Description

Technical Field

[0001] This utility model relates to the technical field of plastic bucket production equipment, specifically to a plastic bucket injection molding machine with an adjustment mechanism. Background Technology

[0002] Plastic drums, with their lightweight, corrosion resistance, low cost, and reusability, are widely used in numerous fields such as chemical, food, pharmaceutical, and agriculture. In the chemical industry, plastic drums are commonly used to store and transport various acidic and alkaline chemical reagents. For example, in the production of fine chemicals, PVC plastic drums can safely store highly corrosive liquids such as hydrochloric acid and sulfuric acid, effectively avoiding the risk of leakage caused by corrosion of metal containers. According to industry statistics, the chemical industry's annual demand for plastic drums reaches tens of millions. With the rise of e-commerce, the demand for plastic drums in logistics and transportation has also increased significantly, as their lightweight nature effectively reduces transportation costs. With the vigorous development of various industries, the market demand for plastic drums continues to grow, and the requirements for their specifications, shapes, and quality are becoming increasingly diverse and refined.

[0003] In existing technologies, traditional mold adjustment structures struggle to achieve rapid and precise positioning adjustments. For example, when producing large-capacity, irregularly shaped plastic buckets, traditional adjustment mechanisms cannot quickly and accurately adjust the mold position, leading to frequent downtime for adjustments and significantly reducing production efficiency. Furthermore, due to insufficient mold positioning accuracy, plastic buckets are prone to quality problems such as uneven wall thickness and barrel deformation during molding, resulting in low product qualification rates and increased production costs. Utility Model Content To overcome the above-mentioned defects, this utility model provides a plastic bucket injection molding machine with an adjustment mechanism, which solves the technical problem that the traditional mold adjustment structure in the prior art is difficult to achieve fast and accurate positioning adjustment, which leads to quality problems such as uneven wall thickness and barrel deformation during the molding process, resulting in low product qualification rate.

[0023] like Figures 1-3 As shown, it illustrates a plastic bucket injection molding machine with an adjustment mechanism according to one embodiment of the present invention. In some examples, a workbench 1 is provided with an adjustment component 2 at one end of the upper part of the workbench 1, and a bucket-retrieving mechanism 3 is provided at another end of the upper part of the workbench 1. A first slide rail 12 is provided on one side of the surface of the workbench 1, and a mold mounting platform 14 is fixedly installed at the center of the upper end of the workbench 1. The adjustment component 2 includes a first servo motor 21 and a moving frame 23. The first servo motor 21 is fixedly installed on the right end of the workbench 1. The bottom end of the moving frame 23 is slidably connected to the workbench 1 through the first slide rail 12. A second slide rail 26 is provided on one side surface of the moving frame 23. The moving frame 23 is slidably connected to the lifting seat 210 through the second slide rail 26.

[0024] The output shaft of the first servo motor 21 is fixedly connected to the first lead screw 22. The first lead screw 22 passes through the bottom end of the moving frame 23 and is threadedly connected to the moving frame 23. The front bottom end of the moving frame 23 is fixedly connected to the connecting block 24. The upper end of the connecting block 24 is threadedly connected to the threaded positioning post 25. The top end of the moving frame 23 is fixedly connected to the second servo motor 27. The output shaft of the second servo motor 27 is fixedly connected to the second lead screw 28. The second lead screw 28 passes through the lifting seat 210 and is threadedly connected to the lifting seat 210.

[0025] The first lead screw 22 is installed inside the first slide rail 12 and its two ends are rotatably connected to the worktable 1. The second lead screw 28 is installed inside the second slide rail 26 and its two ends are rotatably connected to the moving frame 23.

[0026] The adjustment assembly 2 also includes a slide bar 29, which is located inside the second slide rail 26 and is fixedly connected to the movable frame 23 at both ends. The slide bar 29 passes through the lifting seat 210 and is slidably connected to the lifting seat 210. The bottom end of the lifting seat 210 is fixedly connected to the upper mold 211.

[0027] The bottom of the workbench 1 is fixedly connected to a support leg 11, and a threaded positioning groove 13 is provided on a part of the surface of the workbench 1.

[0028] A lower mold 15 is fixedly installed on the upper end of the mold mounting platform 14. An electric push rod 16 is fixedly connected inside the lower mold 15. A push block 17 is fixedly connected to the top of the telescopic column of the electric push rod 16. The push block 17 is movably connected to the lower mold 15.

[0029] For example, such as Figure 4 As shown, the first servo motor 21 drives the first lead screw 22 to rotate, causing the moving frame 23 to move left and right above the worktable 1, thereby adjusting the horizontal position of the upper mold 211. The second servo motor 27 drives the second lead screw 28 to rotate, causing the lifting seat 210 to rise and fall, making the vertical height of the upper mold 211 adjustable. The height adjustment can adapt to the needs of products with different thicknesses, ensuring mold closing accuracy. The left and right position adjustment can accurately align the injection head, adapting to molds of different shapes, making the device adaptable to the production needs of plastic buckets of different specifications and shapes, improving production efficiency and the molding quality of plastic buckets. With the setting of the threaded positioning pin 25, after the position of the moving frame 23 is determined, the threaded positioning pin 25 can be rotated to rotate the threaded positioning pin 25 into the corresponding threaded positioning groove 13, limiting the position of the moving frame 23 and enhancing the stability of horizontal adjustment. The electric push rod 16 lifts the push block 17 from the top of the lower mold 15, thereby lifting the mold after molding and demolding the mold, enhancing demolding efficiency.

[0030] In some examples, by setting up the bucket-retrieving mechanism 3, the third servo motor 34 drives the bidirectional lead screw 35 to rotate, which drives the clamping plate 36 to move relative to the moving frame 23 within the range of the moving frame, clamping the mold after molding. With the help of the robotic arm 31, the finished plastic bucket is taken out from the upper end of the lower mold 15 and moved to the designated place. This increases the continuity of product production, avoids the waste of labor costs caused by manual product removal, and speeds up the production process.

[0031] The bucket retrieval mechanism 3 includes a robotic arm 31, which is fixedly installed on the upper end of the workbench 1, and the output end of the robotic arm 31 is fixedly connected to a mounting base 32.

[0032] A third slide rail 33 is provided on one side surface of the mounting base 32. The mounting base 32 is slidably connected to a clamping plate 36 through the third slide rail 33. A third servo motor 34 is fixedly connected to the top of the mounting base 32. A bidirectional lead screw 35 is fixedly connected to the output shaft of the third servo motor 34. The bidirectional lead screw 35 is installed inside the third slide rail 33 and its two ends are rotatably connected to the mounting base 32. The bidirectional lead screw 35 passes through the clamping plate 36 and is threadedly connected to the clamping plate 36. A rubber pad 37 is fixedly connected to the inner surface of the clamping plate 36.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
