The limit mechanism includes a limiter 8, a pin 4, a limit block 10 and a drive assembly. The limiter 8 is fixedly arranged at one end of the box body 9, and the drive assembly is arranged at one end of the cover 7. The drive assembly can move up and down in the vertical direction of one end of the cover 7, and the drive assembly is movable away from one end of the cover 7 and extends out of the limiter 8. A square groove is provided inside the limiter 8, one side of the pin 4 is movably arranged inside the square groove, and the pin 4 is movably extended out of the limiter 8 away from the side of the machine cover 7, and the limit block 10 is movably arranged inside the square groove, and the limit block 10 is fixedly arranged at one end of the pin 4, and the limit block 10 is movably extended out of the square groove away from one end of the pin 4. The bottom of the limit block 10 is movably connected to the top of the drive assembly, and snap blocks are fixed on both sides of the inside of the box body 9. The snap blocks are used to play a better snapping effect when the machine cover 7 is connected to the box body.

[0029] The driving assembly includes a lifting rod 5, a movable rod 2 and a transmission member. The lifting rod 5 is movably arranged inside the machine cover 7. The bottom of the lifting rod 5 is movably extended from the inside of the machine cover 7. The movable rod 2 is fixedly arranged at the end of the lifting rod (5) away from the machine cover 7. The movable rod 2 is movably extended from the end of the lifting rod 5 to the inside of the limiter 8. The end of the movable rod 2 away from the lifting rod 5 is movably connected to the limit block. The end of the movable rod 2 away from the lifting rod 5 is movably connected to the end of the limit block 10. The bottom of the transmission member is fixedly arranged inside the machine cover 7. The top of the transmission member is slidably connected to the inside of the machine cover 7. The transmission member includes a spring 6 and a transmission part. The bottom of the transmission part is fixedly arranged at the top of the spring 6. The top of the transmission part is movably connected to the inside of the machine cover 7. The transmission part includes a transmission block 1. The bottom of the moving block 1 is fixedly connected to the top of the spring 6, the end of the transmission block 1 away from the spring 6 is movably connected to the inside of the machine cover 7, the top of the transmission block 1 is fixedly connected to the bottom of the lifting rod 5, the square hole is opened inside the machine cover 7, a through hole is opened inside the transmission block 1, the convex frame 11 is fixedly arranged inside the machine cover 7, the bottom of the convex frame 11 is fixedly connected to the inside of the machine cover 7, the fixed column 3 is fixed inside the convex frame 11, the spring 6 is movably sleeved on the outer surface of the fixed column 6, the bottom of the spring 6 is movably arranged inside the convex frame 11, and the lifting rod 5 is provided with a groove 12 at one end near the machine cover 7. The top of the fixed column 3 slides out of the through hole and the square hole respectively, and the top of the fixed column 3 slides to extend into the groove 12. By releasing the limit block 10, the movable rod 2 At this time, the staff pulls the movable rod 2, and the movable rod 2 drives the transmission block 1 to drive the cover 7 to move upward and out of the box body, thereby separating the cover 7 from the box body 9, making the steps for the staff to disassemble the dryer cover 7 easier. The staff can then clean and replace the materials inside the box body 7, which reduces the labor intensity of the staff to a certain extent. If the cover 7 needs to be reinstalled on the box body 9 after being disassembled, the staff first aligns the cover 7 with the locking block inside the box body 9. When the cover 7 fits with the locking block inside the box body 9, the staff presses the movable rod 2 downward to press the movable rod 2 into the limiter 8. At this time, the staff rotates the pin 4, and the pin 4 drives the limit block 10 to move. When the staff stops applying force to the movable rod 2, the movable rod 2 is affected by the limit block 10 and cannot be separated from the limiter 8. The movable rod 2 drives the lifting rod 5 to be unable to move up and down, so that the cover 7 is installed on the top of the box body 9.

[0030] The working principle provided by the utility model is as follows:

[0031] When the raw materials need to be replaced inside the dryer and the staff needs to disassemble the dryer, the staff presses the lifting rod 2 downward, and the lifting rod 2 drives the transmission block 1 to move downward. While the transmission block 1 drives the machine cover 7 to fit with the box body 9, the transmission block 1 also drives the spring 6 to perform compression movement. According to the compressibility of the spring, the spring 6 is compressed to make the machine cover 7 fit more tightly with the box body 9. The inside of the transmission block 1 moves along the outer surface of the fixed column 3 in the compression direction of the spring 6. After the fixed column 3 slides out of the through hole and the square hole in turn, the fixed column 3 moves upward relatively inside the groove 12. The convex frame 11 is located on the outer surface of the bottom of the spring 6, which limits the bottom when the spring 6 is compressed. The fixed column 3 compresses the spring 6 to prevent the overall position from being distorted when the spring 6 is compressed, and the fixed block 5 and the machine cover 7 are driven by the compression of the spring 6. When the staff member presses the movable rod 2 to the bottom of the limiter 8, the pin 4 is rotated to the inside of the limiter 8 to release the downward pressure on the lifting rod 5. Since the limiter 8 is fixed on one side of the box body 9, the top of the transmission block 1 is movably connected to the inside of the machine cover 7, and the bottom of the lifting rod 5 is slidably connected to one end of the machine cover 7. According to the spring resilience, the spring 6 rebounds and drives the transmission block 1 to move upward, and the transmission block 1 drives the lifting rod 2 to move upward. At this time, the movable rod 2 has been disengaged from the limiter 8. The staff member pulls the movable rod 2 upward to complete the separation of the machine cover 7 from the box body 9. Then the staff member can clean and replace the raw materials inside the box body 9. This structure simplifies the disassembly process of the dryer used on the injection molding machine and reduces the labor intensity of the staff to a certain extent.
