Stability.In space utilization also more effectively, mold length and width shape is greatly reduced.The arrangement of ejection system uses and tooth
The mode that wheel shaft is inlayed reduces favorably with transmission system through mold height, the concentration of length, width and height size staggeredly, is equally reduced
In the processing of module, mold machining accuracy is more significantly improved.Due to using servo motor, gear transmission mode, connecting rod
Hexagon connects and U-shaped connection, makes the mechanism course of work steady, the product of production is particularly reliable and stable.The main reason is that knot
The compact module essence of structure is small, and machinability is higher, improves the precision of mold, also improves the precision of plastic therewith.Overall big
Reduction on small also saves mould material, alleviates mold weight, so as to decrease the manufacture cost of mold and time, also indirectly
Improve the production efficiency of product.
