[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The embodiment of the present application discloses a waste cleaning mechanism for an injection molding machine. Figure 1-3 A waste cleaning mechanism for an injection molding machine includes an injection molding machine 1 and a feeding assembly 2. When in use, the feeding assembly 2 needs to be inserted into the interior of the injection molding machine 1, and the heating unit on the outer side of the cylinder wall of the injection molding machine 1 is started to soften the waste on the inner wall to facilitate subsequent cleaning. The feeding assembly 2 includes a screw rod 201 installed in the injection molding machine 1, and a movable frame 202 is slidably sleeved on the screw rod 201, and the movable frame 202 can move linearly along the X-axis (the axis of the cylinder wall). The end of the movable frame 202 A cleaning component 3 is connected, and the cleaning component 3 includes a sleeve 301 installed on the movable frame 202. The sleeve 301 can rotate around the axis of the upper cylinder wall of the injection molding machine 1. Several guide plates 303 are circumferentially installed on the outer side of the sleeve 301. A telescopic cylinder 305 is installed on the guide plate 303, and several telescopic cylinders 305 are installed between the guide plate 303 and the sleeve 301. By controlling the extension and contraction of the telescopic cylinder 305, the position of the guide plate 303 relative to the sleeve 301 is adjusted to achieve cleaning radius adjustment.

[0020] Reference Figure 2 The end of the spiral rod 201 is connected to a driving assembly 4, which includes a support plate 401 installed at the end of the spiral rod 201. Two threaded rods 203 are installed on the outer side of the spiral rod 201 on the support plate 401, and the end of one of the threaded rods 203 is connected to a driving motor 402. The two threaded rods 203 are connected through a synchronous transmission unit. The synchronous transmission unit can adopt a chain transmission unit, a belt transmission unit, a transmission gear set, etc. as needed. In this solution, a chain transmission unit is selected, and the two threaded rods 203 are driven to rotate by the driving motor 402, so that the movable frame 202 moves.

[0021] Reference Figure 3 The movable frame 202 includes a connecting ring 2021 that is slidably mounted on the spiral rod 201. The connecting ring 2021 is threadedly connected to the two threaded rods 203. The end of the connecting ring 2021 is rotatably mounted on the support frame 2022. The support frame 2022 is fixedly connected to the sleeve 301, so that the sleeve 301 can rotate relative to the connecting ring 2021.

[0022] Reference Figure 3 The spiral rod 201 is sleeved with a rotating ring 302, which is fixedly mounted on the inner side of the sleeve 301. A storage chamber for storing fluid is opened in the side wall of the sleeve 301. The storage chamber is pre-stored with hydraulic oil. The pressurizing assembly 5 includes a piston 502 slidably mounted in the storage chamber. A screw rod 501 is rotatably mounted on one side of the piston 502. The end of the screw rod 501 is threaded through the sleeve 301.

[0023] A diversion channel is provided on the guide plate 303, and the telescopic cylinder 305 is composed of a piston rod and a piston cylinder. The connection between the piston rod and the piston cylinder is sealed with a sealing structure to prevent leakage of hydraulic oil. The piston cylinders are connected to the diversion channel. A connecting hole is provided in the middle of the piston rod on the side of the sleeve 301 away from the screw 501. The connecting hole is connected with the diversion channel and the storage chamber. By adjusting the relative position of the piston 502, the hydraulic oil can be pushed into the telescopic cylinder 305 or drawn out from the telescopic cylinder 305, thereby changing the oil pressure in the telescopic cylinder 305, realizing the telescopic adjustment of the telescopic cylinder 305, and changing the rotation radius of the overall scraper 304.

[0024] The implementation principle of the waste cleaning mechanism of an injection molding machine in the embodiment of the present application is as follows:

[0025] First, the nozzle and the screw of the injection molding machine body 1 are removed, and the heating unit on the injection molding machine body 1 is started to soften the waste material on the inner wall.

[0026] Then, insert the screw rod 201 into the injection molding machine body 1, and adjust the position of the piston 502 by turning the screw rod 501 to push the hydraulic oil in the storage chamber into the telescopic cylinder 305, increase the internal oil pressure, and extend the telescopic cylinder 305, thereby pushing the scraper 304 to expand outward, increasing the cleaning radius and making it fit the cylinder wall.

[0027] Then, the drive motor 402 is started, and the motor drives the two threaded rods 203 to rotate synchronously through the chain transmission unit, thereby driving the connection to move linearly along the cylinder wall. At the same time, the sleeve 301 can rotate around the axis of the injection molding machine cylinder wall, and the waste is preliminarily cleaned through the rotation action.

[0028] The scraper 304 is in close contact with the inner wall of the injection molding machine under the action of rotation, and effectively removes the waste material attached thereto.

[0029] After the cleaning is completed, the driving motor 402 is operated in reverse to make the movable frame 202 and the cleaning assembly 3 withdraw from the injection molding machine body 1 along the X-axis direction.

[0030] At the same time, the oil pressure is adjusted by the pressure component 5 so that the telescopic cylinder 305 is retracted back to the initial position and the scraper 304 is reset.

[0031] Turn off the heating unit and complete the cleaning process.

[0032] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
