Description

Technical Field

[0001] The utility model relates to the technical field of material assembly, in particular to a feeding device. Background Art

[0002] Metal insert injection molding is a method of pre-fixing metal inserts at appropriate positions in a mold, then injecting plastic to form, and after opening the mold, the inserts are tightly wrapped by the cooled and solidified plastic and buried in the product to obtain injection molded products with inserts such as threaded rings and electrodes. The combination of the insulating property of plastic and the conductive property of metal can well meet the requirements of the electrical safety performance of the product. At the same time, the easy formability of plastic and the rigid characteristics of metal not only provide new possibilities for the flexibility of product design, but also can effectively avoid complicated secondary processes such as hot melting, welding and riveting, effectively shortening the assembly time and cost. Therefore, metal insert injection molding is widely used in various industries such as electrical appliances, automobiles, medical treatment, electronic products and connectors.

[0003] Limited by the mold structure and the accuracy of the robot, most of the insert injection moldings in the industry adopt the method of manually placing inserts. However, this method has the following problems: 1) The temperature of the inner mold of the injection mold is as high as 200 - 300 °C. When reaching into the inner mold to place the inserts, there is a very high safety risk of scalding the employee's hand; 2) Small inserts are difficult to pick up. The insert holes reserved in the mold are small and delicate, and manual errors such as misalignment, dropping, and improper installation are likely to occur during the installation of inserts; 3) The light in the injection molding machine is not good. On-site, employees need to hold a flashlight sideways to illuminate the space inside the machine to find the insert holes and at the same time confirm the placement effect of the inserts. This makes the injection molding cycle long and the injection efficiency low, and even leads to the scrapping of injection molded products.

[0004] For example, the front shell components of the power supplies of most switch power supplies and household electrical appliances in the company are injection molded from PC plastic raw materials and metal electrode sheet inserts. The specification of the electrode sheet as an insert is only 20mm * 6.25mm * 1.5mm, and the temperature of the inner mold is above 270 °C. The design of a four-cavity mold for one injection requires manual placement of at least 8 small inserts into the injection inner mold at a high temperature of 270 °C for at least 60 s at a time. Working in a harsh environment for a long time continuously not only makes the reliability of the product unable to be guaranteed, but also is extremely prone to safety hazards.

[0005] Therefore, it is necessary to develop a high-efficiency auxiliary feeding device for small metal insert injection molding. Content of the Utility Model

Then hold the armrest 17 of the feeding device tightly. Here, the material of the armrest 17 is preferably plastic wrapped with aluminum alloy to make it lighter. Lift the feeding device in a reclined manner, align the positioning post 9 on the feeding device with the positioning hole 15 on the mold 3, and gently push to complete the precise positioning, which is labor-saving and smooth. At this time, apply a slight force to the armrest 17 to compress the elastic member 16 sleeved on the positioning post 9, so that the movable part 7 slowly approaches the fixed part 1, and drive the ejector pin 2 through the movable part 7 to eject the insert 5, then the insert 5 in the hole of the insert 5 can be smoothly sent into the mounting hole 6 of the high-temperature mold 3 of the injection molding machine. After all the inserts 5 are sent into the mounting hole 6 of the mold 3, stop applying force to the armrest 17, and the movable part 7 of the feeding device will automatically rebound to the original position through the elastic member 16. Take out the feeding device easily, and then the next round of operation can be started.

[0077] On one side of the fixed part 1 of this embodiment close to the mold 3, a plurality of feeding holes 4 are provided, and inserts 5 are arranged in the plurality of feeding holes 4. The ejector pin 2 is inserted into the feeding hole 4 from the side of the fixed part 1 away from the mold 3, the ejector pin 2 abuts against the insert 5, and the ejector pin 2 is used to push the insert 5 into the mounting hole 6 of the mold 3. The feeding device can be directly placed on the normal temperature workbench, then insert the insert 5 into the feeding hole 4 of the feeding device, then pick up the feeding device, align the positioning post 9 of the feeding device with the positioning hole 15 in the high-temperature mold 3 and insert it, to complete the precise matching of the feeding device and the mold 3. Then press the movable part 7 through the armrest 17 to make the movable part 7 press down and approach the fixed part 1. Through the guiding action of the positioning post 9 fixed on the fixed part 1 and the linear bearing 11 fixed on the movable part 7, and synchronously adjusted through the elastic member 16 sleeved on the positioning post 9, easy pressing can be achieved, and the insert 5 can be automatically and smoothly pushed into the mounting hole 6 of the mold 3, avoiding problems such as laboriousness and jamming. With the help of the feeding device, not only the potential safety hazard that employees may be scalded during high-temperature operation is effectively avoided, but also the installation of a number of inserts 5 can be completed with one key, greatly improving the feeding efficiency and accuracy.

[0078] Unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present application. In all examples shown and discussed herein, any specific values should be construed as merely exemplary and not as limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

[0079] It should be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be oriented "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device may also be otherwise oriented (rotated 90 degrees or at other orientations), and the spatially relative descriptions used herein should be interpreted accordingly.

[0080] In addition, it should be noted that the use of terms such as "first" and "second" to define components is merely for the convenience of differentiating the corresponding components. Without further statement, these terms have no special meaning and thus should not be construed as limiting the scope of protection of the present application.

[0081] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
