[0026] Please refer to the attached document. Figures 1-5In this embodiment, the mold opening / closing device assembly 100 includes a first mold opening / closing device module 10 and a second mold opening / closing device module 20. The first mold opening / closing device module 10 includes a first screw 11 and a resin sleeve 12. The first screw 11 is used to connect to a first mold steel plate. The resin sleeve 12 is sleeved on the first screw 11 and located on one side of the end of the first screw 11. The outer diameter of the resin sleeve 12 is larger than the outer diameter of the end of the first screw 11. The resin sleeve 12 covers part of the stud portion of the first screw 11. The second mold opening / closing device module 20 includes an annular sleeve 21, which is used to connect to a second mold steel plate. The second mold steel plate and the first mold steel plate are connected... The annular sleeve 21 is fitted onto the resin outer sleeve 12 when the second mold steel plate and the first mold steel plate are in a closed state. The annular sleeve 21 is provided with a positioning boss 211, which is positioned and connected to the second mold steel plate. The annular sleeve 21 is provided with an exhaust channel 21a, the inlet of which faces the end of the first screw 11. The annular sleeve 21 and the resin outer sleeve 12 have a clearance fit structure, so that there is no friction through the clearance fit structure, avoiding mutual interference between the annular sleeve 21 and the resin outer sleeve 12. At the same time, the exhaust channel 21a realizes the exhaust and pressure relief, improving the opening and closing effect of the mold opening and closing device assembly 100.

[0027] Please refer to the attached document. Figures 1-5 In this embodiment, the first mold opening / closing module 10 includes a first screw 11 and a resin sleeve 12. The first screw 11 is used to connect to the first mold steel plate so that the first screw 11 locks the first mold steel plate, thereby facilitating the connection between the first mold opening / closing module 10 and the first mold steel plate through the first screw 11. The resin sleeve 12 is sleeved on the first screw 11 and is located on one side of the end of the first screw 11 so that the resin sleeve 12 is fixed to the first screw 11. The outer diameter of the resin sleeve 12 is larger than the outer diameter of the end of the first screw 11. The resin sleeve 12 covers part of the stud portion of the first screw 11 so that the part of the stud portion of the first screw 11 exposed in the resin sleeve 12 can be connected to the first mold steel plate.

[0028] The second mold opening / closing module 20 includes an annular sleeve 21, which is used to connect to the second mold steel plate. This allows the second mold opening / closing module 20 to connect to the second mold steel plate via the annular sleeve 21, enabling the second mold steel plate and the first mold steel plate to open or close. When the second mold steel plate and the first mold steel plate are closed, the annular sleeve 21 is fitted onto the resin outer sleeve 12. The annular sleeve 21 is provided with a positioning boss 211. The positioning connection of the second mold steel plate ensures the positional accuracy between the annular sleeve 21 and the second mold steel plate; the annular sleeve 21 is provided with an exhaust channel 21a, the inlet of which faces the end of the first screw 11; the annular sleeve 21 and the resin jacket 12 have a clearance fit structure, so that there is no friction through the clearance fit structure, avoiding mutual interference between the annular sleeve 21 and the resin jacket 12. At the same time, the exhaust channel 21a realizes the exhaust and pressure relief, improving the mold opening and closing effect of the mold opening and closing device assembly 100.

[0029] Please refer to the attached document. Figures 1-5 In this embodiment, the annular sleeve 21 detaches from or is fitted onto the resin outer sleeve 12 as the second mold steel plate and the first mold steel plate open and close; when the second mold steel plate and the first mold steel plate open, the annular sleeve 21 detaches from the resin outer sleeve 12. When the second mold steel plate and the first mold steel plate close, the annular sleeve 21 is fitted onto the resin outer sleeve 12.

[0030] The annular sleeve 21 has a first inner cavity 21b for the resin outer sleeve 12 to pass through, so that the resin outer sleeve 12 can fully utilize the space of the first inner cavity 21b. The resin outer sleeve 12 and the first inner cavity 21b are in a clearance fit. The clearance between the peripheral sidewall of the resin outer sleeve 12 and the inner sidewall of the first inner cavity 21b is 0-0.1mm on one side, so that the resin outer sleeve 12 can achieve a clearance fit with the first inner cavity 21b. This clearance fit structure eliminates friction and avoids interference between the annular sleeve 21 and the resin outer sleeve 12, improving the mold opening and closing effect of the mold opening and closing device assembly 100. Optionally, both the annular sleeve 21 and the resin outer sleeve 12 are resin parts.

[0031] Please refer to the attached document. Figures 4-5In this embodiment, the positioning boss 211 is circumferentially disposed on the peripheral sidewall of the annular sleeve 21 and positions and connects to the second mold steel plate, ensuring the positional accuracy of the positioning boss 211 and the second mold steel plate. The positioning boss 211 has an arc surface 2111, which extends toward the peripheral sidewall of the annular sleeve 21 and is adapted to the second mold steel plate, ensuring the connection stability between the positioning boss 211 and the second mold steel plate and preventing accidental separation between the positioning boss 211 and the second mold steel plate. Optionally, the diameter of the arc surface 2111 is 10-20 mm.

[0032] Please refer to the attached document. Figures 4-5 In this embodiment of the application, the annular sleeve 21 includes an annular body 212 and a support arm 213; the support arm 213 is disposed on the upper side of the annular body 212 and connected to the annular body 212; the positioning boss 211 is connected to the annular body 212 and is located at one end of the annular body 212 away from the support arm 213, so that the positioning boss 211 can be fixed to the lower end of the annular body 212.

[0033] The positioning boss 211 and the peripheral sidewall of the annular body 212 have a stepped structure, which ensures the connection strength between the positioning boss 211 and the second mold steel plate and avoids easy separation between the positioning boss 211 and the second mold steel plate; the exhaust channel 21a is opened in the support arm 213 so that the gas can be discharged from the top through the support arm 213 for depressurization.

[0034] Please refer to the attached document. Figures 4-5 In this embodiment, the first inner cavity 21b is formed in the annular body 212; the exhaust channel 21a is arranged along the length of the support arm 213 and connects to the first inner cavity 21b of the annular body 212, so that gas can flow to the external environment through the first inner cavity 21b and the exhaust channel 21a, thereby achieving the exhaust effect.

[0035] Please refer to the attached document. Figures 4-5 In this embodiment of the application, the exhaust channel 21a is arranged in an L-shape; the exhaust channel 21a is used to discharge gas outward to relieve pressure on the first inner cavity 21b of the annular body 212. The L-shaped arrangement enables the gas to be discharged to the side, avoiding external gas from entering the exhaust channel 21a from top to bottom.

[0036] Please refer to the attached document. Figures 4-5 In this embodiment of the application, the exhaust channel 21a is provided with a first channel 21c and a second channel 21d. The first channel 21c is located between the first inner cavity 21b and the second channel 21d. The inner diameter of the first channel 21c is the same as the inner diameter of the second channel 21d. The first channel 21c connects the first inner cavity 21b and the second channel 21d so that the gas in the first inner cavity 21b can flow through the first channel 21c to the second channel 21d and be discharged outward, thereby achieving pressure relief.

[0037] Please refer to the attached document. Figures 4-5 In this embodiment of the application, the first channel 21c and the second channel 21d are perpendicular to each other. The first channel 21c is arranged in the vertical direction and the second channel 21d is arranged in the horizontal direction, so as to realize that the exhaust channel 21a is arranged in an L-shape.
