Description

Technical Field

[0001] The invention relates to the technical field of plastic panels, and in particular to a hot pressing mechanism and a hot pressing method for an acoustic plastic panel. Background Art

[0002] As people's lives get better and better, the changes in material life can no longer satisfy people, and spiritual needs have begun to occupy a part of people's lives. For example, watching movies, listening to music, listening to the radio, etc., all of these are inseparable from audio. As one of the necessary tools for auxiliary sound transmission, the demand for audio is also increasing. The control panel is indispensable for audio. People need to use the control panel to control, such as adjusting the volume, adjusting the sound quality, switching channels, etc., so the audio control panel has become a product urgently needed by society. With the rapid development of the plastics industry, the application of plastic panels is becoming more and more extensive, especially in the fields of electronic products, home appliances and automobiles. The appearance and functional requirements of these products are constantly improving, so higher requirements are put forward for the molding process of plastic panels. Traditional plastic hot pressing molding methods mostly rely on manual operation, which is inefficient and prone to quality fluctuations, and it is difficult to meet the high efficiency and high consistency requirements of modern production. However, innovation represents the need for progress in processing, among which the demand for progress in hot presses is the most important, because once the yield is too low in hot pressing processing, it is easy to increase the overall cost and more likely to cause problems such as delays in listing. These problems are not what manufacturers like.

[0003] Most of the existing hot pressing equipment is fixed and difficult to adapt to different working environments, which limits the flexibility and usage scenarios of the equipment. During the production process, operators need to frequently contact materials and lack reasonable storage design, which affects work efficiency. During the heating and pressurization process, the existing equipment may cause uneven heating of the plastic panel, resulting in unstable quality of the finished product. Many equipment lack effective buffer design when the lower mold contacts the upper mold, which can easily damage the mold and affect the service life of the equipment.

[0004] In order to overcome the above problems, a new type of hot pressing mechanism for acoustic plastic panels has been developed. The mechanism improves the mobility of the equipment through the combined design of the bottom plate and universal wheels; a storage slot is set up for the storage of items; and a pressurization and buffering mechanism combining a hydraulic plate and a return spring is introduced to improve the stability and safety of the pressurization process. At the same time, the heating plate inside the equipment uses rectangularly arranged heating rods to ensure uniform heating, thereby improving production efficiency and finished product quality.

[0005] To this end, we propose a hot pressing mechanism and a hot pressing method for an acoustic plastic panel. Summary of the invention
