The horizontal injection molding machine may encounter various faults in the production process, which will not only affect the production efficiency, but also may lead to substandard product quality. Today, Liansheng injection molding machine Xiao Bian will introduce common faults and solutions of horizontal injection molding machine.

1. The pressure of the injection molding machine is unstable

Possible causes: the oil temperature of the hydraulic system is too high; The hydraulic oil is polluted or the oil quality is unqualified; There is oil leakage in the hydraulic system. Solution: regularly check the oil temperature of the hydraulic system and keep it at a suitable working temperature; Replace the hydraulic oil regularly to ensure that the oil quality meets the requirements; Regularly check the hydraulic system pipeline and repair the problem of oil leakage.

2. The mold does not open and close smoothly

Possible causes: insufficient lubrication; Mold parts are damaged or worn; The quality of lubricating oil is poor.

Solution: increase the supply of lubricating oil to ensure adequate lubrication; Check the mold parts regularly and replace them in time if any problems are found; Use high-quality lubricating oil to avoid poor operation of the mold due to oil quality problems.

3. Inaccurate temperature control

Possible cause: heater failure; Temperature controller setting error; Cooling system failure.

Solution: Check the heater regularly to ensure its normal operation; Carefully adjust the setting of the temperature controller to keep it within the temperature range required for production; Check the cooling system regularly to prevent inaccurate temperature control due to insufficient cooling.

4. The hopper is blocked

Possible cause: excessive humidity of raw materials; Improper hopper design; There is foreign matter in the hopper.

Solution: control the humidity of raw materials to ensure that it is within the appropriate range; Redesign the hopper to ensure the smooth flow of raw materials; Clean the hopper regularly to prevent foreign matters from blocking.

5. Electrical system fault

Possible cause: loose cable connection; Aging of electrical components; The electrical system design is unreasonable.

Solution: Regularly check the cable connection to ensure that the connection is firm; Regularly replace aging electrical components; Optimize electrical system design and improve system stability.

Through timely troubleshooting and maintenance, it can effectively improve Horizontal injection molding machine Production efficiency and product quality to ensure the smooth progress of the production process. The production and operation personnel should have certain mechanical and electrical knowledge to better cope with and solve various failures and ensure the normal operation of the horizontal injection molding machine.
