Description

Technical Field

[0001] The utility model relates to the technical field of modified polyphenylene ether foam product processing, in particular to a pneumatic opening and closing device used for modified polyphenylene ether foam product processing. Background Art

[0002] Modified polyphenylene ether is a polyphenylene ether material modified by polystyrene or other polymers. This material has excellent electrical insulation and water resistance, as well as good dimensional stability. Its dielectric properties rank first among plastics. Modified polyphenylene ether is designed to eliminate stress cracking tendency and improve its original performance by adding polystyrene or other polymers to meet a wider range of application needs.

[0003] Modified polyphenylene ether is mainly obtained by blending polyphenylene ether and polystyrene. After modification, compared with polyphenylene ether, its melt viscosity is lower, injection molding is easier, and stress cracking is not easy to occur after molding. Modified polyphenylene ether foam products need to be injected into the mold during production, cooled and hardened before molding, and the closure of the mold needs to be blocked by a pneumatic opening and closing device.

[0004] The existing pneumatic opening and closing devices for processing modified polyphenylene ether foam products do not all have a single conveying shaft rod and have poor load-bearing capacity. Therefore, a pneumatic opening and closing device for processing modified polyphenylene ether foam products is proposed. The device adopts a three-axis connection design. The connecting column drives the mold to open and close, and the auxiliary rod improves its load-bearing capacity without affecting the movement of the mold. Utility Model Content

[0005] In view of the problems in the prior art, the utility model provides a pneumatic opening and closing device for processing modified polyphenylene ether foam products. It adopts a three-axis connection design. The connecting column pushes the mold to open and close, and the auxiliary rod improves its load-bearing capacity without affecting the movement of the mold.

[0006] The technical solution adopted by the utility model to solve the technical problem is a pneumatic opening and closing device for processing modified polyphenylene ether foam products, comprising a shell, a first limiting groove is provided inside the shell, second limiting grooves are provided inside the shell on both sides of the first limiting groove, an auxiliary rod is sleeved at one end of the second limiting groove, a sealing limiting assembly is provided at one end of the shell, and the sealing limiting assembly includes a limiting sleeve connected to one end of the shell;

[0007] A sealing sleeve is glued to the inner side of the limit sleeve, a connecting column is provided inside the limit sleeve, one end of the connecting column located inside the first limit groove is fixed with a piston block by bolts, and a retaining ring is provided at one end of the limit sleeve located outside the connecting column, and an externally threaded insert ring is welded on the side of the retaining ring close to the limit sleeve.

[0008] By adopting the above technical solution, compressed air enters the first limit groove and pushes the connecting column to extend or retract through the piston block, thereby driving the mold to open or close. When the mold moves, the auxiliary rod and the limit block at one end of it slide in the second limit groove, thereby improving the bearing capacity of the device. The limit sleeve and the sealing sleeve inside it are used to limit and seal the connecting column.

[0009] Specifically, one end of the top of the shell is connected to a first one-way valve through a pipeline, one side of the first one-way valve is connected to a first solenoid valve through a threaded groove, the other end of the top of the shell is connected to a second one-way valve through a pipeline, and one side of the second one-way valve is connected to a second solenoid valve through a threaded groove.

[0010] Specifically, the connecting column and one end of the auxiliary rod are fixed with a mounting plate by bolts, and one end of the auxiliary rod located inside the second limiting groove is connected to the limiting block by a threaded groove.

When the mounting plate moves, the auxiliary rod and the limit block at one end thereof are driven to slide in the second limit groove. The auxiliary rod can improve the bearing capacity of the device without affecting the movement of the mounting plate, so that the device can drive a heavier mold to open or close. The limit block plays a limiting role to prevent the auxiliary rod from falling off from the second limit groove. When the limit block moves in the second limit groove, the gas flows through the multiple through holes, and the dustproof net can prevent dust and the like from flowing into the second limit groove through the through holes.

[0016] (2) The utility model discloses a pneumatic opening and closing device for processing modified polyphenylene ether foam products. When the second solenoid valve is opened, the gas in the first limit groove can be discharged, so that the compressed air entering the first limit groove from the first one-way valve can push the piston block and the connecting column on one side thereof to extend.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] The three-axis connection design is adopted. The connecting column drives the mold to open and close. The auxiliary rod improves its bearing capacity without affecting the movement of the mold. Figure 1-4As shown, the pneumatic opening and closing device for processing modified polyphenylene ether foam products described in the utility model comprises a shell 1, a first limiting groove 2 is provided inside the shell 1, second limiting grooves 3 are provided inside the shell 1 on both sides of the first limiting groove 2, an auxiliary rod 7 is sleeved at one end of the second limiting groove 3, a sealing limiting assembly 4 is provided at one end of the shell 1, and the sealing limiting assembly 4 comprises a limiting sleeve 401 connected to one end of the shell 1;

[0025] A sealing sleeve 402 is glued to the inner side of the limiting sleeve 401, a connecting column 5 is penetrated inside the limiting sleeve 401, one end of the connecting column 5 located inside the first limiting groove 2 is fixed with a piston block 6 by bolts, and a retaining ring 404 is provided at one end of the limiting sleeve 401 located outside the connecting column 5, and an external threaded insert ring 405 is welded to the side of the retaining ring 404 close to the limiting sleeve 401.

[0026] When in use, compressed air enters the first limiting groove 2 and pushes the connecting column 5 to extend or retract through the piston block 6, thereby driving the mold to open or close. When the mold moves, the auxiliary rod 7 and the limiting block 8 at one end thereof slide in the second limiting groove 3, thereby improving the bearing capacity of the device. The limiting sleeve 401 and the sealing sleeve 402 inside it are used to limit and seal the connecting column 5.

[0027] For example, Figure 1 As shown, the utility model also includes that one end of the top of the shell 1 is connected to a first one-way valve 17 through a pipeline, one side of the first one-way valve 17 is connected to a first solenoid valve 9 through a threaded groove, and the other end of the top of the shell 1 is connected to a second one-way valve 18 through a pipeline, and one side of the second one-way valve 18 is connected to a second solenoid valve 10 through a threaded groove.

[0028] When in use, the first solenoid valve 9 , the first one-way valve 17 , the second solenoid valve 10 , and the second one-way valve 18 are arranged to facilitate the compressed air to enter the first limiting groove 2 or to be discharged from the first limiting groove 2 .

[0029] For example, Figure 1 , Figure 2 As shown, the utility model also includes that the connecting column 5 and one end of the auxiliary rod 7 are fixed with a mounting plate 16 by bolts, and the end of the auxiliary rod 7 located inside the second limiting groove 3 is connected to the limiting block 8 through a threaded groove.

[0030] When in use, the installation of the mounting plate 16 facilitates the installation of the mold on the end of the connecting column 5 , and the limiting block 8 can prevent the auxiliary rod 7 from falling off from the second limiting groove 3 .

[0031] For example, Figure 3 , Figure 4As shown, the utility model also includes that the shell 1 is provided with a second internal thread groove 15 at one end of the first limiting groove 2, the limiting sleeve 401 is provided with external thread teeth 406 on the outside, and the limiting sleeve 401 is provided with a first internal thread groove 403 on the inside.

[0032] When in use, the second internal thread groove 15 is provided to facilitate screwing the limiting sleeve 401 onto one end of the housing 1 , and the external thread teeth 406 and the first internal thread groove 403 are provided to facilitate screwing the external thread insert ring 405 into the limiting sleeve 401 .

[0033] For example, Figure 3 As shown, the utility model also includes that one end of the second limiting groove 3 is equidistantly penetrated with through holes 14, and one side of the through hole 14 located inside the second limiting groove 3 is fixed with a dustproof net 13 through a card slot.

[0034] When in use, the through hole 14 facilitates the flow of gas in the second limiting groove 3 , and the dustproof net 13 can prevent dust and the like from entering the second limiting groove 3 .

[0035] For example, Figure 3 As shown, the utility model also includes that a first retaining ring 11 is welded to one end of the first limiting groove 2 , and a second retaining ring 12 is welded to one end of the first limiting groove 2 away from the first retaining ring 11 .

[0036] When in use, the first retaining ring 11 and the second retaining ring 12 are used to limit the position of the piston block 6 .

[0037] When the utility model is used, personnel use a mounting frame to fix the housing 1 on an operating table, a base plate or other equipment, use bolts to fix the mold on the mounting plate 16, and use an air pipe to connect the first one-way valve 17 and the second one-way valve 18 to the external gas;

[0038] The external compressed air flows into the first limiting groove 2 through the first one-way valve 17, and the second solenoid valve 10 is opened to allow the gas in the first limiting groove 2 to be discharged, so that the compressed air entering the first limiting groove 2 from the first one-way valve 17 can push the piston block 6 and the connecting column 5 on one side thereof to extend. The external compressed air flows into the first limiting groove 2 through the second one-way valve 18, and the first solenoid valve 9 is opened to allow the gas in the first limiting groove 2 to be discharged, so that the compressed air entering the first limiting groove 2 from the second one-way valve 18 can push the piston block 6 and the connecting column 5 on one side thereof to retract. When the connecting column 5 extends and retracts, it drives the mold installed on the mounting plate 16 to move, so as to close and open the mold.

[0039] When the mounting plate 16 moves, the auxiliary rod 7 and the limiting block 8 at one end thereof are driven to slide in the second limiting groove 3. The auxiliary rod 7 can improve the bearing capacity of the device without affecting the movement of the mounting plate 16, so that the device can drive a heavier mold to open or close. The limiting block 8 plays a limiting role to prevent the auxiliary rod 7 from falling off from the second limiting groove 3. When the limiting block 8 moves in the second limiting groove 3, the gas flows through the multiple through holes 14, and the dustproof net 13 can prevent dust and the like from flowing into the second limiting groove 3 through the through holes 14;

[0040] The connecting column 5 passes through the limiting sleeve 401, and the limiting sleeve 401 can limit the connecting column 5 without affecting its movement to prevent the connecting column 5 from tilting. The external threaded insert ring 405 is screwed into the limiting sleeve 401 through the first internal thread groove 403, so that the retaining ring 404 is tightly attached to one end of the limiting sleeve 401, and the external threaded insert ring 405 squeezes the sealing sleeve 402 to deform it and fully fill the space between the limiting sleeve 401 and the connecting column 5, so as to seal the space between the limiting sleeve 401 and the connecting column 5;

[0041] The first retaining ring 11 and the second retaining ring 12 are provided to limit the piston block 6 so that the piston block 6 does not stick to the inner wall of the second limiting groove 3, thereby preventing the compressed air entering the second limiting groove 3 from being unable to push the piston block 6.
