In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0044] Please refer to the following: Figures 1 to 9 The injection mold 100 for a mobile phone camera housing provided in this application embodiment will now be described. The injection mold 100 for the mobile phone camera housing includes a lower mold base 10 and an upper mold base 20.

[0045] The lower mold base 10 is provided with a lower mold core 11 at the top, and the upper mold base 20 is provided with a lower mold core 11 at the bottom; when the upper mold base 20 and the lower mold base 10 are closed, the upper mold core 21 and the lower mold core 11 can form a molding cavity for injection molding of the mobile phone camera housing 200. The lower mold core 11 is provided with a first mounting through hole 111, which penetrates the upper and lower surfaces of the lower mold core 11. A first molding insert 112 that can move up and down is provided in the first mounting through hole 111. The lower mold base 10 is provided with a first top plate 12 that can move up and down. A first top post 121 is provided at the top of the first top plate 12 and extends upward. A first elastic element 13 is provided between the bottom of the first molding insert 112 and the first top post 121. When the upper mold base 20 and the lower mold base 10 are closed, the upper mold core 21 can cause the first molding insert 112 to move downward. When the upper mold base 20 and the lower mold base 10 are opened, the first elastic element 13 can provide an elastic force for the elastic insert to eject the mobile phone camera housing.

[0046] Specifically, by providing a first elastic element 13 between the first molding insert 112 and the first ejector pin 121, the first elastic element 13 provides an upward elastic force to the first molding insert 112. After the upper mold base 20 and the lower mold base 10 open, the first elastic element 13 first provides an elastic force to the first molding insert 112, so that the first molding insert 112 provides part of the force to the mobile phone camera housing, reducing the adhesion between the mobile phone camera housing and the lower mold core 11. This makes it easier for the mobile phone camera housing to be ejected from the mold when the first ejector pin 121 moves the first molding insert 112 upward to eject the mobile phone camera housing. This reduces the possibility of product deformation or damage during demolding, thereby improving demolding efficiency and product yield.

[0047] In some embodiments, the upper surface of the lower mold core 11 is provided with a lower molding cavity 1101, and the lower surface of the upper mold core 21 is provided with an upper molding cavity 2101. When the upper mold base 20 and the lower mold base 10 are closed, the lower molding cavity 1101 and the upper molding cavity 2101 can form a molding chamber for injection molding a mobile phone camera housing. The upper mold base 20 is provided with a glue injection port 22, which is connected to the upper molding cavity 2101 through a glue injection channel. When injection molding a mobile phone camera housing, the upper mold base 20 and the lower mold base 10 are installed on an injection molding machine. The injection molding machine drives the upper mold base 20 to move and complete the mold closing or opening with the lower mold base 10. After the upper mold base 20 and the lower mold base 10 are closed, hot melt slurry is injected into the glue injection port 22 through the injection molding machine. The hot melt slurry flows into the molding chamber through the glue injection channel. After the hot melt slurry in the molding chamber cools down, the mobile phone camera housing is formed.

[0048] It is understandable that by setting multiple lower forming cavities 1101 in the lower mold core 11 and multiple upper forming cavities 2101 in the upper mold core 21, multiple mobile phone camera housings can be injection molded simultaneously in one injection mold. This is a conventional design method for those skilled in the art, and will not be described in detail here.

[0049] Specifically, the top of the first molding insert 112 can extend upward into the molding cavity or retract downward into the first mounting through hole 111; the bottom of the first molding insert 112 is recessed upward with a first mounting notch 1121, the first top post 121 extends upward into the first mounting notch 1121, and the top of the first top post 121 is spaced apart from the top surface of the first mounting notch 1121; one end of the first elastic member 13 abuts against the top surface of the first mounting notch 1121, and the other end abuts against the top of the first top post 121.

[0050] For example, after the upper mold base 20 and the lower mold base 10 are closed, the upper mold core 21 can act on the first molding insert 112 to move down by 0.5 cm; then, after the hot melt slurry is injected into the molding cavity and the mobile phone camera shell is solidified, the upper mold base 20 opens relative to the lower mold base 10; at this time, the first molding insert 112 is provided with an upward elastic force by the first elastic member 13, so that the camera will not be completely adhered to the lower molding cavity 1101; after the first top plate 12 moves upward, the first top post 121 can continue to act on the first molding insert 112 to move upward, and finally push the mobile phone camera shell out from the lower molding cavity to complete the unloading. During the process of the first top post 121 moving upward to eject the first molding insert 112, the first elastic element 13 can provide buffering, thereby ensuring that the ejection of the first top post 121 and the first molding insert 112 is smoother and will not cause jamming, further improving the smoothness of ejection of the mobile phone camera housing and the production yield.

[0051] In other embodiments, the lower mold core 11 is provided with a second mounting through hole 113, which penetrates the upper and lower surfaces of the lower mold core 11. The second mounting through hole 113 is provided with a second molding insert 114 that can move up and down. The top of the first top plate 12 is provided with a second top post 122 that extends upward. A second elastic element 14 is provided between the second molding insert 114 and the second top post 122. The lower mold core 11 is provided with a third mounting through hole 115, which penetrates the upper and lower surfaces of the lower mold core 11. The third mounting through hole 115 is provided with a third molding insert 116 that can move up and down. The top of the first top plate 12 is provided with a third top post 123 that extends upward. A third elastic element 15 is provided between the third molding insert 116 and the third top post 123.

[0052] It is understood that the second molding insert 114 and the third molding insert 116 have roughly the same structure, and the second top post 122 and the third top post 123 have roughly the same structure; the second molding insert 114 and the third molding insert 116 are provided with a first extension 1141 at the bottom of their sides, and the top of the second top post 122 and the top of the third top post 123 are respectively spaced from the bottom of the corresponding first extension 1141; one end of the second elastic member 14 abuts against the bottom of the first extension 1141, and the other end abuts against the top of the second top post 122; one end of the third elastic member 15 abuts against the bottom of the first extension 1141, and the other end abuts against the top of the third top post 123.

[0053] Specifically, the first molding insert 112, the second molding insert 114, and the third molding insert 116 are arranged in a triangular spacing; this structure can provide a balanced force to the mobile phone camera housing, so that the ejection force on the mobile phone camera housing during the ejection and demolding process is more balanced, and the demolding process of the mobile phone camera housing is smoother.

[0054] Preferably, the first elastic element 13, the second elastic element 14, and the third elastic element 15 are either springs or elastic plastics.

[0055] It should be noted that the first top plate 12 is also provided with a conventional ejector pin 124. The conventional ejector pin 124 can be moved upward by the first top plate 12 to abut against the surface of the mobile phone camera housing and push the mobile phone camera housing outward.

[0056] More specifically, the upper mold core 21 is provided with a first abutting protrusion 23, a second abutting protrusion 24 and a third abutting protrusion 25; when the upper mold base 20 and the lower mold base 10 are closed, the first abutting protrusion 23 can abut against the first molding insert 112 and cause the first molding insert 112 to move downward; the second abutting protrusion 24 can abut against the second molding insert 114 and cause the second molding insert 114 to move downward; and the third abutting protrusion 25 can abut against the third molding insert 116 and cause the third molding insert 116 to move downward.

[0057] Understandably, after the upper mold base 20 and the lower mold base 10 are closed, the first abutting protrusion 23 causes the first molding insert 112 to move downward, the second abutting protrusion 24 causes the second molding insert 114 to move downward, and the third abutting protrusion 25 causes the third molding insert 116 to move downward. When the mobile phone camera casing is injection molded and formed, the upper mold base 20 and the lower mold base 10 are opened. The first abutting protrusion 23, the second abutting protrusion 24, and the third abutting protrusion 25 will cancel their force on the corresponding first molding insert 112, second molding insert 114, and third molding insert 116, allowing the first elastic element 13 to provide an elastic force on the first molding insert 112, the second... The elastic element 14 provides a force to the second molding insert 114, and the third elastic element 15 provides a force to the third molding insert 116. The first molding insert 112, the second molding insert 114, and the third molding insert 116 first exert elastic force to push out the mobile phone camera housing, allowing the mobile phone camera housing to detach from the lower molding cavity 1101, and balancing the pushing force of the first molding insert 112, the second molding insert 114, and the third molding insert 116. Finally, the first top plate 12 simultaneously moves the first molding insert 112, the second molding insert 114, and the third molding insert 116 upwards, pushing out the mobile phone camera housing for unloading.

[0058] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
