Специфікація машини для лиття під тиском Процес перемикання машини

1. Заходи безпеки під час-увімкнення живлення

① When the machine is running, ensure that the hopper is properly installed and the raw materials are sufficient.

②The safety door must be closed during operation, and the control box and power box must always be closed to prevent dust and impurities from entering the box.

③Do does not remove the protective cover of the plastic melt cylinder at will to prevent burns and electric leakage. Do not stand on the protective cover of the plastic melt cylinder during the inspection.

④It is strictly forbidden to operate the injection or melting action before the temperature reaches the set electric heating temperature value, otherwise, it will cause damage to the screw or oil pipe; the electric heating temperature is indicated by the two signal lights on the temperature controller. The temperature stops; if the temperature is not enough, the green light is on, and the heating is continued.

⑤It is strictly forbidden to use manual injection when the mold is opened and the injection station is not withdrawn, otherwise, the fixed template fixing screw may be damaged or break off the mold; it is also not allowed to manually control the injection station to advance, otherwise, the mold will be ejected. The possibility of falling off.

⑥ It is strictly forbidden to clean the rubber material of the injection nozzle by hand. After the temperature rise of the screw is reached, hands and face are not allowed to approach the injection nozzle. Even if the injection does not start, the air pressure in the barrel can cause the molten rubber to be ejected from the injection nozzle and hurt people.

⑦After using high-temperature decomposition or high-viscosity raw materials, clean the machine and use PE or PP rubber materials. Choose low-pressure and low-speed operations to prevent the rubber from splashing and hurting people during cleaning.

⑧For the machine with a long downtime, it is necessary to exit the injection platform and eject the extremely hot melt in the barrel, otherwise it is easy to cause glue breakage or flashing, and the mold is also easy to be damaged.

2. Етапи операції вимкнення

Під час вимкнення або аварійного вимкнення натисніть червону кнопку аварійної зупинки, щоб вимкнути живлення керування. Нагрівальна частина не зачіпається, а перемикач опалення безпосередньо керує опаленням. Якщо зупинений лише гідравлічний насос, просто натисніть кнопку зупинки гідравлічного насоса. Звичайна процедура вимкнення виглядає наступним чином.

①Close the hopper gate and continue to operate until all the rubber in the barrel is ejected.

②In automatic or semi-automatic operation, the machine will stop the cycle due to lack of material. It can be switched to manual operation mode to discharge all the rubber from the barrel as much as possible to avoid staying in the barrel.

③Open the safety door and the mold, retract the thimble, remove the glued wire or oil rust stains in the mold, and spray anti-rust oil again, and close the mold until the pin is not straight, that is, stop when it exceeds the high-pressure clamping position. Prevent long-term high-pressure mold clamping from deforming the tie rod or difficult to open the mold.
