When the earphone shell is stamped and formed, the earphone shell raw materials are first placed in the corresponding flip mold core 62 respectively, and then the single-chip microcomputer 2 starts the electro-hydraulic push rod 3 so that its telescopic end drives the stamping seat 4 to move vertically downward, thereby stamping and forming the earphone shell in the flip mold core 62, and then the single-chip microcomputer 2 controls the electro-hydraulic push rod 3 so that its telescopic end drives the stamping seat 4 to move upward and reset, thereby realizing the stamping and forming operation of the earphone shell;
[0023] The self-discharging mechanism 6 comprises two rotating shafts 61 and overturning mold cores 62. The two rotating shafts 61 are both rotatably connected to the top wall of the mold 5 through bearings 1. The outer side of each rotating shaft 61 is provided with five evenly distributed overturning mold cores 62. Each overturning mold core 62 is located in the overturning groove of the top wall of the mold 5. The self-discharging mechanism 6 further comprises rectangular limiting seats 63, which are respectively arranged at the bottom of the overturning groove and are cooperatively installed with the adjacent overturning mold core 62. The self-discharging mechanism 6 further comprises rotating shafts 64, worms 65, worm gears 66 and hand wheels 69. The worm gears 66 are respectively arranged at the right end of the rotating shafts 61. The top wall of the mold 5 is provided with two symmetrically distributed avoiding grooves. The worm gears 66 are both located in the adjacent avoiding groove. The front and back walls of the mold 5 are both rotatably connected with a worm 65 through a rotating shaft 64. The two worms 65 are fixedly connected. The worm 65 is meshingly connected with the adjacent worm gear 66. The front end of the front rotating shaft 64 is provided with a hand wheel 69. The thread directions of the two worms 65 are opposite. The self-discharging mechanism 6 further comprises annular seats 67 and torsional springs 68. The annular seats 67 are respectively arranged at the end of the rotating shaft 64 away from the center of the mold 5. The outer side of the rotating shaft 64 is sleeved with a torsional spring 68. The front and back annular seats 67 of the mold 5 are fixedly connected with the front end of the adjacent torsional spring 68. The back and front annular seats 67 of the mold 5 are fixedly connected with the back end of the adjacent torsional spring 68. The upper side of the mold 5 is provided with ten evenly distributed overturning limiting columns 7, which are cooperatively installed with the adjacent overturning mold core 62. The front and back sides of the mold 5 are both provided with guide seats 8. The bottom wall of the guide seat 8 is a material sliding slope. The staff rotates the hand wheel 69 to drive the front rotating shaft 64 to rotate. The front rotating shaft 64 drives the two worms 65 to synchronously rotate. Since the thread directions of the two worms 65 are opposite, the front worm 65 is threadedly connected with the corresponding worm gear 66 to drive the front rotating shaft 61 to reverse. The back worm 65 is threadedly connected with the corresponding worm gear 66 to drive the back rotating shaft 61 to rotate forward. In turn, the front overturning mold core 62 is overturned forward around the axis of the corresponding rotating shaft 61, and the back overturning mold core 62 is overturned backward around the axis of the corresponding rotating shaft 61. During the process, one end of the torsional spring 68 rotates synchronously with the annular seat 67 and the rotating shaft 64. The torsional force of the torsional spring 68 increases. When the overturning mold core 62 is overturned to contact the corresponding overturning limiting column 7, since the front overturning mold core 62 is in a moving state, when it suddenly contacts and stops with the overturning limiting column 7, the earphone shell stamped and formed in the overturning mold core 62 separates from the overturning mold core 62 under the action of the overturning moving inertia and falls into the guide seat 8 in a parabolic state, thereby realizing the automatic discharging operation of the earphone shell stamped and formed. The earphone shell in the guide seat 8 slides along the material sliding slope at the bottom to the left end outlet at the bottom for collection. Subsequently, the staff releases the rotating torsional force applied to the hand wheel 69. The overturning mold core 62 is overturned around the axis of the corresponding rotating shaft 61 to reset through the resetting torsional force of the torsional spring 68.The rectangular limiting seat 63 is used for limiting the position of the turnover reset of the turnover mold core 62, and the bottom of the turnover mold core 62 is supported by the rectangular limiting seat 63, so that the pressure bearing capacity of the turnover mold core 62 in the stamping process of the device is increased. The device can automatically take out the stamping formed earphone shell from the forming mold cavity through a transmission element, and manual discharging operation of the stamping formed earphone shell is not required, so that the earphone shell discharging operation is convenient and fast.
[0024] The working principle of the earphone shell forming punch of the utility model is as follows: when the earphone shell is subjected to stamping forming, the earphone shell raw materials are first placed into the corresponding turnover mold core 62, then the single-chip microcomputer 2 starts the electro-hydraulic push rod 3 to drive the stamping seat 4 to move vertically downwards, so that the earphone shell in the turnover mold core 62 is subjected to stamping forming, then the single-chip microcomputer 2 controls the electro-hydraulic push rod 3 to drive the stamping seat 4 to move upwards and reset, then the worker rotates the hand wheel 69 to drive the front shaft two 64 to rotate, the front shaft two 64 drives the two worms 65 to synchronously rotate, since the screw thread directions of the two worms 65 are opposite, the front worm 65 is connected with the corresponding worm wheel 66 through screw threads, so as to drive the front shaft one 61 to reverse, the rear worm 65 is connected with the corresponding worm wheel 66 through screw threads, so as to drive the rear shaft one 61 to rotate forward, so that the front turnover mold core 62 is turned forward around the corresponding shaft one 61, and the rear turnover mold core 62 is turned backward around the corresponding shaft one 61, in this process, one end of the torsional spring 68 rotates synchronously with the annular seat 67 and the shaft two 64, the torsional force of the torsional spring 68 increases, when the turnover mold core 62 contacts the corresponding turnover limiting column 7, since the turnover mold core 62 is in a moving state, when it suddenly contacts and stops the turnover limiting column 7, the earphone shell subjected to stamping forming in the turnover mold core 62 is separated from the turnover mold core 62 under the action of the turnover moving inertia, and falls into the guide seat 8 in a parabolic state, so that the automatic discharging operation of the earphone shell subjected to stamping forming is realized, the earphone shell in the guide seat 8 slides along the bottom material sliding slope to the bottom left end outlet for collection, then the worker releases the rotating torsional force applied to the hand wheel 69, and the turnover mold core 62 is reset around the corresponding shaft one 61 through the reset torsional force of the torsional spring 68, so as to prepare for the discharging of the earphone shell subjected to stamping forming next time, the rectangular limiting seat 63 is used for limiting the position of the turnover reset of the turnover mold core 62, and the bottom of the turnover mold core 62 is supported by the rectangular limiting seat 63, so that the pressure bearing capacity of the turnover mold core 62 in the stamping process of the device is increased.
