[0025] like Figures 1 to 5 As shown, the utility model is a highly efficient cleaning device for plastic molds, comprising: a cleaning box 1, a cleaning mechanism for cleaning the plastic molds;

[0026] The cleaning mechanism includes: a water tank 22 fixedly mounted at the bottom of the inner cavity of the cleaning box 1, a water pump 23 fixedly mounted on the outside of the cleaning box 1, a water inlet pipe plugged between the water tank 22 and the water pump 23, a movable plate 18 hinged at the top of the inner cavity of the cleaning box 1, a return spring 20 fixedly mounted between the movable plate 18 and the inner wall of the cleaning box 1, a diverter plate 19 fixedly mounted at the bottom of the movable plate 18, a water spray head plugged at the bottom of the diverter plate 19, a telescopic hose plugged between the water pump 23 and the diverter plate 19, a swinging component for driving the swinging of the movable plate 18, and a cleaning component for auxiliary cleaning of the plastic mold.

[0027] The swing assembly comprises: a first U-shaped plate fixedly mounted on the top of the inner cavity of the cleaning box 1, a linkage rod 16 penetrating and mounted on the side wall of the first U-shaped plate, a linkage plate 15 fixedly mounted on one end of the linkage rod 16, a linkage spring 17 sleeved on the outer edge of the linkage rod 16, and a power unit driving the linkage plate 15 to move, the power unit comprises: a second U-shaped plate fixedly mounted on the outer side of the cleaning box 1, a motor 2 fixedly mounted on the inner wall of the second U-shaped plate, a rotating shaft fixedly mounted on the power output shaft of the motor 2, a driving bevel gear 9 fixedly sleeved on the outer edge of the rotating shaft, a linkage shaft rotatably mounted on the side wall of the second U-shaped plate, a driven bevel gear 10 and a driving pulley 11 respectively fixedly mounted on both ends of the linkage shaft, a transmission shaft rotatably mounted on the top of the cleaning box 1, a driven pulley 13 and a cam 14 respectively fixedly mounted on both ends of the rotating shaft, the driving bevel gear 9 and the driven bevel gear 10 are meshed with each other, and a linkage belt 12 is installed for transmission between the driving pulley 11 and the driven pulley 13;

[0028] When the plastic mold is fixed, the motor 2 and the water pump 23 are started, and the water in the water tank 22 is transported to the inner cavities of the two diverter plates 19 through the water pump 23, and the plastic mold can be sprayed and cleaned through a plurality of water spray heads at the bottom of the diverter plate 19;

[0029] At the same time, the power output shaft of the motor 2 drives the rotating shaft to rotate, and the rotating shaft is rotatably mounted on the wall of the cleaning box 1. The rotating shaft drives the active bevel gear 9, the active gear 6 and the clamping plate 4 to rotate. The rotation of the clamping plate 4 can drive the plastic mold to rotate, so that the plastic mold is fully contacted with the water flow for cleaning, thereby improving the efficiency of plastic mold cleaning;

[0030] At this time, the driven bevel gear 10 is driven to rotate by the active bevel gear 9, the linkage shaft is driven to rotate by the driven bevel gear 10, the active pulley 11 is driven to rotate by the linkage shaft, the linkage belt 12 is driven to rotate by the active pulley 11, the driven pulley 13 is driven to rotate by the linkage belt 12, the transmission shaft is driven to rotate by the driven pulley 13, and the cam 14 is driven to rotate by the transmission shaft. When the cam 14 rotates and contacts the two linkage plates 15 respectively, the linkage plate 15 can be driven to move, and the linkage rod 16 can be driven to move through the linkage plate 15, and the linkage spring 17 can be compressed. The linkage spring 17 is fixedly installed between the linkage plate 15 and the inner wall of the first U-shaped plate. Through the movement of the linkage rod 16, it can contact the movable plate 18 and drive the movable plate 18 to deflect. The movable plate 18 drives the diverter plate 19 to deflect, and the movable plate 18 drives the reset spring 20 to compress. When the cam 14 rotates and separates from the linkage plate 15, the elastic force of the linkage spring 17 can drive the linkage plate 15 to reset, and the linkage plate 15 drives the linkage rod 16 to reset, so that the linkage rod 16 separates the movable plate 18. At this time, the elastic force of the reset spring 20 can drive the movable plate 18 to reset, and the diverter plate 19 is reset by the movable plate 18. Through the continuous rotation of the cam 14, the diverter plate 19 can drive several water spray heads to swing, thereby increasing the spray range, facilitating uniform and comprehensive cleaning of the surface of the plastic mold, and the cleaning time is short and the cleaning is complete, further improving the cleaning effect and cleaning efficiency of the plastic mold.

[0031] The cleaning assembly includes: a driving gear 6 fixedly sleeved on the outer edge of the rotating shaft, a long shaft rotatably mounted on the side wall of the cleaning box 1, a driven gear 7 fixedly sleeved on the outer edge of the long shaft and a cleaning cylinder 8, and the driving gear 6 and the driven gear 7 are meshed with each other;

[0032] The driving gear 6 drives the driven gear 7 to rotate, the driven gear 7 drives the long shaft to rotate, and the driven gear 7 drives the cleaning cylinder 8 to rotate. The rotation of the cleaning cylinder 8 can assist in cleaning the plastic mold, so that the plastic mold is fully cleaned, further improving the cleaning effect and cleaning efficiency of the plastic mold.

[0033] A rotating rod is rotatably mounted on the inner wall of the cleaning box 1, an electric telescopic rod 3 is fixedly mounted on one end of the rotating rod, a clamping plate 4 is fixedly mounted on one end of the electric telescopic rod 3 close to the rotating shaft, and an anti-slip pad 5 is fixedly mounted on one side of the clamping plate 4;

[0034] The plastic mold is placed between the two clamping plates 4. At this time, the electric telescopic rod 3 is started, and the power output shaft of the electric telescopic rod 3 drives the adjacent clamping plates 4 to extrude the plastic mold. The two clamping plates 4 cooperate with each other to facilitate clamping and fixing the plastic mold. The two anti-skid pads 5 are provided to increase the friction between the two clamping plates 4 and the plastic mold, thereby improving the clamping stability. The anti-skid pads 5 can be latex pads. In the process of the two clamping plates 4 clamping the plastic mold, the plastic mold can be buffered and protected to avoid contact between the two clamping plates 4 and the plastic mold, which may cause damage to the plastic mold.

[0035] A filter screen 21 is fixedly mounted on the inner wall of the cleaning box 1, and a movable door is hinged on the side wall of the cleaning box 1;

[0036] The cleaned sewage flows into the inner cavity of the water tank 22 through the mesh of the filter 21 for collection. The filter 21 can filter the impurities in the sewage. The filtered water flows into the inner cavity of the water tank 22 and is sucked in by the water pump 23 for reuse, thus realizing the recycling of water resources, saving water resources and improving the environmental protection of the device.

[0037] After cleaning is completed, the impurities on the top of the filter screen 21 can be cleaned by opening the movable door, and the clamping plate 4 can be driven to move by starting the electric telescopic rod 3 so that the clamping plate 4 has no clamping effect on the plastic mold, and the plastic mold can be easily disassembled and removed.

[0038] Working principle: When in use, by starting the motor 2 and the water pump 23, the water in the water tank 22 can be transported to the inner cavity of the two diverter plates 19 through the water pump 23, and the plastic mold can be sprayed with water for cleaning through a plurality of water spray heads at the bottom of the diverter plate 19. The rotation of the motor 2 can drive the plastic mold to rotate, so that the plastic mold is fully in contact with the water flow for cleaning, thereby improving the cleaning efficiency of the plastic mold. At the same time, it can drive a plurality of water spray heads to swing, thereby increasing the spray range, facilitating uniform and comprehensive cleaning of the surface of the plastic mold, and the cleaning time is short and the cleaning is complete, further improving the cleaning effect and cleaning efficiency of the plastic mold.
