[0020] Optionally, a plastic injection molding machine facilitating mold replacement includes the following steps:

[0021] S1. First, the feeding device at the top of the triangular plate transfers the raw material from the feeding pipe directly into the injection needle rod. As the output shaft of the propulsion motor starts, it drives the injection needle rod to press downward along the slideway plate on the upper surface of the support arm, so that the raw material is injected into the mold within the mold frame. After completion, the output shaft of the rotating motor drives the shaft rod to rotate within the bearing seat. At this time, the special-shaped fan plate and the arc-shaped plate on the side surface of the shaft rod also start to rotate, and the mold frame located between the four arc-shaped plates rotates together.

[0022] S2. When the internal toothed plate on the inner wall of the arc-shaped plate contacts the linkage tooth belt, it drives the three internal linkage teeth two and the linkage rotating rod to rotate together through the linkage tooth belt. Then, the linkage tooth one on the side surface of the linkage rotating rod also starts to rotate in linkage with the meshing third downward pressure gear. The downward pressure connecting rod and the second downward pressure gear at the bottom of the third downward pressure gear are connected by a chain belt to drive the first downward pressure gear. Then, the vertical rotating rod fixedly connected to the top of the first downward pressure gear drives the first downward pressure conical tooth to rotate. Then, the second downward pressure conical tooth and the horizontal rotating rod meshingly rotate, and the downward pressure shifting tooth on the side surface of the horizontal rotating rod also rotates. Since the downward pressure shifting tooth is meshingly connected to the vertical toothed plate, the vertical toothed plate will be lifted together after the downward pressure shifting tooth rotates. During the rising process, the V-shaped plate is pulled to move horizontally by the nail rod. Since the shape of the V-shaped plate enables the nail rods on both sides of the slider to drive the L-shaped blocks to expand outward along the slide rail, the triangular clamp disengages from the side surface of the mold at this time.

[0023] S3. As the triangular clamp is disengaged from the side surface of the mold, the transmission tooth 1 meshing with the side of the linkage toothed belt drives the transmission tooth 2 and the transmission tooth 3 to adjust the direction of rotation in turn, and the single-sided tooth plate meshing with the side of the transmission tooth 3 moves forward. During the movement, the transmission tooth 3 located at the top of the single-sided tooth plate is pushed forward in the U-shaped groove plate by the moving rod. During the movement, the arc-shaped push plate at the front end of the square frame connected to the top of the straight plate is pressed to the top of the mold frame. Since the triangular clamp has been disengaged from the mold during the rotation just now, and the stopper has also been disengaged from the socket in the ramp wall, the arc-shaped push plate extending into the top of the mold frame will push the mold down from the slope of the trapezoidal block to the slideway of the discharge rack;

[0024] S4, after the mold is detached, the rotating motor is started again and the arc plate rotates again. During the rotation process, the tension of the tension spring pulls the telescopic rod and the square frame back together. This time, the outer tooth plate on the outer side of the special-shaped fan plate meshes with the propulsion tooth belt on the side of the propulsion tooth four and rotates. Then the transmission connects the propulsion tooth three and drives the propulsion tooth two to rotate. At the same time, the propulsion tooth one and the propulsion cone tooth meshing with the propulsion tooth two also start to rotate, followed by the feeding cone tooth two meshing with the propulsion cone tooth. After the feeding cone tooth two rotates, it drives the feeding rod four and the feeding cone tooth through the feeding transmission group four. The material seat 3 rotates, and rotates together with the feeding rod 1 connected to one end of the material seat 3. During the rotation process, the feeding gear 2 on one side of the feeding rod drives the feeding gear 1 and the worm to rotate through the gear. While the worm rotates, the threaded rod located in the turbine pushes the push frame to move forward in the vertical channel of the T-shaped feeding channel, and pushes the mold located in the push frame onto the ramp wall. When the L-shaped abutment plate at the bottom of the push frame contacts the ramp of the trapezoidal block, the L-shaped abutment plate shrinks along the limit rod in the L frame, which does not affect the push frame pushing the mold onto the trapezoidal block, and then the motor is rotated to continue starting;

[0025] S5. While the arc plate moves, the rack of the outer toothed plate on the outer side of the special-shaped fan plate meshes with the push-back toothed belt for transmission. After the push-back tooth four in the push-back toothed belt rotates, it passes through the added push-back tooth two. Driven by the push-back tooth three, it rotates through the push-back tooth one and the push-back cone tooth one in turn, so that the feeding cone tooth one can rotate in the opposite direction. During the rotation process, the feeding rod three successively drives the feeding transmission group three, the feeding rod two, the feeding transmission group two and the feeding rotating tooth two. The feeding rotating tooth one, which is meshed with the rack of the feeding rotating tooth two, is connected to the transmission of the worm and the turbine, which also start to rotate. During the rotation, the threaded rod rotates in the opposite direction and then retracts the push frame. At the same time, driven by the rotation of the push-back tooth belt, the push-back tooth five also starts to rotate, and the push-back tooth six at the top of the push-back tooth five drives the push-back tooth seven to rotate, wherein the push-back cone tooth two at the top of the push-back tooth seven drives the feeding cone tooth to rotate, and when the feeding rod at one end of the feeding cone tooth rotates, the feeding active tooth rotates through the feeding transmission group, and the feeding linkage group drives the feeding transmission teeth and the conveyor belt to rotate, so as to prevent slipping and send the mold into the L-shaped abutment plate along the transverse channel in the T-shaped feeding channel;

[0026] S6. After the rotating motor starts, when the inner tooth plate located within the arc-shaped plate contacts the upwardly lifting tooth belt, the upwardly lifting tooth three within the upwardly lifting tooth belt drives the upwardly lifting tooth two to rotate. The driven tooth two engaged with the upwardly lifting tooth two drives the driven rotating rod and the driven tooth one to rotate. The driven tooth one drives the upwardly lifting tooth one to rotate. While the upwardly lifting tooth one rotates, it drives the downward pressing gear three to rotate. Compared with the linkage tooth one directly driving the downward pressing gear three to rotate, with one more set of gear linkages through the driven tooth one, it can make the downward pressing gear three rotate in the reverse direction, causing the vertical tooth plate to start moving downward. The vertical tooth plate uses the V-shaped plate to close the L-shaped block inward to clamp the mold, and the stop block protrudes from the socket to limit and strengthen the fixation of the mold.

[0027] The present invention provides an injection molding machine that facilitates mold replacement, having the following beneficial effects:

[0028] 1. For this injection molding machine that facilitates mold replacement, through the V-shaped plate, limiting rotating rod, and nail rod structure within the mold fixing component, driven by the up and down movement of the vertical tooth plate, it can link the slider to close and expand within the slide rail. Using the V-shaped plate structure, during the up and down movement of the vertical tooth plate, it can automatically open or close the triangular clamp and the stop block, which helps to cooperate with the linkage of the downward pressing gear component and the upwardly lifting gear set.

[0029] 2. For this injection molding machine that facilitates mold replacement, through the outer tooth plate of the special-shaped fan plate and the inner tooth plate of the arc-shaped plate, driven by the rotating motor, they can respectively mesh and link with the propulsion gear set, the back-pushing gear set, the downward pressing gear component, the linkage gear set, and the upwardly lifting gear set. Driven by these gear sets, it can open and close the mold fixing component, and on the other hand, it can automatically load and replenish the mold.

[0030] 3. For this injection molding machine that facilitates mold replacement, through the tension spring and the telescopic rod within the feeding component, driven by the inner tooth plate to the linkage gear set, while the mold fixing component is opened, the transmission tooth three drives the single-sided tooth plate to move forward. The arc-shaped push plate can push out the mold, and after pushing, it squeezes the spring to pull the telescopic rod to automatically reset, thereby achieving automatic discharging and automatic resetting.

[0031] 4. For this injection molding machine that facilitates mold replacement, through the linkage of the outer tooth plate with the propulsion gear set, it can automatically push the mold within the pushing frame of the feeding component into the vacated mold fixing component. Then, while the back-pushing gear set can retract the pushing frame, it can also convey the mold to the pushing frame through the replenishing component for the next mold loading.

[0032] 5. The injection molding machine facilitating mold replacement, through the linkage of multiple toothed plates and gear sets, helps with automatic mold replacement, saving the operation of the staff. While being easy to operate, in the empty space before injection molding, it is convenient for the staff to observe and repair whether there are problems with the mold, and it can be modified in time, with a certain time for remedial measures.

[0071] S1. First, the feeding device 303 at the top of the triangular plate 2 transfers raw materials from the feeding pipe 302 directly into the injection needle rod 304. As the output shaft of the propulsion motor 307 starts, it drives the injection needle rod 304 to press downward along the slideway plate 306 on the upper surface of the support arm 305, so that the raw materials are injected into the mold in the mold frame 1501. After completion, the output shaft of the rotating motor 501 drives the shaft rod 502 to rotate in the bearing seat 503. At this time, the special-shaped fan plate 13 and the arc-shaped plate 14 on the side surface of the shaft rod 502 also start to rotate, and the mold frame 1501 located between the four arc-shaped plates 14 rotates together;

[0072] S2, the inner tooth plate 17 on the inner wall of the arc plate 14 contacts the linkage tooth belt 2005, and the linkage tooth belt 2005 drives the three internal linkage teeth 2 2004 and the linkage rotating rod 2001 to rotate together, and then the linkage tooth 1 2003 on the side surface of the linkage rotating rod 2001 also starts to rotate in conjunction with the meshing downward pressure gear 3 1810, wherein the downward pressure connecting rod 1809 and the downward pressure gear 2 1808 at the bottom of the downward pressure gear 3 1810 are connected to the downward pressure gear 1 1803 through the chain belt 1807 transmission, and then the vertical rotating rod 1801 fixedly connected to the top of the downward pressure gear 1 1803 rotates with the downward pressure conical tooth 1 1802, Then the meshing linkage pressing cone-shaped tooth 2 1804 and the horizontal rotating rod 1805 rotate, and the pressing tooth 1806 on the side surface of the horizontal rotating rod 1805 is also rotated. Since the pressing tooth 1806 and the vertical tooth plate 1511 are meshingly connected, the pressing tooth 1806 will make the vertical tooth plate 1511 rise together after the rotation, and use the nail rod 1509 to pull the V-shaped plate 1508 to move horizontally during the rising process. Due to the shape of the V-shaped plate 1508, the nail rods 1509 on both sides of the slider 1504 can drive the L-shaped block 1505 to expand outward along the slide rail 1503. At this time, the triangular clamp 1506 is detached from the side surface of the mold.

[0073] S3. As the triangular clamp 1506 is separated from the side surface of the mold, the transmission tooth 1 2006 meshing with the side of the linkage toothed belt 2005 drives the transmission tooth 2 2007 and the transmission tooth 3 2008 to adjust the direction of rotation in turn, and the single-sided tooth plate 2310 meshing with the side of the transmission tooth 3 2008 moves forward. During the movement, the transmission tooth 3 2008 located at the top of the single-sided tooth plate 2310 is simultaneously pushed forward in the U-shaped groove plate 2307 by the moving rod 2309. During the movement, the arc-shaped push plate 2306 at the front end of the square frame 2305 connected to the top of the straight plate 2308 is pressed to the top of the mold frame 1501. Since the triangular clamp 1506 has been separated from the mold during the rotation just now, and the stopper 1514 has also been separated from the socket 1515 in the ramp wall 1513, the arc-shaped push plate 2306 extending into the top of the mold frame 1501 will push the mold down from the slope of the trapezoidal block 1512 to the slideway of the discharge rack 6;

[0074] S4. After the mold is separated, the rotating motor 501 starts again and the arc-shaped plate 14 rotates again. During the rotation, due to the pulling force of the tension spring 2304, the telescopic rod 2303 and the square frame 2305 are pulled back together. This time, the external tooth plate 16 on the outer side of the special-shaped fan plate 13 meshes with the driving tooth belt 1107 on the side of the driving tooth four 1108 and rotates, then drives the connection to the driving tooth three 1106 and drives the driving tooth two 1104 to rotate. At the same time, the driving tooth one 1103 and the driving conical tooth 1102 meshing with the driving tooth two 1104 also start to rotate. Then, the feeding conical tooth two 9028 meshing with the driving conical tooth 1102 also starts to rotate. After the feeding conical tooth two 9028 rotates, it drives the feeding rod four 9023 and the feeding seat three 9024 to rotate through the feeding transmission group four 9025, and rotates together with the feeding rod one 9013 connected to one end of the feeding seat three 9024. During the rotation, the feeding rotating tooth two 9012 on the side surface of the feeding rod one 9013 drives the feeding rotating tooth one 9011 and the worm 909 through gears. While the worm 909 rotates, the threaded rod 903 located in the turbine 902 pushes the pushing frame 904 to move forward in the vertical channel of the T-shaped feeding channel 8, and pushes the mold located in the pushing frame 904 onto the ramp wall 1513. When the L-shaped abutting plate 907 at the bottom of the pushing frame 904 touches the inclined path of the trapezoidal block 1512, the L-shaped abutting plate 907 contracts along the limiting rod 906 in the L-shaped frame 905, without affecting the pushing frame 904 to push the mold onto the trapezoidal block 1512, and then the rotating motor 501 continues to start;

[0075] S5. While the arc plate 14 moves, the rack of the outer tooth plate 16 on the outer side of the special-shaped fan plate 13 meshes with the push-back tooth belt 1209 for transmission. After the push-back tooth four 1208 in the push-back tooth belt 1209 rotates, it passes through the added push-back tooth two 1204, and driven by the push-back tooth three 1206, it rotates in turn through the push-back tooth one 1203 and the push-back conical tooth one 1202, so that the feeding conical tooth one 9022 can rotate in the opposite direction. During the rotation, the feeding rod three 9019 successively drives the feeding transmission group three 9018, the feeding rod two 9017, the feeding transmission group two 9016 and the feeding rotating tooth two 9012, and the feeding rotating tooth one 9011 meshed with the rack of the feeding rotating tooth two 9012 is also driven by the worm 909 and the turbine 902. During the rotation, the threaded rod 903 rotates in the opposite direction and then retracts the push frame 904. At the same time, driven by the rotation of the push-back tooth belt 1209, the push-back tooth five 1210 also starts to rotate, and the push-back tooth six 1212 at the top of the push-back tooth five 1210 drives the push-back tooth seven 1213 to rotate, wherein the push-back cone tooth two 1215 at the top of the push-back tooth seven 1213 drives the feeding cone tooth 1005 to rotate, and when the feeding rod 1004 located at one end of the feeding cone tooth 1005 rotates, the feeding active tooth 1001 is rotated through the feeding transmission group 1003, and the feeding linkage group 1009 is used to drive the feeding transmission tooth 1007 and the conveyor belt 1006 to rotate, so as to prevent slipping and send the mold along the transverse channel in the T-shaped feeding channel 8 onto the L-shaped abutment plate 907;

[0076] S6. After the rotating motor 501 is started, the inner tooth plate 17 located in the arc plate 14 contacts the upper lifting tooth belt 2109, and the upper lifting tooth 2 2106 is driven to rotate by the upper lifting tooth 3 2108 in the upper lifting tooth belt 2109, and the driven tooth 2 2105 meshing with the upper lifting tooth 2 2106 drives the driven rotating rod 2102 and the driven tooth 1 2104 to rotate, and the driven tooth 1 2104 drives the upper lifting tooth 1 2103 to rotate, and at the same time as the upper lifting tooth 1 2103 rotates, the driven tooth 2 2105 drives the driven rotating rod 2102 and the driven tooth 1 2104 to rotate. The downward pressure gear three 1810 rotates, and compared with the linkage gear one 2003 which directly drives the downward pressure gear three 1810 to rotate, through an additional set of gear linkages of the driven gear one 2104, the downward pressure gear three 1810 can rotate in the opposite direction, so that the vertical tooth plate 1511 starts to move downward, so that the vertical tooth plate 1511 uses the V-shaped plate 1508 to close the L-shaped block 1505 inward to clamp the mold, and the stop block 1514 protrudes from the socket 1515 to limit and strengthen the fixation of the mold.

[0077] In summary, when the injection molding machine is easy to replace molds, the feeding device 303 on the top of the triangular plate 2 first transfers the raw material from the feeding tube 302 to the injection needle rod 304, and as the output shaft of the propulsion motor 307 starts, the injection needle rod 304 is driven to press downward along the slide plate 306 on the upper surface of the support arm 305, so that the raw material is injected into the mold in the mold frame 1501. After completion, the output shaft of the rotating motor 501 drives the shaft rod 502 to rotate in the bearing seat 503. At this time, the special-shaped fan plate 13 and the arc plate 14 on the side surface of the shaft rod 502 also start to rotate, and the mold frame 1501 located between the four arc plates 14 rotates together, and the inner tooth plate 17 on the inner wall of the arc plate 14 contacts the linkage tooth belt 2005, which drives the internal three The linkage tooth 2004 rotates together with the linkage rotating rod 2001, and then the linkage tooth 1 2003 on the side surface of the linkage rotating rod 2001 also starts to rotate in conjunction with the meshing downward pressure gear 3 1810, wherein the downward pressure connecting rod 1809 and the downward pressure gear 2 1808 at the bottom of the downward pressure gear 3 1810 are connected to the downward pressure gear 1 1803 through the chain belt 1807 transmission, and then the vertical rotating rod 1801 fixedly connected to the top of the downward pressure gear 1 1803 rotates with the downward pressure conical tooth 1 1802, and then the meshing linkage downward pressure conical tooth 2 1804 and the horizontal rotating rod 1805 rotate, and the downward pressure shifting tooth 1806 on the side surface of the horizontal rotating rod 1805 is also rotated. Since the downward pressure shifting tooth 1806 and the vertical tooth plate 1511 are meshingly connected, After the downward pressing and pulling tooth 1806 rotates, the vertical tooth plate 1511 will be lifted up together, and the nail rod 1509 will be used to pull the V-shaped plate 1508 to move horizontally during the rising process. Due to the shape of the V-shaped plate 1508, the nail rods 1509 on both sides of the slider 1504 can drive the L-shaped block 1505 to expand outward along the slide rail 1503. At this time, the triangular clamp 1506 is separated from the side surface of the mold. As the triangular clamp 1506 is separated from the side surface of the mold, the transmission tooth 1 2006 engaged with the side of the linkage toothed belt 2005 drives the transmission tooth 2 2007 and the transmission tooth 3 2008 to adjust the direction and rotate in turn, and the single-sided tooth plate 2310 engaged with the side of the transmission tooth 3 2008 moves forward. During the movement, the transmission tooth 3 located at the top of the single-sided tooth plate 2310 2308 is pushed forward in the U-shaped groove plate 2307 by the moving rod 2309. During the movement, the arc-shaped push plate 2306 at the front end of the square frame 2305 connected to the top of the straight plate 2308 is pressed forward to the top of the mold frame 1501. Since the triangular clamp 1506 has been detached from the mold during the rotation just now, and the stopper 1514 has also been detached from the socket 1515 in the ramp wall 1513, the arc-shaped push plate 2306 extending into the top of the mold frame 1501 will push the mold from the slope of the trapezoidal block 1512 downward to the slideway of the discharge rack 6. After the mold is detached, the rotating motor 501 is started again and the arc plate 14 is rotated again. During the rotation, the tension of the tension spring 2304 pulls the telescopic rod 2303 and the square frame 2305 back together.This time, the external tooth plate 16 on the outer side of the special-shaped fan plate 13 meshes with the driving tooth belt 1107 on the side of the driving tooth four 1108 and rotates, then drives the connection to the driving tooth three 1106 and drives the driving tooth two 1104 to rotate. At the same time, the driving tooth one 1103 and the driving conical tooth 1102 that mesh with the driving tooth two 1104 also start to rotate. Then, the feeding conical tooth two 9028 that meshes with the driving conical tooth 1102 also starts to rotate. When the feeding conical tooth two 9028 rotates, it drives the feeding rod four 9023 and the feeding seat three 9024 to rotate through the feeding transmission group four 9025, and rotates together with the feeding rod one 9013 connected to one end of the feeding seat three 9024. During the rotation process, the feeding rotating tooth two 9012 on the side surface of the feeding rod one 9013 drives the feeding rotating tooth one 9011 and the worm 909 through gears. While the worm 909 rotates, the threaded rod 903 located inside the turbine 902 pushes the pushing frame 904 to move forward in the vertical channel of the T-shaped feeding channel 8, and pushes the mold located inside the pushing frame 904 onto the ramp wall 1513. When the L-shaped abutting plate 907 at the bottom of the pushing frame 904 contacts the inclined path of the trapezoidal block 1512, the L-shaped abutting plate 907 contracts along the limiting rod 906 inside the L-shaped frame 905, without affecting the pushing frame 904 to push the mold onto the trapezoidal block 1512. Then, the rotating motor 501 continues to start. While the arc-shaped plate 14 moves, the rack of the external tooth plate 16 on the outer side of the special-shaped fan plate 13 meshes and drives the return pushing tooth belt 1209. After the return pushing tooth four 1208 inside the return pushing tooth belt 1209 rotates, through the added return pushing tooth two 1204, driven by the return pushing tooth three 1206, it rotates successively through the return pushing tooth one 1203 and the return pushing conical tooth one 1202, enabling the feeding conical tooth one 9022 to rotate in the reverse direction. During the rotation process, the feeding rod three 9019 successively drives the feeding transmission group three 9018, the feeding rod two 9017, the feeding transmission group two 9016, and the feeding rotating tooth two 9012. The worm 909 and the turbine 902 driven by the feeding rotating tooth one 9011 connected by the rack meshing of the feeding rotating tooth two 9012 also start to rotate. During the rotation process, the threaded rod 903 rotates in the reverse direction and then retracts the pushing frame 904. At the same time, while the return pushing tooth belt 1209 rotates, the return pushing tooth five 1210 also starts to rotate. The return pushing tooth six 1212 at the top of the return pushing tooth five 1210 drives the return pushing tooth seven 1213 to rotate. Among them, the return pushing conical tooth two 1215 at the top of the return pushing tooth seven 1213 drives the replenishing conical tooth 1005 to rotate. When the replenishing rod 1004 at one end of the replenishing conical tooth 1005 rotates, it enables the replenishing driving tooth 1001 to rotate through the replenishing transmission group 1003, and drives the replenishing transmission tooth 1007 and the conveyor belt 1006 to rotate by using the replenishing linkage group 1009, preventing slipping and sending the mold along the horizontal channel in the T-shaped feeding channel 8 onto the L-shaped abutting plate 907. When the rotating motor 501 starts, after the internal tooth plate 17 inside the arc-shaped plate 14 contacts the lifting tooth belt 2109,By lifting the upper lifting tooth three 2108 inside the lifting tooth belt 2109 to drive the rotation of the upper lifting tooth two 2106, the driven tooth two 2105 engaged with the upper lifting tooth two 2106 drives the rotation of the driven rotating rod 2102 and the driven tooth one 2104. The driven tooth one 2104 is used to drive the rotation of the upper lifting tooth one 2103. While the upper lifting tooth one 2103 is rotating, it drives the rotation of the lower pressing gear three 1810. Compared with the linkage tooth one 2003 directly driving the lower pressing gear three 1810, through one more set of gear linkage of the driven tooth one 2104, the lower pressing gear three 1810 can rotate in the reverse direction, causing the vertical tooth plate 1511 to start moving downward. The vertical tooth plate 1511 uses the V-shaped plate 1508 to close the L-shaped block 1505 inward to clamp the mold, and the stop block 1514 protrudes from the socket 1515 to limit and strengthen the fixation of the mold.

10. A method for using an injection molding machine that is convenient for replacing molds, using the injection molding machine that is convenient for replacing molds as claimed in any one of claims 1 to 9, characterized in that: The steps include: S1. First, the feeding device (303) on the top of the triangular plate (2) transfers the raw material from the feeding tube (302) to the injection needle rod (304). As the output shaft of the propulsion motor (307) starts, it drives the injection needle rod (304) to be pressed downward along the slide plate (306) on the upper surface of the support arm (305), so that the raw material is injected into the mold in the mold frame (1501). After completion, the output shaft of the rotating motor (501) drives the shaft rod (502) to rotate in the bearing seat (503). At this time, the special-shaped fan plate (13) and the arc plate (14) on the side surface of the shaft rod (502) also start to rotate, and the mold frame (1501) located between the four arc plates (14) rotates together; S2, the inner tooth plate (17) on the inner wall of the arc-shaped plate (14) contacts the linkage tooth belt (2005), and the linkage tooth belt (2005) drives the three internal linkage teeth 2 (2004) and the linkage rotating rod (2001) to rotate together, and then the linkage tooth 1 (2003) on the side surface of the linkage rotating rod (2001) also starts to rotate in conjunction with the meshing downward pressure gear 3 (1810), wherein the downward pressure connecting rod (1809) and the downward pressure gear 2 (1808) at the bottom of the downward pressure gear 3 (1810) are connected to the downward pressure gear 1 (1803) through the chain belt (1807), and then the vertical rotating rod (1801) fixedly connected to the top of the downward pressure gear 1 (1803) rotates with the downward pressure conical tooth 1 (1802) , and then the meshing linkage downward pressing conical tooth 2 (1804) and the horizontal rotating rod (1805) rotate, and the downward pressing tooth (1806) on the side surface of the horizontal rotating rod (1805) is also driven to rotate. Since the downward pressing tooth (1806) and the vertical tooth plate (1511) are meshingly connected, the rotation of the downward pressing tooth (1806) will cause the vertical tooth plate (1511) to be lifted together, and in the process of rising, the nail rod (1509) is used to pull the V-shaped plate (1508) to move laterally. Due to the shape of the V-shaped plate (1508), the nail rods (1509) on both sides of the slider (1504) can drive the L-shaped block (1505) to expand outward along the slide rail (1503), and at this time, the triangular clamp (1506) is detached from the side surface of the mold; S3. As the triangular clamp (1506) is detached from the side surface of the mold, the transmission tooth 1 (2006) meshed with the side of the linkage toothed belt (2005) drives the transmission tooth 2 (2007) and the transmission tooth 3 (2008) to adjust the direction of rotation in turn, and the single-sided tooth plate (2310) meshed with the side of the transmission tooth 3 (2008) moves forward. During the movement, the transmission tooth 3 (2008) located at the top of the single-sided tooth plate (2310) is simultaneously pushed forward in the U-shaped groove plate (2307) through the moving rod (2309). During the movement, the arc-shaped push plate (2306) at the front end of the square frame (2305) connected to the top of the straight plate (2308) is pressed to the top of the mold frame (1501). Since the triangular clamp (1506) has been separated from the mold during the rotation just now, and the stopper (1514) has also been separated from the socket (1515) in the ramp wall (1513), the arc-shaped push plate (2306) extending into the top of the mold frame (1501) will push the mold down from the slope of the trapezoidal block (1512) to the slideway of the discharge rack (6); S4, after the mold is separated, the rotating motor (501) is started again and the arc plate (14) is rotated again. During the rotation process, the tension of the tension spring (2304) pulls the telescopic rod (2303) and the square frame (2305) back together. This time, the outer tooth plate (16) on the outer side of the special-shaped fan plate (13) is meshed and rotated with the propulsion tooth belt (1107) on the side of the propulsion tooth four (1108), and then the transmission is connected to the propulsion tooth three (1106). The second propelling tooth (1104) is driven to rotate, and the first propelling tooth (1103) and the propelling cone tooth (1102) meshing with the second propelling tooth (1104) also start to rotate, and then the second feeding cone tooth (9028) meshing with the propelling cone tooth (1102) also starts to rotate. When the second feeding cone tooth (9028) rotates, it drives the fourth feeding rod (9023) and the third feeding seat (9024) through the fourth feeding transmission group (9025). ) rotates, and rotates together with the feeding rod 1 (9013) connected to one end of the feeding seat 3 (9024). During the rotation process, the feeding rotating tooth 2 (9012) on the side surface of the feeding rod 1 (9013) drives the feeding rotating tooth 1 (9011) and the worm (909) to rotate through the gear. When the worm (909) rotates, the threaded rod (903) located in the turbine (902) pushes the push frame (904) to move vertically in the T-shaped feeding channel (8). Move forward into the channel to push the mold in the pusher frame (904) onto the ramp wall (1513). When the L-shaped abutment plate (907) at the bottom of the pusher frame (904) contacts the ramp of the trapezoidal block (1512), the L-shaped abutment plate (907) contracts along the limit rod (906) in the L frame (905) without affecting the pusher frame (904) pushing the mold onto the trapezoidal block (1512). Then the motor (501) is rotated to continue starting. S5. While the arc-shaped plate (14) is moving, the toothed rack of the outer toothed plate (16) outside the special-shaped fan plate (13) meshes with the push-back toothed belt (1209), and the push-back toothed belt (1209) rotates and passes through the added push-back toothed belt (1204), and is driven by the push-back toothed belt (1206), and then passes through the push-back toothed belt (1203) and the push-back cone toothed belt (1202) to rotate downward. , which can make the feeding cone tooth 1 (9022) rotate in the opposite direction. During the rotation process, the feeding rod 3 (9019) successively drives the feeding transmission group 3 (9018), the feeding rod 2 (9017), the feeding transmission group 2 (9016) and the feeding rotating tooth 2 (9012). The feeding rotating tooth 1 (9011) connected to the rack meshing with the feeding rotating tooth 2 (9012) and the worm (909) and the turbine (902) also start During the rotation, the threaded rod (903) rotates in the opposite direction and then retracts the push frame (904). At the same time, under the rotation of the push-back tooth belt (1209), the push-back tooth five (1210) also starts to rotate, and the push-back tooth six (1212) at the top of the push-back tooth five (1210) drives the push-back tooth seven (1213) to rotate, wherein the push-back cone tooth two (1215) at the top of the push-back tooth seven (1213) drives the feeding cone tooth (1005) rotates, and when the feeding rod (1004) located at one end of the feeding conical tooth (1005) rotates, the feeding driving tooth (1001) rotates through the feeding transmission group (1003), and the feeding linkage group (1009) drives the feeding transmission tooth (1007) and the conveyor belt (1006) to rotate, so as to prevent slipping and send the mold along the transverse channel in the T-shaped feeding channel (8) onto the L-shaped abutment plate (907); S6. After the rotating motor (501) is started, the inner tooth plate (17) located in the arc plate (14) contacts the upper lifting tooth belt (2109), and the upper lifting tooth 2 (2106) is driven to rotate by the upper lifting tooth 3 (2108) in the upper lifting tooth belt (2109), and the driven tooth 2 (2105) meshing with the upper lifting tooth 2 (2106) drives the driven rotating rod (2102) and the driven tooth 1 (2104) to rotate, and the driven tooth 1 (2104) drives the upper lifting tooth 1 (2103) to rotate. When the upper lifting tooth 1 (2103) rotates, To drive the downward pressure gear three (1810) to rotate, compared with the linkage gear one (2003) directly driving the downward pressure gear three (1810) to rotate, through the driven gear one (2104) with one more set of gear linkage, the downward pressure gear three (1810) can rotate in the opposite direction, so that the vertical tooth plate (1511) starts to move downward, so that the vertical tooth plate (1511) uses the V-shaped plate (1508) to close the L-shaped block (1505) inward to clamp the mold, and the stopper (1514) protrudes from the socket (1515) to limit and strengthen the fixation of the mold.
