Description

Technical Field

[0001] This utility model relates to the field of blow molding machine technology, and specifically to a quick mold changing device for blow molding machines. Background Technology

[0002] In the blow molding process, mold changing is a frequent and crucial task. Traditional mold changing methods mostly involve hoisting and transporting the entire mold set at once. This method has several drawbacks. First, the heavy weight of the mold makes transporting and installation difficult, requiring significant manpower and time, resulting in low efficiency. Second, changing the mold while it's closed in the blow molding machine presents limited space and operational inconvenience, easily leading to improper mold installation and affecting the quality of subsequent products. Furthermore, complete mold changing places high demands on hoisting equipment, increasing production costs and equipment investment.

[0003] Therefore, it is of great significance to provide a quick mold changing device for blow molding machines to solve the problems existing in the current technology. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a quick mold changing device for a blow molding machine to solve the problem of limited space and inconvenient operation when changing molds in the mold-closed state of the blow molding machine.
