GUANGDONG SHIMI INTELLIGENT EQUIPMENT CO.,LTD
SHIMI DC350 TON Aluminum Die Casting Machine Cold Chamber Machine
Features and Configuration
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 double-toggle connecting rod five-point expansion structure to provide strong clamping force.
The clamping action is divided into multi-level pressure and speed control and low-pressure clamping protection function.
Double-cylinder hydraulic ejection design 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.
The fixed plate and moving plate are equipped with mold cooling water contacts, which are convenient for installation and operation.
Hydraulics
Adopt fast differential regeneration clamping oil circuit system, the opening and clamping action runs smoothly and quickly, and improves production efficiency.
Equipped with abundant hydraulic core-pulling groups, 1 group of hydraulic core-pulling valve shaping plate and 1 group of moving plate are standard; 2 sets of shaping plates and moving plates can be selected each.
There is a set of fixed molds and moving molds, which are designed for molds with special requirements to improve the air tightness and strength of die castings.
Double-cylinder hydraulic ejection design provides balanced ejection force and reduces the factors of product ejection deformation.
Use reliable brand hydraulic components (Tokyo, Yuken, etc.).
Injection system
Two independent high-speed and booster accumulators are adopted, each with sufficient storage capacity, and the high-speed and pressurization do not affect each other to ensure stable injection force.
The slow injection is controlled by an electric proportional valve, which is sensitive and stable.
The injection action is controlled by multi-stage speed, which is suitable for various mold product process requirements.
Wide injection speed adjustment range, slow injection speed 0.1-1.4m/s.
High-speed injection: The maximum air injection speed >= 8.5m/s. Guarantee of high-quality castings.
Active check pressurization system: short pressure construction time, small pressure impact, high repeatability. It is suitable for the production of high-density castings.
Built-in pressurized piston 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.
Dual-proportional control hydraulic power system
Dual-proportional control of the hydraulic system, intelligent dynamic operation, clear high-pressure throttling, reduce oil temperature.
Dual 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.
Electrical control systems
Siemens control system and Siemens touch screen, easy to control, rich function pages, to meet the control of die-casting process.
Powerful parameter storage function, up to 60 sets of mold parameters can be stored, 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 outer steel wire protection wire. Even in harsh environments, it is well protected to ensure normal production.
The line connecting the fuselage and the main control box adopts aviation plug, which is safe and reliable, and easy to maintain.
- Siemens PLC Controller
