Technical Field

[0001] This utility model relates to the technical field of water stopper accessories, specifically to a silicone-coated water stopper. Background Technology

[0002] A water stopper is a metal part used in plastic molds or any water cooling or heating system to fill the gaps according to the required flow direction. Applications of water stoppers include: plastic molds, water cooling systems, and water heating and heat conduction systems.

[0003] In the injection molding process of plastic parts, many cooling or heating water channels are usually designed. However, the traditional water stop valves used in injection molds rely on the expansion of rubber for sealing. When the water temperature is high, water leakage is likely to occur. The sealing effect is limited, and it usually cannot achieve a combination of water blocking and air blocking. In addition, it is not resistant to high temperatures, which limits its wide application, reduces its service life, and greatly reduces its efficiency. To address the aforementioned issues, application number CN201420197756.5 discloses a high-sealing injection mold water-stopping plug, comprising a copper sleeve with several rubber rings evenly distributed on the outside of the sleeve, and an aluminum fastening plug inside the sleeve. The fastening plug is composed of several frustums connected together, with a raised ring on the outer edge of the bottom surface of each frustum, each raised ring located within each rubber ring. An expansion screw is located inside the fastening plug. The advantages of this invention are: significant expansion effect at high temperatures, achieving a combination of water and air blocking, and greatly improving the efficiency of water and air blocking; high temperature resistance; simple structure; cost-effectiveness; ease of use; and extended service life. However, this water-stopping plug has the following problems: existing water-stopping plugs are mostly of fixed specifications, unable to be adjusted according to requirements for size or friction, resulting in low applicability and high customization costs; furthermore, the ends of existing water-stopping valves are flat, lacking a guiding structure, affecting subsequent installation efficiency.
