Box foaming mold of refrigerator freezing chamber

Abstract

The invention discloses a box foaming mold of a refrigerator freezing chamber. The box foaming mold of the refrigerator freezing chamber comprises a freezing box foaming mold, and is characterized in that a slide block is arranged on the right side wall of the freezing box foaming mold; a connecting bar is arranged on the side wall of the slide block; the lower end of the connecting bar is connected through a cylinder; a box freezing water receiving tank is arranged at the top of a freezing box; the inner wall of the top of the freezing box is hinged with an overturning base; the lower end of the overturning base is hinged with a push rod; a cylinder is arranged below the push rod; the push rod is slidingly mounted in a freezing movable frame; the left end side wall of the freezing movable frame is hinged with a guide bar; and the guide bar is hinged with a box freezing left end splicing block. The box foaming mold of the refrigerator freezing chamber is high in box demolding efficiency, simple in internal cylinder structure and excellent in foaming molding tightness.

Description

technical field [0001] The invention relates to a foaming mold for a refrigerator, in particular to a foaming mold for a freezer compartment of a refrigerator. Background technique [0002] In the existing container for refrigeration, the insulation of the box body is realized by foaming in the wall cavity of the box with polyurethane. When foaming, in order to prevent the inner and outer box wall boards from being bulged under the force, it needs to be clamped with inner and outer fixtures, but there is no inner fixture for foaming at present. The method used is to use steel plates on the ground in the container. The upper welding support frame is used to temporarily withstand the inner box wall of the container. It is very troublesome to weld the support frame every time it is foamed, and then remove it for the next welding and foaming. The level of automation determines the level of development of the manufacturing industry. With the continuous improvement of people's li...

Problems solved by technology

Most of the existing refrigerator liner production lines are produced by a large number of workers with some simple automation equipment. However, at this stage, the wages of workers are constantly increasing, and the corresponding labor costs of production enterprises are getting higher and higher, which is not conducive to the development of enterprises. development and competition; in addition, when workers are tired, they are prone to misuse and hurt themselves, resulting in work-related injuries, which brings potential risks to the enterprise; and through manual production, there is no fixed technical standard, the product quality is unstable, and production low efficiency
