Hydraulic Power System for Precision LED Lens Molding Machine

Product Specifications

Technical details and manufacturing context for Hydraulic Power System

Definition

The hydraulic power system is a critical component of the Precision LED Lens Molding Machine, responsible for generating, regulating, and delivering high-pressure hydraulic fluid to various actuators. It ensures precise and repeatable force application during the molding cycle, including mold clamping to withstand injection pressure, controlled injection of molten plastic, and part ejection, which is essential for producing high-quality, optically precise LED lenses with consistent dimensions and minimal flash. The system typically comprises an electric motor, hydraulic pump, reservoir, control valves, and associated piping. It operates within specified parameters such as operating pressure of 1.0–1.6 MPa, flow rate of 20–60 L/min, power output of 5.5–15 kW, and tank capacity of 100–300 L. Pressure accuracy is maintained within ±0.5%, and the system is designed for a supply voltage of 380–480 V AC (IEC 60038) and control voltage of 24 V DC ±10%. Operating temperature range is 5–50 °C, with fluid temperature maintained at 30–60 °C for optimal viscosity. The system offers ingress protection of IP54–IP65 (IEC 60529) and noise levels of 65–75 dB(A) (ISO 3744). Physical characteristics include a weight of 300–800 kg and dimensions ranging from 1200×800×1500 mm to 2000×1200×1800 mm. Materials used include hydraulic oil, carbon steel, alloy steel, and seals (NBR/FKM). These values are reference ranges for directory purposes and must be verified with the legal manufacturer for specific models and applications.

Working Principle

An electric motor drives a hydraulic pump to pressurize hydraulic fluid (oil) from a reservoir. This pressurized fluid is directed through control valves (such as directional, pressure, and flow control valves) to hydraulic cylinders or motors. The system uses feedback from pressure sensors and position transducers to maintain precise control over force, speed, and position of the molding machine's platens and screw, enabling the high-precision requirements of LED lens production.

Components / BOM

Hydraulic Pump
Converts mechanical energy from the motor into hydraulic energy by pressurizing the fluid.

Material: Alloy Steel
Hydraulic Reservoir
Stores hydraulic fluid, allows for heat dissipation, and helps separate air and contaminants from the fluid.

Material: Carbon Steel
Directional Control Valve
Directs the flow of hydraulic fluid to control the movement (extend/retract) of hydraulic cylinders.

Material: Carbon Steel/Alloy Steel
Pressure Relief Valve
A safety component that limits the maximum pressure in the system by diverting excess fluid back to the reservoir.

Material: Alloy Steel
Hydraulic Cylinder
Converts hydraulic pressure into linear mechanical force and motion to perform clamping, injection, and ejection.

Material: Hardened Steel
Electric Motor
Drives the hydraulic pump; it is the system's prime mover.
Flow Control Valve
Sets actuator speed by metering flow, which is how injection and clamping speeds are dialed in.
Pressure Sensors and Position Transducers
Feed actual pressure and platen/screw position back so force, speed and position can be held precisely.
