The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, a refrigerator door foaming apparatus with a middle mold mechanism is used for foaming and molding a foaming layer of a refrigerator door, and comprises a liftable upper mold mechanism 1 arranged on a frame 9, a liftable lower mold mechanism 2 and a middle mold mechanism 3. The frame 9 includes four columns 91, a top platform 92 disposed on top ends of the four columns, and a bottom platform 93 disposed on bottom ends of the four columns.

The upper die mechanism 1 includes a foaming tank 11 and an accessory provided on the foaming tank 11 to assist foaming. The accessory for assisting in foaming on the foaming box 11 is not within the scope of the present invention, and the detailed description thereof is omitted. The foaming tank 11 is set on the top base 92 by an upper mold lifting mechanism 401. Specifically, the upper die lifting mechanism 401 is provided on the top base 92, and the foam box 11 is provided below the top base 92 by the upper die lifting mechanism 401 and can be lifted and lowered by the driving of the upper die lifting mechanism 401.

The lower mold mechanism 2, referring to fig. 2, 3, and 4, includes a lower mold base 21 and a base crane 22. The base crane 22 is provided on the base plate 93 via a lower mold lifting mechanism 402, and can be lifted and lowered by the lower mold lifting mechanism 402. The lower mold base 21 is arranged on the base lifting frame 22 and is used for arranging the mold 29.

The upper die mechanism 1 and the lower die mechanism 2 are arranged oppositely up and down. Specifically, the lower die mechanism 2 is located below the upper die mechanism 1. The foaming tank 11 is open at the bottom. When the upper die mechanism 1 and the lower die mechanism 2 are lifted and lowered to close the dies by driving the upper die lifting mechanism 401 and the lower die lifting mechanism 402, respectively, the bottom opening of the foam box 11 is sealed by the lower die base 21, and the die 29 provided on the lower die base 21 is sealed in the foam box 11.

In this embodiment, the upper die lifting mechanism 401 and the lower die lifting mechanism 402 both adopt a motor gear tooth column mechanism 4. The motor gear column mechanism 4 includes a motor 41, a gear box 42, and a column 43. A gear meshed with the tooth column 43 is arranged in the gear box 42; the gears in the gear box 42 are connected with the motor 41 through a transmission mechanism. The transmission mechanism here includes a speed reducer and a transmission shaft. The motor 41 is connected to the middle section of the transmission shaft, and the gear boxes 42 are arranged at the ends of the transmission shaft, so that the motor 41 is correspondingly connected with the two gear boxes 42. The upper die lifting mechanism 401 and the lower die lifting mechanism 402 each include two motor gear post mechanisms 4. Specifically, each motor gear column mechanism 4 includes one motor 41, two gear boxes 42, and two columns 43. The upper mold lifting mechanism 401 and the lower mold lifting mechanism 402 respectively include two motors 41, four gear boxes 42, and four tooth columns 43. Specifically, in the upper mold lifting mechanism 401, the motor 41 and the gear box 42 are fixedly arranged on the top table 92, and the bottom of the tooth column 43 is connected with the foaming box 11. Specifically, in the lower mold lifting mechanism 402, the motor 41 and the gear box 42 are fixedly provided on the base lifting frame 22. The tooth post 43 is vertically disposed on the base plate 93.

The middle mold mechanism 3 is a mechanism provided between the upper mold mechanism 1 and the lower mold mechanism 2, and includes a sealing frame 31, a mold clamping power mechanism 32, and a lifting frame 33. The sealing frame 31 and the lifting frame 33 are all four-sided frame structures. The seal frame 31 is provided on the lifting frame 33 by a frame locking mechanism 34. The lifting frame 33 is provided on the frame 9 via the mold clamping power mechanism 32 and the lifting rail mechanism 35. Specifically, the lift rail mechanisms 35 are provided on the columns 91, and one lift rail mechanism 35 is provided for each column 91. The four corners of the elevating frame 33 pass over the elevating guide mechanism 35 and can move up and down along the elevating guide mechanism 35. The mold clamping power mechanism 32 employs four cylinders. The four cylinders are respectively positioned at four corners of the lifting frame 33. Thus, the lifting frame 33 can be driven by four cylinders to be lifted.

The middle mold mechanism 3 is used for assisting in mold closing between the upper mold mechanism 1 and the lower mold mechanism 2. When the upper die mechanism 1 and the lower die mechanism 2 are closed, the upper die mechanism 1 and the lower die mechanism 2 are respectively closed with the middle die mechanism 3, so that the upper die mechanism 1 and the lower die mechanism 2 are connected in a sealing mode. The specific mold closing process is as follows: when the die is closed, the foaming box 11 moves downwards under the drive of the upper die lifting mechanism 401, and the lower die base 21 drives the die 29 to lift upwards under the drive of the lower die lifting mechanism 402; when the foaming box 11 moves to the mold closing position, the sealing frame 31 in the middle mold mechanism 3 moves upwards under the driving of the air cylinder to be in butt joint with the bottom opening of the foaming box 11, so that the mold closing is completed, and then the lower mold base 21 with the mold 29 continuously ascends until the mold closing is completed in butt joint with the sealing frame 31.

Further, the upper die mechanism 1, the lower die mechanism 2, and the middle die mechanism 3 can be precisely butted at the time of mold clamping. In this embodiment, referring to fig. 5, a guide post 18 is provided on the foaming tank 11. There are four guide posts 18. The lifting base 22 is provided with four guide holes 28 corresponding to the four guide posts 18. When the upper and

lower die mechanisms

1 and 2 are clamped together, the guide posts 18 can be inserted into their corresponding guide holes 28.

In addition, it should be noted that the "frame" in the lifting frame and the sealing frame referred to in the present specification is a hollow frame structure inside the quadrilateral entity.
