[0034] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0035] Example:

[0036] See also Figure 1-Figure 5 A blister tray mold includes a bottom mold (not shown in the figure), a mold core 1, a pressure plate 2 and a pressure rod 3. Specifically, the mold core 1 is arranged above the bottom grinder, the bottom surface of the mold core 1 has a spatial structure, and the bottom grinder has a plurality of convex structures embedded in the spatial structure, and together with the mold cavity 4, a mold cavity 4 is formed, and the shape of the mold cavity 4 is the same as the structure of the blister tray product to be produced.

[0037] A sunken operating space is provided on the top of the mold core 1, and a pressure plate 2 is rotatably provided in the operating space. Generally, a cover plate 5 is provided on the top of the operating space. At the same time, the mold core 1 also has through holes 6 connecting the operating space and the mold cavity 4, and the through holes 6 are distributed in the vertical direction and are straight holes.

[0038] The pressure rod 3 is slidably arranged in the through hole 6, and the length of the pressure rod 3 is greater than the length of the through hole 6, so that the top end of the pressure rod 3 is located in the operating space, and the top end of the pressure rod 3 is movably connected to the pressure plate 2. During the rotation of the pressure plate 2 in the operating space, the pressure rod 3 can be driven to move in the vertical direction, so that the bottom end of the pressure rod 3 can protrude from the bottom surface of the mold core 1.

[0039] A mold core 1 is arranged above the bottom mold, a mold cavity 4 is arranged at the bottom of the mold core 1 , and an operating space is arranged inside the mold core 1 . The operating space and the mold cavity 4 are connected through a through hole 6 on the mold core 1 .

[0040] During the demoulding process, the pressure plate 2 is driven to make the pressure rod 3 move toward the bottom of the mold core 1 in the through hole 6, so that the blister disk adhered to the mold core 1 is pushed out by the pressure rod 3, thereby achieving rapid demoulding and improving production efficiency.

[0041] In one specific embodiment:

[0042] The mold core 1 is provided with a plurality of through holes 6 , and all the through holes 6 are arranged around a circle of the pressure plate 2 . A pressure rod 3 is slidably arranged in each through hole 6 , and the top ends of all the pressure rods 3 are movably connected to the pressure plate 2 .

[0043] In this embodiment, the pressure plate 2 is a circular structure, all the pressure rods 3 are arranged around a circumference of the pressure plate 2 , and the ends of all the pressure rods 3 are movably connected to the circumference of the pressure plate 2 .

[0044] Preferably, a plurality of slide grooves 7 are arranged on the circumference of the pressure plate 2, and the slide grooves 7 are arranged on the pressure plate 2 in an inclined shape, and the number of the slide grooves 7 is equal to the number of the pressure rods 3. The top end of the pressure rod 3 is an L-shaped structure, and the end of the pressure rod 3 is slidably arranged in the slide groove 7, and each slide groove 7 is matched with a pressure rod 3. When the top end of the pressure rod 3 is located at the top end of the slide groove 7, the bottom end of the pressure rod 3 and the top surface of the mold cavity 4 are on the same plane.

[0045] In this embodiment, during the rotation of the pressing plate 2, since the end of the pressing rod 3 is slidably disposed in the chute 7, the pressing plate 2 can directly drive the pressing rod 3 to move downward, so that the bottom end of the pressing rod 3 protrudes from the bottom surface of the mold core 1, thereby achieving the purpose of pushing the product out. After the product is pushed out of the mold cavity 4, the pressing plate 2 is rotated in the opposite direction to make the top end of the pressing rod 3 return to the top end of the chute 7.

[0046] In another specific embodiment:

[0047] A circular countersunk hole is provided at the bottom of the operation space, and the circular countersunk hole is rotatably connected to one end of a main shaft 8, the main shaft 8 is arranged in the vertical direction in the operation space, and the above-mentioned pressure rod 3 is fixedly arranged in the middle of the main shaft 8. At the same time, the top of the main shaft 8 passes through the cover plate 5 at the top of the mold core 1, and the middle of the cover plate 5 has a hole for the main shaft 8 to pass through, and a sunken hexagonal connection part 9 is provided at the top of the main shaft 8.

[0048] In this embodiment, a tool such as a wrench can be inserted into the hexagonal connection portion 9 to directly drive the main shaft 8 and the pressure plate 2 to rotate. In addition, the top surface of the main shaft 8 and the top surface of the mold core 1 are on the same horizontal plane.

[0049] In another specific embodiment:

[0050] The shape of the mold cavity 4 is the same as that of the blister tray product, and the raised portion at the bottom of the mold core 1 constitutes a receiving portion for the blister tray. The bottom ends of all the above-mentioned pressure rods 3 are located on the receiving portion for the blister tray product, thereby avoiding the problem of deformation of the blister tray product when the blister tray product is pushed out.

[0051] In another specific embodiment:

[0052] The cross section of the pressing rod 3 is a polygonal structure, which can prevent the pressing rod 3 from rotating in the through hole 6 .

[0053] In another specific embodiment:

[0054] The top end of the pressure rod 3 is rotatably connected to a rotating shaft, and the rotating shaft is slidably arranged in the chute 7. By rotating the rotating shaft, the friction between the end of the pressure rod 3 and the chute 7 can be reduced, which can reduce the loss on the one hand and reduce the noise on the other hand.

[0055] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
