[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figure 1 - Figure 5 As shown, the utility model provides a technical solution: an injection molding device for producing trash cans, including a mounting plate 1, a lower mold base 2 is mounted on the top of the mounting plate 1, an upper mold base 3 is arranged on the top of the lower mold base 2, an injection port 4 is opened on the top of the upper mold base 3, both ends of one side of the lower mold base 2 are fixedly connected with a fixed shell 5, both ends of the inner side of the mounting plate 1 are fixedly connected with a shell 6, a rotating rod 7 is rotatably connected to the inside of the shell 6, one end of the rotating rod 7 located inside the shell 6 is fixedly connected to a limiting plate 8, both sides of the inside of the shell 6 are slidably connected with a moving plate 9, and one side of the moving plate 9 is fixedly connected to the moving plate 9. A clamping block 10 is fixedly connected, and clamping grooves 11 are provided on both sides of the fixed shell 5. The interior of the clamping groove 11 is slidably connected to the clamping block 10. The limit plate 8 is driven to rotate ninety degrees by rotating the rotating rod 7, and no longer blocks the movable plate 9. At this time, the movable plate 9 is pushed by the rebound force of the first spring 14 to drive the clamping block 10 to disengage from the interior of the clamping groove 11, thereby releasing the fixation of the fixed shell 5. By arranging a rubber pad between the mounting plate 1 and the lower die base 2, it is convenient to take out the lower die base 2 by squeezing the rubber pad, thereby realizing the replacement of the lower die base 2. The operation is simple and convenient, the structure is stable, and the production efficiency is improved.

[0024] Reference Figure 1 - Figure 3 As shown, in this embodiment: both sides of the shell 6 are fixedly connected with the limiting rod 12, the surface of the movable plate 9 is provided with a limiting groove 13, the inside of the limiting groove 13 is slidably connected with the surface of the limiting rod 12, and by setting the structure of the limiting rod 12 and the limiting groove 13, the movement of the movable plate 9 can be kept stable and tilting can be avoided.

[0025] Reference Figure 1 - Figure 3As shown, in this embodiment: the first spring 14 is fixedly connected to both sides of the shell 6, and the other end of the first spring 14 is fixedly connected to the movable plate 9. By setting the first spring 14, the action force of the first spring 14 is utilized to assist the movement of the movable plate 9.

[0026] Reference Figure 1 - Figure 3 As shown, in this embodiment: the difference between the maximum diameter and the minimum diameter of the limiting plate 8 is greater than the distance that the block 10 is inserted into the slot 11. Through the above arrangement, when the limiting plate 8 rotates ninety degrees, it no longer blocks the movable plate 9. At this time, the moving distance of the movable plate 9 can enable the block 10 to escape from the inside of the slot 11.

[0027] Reference Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment: the interior of the rotating rod 7 is slidably connected to a sliding rod 15, and one end of the sliding rod 15 located on the outside of the rotating rod 7 is fixedly connected to a knob 16, and one side of the knob 16 is fixedly connected to an insertion rod 17, and a slot 18 is provided on the top of the shell 6, and the interior of the slot 18 is sleeved with the insertion rod 17. The sliding rod 15 is driven upward by pulling the knob 16 to disengage the insertion rod 17 from the interior of the slot 18, and the knob 16 is turned to make the rotating rod 7 drive the limit plate 8 to rotate. At the same time, when it is necessary to fix the knob 16, the knob 16 can be rotated to make the insertion rod 17 be located at the same horizontal plane as the slot 18 and inserted into the interior of the slot 18.

[0028] Reference Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment: both ends of the interior of the rotating rod 7 are provided with a slide groove 19, and a slider 20 is slidably connected to the interior of the slide groove 19, and the other end of the slider 20 is fixedly connected to the slide rod 15. By setting the structure of the slide groove 19 and the slider 20, the moving trajectory of the slide rod 15 can be restricted to prevent the user from using too much force when pulling the knob 16, causing the slide rod 15 to escape from the interior of the rotating rod 7.

[0029] Reference Figure 1 , Figure 4 and Figure 5 As shown, in the present embodiment: a second spring 21 is fixedly connected inside the rotating rod 7, and the other end of the second spring 21 is fixedly connected to the sliding rod 15. By providing the second spring 21, when the user pulls the knob 16 to drive the sliding rod 15 to move upward, the second spring 21 begins to stretch. When the knob 16 needs to be fixed, the rebound force of the second spring 21 is utilized to drive the sliding rod 15 so that the knob 16 pushes the insertion rod 17 to be inserted into the interior of the slot 18, thereby greatly saving manpower.

[0030] Reference Figure 1 and Figure 2As shown, in this embodiment: cooling channels 22 are provided on both sides of the upper mold base 3, a connecting pipe 23 is connected to one side of the cooling channel 22, and the connecting pipe 23 passes through the interior of the upper mold base 3, and an air pump 24 is installed at the other end of the connecting pipe 23. By utilizing the coordinated use of the cooling channel 22, the connecting pipe 23 and the air pump 24, the trash can can be cooled after the injection molding is completed to avoid the problem of bubbles.

[0031] Working principle: the user drives the limit plate 8 to rotate ninety degrees by turning the rotating rod 7, and no longer blocks the moving plate 9. At this time, the moving plate 9 is pushed by the resilience of the first spring 14 to drive the card block 10 to disengage from the interior of the card slot 11, thereby releasing the fixation of the fixed shell 5. By arranging a rubber pad between the mounting plate 1 and the lower die seat 2, it is convenient to take out the lower die seat 2 by squeezing the rubber pad, thereby realizing the replacement of the lower die seat 2. The operation is simple and convenient, the structure is stable, and the production is improved. By setting the structure of the limit rod 12 and the limit slot 13, the movement of the moving plate 9 can be kept stable to avoid tilting. By setting the first spring 14, the action force of the first spring 14 is utilized to assist the movement of the moving plate 9. Through the above-mentioned arrangement, when 8 rotates ninety degrees, it no longer blocks the moving plate 9. At this time, the moving distance of the moving plate 9 can make the card block 10 disengage from the interior of the card slot 11. By pulling the knob 16, the sliding rod 15 is driven to move upward, so that the insertion rod 1 7 is disengaged from the interior of the slot 18, and the knob 16 is turned to make the rotating rod 7 drive the limiting plate 8 to rotate. At the same time, when the knob 16 needs to be fixed, the knob 16 can be rotated to make the insertion rod 17 located at the same horizontal plane of the slot 18 and inserted into the interior of the slot 18. By setting the structure of the slide groove 19 and the slider 20, the movement trajectory of the slide rod 15 can be restricted to prevent the user from using too much force when pulling the knob 16 and causing the slide rod 15 to disengage from the interior of the rotating rod 7. By setting the second spring 21, when the user pulls the knob 16 to drive the slide rod 15 to move upward, the second spring 21 begins to stretch. When the knob 16 needs to be fixed, the rebound force of the second spring 21 is used to drive the slide rod 15 so that the knob 16 pushes the insertion rod 17 to insert into the interior of the slot 18, which greatly saves manpower. By using the cooperation between the cooling channel 22, the connecting pipe 23 and the vacuum pump 24, the trash can can be cooled after the injection molding is completed to avoid the problem of bubbles.
