Description

Technical Field

[0001] This utility model relates to the field of locking structure technology, and in particular to an automatic locking structure that can quickly change molds. Background Technology

[0002] Currently, patent number CN202223304105.5 discloses an automatic locking structure for mold processing, which includes an upper mold. The upper mold is slidably connected to a lower mold via four sliding rods. A fixing plate is provided on the side of the lower mold, and a sleeve is fixedly connected inside the fixing plate. Four locking blocks are provided on the lower surface of the inner wall of the sleeve, and the four locking blocks are locked to the same chuck. This automatic locking structure for mold processing, by setting up a sleeve, chuck, elastic tightening plate, balancing plate, elastic shrinking cylinder, and extrusion cylinder, can lock the upper and lower molds during mold processing, thereby preventing the upper and lower molds from shaking during processing and affecting their processing accuracy. Furthermore, after the mold processing is completed, the automatic locking structure can quickly separate the upper and lower molds, making it convenient for workers to inspect and clean them.

[0003] The above-mentioned patent has been found to have the following problems in actual use: the distance of the locking structure is difficult to adjust, and after changing to other molds, it may be difficult to lock due to the size problem of the locking part, which affects the overall work efficiency and locking quality.

[0004] Therefore, we propose an automatic locking structure that enables rapid mold changing. Utility Model Content

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0026] See Figures 1-4 This utility model provides an automatic locking structure for quick mold changing, including a base 1 and a base 2. An insert rod 3 is provided between the base 1 and the base 2. The base 1 and the base 2 are set at the bottom of the mold and the position between the base 1 and the base 2 is adjusted according to the width of the mold. A sleeve 6 is connected to the middle of the base 1 and the base 2. A connecting rod 8 is fixedly installed on the sleeve 6. A locking hook 12 is movably provided on one side of the top of the connecting rod 8. A fine adjustment component is provided at the top of the connecting rod 8. The fine adjustment component is connected to the tail end of the locking hook 12. A reinforcing plate 7 is connected to the side wall of the connecting rod 8.

[0027] The fine-tuning component includes a side plate 9, which is fixedly installed on the top wall of the connecting rod 8. An electric cylinder 10 is fixedly connected to the inner side of the side plate 9, and the output end of the electric cylinder 10 corresponds to the tail end of the locking hook 12.

[0028] The output end of the electric cylinder 10 is connected to the push rod 11. The end of the push rod 11 is fixedly connected to the tail end of the locking hook 12. Two auxiliary rods are connected to the bottom end of one side of the locking hook 12. The two auxiliary rods are embedded inside the connecting rod 8.

[0029] A motor 4 is fixedly connected to one side of the middle part of the base 2. A rotating rod 17 is fixedly connected to the output end of the motor 4. A telescopic rod 16 is fixedly connected to the end of the rotating rod 17. The middle parts of the rotating rod 17 and the telescopic rod 16 are respectively connected to the sleeve 6.

[0030] The telescopic rod 16 extends and retracts as the base 1 and base 2 move. The inner wall of the telescopic rod 16 is pre-sealed with a sealing strip. The motor 4 drives the two sets of locking hooks 12 to rotate synchronously. Since the position between the base 1 and base 2 can be adjusted, the telescopic rod 16 is provided so as not to affect the rotation of the two locking hooks 12.

[0031] By setting up base 1 and base 2, both base 1 and base 2 are connected with flip-up locking hooks 12. The position between base 1 and base 2 can be adaptively adjusted according to the diameter of the mold, so that the locking hooks 12 can be accurately aligned with the locking part, thereby ensuring the locking effect after changing the mold and improving production quality and efficiency.

[0032] By connecting an electric cylinder 10 to the top of the connecting rod 8, the electric cylinder 10 can drive the locking hook 12 to make fine adjustments to the lateral distance, thereby adjusting for different molds and different locking positions and improving the locking quality.

[0033] One end of the insertion rod 3 is fixedly connected to the limiting plate 5. The inner side wall of the limiting plate 5 is pre-set with a damping strip, and several through holes 13 are opened on the insertion rod 3.

[0034] A positioning plate 14 is connected to one side of the edge of the base 2. A positioning pin 15 is connected to the positioning plate 14. The size of the positioning pin 15 is adapted to the size of the through hole 13. After adjusting the position between the base 1 and the base 2, the positioning pin 15 is embedded in the through hole 13 to form a limit. At this time, the base 1 and the base 2 are fixed in place so as to facilitate the locking operation later.
