Problems solved by technology

However, this kind of mold has the following disadvantages: when demoulding, the upwardly moving module is very easy to forcibly take out the sealed groove part that has been formed but has not been cooled and finalized, causing the sealed groove part to be strained, scratched, or even caused The door liner of the refrigerator is partially deformed, which affects the final quality of the product

Embodiment

[0021] Example: Combine figure 1 , figure 2 with image 3 Shown is a specific embodiment of the refrigerator door gall sealing groove forming mold of the present invention, which is installed as an insert in the socket 12 around the body 1 of the refrigerator door gall plastic mold body 1, and includes two oppositely flipped buckles. Forming the turning bar 3 of the groove forming cavity 2 and at least one power device for driving the two turning bars 3 to move. This power device is composed of a driving element 4 and a transmission mechanism connecting the driving element 4 and the two turning bars. .

[0022] In this embodiment, both ends of each turning bar 3 are pinned in the slot 12 through a cylindrical pin 13, and at the same time, a mounting plate 14 located below the two turning bars 3 is fixed in the slot 12, and the driving element 4 is fixed on the slot 12. On the mounting plate 14, it includes an output head 5 that can be stretched up and down; and the transmi...

Abstract

The invention discloses a forming die for refrigerator door-liner sealing grooves, which is arranged on a refrigerator door-liner adsorption plastic die body as an insert. The forming die comprises two turnover strips which can be oppositely turned over and buckled to form a sealing-groove forming cavity, as well as at least one power device which drives the motion of the two turnover strips, wherein the power device consists of a driving element and a transmission mechanism connected with the driving element and the two turnover strips. As the structure of the forming die for refrigerator door-liner sealing grooves adopts the design of the movable-type turnover strips, the two turnover strips are driven to be oppositely turned over through the power device in a demolding process, so as to allow a sealing groove on a refrigerator door liner to fall off. Compared with the prior sealing-groove forming die adopting the design of pieced-type modules, the demolding process of the forming die has the advantages of better safety and stability, can particularly not pull or scratch the sealing groove of the refrigerator door liner, and can effectively prevent the local deformation of the refrigerator door liner.

Description

technical field [0001] The invention relates to a mold for forming a refrigerator door gall sealing groove. Background technique [0002] The existing refrigerator door liner is usually made by blister molding process. The body of the blister mold used in this processing technology is surrounded by special sealing molds to form the four sides of the refrigerator door liner for installation. Four sealing grooves for the sealing strip. [0003] Since the cross-sectional profile of the sealing groove is usually narrow at the notch and wide inside the groove, in order to facilitate its smooth demoulding after forming, the existing sealing groove forming mold adopts the structure of two modules that are combined with each other Form; each module is equipped with a half molding cavity, and when the molding cavities on the two modules are joined together, a complete molding cavity that is consistent with the cross-sectional profile of the sealing groove to be processed is formed. ...
