Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold for a charging connector housing. Background Technology

[0002] Injection molds are tools used to produce plastic products, and they also give plastic products a complete structure and precise dimensions. Injection molding is a processing method used to mass-produce certain complex-shaped parts. Specifically, it refers to injecting heated and molten plastic into the mold cavity under high pressure by an injection molding machine, and then obtaining the molded product after cooling and solidification.

[0003] Depending on the product being molded, the mold will have different injection cavities; however, some products have upward and / or downward convex sidewalls. Figure 8 Furthermore, the wall thickness of this sidewall is very thin (e.g., a charging connector shell). In this case, it is necessary to carve a groove corresponding to the sidewall of this type of product into the cavity of the upper mold core and / or lower mold core. However, since the size of this groove needs to correspond to the wall thickness of the sidewall, the size of the groove is too small, which makes it extremely inconvenient to process the groove and makes it impossible to ensure the accuracy of the groove, resulting in poor product molding quality. Therefore, it is urgent to design a new injection mold to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a charging connector shell injection mold with a simple and reasonable structure, convenient manufacturing, and guaranteed product quality.

The moving mold has a moving mold core embedded in it, and the moving mold core has a moving mold cavity. The moving mold core includes a mold core body and a fitting plate. The fitting plate is installed on the mold core body and is connected to the mold core body for limiting. A convex wall groove is formed between the fitting plate and the mold core body. The fixed mold has a fixed mold core embedded in it, and the fixed mold core has a fixed mold cavity corresponding to the moving mold cavity. The core-pulling unit is located on one side of the fixed mold. When the moving mold and the fixed mold are closed, the core-pulling unit will be inserted between the moving mold core and the fixed mold core, and cooperate with the moving mold cavity and the fixed mold cavity to form an injection cavity.

When the fitting plate is inserted into the mounting hole, the first shaped concave surface and the second shaped concave surface cooperate to form a convex wall groove.

[0009] In one embodiment, the core-pulling unit includes a fixed base, a driving component, and a mandrel. The fixed base is connected to one side of the fixed mold, the driving component is installed on the outside of the fixed base, and the mandrel is connected to the driving component. The driving component can drive the mandrel to move between the moving mold core and the fixed mold core, so that it cooperates with the moving mold cavity and the fixed mold cavity to form an injection molding cavity.

[0010] In one embodiment, the moving mold is connected to a moving template, and the moving template is provided with an injection port communicating with the injection cavity.

[0011] In one embodiment, the fixed mold is connected to a fixed template, and the fixed template has fixed mold feet. Both sides of the fixed template are connected to the fixed mold through the fixed mold feet.

[0012] In one embodiment, a demolding top plate is provided between the fixed mold and the fixed template. The demolding top plate is located between the fixed mold feet on both sides, and a plurality of demolding pins are provided on the demolding top plate, with the top of the demolding pins located in the fixed mold cavity.
