| 1, must be taken when using an injection molding machine operating safety, first check the reliability of the safety gate, when the machine is running can not remember them put his hand into the clamping mechanism, while taking products, be sure to open the security door, confirming the safety of personnel or die free of foreign material only after closing the safety door. In operation can not be inserted into the hand between the nozzle and the mold gate. When repair mold, must be shut down pump motor. 2, due to the variety of raw materials, products of different shape and size of the area, the required clamping force is not the same, when the transfer mode, please press the lowest clamping force actual needs adjustment, not only can save power consumption, and significantly prolong machine life. 3, the pressure of injection molding machine hydraulic system should be adjusted according to the requirements of each action separately, not too high, rational use of pressure, not only saves energy, but also extend the life of the machine. The position of each limit switch, should also be adjusted according to the requirements of manufactured goods, especially injection to adjust holding pressure during the switching point must be noted that, otherwise it would be less filling products, on the contrary, lead to products produced within the high stress or burrs, and even lead up mold, leaving the mold is difficult to open. 4, when there is no material in the injection molding machine screw or barrel, it should not be used with high screw speed (preferably at 30 rev / min or less), the raw material to be filled screw grooves (melt extruded from the nozzle) and then screw speed raised to the desired value. So as to avoid idling speed is too high or too long scratch screw or cylinder. 5, injection molding machine barrel is heated from room temperature to the desired temperature takes about thirty minutes. In the cylinder residual cold material circumstances shall be incubated for ten minutes. To start the screw in addition, to ensure that residual material is fully melted the cold, to avoid damage to the screw. |
