I. Definition and Purpose
• Definition: A proportional valve is a type of valve that can continuously and proportionally control fluid pressure, flow rate, or direction based on an input signal (such as current or voltage). In the context of a 2700T injection molding machine, the mold clamping proportional valve specifically refers to the proportional valve used to control the pressure and flow rate during the mold clamping process.
• Purpose: This proportional valve plays a crucial role in the mold clamping process of injection molding machines, enabling precise control of the mold clamping force to ensure that the mold remains tightly closed during the injection molding process, thereby producing high-quality products.
II. Working Principle
• Input Signal: The proportional valve receives an input signal from the injection molding machine's control system, which is typically a current or voltage value indicating the required mold clamping pressure and flow rate.
• Electromagnet Control: The proportional valve contains an electromagnet that generates a corresponding magnetic force based on the magnitude of the input signal, thereby controlling the movement of the valve spool.
• Fluid Control: The movement of the valve spool alters the area of the fluid passage, thereby controlling the fluid pressure and flow rate through the proportional valve. This allows the injection molding machine to adjust the mold clamping force according to actual needs.
III. Characteristics and Advantages
• High Precision: The proportional valve can precisely control fluid pressure and flow rate, ensuring stability and accuracy in the mold clamping process of injection molding machines.
• Fast Response Time: The proportional valve has a very fast response time, enabling it to adjust the mold clamping force within a short period of time to meet the high-efficiency demands of injection molding production.
• Strong Adaptability: The proportional valve can be adjusted according to different injection molding materials and mold structures to adapt to various production conditions.
• Made in China: This proportional valve is manufactured in China, reflecting China's manufacturing capabilities and technical expertise in the field of injection molding machines and their accessories.
IV. Application Example
In a 2700T injection molding machine, the mold clamping proportional valve is typically installed at the inlet and outlet of the mold clamping cylinder to control the mold clamping and opening processes. By precisely controlling the mold clamping force, it ensures that the mold remains tightly closed during the injection molding process, preventing melt leakage and mold damage. Additionally, the fast response capability of the proportional valve meets the high-efficiency demands of injection molding production, improving production efficiency and product quality.
In summary, "Proportional valve for mold clamping of 2700T injection molding machine, made in China" is a high-precision, fast-response, and adaptable injection molding machine accessory manufactured in China and widely used in various injection molding production processes.
