[0002] A mobile phone receiver usually consists of the following main parts: Receiver unit: The receiver unit is the part of the mobile phone used to receive sound, usually including one or more speakers and related coils, magnets and other components. The sound is converted into sound waves by the receiver unit for the user to hear. Receiver grid: The receiver grid is usually located at the top of the mobile phone, used to cover the receiver unit, protect the internal components from the intrusion of dust, dirt and other substances, and play an aesthetic role. Wires and connectors: Wires and connectors are used to connect the receiver unit to the motherboard of the mobile phone to transmit sound signals. They are usually composed of flexible circuit boards or cables to ensure stable signal transmission. These components together constitute the function and structure of the mobile phone receiver:

[0003] After the parts are die-cast, since the parts are in a high temperature state and softened state, some of them will adhere to the die-casting table during the demolding process, making it impossible for some parts to fall off. Therefore, a die-casting mold structure for mobile phone earpiece parts is urgently needed.
