Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1-5 This utility model provides an injection mold for easy cleaning of residue, including a mold body 1; a servo motor 11 is provided on the side wall of the mold body 1; a pair of brackets 12 are fixedly connected to the side wall of the servo motor 11; the brackets 12 are symmetrically arranged on both sides of the servo motor 11 and have the same structure; a screw 13 is threadedly connected to the side wall of the bracket 12; the screw 13 penetrates the wall of the bracket 12 and is threadedly connected to it; a fixing block 14 is fixedly connected to the end of the screw 13; a pair of telescopic rods 15 are fixedly connected to the side wall of the servo motor 11; the telescopic rods 15 are symmetrically arranged on both sides of the servo motor 11 and have the same structure; a support 16 is fixedly connected to the end of the telescopic rod 15; an air jet head 17 is provided at the output end of the servo motor 11; an air guide pipe 18 is fixedly connected to the side wall of the air jet head 17; in use, when it is necessary to clean the residue in the mold body 1, the screw 13 is rotated to move along the side of the bracket 12. The wall moves, causing the fixing block 14 to fit tightly against the mold body 1, thus achieving a stable fixation of the servo motor 11. At the same time, the length of the telescopic rod 15 can be adjusted according to the mold size. The support 16 assists in supporting the servo motor 11, ensuring its working stability. After the servo motor 11 is started, it drives the jet head 17 to rotate, causing the jet head 17 to blow air over a wide range. Then, high-pressure gas is introduced through the air pipe 18 and sprayed out through the jet head 17 to blow away and clean the residue in the cavity and gaps of the mold body 1. During this process, the cooperation between the screw 13 and the fixing block 14 can achieve rapid fixation of the servo motor 11 on molds of different specifications, making it highly adaptable. The telescopic rod 15 and the support 16 enhance the overall stability of the equipment, preventing positional displacement caused by vibration during the cleaning process. High-pressure gas blowing can remove residue from the surface and gaps, thereby increasing the cleanliness of the mold body 1 and reducing residue residue.

[0026] Furthermore, such as Figures 1-5 As shown, a support rod 2 is fixedly connected to the output end of the servo motor 11; the support rod 2 and the jet head 17 are hinged; a top rod 21 is fixedly connected to the side wall of the jet head 17; an annular plate 22 is fixedly connected to the side wall of the servo motor 11; multiple protrusions 23 are evenly fixed to the side wall of the annular plate 22; the top rod 21 and the protrusions 23 are positioned correspondingly; in use, when the servo motor 11 drives the support rod 2 to rotate, the jet head 17 rotates synchronously with the support rod 2, and at the same time, the top rod 21 and the protrusions 23 on the annular plate 22 are aligned. 3. When the ejector pin 21 passes over the protrusion 23, the protrusion 23 pushes the ejector pin 21 to drive the jet head 17 to rotate around the hinge point, changing the jet angle. After the ejector pin 21 disengages from the protrusion 23, the jet head 17 returns to its original position, realizing the periodic change of the jet angle during rotation. In this process, through the cooperation between the protrusion 23 and the ejector pin 21, the jet head 17 can achieve multi-angle blowing without additional power, expanding the cleaning range and ensuring that residues in complex areas of the mold cavity can also be effectively removed, improving the thoroughness of cleaning.

[0027] Furthermore, such as Figures 1-5 As shown, a rotating rod 3 is rotatably connected to the side wall of the jet head 17; a fan blade 31 is fixedly connected to the middle of the rotating rod 3; a pair of fixing plates 32 are fixedly connected to the end of the rotating rod 3; the fixing plates 32 are symmetrically arranged on both sides of the rotating rod 3 and have the same structure; multiple cleaning brushes 33 are uniformly fixed to the side wall of the fixing plate 32; in use, the high-pressure airflow ejected from the jet head 17 drives the fan blade 31 to rotate, which in turn drives the rotating rod 3 and the fixing plate 32 to rotate. The cleaning brushes 33 on the fixing plate 32 rotate synchronously with the fixing plate 32 to clean the stubborn residue on the surface of the mold cavity. At the same time, the airflow blows away the cleaned residue in time. In this process, the airflow energy is used to drive the cleaning brushes 33 to rotate, realizing the coordinated cleaning of mechanical cleaning and airflow blowing, enhancing the cleaning effect of stubborn residue, without the need for an additional power source, and thus further improving the cleanliness of the mold body 1.

[0028] Furthermore, such as Figures 1-5As shown, a pair of sliding grooves 4 are symmetrically opened on the side wall of the fixed plate 32; the side wall of the sliding groove 4 is slidably connected to the same slider 41; an elastic rope 42 is fixedly connected between the slider 41 and the rotating rod 3; a pair of paddles 43 are symmetrically fixedly connected to the side wall of the slider 41; the paddles 43 are positioned corresponding to the cleaning brush 33; in use, when the rotating rod 3 rotates, the slider 41 slides outward along the sliding groove 4 under the action of centrifugal force, stretching the elastic rope 42, and the slider 41 drives the paddles 43 to slide across the surface of the cleaning brush 33, peeling off the fiber residue or plastic debris wrapped on the cleaning brush 33. After the rotating rod 3 stops rotating, the elastic rope 42 retracts and pulls the slider 41 back to its original position, and the paddles 43 return to their initial position. During this process, the paddles 43 are automatically driven by centrifugal force to clean the cleaning brush 33, avoiding the reduction of cleaning effect due to residue entanglement, extending the service life of the cleaning brush 33, eliminating the need for manual disassembly and cleaning, and ensuring the continuous working capability of the equipment.

[0029] Furthermore, such as Figures 1-5 As shown, the side wall of the fixing block 14 has a groove 5; a rubber pad 51 is fixedly connected to the side wall of the groove 5; during use, when the fixing block 14 contacts the mold body 1, the rubber pad 51 in the groove 5 undergoes elastic deformation, filling the tiny gap between the fixing block 14 and the mold surface, increasing the friction of the contact surface. At the same time, the rubber pad 51 can buffer the impact force when the screw 13 is tightened, preventing the fixing block 14 from scratching the mold surface. In this process, the rubber pad 51 improves the tightness of the fit between the fixing block 14 and the mold, reduces equipment slippage during cleaning, and the elastic deformation characteristics play a buffering and protective role, preventing the mold surface from being damaged due to rigid contact and protecting the mold precision.

[0030] Furthermore, such as Figures 1-5 As shown, a connecting rod 6 is fixedly connected to the side wall of the cleaning brush 33; the connecting rod 6 penetrates the wall of the cleaning brush 33 and is fixedly connected to it; in use, the connecting rod 6 penetrates the cleaning brush 33 and connects to the fixing plate 32, forming a rigid fixation between the bristles of the cleaning brush 33 and the fixing plate 32, thereby enhancing the structural strength of the cleaning brush 33 when cleaning stubborn residues, preventing the bristles from falling off or collapsing due to excessive force. In this process, the connecting rod 6 improves the overall firmness of the cleaning brush 33, extends its service life, ensures that the cleaning force is stably transmitted to the bristles, guarantees the cleaning effect on stubborn residues, and reduces the number of downtime maintenance caused by damage to the cleaning brush 33.

[0031] Working principle: During use, when it is necessary to clean the residue inside the mold body 1, the screw 13 is rotated to move along the side wall of the support 12, causing the fixing block 14 to fit tightly against the mold body 1, thus achieving a stable fixation of the servo motor 11. At the same time, the telescopic rod 15 can be adjusted in length according to the mold size, and the support 16 assists in supporting the servo motor 11 to ensure its working stability. After the servo motor 11 is started, it drives the jet head 17 to rotate, causing the jet head 17 to blow air over a wide range. Then, high-pressure gas is introduced into the air guide pipe 18 and sprayed out through the jet head 17. The mold body 1 cavity and gaps are cleaned by blowing away residue. During use, when the servo motor 11 drives the support rod 2 to rotate, the jet head 17 rotates synchronously with the support rod 2. At the same time, the ejector rod 21 contacts the protrusion 23 on the annular plate 22. When the ejector rod 21 passes the protrusion 23, the protrusion 23 pushes the ejector rod 21 to drive the jet head 17 to rotate around the hinge point, changing the jet angle. After the ejector rod 21 disengages from the protrusion 23, the jet head 17 returns to its original position, realizing the periodic change of the jet angle during rotation. During use, the high-pressure airflow ejected by the jet head 17 drives the fan blade 31 to rotate, driving... As the rotating rod 3 and the fixed plate 32 rotate, the cleaning brush 33 on the fixed plate 32 rotates synchronously with the fixed plate 32, cleaning stubborn residues on the surface of the mold cavity. At the same time, the airflow blows away the cleaned residues in time. During use, when the rotating rod 3 rotates, the slider 41 slides outward along the slide groove 4 under the action of centrifugal force, stretching the elastic rope 42. The slider 41 drives the paddle 43 to slide across the surface of the cleaning brush 33, peeling off the fiber residues or plastic debris wrapped on the cleaning brush 33. After the rotating rod 3 stops rotating, the elastic rope 42 retracts, pulling the slider 41 back to its original position, and the paddle 43 returns to its initial position. When in use, when the fixing block 14 contacts the mold body 1, the rubber pad 51 in the groove 5 undergoes elastic deformation, filling the tiny gap between the fixing block 14 and the mold surface, increasing the friction of the contact surface. At the same time, the rubber pad 51 can buffer the impact force when the screw 13 is tightened, preventing the fixing block 14 from scratching the mold surface. When in use, the connecting rod 6 passes through the cleaning brush 33 and connects to the fixing plate 32, rigidly fixing the bristles of the cleaning brush 33 to the fixing plate 32, enhancing the structural strength of the cleaning brush 33 when cleaning stubborn residues, and preventing the bristles from falling off or collapsing due to excessive force.
