[0002] Headphones are widely used in mobile phones, walkmans, radios, portable video games and digital audio players. The earphone plug that is inserted into the ear cavity is an important part of the earphone. The new UV glue earphone plug uses a silicone material oil pressure molded earplug head, which can make the earphone plug material soft and can better adapt to the needs of different ear shapes, thus making the wearer feel comfortable.

[0003] The new type of UV glue earphone plugs are divided into an inner shell and an outer shell during oil pressure molding.

[0032] The two ends of the rotating block 7 are respectively rotatably inserted into the groove wall of the corresponding first placement groove through a rotating shaft 8; the rotating shafts 8 located on the same side of each row of oil pressure forming stations are commonly connected to a deflection mechanism.

[0033] The deflection mechanism includes a screw rod 10 rotatably inserted in the lower module 1, one end of the screw rod 10 extends through the outside of the lower module 1 and is fixedly connected to an adjustment block 11;

[0034] A toothed bar 12 is sleeved on the surface of the screw rod 10 at the position corresponding to each rotating shaft 8, and a deflection block 13 is meshed and connected to the top of the toothed bar 12. The deflection block 13 is fixedly connected to the end of the rotating shaft 8 away from the rotating block 7;

[0035] A plurality of adjusting blocks 11 are connected to the same external driving mechanism; wherein the rotation directions of the two rotating blocks 7 adjacent to the forming groove 3 are opposite.

[0036] The rotating block 7 is configured as a hollow T-shaped structure, and a contraction mechanism is provided in the inner cavity of the rotating block 7;

[0037] The retracting mechanism includes a moving block 15 and two retracting rods 16 respectively hinged on both sides of the moving block 15, and the ends of the two retracting rods 16 away from the moving block 15 are respectively hinged with a retracting block 17 and an extruding block 18; the retracting block 17 is located on the side of the moving block 15 close to the forming groove 3, and is used to resist the outer shell forming block 5 or the inner shell forming block 6;

[0038] A longitudinal sliding groove is respectively provided on the cavity walls on both sides of the inner cavity near the rotating shaft 8 corresponding to the position of the end of the moving block 15, and the two ends of the moving block 15 are respectively slidably connected to a longitudinal sliding groove; the shrinkage block 17 and the extrusion block 18 are respectively connected to one end of a spring 19 on the opposite sides, and the inner cavity is provided with a shrinkage groove 14 for accommodating the shrinkage block 17 on the side of the moving block 15 near the shrinkage block 17, and another shrinkage groove for accommodating the extrusion block 18 is provided on the side of the moving block 15 near the extrusion block 18, and the other end of the spring 19 is fixedly connected to the groove wall of the shrinkage groove 14.

[0039] The lower module 1 is provided with a limit rod 20 at the top of each column of placement grooves 4, one end of the limit rod 20 is hinged to the pressing surface of the lower module 1, and the other end of the limit rod 20 is provided with a clamping block 21, which is clamped and fixed to the clamping groove opened on the pressing surface of the lower module 1.

[0040] Specifically, the bottom surface of the deflection block 13 is provided with teeth for meshing with the rack bar 12; a plurality of threaded sections are provided at intervals on the screw rod 10, and the threads of two adjacent threaded sections are arranged in opposite directions.

[0041] Specifically, the bottom of the extrusion block 18 is arranged as a slope.

[0042] Specifically, the clamping block 21 is a V-shaped structure.

[0043] Specifically, the center line of the rotating shaft 8 is parallel to the center line of the rotating block 7 , and the center line of the deflection block 13 is parallel to the center line of the rotating shaft 8 .

[0044] When the earphone plug is subjected to hydraulic molding, several groups of rotating blocks 7 are placed in the corresponding placement grooves 4 on the lower module 1, and the outer shell molding block 5 and the inner shell molding block 6 are then placed in the molding groove 3. Since the rotating block 7 is T-shaped, the rotating block 7 is more stable in the placement groove 4. Then the rubber strip can be placed on the top of the same row of molding grooves 3, and then the limit rod 20 is deflected so that the limit rod 20 is clamped and fixed to the lower module 1 through the clamping block 21. The limit rod 20 limits the rotating shaft 8, and then the upper module 2 falls and fits tightly with the lower module 1. The outer shell and the inner shell of the earphone plug are hydraulically molded at one time. After the upper module 2 leaves, the deflection mechanism causes a group of two rotating blocks 7 to rotate in the opposite direction. At the same time, the contraction mechanism contracts the outer shell molding block 5 and the inner shell molding block 6 in a small range, and the earphone plug is demolded.

[0045] The present invention is provided with two rotating blocks 7. After the earphone plug is hydraulically formed, the deflection mechanism drives the two rotating blocks 7 to deflect, so that the outer shell and the inner shell of the earphone plug are deformed and fall off, and there is no need to remove them manually, which effectively avoids the operator's hands from being burned by high temperature. At the same time, there is no need to take out the outer shell forming block 5 and the inner shell forming block 6, thereby improving the production efficiency of the earphone plug.

[0046] After the earphone plug is formed by oil pressure, the external pushing mechanism pushes the several screw rods 10 through the several adjusting blocks 11 to make them rotate repeatedly. Since the screw rods 10 are located between the two toothed bars 12 and the threads are set in reverse, the two toothed bars 12 move in opposite directions and drive the deflection block 13 to rotate. The rotating shaft 8 then drives the rotating block 7 to rotate. At the same time, the limit rod 20 limits the rotating shaft 8, and the deflection mechanism can drive the rotating block 7 to rotate normally.

[0047] The present invention is provided with a deflection mechanism, which converts the external power into the reverse rotation of the two rotating blocks 7, so that the outer shell and the inner shell of the earphone plug are stretched and deformed. Since the material of the earphone plug is elastic, the earphone plug can slowly fall off from the surface of the outer shell forming block 5 and the inner shell forming block 6.

[0048] When the rotating block 7 rotates, since the bottom of the extrusion block 18 is set as a slope, the placement groove 4 squeezes the extrusion block 18 to make it shrink into the shrinkage groove 14. The movement of the extrusion block 18 drives the shrinkage block 17 on one side to move and causes the moving block 15 to move downward. The movement of the moving block 15 drives the shrinkage block 17 on the other side to move, and the shrinkage block 17 shrinks into the shrinkage groove 14 accordingly. The two shrinkage blocks 17 can drive the corresponding outer shell forming block 5 and inner shell forming block 6 to move. In this process, the two springs 19 are compressed and deformed.

[0049] The present invention is provided with a retracting mechanism, which can drive the outer shell forming block 5 and the inner shell forming block 6 to shrink in a small range, so that the tightly attached inner shell and outer shell of the earphone plug are pushed in a small range, thereby effectively accelerating the detachment speed of the earphone plug and improving the production efficiency of the earphone plug.
