DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 to Figure 4 In an embodiment of the utility model, a servo punching mechanism of a feeder includes a sleeve 1, the inner wall of the sleeve 1 is slidably connected to a telescopic rod 2, the bottom end of the telescopic rod 2 is detachably connected to an upper mold 3 through a connecting assembly, a lower mold 5 is placed below the upper mold 3, and a cavity 6 is provided inside the upper mold 3 and the lower mold 5, a compensation spring 4 is provided between the top of the upper mold 3 and the bottom of the telescopic rod 2; the connecting assembly is used to quickly connect the top end of the upper mold 3 with the bottom end of the telescopic rod 2; an unlocking and separating assembly is provided inside the connecting assembly on the upper mold 3, and the unlocking and separating assembly is used to conveniently separate the upper mold 3 from the telescopic rod 2.

[0022] In this embodiment: the top of the sleeve 1 is connected to the output end of the servo hydraulic cylinder. The molten glass is first inverted in the molding cavity 6 of the lower mold 5. Then, by starting the servo hydraulic cylinder, the output end of the servo hydraulic cylinder drives the sleeve 1 to move downward until the bottom end of the upper mold 3 contacts the bottom end of the lower mold 5. At this time, the upper mold 3 remains stationary, and the servo hydraulic cylinder continues to push the sleeve 1 downward. At this time, the sleeve 1 slides along the outer wall of the telescopic rod 2 and squeezes the compensation spring 4, so as to apply sufficient downward pressure to the upper mold 3 and shape the molten glass in the molding cavity 6.

[0023] Due to changes in orders, the shape and surface pattern of the produced glass need to be changed accordingly. At this time, the upper mold 3 can be removed and replaced with a new one by unlocking the separation component to release the limit of the connection component on the upper mold 3.

[0024] Please refer to Figure 2 and Figure 3The connecting components are distributed inside the telescopic rod 2 and the top of the upper mold 3. The connecting components include a plug-in column 7. A receiving groove for accommodating the plug-in column 7 is opened at the bottom end of the telescopic rod 2. The plug-in column 7 is fixedly connected to the top of the upper mold 3. The connecting components also include two strip grooves 11 opened inside the telescopic rod 2, and the two strip grooves 11 are symmetrically arranged. The inner wall of the strip groove 11 is slidably connected to the limit plate 13, and the inner wall of the strip groove 11 is provided with a connecting spring 12. One end of the connecting spring 12 is fixedly connected to one end of the limit plate 13 located inside the strip groove 11, and the other end of the connecting spring 12 is fixedly connected to the inner wall end of the strip groove 11. A connecting groove 8 for engaging with the limit plate 13 is opened inside the plug-in column 7.

[0025] In this embodiment: the plug-in column 7 is inserted into the receiving groove. When the top of the plug-in column 7 contacts the compressed inclined surface of the limit plate 13, the limit plate 13 is forced to move toward the inside of the strip groove 11 and squeeze the connecting spring 12 until the limit plate 13 completely enters the strip groove 11. When the plug-in column 7 is fully inserted into the receiving groove, the plug-in column 7 drives the connecting groove 8 to be aligned with the limit plate 13 in the horizontal direction. At this time, the connecting spring 12 is reset, and the connecting spring 12 pushes the limit plate 13 to be stuck in the connecting groove 8. Since the top surface of the limit plate 13 is flat, the limit plate 13 limits the plug-in column 7 in the receiving groove, thereby completing the fixation of the upper mold 3.

[0026] Please refer to Figure 1 and Figure 2 The unlocking and separation assembly includes an extrusion plate 9 which is slidably connected to the inner wall of the connecting groove 8 up and down. A return spring 10 is fixedly connected to the top of the extrusion plate 9. The top of the return spring 10 is fixedly connected to the top of the inner wall of the connecting groove 8. The bottom end of the limit plate 13 located outside the strip groove 11 is formed with a pressure inclined surface. Extrusion inclined surfaces are formed at both ends of the extrusion plate 9. The pressure inclined surfaces are consistent with the extrusion inclined surfaces. A force-bearing rod 14 is connected to the center of the bottom end of the extrusion plate 9. The bottom end of the force-bearing rod 14 passes through the upper wall of the cavity 6 of the upper mold 3 and is flush with the upper wall of the cavity 6.

[0027] In this embodiment: when the upper mold 3 needs to be replaced, the lower mold 5 is first removed from the supporting surface 15 (the supporting surface 15 is a fixed platform of the device) and moved away, and then a push rod that matches the size of the force-bearing rod 14 is placed under the force-bearing rod 14, and a groove 16 for placing the push rod can be opened on the supporting surface 15, so that no cumbersome calibration is required. When the servo hydraulic cylinder drives the sleeve 1 to descend, the sleeve 1 drives the upper mold 3 to move downward through the telescopic rod 2 until the force-bearing rod 14 contacts the push rod. At this time, the upper mold 3 continues to move downward until the bottom end of the upper mold 3 contacts the supporting surface 15. In this process, the force-bearing rod 14 remains stationary, that is, the extrusion plate 9 remains stationary, and the limit plate 13 moves downward. At this time, the extrusion inclined surface of the extrusion plate 9 squeezes the pressure inclined surface of the limit plate 13, and squeezes the limit plate 13 into the inner cavity of the strip groove 11 again, completing the separation of the connecting groove 8 and the limit plate 13. At this time, by rotating the upper mold 3, the upper mold 3 drives the plug-in column 7 and the force-bearing rod 14 (columnar) to rotate, so as to realize the horizontal misalignment of the connecting groove 8 and the limit plate 13. Later, when the servo hydraulic cylinder drives the sleeve 1 to rise, the limit plate 13 cannot be aligned with the connecting groove 8, so that the upper mold 3 can be replaced.

[0028] Please refer to Figure 3 The number of the return springs 10 is multiple, and the multiple return springs 10 are evenly distributed along the axial direction.

[0029] In this embodiment, a plurality of return springs 10 press the extrusion plate 9 to the lowest position, so as to avoid the situation that the extrusion plate 9 cannot be smoothly returned to its original position after being moved.

[0030] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
