Tie bar measurement system in die casting refers to a system used to detect and monitor the stress or deformation of the tie bar.

In the die-casting process, the pull rod is a long column that connects the fixed template and the movable template. Its main function is to transmit the locking force to keep the mold from being opened during the injection process. Therefore, the stress and deformation of the pull rod directly affect the stability of the mold and the quality of the product.

1. Tie bar measurement system in die casting method of pull rod

Mechanical measurement: Measuring the elongation of a tension rod by drilling holes on the rod and installing measuring devices such as measuring rods or strain gauges. For example, the stress of the tension rod can calculate by drilling a hole in the center of the rod. And inserting a measuring rod, and then reading the elongation of the measuring rod.

Electronic measurement: using strain gauges to directly measure the stress of the tension rod, this method can monitor the stress changes of the tension rod in real time, thereby more accurately controlling the locking force.

Ultrasonic measurement: In recent years, ultrasonic measurement technology has applied to stress monitoring of tension rods. By measuring the stress changes of tension rods in real time, it can imporve the accuracy and efficiency of measurement.

2. The significance of tie bar measurement system in die casting

Ensure mold stability: By measuring the stress of the pull rod, potential stress concentration issues that may occur during the use of the mold. It can detect in a timely manner. And measures can take to avoid mold damage.

Optimizing the production process: By monitoring the stress changes of the pull rod, the locking force can adjust to ensure the stability of each production process. Thereby improving product quality and production efficiency.

Fault warning: When the stress on the pull rod exceeds the safe range, the system can issue a warning to prompt the operator to perform maintenance or replace the pull rod, thereby reducing the risk of equipment failure.

3. Tie bar measurement system in die casting common specifications of pull rods

The diameter and spacing of the pull rod are important parameters that affect the performance of the die-casting machine. For example, some models of die-casting machines have a pull rod diameter of 125 millimeters and a spacing of 650 millimeters.
The spacing and diameter of the pull rods of different models of die-casting machines may vary. For example, some models have a pull rod spacing of 750 millimeters and a diameter of 150 millimeters.

4. Application of measurement system

Traditional method: By installing mechanical measuring devices such as measuring rods or strain gauges on the pull rod, it can directly measure the elongation or stress of the pull rod.

Modern technology: Advanced technologies such as wireless magnetic strain sensors use to achieve remote monitoring and data recording. Improving the convenience and accuracy of measurements.

The rod measurement system in the die-casting machine is an important tool to ensure the stability of the die-casting process and product quality. By monitoring and analyzing the stress of the pull rod in real-time, it can identify the potential problems. And resolve in a timely manner. Thereby optimizing production efficiency and extending equipment lifespan.
