Abstract

The invention discloses a door stopper and door seal unsealing groove demolding mechanism. The mechanism comprises a bottom plate, wherein four lifting lugs are fixed to the top surface of the bottom plate and distributed on the top surface of the bottom plate in a rectangular shape; an outer mold body is fixed to the middle of the top surface of the bottom plate; an inner mold body is arranged in the outer mold body; a demolding assembly is arranged at the joint of the outer mold body and the inner mold body, and the demolding assembly comprises a mounting strip; the mounting strip is fixed to the inner side wall of the outer mold body; a door seal inner side part and a door seal outer side part are fixed to the joint of the inner mold body and the outer mold body separately; and the demolding assembly is used for demolding a refrigerator and freezer door liner door sealing groove structure. The door stopper and door seal unsealing groove demolding mechanism is reasonable in design, door stopper and door seal demolding is convenient and fast, and door stopper and door seal parts are evenly stressed during demolding, therefore, the damage rate of a door plate during demolding is well reduced; and in addition, the mechanism is good in sealing performance, and few defect spots exist on the inner wall of an unsealing groove after demolding, therefore, a certain guarantee is provided for subsequent convenient door stopper and door seal processing.

Description

technical field [0001] The invention relates to the technical field of refrigerator processing auxiliary equipment, in particular to a door suction and door seal release groove release mechanism. Background technique [0002] Refrigerator door liner is usually made by blister molding process. The body of the plastic mold used in this processing technology is surrounded by special sealing molds to form the four sides of the refrigerator door liner to install the sealing strip. There are four sealing grooves, which increases the difficulty of releasing the refrigerator door from the mold, so the research on the release of the door suction and door seal release groove is particularly important. [0003] After searching, the patent application number 200910114830.6 discloses a refrigerator door gall sealing mold, which is installed on the refrigerator door blister mold body as an insert; The turning bar and at least one power device for driving the two turning bars are composed...
