Description

Technical Field

[0001] The utility model relates to the technical field of plastic box molding, in particular to a molding mechanism used for plastic box processing. Background Art

[0002] As a lightweight, durable and relatively low-cost packaging material, plastic boxes are widely used in many fields such as food, medicine, and electronic product packaging. These plastic boxes are usually produced through plastic molding technology, and the molding mechanism plays a vital role in this process. The molding mechanism is mainly responsible for the melting, injection, cooling of plastic raw materials and the demolding of molded products. In layman's terms, the main function of the molding mechanism is to transform plastic raw materials into the shape and size of the plastic box required by the user. The core part of the molding mechanism is the mold. The design and manufacture of the mold determines the precision, surface quality and production efficiency of the final product.

[0003] At present, most of the molding mechanisms for producing plastic boxes on the market use fixed molds, that is, each plastic box product needs a corresponding mold. When producing plastic boxes of different specifications or shapes, different molds need to be replaced. This design has several obvious shortcomings:

[0004] 1. The mold replacement process is inconvenient: mold replacement usually involves a complicated disassembly and assembly process, which not only consumes workers' labor time but also reduces production efficiency.

[0005] 2. Complex installation mechanism: Each mold often requires a specific connection structure and support equipment to be properly installed on the molding machine, which also limits the flexibility of production. Various installation mechanisms may require different operating skills, increasing the training cost of operators.

[0006] 3. Safety hazards: Since the temperature inside the mold is very high during the molding process, workers are very likely to get burned when changing the mold or taking out the product, affecting production safety.
