[0029] Example

[0030] like Figure 1 The child lock housing 60 shown has a cavity 601 in the middle and a square hole 6011 on one side of the cavity 601. The housing 60 is provided with a mounting part 602, which is provided with a mounting hole 6021 and a positioning post 6022.

[0031] Reference Figure 2-7 As shown, this utility model discloses a molding die for a child lock housing 60, including a panel 10, an upper moving mold 20, a lower fixed mold 30, an ejector plate 40, and a base 50 from top to bottom. The upper moving mold 20 is fitted with an upper mold core 201, and the lower fixed mold 30 is fitted with a lower mold core 301. The upper mold core 201 has two molding grooves 2011, and the lower mold core 301 has two molding blocks 3011. During injection molding, the upper mold core 201 and the lower mold core 301 close, and the molding grooves 2011 cover the molding blocks 3011, which are used to mold the main body of the housing 60. The molding blocks 3011 are used to mold the cavity 601 of the housing 60. Furthermore, the molding blocks 3011 have several molding slits, and ribs are provided inside the cavity 601 of the housing 60.

[0032] Reference Figure 6-7 As shown, the lower mold core 301 has slots 3012 on both sides of the molding block 3011, and the upper mold core 201 covers the slots 3012 for molding the housing 60 mounting part 602. A first side slider 302 is provided on the lower fixed mold 30, and a first molding rod 3021 is mounted on the first side slider 302. A first guide rod is provided at the bottom of the upper moving mold 20, and a first guide hole is provided on the first side slider 302, with the first guide rod placed in the first guide hole. Specifically, during mold closing and injection molding, the first side slider 302 pushes the first guide rod to extend into the slots 3012, and the mold closing and injection molding forms the mounting holes 6021 on both sides of the mounting part 602.

[0033] Reference Figure 3-5As shown, a guide groove 2012 communicating with the outside is opened on one side of the molding groove 2011. A second side slider 202 is provided on the upper moving mold 20, and a second molding rod 2021 is installed on the second side slider 202. The second side slider 202 has a second guide hole. A second guide rod 101 is provided at the bottom of the panel 10. The second guide rod 101 slidably passes through the upper moving mold 20 and is placed in the second guide hole. During mold closing and injection molding, the second guide rod 101 drives the second molding rod 2021 to extend into the molding groove 2011 and abut against the molding block 3011 for molding the square hole 6011 on the side wall of the cavity 601 of the housing 60.

[0034] Reference Figure 6-7 As shown, a protrusion is provided in the molding groove 2011, and a groove is opened in the molding block 3011. During injection molding, the protrusion is placed in the groove to form the recessed part on the surface of the housing 60. Furthermore, several positioning grooves 3013 are opened at the bottom of the plate groove 3012. The positioning grooves 3013 are used to form the positioning post 6022 of the mounting part 602.

[0035] In addition, several ejector pins are provided on the ejector plate 40. The ejector pins slide upward through the lower fixed mold 30 to the plate slot 3012. When the mold is opened, the upper mold core 201 and the lower mold core 301 separate. The first forming rod 3021 leaves the upper mold core 201, and the second forming rod 2021 leaves the lower mold core 301. The ejector plate 40 pushes the ejector pins upward to push the housing 60 out of the forming block 3011, thereby realizing demolding.

[0036] 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.
