Description

Technical Field

[0001] This utility model relates to the field of plastic hot pressing molding technology, and in particular to plastic hot pressing molding equipment with cooling function. Background Technology

[0002] Thermoforming equipment can be used to manufacture various plastic packaging containers, such as plastic boxes and plastic trays. After thermoforming, the cooling function is used to quickly set the product shape. For example, in the food packaging field, plastic trays for holding pastries, chocolates and other foods are produced. Rapid cooling after thermoforming can ensure the shape accuracy of the tray, allowing it to better support and protect the food. For some products with high requirements for packaging appearance, such as electronic product packaging and cosmetic packaging, rapid cooling reduces surface defects, making the packaging shell smoother and flatter, and improving the overall grade of the product.

[0003] In existing technologies, some mold plates are typically secured by loosening bolts, nuts, or other clamping devices using tools such as wrenches. When loosening these devices, care should be taken to follow a specific sequence, usually loosening them symmetrically, to avoid uneven stress on the mold plate.

[0004] However, in practical use, the inability to change the mold plate means that the equipment can only be used to produce plastic products of specific shapes and specifications. For example, in the packaging industry, if the mold plate cannot be changed, only one size and shape of plastic packaging containers can be produced, such as only one fixed size plastic box. It is impossible to flexibly switch production tasks according to market demand (such as customers requiring different sizes and shapes of packaging boxes to package different products). In response to the above problems, a plastic thermoforming equipment with cooling function is proposed. Utility Model Content
