The refrigerator door generally comprises an outer shell, an inner shell and a foaming layer which is arranged between the outer shell and the inner shell and is used as an inner container. Wherein, the foaming layer is used for refrigerator heat preservation. Before the outer shell, the inner shell and the foaming layer form the refrigerator door body, the foaming layer needs to be foamed into the shape of the refrigerator door body through the refrigerator door body foaming equipment according to the shape set by the die so as to be convenient for later installation.

In the prior art, a plurality of foaming devices for refrigerator door bodies exist. Among them, there is a common one in which the foam molding is performed after the upper mold and the lower mold are closed. In such a refrigerator door foaming apparatus, the upper mold generally includes a foaming box body with an open bottom, and the lower mold includes a mold table and a mold disposed on the mold table. And a foaming closed space is formed between the upper die and the lower die after the die assembly. After the upper die and the lower die are assembled, the die table of the lower die closes the bottom opening of the box body, and the die on the die table is closed in the box body. In order to realize the sealing between the upper die and the lower die, a sealing frame is required to be arranged at the bottom opening of the foaming box body.

On the other hand, the foaming box body is large in size due to the fact that the refrigerator door body needs to be contained, and the foaming box body is matched with a component arranged on the foaming box body through a foaming process, so that the manufacturing cost of the foaming box body is high. In modern society, various refrigerators have different sizes due to large personalized demands. In order to save the cost of the refrigerator production line, each refrigerator production line needs to be capable of producing various models of products. Particularly in the foaming production of the refrigerator door liner, one foaming box needs to be used for producing various types of refrigerator door liners. In order to match with the moulds with different sizes on the mould table, the sealing frame arranged at the opening at the bottom of the foaming box needs to be synchronously adjusted.

Detailed Description

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

As shown in fig. 2, the refrigerator door foaming box with sealing gasket cascade comprises a box 901, a sealing gasket cascade frame 902 and a sealing frame 903. The box 901 is enclosed by four wall panels and a top panel at the top, and is open at the bottom. Four sides of the bottom opening of the case 901 are respectively provided with a sealing locking mechanism 904. The sealing gasket cascade frame 902 is arranged at the bottom opening of the box body 901 through a sealing locking mechanism 904. The sealing frame 903 is disposed at the bottom opening of the case 901 through a sealing gasket cascade frame 902.

The sealing gasket cascade frame 902, referring to fig. 1, includes a plate frame 1 and a locking mechanism 2. The plate frame 1 is a frame body surrounded by four laths 11. The locking mechanism 2, which is arranged on the lath 11 and is shown in fig. 3 and 4, comprises 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 driver blade 24 is disposed on one side of the mounting blade 23 by a plurality of detents 232 and is parallel to the mounting blade 23. The air cylinder 21 is arranged on the mounting strip 23, is positioned on the same side of the mounting strip 23 as the driving strip 24 and is connected with the driving strip 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 lock 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.

When the sealing locking mechanism 904 locks the sealing gasket cascade frame 902 at the bottom opening of the box 901, the sealing locking mechanism 904 acts on the plate frame 1 of the sealing gasket cascade frame 902. The locking mechanism 2 is used for locking the sealing frame 903, so that the sealing frame 903 and the sealing pad cascade frame 902 are fixed. Specifically, the sealing frame 3 is fixed to the gasket cascade frame 902 by a locking mechanism 2 provided on the gasket cascade frame 902. In this embodiment, the structure of the sealing and locking mechanism 904 is similar to that of the locking mechanism 2 in this embodiment, and the specific structure thereof may refer to the locking mechanism 2, which is not described in detail.

To reduce the width of the locking mechanism 2, it is avoided that the locking mechanism 2 on the panel frame 1 interferes with the sealing locking mechanism 904 to lock the panel frame 1. In the present embodiment, the air cylinder 21 and the mounting bar 23 are linearly arranged. Specifically, that is, the cylinder 21 and the mounting bar 23 are coaxially arranged such that the cylinder 21 and the mounting bar 23 are in a straight line. At this time, the mounting bar 23 and the cylinder 21 are fixed to each other by their ends, and in order to equalize the stress of the driving bar 24, the locking mechanism 2 includes two mounting bars 23 in this embodiment. Both mounting bars 23 are provided with at least one flat hole 231, and are provided with corresponding locking pendulums 22 through the flat holes 231. The cylinder 21 is disposed between two mounting bars 23 and fixed to one of the mounting bars 23.

In the present embodiment, in order to facilitate the sealing gasket cascade frame 902 to lock the sealing frame 903, referring to fig. 1 and 5, a stepped groove 111 is provided on one inner surface of the plate frame 1. The other side is provided with a soft cushion frame 12. Thus, when sealing gasket cascade frame 902 locks sealing frame 903, sealing frame 903 is caught in step groove 111 on the inner side of plate frame 1. The cushion frame 12 is located on the side where the plate frame 1 is connected with the edge of the bottom opening of the box 901, and is used for sealing between the sealing cushion cascade frame 902 and the box 901.
