Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding machinery, and particularly relates to an automatic cutting device for a die mouth material blank of a blow molding machine. Background Art

[0002] In the field of injection molding machinery technology, blow molding machines play a vital role, especially in the production of various plastic products. However, a problem that has long plagued the industry is that during the continuous operation of the blow molding machine, the material cannot be automatically cut off after the die is discharged, resulting in unnecessary adhesion between the product and the die.

[0003] Traditional solutions rely on manual dragging to forcibly separate the blanks between the die and the product. However, this method has many disadvantages: first, long-term manual dragging operations will not only cause fatigue to the operator's hands, but may also cause burns due to direct contact with the high-temperature die, posing a threat to the operator's safety; second, manual operation is very unstable and prone to work errors, such as inaccurate cutting positions and uneven cutting forces. These problems not only affect product quality, but may also affect the overall efficiency of the production line; finally, relying on manual dragging will undoubtedly increase production costs, reduce production efficiency, and is not conducive to the long-term development of the enterprise.
