[0002] In real life, with the continuous development and progress of science and technology, mobile phones are developing faster and faster, the production technology of mobile phones is getting better and better, and the production and processing efficiency of the various components collected is also getting faster and faster.

[0003] The mobile phone middle frame is one of the main parts of the mobile phone. It is set between the mobile phone screen and the back cover, and is used to fix the battery, motherboard, camera, cable, microphone and other parts inside the mobile phone. At present, the domestic mobile phone middle frame manufacturing industry either uses CNC machine tools to process and shape them one by one, or uses one mold and one cavity to inject and shape them one by one; with the rapid increase in the market shipment of mobile phones, the demand for mobile phone middle frames has also increased significantly. The low efficiency of the existing one-by-one processing operation method has become increasingly prominent, and it is difficult to meet the requirements of the increasingly competitive social market.

[0004] In the utility model with Chinese patent publication number CN216299972U, a rapid prototyping mobile phone middle frame injection mold is proposed. The rapid prototyping mobile phone middle frame injection mold controls the moving frame to move through the No. 2 electric telescopic rod, which is convenient for adjusting the material conveying range and conveying efficiency, and improving the molding efficiency of the parts; the No. 1 servo motor controls the fixed frame and the connecting frame to rotate, thereby improving the flow speed of the material inside the mold in the cavity, and further improving the molding efficiency of the parts; the No. 2 servo motor controls the rotation of the fixed column, and the No. 3 electric telescopic rod controls the plug plate to lift and lower, so as to quickly remove the injection-molded parts inside the fixed frame and the connecting frame, and improve the processing efficiency; the No. 1 electric telescopic rod controls the fixed frame to lift and lower, so as to cooperate with the plug plate to take the injection-molded parts inside the mold, improve the processing efficiency, and facilitate daily cleaning and maintenance of the mold. However, the rapid prototyping mobile phone middle frame injection mold can only form one workpiece at a time, and the processing efficiency is low. Therefore, the utility model proposes a mobile phone middle frame injection mold. Utility Model Content
