Vertical injection molding machine six pieces detailed

 Vertical injection molding machine 6. Detailed six bits and pieces

(1) Injection system

Injection system is one of the most important parts of the injection molding machine, there are plunger type, screw type, screw pre-plastic plunger injection type 3 main ways, vertical injection molding machine is currently the most common use of screw type. Its role is in a plastic injection machine cycle, can be in the regular time a certain amount of plastic heating plasticize, in a certain pressure and speed, through the screw will be injected into the mold cavity molten plastic.

(2) Mold closing system

The function of the mold closing system is to ensure that the mold is closed, opened and ejected products. At the same time, after the mold is closed, enough clamping force is given to the mold to resist the pressure of the mold cavity caused by the molten plastic entering the mold cavity, so as to avoid the mold opening and the bad status of the products. The mold closing system is mainly composed of mold closing installation, mold adjusting mechanism, ejection mechanism, front and rear fixed template, moving template, mold closing cylinder and security maintenance mechanism.

(3) Hydraulic system

The role of hydraulic transmission system is to complete the injection molding machine according to the process requirements of various measures to provide power, and to meet the pressure, speed and temperature requirements of each part of the injection molding machine. It is mainly composed of their respective hydraulic components and hydraulic auxiliary components, in which the oil pump and motor are the power source of injection molding machine. Various valves control the oil pressure and flow, so as to meet the injection molding process requirements.

(4) Electrical control system

The electrical control system and the hydraulic system are coordinated reasonably, which can realize the process requirements (pressure, temperature, speed, time) and various sequence actions of the injection machine. Mainly composed of electrical appliances, electronic components, meters, heaters, sensors and so on. General manual, semi-automatic, automatic, adjustment of four control modes.

(5) Heating/cooling system

The heating system is used to heat the material barrel and the injection nozzle. The material barrel of the injection molding machine generally adopts the electric heating ring as the heating device, which is installed in the inside of the material barrel. The heat conduction through the cylinder wall provides heat source for the plasticization of the material with the segmenting detection of thermocouple. The cooling system is mainly used to cool the oil temperature. Too high the oil temperature will cause a variety of problems, so the oil temperature must be controlled. Another position of cooling demand is near the feeding port of the material pipe, to prevent the melting of the feeding port of the raw material, resulting in the raw material can not be normal feeding.

(6) Smooth system

Lubrication system is the circuit where the absolute motion parts of the dynamic template, mold adjusting device and connecting rod machine hinge of the injection molding machine provide lubrication conditions, so as to increase energy consumption and improve the life of parts. Lubrication can be manual lubrication of current demand or automatic electric lubrication.
