Plastic Injection Mold hardness defects and preventive measures

  The use of molds is now very extensive. In order to improve the performance of mold manufacturing process, the heat treatment process is usually carried out for the molds. The common defects in heat treatment of molds are: quenching, deformation, poor hardness, electric machining cracking, grinding cracks, molds. Early destruction and so on. It can be seen that insufficient mold hardness is one of the common types of defects.

What are the reasons for the lack of mold defects and preventive measures?

There are five main aspects:

1. The quenching temperature is too low, mainly due to improper process setting temperature, temperature control system error, improper furnace installation or improper cooling tank method, etc. The process temperature should be corrected, the calibration temperature control system should be repaired, and the workpiece interval should be installed. Place it evenly and evenly into the trough. Do not stack or bundle into the trough to cool.

2, the quenching temperature is too high, which is caused by improper process setting temperature or temperature control system error, the process temperature should be corrected, and the photoelectric control system of the temperature control system should be overhauled.

3, over-tempering, this is caused by the tempering temperature setting is too high, the temperature control system fault error or the furnace temperature is too high, the furnace temperature should be corrected, the inspection and temperature control system should be repaired, not higher than the setting furnace temperature In.

4, improper cooling, the reason is that the pre-cooling time is too long, the cooling medium is not properly selected, the quenching medium temperature is getting higher and the cooling performance is lower, the mixing is poor or the trough temperature is too high, etc. Measures: tapping, entering the trough, etc.; grasping the quenching medium Cooling characteristics; oil temperature 60~80°C, water temperature below 30°C, when the quenching amount is large and the cooling medium is warmed up, cooling quenching medium should be added or other cooling tank should be used for cooling; strengthen the stirring of the coolant; at Ms+50°C Remove the threaded grinding insert.

5, decarburization, which is caused by residual decarburization layer of raw materials or quenching heating, preventive measures for controlled atmosphere heating, salt bath heating, vacuum furnace, box furnace with box protection or use of anti-oxidation coating; The amount is increased by 2~3mm.
