What are the advantages of the all-electric vertical injection molding machine?

There are many kinds of vertical injection molding machine. Today, we will talk about the all-electric vertical injection molding machine. To know what advantages he has, of course, we must first understand what is his composition structure?

The all-electric injection molding machine is composed of injection molding system, mold closing system, hydraulic system, electrical control system, heating/cooling system, lubrication system, safety protection and monitoring system. Let's take a look at the role each system plays in it.

1. Injection molding system

Role of injection molding system: injection molding system is one of the most important parts of the injection molding machine, generally there are plunger type, screw type, screw pre-plastic plunger injection type 3 main forms. The screw type is widely used at present. 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. After the injection, the molten material injected into the mold cavity is shaped.

Composition of injection molding system: The injection molding system consists of a plasticizing device and a power transmission device. Screw injection molding machine plasticizing device is mainly composed of feeding device, cylinder, screw, nozzle part. The power transfer device includes an injection cylinder, an injection seat moving cylinder and a screw drive device (a glue motor).

2. Mold closing system

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.

Composition of mold closing system: mold closing system is mainly composed of mold closing device, mold adjusting mechanism, ejecting mechanism, front and rear fixed template, moving template, mold closing cylinder and safety protection mechanism.

3. Hydraulic system

The role of hydraulic transmission system is to realize the injection molding machine according to the requirements of the process of various actions to provide power, and to meet the requirements of pressure, speed, temperature and other parts 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 coordinate reasonably, can realize the injection machine process requirements (pressure, temperature, speed, time) and all kinds of program action. 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.

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 on the outside of the material barrel 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.

6, lubrication system

Lubrication system is a circuit where the moving template, mold adjusting device, connecting rod machine hinge and other parts of the injection molding machine have relative movement to provide lubrication conditions, so as to reduce energy consumption and improve the life of parts. Lubrication can be regular manual lubrication or automatic electric lubrication.

7. Safety protection and monitoring system

The safety device of injection molding machine is mainly used to protect the safety of people and machines. It is mainly composed of safety door, hydraulic valve, limit switch, photoelectric detection components, etc., realizing electric-mechanical-hydraulic interlock protection.

The monitoring system mainly monitors the oil temperature, material temperature, system overload, process and equipment faults of the injection molding machine, and gives instructions or alarms when abnormal conditions are found.After knowing the composition of the all-electric single slide injection molding machine, after many tests and operations, we concluded that there are the following advantages:

1, energy saving: because the servo motor is driven directly according to the requirements of the force required by the actuator, it not only improves the efficiency, but also improves the energy utilization rate. The energy utilization rate can reach more than 95%, so it can save 25%-60% energy than the full hydraulic injection molding machine.

2 injection, stable performance, full hydraulic injection molding machine of various dynamic parameters affected by hydraulic oil temperature change and easy hair swings, compared with all dynamic technical parameters of the fully electric injection molding machine basically do not have the interference of external factors, the molding parameters of computer storage is always in line with the actual processing conditions, so the injection performance is stable, fast response, precise injection molding parameters can only be truly reflected on the servo motor system.

3. High efficiency: the application of servo motor improves the reactivity of the system. To a series of fully electric injection molding machine as an example, its forming time is only 1/3 of the fully hydraulic injection molding machine, because electric injection molding machine of each actuator has independent servo motor drive, and not affected by system, so it can be composite action, for example, can be out at the same time, in the process of open mould clamping in plasticizing process at the same time, thus greatly improving the productivity.

4, water saving: because the full electric injection molding machine does not use hydraulic oil, only in the feeding port needs cooling water, so compared with the hydraulic injection molding machine of load sensitive pump, the use of cooling water can be reduced by 70%, compared with the hydraulic injection molding machine of ordinary quantitative pump, cooling water can be reduced by 90%.

5, optimize the working environment: because of the use of hydraulic oil, the working environment can be kept clean, the noise of the machine is more than 10dB lower than the full hydraulic injection molding machine, in the optimization of the working environment at the same time, because of the cancellation of the hydraulic system, so that the injection molding machine accounted for 15% of the area saved.

6, save energy: because each action of the electric injection molding machine is controlled by the corresponding servo motor, so when a production action, other control motors do not need to run, so it greatly saves the power consumption.
