280TON Automatic Hot Chamber Die Casting Machine for Zinc Alloy Zamac Lead
Zinc Alloy Hot Chamber Die Casting Machine 280Ton for Making Door Handle
Features and Configuration
Injection system
An independent high-speed accumulator is adopted, which has sufficient storage capacity to ensure stable injection force.
The slow injection speed can be controlled individually, with sensitive response and smooth action.
The injection action is controlled by a certain speed, with a specific hydraulic system, which is suitable for various product process requirements with high surface requirements.
Wide range of injection speed adjustment.
The maximum air injection speed of high-speed injection is stable, which is the guarantee of producing high-quality castings.
Low hydraulic impact, high repeatability, suitable for the production of high density castings.
Piston energy storage structure improves action response, improves the integrity of the injection system, and reduces oil leakage points.
Multi-injection position lifting, suitable for the production of molds with different structures.
Hydraulic System
Adopt fast differential regeneration clamping oil circuit system, the opening and clamping action runs smoothly and quickly, and improves production efficiency.
Standard configuration of hydraulic core-pulling valve moving pattern plate 1 group.
Use reliable brand hydraulic components (Tokyo, Yuken, etc.).
Electrical control systems
Powerful parameter storage function, which is convenient for future production call, improves production efficiency, and maintains consistent product quality.
The fuselage line is made of oil-resistant and temperature-resistant and covered steel wire protection wires, which are well protected even in harsh environments to ensure normal production.
The unique position selection of rotary blanking hopper can be used by customers to choose a better blanking method according to the plant situation.
Servo drive and single proportional control hydraulic power system
Intelligent dynamic operation, high energy saving rate, clear high pressure throttling, reduce oil temperature.
Servo drive has fast response speed.
Single-proportional control of the hydraulic system, intelligent dynamic operation, clear high-pressure throttling, reduce oil temperature.
Single-proportional control hydraulic system, pressure and speed can be adjusted.
Improve the stability of the whole machine and ensure the product quality.
Flexible and smooth action conversion, reduce the impact of action, and prolong the service life of machinery and molds.
Clamping system
Four large bar guide pillars, using high-tensile steel as raw materials, the surface is hardened by high-frequency heat treatment, and the outer layer is re-plated with hard chrome, which has high wear resistance and prolongs the service life of the machinery.
The three major formwork and machine hinges are made of high-strength ductile iron, and the five-point expansion structure of the toggle connecting rod provides strong clamping force.
The clamping action is divided into multi-level pressure and speed control and low-pressure clamping protection function.
The hydraulic ejection design of the cylinder provides balanced ejection force and reduces the factors of product ejection deformation.
Adopt central electric lubrication system, advanced point-by-point quantitative lubrication. Ensure that the lubrication points near and far are evenly lubricated, and there are liquid level and pressure alarm functions to ensure the good lubrication effect of the machine.
Automatic centralized lubrication system
Central automatic lubrication system, timing lubrication toggle to improve mechanical life and reduce maintenance.
Synchronous belt drive is adopted, which has the advantages of silence, fast speed, long service life and low maintenance cost;
Humanized operation, unique front and rear double operating tables, improve the convenience of operation:
The PLC control system is used to modify various adjustment parameters through the man-machine interface, and has the function of fault diagnosis, and the man-machine interface can display the fault content, which is convenient to quickly deal with the fault abnormality;
Infrared photoelectric switch detection function, no detection of product equipment stop operation, to ensure the safety of the mold;
Strengthened fuselage structure, mechanical rigidity and stable effect;
The rear side of the die-casting machine is equipped with an automatic protective door to ensure the safety of operators and equipment.
