The injection mold can be put into normal production after successful design, processing and debugging. The correct use and maintenance is an important factor to ensure the continuous production of high quality plastic products and extend the service life of mold injection. The correct use and careful maintenance of mold injection, to maintain the normal production of enterprises, improve enterprise efficiency, has a very important significance.
Mold injection and molding machine with the use of both indispensable. The operation of the injection mold is actually completed by operating the injection molding machine, should pay attention to the following aspects.
I. adjustment of mold opening and closing speed and low pressure protection
In the process of mold opening or closing, the change of speed is based on "slow speed - fast - slow speed". In the process of mold closing, to ensure that the template can move without the principle of crawling behavior, the system pressure to make the moving template advance before the contact of the mold injection is set to the minimum.
Second, mold closing force adjustment
In normal production, according to the specific situation in the actual injection from low to high gradually adjust, in order to ensure that the plastic products mannuma spirit requirements, try to use low closing force.
Third, the introduction of institutional adjustment
Plastic products in the eyes of the introduction of plastic products affect the quality of plastic products, must be carefully adjusted, do the following several aspects.
1. Push the schedule
Should ensure that the plastic products completely out.
2. Number of launches
Generally simple, small depth of plastic products can be set out once, and complex, depth of plastic products set two, or even three times.
3. Push speed
Speed and plastic raw materials, plastic products structure and mold injection temperature, the speed is too high easy to break plastic products, from low to high adjustment, in order not to damage the plastic products for the principle.
Iv. Mould injection temperature control
Mould injection temperature is closely related to the material formed and should be strictly controlled. On the one hand, the accuracy of the temperature control meter needs to be calibrated frequently; on the other hand, it is necessary to constantly observe whether the working status of the instrument is normal and observe whether the heating and cooling pipes are unblocked and in good condition to ensure the control accuracy of the mold temperature.
Take out plastic parts
Molding parts out, according to the size of the products, there are automatic fall, manual removal and removal of the manipulator 3 methods. However, regardless of the mode of operation and the method of taking parts, should ensure that in each work cycle, must be the parts and pouring system material completely clean out. In particular, the injection machine is in a fully automatic working state, it is necessary to set "take out parts" as the necessary condition to control the injection machine to enter the next working cycle. Otherwise, once there are parts left in the mold injection, injection machine and the next cycle of closing action, in most cases back to damage the mold injection, or even the mold injection serious deformation and scrap, must be given full attention.
