Description

Technical Field

[0001] This utility model relates to the field of refrigerator manufacturing technology, specifically to a foaming device for refrigerator manufacturing. Background Technology

[0002] In the refrigerator manufacturing process, rust-proof aluminum sheets are generally used to form an outer frame, which serves as the refrigerator's outer shell, through pressing, punching, and splicing. Plastic panels are then placed inside the outer frame to form the refrigerator's inner liner. Foaming liquid is injected between the outer frame and the plastic panels to connect them and maintain a constant internal temperature. While insulating the refrigerator's interior, the foaming liquid also provides support. During the foaming process, the outer shell and inner liner need to be placed in a foaming mold for auxiliary positioning.

[0003] Most existing refrigerator manufacturing foaming equipment uses screws to connect and fix the foaming device and the mold. When foaming different sizes of outer shell and inner liner, different sizes of molds need to be replaced, which is inconvenient to disassemble and reduces processing efficiency to some extent. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or existing foaming devices for refrigerator production, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a foaming device for refrigerator production. During use, multiple clamping frames are placed in a sliding groove and pushed until one side of each clamping frame is respectively in contact with the upper and lower mold bases. Under the action of a drive motor, the first lead screw rotates, causing the third fixing plate to descend along the second guide post. Simultaneously, under the action of a first transmission belt, the rotating shaft rotates. Under the action of a second transmission belt, the third pulley drives the second lead screw to rotate, causing the second fixing plate to rise along the first guide post. The second and third fixing plates simultaneously limit the multiple third bosses, causing the multiple second bosses to clamp the multiple first bosses respectively, thus raising the upper mold base. The mold base and lower mold base are fixed, and then the outer shell is placed inside the lower mold base. The inner liner is secured in the limiting block of the upper mold base by the flexible properties of the inner plastic material. The foaming liquid is poured into the outer shell, and the mold closing assembly is used for foaming. When it is necessary to change the mold to a different size, the drive motor is started to release the clamping frame, which makes it easy to replace the upper and lower mold bases. This solves the problem that most existing refrigerator production foaming devices are connected and fixed to the foaming device and mold by screws. When it is necessary to foam the outer shell and inner liner of different sizes, it is necessary to change the mold of different sizes, which is inconvenient to disassemble and reduces the processing efficiency to a certain extent.
