Description

Technical Field

[0001] The invention belongs to the technical field of refrigerator door lining molding, and in particular relates to a refrigerator door lining molding die. Background Art

[0002] An ice door lining is usually provided on the inner surface of the refrigerator door. In order to prevent cold air from leaking out of the refrigerator's refrigeration space, the door lining has a slot for installing a door seal so that a circle of door seal can be installed on the inner surface of the refrigerator door. The door seal is a plastic material with embedded magnets. When the refrigerator door is closed, the door lining is clamped between the door and the metal frame of the cabinet, and the refrigerator is kept sealed through the adsorption force between the magnets and the metal frame.

[0003] The existing door lining forming mold has a single-turn structure, such as Figures 1 to 3 As shown, the door lining forming mold includes a mold body 500 and a demoulding slider 200 located on the outer peripheral side of the mold body 500. A guide fixing seat 300 is provided below the demoulding slider 200. The demoulding slider 200 matches the outer peripheral contour of a portion of the card slot 100. After the door lining is formed, the door lining moves upward under the action of an external force. There are matching inclined surfaces between the guide fixing seat 300 and the demoulding slider 200. The inclined surfaces are inclined upward away from the mold body 500, and the door lining drives the demoulding slider 200 to move upward; the guide fixing seat 300 The demoulding slider 200 is fixedly connected with the demoulding slider 200 by a limit screw 400 to limit the rising height of the demoulding slider 200. When the demoulding slider 200 rises to the specified height, the demoulding slider 200 is completely separated from the slot 100, and the demoulding slider 200 falls back to the initial position due to its own gravity. The demoulding slider 200, the guide fixing seat 300 and the limit screw 400 form a single-flip structure. However, the portion of the slot 100 close to the mold body 500 does not have a single-flip structure. Under the action of external force, the refrigerator door lining is separated from the mold body 500, causing the refrigerator door lining to warp and deform, and the slot 100 cannot be adapted to the door seal, affecting the sealing of the refrigerator.

[0004] In view of this, the present invention is proposed. Summary of the invention

The outer panel 9 can be flipped to abut against the side of the limiting plate 3 close to the mold body 2. The inner panel 6 and the outer panel 9 are arranged opposite to each other. The overall shape of the inner panel 6 and the outer panel 9 matches the groove contour, so that when the refrigerator door lining is demoulded, the external force drives the refrigerator door lining to move upward, and the outward-turning slider 8 drives the outer panel 9 to flip toward the limiting plate 3.

[0055] like Figure 4 As shown, in this embodiment, the limit plate 3, the inner block 6 and the outer block 9 extend in the same direction in the horizontal direction, and the limit plate 3, the inner block 6 and the outer block 9 are all in the shape of long strips, and the inner block 6 and the outer block 9 are clamped and fixed between the inward-turned base 4 and the outward-turned base 7.

[0056] like Figures 5 to 10 As shown, in this embodiment, at least two first support arms 41 extending upward are provided on the inward-turning base 4, and the upper ends of the first support arms 41 and the inward-turning slider 5 are respectively provided with through holes for the first rotating shaft 42 to pass through so that the inward-turning slider 5 is clamped between the two first support arms 41.

[0057] like Figures 5 to 10As shown, in this embodiment, two first support arms 41 are arranged in sequence along the extension direction of the inner insert 6, the first rotation axis 42 is arranged along the extension direction of the inner insert 6, and the inward sliding block 5 drives the inner insert 6 to rotate around the first rotation axis 42.
