Description

Technical Field

[0001] This utility model belongs to the field of mold processing technology, and in particular relates to a pressing device for quick mold changing. Background Technology

[0002] In modern manufacturing, pressing equipment is widely used in the production and processing of electronic products, automotive parts, and home appliances, where multiple components of a product are assembled or molded by applying pressure. With the diversification of market demand and the accelerated pace of product updates, manufacturing enterprises are facing a "multi-variety, small-batch" production model, which requires pressing equipment to be able to quickly change molds of different specifications to adapt to the production needs of different products.

[0003] Currently, traditional pressing devices typically use bolts to fix the mold when changing it. This requires using tools such as wrenches to loosen and tighten multiple fixing bolts one by one, and then relying on operators to manually remove the old mold and install the new mold. This traditional mold changing method is cumbersome and time-consuming, with the entire mold changing process usually taking 15-30 minutes or even longer, and requiring professional technicians or multiple people to complete.

[0004] However, the existing technology has the following technical problems: First, the excessively long mold change time seriously affects production efficiency. In the multi-variety, small-batch production mode, frequent mold change operations lead to low equipment utilization and increased production costs. Second, the bolt fixing method requires the use of wrenches and other tools to tighten each bolt individually, which is cumbersome, labor-intensive, and prone to causing unstable mold installation due to uneven tightening force. Third, the mold change process requires professional technicians or multiple people to operate, which requires high skill levels from the operators, resulting in high labor costs and safety hazards.

[0005] Therefore, it is necessary to develop a new type of rapid mold-changing pressing device to solve the technical problems of long mold-changing time, complex operation and low efficiency in the existing technology. Utility Model Content
