Using injection molding machine should pay attention to which a few items

Using injection molding machine's attention point 1. Using injection molding machine must pay attention to safety operation, first check the reliability of the safety door, be sure to keep in mind not to hand when the machine is running into the clamping mechanism, take products, be sure to open the door, after confirm there is no foreign personnel safety or die, to close the door. Hand in the work can't stretch between the nozzle and the mold gate. Repair the mold, it must be close the oil pump motor. Is China the pioneer of injection molding machine research and development and innovation. Continuously improve the injection molding design, and always focus on injection molding machine of improving man-machine interface, high-speed injection molding machine system research and development and stability, precision plastic injection machine filling technology. 2 area, due to the varieties of raw materials, products of different sizes and shapes, the clamping force is different also, when moving mold please the minimum clamping force adjustment according to the actual needs, not only can save power consumption, and will significantly extend the service life of the machine. 3, injection molding machine hydraulic system pressure adjustment shall be carried out according to the requirements of each action, respectively, is unfavorable and exorbitant, reasonably use of pressure, not only can save energy, but also extend the life of the machine. The location of each limit switch, also should adjust according to the needs of manufactured goods, especially in the process of the injection to keep pressure switch point adjustment must pay attention to, or you will make the products molding, on the contrary, lead to products produce the internal stress of high or flash, even cause mold, mold and make it difficult to open. 4, when the injection molding machine screw or when there is no material in the cylinder, unfavorable use high rotational speed of screw, Best under 30 r/min) , wait for material with screw screw groove ( Molten material from the nozzle) when it is squeezed Then the screw rotation speed rise to the need of numerical values. In order to avoid because of idling speed too high or too long scratch screw or cylinder. 5, injection molding machine cylinder heated from room temperature to the required temperature is about 30 minutes. Under the condition of the cylinder with residual cold material, insulation ten minutes again. To activate screw feeding, to ensure that the residual slag fully molten, avoid damage to the screw. 6, injection molding machine, pump, relief valve in the factory has adjusted the, please don't change at will. 7, injection molding machine to run, when the cooling water temperature of 5 c & deg; - 10°c After ( When there is no water in the cooler, you must first make it water filling) And then gradually open the inlet valve of the cooler and in use process to adjust into the water, keep the oil temperature in 55 c & deg; The following. When to start the cooler, bear in mind that quickly open the inlet valve, because a lot of cooling water flows through the cooler, can make the cooler tube surface forming a layer of thermal conductive performance is very poor & other Too cold layer & throughout; , even after a lot of water into the cooler, the result is not good cooling effect. 8, the injection molding machine lubrication, implemented strictly in accordance with the requirements of operation, under the condition of the lack of oil, the serious wear and tear parts, especially the connecting rod and steel set of clamping machine, if the lack of oil may be bite, and unable to work. 9, injection molding machine barrel and screw connection screw part of the heating part plasticization, due to work under high temperature, tear open outfit, threaded portion to besmear hot grease ( Red lead or copper sulfide) To avoid biting * to tear open outfit. 10, the mould installation of injection molding machine template surface has high machining accuracy, please do not use the installation surface and parallel degree of bad mould and bad screw, in order to avoid damage to the template and clamping mechanism performance. 11, injection molding machine, mold installation two plane please don't long time ( More than ten minutes) The mold in the clamping state, lest cause connecting rod pin and steel set off oil, may make the mould to open it. 12, often keep the mutual movement, the surface clean.
