Description

Technical Field

[0001] This utility model relates to the field of motor heat dissipation technology, and in particular to a heat dissipation device for a servo motor of an all-electric injection molding machine. Background Technology

[0002] Servo motors in injection molding machines operate under conditions of high-frequency start-stop, high load, and enclosed environment. Heat dissipation directly affects their performance, lifespan, and system stability. Servo motor rotors typically use permanent magnets (such as neodymium iron boron), and high temperatures can cause magnetic decay or even demagnetization, thereby reducing torque output capability. The insulation layer of the motor windings may deteriorate under continuous high temperatures, leading to short circuits or leakage faults.

[0003] A search revealed that utility model patent CN218124501U discloses a cooling motor, comprising: a main body, fan blades, and an annular protective cover. One end of the main body has an output shaft; the fan blades are mounted on the output shaft, with the air outlet side of the fan blades facing the main body; the annular protective cover is movably connected to the output shaft, and the fan blades are located inside the annular protective cover. By setting an annular protective cover movably connected to the output shaft, the fan blades are positioned inside the annular protective cover. The fan blades are connected to the output shaft, and the rotation of the output shaft drives the fan blades to rotate. The annular protective cover, movably connected to the output shaft, remains stationary relative to the fan blades, reducing the power loss of the output shaft. The air outlet side of the fan blades blows cooling airflow towards the main body to dissipate heat. The annular protective cover not only protects the fan blades but also reduces the influence of external airflow on the cooling airflow, allowing the cooling airflow to be more concentrated and directed towards the main body of the cooling motor, thus improving the heat dissipation effect.

[0004] In the aforementioned structure, since the annular mounting base is a single unit, once the motor output shaft is fixed to the equipment, if the operator needs to remove the fan blades, the fixing between the motor and the equipment must be removed first, resulting in a long downtime and reduced production efficiency. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a heat dissipation device for the servo motor of an all-electric injection molding machine.

[0014] Beneficial effects:

[0015] 1. This utility model achieves the goal of setting corresponding semi-circular parts at the corresponding positions of multiple fixing rings, so that when the fixing rings need to be installed or removed, the output end of the motor body can be removed without disassembling the equipment by rotating the semi-circular parts to a predetermined position and pulling them to both sides, thereby removing the fixing rings and turbine blades. After maintenance, the fixing rings can be installed and fixed by simply pressing the multiple corresponding fixing rings lightly under the action of the retaining springs, thereby reducing downtime and improving work and maintenance efficiency.

[0016] 2. This utility model enables workers to easily control the rotation of the semicircular part when it is necessary to disassemble the fixing rings by means of a connecting rod, control block and limiting arc groove. The semicircular part is rotated at a certain angle to disengage multiple fixing rings, thereby making it easier for workers to control the semicircular part and further reducing downtime.

[0017] 3. This utility model achieves the restriction of the blocking groove and the blocking block, so that the operator can feel obvious resistance when rotating the semi-circular part to reach a predetermined angle, thus providing feedback to the operator. At the same time, it prevents the fixed rings from being unable to disengage or the snap ring from being damaged due to excessive rotation by the operator, thereby improving the user experience and further improving work efficiency.

[0034] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0035] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0037] Reference Figures 1-6 A heat dissipation device for a servo motor of an all-electric injection molding machine includes multiple fixing rings 102. The fixing rings 102 are located on the circumference of an output end 101. A motor body 1 is located at one end of the output end 101, and a support assembly is fixed to the bottom of the motor body 1. Multiple turbine blades 103 are fixed in a circular array on the circumference of the fixing rings 102. A protective ring is provided on the outer surface of each turbine blade 103. A semi-circular groove is formed at one end of the fixing rings 102. Short columns are fixed to both sides of the inner wall of the semi-circular groove. A semi-circular component 2 is provided on the inner wall of the semi-circular groove. Motion arc grooves 201 are formed on both sides of the semi-circular component 2. The inner wall of the motion arc grooves 201 is slidably connected to the surface of the short columns. One end of the semi-circular component 2 is provided with… The retaining ring 202, with corresponding semicircular parts 2 set at the corresponding positions of multiple retaining rings 102, allows the retaining rings 102 to be installed or removed when needed. This is achieved by rotating the semicircular parts 2 to a predetermined position and pulling them to both sides without disassembling the output end 101 of the motor body 1. This removes the fixing between the multiple retaining rings 102 and the turbine blade 103. After maintenance, the multiple corresponding retaining rings 102 can be installed and fixed by simply pressing them gently, under the action of the retaining ring 202, which greatly reduces downtime.

[0038] One end of the semicircular part 2 is fixed with a hook ring 302. The bottom of the inner wall of the semicircular groove is provided with an installation groove 3. The inner wall of the installation groove 3 is connected to the inner wall of the semicircular groove. Multiple fixing posts 301 are fixed on the inner wall of the installation groove 3. A retaining spring 202 is provided on the circumference of one fixing post 301. One end of the retaining spring 202 is attached to the circumference of another fixing post 301, and the other end of the retaining spring 202 is anchored to the surface of the hook ring 302. The retaining spring 202 causes the multiple semicircular parts 2 to contact each other and squeeze and rotate simultaneously when the fixing ring 102 is installed. After the fixing ring 102 is installed, the semicircular parts 2 that have rotated a certain angle will be pulled by the elastic potential energy released by the retaining spring 202 and gradually rotate back to their original position, so that a part of the semicircular parts 2 enters the semicircular groove of another fixing ring 102, thereby forming a better fixing effect without the need for the operator to rotate them manually.

[0039] Multiple anti-slip grooves 4 are linearly arrayed on the surface of the semi-circular part 2. The anti-slip grooves 4 increase the friction between the multiple semi-circular parts 2, prevent the contact surfaces of the semi-circular parts 2 from slipping, maintain the fit between the two, and prevent damage caused by the left and right displacement of the semi-circular parts 2 when the motor body 1 is working.

[0040] The fixed ring 102 has a limiting arc groove 501 on its side. A connecting rod 5 is fixed on one side of the semi-circular part 2. The circumference of the connecting rod 5 is slidably connected to the inner wall of the limiting arc groove 501. A control block 503 is fixed at one end of the connecting rod 5. The connecting rod 5, the control block 503 and the limiting arc groove 501 allow the operator to easily control the rotation of the semi-circular part 2 when it is necessary to disassemble the fixed ring 102. This allows the semi-circular part 2 to rotate at a certain angle, thereby detaching multiple fixed rings 102. This makes it easier for the operator to control the semi-circular part 2 and further reduces downtime.

[0041] One side of the control block 503 is designed with a pressing arc surface 6. The pressing arc surface 6 prevents hand pain when the operator presses and pinches the control block 503 to rotate, thus improving the user experience.

[0042] A blocking groove 7 is provided on one side of the semicircular part 2. A blocking block 701 is fixed at the top of the inner wall of the semicircular groove. By restricting the semicircular part 2 with the blocking groove 7 and the blocking block 701, the operator can feel obvious resistance when rotating the semicircular part 2 to reach a predetermined angle, thereby giving the operator feedback. At the same time, it prevents the fixed ring 102 from being unable to disengage or the snap ring 202 from being damaged due to excessive rotation by the operator.

[0043] The inner wall of the blocking block 701 is fixed with a fixing triangular piece 9. One side of the fixing triangular piece 9 is fixed to the inner wall of the semi-circular groove. The fixing triangular piece 9 improves the fixing effect between the blocking block 701 and the inner wall of the semi-circular groove, preventing it from tilting or breaking.

[0044] One end of the fixing ring 102 is fixed with a protrusion 8. One end of the protrusion 8 is provided with multiple auxiliary inclined surfaces 802. An auxiliary arc groove 502 is opened on one side of the protrusion 8. The fixing ring 102 is provided with a positioning groove 801 above the protrusion 8. The cooperation between the protrusion 8 and the positioning groove 801 prevents the operator from visually judging whether the two ends of the fixing ring 102 are aligned when there are many components on the inner wall of the equipment and the structure is complex. The cooperation between the two makes it easier for the operator to judge and position by feel. At the same time, the auxiliary inclined surface 802 provides guidance when it contacts the protrusion 8, which makes it easier for the operator to judge the installation position and improves the installation efficiency. Specific Implementation Example 2:

[0046] Reference Figures 1-6Workers used the structure disclosed in this utility model on an MA6500 injection molding machine at a factory. The output end 101 of the servo motor body 1 (Yaskawa SGM7G-75A) was connected to a ball screw. When the motor winding temperature reached 85℃ (threshold 80℃) and the cooling turbine needed cleaning, the operator pressed the pressing arc surface 6 (radius of curvature R8) of the control block 503, driving the semi-circular part 2 to rotate 30° via the connecting rod 5. The moving arc groove 201 slid along the short column of the fixed ring 102 until the blocking groove 7 abutted against the blocking block 701 (tactile feedback force 18N). At this time, the retaining spring 202 (SUS304-WPB, wire diameter 1.0mm) was stretched and stored energy, and the mechanical interlock between adjacent fixed rings 102 was released. After the two halves of the fixed ring 102 were radially separated, the circumferential array of aluminum alloy turbine blades 103 (diameter 180mm) was fully exposed. The cleaning operation took 3 minutes.

[0047] During reinstallation, the protrusion 8 (auxiliary inclined surface 802 at a 45° angle) is aligned with the positioning groove 801 and gently pushed. The snap ring 202 automatically retracts upon contact with the semicircular part 2, pulling the hook 302 to rotate the semicircular part 2 in the opposite direction and reset it. The fixed triangular part 9 strengthens the shear strength of the blocking block 701 (measured shear force > 1200N), ensuring that the semicircular part 2 is accurately embedded in the adjacent semicircular groove. After the motor restarts, a test showed that at 2500rpm, the turbine blade 103 generates 12m... 3 / min airflow, motor temperature stabilized at 76℃. Compared to traditional disassembly and assembly methods (requiring removal of output end 101 connector, averaging 105 minutes), the maintenance time of this device is reduced to 8 minutes, and annual downtime due to failure is reduced by 37 hours. After six months of continuous operation, the wear on the mating surface between the moving arc groove 201 and the short column was only 0.02mm.

[0048] The working principle of this utility model is as follows: When the output end 101 of the servo motor rotates, it drives the fixed ring 102 and the turbine blades 103 of the circumferential array to rotate synchronously, generating directional airflow to force heat dissipation on the motor body 1; when the turbine blades 103 need maintenance, the operator presses the pressing arc surface 6 of the control block 503, which drives the semi-circular part 2 to rotate along the short column in the semi-circular groove of the fixed ring 102 through the connecting rod 5. The moving arc groove 201 slides with the short column. When the rotation reaches the stop groove 7 and abuts against the stop block 701, the operator receives tactile feedback to stop the rotation; at this time, the snap ring 202 is stretched, with one end anchored to the hook ring 302 and the other end to the fixed column 3. The contact of 01 creates a constraint, preventing the snap ring 202 from rotating, thereby accumulating elastic potential energy. The interlock between multiple fixed rings 102 is released, and the turbine blade 103 can be radially separated and disassembled without disassembling the connection between the motor output end 101 and the equipment. During reinstallation, the protrusion 8 of the fixed ring 102 is aligned with the positioning groove 801 of the adjacent fixed ring 102 and the auxiliary inclined surface 802 is used for guidance and alignment. The fixed ring 102 is lightly pressed to make the semicircular part 2 contact. The snap ring 202 automatically retracts and pulls the hook ring 302, forcing the semicircular part 2 to rotate in the opposite direction and reset to embed into the adjacent semicircular groove. At the same time, the connecting rod 5 slides back to the initial position along the limiting arc groove 501, completing the mechanical interlock.

[0049] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
