1, before work must check whether the bolts are tightly screwed tightly, whether the switch of the operating handle in the empty position, according to the machine tool lubrication charts to add back the amount of oil and lubricant in the lubrication at the lubrication agent; connected to the cooling water and bleed off the air in the oil pipeline, idling operation several times, check whether its transmission and lubrication system is good.
2, according to the different requirements of the product, in general, the adjustment of the machine can be used in slow speed, production is fast.
3, when the machine respectively in the adjustment, manual, semi-automatic, fully automatic four programs, must pay attention to other corresponding switch action position correctness, semi-automatic and fully automatic switching must make its cycle process is complete.
4, the machine tool should be observed to start working to prevent the phenomenon of "creeping".
5, in the screw back operation, must be in the barrel to ensure that the material is fully plasticized state, if the barrel temperature is too low, the barrel temperature must be heated to the plasticizing temperature before proceeding, to avoid damage to the machine tool.
6, the pressure oil coat lubricant should maintain a certain capacity and clean, the pipe should be kept open often.
7, cooling water should be fully guaranteed, do not allow water mixed into the oil, oil temperature is not allowed to exceed 50 ℃.
8, hydraulic system, the maximum pressure can not exceed 0.37MPa.
9, closed mold chain bracing plate mechanism on the two oblique scarf angle is not right, can be properly adjusted on the piston rod on the plate seat on both sides of the nut, so that the oblique fit.
10, the machine tool work, should pay attention to observe its work, is strictly prohibited overloading, such as the discovery of abnormal sound or temperature is too high, should be immediately shut down to check and troubleshooting, equipment accidents should be protected from the scene, report equipment safety officer level by level. After the work is completed, in addition to careful maintenance according to the content of the equipment maintenance, but also must be all switches, handles put to the empty position, close the electric door and switch.
Injection molding (injection molding) is to make thermoplastic or thermosetting mold plastic first in the heated barrel uniform plasticization, and then by the plunger or mobile screw extrusion into the closed mold cavity molding a method. Injection molding is applicable to almost all thermoplastics. In recent years, injection molding has also been successfully used to mold certain thermoset plastics. Injection molding has a short molding cycle (a few seconds to a few minutes), the mass of the molded product can be from a few grams to tens of kilograms, and it can mold complex shapes, precise dimensions, and molded products with metallic or non-metallic inserts in a single run. Therefore, the method is highly adaptable and has high production efficiency. Injection molding injection machine is divided into two categories of plunger injection machine and screw injection machine, by the injection system, clamping system and mold three major components;
