Precision mold processing technology for high-speed precision stamping mold manufacturing


   In recent years, the national precision instrument industry has developed rapidly, and precision mold processing is used in the fields of automobiles, electronic products, machinery, molds and so on. Among them, the development of medical machinery, automobiles, aerospace and other fields is relatively strong. However, the processing technology of these precision molds is relatively difficult, the precision process requirements are high, the added value increases with the increase of the processing chain, and the profitability is high. Multi-station progressive die production requirements have some characteristics: difficult coordination, high labor-consuming, long cycle, long life, high dimensional stability, high wear resistance, high strength, high hardness, etc. three key parts




Faced with these problems, we should introduce some high-precision cutting machine tools, change the thickness, eliminate adverse effects, compare the workpiece, standard process, double wire process, etc., reduce the roughness of some process surfaces, and achieve high precision and high quality. , High-efficiency precision mold processing benefits.






There are usually three types of injection mold quick clamping systems: electromagnetic clamping system, hydraulic clamping system and mechanical manual clamping system. The characteristics of each quick clamping system determine their application range.




1. Electromagnetic clamping system




1. The electromagnetic clamping system is suitable for injection molding machines with a clamping force of 300 to 350 tons. Below this level, there will be insufficient mold surface area to ensure sufficient clamping force.


2. The main advantage of the electromagnetic system is that there is no need to modify the mold, no special backplane, and the system can accept backplanes of any shape.


3. The electromagnetic clamping system can be quickly installed and operated quickly, almost free of maintenance, and no need to replace the transfer parts.


4. Electromagnetic clamping system is the lowest cost choice commonly used in fast clamping applications.








2. Mechanical manual clamping system




Mechanical manual clamping system, the mold is fixed in position by manual bayonet, this is only suitable for 250 tons injection molding machine. This type of low-cost system is relatively easy to install. Almost all injection molding machines can be assembled.




3. Hydraulic clamping system




The hydraulic system is suitable for injection molding machines of any size. Single-acting or double-acting hydraulic clamps conform to EUROMAP standards and can be used for automatic clamping of existing and new machine molds. The clamp acts on a steel mold back plate, and the mold is fixed on the steel back plate with bolts.




Compared with the mechanical manual clamping system, the hydraulic clamping system requires more changes to the mold. In addition, the size of the backplane is very important for effective locking. The backing plate must be permanently fixed with each mold, which greatly increases the total cost of this type of clamping system.




The hydraulic system installed on the injection molding machine may not be sufficient to support the mold clamping system, and often requires frequent upgrades before installation.




Nowadays, more and more injection mold manufacturers will try it out before installing the clamping system. Which system is actually installed is usually left to their customers to make a choice to suit the particular application involved. The installation cost of the hydraulic clamping system is low and very simple, but the mold system needs to be updated and upgraded, and the new universal size panel may be extremely expensive.




For injection molding machines exceeding 250 tons, manual mechanical systems cannot withstand mold opening forces exceeding 25 tons (assuming 10% of clamping force). For this type of application, the best choice is between a hydraulic clamping system and an electromagnetic clamping system.
