Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing forming equipment, in particular to a hot pressing forming device for a palm fiberboard. Background Art

[0002] Mountain palm fiberboard is a board made of mountain palm fiber as the main raw material. Mountain palm fiber has the characteristics of long fiber, high strength, good toughness, corrosion resistance, and insect resistance. Mountain palm fiberboard is widely used in home, transportation, packaging and other fields; At present, in the processing of mountain palm fiberboard, hot pressing molding equipment is needed for production.

[0003] The utility model patent with the authorization announcement number CN215943271U discloses a hot pressing mold for medium density fiberboard, which includes a workbench, a lower mold and an upper mold, the lower mold is located between the upper mold and the workbench, the top of the workbench is fixedly installed with a support foot, the support foot is fixedly connected to the lower mold, an ejection mechanism is installed in the middle of the bottom of the workbench, the top of the ejection mechanism is fixedly installed with a bottom plate located inside the lower mold, the bottom of the workbench is installed with a limited mechanism, and the bottom of the workbench is fixedly installed with a support seat. Through the cooperation between the bottom plate and the ejector, when the bottom plate moves downward, the ejector moves downward, and the reset spring is compressed at the same time, and the ejector is fixed through the cooperation between the column and the disc and the mounting sleeve and the fastening bolt. When the formed fiberboard needs to be taken out, the fastening bolt is loosened at this time, so that the reset action of the reset spring makes the ejector move upward, so that the ejector drives the bottom plate to move upward and ejects the fiberboard inside the lower mold, thereby replacing manual operation to reduce safety hazards.

[0004] Although the hot-pressing forming mold for medium-density fiberboard is convenient for ejecting the formed fiberboard, the device still has the following problems when in use. Specifically, the device relies on the elastic force of a return spring to eject the fiberboard, but the spring has certain limitations when in use. On the one hand, if the elastic force of the spring is too large, the fiberboard may be ejected out of the mold too violently, thereby falling and possibly being damaged; on the other hand, if the elastic force is too small, it is difficult to ensure the smooth ejection of fiberboards of different thicknesses; in addition, with the long-term use of the spring, its elastic effect will gradually weaken, which makes the ejection effect of the equipment become worse and worse over time. In view of this, we propose a hot-pressing forming device for mountain palm fiberboard. Utility Model Content

The connecting rods 23 pass through the horizontal plate 111 and are slidably connected to the horizontal plate 111. A spring 24 for pressing against the horizontal plate 111 is sleeved on the connecting rod 23; a vertical plate 25 is also installed at the center of the top plate 22, and the vertical plate 25 passes through the horizontal plate 111 and is slidably connected to the horizontal plate 111. A rectangular groove 251 is opened at the bottom end of the vertical plate 25, and a cam 27 is rotatably installed in the rectangular groove 251. A transmission shaft 26 is coaxially keyed between the two cams 27, and a motor 21 for driving the transmission shaft 26 to rotate is also installed under the base 10.

[0028] In this embodiment, the top plate 22 is fixedly connected to the vertical plate 25 by bolts, and both the top plate 22 and the vertical plate 25 are made of stainless steel. This connection method is simple and firm, and is easy to disassemble and assemble. Stainless steel has the characteristics of corrosion resistance and high temperature resistance, and is suitable for the working environment of hot pressing molding equipment.

[0029] In this embodiment, the bottom end of the connecting rod 23 is coaxially keyed to a limiting block, and the diameter of the limiting block is larger than the diameter of the connecting rod 23. The setting of the limiting block can prevent the connecting rod 23 from detaching from the horizontal plate 111, thereby ensuring the stability of the top plate 22.
