Description

Technical Field

[0001] The invention relates to the field of heating and demoulding based on PCM prepreg plies, and in particular to a transfer tooling based on heating and demoulding based on PCM prepreg plies. Background Art

[0002] Prepreg is a composite of resin matrix and reinforcement made by impregnating continuous fibers or fabrics with a resin matrix under strictly controlled conditions.

[0003] When traditional PCM prepreg layers are heated and demoulded, the temperature of the heating tooling increases, and the viscosity of the prepreg increases. After the layering operation is completed, the heating tooling needs to be placed in the cooling area to cool before it can be peeled off. The work efficiency is extremely low. When the tooling is peeled off, the product is not easy to separate. After separation, a certain amount of adhesive remains on the surface of the tooling, which is difficult to clean. Some products are easily damaged at the corners when they are taken out, affecting the appearance quality of the equipment and even the normal use function of the product. Summary of the invention

After the plying operation is completed, the heating tool needs to be placed in a cooling area for cooling before it can be peeled off, and the work efficiency is extremely low. When the tool is peeled off, the product is not easy to separate, and a certain amount of adhesive remains on the surface of the tool after separation, which is not easy to clean. Some products are easily damaged at the edges and corners when they are taken out, affecting the appearance quality of the equipment and even affecting the normal use function of the product.
