Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, and relates to an injection mold for a wall-mounted trash can. Background Technology

[0002] Injection molds are devices used to produce plastic products. Plastic raw materials are heated to a molten state and then injected into the molding cavity inside the mold. After the molding cavity is filled, the mold is rapidly cooled, and the molten plastic raw materials cool and solidify to form the desired plastic parts. Using injection molds to produce plastic products has advantages such as high precision and high efficiency.

[0003] Trash cans are products made of plastic, and therefore can be produced using injection molding. To make trash cans more convenient to use, wall-mounted trash cans exist in the existing technology. These trash cans have a hook structure that allows them to be hung on the wall. To improve the connection strength between the hook and the trash can, the hook can be integrally formed on the trash can during the production process. Therefore, it is necessary to improve the molding cavity structure inside the injection mold. Summary of the Invention

[0004] The purpose of this utility model is to address the problems existing in the current technology by proposing an injection mold for a wall-mounted trash can. The technical problem to be solved by this utility model is: how to optimize the internal structure of the injection mold.

[0005] The purpose of this utility model can be achieved through the following technical solution: An injection mold for a wall-mounted trash can includes a top plate, a fixed template fixed to the bottom of the top plate, a movable template slidably connected to the bottom of the fixed template, and several upwardly protruding molding blocks on the top of the movable template. Each molding block can be enclosed with the bottom of the fixed template to form a sealed molding cavity. A bucket body that has been cooled and molded is provided inside the molding cavity. A molding groove connected to the molding cavity is provided at the bottom of the fixed template. The opening of the molding groove is downward. A hook integrally connected to the bucket body is provided inside the molding groove.

[0006] In this design, molten plastic heated to a molten state is injected into the molding cavity, which fills the cavity and the connected molding groove. After the mold cools down, the molten plastic cools and forms the body structure of the trash can. Hooks that are integrally connected to the body are formed inside the molding groove. By setting up a structure with multiple molding blocks, multiple molding cavities can be formed inside the mold. Multiple trash can products can be manufactured in one production process, improving production efficiency. Furthermore, by setting the molding groove downwards, the hooks formed inside the molding groove can be more easily separated from the fixed mold during the separation of the fixed mold and the moving mold, making it less likely to stick and facilitating demolding.

[0007] In the injection mold of the aforementioned wall-mounted trash can, the bottom of the fixed mold plate is provided with several longitudinally arranged connecting grooves. The height of the connecting grooves is flush with the molding groove. The two sides of the connecting grooves are connected to the molding groove and the molding cavity, respectively. Reinforcing ribs, formed by cooling, are provided inside the connecting grooves. These reinforcing ribs are integrally connected to the hook and the can body. The reinforcing ribs are used to improve the structural strength of the hook and increase its service life. The flush height of the connecting grooves with the molding groove facilitates the complete filling of the molding groove by the molten metal.

[0008] In the injection mold of the aforementioned wall-mounted trash can, the moving mold plate is equipped with a slidingly connected push plate, which is arranged around the periphery of the molding block and located at the bottom of the molding cavity. By placing the push plate at the bottom of the molding cavity, it moves upward during demolding, applying pushing force at various positions on the bottom of the can body, thereby preventing the can body from deforming during ejection.

[0009] In the injection mold of the aforementioned wall-mounted trash can, the four corners of the fixed template, push plate, and moving template are respectively provided with longitudinally connected guide holes. Guide posts are installed inside the guide holes, and the fixed template and push plate are slidably connected to the guide posts. The guide posts serve a guiding function, allowing the push plate and fixed template to move longitudinally along the direction of the guide posts.

[0010] In the injection mold of the aforementioned wall-mounted trash can, the bottom of the moving template has a through hole that extends to the bottom of the push plate. This through hole structure allows a top column to extend from the bottom of the moving template, pushing the push plate upwards and separating the can body from the molding block.

[0011] In the injection mold of the aforementioned wall-mounted trash can, the bottom of the fixed mold plate is provided with a positioning slope, and a wear-resistant block is fixedly attached to the positioning slope. The wear-resistant block can abut against the side wall at the top of the moving mold plate. During the mold closing process of the fixed mold plate and the moving mold plate, the wear-resistant block abuts against the side wall at the top of the moving mold plate to prevent displacement when the fixed mold plate and the moving mold plate are closed.

[0012] In the injection mold of the aforementioned wall-mounted trash can, the top plate is provided with a feed inlet, and the bottom of the feed inlet is provided with a connected flow divider plate. The bottom of the flow divider plate is provided with several connected nozzles, and the bottom of each nozzle is connected to the molding cavity. Molten plastic heated to a molten state is injected through the feed inlet. After being diverted by the flow divider plate, the molten liquid flows evenly into the nozzles at the bottom and is finally injected into the molding cavity.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. In this solution, the molten plastic can be cooled to form the body structure of the trash can, and hooks that are integrally connected to the body can be formed inside the molding tank. The molding tank is set downwards, and during the separation of the fixed mold and the moving mold, the hooks formed inside the molding tank can be more easily separated from the fixed mold, are less likely to stick, and are easy to demold.
