Technical Field
[0001] This utility model relates to the technical field of wood demolding equipment, specifically a demolding device for wood after it has been pressed and formed. Background Technology
[0002] Wood forming is the process of mixing wood chips with glue and then using high-pressure forming technology to process the wood into a specific shape or product. When manufacturing thin wood sheets, cylindrical wood is first produced by wood pressing and forming process, and then thin wood sheets are obtained by using a rotary slicing device along the rotating cylindrical wood. Finally, the thin wood sheets are rolled up to obtain a roll of thin wood sheets.
[0003] After the wood is pressed into a cylindrical shape, it is usually put into the drying equipment along with the mold. After the wood is shaped, it is demolded from the cylindrical mold. However, the demolding part is currently done manually, which is inefficient and labor-intensive. A demolding table is also used. The traditional demolding method is to fix the mold on the table and use a hydraulic cylinder to push the wood from bottom to top to demold it. This demolding method is easy to damage the wood and is not convenient to operate. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a demolding device for wood pressing and molding, including a frame, a central hydraulic cylinder 1, side hydraulic cylinders 2, a lifting plate 3, a chain 4, a pressure plate 5, and a sliding plate 6; the frame includes columns 7 and a top plate 8, with several columns 7 arranged on the lower surface of the top plate 8, a central hydraulic cylinder 1 arranged in the middle of the upper surface of the top plate 8, and side hydraulic cylinders 2 symmetrically arranged on both sides of the central hydraulic cylinder 1 on the upper surface of the top plate 8. The piston rods of the central hydraulic cylinder 1 and the side hydraulic cylinders 2 pass through the top plate 8. The top plate 8 has three through holes, and guide sleeves 14 are arranged below each through hole. The piston rods of the central hydraulic cylinder 1 and the two side hydraulic cylinders 2 are respectively guided and cooperated with the corresponding guide sleeves 14 to ensure the stability of the piston rods of the central hydraulic cylinder 1 and the side hydraulic cylinders 2. The piston rods of the side hydraulic cylinders 2 are connected to the lifting plate 3, and the upper surface of the lifting plate 3 is provided with two annular positioning grooves 15. The positioning groove 15 is inserted and fastened with bolts to ensure the connection stability between the piston rod of the side hydraulic cylinder 2 and the lifting plate 3. The piston rod of the middle hydraulic cylinder 1 passes through the lifting plate 3 and is provided with a pressure plate 5 at the bottom. A guide hole 16 is opened in the middle of the lifting plate 3. The piston rod of the middle hydraulic cylinder 1 is guided and cooperated with the guide hole 16 to ensure the stability of the piston rod of the middle hydraulic cylinder 1. A connecting sleeve 17 is provided on the upper surface of the pressure plate 5. The bottom of the piston rod of the middle hydraulic cylinder 1 is connected to the pressure plate 5 through the connecting sleeve 17 and bolts to enable the piston rod of the middle hydraulic cylinder 1 to pass smoothly through the guide hole 16 of the lifting plate 3. Several chains 4 are provided on the outer edge of the lifting plate 3 through the fixing buckle 9. Each chain 4 is provided with a hook 10 at the bottom. The hook 10 cooperates with the lifting lug of the forming cylinder 13 to lift the forming cylinder 13 and separate it from the wood. The two sides of the slide plate 6 are slidably cooperated with the track 12 through the roller 11. The slide plate 6 is slidably set under the pressure plate 5.
[0020] Working method and operating principle: After the wood is formed in the forming cylinder 13 by the forming equipment, it is dried and shaped at high temperature. Then the forming cylinder 13 is moved onto the slide plate 6 and then moved under the pressure plate 5 via the slide plate 6. At this point, the lifting plate 3 is lowered by the two side hydraulic cylinders 2. After the hook 10 at the bottom of the chain 4 is connected to the lifting lug of the forming cylinder 13 by a person, the middle hydraulic cylinder 1 lowers the pressure plate 5 and puts the pressure plate 5 into the forming cylinder 13 and presses it on the wood. Then the piston rods of the two side hydraulic cylinders 2 retract and drive the lifting plate 3 to rise. The lifting plate 3 then drives the forming cylinder 13 to rise through the chain 4 until the formed wood is completely separated from the forming cylinder 13. Then the middle hydraulic cylinder 1 drives the pressure plate 5 to rise and leave the top of the wood. After pushing the slide plate 6 away, the forming wood is unloaded from the slide plate 6 by the crane, electric hoist and clamp. Finally, the slide plate 6 is moved to the bottom of the pressure plate 5. The forming cylinder 13 is placed on the slide plate 6 by the two side hydraulic cylinders 2 and the hook 10 is separated from the forming cylinder 13 to complete one demolding. This utility model has a reasonable structure. The lifting plate 3 is driven to rise and fall by the side hydraulic cylinder 2. Then, the chain 4 and hook 10 cooperate with the lifting lug of the forming cylinder 13 to lift the forming cylinder 13. At the same time, the pressure plate 5 at the bottom of the piston rod of the middle hydraulic cylinder 1 limits the wood to separate the wood from the forming cylinder 13, which greatly improves the unloading efficiency, reduces the unloading difficulty, and saves labor costs. Furthermore, the sliding plate 6 facilitates the recycling of the forming cylinder 13.
