Description

Technical Field

[0001] The present application relates to the technical field of molds, and in particular to a small-size opening adapter shell molding mold and a molding process. Background Art

[0002] The power adapter is a small and portable power supply conversion device for electronic devices and electronic appliances. It is generally composed of components such as a casing, a transformer, an inductor, a capacitor, a control IC, and a PCB board. Its working principle is to convert AC input into DC output. It can be divided into wall-mounted and desktop types according to the connection method. It is widely used in security cameras, set-top boxes, routers, light strips, massagers and other equipment.

[0003] In the process of manufacturing the adapter shell, in order to meet the needs of installing parts such as power cords and metal sockets, it is necessary to open some smaller holes on the surface of the shell. The design of these holes is crucial to the overall function and appearance of the adapter. The current common practice is to first form the basic shape of the adapter shell through a mold, and then open corresponding small-sized mounting holes on the surface of the shell through subsequent processing steps such as drilling or punching. Although this method can achieve the required functions, the production process is relatively complicated and requires additional processing steps to open the mounting holes, which not only increases production costs, but also affects production efficiency. In addition, errors may occur during the drilling or punching process, resulting in inaccurate position or size of the mounting holes, thereby affecting production quality. This problem needs to be solved urgently. Summary of the invention

[0004] In order to reduce the production cost of a small-size opening adapter shell and improve production efficiency and production quality, the present application provides a small-size opening adapter shell forming mold and a forming process.

When the upper template and the lower template are molded together, the two movable mold bases move synchronously in a direction close to the fixed mold base, and the fixed mold base, the two movable mold bases, the upper mold core and the lower mold core together form a molding cavity for the adapter shell. When the upper template and the lower template are separated from the mold, the two movable mold bases move in a direction away from the fixed mold base. The upper template is provided with a glue injection tube for injecting molten plastic into the molding cavity, the glue injection tube penetrates into the fixed mold base and is connected with the molding cavity, and the glue injection tube fixed sleeve is provided with an insert for molding the small-size opening of the adapter shell.

[0006] By adopting the above technical scheme, the upper template supports the upper mold core, and the lower template supports the lower mold core. When the upper template and the lower template are molded, the two movable mold bases move synchronously in the direction close to the fixed mold base, and the fixed mold base, the two movable mold bases, the upper mold core and the lower mold core together form a molding cavity for the adapter shell. At the same time, the insert enters the molding cavity, and the glue injection tube injects glue into the molding cavity for injection molding operation. The glue injection tube penetrates into the fixed mold base and is connected with the molding cavity, so that the water outlet position is located inside the adapter shell after molding and is hidden. When the injection molding operation is completed, the upper template and the lower template are separated, and the two movable mold bases move in the direction away from the fixed mold base, and the end of the glue injection tube is also pulled out from the fixed mold base. At this time, the molded adapter shell is sleeved on the fixed mold base. The staff only needs to take the adapter shell out of the fixed mold base to complete the blanking operation. The small-size opening adapter shell is formed at one time, and no subsequent hole opening steps are required, which reduces the process flow, thereby reducing the production cost of the small-size opening adapter shell, and is conducive to improving production efficiency and production quality.

[0007] Preferably, the mouth of the injection tube is horn-shaped, and after passing through the fixed mold base, the mouth of the injection tube is connected with the molding cavity through the side wall of the fixed mold base, and the mouth of the injection tube is flush with the side wall of the fixed mold base.

[0008] By adopting the above technical solution, this arrangement enables the sprue position of the adapter shell after molding to be located on the inner wall of the adapter shell and hidden, and there is no need to perform subsequent grinding operations on the sprue position. This reduces the process steps without affecting the appearance of the adapter shell, which is beneficial to improving production efficiency and production quality.

[0009] Preferably, the upper mold plate is provided with a driving member, and during the process of closing the upper mold plate with the lower mold plate, the driving member drives the movable mold base to move toward the direction approaching the fixed mold base.

[0010] By adopting the above technical solution, during the process of closing the upper mold plate and the lower mold plate, the driving member drives the movable mold base to move toward the direction close to the fixed mold base, and the upper mold core and the lower mold core move toward each other, so that the fixed mold base, two movable mold bases, the upper mold core and the lower mold core are combined to form a molding cavity, and the setting of the movable mold base facilitates subsequent material unloading operations.

[0011] Preferably, the driving member is configured as a driving block, the driving block is located at one side of the upper mold core and fixedly connected to the upper mold plate, and the driving block is wedge-shapedly matched with an end of the movable mold base facing away from the fixed mold base.

[0012] By adopting the above technical solution, when the upper mold plate and the lower mold plate are closed, the driving block moves toward the direction close to the movable mold base. When the driving block abuts against the movable mold base, the driving block and the end of the movable mold base facing away from the fixed mold base are wedge-shaped and can push the movable mold base to move toward the direction close to the fixed mold base, thereby realizing the movement of the movable mold base.

[0013] Preferably, a reinforcing rod is fixedly provided at the bottom of the driving block, the reinforcing rod is inclined, and the movable mold base is correspondingly provided with a through hole. When the upper mold and the lower mold are separated, the lower end of the reinforcing rod is aligned with the through hole in the vertical direction.

[0014] By adopting the above technical solution, the driving block drives the reinforcing rod to move synchronously. After the reinforcing rod passes through the through hole, it pushes the movable mold base to move toward the fixed mold base, which is beneficial to improving the convenience of the movable mold base when moving toward the fixed mold base.

[0015] Preferably, the lower mold core is fixedly provided with a guide column, and the movable mold base is sleeved and slidably mounted on the guide column.

[0016] By adopting the above technical solution, the movable mold base is sleeved and slidably moved on the guide pillars, and the guide pillars guide the movement of the movable mold base, which is beneficial to improving the stability of the movable mold base when moving.

When the molding operation of the adapter shell is completed, the upper mold plate and the lower mold plate are separated, and the restoring force of the reset spring pushes the movable mold base to move away from the fixed mold base to facilitate the unloading operation of the adapter shell after molding.

[0020] By adopting the above technical solution, the external cooling water channel surrounds the circumference of the molding cavity to cool the molding process, which is beneficial to improving the molding efficiency.

At the same time, the two movable mold bases move away from the fixed mold base. The molded adapter shell is sleeved on the fixed mold base, and the staff takes the molded adapter shell out of the fixed mold base.

[0024] By adopting the above technical solution, when it is necessary to produce an adapter shell with a small opening, the upper template and the lower template are molded together, and the driving block pushes the movable mold base to move in the direction close to the fixed mold base, so that the fixed mold base, the two movable mold bases, the upper mold core and the lower mold core are surrounded to form a molding cavity. The injection tube passes through the fixed mold base and then injects glue into the molding cavity. The insert molds a small opening of the adapter shell, and the plastic in the molding cavity is cooled by the internal cooling water channel and the external cooling water channel to mold an adapter shell with a small opening. Then the upper template and the lower template are separated from the mold, and the molded adapter shell is put on the fixed mold base. The staff can take the molded adapter shell out of the fixed mold base. The molded adapter shell has a small opening and does not require subsequent hole opening steps, which reduces the process flow, thereby reducing the production cost of the small-size opening adapter shell and is conducive to improving production efficiency and production quality. In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting a fixed mold base, two movable mold bases and an insert, and the injection tube penetrates into the fixed mold base and is connected with the molding cavity, when the upper mold plate and the lower mold plate are molded, the two movable mold bases move synchronously in the direction close to the fixed mold base, and the fixed mold base, the two movable mold bases, the upper mold core and the lower mold core are surrounded to form a molding cavity of the adapter shell.

The injection tube penetrates into the fixed mold base and is connected with the molding cavity, so that the water inlet position is located at the adapter shell after molding. The adapter shell is hidden inside. When the injection molding operation is completed, the upper template and the lower template are separated, and the two movable mold bases move away from the fixed mold base. The end of the injection tube is also pulled out from the fixed mold base. At this time, the molded adapter shell is sleeved on the fixed mold base. The staff only needs to take the adapter shell out of the fixed mold base to complete the blanking operation. The small-size opening adapter shell is formed at one time and does not require subsequent hole opening steps, which reduces the process flow, thereby reducing the production cost of the small-size opening adapter shell and is conducive to improving production efficiency and production quality.

[0025] 2. By setting the nozzle of the injection tube in a horn shape, the nozzle position of the adapter shell after molding is located on the inner wall of the adapter shell and hidden, and there is no need to grind the nozzle position subsequently. The process steps are reduced without affecting the appearance of the adapter shell, which is conducive to improving production efficiency and production quality.

[0026] 3. By setting a driving block, when the upper mold plate and the lower mold plate are closed, the driving block moves toward the direction close to the movable mold base. When the driving block abuts against the movable mold base, the driving block and the end of the movable mold base away from the fixed mold base are wedge-shaped and can push the movable mold base to move toward the direction close to the fixed mold base, so as to realize the movement of the movable mold base, thereby cooperating with the fixed mold base, the upper mold core and the lower mold core to form a molding cavity.
