Description

Technical Field

[0001] The utility model relates to the technical field of molds, and particularly relates to an injection mold for a front camera bracket. Background Technique

[0002] A mold is various dies and tools used in industrial production to obtain required products by methods such as injection molding, blow molding, extrusion, die casting, or forging and stamping, smelting, stamping, etc. In short, a mold is a tool for making formed articles. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the surface of articles through the change of the physical state of the formed material and is known as the "mother of industry". An injection mold is a tool for producing plastic products. Generally, an injection mold consists of a front mold and a rear mold. When injection molding, the front mold and the rear mold are closed to form a runner system and a cavity for the plastic product. During injection molding, the mold is clamped on an injection molding machine, molten plastic is injected into the cavity, and it cools and forms in the cavity. At the same time, the molten plastic also cools into runner system condensate in the runner system. After the plastic product is formed, the front mold and the rear mold are separated, and the plastic product is ejected from the cavity by the ejection system and leaves the mold. Finally, the front mold and the rear mold are closed again for the next injection molding, and the entire injection molding process is carried out cyclically.

[0003] In the application of injection molds, generally, a front mold insert is used to help the injection mold shape more complex and delicate structures on the product, such as special textures, grooves, or protrusions. As Figure 1 shown, a plastic product of a front camera bracket has protrusion-like structures on its surface; and when the front mold insert is worn or damaged, the front mold insert can be replaced separately without having to replace the entire mold, reducing costs; however, due to the usually complex shape of the front mold insert, it is difficult to ensure its fitting accuracy with other parts of the mold during the assembly process, which may lead to assembly errors and affect the quality of the injection-molded product.
