Detailed Description

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

As shown in fig. 1, 2 and 3, the refrigerator door foaming box with the sealing gasket frame is provided. The foaming box comprises a box body 1, a locking mechanism 2 and a sealing cushion frame 3. The box body 1 is enclosed by four wall plates 19 and a top plate at the top, and the bottom is open. The four sides of the bottom opening of the box body 1 are surrounded by a plate frame to form a locking mechanism mounting surface 11. The locking mechanism 2 is provided on the locking mechanism mounting surface 11. In this embodiment, four sides of the box 1 are respectively provided with one locking mechanism 2, and the total number of the locking mechanisms 2 is four. The sealing cushion frame 3 is arranged at the bottom opening of the box body 1 through four locking mechanisms 2 arranged on the locking mechanism mounting surface 11. Here, the sealing gasket frame 3 is also a sealing frame in the background art.

The locking mechanism 2, referring to fig. 5 and 6, includes a cylinder 21, a plurality of locking pendulums 22, a mounting bar 23 and a driving bar 24. The cylinder 21, the locking pendulum 22 and the driving bar 24 are all arranged on the mounting bar 23. The mounting bar 23 and the driving bar 24 are both elongated bodies. The driving bar 24 is disposed on one side of the mounting bar 23 through a plurality of locking members 232 and is parallel to the mounting bar 23. The cylinder 21 is arranged on the mounting bar 23 through a bracket, is positioned on the same side of the mounting bar 23 as the driving bar 24 and is connected with the driving bar 24. The telescopic direction of the piston rod of the air cylinder 21 is parallel to the mounting strip 23. Thus, the driving bar 24 can be moved back and forth along the longitudinal direction of the mounting bar 23 on one side of the mounting bar 23 by the driving of the air cylinder 21. The mounting bar 23 is provided with a flat hole 231. The opening of one end of the flat hole 231 is located at one side where the driving bar 24 is disposed, and the opening of the other end is located at the opposite side of the one side where the driving bar 24 is disposed. The locking pendulum 22 includes a gear portion 221 and a locking portion 222 connected to each other. The gear portion 221 has an arc-shaped edge, and engaging teeth are provided on the edge. A swing shaft 223 is provided at the center of the gear portion 221. The latching portion 222 is a portion in which the edge of the gear portion 221 protrudes outward. The locking pendulum 22 is disposed in the flat hole 231 of the mounting bar 23 via a swing shaft 223, and can swing in the flat hole 231 about the swing shaft 223. As the locking pendulum 22 swings, the locking portion 222 can extend out of the flat hole 231 or retract into the flat hole 231. The driving bar 24 is provided with a rack 241. The driving bar 24 is connected to the locking pendulum 22 through the meshing relationship of the rack gear 241 and the gear portion 221. Thus, when the driving rod 24 is driven by the cylinder 21 to move back and forth, the locking pendulum 22 is driven to swing around the swing shaft 223 by the meshing relationship between the rack gear 241 and the gear portion 221, so as to drive the locking portion 222 to either protrude out of the flat hole 231 or retract into the flat hole 231. When the locking portion 222 extends out of the flat hole 231, the locking portion 222 can lock the sealing cushion frame 3 at the bottom opening of the box 1.

In this embodiment, the opening sealing frame 3 includes a support frame 31 and a cushion frame 32. The support frame 31 is made of a hard metal material, such as stainless steel or aluminum alloy; the cushion frame 32 is made of an elastic material such as rubber or other elastic resin. The cushion frame 32 is provided on the support frame 31. The support frame 31 is larger than the four sides of the cushion frame 32, but is thinner than the cushion frame 32, so that the support frame 31 has locking portions 311 protruding outward from the four sides of the cushion frame 32 at the four sides, and the cushion frame 32 protrudes from both upper and lower surfaces of the support frame 31. The upward protruding part of the cushion frame 32 is used for sealing with the bottom opening of the box body 1; the cushion frame 32 has a downwardly projecting portion for sealing when the lower mold is closed. The cushion frame 32 protrudes downward, so that a stepped structure is formed between the cushion frame 32 and the locking portion 311. When the locking portion 222 locks the sealing gasket frame 3 at the bottom opening of the box body 1, the locking portion 222 is locked to the locking portion 311, and specifically, the locking portion 222 and the locking mechanism mounting surface 11 hold the locking portion 311.

In addition, in order to improve the sealing effect between the opening sealing gasket frame 3 and the box body 1 and to facilitate the assembly and installation, in the present embodiment, referring to fig. 3 and 4, a stepped groove 111 is provided inside the locking mechanism mounting surface 11. When the locking portion 222 locks the sealing gasket frame 3 at the bottom opening of the box body 1, the edges of the four sides of the supporting frame 31 are clamped in the stepped groove 111.

Further, the refrigerator door foaming box in the embodiment can be configured to produce two refrigerator door foaming boxes simultaneously. For this purpose compartment ribs 12 are provided in the housing 1. The compartment rib 12 is positioned on the central axis of the box body 1 and divides the box body 1 into two symmetrical halves at the left side and the right side. Corresponding to the compartment ribs 12, referring to fig. 7, the sealing cushion frame 3 may be further provided with partitions 33. The partition 33 is vertically arranged on the supporting frame 31, and the edge is provided with a cushion strip 331 and a plurality of limit blocks 332. The cushion strips 331 are made of an elastic material. The stoppers 332 are disposed on two sides of the edge of the partition 33, and the stoppers 332 on the two sides of the edge of the partition 33 are disposed opposite to each other. Therefore, when the sealing cushion frame 3 is arranged at the bottom opening of the box body 1 through the locking mechanism 2, the partition plate 33 is in butt joint with the partition chamber rib 12, so that the space in the box body 1 is divided into two parts to form two foaming chambers, and the two foaming chambers are stacked left and right. At this time, the stoppers 332 on both sides of the edge of the partition 33 are held by the cell rib 12, and the partition 33 is pressed against the cell rib 12 by the cushion strip 331. Thus, the sealing between the two foaming chambers is achieved by the cushion strips 331 between the partition 33 and the cell ribs 12.

In addition, it should be noted that the "frame" in the plate frame, the sealing cushion frame, the support frame and the cushion frame referred to in the specification is a hollow frame structure inside the quadrilateral solid.

It should be noted that in the locking mechanism 2 of the present embodiment, the driving bar 24 is provided with a plurality of racks 241 corresponding to the locking pendulums 22. Those skilled in the art will appreciate that the racks 241 on the driver blade 24 may be integrally formed, or the driver blade 24 may itself be a rack.
