Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, and in particular to a mold clamping mechanism for a horizontal injection molding machine. Background Technology

[0002] The clamping mechanism of an injection molding machine is a component used to limit and fix the two molds together, preventing separation. An injection molding machine is a piece of equipment used for plastic processing, widely used in the manufacture of various plastic products. Injection molding machines play a crucial role in industrial production, typically used to produce a wide variety of plastic products. They are characterized by high efficiency, precision, and stability, and can meet the production needs of plastic products of different shapes, sizes, and materials.

[0003] However, most traditional injection molding machine clamping mechanisms use hydraulic systems for locking. Mold forming takes time, requiring the hydraulic system to maintain pressure for extended periods. This prolonged operation leads to severe wear and tear on the hydraulic system, necessitating frequent maintenance and replacement. This results in high maintenance costs and extended downtime for repairs, impacting the injection molding process. Furthermore, using pure hydraulic cylinders for locking also presents challenges due to high power requirements and energy consumption, contradicting current energy-saving and environmentally friendly production principles.
