[0036] Furthermore, the length of the second movable plate 8 is twice the length of the first movable plate 7, and the second movable plate 8 and the first movable plate 7 are arranged crosswise with each other in a "V" shape, and the side of the discharge plate 9 is in a tight fit with the inner wall of the mold body 10; since the first movable plate 7 and the second movable plate 8 are arranged crosswise with each other, the first movable plate 7 will apply a thrust to the second movable plate 8 when it rotates, so that it drives the discharge plate 9 to slide upward along the inner wall of the mold body 10.

[0037] Furthermore, the fixing mechanism 11 includes a motor 1101, a rotating disk 1102, a first connecting rod 1103, a motion ring 1104, a second connecting rod 1105, a connecting plate 1106, a transmission disk 1107, a pull plate 1108, a slider 1109 and a clamping plate 1110. The motor 1101 is arranged above the mounting plate 4. The output end of the motor 1101 is fixedly connected to the rotating disk 1102. The first connecting rod 1103 is slidably connected inside the rotating disk 1102. The bottom of the first connecting rod 1103 is fixedly connected to the motion ring 1104.

[0038] Furthermore, the connection point between the first connecting rod 1103 and the turntable 1102 is set to deviate from the center of the turntable 1102, the angle between the first connecting rod 1103 and the turntable 1102 is 90°, and the center of the moving ring 1104 and the second connecting rod 1105 are located at the same point; because the connection point between the first connecting rod 1103 and the turntable 1102 is deviated from the center of the turntable 1102, when the turntable 1102 rotates, the moving ring 1104 will continue to slide while rotating on the surface of the second connecting rod 1105 through the first connecting rod 1103.

[0039] Furthermore, two groups of pull plates 1108 are symmetrically arranged about the center of the transmission disk 1107, and the connection points between the pull plates 1108 and the transmission disk 1107 are located at their own end points. The clamping plate 1110 forms a sliding structure on the surface of the mounting plate 4 through the pull plates 1108; when the moving ring 1104 moves, it will drive the transmission disk 1107 fixedly connected to it to swing through the connecting plate 1106. Since the two groups of pull plates 1108 deviate from the center of the transmission disk 1107, when the transmission disk 1107 swings, it will pull the two groups of sliders 1109 closer to each other, and then the clamping plate 1110 will also move toward the mold body 10 to fix the mold body 10.

[0040] Furthermore, the disassembly mechanism 12 includes a second hydraulic rod 1201, a transmission block 1202, a sliding rod 1203, a rotating plate 1204, a sliding groove 1205, an embedded rod 1206, a force plate 1207 and a slide plate 1208. The second hydraulic rod 1201 is fixedly connected to the surface of the base 1, the output end of the second hydraulic rod 1201 is fixedly connected to the transmission block 1202, the surface of the transmission block 1202 is fixedly connected to the sliding rod 1203, the surface of the sliding rod 1203 is slidably connected to the rotating plate 1204, the surface of the rotating plate 1204 is provided with a sliding groove 1205, the surface of the sliding groove 1205 is fixedly connected to the embedded rod 1206, the surface of the embedded rod 1206 is slidably connected to the force plate 1207, and the side of the force plate 1207 is fixedly connected to the slide plate 1208; by setting the disassembly mechanism 12, the mold body 10 can be easily installed and disassembled, and the mold body 10 can be removed from the mounting plate 4 for cleaning.

[0041] Furthermore, the slide groove 1205 is arranged horizontally on the surface of the rotating plate 1204, the midpoint of the rotating plate 1204 is rotationally connected to the base 1, and the rotating plate 1204 forms a rotating structure around the rotation point with the base 1 through the transmission block 1202; because the slide rod 1203 is embedded in the horizontal slide groove 1205, when the transmission slide rod 1203 rises, it will drive the rotating plate 1204 to start rotating counterclockwise around the connection point with the base 1.

[0042] Furthermore, the surfaces of the connecting block 2 and the locking block 3 are provided with grooves matching the size of the slide plate 1208, the bottom of the slide plate 1208 is slidably connected to the base 1, and the slide plate 1208 is designed in an "L" shape; the embedded rod 1206 will slide along the slideway on the surface of the force-bearing plate 1207 and drive the force-bearing plate 1207 to move toward the center position of the base 1, and then the slide plate 1208 fixedly connected thereto will slide out from the inside of the connecting block 2 and the locking block 3, and finally the locking block 3 will be taken out from the inside of the connecting block 2 to realize the disassembly of the mold body 10.

[0043] like Figure 1 As shown, this environmentally friendly plastic injection mold, when in use, first, performs the material discharging process. When the plastic processing is completed, the first hydraulic rod 5 can be opened, and then the first hydraulic rod 5 will pull the moving block 13, because the surface of the moving block 13 is provided with a convex rod embedded in the inner part of the limit plate 14. When the convex rod moves with the moving block 13, it will drive the transmission rod 6 to rotate clockwise through the limit plate 14, and then the first movable plate 7 fixedly connected thereto will rotate together. Since the first movable plate 7 and the second movable plate 8 are arranged to cross each other, the first movable plate 7 will apply a thrust to the second movable plate 8 when rotating, so that it drives the discharging plate 9 to slide upward along the inner wall of the mold body 10, and the processed plastic is ejected from the mold body 10;

[0044] Next, the mold body 10 is fixed. In order to prevent the mold body 10 from shaking during operation, the motor 1101 can be turned on, and then the turntable 1102 will start to rotate. Since the connection point between the first connecting rod 1103 and the turntable 1102 deviates from the center of the turntable 1102, when the turntable 1102 rotates, the moving ring 1104 will be driven by the first connecting rod 1103 to rotate on the surface of the second connecting rod 1105 and continue to slide. The first connecting rod 1103 will then slide inside the turntable 1102. When the moving ring 1104 moves, it will drive the transmission disk 1107 fixed to it to swing through the connecting plate 1106. Since the two sets of pull plates 1108 are deviated from the center of the transmission disk 1107, when the transmission disk 1107 swings, it will pull the two sets of sliders 1109 closer to each other, and then the splint 1110 will also move toward the mold body 10 to fix the mold body 10.

[0045] Finally, the mold body 10 is disassembled. In order to enhance its environmental performance, the mold body 10 needs to be disassembled for cleaning after being used for a period of time. The second hydraulic rod 1201 is opened to drive the transmission block 1202 to move upward. Because the slide bar 1203 is embedded in the horizontal slide groove 1205, when the transmission slide bar 1203 rises, it will drive the rotating plate 1204 to rotate counterclockwise around the connection point with the base 1, and then the embedded rod 1206 will slide along the slide on the surface of the force-bearing plate 1207 and drive the force-bearing plate 1207 to move toward the center position of the base 1, and then the slide plate 1208 fixedly connected thereto will slide out from the inside of the connecting block 2 and the locking block 3, and finally the locking block 3 is taken out from the inside of the connecting block 2 to realize the disassembly of the mold body 10.

[0046] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
