Die casting machine tie bars break because excessive mechnical stress, metarial and design issues, production speed and mold design and so on.

The reasons for the fracture of the connecting rod (Tie Bar) of the die casting machine can be analyzed from multiple aspects:

1. Die casting machine Tie Bars Break: Excessive mechanical stress

During the die casting process, the connecting rod needs to withstand huge mechanical stress. For example, the clamping force of the cold chamber die casting machine can reach thousands of tons. It requires the connecting rod to have sufficient strength and rigidity to withstand such pressure. If the material or design of the connecting rod fails to meet these requirements, it may cause it to break.

2. Die casting machine Tie Bars Break: Material and design issues

The material and design of the connecting rod are important factors affecting its life. If the material strength is insufficient or the design is unreasonable. Such as the bolts are too tight or too loose. It may cause the connecting rod to fail under high pressure or vibration conditions. In addition, the surface treatment and manufacturing quality of the connecting rod may also affect its performance.

3. Die casting machine Tie Bars Break: Production speed and mold design

High-speed production will cause the connecting rod to bear greater mechanical loads. If the mold design is unreasonable. Such as the cavity wall is too thin or the material has good fluidity but a large forming area. The stress on the connecting rod may increase. In addition, the symmetry of the mold and the design of the fixing points will also affect the force distribution of the connecting rod.

4. Insufficient lubrication

During the die casting process, proper lubrication can reduce mechanical stress and wear. If the lubrication is insufficient, it may cause the connecting rod to be damaged due to friction and high temperature.

5. Aging and maintenance issues

Long-term use of connecting rods can lead to material fatigue and aging, which reduces their strength and toughness. Improper maintenance, such as failure to replace worn parts in a timely manner or failure to conduct regular inspections, can also accelerate the breakage of connecting rods.

6. Other external factors

Mismatch or failure of other parts of the die casting machine (such as molds, push rods, etc.) may also indirectly affect the stress state of the connecting rod. For example, a slight deviation of the mold may cause the connecting rod to bear uneven stress.

The reasons for the fracture of the connecting rod of the die casting machine are usually multifaceted. Including excessive mechanical stress, material and design problems, unreasonable production speed. And also mold design, insufficient lubrication, aging and improper maintenance, and other external factors. In order to reduce the risk of connecting rod fracture, it is necessary to comprehensively consider multiple aspects such as material selection, design optimization, production control and maintenance management.
