шахах машин үндсэн бүтэц

Тарилгын машин үндсэн бүтэц нь бизнес эрхлэгчдэд үнэхээр чухал юм.

According to the requirements of the шахах хэлбэржүүлэх үйл явц, шахах хэвний машин нь хүчтэй мехатроник бүхий загвар юм. Энэ нь голчлон тарилгын хэсгүүдээс бүрдэнэ, хавчих хэсгүүд, их бие, гидравлик систем, халаалтын систем, удирдлагын систем, тэжээлийн төхөөрөмж, гэх мэт. Одоогоор, нийтлэг чихний тарилгын төхөөрөмж нь нэг цилиндртэй, хоёр цилиндртэй байдаг. 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. Тиймээс, 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. Ерөнхийдөө, there are three main forms: plunger type, screw type, and screw preplasticized plunger injection type.

Одоогоор, the most widely used is the screw type. Its function is that in a cycle of the plastic injection machine, a certain amount of plastic can be heated and plasticized within a specified time, 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. руу

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, баррель, шураг, болон цорго. Цахилгаан дамжуулах төхөөрөмж нь тарилгын цилиндрийг агуулдаг, 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. Үүний зэрэгцээ, 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. руу

3. Гидравлик систем

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, хурд, температур, гэх мэт. 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 (даралт, температур, хурд, цаг) and various program actions of the injection machine. It is mainly composed of electrical appliances, electronic components, meters, халаагч, sensors, гэх мэт. There are generally four control modes, гарын авлага, semi-automatic, fully automatic, and adjustment. руу

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, гэх мэт., 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 шахах хэвний машин is mainly used to protect the safety of people and machines. It is mainly composed of safety doors, гидравлик хавхлагууд, limit switches, photoelectric detection elements, гэх мэт., 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, and indicates or alarms when abnormal conditions are found.
