Embodiment Construction
[0012] In the following, the specific implementation manners of the present invention will be further described in detail in conjunction with the accompanying drawings of the embodiments, so as to make the technical solution of the present invention easier to understand and grasp.
[0013] In view of the complex structure and performance requirements of the aforementioned refrigerator drawer slide assembly, the present invention specifically proposes an injection molding mold for the slide plate of the refrigerator drawer slide assembly, which solves the problems of smooth sliding of the slide assembly and smooth ejection of the product. Such as figure 1 As shown, the slide plate 3 is a square body with a width greater than that of the base rail and is provided with a socket groove 31 which is fitted with a convex rib on the slide assembly base rail. 32.
[0014] Such as figure 2 with image 3 As shown, the injection molding mold of the slide plate of this kind of refriger...

The invention discloses an injection mould for a sliding plate of a sliding rail assembly of a refrigerator drawer. The sliding rail assembly is formed by assembling a foundation rail, a sliding plate and an interconnected guide member, wherein the sliding plate is a square sheet body wider than the foundation rail and is provided with a sleeved groove of a convex rib for slidably connecting and assembling the foundation rail; and the side, vertical to the sleeved groove, of the sliding plate, extends in a bending way and is provided with a pair of convex teeth. Particularly, the injection mould corresponding to the sliding plate is composed of an upper mould and a lower mould, wherein the sleeved groove is used as a mould opening plane of the upper mould and the lower mould; the upper mould is provided with a first mold cavity for a sectioning part of the appearance corresponding to the sliding plate along one half of the sleeved groove, and one side of the first mold cavity is provided with a telescopic block for correspondingly forming the convex teeth; and the lower mould is provided with a second mold cavity for a sectioning part of the appearance corresponding to the sliding plate along the other half of the sleeved groove. By using the injection mould disclosed by the invention, the demolding efficiency of injection molded finished products is increased, and the demolding fault condition generated because a product is complex in structure and is clamped together with the mold cavity is avoided. The precision of the product is effectively improved, the yield is effectively increased, and the sliding rail assembly can slide conveniently and smoothly.
Description
technical field [0001] The invention relates to a mold design, in particular to an injection molding mold for a slide plate of a refrigerator drawer slide rail assembly. Background technique [0002] Refrigerators are one of the necessary household appliances for ordinary people. With the continuous development of refrigerator functions and structural design, multi-door refrigerators with side-by-side doors combined with lower drawers currently occupy the mainstream of the market. As refrigerator drawer components, in order to improve its Pull to open, push to close the product durability, smoothness and cost optimization, using hard plastic to make the slide rail assembly and apply it to the refrigerator drawer assembly is an ideal technical solution. Moreover, the use of the slide rail assembly can effectively reduce the overall weight of this type of refrigerator, and also reduce the difficulty of product logistics. [0003] The slide rail assembly is usually assembled f...
