DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the application will be described below with reference to the accompanying drawings in the embodiments of the application.

[0023] Please refer to Figures 1-6 The application provides a remote controller shell injection mold, which comprises a lower mold 10 and an upper mold 20 coupled with the lower mold 10. A plurality of ejector pins 30 are slidably arranged on the top of the lower mold 10. The bottom of the plurality of ejector pins 30 is connected with a same lifting plate 40. The two end sidewalls of the lifting plate 40 are both connected with a locking rod 50. The positioning block 60 capable of being inserted into the upper mold 20 is slidably arranged on the locking rod 50. A plurality of molding cavities 110 are arranged on the top of the lower mold 10. The plurality of ejector pins 30 are slidably arranged in the plurality of molding cavities 110. Specifically, the top of the ejector pin 30 can be accommodated into the bottom of the molding cavity 110, and the top of the ejector pin 30 is flush with the bottom of the molding cavity 110. After the mold is opened, the ejector pin 30 can lift the shell in the molding cavity 110 upward, so that the shell can be taken out. Further, the bottom of the lower mold 10 is connected with a mold base 120.

[0024] Please refer to Figure 2 and 3The lifting template 40 comprises a lifting plate 410, a plurality of ejector pins 30 are arranged in connection with the lifting plate 410, and the locking rod 50 is arranged in connection with the side wall of the lifting plate 410. The lifting template 40 further comprises a lifting rod 420, the lifting rod 420 is arranged to slide through the top of the lower mold 10, and the bottom of the lifting rod 420 is arranged in connection with the lifting plate 410. A spring 430 is arranged to slide on the lifting rod 420, and the two ends of the spring 430 are fixedly connected with the top of the lifting plate 410 and the bottom of the lower mold 10, respectively. When arranged, the lifting rod 420 is used to drive the lifting plate 410 to move downward, that is, when the upper mold 20 and the lower mold 10 are closed, the upper mold 20 will press the lifting rod 420, so that the lifting rod 420 drives the lifting plate 410 to move downward, the top of the lifting rod 420 is accommodated in the top of the lower mold 10, at the same time, the lifting plate 410 stretches the spring 430, and the ejector pins 30 are driven to move downward. When the mold is opened, the spring 430 drives the lifting plate 410 to reset, and the ejector pins 30 move upward.

[0025] Referring to Figure 3 and 5 The lifting plate 410 comprises a connecting plate 4110, the bottom of the connecting plate 4110 is connected with a positioning plate 4120, the lifting rod 420, the ejector pins 30, the locking rod 50 and the spring 430 are arranged in connection with the connecting plate 4110. The connecting plate 4110 is connected with the positioning plate 4120 through the existing screw hole connection structure, at the same time, the lifting rod 420 and the ejector pins 30 are arranged in T shape, so that the lifting rod 420 and the ejector pins 30 slide through the connecting plate 4110, and the heads are arranged at the bottom of the connecting plate 4110, so as to connect the positioning plate 4120 with the bottom of the connecting plate 4110, so as to fix the lifting rod 420 and the ejector pins 30.

[0026] Referring to Figure 1 and 6 The side wall of the upper mold 20 is provided with a positioning hole 210, the positioning block 60 can be inserted into the positioning hole 210, one end of the locking rod 50 is fixedly provided with a limiting rod 510, and the top of the positioning block 60 is fixedly provided with a limiting block 610. The limiting block 610 is arranged to slide on the limiting rod 510. It should be noted that the locking rod 50 is provided with a through hole, and the positioning block 60 is arranged to pass through the through hole. After the upper mold 20 and the lower mold 10 are closed, the positioning block 60 corresponds to the positioning hole 210 on the side wall of the upper mold 20, so as to push the positioning block 60 to be inserted into the positioning hole 210. The end of the limiting rod 510 is connected with a connecting head, so as to prevent the limiting block 610 from falling off from the limiting rod 510.

[0027] The remote controller shell injection mold works as follows: when the upper mold 20 and the lower mold 10 are closed, the upper mold 20 will extrude the lifting rod 420, so that the lifting rod 420 drives the lifting plate 410 to move downward, and the lifting plate 410 drives the plurality of ejector pins 30 to move downward, so that the ejector pins 30 are stored at the bottom of the forming cavity 110, and at the same time, the lifting plate 410 will stretch the spring 430. At this time, the positioning hole 210 on the upper mold 20 corresponds to the positioning block 60 on the locking rod 50, the positioning block 60 is inserted into the positioning hole 210, and the injection molding process can be started. After the shell is cooled and formed, the mold can be opened. First, pull the positioning block 60 out of the positioning hole 210, then separate the upper mold 20 from the lower mold 10, reset the spring 430, drive the lifting plate 410 to move upward, so that the ejector pins 30 move upward and lift the shell, and finally the shell can be taken out.

[0028] It should be noted that the specific model and specifications of the lower mold 10 and the upper mold 20 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method uses existing technology in the art, and therefore will not be described in detail.

[0029] The power supply of the lower mold 10 and the upper mold 20 and its principle are clear to those skilled in the art, and will not be described in detail here.

[0030] The above only describes the embodiments of the present application and is not used to limit the protection scope of the present application. For those skilled in the art, the present application can have various modifications and changes.
