Generally, in this type of situation, it should be blocked by the nozzle head or the body. At this time, observe whether there is no bright spot at the top of the cutting head. If it is all gray in section, it means that the nozzle is blocked. The solution is as follows: 1. Adjust the temperature of the nozzle to adjust it; 2. Reduce the time from the nozzle to 0.1 to 0.2 seconds; 3. Set the cooling water of the mold to a small point.
2, [Easy to crack when casting thin-walled products]
Can be analyzed from the following points: 1, the material may have problems, the use of die casting materials, try to control the proportion of waste not to exceed 30%; 2, the mold is not good, one is the topping force imbalance; the second is the cooling water The unreasonable opening caused the mold temperature to be unbalanced, and the filling flow alone was unreasonable. 3, the process parameters are not properly selected, the process parameters are mainly in the time of the magic time and the ejection delay time, the mold retention time should not be long, the thickness of each mm wall is about 3s; the ejection delay can not be long, generally 0.5-2s.
3, [hammer stuck]
In order to avoid the hammer head stuck, you can start from two aspects: 1. In the production, the temperature is often measured to avoid the hammer head and the cylinder temperature being too high, causing the hammer head to be stuck; 2. The use of materials should select high-quality alloy. The material should avoid the infiltration of impurities. When placing the return material, be careful not to let the impurities mix in, so as to avoid the impurities sticking to the hammer head and causing the hammer head to be stuck.
How to do the die-casting mold adhesive? First check whether the mold temperature is normal, reduce the casting temperature of the alloy liquid and the mold temperature; 2. Check whether the ratio of the mold release agent is abnormal, try to replace the mold release agent, and debug the surface of the spray position for polishing. Carefully polish the nitrided mold to prevent the nitride layer from damaging the surface and form a more viscous bond. 4. Improve the design of the casting system to prevent the alloy liquid from continuously scouring the cavity wall or core; Modify the mold cooling system; 6, adjust the die casting process parameters, properly reduce the injection speed, and shorten the second speed stroke.
5. [The feedback material is harder when the ADC14 material is die-casting, and the tool is easy to wear]
To solve this problem, we can look at the following points: 1. The most important thing is that the ingredients are not allowed to have impurities, that is to say, hard spots, it is best to use all new raw materials, not to be regenerated. The quality of the material, especially the S1 element, is good; 2. The gemstone blade specially produced for these relatively hard alloys should have a service life of about 7 days.
