Description

Technical Field

[0001] The present invention belongs to the technical field of plastic bucket production. Specifically, it relates to an injection molding device for plastic bucket processing. Background Technique

[0002] Plastic buckets are mostly made of plastics such as polyethylene and polypropylene by blow molding and injection molding, and are used as outer packages for liquid and solid items in industries such as chemical industry, pesticides, medicine, food, hardware electronics, and mechanical and electrical industries.

[0003] Chinese Patent with the application number CN202323178120.4 discloses an injection molding device for plastic buckets, including an operation table and a fixed column. The fixed column is fixedly installed on the upper surface of the operation table. An adjustment mechanism is arranged on the upper surface of the operation table. The adjustment mechanism includes a moving unit and a mold unit. The moving unit includes a threaded column installation groove, a threaded column, a moving block, and a driving motor. The threaded column installation groove is opened on the side of the fixed column. The threaded column is installed on the inner wall of the threaded column installation groove. The moving block is fixedly installed on the outer surface of the threaded column. In this injection molding device for plastic buckets, by setting the adjustment mechanism, the rotation of the threaded column makes the moving block drive the bottom plate to move on the outer surface of the threaded column. The mold base fixedly installed on the upper surface of the bottom plate follows to move to the bottom surface of the mold base cover for injection molding operation. After injection molding, it moves in the reverse direction to realize non-manual discharging operation, which can effectively improve the injection production efficiency of plastic buckets.

[0004] However, when the above device is actually used, although it can accurately perform plastic molding, it can move under the action of the adjustment mechanism after plastic molding. However, the final mold still needs to be manually taken out. Moreover, after the plastic bucket is molded, its own temperature is still relatively high and it needs to be cooled before it can be taken out. This method is not only cumbersome but also affects the plastic molding efficiency of the plastic bucket and the production.

Detailed implementation manners

[0028] Now, the present invention will be further described in detail with reference to the accompanying drawings.

[0029] Please refer to Figures 1-7 As shown in the figure, in this embodiment, an injection molding device for plastic bucket processing is provided, which includes a processing table 1. Two adjusting frames 2 are arranged on the upper side of the processing table 1. A support frame 3 is arranged on the upper side of the processing table 1. An injection molding mechanism is arranged inside the support frame 3. A mold frame 4 is arranged on the upper side of the processing table 1. And a moving mechanism matching with the mold frame 4 is arranged in each of the two adjusting frames 2. A demolding groove corresponding to the mold frame 4 is arranged on the upper side of the processing table 1;

[0030] One side of the moving mechanism is provided with a servo motor 5. An inserting rod 6 is arranged on one side of the servo motor 5. An inserting block 7 matching with the inserting rod 6 is arranged on one side of the mold frame 4. Corresponding fixing holes 8 are arranged on both the inserting rod 6 and the inserting block 7. A fixing screw 9 corresponding to the fixing hole 8 is arranged on the upper side of the inserting block 8. Two interconnected water tanks 10 are respectively arranged on both sides of the processing table 1. A circulating cooling mechanism matching with the mold frame 4 is arranged on the water tank 10. A mold base 11 is arranged inside the mold frame 4. An injection molding groove 12 is arranged between the mold base 11 and the mold frame 4. A plurality of demolding parts are arranged inside the injection molding groove 12.

[0031] One application of this embodiment is as follows: When in use, first move the mold base 11 in the mold frame 4 to the lower side of the support frame 3 as needed, and then start the injection molding mechanism to perform injection molding on it. After the injection molding is completed, the moving mechanism can be started again to drive the mold frame 4 to move to the demolding groove. When the mold frame 4 moves, the circulating cooling mechanism can be started synchronously to accelerate the cooling of the injection mold. Then, start the servo motor 5, which can drive the insertion rod 6 to rotate. The rotation of the insertion rod 6 can drive the mold frame 4 and the mold base 11 to rotate on the demolding groove. After rotating 180 degrees, demolding can be performed with the cooperation of the demolding member, so that the plastic bucket after demolding is discharged from the demolding groove, facilitating the workers to collect it. After that, drive the servo motor 5 and the moving mechanism again, and reverse the above steps to complete the plastic mold of the next plastic bucket. Then, the connection between the insertion rod 6 and the insertion block 7 can be based on the fixing screw 9, so as to facilitate the replacement of different mold frames 4 and mold bases 11, enabling the equipment to perform injection molding on plastic buckets of different sizes.

[0032] Through the provided demolding member, the injection-molded mold in the mold frame 4 can be demolded. Driven by the servo motor 5, the mold frame 4 moved to above the demolding groove can be flipped by the insertion rod 6. With the combined use of the water tank 10 and the circulating cooling mechanism, it is convenient to cool the plastic bucket injection-molded on the mold base 11, accelerating the molding speed of the mold, so that the demolding member can better complete the demolding of the mold, avoiding the step of manual demolding after plastic molding, reducing the labor intensity of the workers, and at the same time, the mold can be directly fed and demolded through the demolding groove, further improving the demolding efficiency after the injection molding of the mold. With the setting of the fixing screw 9, the mold base 11 in the mold frame 4 can be separated from the insertion rod 6, facilitating the replacement of different mold bases 11 to perform injection molding on plastic buckets of different sizes, improving the injection molding range and applicability of the equipment for plastic buckets.

By providing the arc-shaped slider 14, when the mold base 11 is demolded and flipped, the arc-shaped slider 14 can move relying on its own gravity to facilitate the demolding of the plastic bucket formed on the mold base 13. And the arc-shaped slider 14 is arranged in contact with the surface of the mold base 11, so that the arc-shaped slider 14 can reduce the damage to the edge of the plastic bucket during demolding, improving the quality of the plastic bucket during demolding.

[0034] As Figures 1-4As shown in the figure, the circulating cooling mechanism of this embodiment includes telescopic hoses 16 respectively arranged on two water tanks 10, and an annular through groove 17 opened in the mold base 11.
