[0007] The upper mold fixing assembly includes a tie rod bolt and an upper mold fixing plate disposed inside the frame. The upper mold fixing plate has a first through hole that penetrates vertically, and the frame has a second through hole that corresponds to the first through hole. The tie rod bolt includes a small rod portion and a large rod portion that are coaxially arranged. The upper end of the large rod portion movably protrudes through the second through hole, and the lower end face of the large rod portion abuts against the upper end face of the upper mold fixing plate. The small rod portion is movably installed in the first through hole and protrudes from the first through hole. The lower end of the small rod portion that protrudes from the first through hole is provided with a threaded section for connecting the target upper mold, so that the target upper mold and the upper mold fixing plate can be detachably connected.

[0008] The lower mold fixing assembly includes a lower mold fixing plate that is spaced apart from the upper mold fixing plate, and a lower mold base plate located between the lower mold fixing plate and the upper mold fixing plate. The lower mold base plate is detachably connected to the lower mold fixing plate. The side of the lower mold base plate facing away from the lower mold fixing plate is used to connect to the target lower mold. A notch is formed on the frame for the lower mold base plate to enter and exit.

[0009] Optionally, the lower mold fixing assembly further includes a T-shaped guide block vertically disposed on the lower mold fixing plate and a locking bolt connecting the T-shaped guide block and the lower mold fixing plate, the locking bolt being perpendicular to the lower mold fixing plate;

[0010] The lower mold base plate is provided with a T-shaped groove corresponding to the T-shaped guide block. The lower mold base plate is used to slide and connect to the lower mold fixing plate through the T-shaped groove and the T-shaped guide block.

[0011] Optionally, the lower mold fixing assembly further includes a T-shaped guide bar connected to the lower mold fixing plate and adapted to the T-slot;

[0012] The T-shaped guide bar is connected to one side of the T-shaped guide block and extends in the same direction as the T-shaped guide block.

[0013] Optionally, a handle is provided on the lower mold base plate.

[0014] Optionally, at least two guide pillars are vertically fixedly installed on the lower mold base plate, the target lower mold is sleeved on the guide pillars and the lower end face of the target lower mold abuts against the lower mold base plate, and the target upper mold is provided with a guide sleeve corresponding to the guide pillars.

[0034] Please refer to the following: Figures 1 to 7This application now describes a blister forming device with a convenient mold assembly and disassembly. This blister forming device includes a frame 100, an upper mold fixing assembly, and a lower mold fixing assembly. The frame 100 typically consists of a base plate, side plates, and a top plate. Wherein:

[0035] The upper mold fixing assembly includes a tie rod bolt 201 and an upper mold fixing plate 202 disposed inside the frame 100. The upper mold fixing plate 202 has a vertically penetrating first through hole 203, and the frame 100 has a second through hole 204 corresponding to the first through hole 203. The tie rod bolt 201 includes a small rod portion 2011 and a large rod portion 2012 coaxially arranged; the upper end of the large rod portion 2012 movably protrudes through the second through hole 204, and the lower end face of the large rod portion 2012 abuts against the upper end face of the upper mold fixing plate 202. The rod 2011 is movably installed in the first through hole 203 and extends out of the first through hole 203. The lower end of the rod 2011 extending out of the first through hole 203 is provided with a threaded section for connecting the target upper mold 401, so that the target upper mold 401 is detachably connected to the upper mold fixing plate 202. In this embodiment, the second through hole 204 is provided on the top plate constituting the frame 100. The tie rod bolt 201 is screwed into the threaded hole corresponding to the target upper mold 401 through the threaded section to pull the target upper mold 401 tight onto the upper mold fixing plate 202. Here, the second through hole 204 is usually larger than the first through hole 203. The corresponding tie rod bolt 201 is a stepped shaft structure as described above. The diameter of the large rod part 2012 shaft body accommodated in the second through hole 204 is larger than the diameter of the small rod part 2011 shaft body accommodated in the first through hole 203. In this way, when the tie rod bolt 201 is tightened with the corresponding threaded hole on the target upper mold 401, the target upper mold 401 can be pulled tight onto the upper mold fixing plate 202 because the end face at the step abuts against the upper mold fixing plate 202.

[0036] The lower mold fixing assembly includes a lower mold fixing plate 301 that is spaced apart from the upper mold fixing plate 202, and a lower mold base plate 302 located between the lower mold fixing plate 301 and the upper mold fixing plate 202. The lower mold base plate 302 is detachably connected to the lower mold fixing plate 301. The side of the lower mold base plate 302 facing away from the lower mold fixing plate 301 is used to connect the target lower mold 402. A notch 101 is formed on the frame 100 for the lower mold base plate 302 to enter and exit.

[0037] According to the structure provided in this embodiment, the blister forming apparatus provided in this embodiment includes an upper mold fixing assembly and a lower mold fixing assembly. The target upper mold 401 can be connected to a tie rod bolt 201 movably installed in the first through hole 203 and the second through hole 204. The target lower mold 402 can be installed on the lower mold base plate 302 and connected to the lower mold fixing plate 301 via the lower mold base plate 302. When mold replacement is required, the target upper mold 401 and target lower mold 402 can be assembled and aligned outside the frame 100 before being sent into the frame 100 through the notch 101 provided on the frame 100. Since the alignment operation can be performed outside the frame 100, it has a convenience far superior to the prior art. In addition, after the target upper mold 401 and the target lower mold 402 are sent into the frame 100, the tie rod bolt 201 can pass through the second through hole 204 and the first through hole 203 from the outside of the frame 100 and fix the upper mold, so that the target upper mold 401 and the target lower mold 402 can be separated from each other to realize the normal operation of blister molding, which significantly reduces the time required to change the mold and is far superior to the existing technology.

[0038] In another embodiment of this application, please refer to Figures 1 to 7 The lower mold fixing assembly also includes a T-shaped guide block 303 vertically disposed on the lower mold fixing plate 301 and a locking bolt 304 connecting the T-shaped guide block 303 and the lower mold fixing plate 301. The locking bolt 304 is perpendicular to the lower mold fixing plate 301. The lower mold base plate 302 is provided with a T-shaped groove 305 corresponding to the T-shaped guide block 303. The lower mold base plate 302 is used to slide and connect to the lower mold fixing plate 301 through the cooperation of the T-shaped groove 305 and the T-shaped guide block 303.

[0039] According to the structure provided in this embodiment, the T-shaped guide block 303 can serve as a guide structure for the lower mold base plate 302, thereby enabling the lower mold base plate 302 to slide more precisely to a predetermined position by sliding relative to the T-shaped guide block 303, thus improving mold changing efficiency. Furthermore, in this embodiment, the T-shaped guide block 303 can move closer to or further away from the lower mold fixing plate 301 under the action of the locking bolt 304. Therefore, the position of the lower mold base plate 302 can be flexibly locked or the lower mold base plate 302 can be easily moved relative to the lower mold fixing plate 301 by the locking bolt 304, providing a flexible and convenient adjustment effect.

[0040] In another embodiment of this application, please refer to Figures 1 to 7The lower mold fixing assembly also includes a T-shaped guide bar 306 connected to the lower mold fixing plate 301 and adapted to the T-shaped groove 305. The T-shaped guide bar 306 is connected to one side of the T-shaped guide block 303 and extends in the same direction as the T-shaped guide block 303. According to the structure provided in this embodiment, the T-shaped guide bar 306 can serve as an extension of the T-shaped guide block 303, further improving the sliding stability of the lower mold base plate 302 relative to the lower mold fixing plate 301, and also without affecting the locking effect of the T-shaped guide block 303 on the lower mold base plate 302.

[0041] In another embodiment of this application, please refer to Figures 1 to 7 A handle 307 is provided on the lower mold base plate 302. According to the structure provided in this embodiment, the handle 307 provided on the upper mold base plate is beneficial for the operator to push and pull the lower mold base plate 302 relative to the lower mold fixing plate 301, thereby further reducing the difficulty of mold replacement.

[0042] In another embodiment of this application, please refer to Figures 1 to 7 At least two guide posts 308 are vertically fixed on the lower mold base plate 302. The target lower mold 402 is sleeved on the guide posts 308 and the lower end face of the target lower mold 402 abuts against the lower mold base plate 302. The target upper mold 401 is provided with a guide sleeve 309 corresponding to the guide posts 308. According to the structure provided in this embodiment, the minimum two guide posts 308 provided on the lower mold base plate 302 can quickly realize the installation of the target lower mold 402 on the lower mold base plate 302. That is, during installation, it is only necessary to insert the guide hole on the target lower mold 402 corresponding to the guide post 308 into the guide post 308 and push the target lower mold 402 down to abut against the lower mold base plate 302 to complete the connection between the target lower mold 402 and the lower mold base plate 302. It can be understood that since at least two of the guide posts 308 can completely restrict the rotational freedom of the target lower mold 402 relative to the lower mold base plate 302 in the horizontal direction, and since the weight of the target lower mold 402 itself can stabilize the target lower mold 402, the lower mold 402 can be stabilized. The target lower mold 402 is fixedly placed on the lower mold base plate 302, so that the target lower mold 402 can be fixedly installed on the lower mold base plate 302. When disassembling, the target lower mold 402 can be taken out upward along the guide post 308, so that the target lower mold 402 can be easily disassembled and assembled. On the other hand, the target upper mold 401 is provided with guide sleeves 309 corresponding to the guide post 308, so that the target upper mold 401 is fitted on the guide post 308 through the guide sleeves 309. This helps to make the target upper mold 401 and the target lower mold 402 correspond to each other more accurately. In this way, the target upper mold 401 and the target lower mold 402 can be assembled outside the frame 100 and then sent into the frame 100, which helps to further reduce the difficulty of mold replacement.

[0043] In another embodiment of this application, please refer to Figures 1 to 7A clearance cavity 102 is formed on the frame 100 to allow for the movement path of the locking bolt 304. According to the structure provided in this embodiment, the operator can easily adjust the locking bolt 304 from the clearance cavity, which helps to further reduce the difficulty of mold replacement.

[0044] In another embodiment of this application, please refer to Figures 1 to 7 The frame 100 includes a rear fixing plate 103, on which an opening slot 104 corresponding to the cavity 102 is provided. According to the structure provided in this embodiment, the opening slot 104 allows the operator to enter the cavity 102 from outside the frame 100 and adjust the locking bolts, which helps to further reduce the difficulty of mold replacement.

[0045] In another embodiment of this application, please refer to Figures 1 to 7 The frame 100 has a door panel 105 corresponding to the position of the upper mold fixing plate 202 and capable of opening to allow the target upper mold 401 to pass through. According to the structure provided in this embodiment, the openable door panel 105 facilitates the easier insertion of the installed target upper mold 401 and target lower mold 402 from the outside of the frame 100 into the interior of the frame 100, further reducing the difficulty of mold replacement. Furthermore, when the door panel 105 is closed, it provides good protection for the various structures inside the frame 100.

[0046] In another embodiment of this application, please refer to Figures 1 to 7 Multiple sets of first through holes 203, second through holes 204, and tie rod bolts 201 are provided. According to the structure provided in this embodiment, by providing multiple sets of first through holes 203, second through holes 204, and tie rod bolts 201, it is beneficial to form a better fixation for the target upper mold 401, thereby ensuring that the blister forming device provided in this embodiment can operate stably for a long time.

[0047] In another embodiment of this application, please refer to Figures 1 to 7 The first through hole 203 is an oblong hole. According to the structure provided in this embodiment, the oblong hole 203 makes it easier for the tie rod bolt 201 to be connected to the corresponding threaded hole on the target upper mold 401 through the first through hole 203, which helps to further reduce the connection difficulty of the target upper mold 401 and reduce the difficulty of mold replacement.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
