Over-the-wall forming mould of inner liner of refrigerator door

Abstract

The invention discloses an over-the-wall forming mould of an inner liner of a refrigerator door. The over-the-wall forming mould comprises a mould containing cavity arranged in an inner liner plastics suction mould body of the refrigerator door, an over-the-wall forming mould body which is vertically arranged is arranged in the mould containing cavity, the upper end part of the over-the-wall forming mould body extends out of the mould containing cavity, the over-the-wall forming mould body is hinged on the inner liner plastics suction mould body of the refrigerator door through a rotating shaft in an inwards-outwards overturn manner, an overturning mechanism used for driving the over-the-wall forming mould body to inwards and outwards overturn is arranged below the rotating shaft, an emptying gap is remained between the outer side surface of the over-the-wall forming mould body and the cavity wall of the mould containing cavity, and an outwards-overturning angle positioning mechanism used for limiting the outwards-overturning angle of the over-the-wall forming mould body is arranged below the rotating shaft. The over-the-wall forming mould of the inner liner of the refrigerator door is capable of forming inner liners with different sizes, very convenient to operate, and capable of improving the production efficiency of the inner liners of the refrigerator doors with different specifications.

Description

technical field [0001] The invention relates to the field of production and manufacture of refrigerators, in particular to a forming mold for wall-mounting of refrigerator doors. Background technique [0002] There are generally several small hanging walls integrated with the refrigerator door on the door liner of the refrigerator. These hanging walls are used to connect the article bracket and the door liner body. Put cola, eggs and other refrigerated items in the item bracket on the top. [0003] Existing refrigerator door liner is usually made by blister molding process, and the plastic-absorbing mold body adopted in this processing technology is all provided with special wall-hanging forming molds to form the wall-hanging wall on the refrigerator door liner. [0004] The structure of the existing refrigerator door liner wall-hanging forming mold can also refer to figure 1 As shown, it generally includes a mold cavity 2 provided in the main body 1 of the refrigerator do...

AI Technical Summary

Problems solved by technology

[0005] Since the outer surface of the wall forming mold body 3 abuts against the cavity wall of the cavity 2 during each molding, the horizontal dimension at which the upper end of the wall forming mold body 3 is exposed outside the cavity 2 is always a fixed value. , such as 9.5mm, you can only form a certain fixed size (9.5mm) of the door liner wall, if you want to use this refrigerator door liner wall forming mold to form a door of 10.5mm or 8.5mm and other sizes If the inner wall is hung on the wall, it is necessary to widen or narrow the upper end of the wall forming mold body 3. The processing procedure is very cumbersome and reduces the production efficiency of the door inner wall of the refrigerator.
