Famolavolana Injection milina fototra

Ny rafitry ny tsindrona tsindrona dia tena zava-dehibe ho an'ny mpandraharaha.

According to the requirements of the fomba fanamboarana tsindrona, Ny milina mamolavola tsindrona dia modely misy mechatronika matanjaka. Izy io dia ahitana ny ampahany amin'ny tsindrona, Fehezanteny fizarana, fuselage, System hydraulic, rafitra fanafanana, rafitra fanaraha-maso, Fitaovana famahanana, sns. Amin'izao, Ny fitaovana tsindrona sofina mahazatra dia manana karazana cylinder tokana sy karazana cylinder roa. There are two types of plasticized parts: plunger type and screw type. In the continuous pushing process of the rotating screw, the plastic realizes the change of the physical state, and finally is in the molten state and is injected into the mold cavity. Ary noho izany, the plasticized part is the core part to complete uniform plasticization and realize quantitative injection. So what are the most basic structures of injection molding machines? Let’s take a look together:

1. Injection molding system

The function of the injection system: The injection system is one of the most important components of the injection molding machine. ankapobeny, there are three main forms: karazana plunger, karazana visy, and screw preplasticized plunger injection type.

Amin'izao, the most widely used is the screw type. Its function is that in a cycle of the plastic injection machine, ny habetsaky ny plastika dia azo hafanana sy plastika ao anatin'ny fotoana voafaritra, and the molten plastic can be injected into the mold cavity through a screw under a certain pressure and speed. After the injection, the molten material injected into the mold cavity is kept in shape. ny

The composition of the injection system: the injection system is composed of a plasticizing device and a power transmission device.

The plasticizing device of the screw injection molding machine is mainly composed of a feeding device, barika, visy, ary nozzle. Ny fitaovana fampitana herinaratra dia misy cylinder tsindrona, an injection seat moving cylinder, and a screw drive device (melting motor).

2. Mold clamping system

The role of the clamping system: the role of the clamping system is to ensure that the mold is closed, opened and ejected. Mandritra izany fotoana izany, after the mold is closed, sufficient clamping force is provided to the mold to resist the cavity pressure generated by the molten plastic entering the mold cavity, and prevent the mold from opening seams, resulting in a bad status of the product. Composition of the mold clamping system: The mold clamping system is mainly composed of a mold clamping device, a mold adjustment mechanism, an ejection mechanism, a front and rear fixed template, a movable template, a mold clamping cylinder, and a safety protection mechanism. ny

3. rafitra hydraulic

The function of the hydraulic transmission system is to realize the injection molding machine to provide power according to the various actions required by the process, and to meet the requirements of pressure, hafainganam-pandeha, hafanana, sns. required by each part of the injection molding machine. It is mainly composed of various hydraulic components and hydraulic auxiliary components, among which the oil pump and the motor are the power source of the injection molding machine. Various valves control the oil pressure and flow rate to meet the requirements of the injection molding process.

4. Electrical control system

The electrical control system and the hydraulic system are reasonably coordinated to realize the process requirements (tsindry, hafanana, hafainganam-pandeha, Time) and various program actions of the injection machine. It is mainly composed of electrical appliances, electronic components, meters, fanafanana, sensors, sns. There are generally four control modes, BOKY, semi-automatic, fully automatic, and adjustment. ny

5. Heating/cooling system

The heating system is used to heat the barrel and the injection nozzle. The barrel of the injection molding machine generally uses an electric heating ring as a heating device, which is installed on the outside of the barrel and is detected in sections by a thermocouple. The heat conducts heat conduction through the wall of the cylinder to provide a heat source for the plasticization of the material; the cooling system is mainly used to cool the oil temperature. Excessive oil temperature will cause a variety of faults, so the oil temperature must be controlled. The other location that needs to be cooled is near the feeding port of the feed pipe to prevent the raw material from melting at the feeding port, causing the raw material to fail to be fed normally.

6. Lubrication system

The lubrication system is a circuit that provides lubrication conditions at the relative moving parts of the injection molding machine’s movable template, mold adjustment device, connecting rod hinge, Sns, in order to reduce energy consumption and increase the life of parts. Lubrication can be regular manual lubrication or Automatic electric lubrication;

7. Security protection and monitoring system

The safety device of the milina fanaovana tsindrona is mainly used to protect the safety of people and machines. It is mainly composed of safety doors, hydraulic valves, limit switches, photoelectric detection elements, Sns, to achieve electrical-mechanical-hydraulic interlock protection.

The monitoring system mainly monitors the oil temperature, material temperature, system overload, and process and equipment failures of the injection molding machine, ary manondro na manaitaitra rehefa misy toe-javatra tsy mety.
