Description

Technical Field

[0001] This utility model relates to the field of IMD injection molding technology, and in particular to an IMD injection molding device for a washing machine control panel. Background Technology

[0002] The washing machine control panel is the core interactive component for users to operate the washing machine, typically integrating buttons, knobs, and a display screen. It allows users to select washing modes, adjust parameters such as water level, water temperature, and spin speed, and control functions like starting, pausing, and scheduling. Some panels are equipped with a display screen that shows real-time washing progress, remaining time, and fault alerts, helping users intuitively understand the washing machine's operating status. Simple operation allows the washing machine to complete the washing process according to user needs, making it a crucial interface between the user and the washing machine's functions.

[0003] Injection molding of washing machine control panels combines IMD (Injection Molding) with injection molding to produce control panels. First, a thin decorative layer printed with button markings and patterns is placed into an injection mold. Then, plastic raw material is injected, allowing the decorative layer and the plastic substrate to be integrally formed within the mold. This process makes the panel patterns wear-resistant, scratch-resistant, and less prone to peeling off. It also simplifies the production process and allows for a variety of aesthetic effects, ensuring the control panel is both beautiful and durable, suitable for frequent contact scenarios during daily washing machine operation.

[0004] When the rigid surface of a traditional mold cavity comes into contact with the film, wrinkles are easily caused by uneven local pressure. In the arc transition area of ​​the control panel, the film may be suspended due to the bonding gap. During injection, the impact of the melt will cause the pattern in this area to be stretched and deformed. In addition, the single-point layout of the traditional pressing component is prone to uneven force on the edge of the film, which can cause it to lift up and result in flash after injection. Over time, the elastic silicone pad may also loosen its fit with the mold cavity due to the displacement of injection pressure, affecting the positioning accuracy and increasing the risk of film breakage.

[0005] Therefore, it is necessary to provide an IMD injection molding device for a washing machine control panel to solve the above-mentioned technical problems. Utility Model Content

[0052] The working principle of the IMD injection molding device for the washing machine control panel provided by this utility model is as follows:

[0053] Multiple limiting bolts 16 are provided on the top of the lower mold 7, and a docking groove 13 is opened on the top of the lower mold 7. At the same time, multiple docking holes 18 that engage with the limiting bolts 16 are opened on the bottom of the upper mold 9, and a pressure strip 17 that can be inserted into the docking groove 13 is provided on the bottom of the upper mold 9. Then, a high-temperature resistant elastic silicone pad 15 with perforations 14 is placed inside the cavity of the lower mold 7, and the surface of the elastic silicone pad 15 of the corresponding model has grooves that coincide with the film pattern. In actual use, the lower mold 7 of the corresponding shape is installed through the first quick-release assembly 6, and the upper mold 9 of the corresponding shape is installed through the second quick-release assembly 10. The perforations 14 on the elastic silicone pad 15 are then aligned with the limiting bolts 16, so that the elastic silicone pad of the corresponding model... The silicone pad 15 and the inner surface of the cavity of the lower mold 7 are fully adhered. Then, the film and the surface of the elastic silicone pad 15 are adhered, and the film pattern is aligned with the shallow groove of the elastic silicone pad 15. At the same time, the edge of the film is aligned with the limit pin 16, and the edge of the film is positioned above the docking groove 13.

After the docking is completed, the plastic melt can be injected into the space between the film and the upper mold 9 through the injection hole on the upper mold 9. During injection molding, the elastic silicone pad 15 offsets the impact pressure of the melt through elastic deformation, while the limit pin 16 ensures that the silicone pad does not shift, maintaining the film's adherence.

[0054] Compared with related technologies, the IMD injection molding device for the washing machine control panel provided by this utility model has the following advantages:

[0055] To improve the injection molding effect of the control panel IMD, multiple limit bolts 16 are set on the top of the lower mold 7, and a docking groove 13 is opened on the top of the lower mold 7. At the same time, multiple docking holes 18 that engage with the limit bolts 16 are opened on the bottom of the upper mold 9, and a pressure strip 17 that can be inserted into the docking groove 13 is set on the bottom of the upper mold 9. Then, a high-temperature resistant elastic silicone pad 15 with perforations 14 is set inside the cavity of the lower mold 7, and the surface of the elastic silicone pad 15 of the corresponding model has grooves that overlap with the film pattern. This design greatly reduces film wrinkles, effectively controls the problem of pattern deformation in the arc area, and significantly improves the consistency of product appearance. The elastic silicone pad 15, together with the limit bolts 16, has stronger stability, and the pressure strip 17, together with the docking groove 13, minimizes the occurrence of film edge lifting. The amount of edge flash after injection molding is minimal, reducing subsequent trimming processes and improving production efficiency.
