About 30% of the plastic raw materials in the world are used for injection molding, and injection molding machines account for about 40% of the total output of plastic machinery, and have become an important part of the plastic processing industry and plastic machinery industry, and it is a growth in plastic machinery products. One of the fastest models with the most varieties and specifications and the largest production quantity.
What is the reason for the lack of glue in the injection molding machine, and how to improve it?
How to adjust the injection molding machine speed?
What are the steps of adjusting the injection molding machine speed during the use?
There are three main reasons for the lack of plastic injection mold products:
1. Poor venting of the injection molding machine mold. The so-called poor venting means that when the injection mold is flushed into the mold cavity during the production process, the gas generated in the mold cavity cannot be discharged when it rushes to a certain place, resulting in product production If there is a lack of glue or burnt, you need to send the mold to the mold room master to increase the exhaust of the mold at this time.
2. The plastic inlet of the injection molding machine mold is small. The lack of glue at this time is usually when the new product TO. Due to the first test mold, sometimes the design of the plastic inlet position is too small, which will cause the product to lack glue. At this time, It is necessary to increase the glue inlet, which can generally solve the problem of lack of glue.
3. The pressure of the injection molding machine is not enough. Sometimes the insufficient punching pressure will lead to the problem of lack of glue in the product, and the injection pressure needs to be increased.
First turn on the power and electric heater [set 220 degrees Celsius] and start the motor [stop at 10 seconds interval, 3 times in a row, if there is no abnormality, it can run] start to adjust the parameters of the injection molding machine;
1. Adjust the speed and pressure of the shooting table,
2. Adjust the speed and pressure of the thimble,
3. Adjust the opening and closing speed pressure and position and the low pressure protection pressure speed,
4. Adjust the pressure speed of the injection molding machine,
5. Adjust the clamping high pressure position and clamping pressure.
6. Prepare the material washing machine and select the appropriate temperature required by the material.
7. After the temperature reaches the cold room start prevention time, start washing the machine.
1. First adjust the pressure and speed of the glue pumping and pump the glue,
2. Adjust the injection pressure speed from slow to fast, and inject the glue little by little.
3. Adjust the speed and pressure of the return material (sol) from slow to fast. When returning the material, pay attention to whether the screw of the injection molding machine rotates and feeds normally until the washing machine is completed.
4. After the mold is locked into the injection platform, the test machine is used for trial mold production. First, the spout and then gradually observe how the glue goes in the glue path.
5. Adjust the pressure, speed, time, position and back pressure of the injection glue,
6. Observe the temperature change of the injection molding machine and set the parameters of the mold temperature machine [water temperature 95°, oil temperature 120 to 210°],
7. Forming quality inspection and signing the prototype and production plan to start production.
