[0002] Injection molds are essential tools for producing plastic products. They typically consist of a cavity, core, gating system, cooling system, and demolding mechanism. Their working principle involves injecting molten plastic material under high pressure into the mold cavity using an injection molding machine. After cooling and solidification, the molded plastic product is obtained. Injection molds offer advantages such as high precision, high efficiency, and repeatable production. They are widely used in various fields, including automotive parts manufacturing (e.g., bumpers, dashboards), electronics (e.g., housings, connectors), and daily necessities (e.g., plastic basins, cups, toothbrush handles). For example, in automotive manufacturing, injection molds can produce complex-shaped and precisely sized interior parts, such as door handles, ensuring both aesthetic appeal and meeting strength and durability requirements.

[0003] When processing car glove boxes, molds are used for injection molding. Traditional molds make it difficult to remove the molded material after injection molding, requiring workers to use tools to remove it. Furthermore, the inability to move the mold after injection molding makes it difficult to quickly clean the residue inside, which brings inconvenience to the processing of car glove boxes and increases the limitations of injection mold usage.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model involves using an electric telescopic rod to move the upper mold downwards during the injection molding of a car glove box until it contacts the lower mold. Injection is then performed through the injection port. After injection, the electric telescopic rod moves the upper mold upwards to separate it from the lower mold. The drive motor then rotates the transmission column 90 degrees, which in turn rotates the rotating disk 90 degrees. The rotating disk rotates the lower mold 90 degrees. Multiple lower molds are mounted on the top of the rotating disk. After the lower mold is removed, the empty lower mold rotates to the bottom of the upper mold, allowing injection to continue. When the material moves to the inclined fixing block, it is pressed against the inclined contact block, causing the inclined contact block to move upward. The inclined contact block drives the ejector rod to move upward, while simultaneously driving the return spring to press upward. The ejector rod moves upward, causing the ejector plate and sliding block to move upward along the limiting slide groove. The ejector plate drives the formed car glove box to move upward to the top of the upper mold, where it can be quickly removed. After removal, it can be quickly cleaned before continuing injection molding, thus providing the advantage of easy injection molding. Through the coordinated use of the drive component, rotating component, and return ejector component, the material can be quickly removed and cleaned, and the use of the injection mold is not limited.

[0014] 2. By setting a driving component, this utility model can drive the rotating component to rotate, effectively avoiding the situation where the rotating component cannot rotate during use, and effectively improving the ease of use of the rotating component. Attached Figure Description
