Description

Technical Field

[0001] The present invention relates to the technical field of gear reducer cooling, and particularly to a cooling structure for a gear reducer used in an injection molding machine and its usage method. Background Art

[0002] An injection molding machine, also known as an injection molding press or an injection machine, is the main molding equipment for manufacturing various shaped plastic products by using thermoplastic or thermosetting plastics with plastic molding dies. It is divided into vertical, horizontal, and all-electric types. An injection molding machine can heat plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity. Injection molding is a cyclic process, and each cycle mainly includes: metering and feeding - melting and plasticizing - pressurizing and injecting - filling and cooling - opening the mold and taking out the part. After taking out the plastic part, the mold is closed again to carry out the next cycle.

[0003] Currently, the gear reducer used in an injection molding machine needs to work continuously following the injection molding machine. Long-term operation will cause high temperature inside the gear reducer. Currently, the gear reducer is generally cooled by the combination of a cooling fan and an air exhaust port. However, since the gear reducer is fixed in one position for a long time without moving, a large amount of dust will accumulate on the surfaces of the cooling fan and the air exhaust port, affecting the heat dissipation effect. The accumulation of dust on the surface of the cooling fan will affect the working air exhaust effect of the cooling fan. Summary of the Invention

[0011] A spring is fixedly connected to the surface of the stabilizing frame, and one end of the spring away from the stabilizing frame is fixedly connected to the pressing rod.

[0012] Further, the end of the rotating rod away from the heat dissipation motor penetrates through the sieve hole plate and extends to the outer end of the sieve hole plate, the fan blades are located inside the heat dissipation frame, the stabilizing frame is located at the end of the rotating rod away from the heat dissipation motor, the end of the pressing rod extends to the outer end of the stabilizing frame, and one end of the scraping plate away from the pressing rod contacts the surface of the sieve hole plate.

[0013] Further, the dust removal component includes a synchronous ring, the synchronous ring is fixedly connected to the end of the pressing rod, and an inclined panel is fixedly connected to the surface of the synchronous ring;

[0014] The synchronous ring is located inside the exhaust frame.

[0015] Further, the number of the inclined panels is eight, the eight inclined panels are arranged in four groups, and the number of each group is two. The surface of the triangular plate contacts the surface of the inclined panel and is located at the center of a single group of inclined panels.

[0016] Further, the collecting component includes a collecting frame, the collecting frame is fixedly connected to the inner wall of the rotating frame, sieve holes are formed on the surface of the collecting frame, a feeding hole is formed at one end of the collecting frame away from the sieve holes, a round hole rod is fixedly connected to the bottom of the collecting frame, and a storage frame is slidably connected to the inner wall of the round hole rod;

[0017] A push rod is fixedly connected to the end of the storage frame, a through hole is formed at one end of the collecting frame close to the round hole rod, a round hole plate is hinged to one end of the collecting frame away from the through hole, and one end of the connecting plate away from the rotating frame is fixedly connected to the surface of the stabilizing frame.

[0019] Further, a usage method of a cooling structure of a gear reducer for an injection molding machine includes the following steps:

[0020] S1: The end of the gear reducer is connected with a sieve plate through a heat dissipation frame. The gear reducer is cooled through the sieve plate. Start the heat dissipation component to work. When the heat dissipation component is operating, it will guide the heat inside the gear reducer to flow outwards.

[0021] S2: The airflow generated when the fan blades rotate will be discharged through the sieve plate into the inside of the exhaust frame for heat dissipation treatment, improving the cooling effect on the gear reducer. When the rotating rod rotates, it drives the extrusion rod to rotate through the stabilizing frame. When the extrusion rod rotates, it drives the scraper to clean the surface of the sieve plate.

[0023] S4: Dust will enter the inside of the collection frame through the feed hole and contact the surface of the round hole plate. The round hole plate will impact the inner wall of the through hole as the collection frame rotates, causing the dust to quickly fall into the inside of the storage frame for collection.

[0024] The present invention has the following beneficial effects:

[0025] In the present invention, the end of the gear reducer is connected with a sieve plate through a heat dissipation frame. The gear reducer is cooled through the sieve plate. Start the heat dissipation component to work. When the heat dissipation component is operating, it will guide the heat inside the gear reducer to flow outwards, thereby achieving the purpose of cooling the gear reducer. When the heat dissipation component rotates, it will contact the dust removal component, and the dust on the surface of the sieve plate is cleaned through the dust removal component. The collection component rotates synchronously with the heat dissipation component and collects dust while rotating, which can prevent dust from repeatedly accumulating on the surface of the sieve plate and affecting the heat dissipation effect.

[0026] In the present invention, start the heat dissipation motor to drive the rotating rod to rotate. When the rotating rod rotates, it drives the fan blades to rotate. The airflow generated when the fan blades rotate will be discharged through the sieve plate into the inside of the exhaust frame for heat dissipation treatment, improving the cooling effect on the gear reducer. When the rotating rod rotates, it drives the extrusion rod to rotate through the stabilizing frame. When the extrusion rod rotates, it drives the scraper to clean the surface of the sieve plate, preventing dust from blocking the sieve plate and causing the heat inside the gear reducer to not be discharged quickly. The extrusion rod uses the elasticity of the spring to squeeze the scraper, improving the cleaning effect of the scraper on the sieve plate.

[0027] When the extrusion rod of the present invention rotates, it drives the synchronous ring to rotate. When the synchronous ring rotates, it drives the inclined panel to contact the surface of the triangular plate. At this time, the inclined panel pushes the synchronous ring to move towards one end away from the sieve hole plate, and the scraper will separate from the surface of the sieve hole plate. When the inclined panel separates from the surface of the triangular plate, the scraper impacts the surface of the sieve hole plate through the elasticity of the spring, and the vibration generated by the impact can clean the scraper, avoiding dust adhering to the surface of the scraper and affecting the cleaning effect of the scraper.

[0028] When the stabilizing frame of the present invention rotates, it drives the rotating frame to rotate on the surface of the positioning ring through the connecting plate. When the rotating frame rotates, it pushes the collecting frame to collect dust. The dust will enter the inside of the collecting frame through the feed hole and contact the surface of the round hole plate. The round hole plate will impact the inner wall of the through hole as the collecting frame rotates, so that the dust will quickly fall into the inside of the storage frame through the through hole for collection, avoiding the dust cleaned from the surface of the sieve hole plate floating in the exhaust frame and repeatedly contacting the sieve hole plate to affect the cooling effect. When pushing the push rod to move, the push rod can push the storage frame to separate from the inner wall of the round hole rod, so as to process the dust in the storage frame.

[0029] Of course, it is not necessary for any product implementing the present invention to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

A rotating frame 33 is rotatably connected to the surface of the positioning ring 30. At the end of the gear reducer 1 of the present invention, a sieve plate 5 is connected through a heat dissipation frame 2. The gear reducer 1 is cooled by the sieve plate 5. The heat dissipation component 6 is started to work. When the heat dissipation component 6 operates, it guides the heat inside the gear reducer 1 to flow outwards, so as to achieve the purpose of cooling the gear reducer 1. When the heat dissipation component 6 rotates, it contacts the dust removal component 7. The dust on the surface of the sieve plate 5 is cleaned by the dust removal component 7. The collecting component 8 rotates synchronously with the heat dissipation component 6 and collects dust while rotating, which can avoid the repeated accumulation of dust on the surface of the sieve plate 5 and affect the heat dissipation effect. A connecting plate 32 is fixedly connected to the inner wall of the rotating frame 33.

[0047] The heat dissipation component 6 includes a stabilizing frame 15. The stabilizing frame 15 is fixedly connected to the end of a rotating rod 17. A pressing rod 16 is slidably connected to the inner wall of the stabilizing frame 15. A scraping plate 13 is fixedly connected to the end of the pressing rod 16.

[0048] A spring 14 is fixedly connected to the surface of the stabilizing frame 15. In the present invention, the heat dissipation motor 12 is started to drive the rotating rod 17 to rotate. When the rotating rod 17 rotates, it drives the fan blade 18 to rotate. The airflow generated when the fan blade 18 rotates is discharged through the sieve plate 5 to the inside of the exhaust frame 3 for heat dissipation treatment, improving the cooling effect on the gear reducer 1. When the rotating rod 17 rotates, it drives the pressing rod 16 to rotate through the stabilizing frame 15. When the pressing rod 16 rotates, it drives the scraping plate 13 to clean the surface of the sieve plate 5, avoiding the blockage of the sieve plate 5 by dust and preventing the heat inside the gear reducer 1 from being quickly discharged. The pressing rod 16 uses the elasticity of the spring 14 to press the scraping plate 13, improving the cleaning effect of the scraping plate 13 on the sieve plate 5. The end of the spring 14 away from the stabilizing frame 15 is fixedly connected to the pressing rod 16.

[0049] The end of the rotating rod 17 away from the heat dissipation motor 12 penetrates through the sieve plate 5 and extends to the outside of the sieve plate 5. The fan blade 18 is located inside the heat dissipation frame 2. The stabilizing frame 15 is located at the end of the rotating rod 17 away from the heat dissipation motor 12.

[0052] The number of the inclined plates 23 is set to eight. The eight inclined plates 23 are set in four groups, and the number of each group is set to two. When the extrusion rod 16 of the present invention rotates, it drives the synchronous ring 22 to rotate. When the synchronous ring 22 rotates, it drives the inclined plate 23 to contact the surface of the triangular plate 24. At this time, the inclined plate 23 pushes the synchronous ring 22 to move towards the end away from the screen plate 5, and the scraping plate 13 will separate from the surface of the screen plate 5. When the inclined plate 23 separates from the surface of the triangular plate 24, the scraping plate 13 impacts the surface of the screen plate 5 through the elasticity of the spring 14. The vibration generated by the impact can clean the scraping plate 13, avoiding dust adhering to the surface of the scraping plate 13 and affecting the cleaning effect of the scraping plate 13. The surface of the triangular plate 24 contacts the surface of the inclined plate 23 and is located at the center of a single group of inclined plates 23.

[0053] The collecting component 8 includes a collecting frame 36. The collecting frame 36 is fixedly connected to the inner wall of the rotating frame 33. The surface of the collecting frame 36 is provided with screen holes 34. One end of the collecting frame 36 away from the screen holes 34 is provided with a feed hole 37.

When the stabilizing frame 15 of the present invention rotates, it drives the rotating frame 33 to rotate on the surface of the positioning ring 30 through the connecting plate 32. When the rotating frame 33 rotates, it pushes the collecting frame 36 to collect dust. The dust will enter the interior of the collecting frame 36 through the feed hole 37 and contact the surface of the round hole plate 39. The round hole plate 39 will impact the inner wall of the through hole 40 as the collecting frame 36 rotates, so that the dust will quickly fall into the interior of the storage frame 35 through the through hole 40 for collection, avoiding the dust cleaned from the surface of the screen plate 5 floating in the exhaust frame 3 and repeatedly contacting the screen plate 5 to affect the cooling effect. When pushing the push rod 38 to move, the push rod 38 can push the storage frame 35 to separate from the inner wall of the round hole rod 31, so as to process the dust in the storage frame 35.

[0056] A method for using a cooling structure of a gear reducer for an injection molding machine includes the following steps:

[0057] S1: One end of the gear reducer 1 is connected to a sieve plate 5 through a heat dissipation frame 2. The gear reducer 1 is cooled through the sieve plate 5. The heat dissipation component 6 is started to work. When the heat dissipation component 6 is operating, it will guide the heat inside the gear reducer 1 to flow outwards;

[0058] S2: The airflow generated when the fan blade 18 rotates will be discharged through the sieve plate 5 to the inside of the exhaust frame 3 for heat dissipation treatment, improving the cooling effect on the gear reducer 1. When the rotating rod 17 rotates, it drives the extrusion rod 16 to rotate through the stabilizer 15. When the extrusion rod 16 rotates, it drives the scraper 13 to clean the surface of the sieve plate 5;

[0059] S3: The scraper 13 will separate from the surface of the sieve plate 5. When the inclined surface plate 23 separates from the surface of the triangular plate 24, the scraper 13 impacts the surface of the sieve plate 5 through the elasticity of the spring 14. The vibration generated by the impact can clean the scraper 13;

[0060] S4: Dust will enter the inside of the collection frame 36 through the feed hole 37 and contact the surface of the round hole plate 39. The round hole plate 39 will impact the inner wall of the through hole 40 as the collection frame 36 rotates, causing the dust to quickly fall into the inside of the storage frame 35 for collection.

[0061] During use, the end of the gear reducer 1 is connected to a sieve plate 5 through a heat dissipation rack 2. The gear reducer 1 is cooled through the sieve plate 5. The heat dissipation component 6 is started to work. When the heat dissipation component 6 is operating, it will guide the heat inside the gear reducer 1 to flow outwards, thereby achieving the purpose of cooling the gear reducer 1. When the heat dissipation component 6 rotates, it will contact the dust removal component 7, and the dust on the surface of the sieve plate 5 is cleaned by the dust removal component 7. The collection component 8 rotates synchronously with the heat dissipation component 6 and collects the dust while rotating, which can prevent the dust from accumulating repeatedly on the surface of the sieve plate 5 and affecting the heat dissipation effect. The heat dissipation motor 12 is started to drive the rotating rod 17 to rotate. When the rotating rod 17 rotates, it drives the fan blade 18 to rotate. The airflow generated when the fan blade 18 rotates is discharged through the sieve plate 5 into the exhaust rack 3 for heat dissipation treatment, improving the cooling effect on the gear reducer 1. When the rotating rod 17 rotates, it drives the extrusion rod 16 to rotate through the stabilizing frame 15. When the extrusion rod 16 rotates, it drives the scraping plate 13 to clean the surface of the sieve plate 5, preventing the dust from blocking the sieve plate 5 and causing the heat inside the gear reducer 1 to not be discharged quickly. The extrusion rod 16 uses the elasticity of the spring 14 to squeeze the scraping plate 13, improving the cleaning effect of the scraping plate 13 on the sieve plate 5. When the extrusion rod 16 rotates, it will drive the synchronous ring 22 to rotate. When the synchronous ring 22 rotates, it drives the inclined panel 23 to contact the surface of the triangular plate 24. At this time, the inclined panel 23 pushes the synchronous ring 22 to move away from the sieve plate 5, and the scraping plate 13 will separate from the surface of the sieve plate 5. When the inclined panel 23 separates from the surface of the triangular plate 24, the scraping plate 13 impacts the surface of the sieve plate 5 through the elasticity of the spring 14. The vibration generated by the impact can clean the scraping plate 13, preventing the dust from adhering to the surface of the scraping plate 13 and affecting the cleaning effect of the scraping plate 13. When the stabilizing frame 15 rotates, it drives the rotating frame 33 to rotate on the surface of the positioning ring 30 through the connecting plate 32. When the rotating frame 33 rotates, it pushes the collection frame 36 to collect the dust. The dust will enter the inside of the collection frame 36 through the feed hole 37 and contact the surface of the round hole plate 39. The round hole plate 39 will impact the inner wall of the through hole 40 as the collection frame 36 rotates, causing the dust to quickly fall into the storage rack 35 through the through hole 40 for collection, preventing the dust cleaned from the surface of the sieve plate 5 from floating in the exhaust rack 3 and repeatedly contacting the sieve plate 5 and affecting the cooling effect. When the push rod 38 is pushed to move, the push rod 38 can push the storage rack 35 to separate from the inner wall of the round hole rod 31, so as to process the dust in the storage rack 35.

The cooling structure of a gear reducer for an injection molding machine according to claim 2, characterized in that: One end of the push rod (38) away from the storage rack (35) passes through the round hole rod (31) and extends to the outer end of the round hole rod (31); the collection rack (36) is connected to the storage rack (35) via the through hole (40); and one end of the round hole plate (39) away from the collection rack (36) extends to the inside of the through hole (40).

4. The method for using the cooling structure of a gear reducer used in an injection molding machine according to claim 3, characterized in that: The following steps are involved: S1: The end of the gear reducer (1) is connected to a sieve plate (5) via a heat dissipation frame (2), the gear reducer (1) is cooled by the sieve plate (5), and the heat dissipation component (6) is started to work. When the heat dissipation component (6) is in operation, it guides the heat inside the gear reducer (1) to flow outwards; S2: When the fan blades (18) rotate, the airflow generated is discharged from the inside of the exhaust frame (3) through the sieve plate (5) for heat dissipation, thereby improving the cooling effect on the gear reducer (1). When the rotating rod (17) rotates, it drives the extrusion rod (16) to rotate through the stabilizing frame (15). When the extrusion rod (16) rotates, it drives the scraper (13) to clean the surface of the sieve plate (5); S3: The scraper (13) is separated from the surface of the sieve plate (5). When the inclined plate (23) is separated from the surface of the triangular plate (24), the scraper (13) impacts the surface of the sieve plate (5) through the elasticity of the spring (14). The vibration generated by the impact can clean the scraper (13); S4: The dust enters the interior of the collecting rack (36) through the feed hole (37) and contacts the surface of the circular hole plate (39). The circular hole plate (39) hits the inner wall of the through hole (40) as the collecting rack (36) rotates, so that the dust quickly falls through the through hole (40) to the interior of the storage rack (35) for collection.
