[0035] Example 1
[0036] This embodiment provides a mold for processing trunk wiring harness switches, as shown in the attached figure. Figures 1-5 As shown, it includes:
[0037] A turntable 11 is provided, with two fixed moving molds 12. The turntable 11 is rotatable; specifically, a drive source is connected below the turntable 11 to rotate it. This drive source can be a motor or other device. In this embodiment, the turntable 11 rotates 180° at a time, adjusting the positions of the two moving molds 12. One moving mold 12 is used to form the first component 13, and the other moving mold 12 is used to form the second component 14, creating a cyclical action that improves processing efficiency.
[0038] The first fixed mold 15, together with the moving mold 12, forms a first cavity 100, which is used to mold the first component 13. When the first fixed mold 15 is engaged with one of the moving molds 12, injection molding is performed to form the first component 13.
[0039] The second fixed mold 16, together with the moving mold 12 containing the first component 13, forms the second cavity 101, which molds the wire harness switch. After the first component 13 is processed, the first fixed mold 15 separates from the moving mold 12, and then rotates to a position below the second fixed mold 16. The second fixed mold 16 then mates with the moving mold 12 containing the first component 13. After mating, injection molding is performed to form the second component 14. At this point, the second component 14 is attached and fixed to the first component 13, achieving a secondary injection molding effect. The second cavity 101 is provided with an air blowing channel 17. During the unloading process of the second cavity 101, external gas is blown through the air blowing channel 17 to perform the unloading action. Because the second component 14 is made of flexible material, adhesion can easily occur during direct unloading. By using the air blowing operation, the wire harness switch is first separated from the core during unloading, and then the core is pulled out for unloading. First, by correspondingly setting two fixed molds and a moving mold 12, a secondary injection molding effect is achieved, which improves the connection strength between the first component 13 and the second component 14. Furthermore, the secondary injection molding process eliminates the need for subsequent assembly; the demolded product is the structure of a wire harness switch, making processing convenient and saving assembly steps, thus greatly improving processing efficiency. In this embodiment, the first fixed mold 15 and the second fixed mold 16 can move simultaneously perpendicularly toward the turntable 11, or they can be set independently. The wire harness switch includes a first component 13 and a second component 14, which are assembled to achieve a fixed effect. Both the first component 13 and the second component 14 are made of plastic, but the strength of the first component 13 is higher than that of the second component 14. The second component 14 is specifically a flexible structure, providing a certain cushioning feel during pressing. The first component 13 is used for installation and fixation.
[0040] Specifically, as shown in the attached document Figures 2-5 As shown, the air blowing channel 17 is located in the moving mold 12. The upper end of the air blowing channel 17 is connected to the second cavity 101, and the air blowing channel 17 points vertically downwards. The other end of the air blowing channel 17 is connected to an external air passage. This structural arrangement creates an upward blowing effect, allowing for better material unloading after injection molding. Alternatively, the air blowing channel 17 can also be located in the second fixed mold 16.
[0041] Specifically, as shown in the attached document Figures 1-5 As shown, the second component 14 has a raised portion 141, which is formed by air blowing. The raised portion 141 is a product process requirement, causing it to bulge upwards towards the top surface, with its height not exceeding 1mm above the top surface of the first component 13. Upward air blowing creates the raised portion 141 and achieves the demolding effect. The number of air blowing channels 17 can be one or more, and the connection position between the air blowing channel 17 and the second cavity 101 can be adjusted according to actual needs.
[0042] Specifically, the blowing pressure value is obtained through Moldex3D simulation. The magnitude of the blowing pressure is simulated by software to achieve a precise control effect, but it can also be determined by human experience through multiple tests. In addition, the blowing duration can also be obtained through Moldex3D simulation.
[0043] Specifically, as shown in the attached document Figures 2-5 As shown, the moving mold 12 is fixed with an even number of inserts 18, and two inserts 18 cooperate to form part of the first cavity 100. Each insert 18 has a through hole 181, which obliquely penetrates the insert 18. The first fixed mold 15 has a wedge 151 that extends into the through hole 181. The wedge 151 and the through hole 181 cooperate to form a locking effect. When the mold opens, the two inserts 18 face outwards, creating a demolding effect.
[0044] Specifically, as shown in the attached document Figures 2-5 As shown, the insert 18 has two through holes 181, and the first fixed mold 15 has an equal number of inclined blocks 151 as the number of through holes 181. The multiple through holes 181 are provided to create a stable driving effect.
[0045] Specifically, the first fixed mold 15 and the moving mold 12 cooperate to form four first cavities 100, and the second fixed mold 16 and the moving mold 12 cooperate to form four second cavities 101. The number of cavities can be adjusted according to actual needs.
[0046] Specifically, as shown in the attached document Figure 5 As shown, the moving mold 12 is provided with a circulating water channel 19, which surrounds the outside of the first cavity 100 and the second cavity 101. The arrangement of the circulating water channel 19 better achieves a cooling effect, making the temperature of each cavity uniform.
[0047] Specifically, in addition to these features, other inserts are provided to form other features of the wire harness switch, such as the chamber with the first component 13 facing downwards, etc. Those skilled in the art should know how to design these features, so they are not described in detail in this embodiment.
[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
