On one side of the frame 1, a primary mold mechanism 2 is provided, and on the other side, a forming mold mechanism 3 is provided. A flipping mechanism 4 is also provided between the primary mold mechanism 2 and the forming mold mechanism 3. The flipping mechanism 4 flips the primary embryo formed by the primary mold mechanism 2 onto the forming mold mechanism 3. Above the frame 1, a servo material distribution mechanism 5 is provided. The servo material distribution mechanism 5 is docked with the primary mold mechanism 2 through a material chute 6 to distribute the dripping material into the primary mold mechanism 2.

[0026] In this embodiment, there are three sets of both the primary mold mechanism 2 and the forming mold mechanism 3, and they are arranged side by side. Other numbers of sets can also be set according to needs.

[0027] As Figure 3-5 As shown in the figure, the primary mold mechanism 2 includes a primary mold gripper 7 and a first air cylinder 8 for driving the opening and closing of the primary mold gripper 7. Two primary mold grippers 7 form a group and perform the opening and closing actions simultaneously to complete the forming of the primary embryo. The first air cylinder 8 is fixed on the bottom plate of the frame 1. The output end of the first air cylinder 8 is connected with a first connecting rod 9. The first connecting rod 9 is hinged with a three-hole hinge 10. The middle part of the three-hole hinge 10 is sleeved on a first guiding shaft 11. The first guiding shaft 11 is installed on the bottom plate of the frame 1. The three-hole hinge 10 can rotate along the first guiding shaft 11. Three connecting claws are arranged circumferentially on the three-hole hinge 10. Two of them are arranged at a certain angle for connecting with the two primary mold grippers 7, and the other is hinged with the first connecting rod 9. One end of each of the two connecting claws connected with the primary mold grippers 7 is hinged with one end of a second connecting rod 12. The other end of the second connecting rod 12 is hinged with a spline sleeve 13. The spline sleeve 13 is fixedly sleeved on a first rotating shaft 14. One end of the first rotating shaft 14 is connected with the bottom plate of the frame 1 through a bearing seat 15. In this way, the first air cylinder 8 drives the first connecting rod 9 to move, the first connecting rod 9 drives the three-hole hinge 10 to swing, and the three-hole hinge 10 drives the first rotating shaft 14 to rotate through the second connecting rod 12. A first support 16 is fixedly installed on the frame 1. The first support 16 is used for installing the primary mold gripper 7. The upper end of the first rotating shaft 14 passes through the first support 16 and is fixedly connected with a rocker arm 17. One end of the rocker arm 17 is fixedly connected with the first rotating shaft 14, and the other end is hinged with a third connecting rod 18. The third connecting rod 18 is hinged with the primary mold gripper 7. The primary mold gripper 7 is of the shearing type and the opening faces the forming mold mechanism 3, which is convenient for the transfer of the primary embryo. The end of the primary mold gripper 7 far from the opening is sleeved on a second guiding shaft 19. In this embodiment, the second guiding shaft 19 is installed on the first support 16. The hinged position of the third connecting rod 18 and the primary mold gripper 7 is between the second guiding shaft 19 and the opening. In this way, when the first rotating shaft 14 rotates, it drives the rocker arm 17 to swing, pulling the third connecting rod 18 to move, realizing the opening and closing of the primary mold gripper 7.

[0028] A gas-puffing mechanism and a funnel mechanism are also provided at the primary mold mechanism 2. The gas-puffing mechanism and the funnel mechanism are respectively arranged above the primary mold gripper 7 and are respectively used for gas-puffing and receiving the embryo material.

[0029] As Figure 3and Figure 6 As shown in Figure 6 , the molding mechanism 3 includes a molding gripper 20 and a second cylinder 21 for driving the molding gripper 20 to open and close. The transmission mode of the molding gripper 20 and the second cylinder 21 is the same as that of the primary mold gripper 7 and the first cylinder 8, which will not be elaborated here. The molding gripper 20 of the primary mold gripper 7 adopts the same transmission mode and uses the same parts, improving the common rate of parts and facilitating maintenance and replacement of parts. The molding gripper 20 is arranged to open towards the direction away from the primary mold gripper 7, facilitating the removal of the formed embryo. The molding gripper 20 is installed on the frame 1 through a second bracket 22. In this embodiment, the second bracket 22 is fixed on the frame 1.

[0030] The flipping mechanism 4 includes a second rotating shaft 23. The second rotating shaft 23 is connected with a gear 24 and a rack 25 for driving its rotation. The gear 24 is fixedly sleeved on the second rotating shaft 23. The rack 25 is connected with a third cylinder 26 for driving its up and down movement. The third cylinder 26 is fixedly connected to the frame 1. A cylinder head 27 is also arranged on the third cylinder 26. The cylinder head 27 is arranged vertically and internally provided with a channel for the rack 25 to slide up and down. The rack 25 is installed in the channel. The lower end of the rack 25 is connected with the piston disc of the third cylinder 26. The third cylinder 26 drives the rack 25 to slide vertically in the cylinder head 27. A through groove is formed on one side of the cylinder head 27 close to the second rotating shaft 23. The second rotating shaft 23 is sleeved with the gear 24 at the through groove. The gear 24 meshes with the rack 25. The rack 25 slides up and down, driving the rotation of the gear 24, thereby driving the rotation of the second rotating shaft 23.

[0031] Both ends of the second rotating shaft 23 are installed on the second bracket 22 through bearing sleeves. In this way, the molding gripper 20 and the entire flipping mechanism 4 are both installed on the second bracket, with fewer overall parts and a more compact structure. A fourth cylinder 28 is fixedly sleeved on the second rotating shaft 23. A die holder clamp 29 is arranged on the fourth cylinder 28. In this embodiment, two die holder clamps 29 are arranged, and correspondingly two fourth cylinders 28 are also arranged. The two fourth cylinders 28 are respectively located on both sides of the gear 24. The two fourth cylinders 28 act simultaneously in opposite directions, realizing the mutual approach or separation of the die holder clamps 29, completing the closing and opening of the mouth clamp. The rotating shaft rotates, driving the die holder clamp 29 to flip, realizing the flipping of the primary embryo.

[0032] A positive air blowing mechanism 30 is also arranged at the molding mechanism 3 for blowing air on the primary embryo to complete the production of the formed embryo.

[0033] As Figure 3As shown, a movable bottle clamping fixture 31 is further arranged on the frame 1. The bottle clamping fixture 31 is a pneumatic switch clamp. The bottle clamping fixture 31 is connected to a cantilever 32. The cantilever 32 is connected to a motor that drives its swing. The motor is a servo motor 33. The servo motor 33 is connected to one end of the cantilever 32, and the bottle clamping fixture 31 is connected to the other end of the cantilever 32. The servo motor 33 controls the cantilever 32 to control the bottle clamping fixture 31. When the bottle clamping fixture 31 is away from the molding mechanism 3, space is vacated for the flipping mechanism 4 to drive the preform into the molding mechanism 3. By driving the bottle clamping fixture 31 through the cantilever 32, compared with linear motion, no guide is required, the structure is simpler, and the swing can realize motion in both horizontal and vertical directions at the same time. Compared with linear motion, a set of power devices is saved, and the cost is more saved.

[0034] In this embodiment, a set of preform grippers 7 is arranged on each preforming mechanism 2, and correspondingly, a set of molding grippers 20 is also arranged on the molding mechanism 3. Compared with the original double-drop 140 model, the maximum volume can reach 8L, greatly improving the applicability of the whole machine.

[0035] As Figure 2 As shown, it further includes an air plate 34. The air plate 34 is arranged on the side of the molding mechanism 3 away from the preforming mechanism 2. The bottle clamping fixture 31 clamps the mold out of the molding mechanism 3 and places it on the air plate 34. Multiple cooling air holes are arranged on the air plate 34 for cooling the formed embryo. The air plate 34 is connected to an air box 36 through an air duct 35. An air vent 37 is arranged on the air box 36. Airflow enters the air box 36 through the air vent 37 and then flows out from the cooling air holes on the air plate 34 through the air duct 35 to realize the cooling of the formed embryo.
