The manufacturing of injection molding mold can not be separated from the manufacturing of plastic mold. It can be said that the quality of plastic mold is directly related to the quality of injection molding products. So the machine design of injection molding has those four characteristics

1. Steel casting and mandrel capable of solving heat

The key design of any machine for grinding large parts is large steel castings and spindles capable of solving heat problems. In terms of machine forming, strength and heat reduction, steel castings are still stable materials. For the spindle, internal technology must be used for cooling to ensure that the spindle will not catch fire or have deviation due to high temperature

In order to make the surface of plastic injection mold reach the high quality standard, machines and tools must be used to greatly reduce the time of secondary electrical discharge processing and manual polishing

2. Thermal polishing technology

On the other hand, if the thermal smoothing technology is used, the same environmental change will cause the temperature of the column to change by 3 degrees, or 0.030 mm in the axial angle plane. However, the design of the machine can cover the thermal effect of the environment to prevent external gases from affecting the processing of parts. If the selected machine is heat constant, it will reduce the challenge of mixing condiments, thus reducing the need for manual polishing

3. Accuracy

If you want to finish polishing and blanking of large plastic molds on the same machine, precision is very important. It is very important to select a machining center that can accurately locate and precision similar to a small machine

The precision positioning of ± 0.000060 feet (± 0.0015 mm) and the precision of ± 0.000040 feet (± 0.001 mm) are required for the application of large injection mold machining centers. Another thing to mention is that the accuracy should also be guaranteed at 5 μ Within m

4. Reflective embodiment

In order to measure the machining accuracy, the feedback of the machine must be clearly known. one μ M's standard feedback is very common. When the feedback is 0.050 μ M, the polishing is almost defect free. Control and request feedback, subdivision screws can improve the surface finish

During the design of the industrial injection mold, both the designer and the later manufacturer should consider all kinds of problems as early as possible and take corresponding countermeasures
