3.1.4 Check the mold fastening bolts and travel switches, whether the mechanical safety lever is adjusted in place, whether the safety door is flexible and reliable;
3.1.5 Check the raw materials for foreign substances and impurities before feeding;
3.2 Start-up
3.2. 1 After the barrel temperature reaches the process requirements, it should be warmed up for about 10-20 minutes before turning on the machine;
3.2.2 Press the motor start button to start the motor, and wait for it to idle for 2-5 minutes without any abnormal sound before proceeding with the following working procedures;
3.2.3 Close the safety door, press the mold closing switch by manual procedure, and observe the hydraulic gauge reflecting the mold closing switch. switch, observe the hydraulic pressure gauge to reflect the maximum pressure when the mold should be 70KG appropriate, and open the material exposition;
3.2.4 manual injection of glue, the barrel of the front section of the material discharged, and then melting, injection, repeated 3-4 times;
3.2.5 manual table forward, the injection nozzle tightly attached to the mold gates, and will be moved forward and backward of the travel switch limit block press position switch and lock;
3.2.6 set the process parameters of each variety according to the requirements of the process card, press the semi-automatic key, that is, to enter the semi-automatic production state;
3.2.7 according to the setting of the process parameters, the cooling time to the mold to open and eject the product, open the safety gate, take out the product, and then close the door to enter the next cycle;
3.3 Work (safety regulations)
3.3.1 operation must use the safety gate, such as the safety gate travel switch or mechanical safety lever failure, should immediately stop, is strictly prohibited without the use of safety gate operation;
3.3.2 non-shift operator, without the permission of any person is not allowed to press any switches;
3.3.3 molding process abnormalities should be immediately stopped and report to the foreman;
3.3.3 molding process should be found to stop and report to the foreman;
3.3.3 the molding process should be found to stop and report to the foreman. Report;
3.3.4 When the machine is repaired for a long time or the mold is cleaned up, the power supply must be cut off to clean up, and the residual material in the mold (latent mouth, etc.) must be burned out with a copper rod or a steel needle;
3.3.5 The operator is not allowed to take off his post when the maintenance personnel are repairing the machine;
3.3.6 Avoid hitting the fixed mold with the injection molding station when the mold is open to avoid the fixed mold from falling off;
3.3.7 When the nozzle is clogged, it is strictly prohibited to try to shoot out the clogged material by adjusting the injection pressure upward, and it should be dismantled and cleaned up in time;
3.3.8 When it is necessary to put your hand to the range of the mold to work, make sure to stop the oil pump motor first before proceeding;
3.3.9 Do not arbitrarily dismantle, change, or tie up the various safety protection facilities;
3.3.10 Do not touch the movable mold at will while the machine is in normal operation. When the machine is in normal operation, do not touch the moving parts;
3.3.11 It is strictly prohibited to operate the machine with the safety door and other covers open;
3.3.12 In addition to pulling open the safety door to take the product or spraying release agent, it is strictly prohibited to put your hand inside the machine from any direction;
3.3.13 It is strictly prohibited to put any sundry objects on the moving plate in front of the machine cover;
3.3.14 It is strictly prohibited to put any sundry objects on the moving plate in front of the machine cover;
3.3.14 In addition to the device mold, it is strictly prohibited for two people to operate a machine at the same time;4, equipment maintenance plan
4.1 equipment maintenance day plan (completed by the foreman)
4.1.1 once a day to check the temperature of the oil, and line up in time for the failure of the cold water channel;
4.1.2 the activities of the occupation of a day to add at least four times more lubricating oil;
4.1.3 Check whether the screws of each travel switch are loose;
4.1.4 Check whether there is oil leakage from each oil pipe joint;
4.1.5 Clean each part of the body;
4.2 Monthly plan of the maintenance of the equipments (completed by the equipment class)
4.2.1 Check whether there is any loosening of each circuit joint;
4.2.2 Pressure oil Whether clean, check the ink;
4.2.3 whether the oil filter is clogged, cleaned in time;
4.2.4 whether there is a lack of oil at each lubrication point;
4.2.5 checking the oil tank heat dissipation situation, clean the extractor fan, the dust on the dust separator net in time;
4.3 equipment maintenance yearly program
4.3.1 Replacement of pressure oil (In principle, two years need to replace the pressure oil, but must be based on the viscosity of the oil, impurity content and other factors visual inspection
decision);
