The article describes the structure and function of vertical injection molding machine

As a vertical injection molding machine manufacturer, the machine is used in the plastic industry, in the manufacturing country of Dongguan injection molding machine is one of the productive forces, so what is the structural function of vertical injection molding machine? , it is divided and closed mold system - injection system - lubrication system - hydraulic system - electrical control system - heating/cooling system structure!

1. Mold closing system: the mold closing system is mainly composed of mold closing device, mold adjusting mechanism, ejection mechanism, front and rear fixed template, moving template, mold closing cylinder and safety protection mechanism. The function of the mold closing system: the function of the mold closing system is to ensure the mold closing, opening and ejecting products. At the same time, after the mold is closed, enough clamping force can be given to the mold to resist the pressure of the mold cavity caused by the molten plastic entering the mold cavity, so as to prevent the mold opening and cause the bad status of the products.

2. Injection system: the role of the injection system: the injection system is one of the most important components of the vertical injection molding machine, generally there are plunger type, screw type, screw pre-plastic plunger injection type 3 main forms. The screw type is currently the most widely used. Its function is, in a plastic injection machine cycle, can be heated in a specified time a certain amount of plastic plasticized, in a certain pressure and speed, through the screw will be injected into the mold cavity.

3 lubrication system: lubrication system is the vertical injection molding machine template, mold adjustment device, connecting rod machine hinge and other places have a relative movement of the lubrication circuit to provide lubrication conditions, in order to reduce energy consumption and improve the life of parts, lubrication can be regular manual lubrication, can also be automatic electric lubrication.

4. Hydraulic system: the role of the hydraulic transmission system is to realize the injection molding machine according to the process required by the various actions to provide power, and meet the requirements of vertical injection molding machine parts of pressure, speed, temperature, etc. 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.

5. Electrical control system: the electrical control system and the hydraulic system are reasonably coordinated, which can realize the process requirements (pressure, temperature, speed, time) and various program actions of the injection machine. Mainly composed of electrical appliances, electronic components, meters, heaters, sensors and so on. Generally there are four kinds of control mode, manual, semi-automatic, automatic, adjustment.

6. Heating/cooling system: the heating system is used to heat the cylinder and the injection nozzle. The cylinder of the vertical injection molding machine generally adopts the electric heating ring as the heating device, which is installed on the outside of the cylinder and tested by the thermocouple in sections. Heat through the heat conduction of the cylinder wall provides heat source for material plasticization; Cooling system is mainly used to cool the oil temperature, too high oil temperature will cause a variety of failures, so the oil temperature must be controlled. The other place that needs cooling is near the feeding port of the feed pipe to prevent the melting of the feeding port of the raw material, which causes the raw material to be unable to discharge normally.
