[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] An automated plastic mold cleaning device, as shown in Figure Figure 4 As shown, it includes a push-pull mechanism 1, and a cleaning mechanism 2 is fixedly connected to the top of the push-pull mechanism 1;

[0028] The cleaning mechanism 2 includes a suction head 201, which is fixedly connected to the top of the push-pull mechanism 1. The top of the suction head 201 is connected with two groups of connecting pipes 202. The inner wall of each group of connecting pipes 202 is respectively installed with a group of fans 203. The inner wall of the connecting pipe 202 is sleeved with a mounting ring 204 located above the fan 203. The top of the mounting ring 204 is fixedly connected with a filter bag 205. The bottom end of the suction head 201 is provided with a suction nozzle 206. The push-pull mechanism 1 includes a sliding bin 101. The inner wall of the sliding bin 101 is rotatably connected with a threaded rod 102 extending to the outside of the sliding bin 101. The side wall of the sliding bin 101 is fixedly connected with a motor 104. The output end of the motor 104 is fixedly connected to the end of the threaded rod 102. The outer wall of the threaded rod 102 is threadedly connected with a sliding plate 103. The end of the sliding plate 103 is fixedly connected with the suction head 201.

[0029] The motor 104 drives the threaded rod 102 to rotate, so that the threaded rod 102 pushes the sliding plate 103 to move, and the sliding plate 103 drives the suction head 201 to move above the mold, and the fan 203 blows the airflow from the suction nozzle 206 into the suction head 201, and then the air passes through the filter bag 205 and is discharged, thereby sucking away the dust and debris on the mold, and the dust and debris are filtered out by the filter bag 205, so as to prevent the dust and debris from falling on the mold again. After cleaning is completed, the motor 104 drives the threaded rod 102 to rotate in the opposite direction, so that the threaded rod 102 pushes the sliding plate 103 to slide in the opposite direction and reset, thereby driving the suction head 201 to reset. After the suction head 201 is reset, the fan 203 stops rotating, so that the debris and dust inside the filter bag 205 fall out from the suction nozzle 206. After the cleaning device is installed, a trash can can be placed under the cleaning device to collect the debris and dust.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 The bottom end of the sliding bin 101 is fixedly connected with an adjustment mechanism 3, and the adjustment mechanism 3 includes a side plate 301, which is fixedly connected to the bottom end of the sliding bin 101, and a group of sliders 302 are fixedly connected on both sides of the side plate 301, and the outer wall of each group of sliders 302 is slidably connected with a group of mounting plates 303, and the side walls of the mounting plates 303 are fixedly connected with racks 304, and the inner wall of the slider 302 is rotatably connected with a rotating pin 305, and the rotating pin 305 is fixedly installed with a torsion spring at the contact position with the slider 302, and the bottom end of the rotating pin 305 extends to the outside of the slider 302, and one end of the rotating pin 305 located outside the slider 302 overlaps the outer wall of the rack 304, and the side wall of the rotating pin 305 is fixedly connected with a lever 306 extending to the outside of the slider 302, and the side wall of the slider 302 is provided with an opening that matches the running direction of the lever 306.

[0031] The mounting plate 303 is fixed to the injection molding machine table by using bolts, and then the lever 306 is pushed, and the lever 306 drives the rotating pin 305 to rotate, so that the rotating pin 305 is transferred into the slider 302, and the torsion spring is twisted. At this time, the rotating pin 305 is not in contact with the rack 304, and then the slider 302 is pushed upward or downward, so that the slider 302 drives the sliding bin 101 to rise and fall through the side plate 301, thereby changing the height of the suction head 201. After determining the height of the suction head 201, the lever 306 is released, so that the torsion spring drives the rotating pin 305 to reset. At this time, the rotating pin 305 is blocked by the rack 304, so the weight of the push-pull mechanism 1 and the cleaning mechanism 2 will not push the slider 302 down, thereby fixing the height of the suction head 201.

[0032] When in use, the fan 203 rotates to drive the air flow to the inside of the suction head 201, and the suction head 201 is moved close to the mold, so that the air flow brings the debris and dust on the mold into the suction head 201, and then the debris is filtered out by the filter bag 205, avoiding the problem of the debris and dust blown up by the high-pressure gas falling onto the mold again after falling onto the mold surface. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
