Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, and particularly relates to a cooling device for plastic pipe injection molding. Background Technique

[0002] Plastic pipes are generally made of synthetic resin, that is, polyester, as raw materials, and stabilizers, lubricants, plasticizers, etc. are added, and are processed by extrusion in a pipe making machine by the method of "plastic molding". During the injection molding process of plastic pipes, cooling plays a crucial role. Currently, after the plastic pipes are injection molded, they are usually uniformly placed in a cooling water tank for cooling. However, when there are many plastic pipes to be cooled, it is not convenient to salvage them all at once, which is likely to affect the subsequent processes.

[0003] After retrieval, the utility model with the patent publication number CN212826670U discloses a cooling device for a plastic pipe clamp injection molding machine. It replaces manual work to salvage the cooled products by setting a ladle that can rotate around the water tank. The power part selects a simple pulley and steel wire rope combination, and at the same time, a discharge plate and a conveyor belt are used in cooperation, so that the cooled products can directly enter the next process. Although it is convenient to salvage the cooled plastic pipes, when there are many plastic water pipes in the ladle, the cooling degrees of the plastic pipes in the outer part and the middle part are different. When the plastic pipes in the outer part are cooled and salvaged from the cooling water, the plastic pipes in the middle part may still have a certain temperature and are not completely cooled, thus reducing the overall cooling effect on multiple injection-molded plastic pipes.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0046] Such as Figures 1 to 5As shown in the figure, this embodiment proposes a cooling device for plastic pipe injection molding, including a water tank 1, a support frame 2, a moving cylinder 3, a lifting frame 4, a cooling box 5, and a baffle screen 6.

A plurality of water passing ports are opened on the cooling box 5, facilitating the cooling of the plastic pipes in the cooling box 5 by cooling water. The baffle screen 6 is rotatably installed on the cooling box 5 through a driving seat. A blanking port matching the baffle screen 6 is opened on the cooling box 5, and two wear-resistant pads are symmetrically connected at the blanking port, facilitating the increase of the rotational stability of the baffle screen 6 on the cooling box 5. The two sides of the water tank 1 are respectively communicated with a water inlet pipe 22 and a water outlet pipe 23. A water inlet valve and a water outlet valve are respectively arranged on the water inlet pipe 22 and the water outlet pipe 23, facilitating the replenishment of cooling water into the cooling box 5 or the discharge of cooling water from the water tank 1. The water tank 1 can be arranged at the conveying equipment during the plastic pipe injection molding process.

[0047] As Figures 1 to 5 shown, the adjustment component includes a first electric cylinder 7, an adjustment cylinder 8, an elastic rod 9, and an elastic spring 10. An installation port matching the first electric cylinder 7 is opened on the lifting frame 4, and the output end of the first electric cylinder 7 is fixedly connected to the cooling box 5. Two sliding frames 20 are symmetrically connected to the cooling box 5. A sliding groove for the sliding frame 20 to slide is opened on the lifting frame 4, which can increase the stability of the cooling box 5 moving in the lifting frame 4. A plurality of adjustment cylinders 8 are provided. A plurality of adjustment cylinders 8 are all fixedly connected to the inner side wall of the lifting frame 4. The elastic rod 9 is slidably connected through each adjustment cylinder 8, and the elastic rod 9 is fixedly connected to the cooling box 5. The elastic spring 10 is fixedly connected between each elastic rod 9 and the adjacent adjustment cylinder 8. Two limit blocks 19 are symmetrically connected to the elastic rod 9. A limit groove for the limit block 19 to slide is opened on the adjustment cylinder 8, facilitating the increase of the sliding stability of the elastic rod 9 in the elastic cylinder;

[0048] By pushing the cooling box 5 through the first electric cylinder 7, the cooling box 5 can move back and forth in the lifting frame 4. At the same time, through the cooperation of the elastic spring 10 and the limit block 19, the elastic rod 9 can move back and forth in the adjustment cylinder 8, so as to increase the stability of the cooling box 5 moving back and forth in the lifting frame 4, thereby enabling a plurality of plastic pipes to shake in the cooling box 5, facilitating the all-round cooling of a plurality of plastic pipes.

[0049] As Figures 1 to 5As shown, the material transfer assembly includes a second electric cylinder 11, a moving bar 12 and a moving plate 13. The second electric cylinder 11 is installed on one side of the support frame 2, and the output end of the second electric cylinder 11 penetrates through the support frame 2 and is fixedly connected to the moving cylinder 3. A mounting plate 21 is fixedly connected to one side of the support frame 2, and the second electric cylinder 11 is installed on the top of the mounting plate 21, facilitating the stable installation of the second electric cylinder 11. The moving bar 12 is fixedly connected to the top of the moving cylinder 3. A moving opening for the moving bar 12 to move is provided on the support frame 2. The moving plate 13 is fixedly connected to the moving bar 12. A moving groove for the moving plate 13 to move is provided on the support frame 2, facilitating the increase of the stability of the moving bar 12 moving in the moving opening.

[0050] By pushing the moving cylinder 3 through the second electric cylinder 11, the moving cylinder 3 can move stably under the support frame 2 through the cooperation of the moving plate 13 and the moving bar 12, thus facilitating the lifting frame 4 to drive the plastic pipe to a suitable blanking position through the cooling box 5.

[0051] As Figures 1 to 5 shown, the lifting seat includes a third electric cylinder 14, a lifting frame 15 and a lifting rod 16. The third electric cylinder 14 is installed in the moving cylinder 3. The lifting frame 15 is fixedly connected between the output end of the third electric cylinder 14 and the lifting frame 4. The lifting rods 16 are provided in two. The two lifting rods 16 are fixedly connected between the output end of the third electric cylinder 14 and the lifting frame 15.

[0052] Through the cooperation of the third electric cylinder 14, the lifting frame 15 and the lifting rod 16, it is convenient to lift the lifting frame 4 back and forth in the water tank 1, thus facilitating the cooling box 5 and the plastic pipe to enter the cooling water.

[0053] As Figures 1 to 5 shown, the driving seat includes a motor 17 and a driving rod 18. The motor 17 is installed on the top of the lifting frame 4.

[0054] Through the material blocking net plate 6, it is convenient to block the blanking port on the cooling box 5, so as to increase the stability of the plastic pipe placed in the cooling box 5. At the same time, by rotating the driving rod 18 through the motor 17, the material blocking net plate 6 can rotate in a circular motion with the driving rod 18 as the center, so that the material blocking net plate 6 can gradually rotate away from the cooling box 5, and the blanking port can be exposed, so that the plastic pipe in the cooling box 5 can fall and be discharged through the blanking port.

[0055] In this embodiment, after placing multiple plastic pipes in the cooling box 5, the lifting frame 15 is pushed by the third electric cylinder 14, so that the lifting frame 4 drives the cooling box 5 and the plastic pipes into the cooling water in the water tank 1. At the same time, the cooling box 5 is pushed back and forth by the first electric cylinder 7, so that the multiple plastic pipes can shake in the cooling box 5 to facilitate the all-round cooling of the multiple plastic pipes. After the cooling is completed, the lifting frame 15 is pulled upward by the third electric cylinder 14, so that the lifting frame 4 and the cooling box 5 are moved to a suitable height. Then, the moving cylinder 3 is pushed by the second electric cylinder 11, so that the moving cylinder 3 drives the third electric cylinder 14, the lifting frame 15, the lifting frame 4, the cooling box 5 and the plastic pipes to move to a suitable blanking position. Then, the driving rod 18 is rotated by the motor 17, so that the driving rod 18 drives the material blocking net plate 6 to rotate. When the material blocking net plate 6 rotates out of the blanking port, the multiple plastic pipes will be blanked through the blanking port to the conveying equipment for conveying.

[0056] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
