[0026] In one embodiment, Figure 1 and Figure 2As shown, the demoulding lifting mechanism 6 includes a demoulding module 61 slidably connected to the inner wall of the concave mold groove 5, and a pair of lifting connecting rod mechanisms for demoulding are arranged at the bottom end of the demoulding module 61. The lifting connecting rod mechanism includes a first connecting block 621 fixedly connected to one side of the lower end of the demoulding module 61, and a second connecting block 622 is arranged on the side of the lower end of the demoulding module 61 away from the first connecting block 621. The surface of the first connecting block 621 is rotatably connected to the first connecting rod 623, and the surface of the second connecting block 622 is rotatably connected to the second connecting rod 624. The center position of the first connecting rod 623 and the second connecting rod 624 is rotatably connected, the other end of the first connecting rod 623 is rotatably connected to the third connecting rod 625, the other end of the second connecting rod 624 is provided with a fourth connecting rod 626, the center position of the third connecting rod 625 and the fourth connecting rod 626 is rotatably connected, the other end of the third connecting rod 625 is rotatably connected to the third connecting block 627, the other end of the fourth connecting rod 626 is rotatably connected to the fourth connecting block 628, and the bottom ends of the third connecting block 627 and the fourth connecting block 628 are fixed to the molding Inside block 4, a telescopic mechanism is arranged between the third connecting blocks 627, and the telescopic mechanism includes a first cross bar 631 fixed between the third connecting blocks 627, and the position between the first cross bar 631 is rotatably connected to the output end of the first electric push rod 632, and a second cross bar 633 is arranged between the first connecting rods 623, and the other end of the first electric push rod 632 is rotatably connected to the center position of the second cross bar 633.

[0027] Example 2

[0028] The difference from Example 1 is that Figure 3 As shown, the forming mechanism 7 includes a plurality of second electric push rods 71 ​​arranged around the upper end of the forming block 4, a pressing block 72 is arranged at the output end of the second electric push rod 71, and a convex module 73 is arranged at the center position of one end of the pressing block 72 close to the forming block 4. The purpose of controlling the up and down movement of the pressing block 72 is achieved by the extension and retraction of the second electric push rod 71. When it is necessary to form the material, the second electric push rod 71 contracts, the pressing block 72 moves downward, and the convex module 73 moves downward together and gradually enters the die groove 5, thereby achieving the purpose of pressing and forming the material.

[0029] In one embodiment, Figure 4 and Figure 5As shown, the cooling mechanism 8 includes a water tank 81 fixedly connected to the inside of the outer shell 1, a water pump 82 is arranged on one side surface of the water tank 81, and a water supply pipe 83 is connected to the output end of the water pump 82, and the water supply pipe 83 is fixedly connected to the outer surface of the forming block 4, and a water inlet pipe 84 is arranged on the surface of the water tank 81 adjacent to the installation surface of the water pump 82, and the other end of the water inlet pipe 84 is connected to the outer surface of the forming block 4, and a water flow groove 85 is opened inside the forming block 4, and the water flow groove 85 is opened around the inside of the forming block 4.

The cooling water then re-enters the water tank 81 through the water inlet pipe 84 to form a circulation, which speeds up the work efficiency and is more practical. The feeding mechanism 9 is fixedly connected to the feeding pipe 91 at the other end of the separation port 10, and the other end of the feeding pipe 91 is fixedly connected to a blower 92.

[0030] The above embodiment discloses a plastic mold structure that is easy to demold, wherein the purpose of controlling the up and down movement of the pressing block 72 is achieved by extending and retracting the second electric push rod 71. When it is necessary to mold the material, the second electric push rod 71 contracts, the pressing block 72 moves downward, and the convex module 73 moves downward together and gradually enters the concave mold groove 5, thereby achieving the purpose of pressing and molding the material. The second cross bar 633 is moved by extending and retracting the first electric push rod 632. At this time, the angle between the first connecting rod 623 and the second connecting rod 624 is reduced, the angle between the third connecting rod 625 and the fourth connecting rod 626 is reduced, the rotation angle between the first connecting rod 623 and the third connecting rod 625 is increased, and the angle between the second connecting rod 624 and the fourth connecting rod 626 is increased. The upper demolding module 61 thereby realizes the demolding operation of the molded object. After the molded object is cooled in the die groove 5, the demoulding module 61 moves upward under the control of the lifting demoulding mechanism 6, and the purpose of demoulding the molded object is successfully achieved. Then, the cooling water in the water tank 81 is pumped into the molding block 4 through the water supply pipe 83 by the water pump 82, and the cooling water flows in the water flow groove 85 in the molding block 4 to achieve the purpose of cooling the molded object in the molding block 4. The cooling water then re-enters the water tank 81 through the water inlet pipe 84 to form a cycle, which speeds up the work efficiency and is more practical. The outside air is sucked into the discharge pipe 91 through the suction pipe 93 on the blower 92, and the air is blown into the gap between the molded object and the die groove 5 by the discharge pipe 91, so as to prevent the molded object from being damaged during the demoulding process due to the adhesion between the die groove 5 and the convex module 73 due to extrusion during the pressing process.
