I. Technical Background
In the process of mold manufacturing and maintenance, mold separation is an indispensable step. Molds must be accurately separated into upper and lower parts before mold fitting, maintenance, or cleaning. The performance of a mold splitter directly determines the precision, efficiency, and stability during the operation process.
Currently, the mainstream mold splitters on the market are still mainly hydraulically controlled (or servo-hydraulically controlled). However, hydraulic systems have shortcomings such as slow response speed, susceptibility to electromagnetic interference, and insufficient dynamic balance, which make them difficult to meet the requirements of high-precision molds. Against this background, all-electric mold splitters driven by servo motors have emerged. With their high-speed response and high-precision compensation, they have gradually become the development trend of the industry.
II. Advantages of All-Electric Control Technology
Dynamic Synchronous Position Adaptive Adjustment
The dynamic balance of the template is achieved by real-time detection of position differences via magnetostrictive displacement sensors on both sides, with data fed back to the PLC. This parallelism refers to the dynamic parallelism during equipment operation, rather than the static parallelism when the equipment is stationary.
The internal algorithm of the PLC dynamically adjusts the electronic coupling gear ratio of the dual motors to realize real-time automatic balance between the left and right sides of the template.
The adoption of closed-loop control + servo motor position compensation effectively avoids precision degradation caused by mechanical wear.
The movement of the upper plate is transmitted through P-class ball screws with zero clearance, maintaining high precision over the long term.
High-Speed Response and Precise Control
*The power source adopts direct drive by dual servo motors, combined with PROFINET IO IRT bus communication.
*It features strong anti-interference capability and efficient, stable data transmission, ensuring faster response speed and higher control precision.
