Description

Technical Field

[0001] The invention relates to the technical field of gear reducer cooling, in particular to a gear reducer cooling structure used in an injection molding machine and a use method thereof. Background Art

[0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. Injection molding is a cyclic process. Each cycle mainly includes: quantitative feeding - melting and plasticization - pressure injection - mold filling and cooling - mold opening and taking out the plastic parts. After taking out the plastic parts, the mold is closed again for the next cycle.

[0003] At present, the gear reducer used in the injection molding machine needs to follow the injection molding machine to perform continuous operation. Long-term operation will cause high temperature inside the gear reducer. The current gear reducer is generally cooled by a combination of a cooling fan and an exhaust port. However, the gear reducer is fixed in one position for a long time and will not move, which will cause a large amount of dust to accumulate on the surface of the cooling fan and the exhaust port, affecting the heat dissipation effect. The dust accumulated on the surface of the cooling fan will affect the working 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 extrusion rod.

[0012] Furthermore, one end of the rotating rod away from the heat dissipation motor passes through the sieve plate and extends to the outer end of the sieve 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 extrusion rod extends to the outer end of the stabilizing frame, and one end of the scraper away from the extrusion rod contacts the surface of the sieve plate.

[0013] Further, the dust removal component comprises a synchronization ring, the synchronization ring is fixedly connected to the end of the extrusion rod, and a sloped plate is fixedly connected to the surface of the synchronization ring;

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

[0015] Furthermore, the number of the inclined panels is eight, the eight inclined panels are arranged into four groups, and the number of each group is two, and 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 comprises a collecting rack, the collecting rack is fixedly connected to the inner wall of the rotating rack, a sieve hole is provided on the surface of the collecting rack, a feeding hole is provided at one end of the collecting rack away from the sieve hole, a round hole rod is fixedly connected to the bottom of the collecting rack, and a storage rack 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 rack, a through hole is opened at one end of the collection rack close to the round hole rod, a round hole plate is hinged at one end of the collection rack away from the through hole, and the end of the connecting plate away from the rotating frame is fixedly connected to the surface of the stabilizing frame.

[0019] Furthermore, a method for using a gear reducer cooling structure for an injection molding machine comprises the following steps:

The heat dissipation component is started to work, and the heat dissipation component guides the heat inside the gear reducer to flow outward during operation;

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

[0022] S3: The scraper will separate from the surface of the sieve plate.

[0023] S4: The dust will enter the interior of the collection rack through the feed hole and contact the surface of the circular hole plate. The circular hole plate will hit the inner wall of the through hole as the collection rack rotates, so that the dust will quickly fall through the through hole to the interior of the storage rack for collection.

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

[0025] The end of the gear reducer of the present invention is connected to a sieve plate through a heat dissipation frame, and the gear reducer is heat-dissipated by the sieve plate. The heat dissipation component is started to work, and the heat dissipation component guides the heat inside the gear reducer to flow outward during operation, thereby achieving the purpose of cooling the gear reducer. The heat dissipation component will contact the dust removal component when rotating, and the dust on the surface of the sieve plate will be cleaned by the dust removal component. The collecting 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] The present invention starts the heat dissipation motor to drive the rotating rod to rotate, and the rotating rod drives the fan blades to rotate when rotating. The airflow generated by the fan blades when rotating will be discharged from the interior of the exhaust frame through the sieve plate for heat dissipation treatment, thereby improving the cooling effect on the gear reducer. The rotating rod drives the extrusion rod to rotate through the stabilizing frame when rotating, and the extrusion rod drives the scraper to clean the surface of the sieve plate when rotating, thereby preventing dust from blocking the sieve plate and causing the heat inside the gear reducer to be unable to be quickly discharged. The extrusion rod uses the elasticity of the spring to extrude the scraper, thereby improving the cleaning effect of the scraper on the sieve plate.

[0027] When the extrusion rod of the present invention rotates, it will drive the synchronous ring to rotate. When the synchronous ring rotates, it will drive the inclined plate to contact the surface of the triangular plate. At this time, the inclined plate pushes the synchronous ring to move toward the end away from the sieve plate, and the scraper will be separated from the surface of the sieve plate. When the inclined plate is separated from the surface of the triangular plate, the scraper will impact the surface of the sieve plate through the elasticity of the spring. The vibration generated by the impact can clean the scraper, thereby preventing dust from 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, the connecting plate drives the rotating frame to rotate on the surface of the positioning ring. When the rotating frame rotates, the collecting frame is pushed to collect the dust. The dust enters the interior of the collecting frame through the feeding hole and contacts the surface of the circular hole plate. The circular hole plate hits the inner wall of the through hole as the collecting frame rotates, so that the dust quickly falls through the through hole to the interior of the storage frame for collection, thereby preventing the dust cleaned on the surface of the sieve plate from floating in the interior of the exhaust frame and repeatedly contacting the sieve plate to affect the cooling effect. When the push rod is pushed to move, the push rod can push the storage frame to separate from the inner wall of the circular hole rod, so as to process the dust in the storage frame.

[0029] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the inclined panel 23 pushes the synchronous ring 22 to move toward the end away from the sieve plate 5, and the scraper 13 will be separated from the surface of the sieve plate 5. When the inclined panel 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 extrusion rod 16 uses the elasticity of the spring 14 to squeeze the scraper 13, thereby improving the cleaning effect of the scraper 13 on the sieve plate 5, squeezing When the pressure rod 16 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 to the end away from the sieve plate 5, and 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 cooling structure of a gear reducer for an injection molding machine according to claim 5, characterized in that: The collecting component (8) comprises a collecting frame (36), the collecting frame (36) is fixedly connected to the inner wall of the rotating frame (33), a sieve hole (34) is provided on the surface of the collecting frame (36), a feeding hole (37) is provided at one end of the collecting frame (36) away from the sieve hole (34), a round hole rod (31) is fixedly connected to the bottom of the collecting frame (36), and a storage frame (35) is slidably connected to the inner wall of the round hole rod (31); The end of the storage rack (35) is fixedly connected to a push rod (38); an end of the collection rack (36) close to the round hole rod (31) is provided with a through hole (40); an end of the collection rack (36) away from the through hole (40) is hingedly connected to a round hole plate (39); and an end of the connecting plate (32) away from the rotating rack (33) is fixedly connected to the surface of the stabilizing rack (15).

7. The cooling structure of a gear reducer for an injection molding machine according to claim 6, 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) through 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).

8. The method for using the cooling structure of a gear reducer used in an injection molding machine according to claim 7, characterized in that: The following steps are involved: S1: The end of the gear reducer (1) is connected to a sieve plate (5) through a heat dissipation frame (2), the gear reducer (1) is heat-dissipated through 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: The airflow generated by the fan blades (18) when rotating 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) will separate from the surface of the sieve plate (5). When the inclined 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); S4: The dust will enter the interior of the collecting rack (36) through the feed hole (37) and come into contact with the surface of the circular hole plate (39). The circular hole plate (39) will hit the inner wall of the through hole (40) as the collecting rack (36) rotates, so that the dust will quickly fall through the through hole (40) to the interior of the storage rack (35) for collection.
