[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Referring to the accompanying drawings: This USB data cable precision injection mold for an automatic injection molding assembly line includes a front mold frame bottom plate 1, a front mold frame 2, a rear mold frame 3, an ejector fixing plate 4, and a rear mold frame bottom plate 5. The rear mold frame 3 has an installation cavity 31 for arranging a rear mold core 6. A front mold core that cooperates with the rear mold core is arranged in the front mold frame. The installation cavity 31 is provided on the rear mold frame 3 with a flow channel 31-a for guiding the passage of the clamp 7. The rear mold core 6 has a soft plastic injection positioning block 61 and a hard plastic injection positioning block 62. The soft plastic injection positioning block 61 and the hard plastic injection positioning block 62 both have There is a front positioning station 63 for placing some USB male plugs and USB female plugs, and a rear positioning station 64 for placing some USB wires. The flow channel 31-a has a left opening 31-a1 located on the left side and serving as an inlet end, and a right opening 31-a2 located on the right side and serving as an outlet end on the rear mold frame 3. The clamp 7 enters the flow channel 31-a from the left opening 31-a1 and leaves the flow channel 31-a from the right opening 31-a2, and is used to clamp the USB male plug and USB female plug exposed outside the front positioning station 63. The principle of the utility model is that the front end of the assembly line has two vibration disks, one vibration disk is equipped with a USB plug, and the other vibration disk is equipped with a wire. The USB plug flows through the assembly line to the pneumatic control device for assembly and connection, and then flows into the fixture for positioning and fixing. Then the fixture 7 and the wire enter from the flow channel 31-a, and pass through the soft glue injection positioning block 61 and the hard glue injection positioning block 62. The soft glue injection positioning block 61 performs soft glue injection, and the hard glue injection positioning block 62 performs hard glue injection. After the injection is completely completed, the fixture 7 flows out from the right opening 31-a2, and the plug component of the USB data line is removed from the fixture 7 by disassembling the pneumatic device and then the first step of the cycle is restarted. Through this structural setting, fully automatic production is achieved, production efficiency is improved, and cost is reduced. In this embodiment, the configurations of the front mold core and the rear mold core are adapted.

[0022] The soft-glue injection molding positioning block 61 and the hard-glue injection molding positioning block 62 have the same configuration, and are both set to be block-shaped components with a step configuration, and the low-step surfaces of both are kept at the same level with the bottom surface of the flow channel 31-a, and a guide channel 65 is formed between the left opening 31-a1 and the right opening 31-a2 through the intermediate connecting surface between the low-step surface and the high-step surface and the inner side surface of the installation cavity 31. The clamp 7 is placed in the guide channel 65 when clamping the USB male plug and the USB female plug. The soft-glue injection molding positioning block 61 and the hard-glue injection molding positioning block 62 have the same configuration, which reduces the difficulty of production, and the only difference between the two is the width dimension of the front positioning station 63 for setting the USB male and female plugs, because the U When the SB male and female end plugs are placed in the front positioning station 63 in the hard glue injection molding positioning block 62, the first step of soft glue injection molding has been completed. The volume will increase after the soft glue injection molding, so the width dimension of the front positioning station 63 of the soft glue injection molding positioning block 61 is smaller than the width dimension of the front positioning station 63 of the hard glue injection molding positioning block 62. At the same time, the step configuration setting can obtain a guide channel 65 that is interconnected with the flow channel 31-a, so that the clamp can enter the guide channel 65 by moving after entering the rear flow channel 31-a through the left opening 31-a1, and also through the guide channel 65 to bring the USB data cable to the soft glue injection molding positioning block 61 and the hard glue injection molding positioning block 62, thereby completing the soft glue injection molding and hard glue injection molding.

[0023] A pad block 8 is commonly provided in the flow channel 31-a and the guide channel 65. The pad block 8 extends along the length direction of the flow channel 31-a or the guide channel 65 and is supported under the clamp 7. The pad block 8 is used to fill the gap between the soft-glue injection molding positioning block 61 and the flow channel 31-a, and the hard-glue injection molding positioning block 62 and the flow channel 31-a, thereby obtaining a plane that makes the movement of the clamp 7 smoother.

[0024] There are two clamps 7, including an upper clamp 71 and a lower clamp 72. The upper clamp 71 is arranged at the bottom of the front mold frame 2, and the lower clamp 72 is arranged in the guide channel 65. Both of them have a clamping station 73 for placing some USB male plugs and USB female plugs. The setting of the two clamps 7 can simultaneously meet the soft glue and hard glue injection molding, thereby improving production efficiency. The upper clamp 71 and the lower clamp 72 are used to meet the needs of clamping USB male and female plugs.

[0025] The lower clamp 72 is provided with two positioning holes 72-a which are arranged opposite to each other, and the upper clamp 71 is provided with a positioning rod 71-a which is combined with the positioning hole 72-a. The combination of the positioning hole 72-a and the positioning rod 71-a enables the lower clamp 72 and the upper clamp 71 to be completely assembled together when combined, and no offset will occur between the two clamps, thereby ensuring that the USB male and female plugs can be stably clamped in the clamp 7.

[0026] The clamping station 73 on the upper clamp 71 and the clamping station 73 on the lower clamp 72 are both provided with a locking socket 74 located at the front end of the clamping station 73 and passing through the upper clamp 71 and the lower clamp 72. A locking plug 74-a arranged on the front mold frame 2 is inserted into the locking socket 74. The locking plug 74-a is inserted into the locking socket 74. The purpose is to tightly press the USB male and female plugs in the clamping station 73. This can also prevent the USB male and female plugs from shaking in the clamping station 73, thereby improving the injection molding quality during soft plastic injection molding and hard plastic injection molding.

[0027] The mounting cavity 31 is provided with a plurality of slots 31-b arranged along the length direction of the rear mold frame 3 on the rear mold frame 3. The slots 31-b extend along the height direction of the rear mold frame 3 and are provided with plug posts 9 partially exposed outside the slots 31-b. The exposed part of the plug posts 9 is provided with guide blocks 91 perpendicular to the extension direction of the plug posts 9. The lower clamp 72 and the guide blocks 91 are relatively arranged at a position with guide grooves 72-b for the guide blocks 91 to slide in. The guide grooves 72-b extend along the length direction of the lower clamp 72. The slots 31-b are used to set the plug posts 9, and the plug posts 9 and the slots 31-b have an interference fit, so that the plug posts 9 are stably placed in the slots 31-b, so that the guide blocks 91 are stably maintained in a fixed position. In this way, after the clamp 7 passes, the guide blocks 91 can stably enter the guide grooves 72-b. The combination of the guide grooves 72-b and the guide blocks 91 can increase the stability of the movement of the clamp 7 in the guide channel 65 to avoid floating of the clamp 7 during movement.

[0028] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
