Description
Technical Field
The utility model belongs to the technical field of film hot press forming, and particularly relates to a hot press forming device.
Background
The hot press molding of the polylactic acid film is to mold the polylactic acid film under high temperature and high pressure conditions. The film is softened by heat and then formed into a desired shape by pressure. Finally, the film cools and hardens and retains the molded shape. However, in the prior art, the polylactic acid film is stretched to be straight due to the inconvenience in hot press molding, which causes some disadvantages and challenges. The following are some drawbacks with respect to this problem:
fold formation: polylactic acid films are prone to wrinkling during hot pressing. When the film is not stretched effectively to keep the surface flat, the hot pressing pressure causes localized shrinkage and wrinkling. These wrinkles may reduce the appearance quality and mechanical properties of the final product.
Consistency problem: because the film cannot be fully stretched, the stress of the film in different areas is uneven and the temperature distribution is also uneven in the hot pressing process. This may lead to consistency problems in the formation, which may result in inconsistent thickness, strength and shape of the polylactic acid film in different parts, affecting the properties of the final product.
The molding efficiency is reduced: because of the generation of wrinkles, more trimming and correcting work is required in the hot press molding process to eliminate wrinkles. This will increase production time and cost and reduce production efficiency.
Intensity reduction: the formation of wrinkles damages the structure of the film, resulting in a decrease in strength. The physical and mechanical properties of the film will be affected and may not meet the desired application requirements.
In summary, when the polylactic acid film is hot-pressed and formed, the film is stretched and straightened due to inconvenience, which can lead to the generation of wrinkles and reduce the forming effect and consistency. Therefore, there is a need to develop a hot press molding apparatus for solving the above problems.
