, thereby realizing the demolding of the T-shaped lower cover 70.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
