¡¤Automatic dosing lubrication system guarantees mould locking mechanism to be more stable and reliable.¡¤Hydraulic motor and centering gear mould adjusting system make mould adjusting system to be better.
Injection Unit
¡¤Superior and efficient separating screw and high mixing screw increase the range of material used, and guarantee molten material to be uniform and stable.
¡¤Injection platform is fixed by double axis pin plus flat key so that it is stable.
¡¤Double cylinder balance injection molten material mechanism provides high-pressure injection of molten material and saves space.
¡¤Machine above BJ400 adopts double injection shift devices to prevent injection nozzle displacement and avoid material leakage.
Features of hydraulic system
¡¤Perfect combination between computer and high efficient proportional plunger variable pump saves electricity by 25%-50%. The economic efficiency is high.
¡¤With full flow filtration oi1 circuit of high precision return oil filter, the oil filter effect is up to NAS ¨C 7 levels, can effectively avoid contamination and deterioration of hydraulic oil, thereby hydraulic parts work more stable and service life of hydraulic seals is longer.
¡¤Imported advanced hydraulic valve incorporated with differential oil circuit guarantees mould locking device to be fast, stable and low noise, and reduces forming period, increase production efficiency.
¡¤Plug-in spill valve adjusts back pressure of molten material. Adjustment range is larger and stable. Product is dense and attractive.
¡¤Spiral flow cooler is high in heat transfer efficiency and less pressure loss. It guarantees stable operation of hydraulic system, improves repetition accuracy and qualification rate of products.
¡¤Low speed and large torque hydraulic motor meets plasticizing demand of different raw material.
Controller
¡¤Advanced switch power supply, with operating voltage between 110V and 280V, can be used in all severe power supply environment.
¡¤High resolution (320x240 color) liquid crystal display is used. It can display 20 columns and 15 lines of Chinese Characters or 40 columns and 15 lines of English letters.
¡¤Complete inspection functions could assist you to adjust each of movement in your machine to its optimum condition.
¡¤It can store injection material information for 120 sets of moulds. Mould information could be selected, duplicated or removed conveniently.
¡¤Six stages material injection speeds and pressure, three stages pressure holding speed and pressure, and two stages material molten speed and pressure control can meet all complicated process requirement of products.
¡¤Fuzzy temperature control is used. High and low temperature deviation alarm and thermocouple disconnection inspection functions are available.
¡¤Function to prevent cold material start-up.
¡¤Mould locking, material injection, thimble adopt high precision electronic meter for position measuring. The position setting precision is up to 0.lmm.
¡¤Push-out stay, thimble shock and multi push-out functions are available. Thimble forward and backward speed, pressure can be set separately.
¡¤Times of forming can be matched with automatic stop function for convenient production management.
¡¤Injection supervision: When machine works in automatic mode, computer may supervise the working condition in each period and judge if products and machine are normal.
¡¤Computer controlled automatic lubrication devices: According to times of opening and clamping mould, lubricating oil output can be adjusted conveniently through computer.
¡¤Automatic mould adjusting function. Input directly mode locking pressure, the computer could automatically finish module thickness adjustment.
¡¤Set information set can be protected so as to prevent improper modification by other personnel.
Features of lubrication system
¡¤Major friction parts are equipped with lubrication points. Central oil supply system is used for hinges. Electric lubricant pump controlled by computer sends automatically lubricating oil (grease) to lubrication points. Lubrication is simple and high efficient.
¡¤Intelligent volumetric centralized lubricating system, controlled by computer, sends quantitatively lubricating oil (grease) to wearing points, and guarantees that the key carrying surfaces are lubricated reliably. The repair is visual, convenient and fast. The service life of the machine is longer.
