Matters needing attention in the injection molding operation process of injection molding machine inserts

What should the injection molding machine pay attention to during the operation of insert injection molding? Develop good operating habits, which is conducive to improving the life of the machine and equipment and production safety/safety. The stamping manufacturer should strictly follow the relevant standards and implementation rules. Achieve scientific management, correct use, reasonable lubrication, careful maintenance, regular maintenance, planned overhaul, improve the equipment integrity rate, and keep the equipment in good condition. Let's take a look at the precautions below. 1. Before starting up: (1) Check whether there is water or oil in the electrical control box. If the electrical appliance is damp, do not switch it on. The electrical parts should be blown dry by maintenance personnel before turning on the machine. (2) Check whether the power supply voltage is in compliance, generally should not exceed ±15%. (3) Check whether the emergency stop switch, front and rear safety/full door switches are normal. Verify that the rotation direction of the motor and the oil pump are the same. (4) Check whether the cooling pipes are unblocked, and pour cooling water into the oil cooler and the cooling water jacket at the end of the barrel. (5) Check whether there is lubricating oil (grease) in each movable part, and add enough lubricating oil. (6) Turn on the electric heater and heat each section of the barrel. When the temperature of each section reaches the requirements, keep it warm for a period of time to stabilize the temperature of the machine. The holding time varies according to the requirements of different equipment and plastic materials. (7) Add enough plastic in the hopper. According to the requirements of different plastics for injection molding, some raw materials must be dried first. (8) Cover the heat shield on the barrel, which can save power and extend the life of the electric heating coil and current contactor. 2. During the operation: (1) Don't cancel the security/full gate function at will for convenience. (2) Pay attention to the temperature of the pressure oil, and the oil temperature should not exceed the specified range. The ideal working temperature of hydraulic oil should be kept between 45~50℃, generally within the range of 35~60℃. (3) Pay attention to adjusting each stroke limit switch to avoid impact when the machine moves. 3. At the end of the work: (1) Before stopping the machine, the plastic in the barrel should be cleaned to prevent oxidation of the leftover material or long-term thermal decomposition. (2) The mold should be opened to keep the toggle mechanism in a locked state for a long time. (3) The workshop needs to be equipped with lifting equipment. Care should be taken when assembling and disassembling heavy parts such as molds to ensure production safety.
