[0009] Preferably, the opening and closing mechanism includes a connecting rod, the number of baffles is 2, the baffles are provided with cylindrical slide rods, the connecting rod has a sliding groove at both ends, the two slide rods are slidably connected with the sliding grooves, the two baffles are slidably connected with the guide rail, the distance between the two baffles is equal to the diameter of the ferrule blank, the connecting rod is rotatably connected with the rack by a torsional spring, the connecting rod is connected with a push rod, and the push rod abuts against the feeding disc.

[0010] By extruding the push rod with the feeding disc, the connecting rod is rotated to drive one baffle to stop blocking the ferrule blank, and the other baffle blocks the subsequent ferrule blank, so that the ferrule blank can be dropped one by one when the feeding disc moves to the guide rail, and multiple ferrule blanks to be processed can be placed on the guide rail, and multiple ferrule blanks can be placed without causing two or more ferrule blanks to fall at the same time, and by blocking with the baffles, the ferrule blank can be placed one by one without falling from a high place to obtain a large inertia, which can cause the ferrule blank to separate from the feeding disc due to inertia, affecting the cold extrusion of asymmetric ferrule blank.

[0012] Through the setting of the swing rail, when the swing rail swings under the elastic force of the torsion spring, the opening of the swing rail can swing to the mold cavity of the mold, thereby avoiding scratches on the extruded ferrule blank when the ferrule blank is pushed out by the ejection mechanism, and avoiding the ferrule blank from falling from a high place and jumping to affect the normal operation of the synchronous control device.

[0013] Preferably, two clamping rods are symmetrically installed on the feeding disc and are provided with clamping blocks, and a push rod is slidably installed on the feeding disc and is provided with a Y-shaped structure, one side of the push rod abuts against the two clamping rods, and the other side of the push rod abuts against the swing rail, and the side of the clamping rod in contact with the push rod is provided with a flexible block.

When the diameter of the socket is equal to the diameter of the ferrule blank, the rotation of the feeding disc will interfere with the ferrule blank after the ferrule blank is pushed into the mold cavity by the extrusion mechanism, and thus cannot rotate, so it is necessary to ensure that the diameter of the socket is greater than the diameter of the ferrule blank, so that the ferrule blank can more easily enter the socket, and the positioning arc surface provided on the push rod can position the ferrule blank, thereby avoiding the ferrule blank from failing to enter the mold cavity and causing a processing accident, and the circular arc surface provided on the clamping block can make the pushing force of the clamping block on the ferrule blank towards the center of the positioning arc surface, thereby avoiding the ferrule blank from rolling on the positioning arc surface due to uneven force, causing the ferrule blank to fail to align with the mold cavity, and thus causing the ferrule blank to fail to enter the mold cavity and causing a processing accident.

[0019] Preferably, the clamping block is hingedly connected with the clamping rod, and the hinged part has a hinged gap.

[0020] The hinged connection of the clamping block and the clamping rod and the hinged gap at the hinged part can adjust the angle and position of the clamping block when the clamping block contacts the ferrule blank, so that the circular arc surface is completely attached to the ferrule blank, the clamping force of the clamping block on the ferrule blank is prevented from deviating and pushing the ferrule blank to move on the positioning arc surface, and the coaxiality of the ferrule blank and the mold cavity is affected.

[0025] 2、Through the elastic connection of the swing rail on the rack, the opening of the swing rail can be swung to the mold cavity of the mold, so as to avoid scratches caused by the ferrule blank falling from a high place when the ferrule blank is extruded by the ejection mechanism, and to avoid the ferrule blank jumping when falling from a high place and affecting the normal operation of the synchronous control device, and when the feeding disc extrudes the swing rail, the swing rail can be away from the mold, without interfering with the pressing operation.
