All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1 to 4 This utility model provides a cleaning device for injection molding tanks on an injection molding machine, including a mounting frame 1. A controller 18 is fixedly mounted on the surface of the mounting frame 1. The controller 18 is electrically connected to an external power source through a wire. A mounting post 11 for mounting to an external injection molding machine housing is welded to the bottom end of the mounting frame 1. The surface of the mounting post 11 is provided with mounting holes.

[0026] It is worth noting that by setting the mounting post 11 and the mounting hole, the mounting bracket 1 can be firmly fixed.

[0027] The surface of the mounting bracket 1 is fitted with an injection molding machine feed pipe 2, and the bottom end of the injection molding machine feed pipe 2 is connected to the feed chamber of the external injection molding machine.

[0028] The top of the mounting bracket 1 is fixedly mounted with an injection molding tank 3, and the top of the injection molding tank 3 is fitted with a material supply pipe 12.

[0029] By setting up the feeding pipe 12, external raw materials can be added into the injection molding tank 3.

[0030] The bottom of the injection tank 3 corresponds to the upper opening of the injection molding machine feed pipe 2.

[0031] It is worth noting that when using the injection molding machine, the raw material inside the injection tank 3 enters the external injection molding machine through the injection molding machine feed pipe 2 for the injection molding machine to perform the injection molding action.

[0032] The injection molded tank 3 is equipped with a cleaning component inside.

[0033] The cleaning assembly includes a geared motor 13 fixedly mounted on the top of the injection molding tank 3. The output shaft of the geared motor 13 extends into the interior of the injection molding tank 3 and is fixedly mounted on a vertical shaft 14. An arm 15 is fixedly mounted on the surface of the vertical shaft 14. A scraper 16 is fixedly mounted on the end of the arm 15 away from the injection molding tank 3. The scraper 16 is adapted to the shape of the inner wall of the injection molding tank 3.

[0034] It is worth noting that by setting up a cleaning component, when it is necessary to clean the inside of the injection molding tank 3, the vertical shaft 14 is driven to rotate by the reduction motor 13. Under the support of the arm 15, the scraper 16 rubs against the inner wall of the injection molding tank 3 to achieve the purpose of scraping and cleaning the residue adhering to the inner wall of the injection molding tank 3.

[0035] The boom 15 includes a sleeve 1501 and a telescopic tube 1502.

The lower connecting ring sleeve 501 is adapted to the inner diameter of the injection molding machine feed pipe 2, and the upper connecting ring sleeve 503 is adapted to the outer diameter of the bottom end of the injection molding tank 3.

[0040] It is worth noting that by setting the slag receiving gap and connecting components, during normal use, the hydraulic rod 4 extends to drive the connecting ring seat 5 to move upward, keeping the injection tank 3 connected to the injection molding machine feed pipe 2, so as to ensure smooth feeding.

[0041] The slag receiving assembly includes two side plates 6 fixedly installed on the upper surface of the mounting frame 1. A reciprocating screw 7 is rotatably connected between the two side plates 6. A servo motor 8 for driving the reciprocating screw 7 to rotate is fixedly installed on the surface of the back side plate 6. A movable seat 9 is threadedly connected to the surface of the reciprocating screw 7. A slag receiving plate 10 is fixedly installed on the top of the movable seat 9. The position of the slag receiving plate 10 corresponds to the position of the slag receiving gap.

[0042] It is worth noting that by setting up a slag receiving component, before cleaning the inside of the injection molding tank 3, the hydraulic rod 4 is controlled to retract, causing the connecting ring seat 5 to move downward, so that the slag receiving gap is exposed. At this time, the servo motor 8 drives the reciprocating screw 7 to rotate, which can drive the slag receiving plate 10 to extend into the slag receiving gap and directly collect the slag cleaned from the inside of the injection molding tank 3. There is no need to run the injection molding machine to discharge the slag. It has the effects of convenient operation and energy saving.

[0043] A limiting slide rod 17 is fixedly installed between the two side plates 6, and the movable seat 9 is slidably connected to the surface of the limiting slide rod 17.
