The conveyor belt is used to convey the upper die. When the upper die is being formed, its opening faces upward and needs to be flipped to align with the lower die. Therefore, the upper die needs to pass through the flipping member during the conveyance by the conveyor belt. The flipping member is arranged in the avoidance space, and only the first flipping frame and the second flipping frame can affect the conveyance of the upper die on the conveyor belt. When the upper die is conveyed to the first flipping frame, the upper die will be flipped by 90 degrees, reach the second flipping frame, and be flipped by 90 degrees again to achieve a 180-degree flip, ensuring that the upper die whose original opening faces upward now has its opening facing downward, facilitating docking with the lower die. The realization through two flips reduces the amplitude of each flip, improves the quality and effect of the flip. At the same time, it reduces the difficulty of flipping, reduces the overall volume of the equipment, and saves the manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Refer to Figures 1 to 5, which is the first embodiment of the present utility model, provides a mold closing machine for molding, which is used to combine the upper mold 110 and the lower mold 120, and includes: There are several conveyor belts 210, which are arranged on the frame 2. The conveyor belt 210 is used to convey the upper mold 110, and there is an avoidance space 220 between the several conveyor belts 210; The connecting frame 310 is located in the avoidance space 220; The first flipping frame 320 is rotatably arranged on the connecting frame 310. After the first flipping frame 320 rotates, it abuts against and drives the upper mold 110 to flip; The second flipping frame 330 is rotatably arranged on the connecting frame 310. After the first flipping frame 320 drives the upper mold 110 to flip, the upper mold 110 abuts against the second flipping frame 330, and the second flipping frame 330 is used to drive the upper mold 110 to further flip.

[0046] In this embodiment, the frame 2 is used to support the conveyor belt 210 and the flipping member 3, ensuring that the conveyor belt 210 can convey stably while the flipping member 3 can also work stably. The conveyor belt 210 is used to convey the upper mold 110. When the upper mold 110 is molded, its opening faces upward and needs to be flipped before it can be aligned with the lower mold 120. Therefore, the upper mold 110 needs to pass through the flipping member 3 during the conveying process by the conveyor belt 210. The flipping member 3 is arranged in the avoidance space 220, and only the first flipping frame 320 and the second flipping frame 330 can affect the conveying of the upper mold 110 on the conveyor belt 210. When the upper mold 110 is conveyed to the first flipping frame 320, the upper mold 110 will be flipped 90 degrees, then continue to be conveyed to the second flipping frame 330 and be flipped 90 degrees again to achieve a 180-degree flip, ensuring that the upper mold 110 with the original opening facing upward has its opening facing downward, which is convenient for docking with the lower mold 120. Achieved through two flips, the amplitude of each flip is reduced, improving the quality and effect of flipping. At the same time, the difficulty of flipping is reduced, the overall volume of the equipment is reduced, and the manufacturing cost is saved.

[0047] As a further technical solution, the first flipping frame 320 is integrally L-shaped and further includes: a plurality of first support blocks 321 disposed on the connecting frame 310; a plurality of first rotating blocks 322 disposed on the first flipping frame 320, and the first support block 321 is hinged to the first rotating block 322; a plurality of first telescopic members 323, one end of the first telescopic member 323 is rotatably disposed on the connecting frame 310, the first telescopic member 323 has a first telescopic end 3231, and the first telescopic end 3231 is hinged to an end of the first flipping frame 320 away from the first rotating block 322. The second flipping frame 330 is also L-shaped and further includes: a plurality of second support blocks 331 disposed on the connecting frame 310; a plurality of second rotating blocks 332 disposed on the second flipping frame 330, and the second support block 331 is hinged to the second rotating block 332; a plurality of second telescopic members 333, one end of the second telescopic member 333 is rotatably disposed on the connecting frame 310, the second telescopic member 333 has a second telescopic end 3331, and the second telescopic end 3331 is hinged to an end of the second flipping frame 330 away from the second rotating block 332.

[0048] In this embodiment, the structures of the first rotating frame and the second rotating frame are basically the same, both are L-shaped. The rotation of the frame body 2 is realized through the first rotating block 322 or the second rotating block 332 disposed at the L-shaped center, so as to ensure that the upper die 110 located on the frame body 2 can follow the frame body 2 to achieve a 90-degree rotation. The first telescopic member 323 and the second telescopic member 333 respectively drive the first flipping frame 320 and the second flipping frame 330 to rotate, ensuring the stability of the rotation, improving the rotation effect, preventing the situation that the upper die 110 is stuck, and improving the flipping quality.

[0049] As a further technical solution, the first flipping frame 320 is provided with an avoidance groove 324 for avoiding the second flipping frame 330.

[0050] In this embodiment, after the first flipping frame 320 drives the upper die 110 to complete the flipping, the upper die 110 is sent to the position of the second flipping frame 330 for continuous flipping. The avoidance groove 324 is used to avoid the second flipping frame 330 to prevent the first flipping frame 320 and the second flipping frame 330 from colliding. The design of the avoidance groove 324 shortens the distance between the first flipping frame 320 and the second flipping frame 330, shortens the time interval between the two flips, and improves the flipping speed and efficiency.

[0051] As a further technical solution, the heights of one ends of the first flipping frame 320 and the second flipping frame 330 are higher than the avoidance space 220.

[0052] In this embodiment, the height of one end of the first flipping frame 320 and the second flipping frame 330 is higher than that of the avoidance space 220. When the upper mold 110 is moved to the first flipping frame 320 by the conveyor belt 210, it will be blocked by the end of the first flipping frame 320 that is higher than the avoidance space 220, preventing the upper mold 110 from continuing to move along the conveyor belt 210, and then being flipped by the flipping frame. Through this design, the flipping frame can control the flipping time, thereby controlling the working efficiency of the device.

[0053] As a further technical solution, the end of the second flipping frame 330 that is higher than the avoidance space 220 is provided with a receiving plate 334, and the receiving plate 334 is used to receive and protect the upper mold 110.

[0054] In this embodiment, after the second flipping frame 330 is flipped, the opening of the upper mold 110 faces downward. Therefore, a receiving plate 334 is designed at the part of the second flipping frame 330 that contacts the upper mold 110, ensuring that there is a certain support for the sand mold of the upper mold 110 during the flipping process, preventing the sand mold of the upper mold 110 from being damaged due to collision or small vibration, and ensuring the safety of the device during operation.

[0055] As a further technical solution, it further includes: a mold clamping frame 4 is slidably arranged at one end of the conveyor belt 210. After the mold clamping frame slides, it approaches or moves away from the conveyor belt 210; a carrier vehicle 5 is used to carry the lower mold 120; a clamping frame 420 is arranged on the mold clamping frame 4 in a lifting manner. After the clamping frame 420 is lifted, it approaches or moves away from the carrier vehicle 5, and the clamping frame 420 is used to clamp the upper mold 110 and dock with the lower mold 120.

[0056] In this embodiment, during the conveying process of the upper mold 110 by the conveyor belt 210, it will be flipped 180° as a whole by the first flipping frame 320 and the second flipping frame 330, so that the opening faces downward. After continuing to be conveyed and reaching the mold clamping frame, the clamping member will descend, fix the lower mold 120 to the mold clamping frame and clamp it up. The mold clamping frame drives the upper mold 110 to leave the conveyor belt 210 by sliding. After the mold clamping frame moves to the designated position, the clamping frame 420 will descend, enabling the upper mold 110 to complete the docking of the upper and lower molds 120 with the carrier vehicle 5 and complete the mold clamping operation. Through the design of the mold clamping frame and the clamping frame 420, the accuracy of the mold clamping operation is improved, and the efficiency of the mold clamping operation is improved. The design of the carrier vehicle 5 enables the upper and lower molds 120 to be directly transported away for pouring in the next process after the mold clamping operation, ensuring the continuity of production and preventing the molds from accumulating at one position.

[0057] As a further technical solution, it further includes: a third telescopic member 430 is arranged on the mold clamping frame 4. The third telescopic member 430 has a third telescopic end 431, and the third telescopic end 431 is connected to the clamping frame 420. The third telescopic member 430 is used to drive the clamping frame 420 to lift.

[0058] In this embodiment, the third telescopic member 430 is an oil cylinder, and it can also be a cylinder or an electric oil cylinder or other components that can achieve the same function. Through the design of the third telescopic member 430, the stability of the lifting of the upper die 110 driven by the clamping frame 420 is ensured, preventing the sand mold in the upper die 110 from being broken due to factors such as collision and vibration, and ensuring the integrity of production.

[0059] As a further technical solution, it further includes: There are several positioning heads 440, which are rotatably arranged on the clamping frame 420. A clamping space 441 is formed between the several positioning heads 440, and the clamping space 441 is used to clamp the upper die 110.

[0060] In this embodiment, the positioning head 440 has grooves, and these grooves can directly clamp the positioning sleeve of the upper die 110. Through the swinging of the positioning head 440, the upper die 110 can be firmly clamped, effectively preventing the upper die 110 from falling and ensuring the accuracy of mold closing.

[0061] As a further technical solution, it further includes: There are several fourth telescopic members 450, which are arranged on the clamping frame 420. The fourth telescopic member 450 has a fourth telescopic end 451, and the fourth telescopic end 451 is connected to the pressure head 452. The fourth telescopic member 450 is used to press the upper die 110 while the clamping frame 420 is lifted and lowered.

[0062] In this embodiment, multiple fourth telescopic members 450 can ensure the stable lifting and lowering of the clamping frame 420. The fourth telescopic member 450 is used to press the upper die 110 while the clamping frame 420 is lifted and lowered, preventing the upper die 110 from rotating.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
