[0001] This utility model relates to the field of cleaning device technology, specifically to a multi-station injection mold cleaning device. Background Technology

[0002] In the production process of plastic products, injection molds are key components that determine the quality of product molding, and their cleanliness directly affects product precision, surface finish, and production continuity. For example, in the tire vulcanization process, rubber material comes into close contact with the mold surface under high temperature and pressure. Vulcanized rubber residues, antioxidants, plasticizers, and other substances adhere firmly to the surface of the tire mold and into the tread gaps. Currently, traditional tire mold cleaning methods mainly include manual scrubbing, sandblasting, and chemical cleaning.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0036] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0037] In some embodiments, please refer to Figures 1-11 in the accompanying drawings of the specification. A multi-station injection mold cleaning device includes a device body 1, a laser cleaning mechanism 2 and an airflow regulating component 3.

The bracket 211 is fixedly installed on the outer side of the upper end of the outer casing 12. The electric cylinder 212 and the motor 216 are both fixedly installed on the upper end of the bracket 211. The output end of the electric cylinder 212 is rotatably connected to the spline shaft 215. The spline sleeve 214 is rotatably connected to the lower end of the bracket 211 and is slidably connected to the spline shaft 215. The output end of the motor 216 is drivenly connected to the spline sleeve 214 through the pulley assembly 213.

[0046] The spline shaft 215 is connected to the cleaning assembly 22.

[0047] The cleaning assembly 22 includes a dust cover 221, a linear module slide 222, a laser cleaner 223, an infrared sensor 224, a limiting rod 225, and a positioning block 226. The middle part of the dust cover 221 is rotatably connected to the lower end of the spline shaft 215. The upper end of the limiting rod 225 is fixedly connected to the spline shaft 215, and the lower end of the limiting rod 225 is inserted into the limiting groove 17. The linear module slide 222 is fixedly installed on the upper end of the dust cover 221. The output end of the linear module slide 222 is fixedly connected to the laser cleaner 223. The front end of the laser cleaner 223 is fixedly connected to the infrared sensor 224. An opening groove is opened on the top of the dust cover 221. The positioning block 226 is fixedly installed on the side wall of the dust cover 221 and is inserted into the positioning groove 18. The lower end of the dust cover 221 is inserted into the receiving groove 19.

[0048] The laser cleaner 223 uses existing mature technology.

[0049] The limiting rod 225 is connected to the locking assembly 23, and the opening slot is connected to the airflow regulating assembly 3.

[0050] The locking assembly 23 includes a first spring 231, a limiting block 232, a push rod 233, a second spring 234, a slider 235, and a locking block 236. Multiple push rods 233, second springs 234, sliders 235, and locking blocks 236 are provided and are evenly spaced within the limiting groove 17. One end of the first spring 231 is fixedly installed at the bottom of the limiting groove 17, and the other end is fixedly connected to the bottom of the limiting block 232. The push rod 233 is slidably connected to a groove inside the limiting groove 17, with one end fixedly connected to the slider 235 and the other end fixedly connected to the locking block 236.

[0051] In use, the mold is placed on the rotary table 16, and the horizontal rotator 14 is activated, causing the mold on the rotary table 16 to rotate to the cleaning station. The electric cylinder 212 is then activated, driving the spline shaft 215 downwards. This causes the spline shaft 215 to move the dust cover 221 downwards. The dust cover 221 then moves the limiting rod 225 into the receiving groove 19, and the positioning block 226 into the positioning groove 18, locking the dust cover 221. Simultaneously, the limiting rod 225 inserts into the limiting groove 17 and continues to move downwards, positioning the limiting block 232 in the limiting groove 17. When pressed downwards, the limiting block 232 pushes the slider 235 to push the push rod 233 outwards, thereby locking the mold through the locking block 236. After locking, the motor 216 starts, and the motor 216 drives the spline sleeve 214 to rotate through the belt pulley assembly 213. The spline sleeve 214 drives the spline shaft 215 to rotate, the spline shaft 215 drives the limiting rod 225 to rotate, and the limiting rod 225 drives the rotary table 16 to rotate. The rotary table 16 thus drives the mold to rotate, and the laser cleaner 223 moves on the linear module slide 222 to clean different positions of the mold.

[0052] This utility model uses a horizontal rotator 14 to drive the mold into position, an electric cylinder 212 to drive a spline shaft 215 to achieve precise positioning and locking of the dust cover 221 with the mold, a motor 216 to drive the mold to rotate via a pulley assembly 213, and in conjunction with the movement of the laser cleaner 223 on the linear module slide 222, to achieve efficient, precise and stable cleaning of the mold in multiple directions.

[0053] In some embodiments, as shown in Figures 9-11, as a preferred embodiment of the present invention, the airflow regulating component 3 includes a motor 31, a gear 32, a transmission gear ring 33, a rotating ring 34, a sliding plate 35, a mounting ring 36, a sliding groove 37, a protrusion 38, and a connecting cylinder 39. The motor 31 is fixedly mounted on the outer end of the connecting cylinder 39, and the output end of the motor 31 is fixedly connected to the gear 32. The rotating ring 34 is slidably connected to the inner wall of the connecting cylinder 39. A through groove is provided in the middle of the connecting cylinder 39, and the transmission gear ring 33 is fixedly connected to the rotating ring 34 through the through groove. The inner wall of the transmission gear ring 33... The end is slidably connected to the outer end of the connecting cylinder 39, the gear 32 is meshed with the transmission gear ring 33, there are multiple sliding plates 35, and the lower ends of the multiple sliding plates 35 are slidably connected to the rotating ring 34, and the upper ends of the multiple sliding plates 35 are slidably connected to the mounting ring 36.

[0054] When this utility model is in use, the motor 31 starts, the motor 31 drives the gear 32 to rotate, the gear 32 drives the transmission gear ring 33 to rotate, the transmission gear ring 33 drives the rotating ring 34 to rotate, the rotating ring 34 drives the slide groove 37 to rotate, thereby causing the protrusion 38 to move in the slide groove 37, the protrusion 38 drives the slide plate 35 to slide on the mounting ring 36, thereby changing the opening and closing degree of multiple slide plates 35, thereby changing the cross-sectional area of ​​the airflow channel;

[0055] Infrared sensor 224 detects impurities in the mold, causing airflow adjustment component 3 to adjust the size of the air vents. When there is a lot of dirt, more impurities are generated, requiring a larger opening so that the vacuum cleaner can more efficiently suck up the impurities to ensure good vacuuming effect and prevent impurities from accumulating or overflowing in the dust cover 221. When the amount of impurities generated is small, the opening can be appropriately reduced to make the suction of the vacuum cleaner more concentrated, which can also effectively collect impurities and save energy.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
