Description

Technical Field

[0001] The utility model relates to the technical field of polyimide film manufacturing, in particular to a mold for manufacturing polyimide film. Background Art

[0002] Polyimide film is a high-temperature resistant insulating material for motors and electrical appliances, including two types: pyromellitic polyimide film and biphenyl polyimide film. The former is a product of DuPont Company in the United States, prepared from pyromellitic dianhydride and diaminodiphenyl ether. The latter is produced by Ube Industries, Ltd. in Japan, prepared from biphenyltetracarboxylic dianhydride and diphenyl ether diamine (type R) or m-phenylenediamine (type S).

[0003] In the process of manufacturing polyimide film, it is often necessary to open uniform holes on the film surface. During the process of opening holes, a mold is required to support the film. However, most of the existing molds for manufacturing polyimide film do not have the function of replacing the mold plate. Since different aperture mold plates need to be replaced when opening holes of different sizes, the adaptability is poor, which is not conducive to the use of workers. Therefore, we propose a mold for manufacturing polyimide film. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a mold for manufacturing polyimide film to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Preferably, a support plate is fixedly connected to one side of one of the fixing plates, and the motor is fixedly installed on the support plate.

[0008] Preferably, the traction and winding component includes a traction roller rotatably connected between two of the fixing plates, and the same winding roller is rotatably connected between the other two fixing plates.

[0009] Preferably, one end of the winding roller is fixedly connected with a rotating shaft, one end of the rotating shaft extends to the other side of the fixing plate, and the other end of the rotating shaft is fixedly connected to the output end of the motor.

[0010] Preferably, the opening and closing assembly includes a door hinged to one side of the collection box, and a handle is fixedly connected to one side of the door.

[0011] Preferably, the fixing assembly includes two symmetrically distributed connecting plates fixedly connected to one side of the installation shell. One side of the connecting plate is threadedly connected with a bolt, and one end of the bolt is fixedly connected with a clamping block.

[0012] Preferably, one end of the bolt is fixedly connected with a turning handle, and the material of the turning handle is rubber.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: During the film-making process of polyimide film, it is often necessary to open uniform holes on the film surface. During the process of opening the holes, a mold is required to support the film. By respectively installing both ends of the film on the traction roller and the winding roller, and starting the motor, the output end of the motor drives the rotating shaft and the winding to rotate at this time. Then the film can pass through the mold plate for winding operation. When the mold plate needs to be replaced, by holding and turning the turning handle, the bolt can be driven to rotate, and then the clamping block can be driven to move. At this time, the clamping block moves away from the mold plate, and the mold plate can be taken out from the inside of the installation groove opened on the installation shell. Then the mold plate can be replaced. By reversing the turning handle, the replaced mold plate can be fixed. Through the provided collection box, the film waste after punching can be collected. Through the above structures provided, it is convenient for the staff to support the film with a mold during the process of opening holes in the polyimide film-making process, the mold plate can be replaced according to the size of the opened holes, the disassembly and assembly operation of the mold plate is simple and time-consuming is short, which greatly facilitates the use of the staff.

A traction and winding assembly is arranged between the four fixing plates 2. The traction and winding assembly includes a traction roller 3 rotatably connected between two of the fixing plates 2, and the same winding roller 4 is rotatably connected between the other two fixing plates 2. Through the arranged traction and winding assembly, the film can be traction-wound. One end of the winding roller 4 is fixedly connected with a rotating shaft 7, one end of the rotating shaft 7 extends to the other side of the fixing plate 2, and the other end of the rotating shaft 7 is fixedly connected to the output end of a motor 6. A motor 6 is arranged on one side of one of the fixing plates 2, and a support plate 5 is fixedly connected to one side of one of the fixing plates 2. The motor 6 is fixedly installed on the support plate 5. Through the arranged support plate 5, the phenomenon that the motor 6 idles during operation can be avoided.
