Shoe Sole Manufacturing Instructions

Developing good shoe sole injection molding machine operating habits is of great benefit to improving machine life and production safety.

Before starting up:

(1) Check whether there is water or oil entering the electrical control box. If the electrical appliance is damp, do not turn it on. Maintenance personnel should blow dry the electrical parts before turning on the machine.

(2) Check whether the power supply voltage is consistent, which should generally not exceed ±15%.

(3) Check whether the emergency stop switch and front and rear safety door switches are normal. Verify that the rotation directions of the motor and oil pump are consistent.

(4) Check whether each cooling pipe is smooth, and pass 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 moving part, and add enough lubricating oil.

(6) Turn on the electric heat to heat each section of the barrel. When the temperature of each section reaches the requirement, keep it warm for a period of time to stabilize the machine temperature. The holding time varies according to the requirements of different equipment and plastic raw materials.

(7) Add enough plastic to the hopper. According to the requirements for injection molding of different plastics, some raw materials are best dried first.

(8) Cover the heat shield on the barrel, which can save electric energy and extend the life of the electric heating coil and current contactor.

During operation:

(1) Do not cancel the function of the safety door at will just for the sake of convenience.

(2) Pay attention to the temperature of the pressure oil and do not exceed the specified range. The ideal working temperature of hydraulic oil should be maintained between 45~50℃, and generally the range of 35~60℃ is more suitable.

(3) Pay attention to adjusting each stroke limit switch to avoid collision when the machine moves.

At the end of the work:

(1) Before stopping the machine, the plastic in the barrel should be cleaned to prevent the remaining materials from oxidizing or decomposing due to long-term heat.

(2) The mold should be opened to keep the toggle mechanism in a locked state for a long time. (3) The workshop must be equipped with lifting equipment. Great care should be taken when assembling and disassembling bulky parts such as molds to ensure production safety.
