Description

The refrigerator doors liner

The utility model relates to a kind of refrigerator doors liner.

On the inside door of refrigerator, often be equipped with the magazine of a plurality of grooveds, for the storing of various beverage or other food Bottle ﹠ Can; Traditionally, the common employing of magazine is embedded in the liner metal plate spare of door removably; As shown in Figure 1, establish a pair of draw-in groove 10 about usually on the liner metal plate spare 1 of door, and the both end sides of magazine 2 is established the convex clip tenon 20 relative with draw-in groove 10, by this convex clip tenon 20 embed draw-in grooves 10 just, magazine 2 can be attached on the surface of liner metal plate spare 1 in embedding.

It is one-body molded that the liner metal plate spare 1 of refrigerator is adopted the foaming mode usually, therefore, any rill on its surface, concavo-convex also must be in foaming process, form by the one step foaming that helps of mould.As above-mentioned draw-in groove 10 on liner metal plate spare 1, its post 11 that fastens in the outer end is a continuous long column, this common must the beginning by the auxiliary fixture more than two successfully of foaming that fastens post 11, reason is that main mould 30 needs to withdraw from (as shown in Figure 2) from the surface of liner metal plate spare 1 after forming liner metal plate spare 1, but owing to fastening stopping of post 11 of continuous shape, make the mould that forms draw-in groove 10 parts to withdraw from, so that can't produce this liner metal plate spare 1 with the mould of whole group integral type; As shown in Figure 2, the formation of this draw-in groove 10 must place the predetermined fixed-site that forms draw-in groove 10 earlier with another less auxiliary fixture 31 before foaming, and then insert main mould 30, withdraw from main mould 30 and auxiliary fixture 31 and follow the reverse order of inserting behind its foaming again; Because not only one of the draw-in groove 10 on the door lining metal plate spare 1 of general refrigerator, and all be and be symmetrical arranged, therefore, auxiliary fixture 31 amounts required when foaming are also not within minority, usually cause the surge of mould development cost; In addition, auxiliary fixture 31 general volumes are less, be again movable design, and it settles the location to cooperate other detent mechanism auxiliary usually again, and are so unusual complicated and cost is not low; Moreover the mould tool of this complexity has also must be with more working experience in the operation.

At the shortcoming that prior art exists, the purpose of this utility model is to provide a kind of refrigerator doors liner, but the mat unitary mould is come the inner lining structure of foaming, and this structure refers to it is as the structure that fastens of supporting the post magazine in the liner metal plate spare especially; This fastens post is to form the projection shape to arrange, and each projection spacing each other is to decide according to the dilation of foaming.

For achieving the above object, the utility model is achieved through the following technical solutions: a kind of refrigerator doors liner, refer in particular to the post that fastens in the structure of fastening that is embedded usefulness as magazine; It is characterized in that: this fastens post and is the interrupted projection row of arranging.

Fastening post is to be made of equidistant arrangement of the projection more than two.

The spacing that fastens the projection of post depends on the foaming and intumescing degree of this inner lining structure.

By the utility model refrigerator doors liner, overcome the shortcoming of prior art, reached the purpose of above-mentioned creation, pass through the utility model, when the protruding pin that forms bump pitch is set on main mould, and its post that fastens that extends through formation is in the future arrived to the draw-in groove place, actual desire forms the draw-in groove place and does not then establish the auxiliary for tool of relative shape; The purpose of this kind way expands outwardly expansion when general foaming degree is to predict, when promptly can ad infinitum not expanding after certain expansion again; Therefore, originally convexedly stretched in the protruding pin of following draw-in groove formation place, and, and made herein foaming under the effect that does not need with relative shape tool, still can form one draw-in groove even discontinuous form but can effectively suppress the infinite extension of foaming; The most successful is, the protruding pin of facilitating draw-in groove to form is still all rightly deviate from from fastening the dwelling with its formed projection row with main mould; So, can the foaming that other auxiliary fixtures just can be finished draw-in groove be needn't establish in addition, the development cost of mould and the structure of simplification mould effectively reduced; Moreover, change over the interrupted post that projection is listed as with fastening post by continuous integral post, at all not influencing it provides being embedded of magazine; In this, the post that fastens that is the projection row that the utility model provides has the high economic benefit that promotes industry development in fact.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Fig. 1 is the structure graph that is embedded of known refrigerator magazine;

Fig. 2 is the foaming application drawing that structure is utilized mould that is embedded of known refrigerator magazine;

Fig. 3 is the utility model refrigerator lining metal plate spare partial structurtes and mould part-structure figure thereof;

Fig. 4, the 5th, the operative relationship figure of the utility model liner metal plate spare and mould, wherein Fig. 4 is that vertical view, Fig. 5 are front view.

As Fig. 3, Fig. 4 and shown in Figure 5, the utility model refrigerator doors liner be serve as a contrast within it on the metal plate spare 4 form one be the projection row fasten post 40, itself and 41 of the projections on liner metal plate spare 4 form a draw-in groove 42 that can be embedded for the magazine (not shown) of refrigerator.The formation of above-mentioned liner metal plate spare 4, especially refer to the moulding at draw-in groove 42 places, be can be with a unitary mould 5, form many on the one end and be equidistant protruding pin 50, this protruding pin 50 protrude out length after this unitary mould 5 is inserted the location, can pass and fasten post 40, and draw-in groove 42 and be butted on projection 41 surfaces after the moulding; The function of this protruding pin 50 is except that forming the fastening the post 40 of projection row, because it is the precalculated position that equidistantly convexedly stretches in draw-in groove 42 after the moulding, so the swelling in foaming process will be limited by these protruding pin 50, make unlikely being filled up of draw-in groove 42 book offices and whole formation one draw-in groove 42 that causes by foaming; This practice is to calculate the dilation of foaming and the spacing that determines protruding pin 50, even if make that it need not one as traditional elongated auxiliary fixture 31, also can form identical shaped draw-in groove 42 by the interrupted protruding pin of arranging 50.Above-mentioned protruding pin 50 on unitary mould 5 be except that can helping to form the draw-in groove 42, its in addition nature will fasten post 40 and form equidistant projection and arrange, so fasten after post 40 also can be beneficial to foaming, unitary mould 5 can directly break away from from liner metal plate spare 4 surfaces; It is plural layout that the number of this projection is looked the length that fastens post 40.

In sum, general refrigerator is fastened post as what magazine was embedded, make discrete projection row into according to the foaming and intumescing degree and fasten post, it not only can reach the moulding of draw-in groove, and hold concurrently can be with foaming molding mold integral body, simplification, significantly reduces production costs and simplifies processing procedure.
