What are the basics of plastic molds and injection molds?

The innovation of plastic mold processing technology, the wide application of various new mold materials, the standardization and specialization of mold parts, force us to speed up the design speed to adapt to the development of the mold.

The improvement of speed requires the design segment to be completed in about 3 days; the improvement of plastic mold precision requires the processing method of each part to be clearly considered in the design process, and the processing method with high precision and low processing cost should be adopted as much as possible. The improvement of precision and speed is consistent. The improvement of speed necessarily requires the improvement of precision; the improvement of precision necessarily leads to the improvement of speed.

1. Structural system: template, support column, limit column, etc.

2. Forming system: female mold core, male mold core, inserts, etc.

3. Pouring system: main flow channel, branch flow channel, gate, cold slag well, etc.

4. Guiding and positioning system: guide pillar, guide bush, zero degree precision positioning, taper precision positioning, etc.

5. Ejector system: ejector pin, cylinder pin, push plate, air ejector, thread ejector, compound ejector, etc.

6. Temperature control system: water channel, water tower, nozzle, etc.

7. Exhaust system: parting surface exhaust, block exhaust, ejector pin exhaust, steel exhaust, etc.

8. Core extraction system: front mold core extraction, rear core extraction, inclined top, etc.

9. Standard parts system: screw, sleeve, waterproof ring, etc.

10. Safety reset system: micro switch, forced reset, etc.
