[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] This embodiment refers to Figures 1 to 8A blister forming device for a blister packaging machine comprises a box body 1, a top plate 2 and a forming mold 5, wherein the forming mold 5 comprises an upper mold bottom plate 51, an upper mold 52, a lower mold 53, a lower mold bottom plate 54 and a cooling plate 55, wherein the upper mold 52 is mounted at the bottom of the upper mold bottom plate 51, and the cooling plate 55 is arranged between the lower mold 53 and the lower mold bottom plate 54, and the top plate 2 is connected to the box body 1 through a column 3, and a first cylinder 4 is arranged on the top of the top plate 2, and the first cylinder 4 is used to drive the upper mold bottom plate 51 to move up and down; a driving mechanism 8 is arranged in the box body 1, and the driving mechanism 8 is movably connected with a lower mold push rod shaft 14 fixed on the lower end surface of the lower mold bottom plate 54 through a pin shaft 13, and is used to drive the lower mold 53 to move up and down; the lower mold bottom plate 54 and the lower mold 52 are locked by a locking mechanism 12, and the locking mechanism 12 comprises a pull rod 12 2. The pull rod 122 is slidably arranged in the lower mold push rod shaft 14. One end of the pull rod 122 is fixedly connected to the tension block 9, and the other end is fixedly connected to the second cylinder 121 through the connecting rod 123. The second cylinder 121 is fixedly installed on the lower part of the lower mold push rod shaft 14 through the cylinder mounting plate 124. The lower end surface of the lower mold 53 is provided with a T-slot 11. The flange portion 901 of the tension block 9 is in contact with the locking surface 1101 of the T-slot 11. The cooling plate 55 is provided with a lower mold guide rail 10 adapted to the T-slot 11. The T-slot 11 is slidably matched with the lower mold guide rail 10. The T-slot 11 and the lower mold guide rail 10 are both arranged along the length direction of the molding mold 5. In order to ensure that the tension block 9 and the pull rod 122 can move freely, the lower mold guide rail 10 is divided into two sections, which are respectively located on both sides of the tension block 9.

[0023] Through the above arrangement, the lower mold 53 is pushed onto the cooling plate 55 along the lower mold guide rail 10, and the second cylinder 121 is started to pull the tensioning block 9 downward, so that the lower mold 53 can be conveniently locked on the cooling plate 55, and then locked on the lower mold base plate 54 together with the cooling plate 55. The clamping mechanism 12 does not require the use of bolts for manual clamping, which reduces the labor intensity of the staff, improves the reliability of clamping and improves the efficiency of mold changing.

[0024] Preferably, the molding die 5 is located in the space formed between the box body 1 and the top plate 2 , and a guide mechanism 6 is provided on the box body 1 .

[0025] Preferably, the guide mechanism 6 includes a sliding bearing 62 fixed on the box body 1 and a lower mold guide column 61 slidably assembled in the sliding bearing 62, and the top end of the lower mold guide column 61 is fixedly connected to the lower mold bottom plate 54.

[0026] Through the above arrangement, it is ensured that the molding mold 5 will not produce mold position deviation during the mold opening and closing process, the mold matching accuracy is guaranteed, and the quality of blister molding is improved.

[0027] Preferably, the driving mechanism 8 includes an eccentric wheel 81 and a spline shaft 82 that drives the eccentric wheel 81 to rotate. The swing arm 8101 arranged outside the eccentric wheel 81 is movably connected to the lower end of the lower mold push rod shaft 14 through the pin shaft 13. The rotation of the spline shaft 82 drives the eccentric wheel 81 to rotate, thereby realizing the up and down movement of the lower mold base plate 54, thereby realizing the opening and closing of the molding mold 5.

[0028] Preferably, a long slot hole 1401 for accommodating the connecting rod 123 is provided on the lower mold push rod shaft 14, and the length of the long slot hole 1401 is greater than the stroke of the tension block 9. The above arrangement ensures the reliability of the tension block 9 when locking and releasing.

[0029] Preferably, a handle 15 is provided on the same side of the upper mold 52 and the lower mold 53, and the pulling direction of the handle 15 is parallel to the lower mold guide rail 10. A limiting baffle 7 is provided on the side of the lower mold base plate 54 away from and facing the handle 15. Through the above arrangement, it is convenient and labor-saving to replace the upper mold 52 and the lower mold 53, and the positioning is accurate. Through the action of the limiting baffle 7, the upper mold 52 and the lower mold 53 achieve a quick positioning effect of one push into place, thereby improving the mold changing efficiency.

[0030] When the lower mold 53 on the molding mold 5 needs to be replaced, the piston rod of the second cylinder 121 extends out, and the pull rod 122 moves upward under the action of the connecting rod 123 to relieve the pressure applied to the lower mold 53. The staff can directly pull out the lower mold 53 through the handle 15, and through the positioning of the lower mold guide rail 10, the staff directly pushes the new lower mold 52 onto the cooling plate 55. When the lower mold 53 is pushed to the limit baffle 7, the second cylinder 121 starts to work, and the piston rod retracts, driving the pull rod 122 to move downward, and the lower mold 53 and the cooling plate 55 are tightened by the tightening block 9, and then pressed on the lower mold bottom plate 54 to achieve mold locking; the lower end face of the lower mold 53 is provided with a T-slot 11, and the cooling plate 55 is provided with a lower mold guide rail 10 adapted to the T-slot 11. The lower mold 53 is positioned when the mold is changed, and there is no need to readjust the mold later, which saves time and effort and reduces the production cost of the enterprise.

[0031] The above embodiments are used to further illustrate the present invention, but the present invention is not limited to these specific embodiments. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be understood to be within the protection scope of the present invention.
