Description

Technical Field

[0001] The utility model relates to the technical field of switch production, in particular to an injection mold for a switch rocker. Background Art

[0002] A panel switch is a switch used to control electrical devices or circuits, typically mounted on a wall or panel. They are commonly used to control household appliances such as lights, outlets, and fans. Panel switches typically have a button or rocker that you move to different positions to turn the appliance on or off.

[0003] Common panel switches are all injection molded. In the process of injection molding for rocker switches, multiple products are usually molded at the same time. The current distribution of runners and mold cavities should theoretically ensure balanced molding effects for each part. However, in reality, the glue flow is unbalanced, as shown in the attached figure of the manual. Figure 1 In the 1*8 mold shown, the four middle molding cavities are easy to fill during injection molding, while the four outer cavities are not easy to fill with glue. As a result, after all the cavities are filled, the parts with fast glue flow will have burrs or excessive glue, resulting in inconsistent product quality and increased subsequent workload. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art, such as the phenomenon of burrs or excessive glue on parts with fast glue flow, which causes inconsistent product quality, and proposes a switch rocker injection mold.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A switch rocker injection mold is designed, comprising a mold base having multiple molding cavities, a mold core being disposed within the molding cavities, and a plurality of flow channels being provided on the upper surface of the mold base, the plurality of flow channels being sequentially connected to the plurality of molding cavities;

[0007] Wherein, a mixing structure is further provided on the upper surface of the mold base, and the mixing structure is used for mixing rubber materials, and a plurality of the flow channels converge into the mixing structure.

[0008] Furthermore, the hybrid structure includes an annular groove formed above the mold base, a transverse groove is radially connected to the annular groove, and the middle of the transverse groove has an injection port opposite to it.

[0009] Furthermore, the flow channel includes two main flow channels and a plurality of branch flow channels, each of the main flow channels is connected to at least two branch flow channels, and the two main flow channels are connected to both sides of the annular groove.

[0010] Furthermore, a first through hole is provided in the annular groove, and a second through hole is provided in the middle of the transverse groove.

[0011] Furthermore, it also includes an inclined ejector rod arranged in the mold core, and the inclined ejector rod is used to cooperate with the mold core to form the buckle position of the product.

[0012] The utility model proposes a switch rocker injection mold, which has the beneficial effect that: in the utility model, by arranging a mixing structure above the mold base, the injection molded rubber material can be mixed after being connected with the runner, and the relative balance of the rubber material temperature can be ensured, so that the molding quality of the left-shift products on both sides and the middle left-shift product is relatively uniform, so as to reduce the phenomenon of burrs or excessive glue on the middle left-shift product. The structural design is simple and novel, which greatly improves the molding quality of the product and reduces the subsequent workload. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-3 An embodiment of the present invention discloses a switch rocker injection mold, comprising a mold base 1 having a plurality of molding cavities 11, a mold core 2 being disposed within the molding cavities 11, and a plurality of flow channels 12 being formed on the upper surface of the mold base 1, the plurality of flow channels 12 being sequentially connected to the plurality of molding cavities 11;

[0019] A mixing structure 13 is further provided on the upper surface of the mold base 1 . The mixing structure 13 is used to mix the rubber material. A plurality of the flow channels 12 converge into the mixing structure 13 .

[0020] In some embodiments, the mixing structure 13 in the present invention includes an annular groove 131 formed above the mold base 1, and a transverse groove 132 is radially connected in the annular groove 131. The middle part of the transverse groove 132 has an injection port opposite. During specific operation, when the hot melt adhesive enters the middle part of the transverse groove 132 along the injection port, the adhesive will be initially mixed along the center of the transverse groove 132, and then diverted to both sides to complete the initial mixing of the adhesive.

[0021] On the basis of the above embodiments, the flow channel 12 in the present invention includes two main channels 121 and multiple branch channels 122. Each of the main channels 121 is connected to at least two branch channels 122. The two main channels 121 are connected on both sides of the annular groove 131. Specifically, when the rubber material flows, the rubber material on both sides of the annular groove 131 will converge together again, and the convergence point is the connecting port of the main channel 121. At this time, the rubber material on both sides will be mixed for the second time here. After the rubber material is mixed, the injection molding factor is relatively stable, and the injection molding will be relatively balanced.

[0022] It should be noted that in this embodiment, a first through hole 133 is provided in the annular groove 131, and a second through hole 134 is provided in the middle of the transverse groove 132. The first through hole 133 and the second through hole 134 can be used to branch other flow channels, thereby improving the molding efficiency when molding multiple products.

[0023] It should be noted that the present invention also includes a tilted ejector rod 3 arranged in the mold core 2, and the tilted ejector rod 3 is used to cooperate with the mold core 2 to form the buckle position of the product. The structure and driving method of the tilted ejector rod 3 are existing technologies. It is separated from the buckle position of the product after moving, thereby improving the convenience of forming the buckle position of the product.

[0024] In summary, in the present invention, by setting a mixing structure 13 above the mold base 1, after being connected to the runner, the injected rubber material can be mixed, and the relative balance of the rubber material temperature can be ensured, so that the molding quality of the left-end products on both sides and the middle left-end products is relatively uniform, so as to reduce the burrs or excess rubber in the middle left-end products.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
