Vertical injection molding machine to develop good habits to improve the life of the machine operation and safety are good.

First, before the vertical injection molding machine boot:

(1) vertical injection molding machine to check whether there is electrical control box, water, oil enter, if electrical damp, do not boot. Maintenance personnel should be dry before turning the electrical parts.
(2) vertical injection molding machine to check whether the supply voltage, generally should not exceed ± 15%.
(3) Check the vertical injection molding machine emergency stop switch, front safety door switch is normal. Verify that the direction of rotation of the motor and pump are the same.
(4) Check the vertical injection molding machine of the cooling pipe is smooth, and the cooling water jacket oil cooler and barrel through the ends of the cooling water.
If (5) Check the vertical injection molding machine all moving parts with a lubricating oil (fat), and add a little oil.
(6) open vertical injection electric heating, for each segment barrel for heating. When the temperature of each meet the requirements, then heat for some time, in order to stabilize the temperature of the machine. Holding time in accordance with the requirements of different devices and plastic raw materials vary.
(7) in the vertical injection molding machine hopper enough to add a little plastic. According to the requirements of different plastics injection molding, some of the materials it is best to go through dry.
(8) To cover the heat shield on the vertical injection molding machine barrel, so you can save energy, and can be extended electric coil and current contactor life.

Second, the process of vertical injection molding machine operations:

(1) Do not for the sake of convenience, free to cancel the role of vertical injection molding machine safety guards.
(2) to observe the temperature of the vertical injection molding machine oil pressure, oil temperature must not exceed the specified range. Hydraulic oil ideal working temperature should be maintained at between 45 ~ 50 ℃, generally in the range of 35 ~ 60 ℃ appropriate.
(3) to adjust the vertical injection molding machine of the travel limit switch, to avoid collision when the machine-generated action.

Third, the end of the vertical injection molding machine at work:

(1) before the shutdown should be vertical plastic injection molding machine to clean the barrel to prevent long-term thermal oxidation or leftover material decomposition.
(2) shall be vertical injection molding machine mold is opened, so that the toggle mechanism in a locked state for a long time.
(3) shop lifting equipment must be provided. Zhuangchai mold and other bulky components should be very careful to ensure production safety.
