Technical Field

[0001] This utility model relates to the field of plug injection molding technology, specifically to a plug injection mold. Background Technology

[0002] Currently, power cord plugs are injection molded using a pre-embedded method. The injection mold for this process needs to be designed with the plug model in mind, with one mold per product. Multiple products require multiple molds. When multiple products are injection molded on the same machine, the entire mold set needs to be changed, but the high development cost of the molds leads to high production costs. Utility Model Content

[0003] The purpose of this invention is to design a plug injection mold that allows one mold to be used for multiple products, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A plug injection mold is provided, comprising an upper mold and a lower mold. The upper mold has an upper mounting groove, in which an upper inner mold core is installed. The upper inner mold core has multiple upper cavities. The lower mold has a lower mounting groove, in which a lower inner mold core is installed. The lower inner mold core has lower cavities that correspond one-to-one with the upper cavities. The upper cavities and the lower cavities are fitted together after mold closing to form a mold cavity. The upper inner mold core and the lower inner mold core are respectively mounted on the upper mounting groove and the lower mounting groove by fixing members.

[0006] Furthermore, the fixing component is an embedded screw, and the upper inner mold core and the lower inner mold core are respectively installed on the upper mounting groove and the lower mounting groove by the embedded screw.

[0007] Furthermore, it also includes a plug auxiliary limiting strip, on which multiple plugs to be injected are mounted, and the multiple plugs to be injected are matched with the mold cavity; both the upper inner mold core and the lower inner mold core are provided with fixing grooves for placing the plug auxiliary limiting strip.

[0008] Furthermore, the plug auxiliary limiting strip has multiple insert slots, and the inserts of the plug to be injection molded can be embedded in the insert slots.

[0009] Furthermore, the lower inner mold core is provided with multiple wiring grooves, which cooperate with the mold cavity.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] When using this invention, if a product needs to be replaced for injection molding, the upper inner mold core and the lower inner mold core are removed from the upper mounting slot and the lower mounting slot, respectively. Then, the upper inner mold core and the lower inner mold core corresponding to the product are replaced and installed on the upper mounting slot and the lower mounting slot respectively by fasteners. The product can be molded in the replaced mold cavity, thus realizing one mold for multiple products and reducing the mold development cost. Attached Figure Description

[0016] 1. Upper mold; 2. Lower mold; 3. Upper mounting slot; 4. Lower mounting slot; 5. Upper inner mold core; 6. Lower inner mold core; 7. Lower cavity; 8. Plug auxiliary limiting strip; 9. Fixing slot; 10. Insert slot; 11. Cable tray slot. Detailed Implementation

[0017] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0018] Example: Please refer to Figure 1-2A plug injection mold includes an upper mold 1 and a lower mold 2. The upper mold 1 has an upper mounting groove 3, in which an upper inner mold core 5 is installed. The upper inner mold core 5 has multiple upper cavities. The lower mold 2 has a lower mounting groove 4, in which a lower inner mold core 6 is installed. The lower inner mold core 6 has lower cavities 7 that correspond one-to-one with the upper cavities. After the upper cavities and lower cavities 7 are closed, they cooperate to form a mold cavity. The upper inner mold core 5 and the lower inner mold core 6 are respectively installed on the upper mounting groove 3 and the lower mounting groove 4 by fixing members. The fixing members are embedded screws. The upper inner mold core 5 and the lower inner mold core 6 are respectively installed on the upper mounting groove 3 and the lower mounting groove 4 by embedded screws, which facilitates the disassembly and installation of the upper inner mold core 5 and the lower inner mold core 6, allowing one mold to be used for injection molding of multiple products. Multiple cable trays 11 are provided on the lower inner mold core 6. The cable trays 11 cooperate with the mold cavity, and the power cords of the plug can be inserted into the cable trays 11 one by one to prevent the power cords from being misaligned during the injection molding process.

[0019] It also includes a plug auxiliary limiting strip 8, on which multiple plugs to be injected are mounted, and these plugs match the mold cavity. Both the upper inner mold core 5 and the lower inner mold core 6 have fixing grooves 9 for placing the plug auxiliary limiting strip 8. The plug auxiliary limiting strip 8 has multiple insert slots 10, into which the inserts of the plugs to be injected can be embedded. Before injection molding, the inserts of the plugs to be injected are inserted into the insert slots 10 on the plug auxiliary limiting strip 8 to initially fix the plugs. Then, the plug auxiliary limiting strip 8 is placed directly into the fixing grooves 9 for injection molding. All the injection-molded products are removed from the lower cavity 7 together via the plug auxiliary limiting strip 8, allowing for convenient and quick removal without the need for pulling or tugging. This ensures more stable removal, prevents damage to the plugs, and greatly guarantees the quality of the injection-molded product.

[0020] The working principle of this embodiment is as follows: When it is necessary to change the product for injection molding, the upper inner mold core 5 and the lower inner mold core 6 are removed from the upper mounting slot 3 and the lower mounting slot 4 respectively by the embedded screws. Then, the upper inner mold core 5 and the lower inner mold core 6 of the corresponding product and the plug auxiliary limiting strip 8 are replaced and installed on the upper mounting slot 3 and the lower mounting slot 4 respectively by the embedded screws. The prongs of the plug to be injected are inserted into the prong slot 10 on the corresponding plug auxiliary limiting strip 8. The plug auxiliary limiting strip 8 is placed in the fixing slot 9. The power cord of the plug is inserted into the cable tray 11 for limiting. Finally, the injection molding is performed.

[0021] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "upper," "lower," "left," "right," "front," "back," and similar expressions used in this document are for illustrative purposes only.

[0022] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
