Description

Technical Field

[0001] The utility model relates to the technical field of multilayer board forming devices, in particular to a high-strength cold-pressing template for multilayer boards. Background Art

[0002] In the manufacturing process of multi-layer boards, it is necessary to apply glue to multiple thin wood chips and stack them together as required to form a preliminary multi-layer board, and then put the preliminary multi-layer board into a cold press for cold pressing, leveling and forming. Referring to Chinese patent document CN218195791U, in the prior art, cold pressing is often performed directly using a cold press. After cold pressing, after a certain period of pressure maintenance, the pressing plate of the cold press is opened and the multi-layer board is taken out. This cold pressing method has three major problems: first, the pressing plate and base of the cold press are in direct contact with the multi-layer board and are easily damaged; second, after the multi-layer board is cold-pressed, it is difficult for the cold press to maintain pressure for a long time, so that the pressure maintenance time of the multi-layer board after cold pressing is not long enough and the quality is not good enough; third, because the cold press needs to set a time to maintain pressure on the multi-layer board, the cold pressing molding time is increased, and the cold pressing efficiency is low.

[0003] With the advancement of technology, technicians in this field have designed a cold pressing mold, which includes an upper mold and a lower mold. When cold pressing a multilayer board, the multilayer board is placed between the upper mold and the lower mold, and then the upper mold is pressed down by the pressing plate of the cold press to achieve cold pressing of the multilayer board and avoid direct contact between the pressing plate and the base of the cold press. However, this cold pressing method is still difficult to maintain pressure for a long time, and the pressure holding time of the multilayer board after cold pressing is not long enough, and the quality is not good enough; the cold press machine needs to set a time to maintain pressure on the multilayer board, thereby increasing the cold pressing time and the cold pressing efficiency is low; furthermore, the upper mold and the lower mold of the existing cold pressing mold are usually single-layer steel plates, which are not strong enough and are easy to bend and deform during cold pressing. At the same time, the upper mold and the lower mold of the existing cold pressing mold are not convenient for forklift transportation. Utility Model Content
