Maintenance methods and precautions about injection molding machine 

1. When installing the new machine, the level of the machine must be adjusted and leveled, and the level of the machine should be re-adjusted three times in the third month, six months, and one year after the installation and adjustment to prevent new foundations. , The new machine is displaced during operation, causing damage to the machine.

2. The mechanical parts of the new machine need to be run-in. Within three months of normal production, the machine lubrication interval modulus setting should not exceed 100 modules. After three months, the modulus can be set according to the service cycle, but each lubrication point must be guaranteed. Every bit must be oily to prevent drying at each point so that the mechanical parts can be fully lubricated. When the lubricating oil in the lubricating oiler is used up, pay attention to the type of lubricating oil to be filled, so as not to use improper lubricating oil and cause damage to the machine. The lubricating oil for normal use is marked on the oiler, please check the instructions in detail.

3. It is recommended to use 46# hydraulic oil for hydraulic oil, and replace the new hydraulic oil after the new machine is used for half a year to prevent possible impurities in the oil circuit of the new machine from jamming the control valves.

4. Voltage stability: To maintain the stability of the power consumption of the customer's factory, the upper and lower voltage deviation should not exceed 20V, and the wiring of the zero line and the ground line must be complete.

5. The hydraulic oil must be replaced once a year and the oil tank must be cleaned, and the oil filter element must be replaced once a year.

6. Cooling water supply system: the water pressure of the cooling water system is 0.2~0.6Mpa; the water connection of the machine cooler must go in and out.

The injection molding machine is composed of machinery, hydraulics, electrical appliances, special accessories, etc., which are organically combined according to the needs of the injection molding process technology. If a component of the injection molding machine fails, it will cause a shutdown.

The injection molding machine has large investment in fixed assets, large production scale, large consumption of raw materials, high labor productivity, and large output value. It is a form of production organization with high labor efficiency.

Although the operation of the injection molding machine is simple and the number of workers is small, the management and maintenance of the injection molding machine has a high technical content and a large workload.

Therefore, to ensure that the injection molding machine is always in good condition, it is necessary to strengthen the management of the injection molding machine and strictly control the failure of the injection molding machine. In order to achieve the purpose of reducing the failure rate, reducing maintenance costs and prolonging the service life.

What should we do if it is over high temperature?

(1) According to different load requirements, check and adjust the pressure of the relief valve frequently to make it just right. 

(2) Reasonable selection of hydraulic oil, especially oil viscosity, when conditions permit, try to use a lower viscosity to reduce viscosity friction loss. 

(3) Improve the lubricating conditions of moving parts to reduce friction loss, which is conducive to reducing workload and heat generation. 

(4) Improve the assembly quality and precision of hydraulic components and hydraulic systems, strictly control the fitting clearance of fittings and improve lubrication conditions. The sealing material with small friction coefficient and the improved sealing structure are used to reduce the starting force of the hydraulic cylinder as much as possible to reduce the heat generated by the mechanical friction loss.
