[0026] The demolding mechanism 4 includes a demolding rod 404 which is sleeved on the inside of the lower mold 1, and the top of the demolding rod 404 extends to the inside of the annular groove 101. A seal is provided at the connection between the lower mold 1 and the demolding rod 404. The demolding rod 404 is used to push the formed wood panel upward, thereby facilitating the demolding operation of the formed wood panel. It can be further explained that, through the vertical movement of the demolding rod 404, the wood panel bonded to the inner wall of the annular groove 101 after molding is moved upward together, thereby separating the wood panel from the inner wall of the annular groove 101. After the upper mold 2 moves to the initial position, the user can easily remove the formed wood panel. Compared with the traditional method of separating the annular groove 101 and the wood panel, the demolding efficiency of the wood panel is improved, and the degree of damage to the wood panel during demolding is also reduced, thereby reducing the cost of injection molding production of the wood panel.
[0027] See also Figure 3 and Figure 4The demoulding mechanism 4 also includes a moving block 401 sleeved inside the fixed seat 3, one end of the moving block 401 extends to the outside of the fixed seat 3, the inner wall of the moving block 401 is sleeved with a rotating column 402, the rotating column 402 is rotatably connected to the inner wall of the fixed seat 3 through a bearing, and the end of the upper mold 2 close to the fixed seat 3 is fixed with an extrusion block 201 by bolts, the extrusion block 201 is located below the moving block 401, the extrusion block 201 moves upward to squeeze the moving block 401 to move, and the movement of the moving block 401 can drive the rotating column 402 to rotate;
[0028] The outer wall of the rotating column 402 is provided with a spiral groove 4021, and the inner wall of the moving block 401 is provided with a ball 4011, and the ball 4011 is sleeved with the spiral groove 4021, and the ball 4011 moves upward and squeezes the spiral groove 4021 to rotate, and the spiral groove 4021 rotates and drives the rotating column 402 to rotate; a sliding block 4012 is fixed to one end of the moving block 401 by a bolt, and a limiting rod 4013 is sleeved inside the sliding block 4012, and the top and bottom ends of the limiting rod 4013 are respectively The sliding block 4012 is fixedly connected to the inner wall of the fixed seat 3 by bolts, and a spring 4014 is fixed to the top of the sliding block 4012. The spring 4014 is sleeved on the outside of the limiting rod 4013. The top of the spring 4014 is fixedly connected to the inner wall of the fixed seat 3. The setting of the sliding block 4012 and the spring 4014 is convenient for providing a reset force for the moving block 401 in the vertical direction. The limiting rod 4013 is used to limit the sliding block 4012 to prevent the sliding block 4012 from being displaced in the horizontal direction.
[0029] It can be further explained that the upper mold 2 moves upward and drives the extrusion block 201 to move at the same time. The extrusion block 201 moves and contacts the bottom end of the moving block 401, thereby driving the moving block 401 to move upward. The movement of the moving block 401 drives the ball 4011 and the sliding block 4012 to move. The spring 4014 is squeezed by force, and the ball 4011 moves and squeezes the inner wall of the spiral groove 4021, thereby driving the rotating column 402 to rotate.
[0030] See also Figure 4 and Figure 5The bottom end of the rotating column 402 passes through the interior of the lower mold 1, and the rotating column 402 is rotatably connected to the inner wall of the lower mold 1 through a bearing. A threaded rod 403 is welded to the bottom end of the rotating column 402, and the threaded rod 403 is connected to the inner wall of the demoulding rod 404 through a thread. The rotation of the rotating column 402 drives the threaded rod 403 to rotate, and the rotation of the threaded rod 403 can drive the demoulding rod 404 to move upward, thereby facilitating the demoulding operation of the formed wood veneer; the outer wall of the threaded rod 403 is connected to a support block 4031 through a bearing, and one side of the support block 4031 is fixedly connected to the inner wall of the lower mold 1 through a bolt. A moving groove 102 is opened on the inner wall of the lower mold 1, and the moving groove 102 matches the moving trajectory of the demoulding rod 404. The support block 4031 is used to support the threaded rod 403, so as to ensure the stability of the threaded rod 403 during the transmission of the rotational force, and the moving groove 102 is used to ensure the stability of the vertical movement of the demoulding rod 404.
[0031] It can be further explained that the rotation of the rotating column 402 drives the threaded rod 403 to rotate, and the rotation of the threaded rod 403 drives the demolding rod 404 to move upward, and the demolding rod 404 moves and the extruded wood panel moves upward. Since the wood panel fits against the inner wall of the annular groove 101 during molding, the demolding rod 404 moves upward and separates the wood panel from the annular groove 101, and then when the upper mold 2 moves to the initial position, the user can remove the molded wood panel.
[0032] See also Figure 1 and Figure 2 The top of the upper mold 2 is connected to an electric telescopic rod 202 through a coupling, and the outer wall of the electric telescopic rod 202 is fixed with a fixing frame 2021 by bolts. The fixing frame 2021 is fixedly connected to the top of the lower mold 1 by bolts. The movement of the output end of the electric telescopic rod 202 can drive the upper mold 2 to move in the vertical direction, thereby facilitating the demoulding and closing of the wood veneer. The fixing frame 2021 is used to support the electric telescopic rod 202.
[0033] It can be further explained that the output end of the electric telescopic rod 202 moves downward and drives the upper mold 2 to move downward. When the bottom end of the upper mold 2 fits with the top end of the lower mold 1, the user introduces the injection material into the annular groove 101. After the material is formed, the output end of the electric telescopic rod 202 moves upward and drives the upper mold 2 to reset. At this time, the formed wood veneer can be removed.
[0034] When in use, the user first controls the output end of the electric telescopic rod 202 to move downward, and the output end of the electric telescopic rod 202 moves downward and drives the upper mold 2 to move downward. When the bottom end of the upper mold 2 fits with the top end of the lower mold 1, the user then guides the injection molding material into the annular groove 101. After the material is formed, the output end of the electric telescopic rod 202 moves upward and drives the upper mold 2 to reset. At this time, the formed wood veneer can be removed;
[0035] Secondly, the upper mold 2 moves upward and drives the extrusion block 201 to move at the same time. The extrusion block 201 moves and contacts the bottom end of the moving block 401, thereby driving the moving block 401 to move upward. The movement of the moving block 401 drives the ball 4011 and the sliding block 4012 to move. The spring 4014 is squeezed by force. The ball 4011 moves and squeezes the inner wall of the spiral groove 4021, thereby driving the rotating column 402 to rotate. The rotation of the rotating column 402 drives the threaded rod 403 to rotate. The rotation of the threaded rod 403 drives the demoulding rod 404 to move upward. The demoulding rod 404 moves and squeezes the formed wooden panel upward. Since the wooden panel fits the inner wall of the annular groove 101 during molding, the demoulding rod 404 moves upward and separates the wooden panel from the annular groove 101. Then, when the upper mold 2 moves to the initial position, the user can remove the formed wooden panel.
[0036] Finally, through the vertical movement of the demolding rod 404, the wood panel bonded to the inner wall of the annular groove 101 after molding is moved upward together, thereby separating the wood panel from the inner wall of the annular groove 101. After the upper mold 2 moves to the initial position, the user can easily remove the molded wood panel. Compared with the traditional method of separating the annular groove 101 and the wood panel, the demolding efficiency of the wood panel is improved, and the degree of damage to the wood panel during demolding is also reduced, thereby reducing the cost of injection molding production of the wood panel.
