What is the material of the die casting mold

date:2022-07-17 17:51:42 visits:101 source:admin

The materials of die-casting molds are mainly steel molds and aluminum molds. There are steel molds and copper molds for injection molds. If the products produced are rigid products, because most of these products require high precision and strict requirements for thermal conductivity, otherwise the value of the product will be lost. Like aluminum molds and copper molds, there are no restrictions in this regard, such as PE, Products such as PVC often use copper molds.

Die-casting die is a method of casting liquid die forging, a process completed on a dedicated die-casting die forging machine. Its basic process is: the molten metal is first cast at low speed or high speed and filled into the cavity of the mold, the mold has a movable cavity surface, and it is pressurized and forged with the cooling process of Energy Storage Device Parts the molten metal, which not only eliminates the shrinkage of the blank. Loose defects also make the internal structure of the blank reach the broken grains in the forged state. The comprehensive mechanical properties of the blank are significantly improved.

Precautions for maintenance and repair of zinc alloy die-casting molds:

(1) For vulnerable parts, such as ejector pins, cores, etc., carefully check for bending, cracks, etc. If there are, replace them in time. In many cases, when the mold is reproduced, the core is broken without completing many molds. , Most of the reasons are not carefully checked and problems are not discovered in advance, resulting in a great waste of manpower and time.

(2) The polishing zinc alloy die-casting mold needs to be supplemented. Where there is sticky aluminum and carbon deposits, it is polished to minimize the wear and tear on the mold caused by polishing.

(3) Lubrication and anti-rust treatment should be performed on all moving parts of the mold, joint parts, screws, etc.

(4) Die-casting mold management personnel shall supervise the maintenance status at any time, pay attention to other management details, and make maintenance and repair records for inquiries.

(5) The storage of molds should be consistent with accounts, drawings, files, etc. The molds cannot be disassembled and stored to avoid the loss of parts. Zinc alloy die-casting molds that have not been used for a long time should be regularly treated for rust prevention. The new mold should be treated with stress relief as much as possible within the specified period to prolong its service life.

In the process of mold maintenance and repair, some of them are quite simple and understandable, but it is difficult to actually do it. We need to implement it with due diligence and do the work well.
