Description

Technical Field

[0001] This utility model relates to the field of hydraulic pump stations, and in particular to a hydraulic pump station for injection molded parts with heat dissipation components. Background Technology

[0002] The hydraulic pump station for injection molding parts is a core component that provides hydraulic power to the injection molding machine. It converts electrical energy into hydraulic energy through a hydraulic pump, driving various hydraulic systems of the injection molding machine, such as injection, mold closing, and mold clamping. It mainly includes an oil tank, electric motor, hydraulic pump, and control valves.

[0003] Existing technologies, such as the utility model patent with publication number CN212509070U, disclose a high-efficiency heat-dissipating hydraulic pump station, including a hydraulic oil tank. An oil level and temperature gauge is installed on one side of the front outer surface of the hydraulic oil tank. A hydraulic gear pump is installed on one side of the top of the hydraulic oil tank. A soundproof cover is provided on the outer wall of the hydraulic gear pump and controller. An instrument panel is fixedly connected to the rear end of the top side of the hydraulic oil tank. A mounting base is fixedly connected to one side of the front end of the top of the hydraulic oil tank. Connection interfaces are provided on both sides of the front end of the mounting base. A main cooling fan is installed at the end of the soundproof cover near the instrument panel, and a soundproofing plate is fixedly connected to the center of the end of the soundproof cover away from the main cooling fan. In this utility model, the high-efficiency heat-dissipating hydraulic pump station not only has a high-efficiency heat dissipation mechanism but also a sound insulation mechanism. It can achieve rapid heat dissipation while also providing effective sound insulation, thereby greatly improving its working efficiency and solving the problem of excessive heat generation during operation of the hydraulic pump station.

[0004] During the injection molding process using a hydraulic pump station, it was found that the electric motor in the hydraulic pump station generates a lot of heat when it is working. If it is used for a long time without timely heat dissipation, the efficiency of the motor will decrease, which will cause the motor to consume more electrical energy to maintain operation, resulting in reduced work efficiency. Therefore, a heat dissipation device is needed to dissipate heat from the motor. However, some existing heat dissipation devices can only blow heat to a specific location, resulting in uneven heat dissipation and poor heat dissipation effect, which affects work efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, the electric motor of a hydraulic pump station generates a lot of heat when it is working. If it is not cooled in time after prolonged use, the efficiency of the electric motor will decrease, which will cause the electric motor to consume more electrical energy to maintain operation, resulting in reduced work efficiency. Therefore, a heat dissipation device is needed to cool the electric motor. However, some heat dissipation devices in the prior art can only blow on a specific location, resulting in uneven heat dissipation and poor heat dissipation effect, which affects work efficiency.

[0006] To solve the above technical problems, this utility model provides a hydraulic pump station for injection molded parts with a heat dissipation component, comprising: an oil tank, several oil delivery pipes, an electric motor mounted on one side of the upper surface of the oil tank, a hydraulic pump body mounted on the output end of the electric motor, a control valve mounted on one side of the upper surface of the oil tank, one side of the hydraulic pump body being fixedly connected to the oil tank via an oil delivery pipe, and the other side of the hydraulic pump body being fixedly connected to the control valve via an oil delivery pipe. One side of the control valve is fixedly connected to the oil tank via an oil delivery pipe. A control cabinet is mounted on one side of the upper surface of the oil tank. A heat dissipation device is provided on one side of the oil tank corresponding to the position of the electric motor. The heat dissipation device includes a fan, one end of which is fixedly connected to the oil tank, and a fan duct fixedly connected to one side of the fan. The fan duct is constricted in shape, and a ventilation pipe is fixedly connected to one side of the fan duct. A conveying pipe is rotatably connected, and support rings are rotatably connected to both sides of the arc surface of the conveying pipe. A support rod is fixedly connected to one side of the arc surface of the support ring. The support rod has an "L"-shaped cross-section. The short arm ends of the two support rods are fixedly connected to the same support plate. The support plate has a "U"-shaped cross-section. One end of the support plate is fixedly connected to the oil tank. A drive motor is fixedly connected to the upper surface of the support plate. A rotating rod is fixedly connected to the output end of the drive motor. A turntable is fixedly connected to one end of the rotating rod. An adjusting rod slides through the inner wall of one side of the turntable. A sliding sleeve is fixedly connected to one end of the adjusting rod. A connecting rod is movably connected to the inner wall of the sliding sleeve. Connecting blocks are fixedly connected to both ends of the arc surface of the connecting rod. The inner walls of the two connecting blocks are fixedly connected to the same conveying pipe. Several extension pipes are fixedly connected to one side of the conveying pipe.

[0007] The effects achieved by the above components are as follows: the heat dissipation device generates cooling airflow through the fan via the control cabinet. The airflow is accelerated through the constricted air duct and then enters the ventilation pipe and delivery pipe. The drive motor then rotates the rotating rod, which in turn rotates the turntable. The adjusting rod is moved along the inner wall of the turntable while being carried by the turntable. The sliding sleeve is oscillating while sliding on the connecting rod. The delivery pipe rotates back and forth within the support ring through the connecting block. In this way, several extension pipes oscillate back and forth to blow air evenly onto the motor, achieving dynamic heat dissipation, expanding the heat dissipation area, effectively preventing the motor from overheating, and improving the operational stability of the hydraulic pump station.

[0008] Preferably, the arc surface of the connecting rod is fixedly connected with an anti-jamming sleeve, which is a Teflon sleeve.

[0009] The effects achieved by the above components are as follows: the anti-jamming sleeve utilizes the low friction properties of Teflon material to reduce the frictional resistance of the connecting rod during movement, prevent jamming between the connecting rod and the sliding sleeve, ensure smooth swing of the delivery pipe, and improve the reliability and service life of the heat dissipation device.

[0010] Preferably, a plurality of heat sinks are fixedly connected to one side of the inner wall of the support plate, and one side of the plurality of heat sinks is fixedly connected to the same motor.

[0011] The effect achieved by the above components is to quickly conduct the heat generated by the motor to the support plate and dissipate it into the surrounding air through the metal heat sink, thereby enhancing the heat dissipation effect and helping to reduce the motor temperature.

[0012] Preferably, a sound insulation board, which is a rubber board, is fixedly connected to one side of the inner wall of the support plate.

[0013] The effects achieved by the above components are as follows: the sound insulation panel utilizes the elasticity and sound absorption properties of rubber material to absorb the vibration and noise generated by the motor during operation, reduce noise pollution in the working environment, and improve operational comfort and the environmental friendliness of the equipment.

[0014] Preferably, a fixing rod is fixedly connected to the arc surface of the ventilation pipe, and one end of the fixing rod is fixedly connected to the oil tank.

[0015] The above components achieve the following effects: the fixing rod securely fixes the ventilation pipe to the oil tank, preventing the ventilation pipe from shifting or loosening due to airflow impact or equipment vibration, ensuring the stability of the airflow channel and guaranteeing continuous and efficient delivery of heat dissipation airflow.

[0016] Preferably, one end of the extension tube is fixedly connected to a funnel-shaped air duct, which is flared.

[0017] The effects achieved by the above components are as follows: the flared design of the funnel duct increases the airflow outlet area, allowing the cooling airflow to spread more evenly to the surface of the motor, avoiding local overheating, improving the heat dissipation coverage and efficiency, while reducing airflow resistance and optimizing airflow distribution.

[0018] Compared with related technologies, the hydraulic pump station for injection molded parts with heat dissipation components provided by this utility model has the following beneficial effects: This utility model provides a hydraulic pump station for injection molded parts with a heat dissipation component. When using the hydraulic pump station, the system is started via the control cabinet. The motor drives the hydraulic pump body to draw oil from the tank through the oil delivery pipe and pressurize it. The pressurized oil is then delivered to the control valve through another oil delivery pipe to execute actions. Under the control of the control valve, the pressurized oil is delivered to the actuator through the oil delivery pipe, driving its operation. The low-pressure oil discharged by the actuator flows back to the tank, forming a closed loop. When the hydraulic pump station starts or the motor temperature rises, the control cabinet issues a command to start the heat dissipation system. The fan is powered on and begins to rotate, generating initial airflow. This initial airflow enters a constricted air duct, whose constricted structure concentrates the airflow, significantly increasing its velocity and impact force, preparing for long-distance delivery and efficient heat dissipation. The airflow then enters the ventilation pipe, and a fixing rod fixed to its arc surface ensures the ventilation pipe remains stable under the impact of the airflow, preventing vibration. The airflow then enters the delivery pipe from the ventilation pipe. The delivery pipe acts as an airflow distribution hub, distributing airflow to multiple extension pipes. Simultaneously, the drive motor starts under control cabinet commands, rotating the rotating rod and turntable. One end of the adjusting rod is eccentrically mounted on the turntable. As the turntable rotates, the adjusting rod is moved along the inner wall of the turntable, while the sliding sleeve at the end of the adjusting rod is fitted onto the connecting rod. The movement of the adjusting rod forces the sliding sleeve to slide back and forth on the connecting rod, simultaneously pushing the connecting rod to reciprocate with its connecting blocks at both ends as fulcrums. The Teflon anti-jamming sleeve on the connecting rod ensures smooth and unobstructed sliding-swinging motion, preventing jamming. The swinging motion of the connecting rod is transmitted to the delivery pipe through the connecting blocks, causing the entire delivery pipe and all its extension pipes to continuously swing back and forth within a small angle range. Airflow is blown out from the funnel-shaped duct at the end of each swinging extension pipe. Because the air outlet continuously sweeps left and right, the cooling air is no longer fixed to a single point, but rather scans and covers the entire surface of the motor like a fan, achieving uniform heat dissipation without dead angles and effectively preventing localized overheating. Meanwhile, the heat sink, which is closely attached to the motor casing, continuously conducts heat from inside the motor and dissipates it into the air, further improving heat dissipation. The vibrations and noise generated by the motor and cooling system are absorbed and isolated by the rubber sound insulation plate inside the support plate, reducing overall operating noise. By operating the cooling device, better heat dissipation for the motor is achieved. Attached Figure Description

A rotating rod 709 is fixedly connected to the output end of the drive motor 708. A turntable 710 is fixedly connected to one end of the rotating rod 709. An adjusting rod 711 slides through the inner wall of one side of the turntable 710. A sliding sleeve 712 is fixedly connected to one end of the adjusting rod 711. A connecting rod 713 is movably connected to the inner wall of the sliding sleeve 712. A connecting block 714 is fixedly connected to both ends of the arc surface of the connecting rod 713. The inner walls of the two connecting blocks 714 are fixedly connected to the same conveying pipe 704. Several extension pipes 716 are fixedly connected to one side of the conveying pipe 704. The heat dissipation device 7, via the control cabinet 6, causes the fan 701 to generate cooling airflow. This airflow is accelerated through the constricted air duct 702 and then enters the ventilation pipe 703 and the delivery pipe 704. The drive motor 708 then rotates the rotating rod 709, causing the turntable 710 to rotate. This causes the adjusting rod 711 to move along the inner wall of the turntable 710 while being carried by it. The sliding sleeve 712 is oscillating as it slides on the connecting rod 713. The connecting block 714 causes the delivery pipe 704 to rotate back and forth within the support ring 705. In this way, several extension pipes 716 oscillate back and forth, blowing air evenly onto the motor 2, achieving dynamic heat dissipation, expanding the heat dissipation area, effectively preventing overheating of the motor 2, and improving the operational stability of the hydraulic pump station. An anti-jamming sleeve 715, made of Teflon, is fixedly connected to the arc surface of the connecting rod 713. The anti-jamming sleeve 715 utilizes the low-friction properties of Teflon material to reduce the frictional resistance of the connecting rod 713 during movement, preventing jamming between the connecting rod 713 and the sliding sleeve 712, ensuring smooth swing of the conveying pipe 704, and improving the reliability and service life of the heat dissipation device 7. Several heat sinks 718 are fixedly connected to one side of the inner wall of the support plate 707, and one side of each heat sink 718 is fixedly connected to the same motor 2. The metal heat sinks 718 quickly conduct the heat generated by the motor 2 to the support plate 707 and dissipate it into the surrounding air, enhancing the heat dissipation effect and helping to reduce the temperature of the motor 2. A sound insulation plate 719, made of rubber, is fixedly connected to one side of the inner wall of the support plate 707. The sound insulation plate 719 utilizes the elasticity and sound absorption properties of rubber material to absorb the vibration and noise generated by the motor 2 during operation, reducing noise pollution in the working environment, improving operational comfort and the environmental friendliness of the equipment.A fixing rod 720 is fixedly connected to the arc surface of the ventilation duct 703, and one end of the fixing rod 720 is fixedly connected to the oil tank 1. The fixing rod 720 firmly fixes the ventilation duct 703 to the oil tank 1, preventing the ventilation duct 703 from shifting or loosening due to airflow impact or equipment vibration, ensuring the stability of the airflow channel and guaranteeing continuous and efficient delivery of cooling airflow. One end of the extension pipe 716 is fixedly connected to a funnel-shaped air duct 717, which is flared. The flared design of the funnel-shaped air duct 717 increases the airflow outlet area, allowing the cooling airflow to diffuse more evenly to the surface of the motor 2, avoiding local overheating, improving the heat dissipation coverage and efficiency, while reducing airflow resistance and optimizing airflow distribution. The working principle of the hydraulic pump station with heat dissipation component provided by this utility model is as follows: When using the hydraulic pump station, the system is started through the control cabinet 6. The motor 2 drives the hydraulic pump body 3 to draw oil from the oil tank 1 through the oil supply pipe 4 and pressurize it. The pressurized oil is delivered to the control valve 5 through another oil supply pipe 4 to perform the action. The pressurized oil is delivered to the actuator through the oil supply pipe 4 under the control of the control valve 5, and drives it to act. The low-pressure oil discharged by the actuator flows back to the oil tank 1, forming a closed loop. When the hydraulic pump body 3 starts or the motor 2 temperature rises, the control cabinet 6 issues a command to start the cooling system. The fan 701 is energized and starts rotating, generating initial airflow. The initial airflow enters the constricted air duct 702, and the constricted structure of the air duct 702 concentrates the airflow, significantly increasing its velocity and impact force, preparing for long-distance delivery and efficient heat dissipation. Then the airflow enters the ventilation pipe 703, and the fixing rod 720 fixed on its arc surface ensures that the ventilation pipe 703 remains stable under the impact of the airflow and does not vibrate. The airflow enters the delivery pipe 704 from the ventilation pipe 703. The delivery pipe 704 acts as an airflow distribution hub, distributing the airflow to multiple extension pipes 716 on it. At the same time, the drive motor 708 starts under the command of the control cabinet 6, and the drive motor 708 drives the rotating rod 709 and the turntable 710 to rotate. One end of the adjusting rod 711 is eccentrically mounted on the turntable 710. As the turntable 710 rotates, the adjusting rod 711 is moved along the inner wall of the turntable 710 while being carried by the turntable 710. The sliding sleeve 712 at the end of the adjusting rod 711 is fitted onto the connecting rod 713. The movement of the adjusting rod 711 forces the sliding sleeve 712 to slide back and forth on the connecting rod 713, while simultaneously pushing the connecting rod 713 to swing back and forth with the connecting blocks 714 at both ends as fulcrums. The Teflon anti-jamming sleeve 715 on the connecting rod 713 ensures this sliding-swinging motion. The smooth and unobstructed movement prevents jamming. The swing of the connecting rod 713 is transmitted to the conveying pipe 704 through the connecting block 714, causing the entire conveying pipe 704 and all its extension pipes 716 to swing back and forth continuously within a small angle range. Airflow is blown out from the funnel-shaped air duct 717 at the end of each swinging extension pipe 716. As the air outlet continuously sweeps left and right, the cooling air is no longer blown fixedly to one point, but rather scans and covers the entire surface of the motor 2 like a fan, thereby achieving uniform heat dissipation without dead angles and effectively preventing local overheating. At the same time, the heat sink 718, which is close to the outer shell of the motor 2, continuously conducts heat from inside the motor 2 and dissipates it into the air, further improving heat dissipation. The vibration and noise generated by the motor 2 and the cooling system are absorbed and isolated by the rubber sound insulation plate 719 on the inner side of the support plate 707, reducing the overall operating noise.
