The baffle deflects the products into the range of action of the guiding plate. The power device acts, causing the roller shaft inside the rotating groove to rotate, ensuring the smooth movement of the injection-molded products. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] A lifting hole 413 is penetratingly formed in the cross plate of the support frame 3; a protective cover 414 is arranged inside the lifting hole 413; a structure hole 415 is penetratingly formed at the top of the protective cover 414; a connecting cylinder 416 is installed at the top of the protective cover 414 at the top of the structure hole 415; the connecting cylinder 416 communicates with the structure hole 415; an air extraction pipe 417 is installed on the connecting cylinder 416; a fan 418 is installed on the air extraction pipe 417; a bracket 409 is installed at the bottom of the support frame 3; an air supply device 410 is arranged on the bracket 409; a cooling mechanism 411 is installed on the air supply device 410; the bottom end of the connecting pipe 408 is connected to the cooling mechanism 411; an air pump 412 is installed on the connecting pipe 408; fixing plates 419 are symmetrically and fixedly connected to the bottoms of the two side plates of the fixing frame 404; connecting plates 420 are fixedly connected to the tops of the two side plates of the protective cover 414; a screw rod 421 is installed on the connecting plate 420; the bottom of the screw rod 421 is connected to the top of the fixing plate 419; the top of the screw rod 421 passes through the plate body of the connecting plate 420 and extends out and is installed with a rotating knob 422; the height of the screw rod 421 is greater than the height of the protective cover 414;

[0025] During operation, when some plastic products are assisted in production by an injection molding machine, the formed products need to be cooled to ensure the rapid production of the products; when the above plastic injection molding machine cooling device is in use, the products that are not fully cooled are likely to come into contact with the dust in the external space, resulting in the dust in the cooling space being easily adhered to the products, affecting the quality of the injection molded products, and when the existing injection molding cooling device is in use, it is prone to clogging, affecting the continuous progress of the cooling streamline.

[0026] Please refer to Figure 2 、 5As shown in the figure, a connecting frame 501 is fixedly connected to the end of the top plate of the fixing frame 404 away from the injection molding machine body 1; a rotating shaft 502 is installed on the connecting frame 501; a dial plate 503 is installed on the rotating shaft 502; a driving mechanism 504 is installed on the side surface of the connecting frame 501; the driving mechanism 504 acts on the rotating shaft 502; the rotation trajectory of the dial plate 503 does not contact the body of the support frame 3; a fixing rod 505 is installed at the end of the body of the support frame 3 close to the connecting frame 501; a guide plate 506 is installed on the fixing rod 505; a rotating groove 507 is opened at the top of the guide plate 506; a rolling shaft 508 is installed inside the rotating groove 507; a power device 509 is installed on the side surface of the guide plate 506; the power device 509 acts on the rolling shaft 508;

[0027] During operation, with the movement of the conveyor belt 401, the driving mechanism 504 on the connecting frame 501 acts, and the rotating shaft 502 drives the dial plate 503 to rotate, avoiding the injection molding products from being blocked in the cooling structure. The dial plate 503 deflects the products into the action range of the guide plate 506. The power device 509 acts, and the rolling shaft 508 inside the rotating groove 507 rotates, ensuring the smooth movement of the injection molding products.

[0028] Working principle: When some plastic products are assisted in production using an injection molding machine, it is necessary to cool the molded products to ensure rapid production of the products. When the above-mentioned cooling device of the plastic injection molding machine is in use, the products that are not fully cooled are prone to contact with the dust in the external space, resulting in the dust in the cooling space being easily adhered to the products, affecting the quality of the injection-molded products. Moreover, when the existing injection molding cooling device is in use, it is prone to clogging, affecting the continuous progress of the cooling streamline. After the injection molding die 2 injects and forms the products, the products fall on the top of the conveyor belt 401. According to the size of the products, a rotational force is applied to the rotary knob 422, and the screw 421 on the top of the fixed plate 419 rotates. The connecting plate 420 drives the protective cover 414 to move along the lifting hole 413 to a suitable position. Subsequently, the air pump 412 on the connecting pipe 408 is started, and the air supply device 410 sends the gas into the cooling mechanism 411. Under the action of the cooling mechanism 411, the gas is cooled and enters the blow pipe 406, and then blows towards the products on the top of the conveyor belt 401 through the air nozzle 407. Moreover, the fan 418 operates, and suction is generated at the position of the opening of the structural hole 415. The gas that has absorbed heat enters the connecting cylinder 416 through the structural hole 415 and is discharged to the outside through the suction pipe 417, achieving rapid cooling of the products, avoiding long-term contact between the products and the external environment, and ensuring the cleanliness of the products. As the conveyor belt 401 moves, the driving mechanism 504 on the connecting frame 501 acts, and the rotating shaft 502 drives the baffle 503 to rotate, preventing the injection-molded products from clogging in the cooling structure. The baffle 503 deflects the products into the range of action of the guide plate 506. The power device 509 acts, and the roller shaft 508 inside the rotating groove 507 rotates, ensuring the smooth movement of the injection-molded products.
