Detailed implementation manners

[0024] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0025] As Figures 1 to 5 shown, the short-bolt single-hole pipe clamp injection mold of the present utility model includes:

[0026] A mounting base 1 and a driving assembly. A support member 2 is arranged on the mounting base 1, a fixed injection mold 3 is arranged on the support member 2, the driving assembly is arranged on the support member 2, a mounting member 4 is arranged on the driving assembly, a transmission shaft 5 is arranged in the shaft hole of the mounting member 4, two groups of transmission shafts 5 are coaxially arranged and are respectively located at both ends of the movable injection mold 6, the movable injection mold 6 is arranged corresponding to the fixed injection mold 3, and the driving assembly is used for lifting and adjusting the movable injection mold;

[0027] A transmission assembly is arranged on the mounting base 1, and the transmission assembly is used for driving the movable injection mold 6 to rotate by the transmission shaft 5; the fixed injection mold 3 is stably supported on the mounting base 1 through the support member 2, the movable injection mold 6 is rotationally supported through the transmission shaft 5, the movable injection mold 6 is connected with the driving assembly through the mounting member 4, the driving assembly provides lifting power for the movable injection mold 6, the movable injection mold 6 is lifted to cooperate with the fixed injection mold 3 for injection molding, and after injection molding, they are separated to facilitate the demolding of the pipe clamp. The transmission assembly provides rotational power for the movable injection mold 6, and the pipe fitting is automatically demolded by gravity through the flipping of the movable injection mold 6, which not only reduces the manual demolding process, but also improves safety and prevents the pipe clamp from scalding the staff due to overheating.

[0028] As Figures 1 to 5As shown in the figure, as a preferred solution, the transmission assembly includes a transmission gear 7 coaxially arranged on the transmission shaft 5 and a limit assembly. The limit assembly is arranged on the mounting base 1. A connecting piece 8 is arranged on the limit assembly, a fixing piece 9 is arranged on the connecting piece 8, a straight rack 10 is arranged in the inner groove of the fixing piece 9, and the straight rack 10 is in meshing transmission connection with the transmission gear 7. The limit assembly includes a positioning piece 11 arranged on the mounting base 1. The positioning piece 11 is arranged in the polygonal inner hole of the connecting piece 8. A limiting piece 12 is arranged on the positioning piece 11. Springs 13 are respectively in contact with both ends of the fixing piece 9, and the two ends of the springs 13 are respectively fixedly connected with the limiting piece 12 and the mounting base 1. The movement track of the connecting piece 8 is limited by the cooperation of the positioning piece 11 and the polygonal inner hole of the connecting piece 8. The straight rack 10 is cooperatively installed on the connecting piece 8 through the fixing piece 9. The injection molding moving die is provided with a turning power through the relative movement of the transmission gear 7 and the straight rack 10. After the injection molding moving die 6 is turned to a set angle, the rotation stops. After that, the straight rack 10 and the transmission gear 7 no longer rotate relative to each other. Then the straight rack 10 follows the injection molding moving die 6 and moves synchronously. By arranging the springs 13, during the reset process of the injection molding fixed die, the injection molding fixed die 6 first performs a linear motion. Until the reset force of the spring 13 is less than the turning friction resistance of the injection molding moving die 6, the injection molding moving die 6 then performs a turn.

[0029] As Figures 1 to 5 As shown in the figure, as a preferred solution, a partition piece 14 is arranged inside the shaft hole of the mounting piece 4. A limit groove is arranged on the transmission shaft 5. The partition piece 14 is arranged in the limit groove of the transmission shaft 5. The cooperation of the partition piece 14 and the limit groove of the transmission shaft 5 limits the maximum turning angle of the injection molding moving die 6 to 180°. Through the interaction between the partition piece 14 and the limit groove of the transmission shaft 5, the maximum turning angle of the injection molding moving die 6 is limited to 180°, so that the injection molding moving die 6 is always in the angle with the bevel teeth facing up or down when in linear motion. This design ensures the stable cooperation between the injection molding moving die 6 and the injection molding fixed die 3, and the tube clamp is demolded by gravity.

[0030] As Figures 1 to 5As shown, as a preferred solution, the driving assembly includes two sets of conductive members 15 symmetrically arranged in the through holes of the support member 2. The transmission member 15 is arranged on the mounting base 1. The conductive member 15 is provided with external threads, and a moving member 16 is arranged at the external thread of the conductive member 15. The moving member 16 is slidably connected to the support member 2. The mounting member 4 is arranged on the moving member 16. The two sets of moving members 16 are driven by a power assembly. The power assembly includes a servo motor 17 arranged on the support member 2. The output end of the servo motor 17 is coaxially provided with a driving sprocket 19. Two sets of driven sprockets 20 are coaxially arranged on the two sets of moving members 16 respectively. A chain 21 is meshed and installed on the driving sprocket 19 and the two sets of driven sprockets 20. A protective member 22 is arranged on the support member 2. The chain 21 is located inside the protective member 22. Through the precise control of the servo motor 17, the positions of the moving member 16 and the mounting member 4 can be easily adjusted. The servo motor 17 drives the rotation of the transmission member 15 through the cooperation of the chain 21 with the driving sprocket 19 and the two sets of driven sprockets 20 respectively. The working position of the injection molding moving die 6 is adjusted by the cooperation of the external threads of the transmission member 15 with the moving member 16. The protective member 22 arranged on the support member 2 effectively wraps the chain 21, preventing the intrusion of external foreign objects and accidental contact by operators, and greatly improving the operation safety.

[0031] As Figures 1 to 5 shown, as a preferred solution, multiple sets of support feet 23 are arranged at the bottom end of the mounting base 1; the multiple sets of support feet 23 are evenly distributed at the bottom of the mounting base, effectively dispersing the overall weight of the mounting base and the dynamic load generated during work, ensuring the stable placement of the device under various workbench surfaces or ground conditions, avoiding shaking or tilting caused by unstable center of gravity, and improving the stability and precision of the injection molding process.

[0032] As Figures 1 to 5 shown, as a preferred solution, the bottom end of the mounting base 1 is set as an inclined surface, and a storage box 24 is arranged at the lower end of the inclined surface; the inclined surface design and the storage box 24 below enable the centralized diversion and collection of the pipe clamps after demolding.

[0033] As Figures 1 to 5 shown, as a preferred solution, the working process is as follows:

[0034] First, start the servo motor 17. The chain 21 cooperates with the driving sprocket 19 and the driven sprocket 20 respectively to make the conducting member 15 rotate. Then, the conducting member 15 rotates and drives the moving member 16 to drive the mounting member 4 to move upward. After that, the moving connecting member 8 is blocked by the spring 13. The straight rack 10 and the transmission gear 7 rotate relative to each other to make the injection moving die 6 turn over 180°. Then, the rotation of the injection moving die 6 is restricted by the blocking member 14. Then, the relative movement of the straight rack 10 and the transmission gear 7 provides for compressing the spring 13. Then, the injection moving die 6 and the injection fixed die 3 cooperate, and then injection molding can be carried out. After the injection molding is completed and cooled, the servo motor 17 rotates reversely. Then, the injection moving die 6 is disconnected from the injection fixed die 3. During this process, the connecting member 8 moves downward under the reset elastic force of the spring 13. When it contacts the bottom spring 13 and the elastic forces of the two groups of springs 13 reach balance, the straight rack 10 and the transmission gear 7 rotate relative to each other. Then, the injection moving die 6 turns over, and then the pipe clamp is demolded by gravity and then collected in the storage box 24.

[0035] For the injection mold for the short bolt single-hole pipe clamp of the present utility model, its installation method, connection method or setting method are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0036] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
