Description

Technical Field

[0001] This invention relates to the field of automotive parts mold technology, and in particular to a European-style mud groove corner injection mold. Background Technology

[0002] "Mixed seal" is a common term used in the domestic mold and automotive parts industry for the sealing strips on the inner and outer sides of car doors. Traditional sealed seals often use a simple "U" or "C" shaped structure with a limited number of lips, relying mainly on unilateral compression to achieve a seal. European-style sealed seals, on the other hand, generally employ a multi-lip composite design, including a first lip, a second lip, and a third lip, with the third lip being shorter. (Refer to the attached diagram in the instruction manual.) Figure 6 The multi-layered contact design enhances clamping force and sealing, effectively reducing vibration and noise, especially when the glass is partially open. Furthermore, the European-style mud trough has a more complex cross-sectional curve, potentially incorporating guide channels or buffer structures to optimize airflow and drainage efficiency.

[0003] The main difficulty in processing and producing European-style mud tanks lies in the variety of cross-sectional shapes, including structures such as multi-lip edges, cavities, and hooks, in pursuit of higher sealing performance. This results in complicated and difficult insertion and removal of parts, and the different structures can easily cause shaking during the injection molding process, directly affecting the production efficiency of the product.

Moreover, according to the characteristics of the product, it can be positioned and clamped from different directions and angles before injection molding to prevent product movement during injection molding from affecting quality and reducing the workload of workers. The dual-cavity design of the mold greatly improves production efficiency and reduces the production cost per unit. The entire mold operation is completed by a mechanical structure driven by hydraulic cylinders and pneumatic cylinders, making it convenient for workers to operate and highly efficient in production.
