Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of earphone injection molding, in particular to an earphone core silicone and hardware integral molding mold. Background Art
[0002] As we all know, earphones are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ears. Among the major categories of earphones, wireless earphones have become the mainstream earphones due to their compactness and convenience. Among them, back-hook earphones are one of the product categories of wireless earphones. Compared with conventional earphones, the most different thing is that they are composed of three parts, namely the back-hook part, the main body and the ear-hook part.
[0003] However, for the injection molding of rear-hook earphones, the rear-hook part, the main body and the ear-hook part are generally separately injection-molded and then connected together. Among them, the ear-hook part is used as a connector between the main body and the rear-hook part. Therefore, the structure of the ear-hook part must not only meet the requirements of built-in elastic parts (silicone) but also need to contain hardware for circuit transmission (including wires and hardware plugs). The combination of the two is the earphone core. The earphone core is curved in shape and the structures at both ends are just hardware plugs. There are no other gripping parts. Therefore, the ear-hook part often needs to be injection-molded in batches. First, the outer shell is injection-molded, and then the hardware plug and wire are installed. This requires the elastic part to have an inner tube for wiring. On the other hand, it will cause cumbersome production process, which is not conducive to the rapid completion of product injection molding. It will also consume more human resources. In addition, multiple molds need to be prepared for separate injection molding. Therefore, there are problems that need to be overcome in the injection mold of the rear-hook type.

The top template 1 and the bottom template 2 are provided with injection grooves 7 relative to the receiving port 5 and the limit port 6. The two ends of the injection groove 7 are respectively connected with the receiving port 5 and the limit port 6. After the top template 1 and the bottom template 2 are covered with each other, the injection grooves 7 located on the top template 1 and the bottom template 2 are closed to form an injection cavity. The middle part of the earphone core 100 is suspended in the injection cavity. The top template 1 is provided with injection holes 12 at the corresponding position of each injection groove 7, and the injection holes 12 are connected with the injection groove 7 of the top template 1.
[0024] Based on the design principle of this embodiment, an upper mold core 3 and a lower mold core 4 are directly arranged between the top mold plate 1 and the bottom mold plate 2. The upper mold core 3 and the lower mold core 4 are used to clamp the hardware plugs 101 at both ends of the earphone core 100 after covering, and the part of the earphone core 100 that needs to be injection-molded is suspended in the injection molding cavity, so that the injection molding of the earphone core silicone and hardware of the ear hook part can be completed at one time.
[0025] When performing the injection molding operation, the upper mold core 3 and the lower mold core 4 are installed first, that is, the earphone core 100 is taken first (that is, the elastic member 102, the wire 103, and the hardware plug 101 are connected as a whole), and then the hardware plugs 101 at both ends of the earphone core 100 are respectively placed in the receiving port 5 and the limiting port 6 of the lower mold core 4, and the insertion column 43 provided at one end of the slider 42 is directly inserted into the corresponding hardware plug 101 (the hardware plug 101 connected to the earphone main body will be in the shape of a tube mouth).
