Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of molds, in particular to a sliding insert structure. Background Art
[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the surface processing of objects by changing the physical state of the molded material, and is known as the "mother of industry". Injection molds are tools for producing plastic products. Generally, injection molds are composed of an upper mold and a lower mold. During injection molding, the upper mold and the lower mold are closed to form a runner system and a mold cavity for plastic products. During injection molding, the mold is clamped on the injection molding machine, and the molten plastic is injected into the mold cavity and cooled and formed in the mold cavity. At the same time, the molten plastic is also cooled in the runner system to form a runner system condensate. After the plastic product is formed, the upper mold and the lower mold are separated, and the plastic product is ejected from the mold cavity through the ejection system and leaves the mold. Finally, the upper mold and the lower mold are closed again for the next injection molding. The entire injection molding process is carried out in a cycle.
[0003] Slide inserts are important parts of the mold. They are inserted into the inner cavity from both sides of the mold to change the inner cavity structure, thereby producing injection molded parts with corresponding structures. Due to the different structures of the injection molded parts, the shapes of the corresponding slide inserts are also different.
[0004] like Figure 1 As shown, a surface of the product needs to form multiple hole structures, and the depths of the multiple holes are different, which can be specifically divided into through holes and non-through blind holes (or through holes of different depths or blind holes of different depths). In the prior art, the holes mentioned above are generally formed by a slide driving a slide insert, and slide inserts of different lengths are designed to correspond to hole structures of different depths. During the normal mold opening process of the mold, since these slide inserts of different lengths are generally driven by the same slide, synchronous withdrawal action can be achieved. However, this also causes some problems, especially the slide inserts with slightly shorter lengths will be separated from the product first than the slide inserts with slightly longer lengths. This makes it easy for the holes with slightly shallower depths to be deformed by the corresponding traction force due to the separation from the strength support of the corresponding slide inserts, accompanied by the withdrawal action of the holes with slightly deeper depths and the slide inserts thereon.
[0005] Therefore, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content

[0014] The top ends of the first row insert and the second row insert are flush with the end surface of the boss and are limitedly matched with the second groove.
[0015] As a further solution of the utility model: a plurality of the first channels are provided along the length direction of the first step structure, and the plurality of first channels are evenly arranged;
[0016] A plurality of the second channels are arranged along the length direction of the second step structure, and the plurality of second channels are evenly arranged;
