Safety knowledge of injection molding machine
Injection molding machine
Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into plastic products of various shapes using plastic molding dies. Divided into vertical, horizontal, all-electric. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity.
Injection molding machine usually consists of injection system, Bakelite Injection Molding Machine mold clamping system, hydraulic transmission system, electrical control system, lubrication system, heating and cooling system, safety monitoring system, etc.
The role of the injection system: The injection system is one of the most important components of the injection molding machine. Generally, there are three main forms of plunger, screw, and screw pre-plastic plunger injection. Currently the most widely used is the screw type. Its function is that in a cycle of the injection molding machine, a certain amount of plastic can be heated and plasticized within a specified time, and the molten plastic is injected into the mold cavity through a screw under a certain pressure and speed. After the injection is completed, the molten material injected into the mold cavity is maintained in shape.
Composition of the injection system: The injection system consists of a plasticizing device and a power transmission device.
The plasticizing device of the screw-type injection molding machine is mainly composed of a feeding device, a barrel, a screw, Plastic Machinery Manufacturing and Sales a rubberized component and a nozzle. The power transmission device includes an injection oil cylinder, an injection seat moving oil cylinder, and a screw drive device (melt motor).
The role of the clamping system: the function of the clamping system is to ensure that the mold is closed, opened and ejected. At the same time, after the mold is closed, the mold is provided with sufficient clamping force to resist the cavity pressure generated by the molten plastic entering the mold cavity, preventing the mold from cracking, which causes the defective status of the product.
The composition of the mold clamping system: The mold clamping system is mainly composed of a mold clamping device, a machine winch, a mold adjustment mechanism, an ejection mechanism, a front and rear fixed template, a mobile template, a mold clamping cylinder and a safety protection mechanism.
The function of the hydraulic transmission system is to realize that the injection molding machine provides power according to the various actions required by the process, and meets the requirements of the pressure, speed, temperature and other parts of the injection molding machine. It is mainly composed of various kinds of hydraulic components and hydraulic auxiliary components, of which the oil pump and motor are the power source of the injection molding machine. Various valves control oil pressure and flow to meet the requirements of the injection molding process.
The electric control system and the hydraulic system can cooperate reasonably to realize the process of the injection machine.

There are many ways to format text! You can make text bold, you can make text italic, or you can use
strikeout or underline options. Text can be BIG or small. Want text in a different color like red or blue?
You can even c o m b i n e the options.
“Block quotes are a great way to emphasize text.”

Paragraph and List Formatting
The default setting for paragraph text is left-aligned, non-justified text.
If you'd like, you can use right-aligned text.
Or even center-aligned text.
You can also justify text which fills in all of the horizontal space for a paragraph. When using this setting, your text will always fill in left to right for anything but the last line of a paragraph, just like you see in magazines and newspapers. This paragraph is a bit long, and it's just here to show you an example of justified text.
Want to create a numbered list?
- You can talk about one fish.
- Two fish.
- Perhaps even red fish or blue fish.
Bulleted lists are fun too.
- You can created a list of items.
- Add as many items as you'd like.
- You can even nest lists by pressing the Tab key on your keyboard.
- But wait, there's more!
