[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1 - Figure 4 As shown, in this embodiment, the lifting mechanism 5 is used to facilitate the rapid demoulding and material removal operation of the environmentally friendly pulp molded product after being pressed and formed in the mold groove 4 of the lower mold 3, so as to achieve the purpose of improving production efficiency, and the specific use principle of the lifting mechanism 5 in conjunction with the upper and lower molds 3 is as follows:

[0021] After the environmentally friendly pulp molded product is pressed and formed by the upper mold 2 in the mold groove 4 on the top surface of the lower mold 3, the cylinder 17 on the left wall of the fixed plate 8 installed in the inner cavity 7 opened in the lower mold 3 will be started, and the output end of the cylinder 17 will push the movable plate 18 to the right, and the T-shaped slider 19 installed on the bottom surface of the movable plate 18 will slide in the T-shaped slide groove 16 opened on the top surface of the track plate 15 installed on the inner bottom surface of the inner cavity 7. In the process of the movable plate 18 moving to the right direction on the top surface of the track plate 15, the semicircular shaped slider installed on the top surface will be pushed to the movable plate 18. The extrusion plate 20 is pressed against the pressure plate 14 which is in an inverted semicircular shape installed at the center of the bottom surface of the lifting plate 11. After receiving the extrusion force from the extrusion plate 20, the pressure plate 14 will push the lifting plate 11 upward. The lifting plate 11 will move upward along the symmetrical fixing rods 9 installed in the inner cavity 7 through the connecting holes 12 opened on the top surface, and drive the return spring 10 which is set on the outside of the fixing rod 9 to stretch upward. At the same time, the four corner ends of the top surface of the lifting plate 11 are installed and inserted into the bottom surface of the mold groove 4. The lifting rod 13 in the corresponding guide hole 6 will move upward through the guide hole 6 to the inside of the mold groove 4, and in the process, the environmentally friendly pulp molded product pressed and formed in the mold groove 4 will be ejected from the inside of the mold groove 4. Finally, the staff can directly take the product down. After the extrusion plate 20 moves to the right side of the pressure plate 14, the pressure plate 14 will lose the extrusion force of the extrusion plate 20, the reset spring 10 will perform a recovery retraction operation, and drive the lifting plate 11 to move downward, and the lifting plate 11 will drive the top surface of the lifting rod 13 to re-enter the guide hole 6, and in the next When the product in the mold groove 4 is demoulded for the first time, the output end of the cylinder 17 can drive the movable plate 18 to move to the left through a pulling operation. Similarly, the pressure plate 14 is squeezed by the extrusion plate 20, and the pressure plate 14 pushes the lifting plate 11 to move upward so that the lifting rod 13 on the top surface of the lifting plate 11 can complete the lifting and demoulding operation of the product in the mold groove 4, thereby achieving the purpose of quickly demoulding the environmentally friendly pulp molded product after compression molding in the mold groove 4, avoiding manual material removal, and the product can be quickly removed after demoulding, thereby improving work efficiency.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, various improvements may be made to the present invention and its components may be replaced by equivalents, or some of its technical features may be replaced by equivalents without departing from the scope of the present invention. All that is within the spirit and principles of the present invention should be included in the protection scope of the present invention.
