Description

Technical Field

[0001] The utility model relates to the technical field of sealing devices, in particular to an exhaust sealing device for a mold. Background Art

[0002] The exhaust sealing device for molds is an important device used in the mold manufacturing process. It has three main functions. First, the exhaust sealing device can effectively exhaust the gas in the mold to avoid the generation of bubbles or air gaps, thereby ensuring the quality of the product. Secondly, it can ensure the pressure balance inside the mold and prevent the mold from deformation or damage during operation. Finally, the exhaust sealing device can also improve the production efficiency of the mold and reduce the downtime in the production process, thereby reducing production costs and improving production benefits. In general, the exhaust sealing device for molds plays a vital role in the mold manufacturing process. It can not only improve the quality of the product, but also improve production efficiency and reduce production costs.

[0003] At present, when using a top-open venting mold, either venting or sealing is difficult. If it is difficult to vent, the gas inside the mold cannot be effectively discharged, which may cause bubbles or air gaps to form in the product. If it is difficult to seal, gas leakage may occur, affecting the sealing performance of the system. Therefore, it does not meet the existing needs. In this regard, we propose a venting sealing device for the mold. Utility Model Content
