1,Description:

 

Shoulder screws are also referred to as shaft shoulder screws, stop screws, stop bolts, brake bolts, equal-height screws, among other names. The shoulder screw works together with the bolt pull rod and serves primarily as a mold component to regulate the opening stroke between the fixed mold base plate, the runner stripper plate, and the stationary mold plate in three-plate molds.

Since it can be positioned on the mold parting surface, the mold design can be made more compact. This product type exhibits elevated hardness, superior toughness, outstanding abrasion resistance, and thermal stability. It is well-suited for high-precision molds and can substantially prolong their service life. In particular, the thermal expansion of precision molds is effectively managed, rendering it appropriate for molds operating in elevated-temperature conditions. Its specification follows ISO 7379. The material for the 12.9 grade plug screw is SCM435 alloy steel, with a comprehensive hardness of HRC40°.

The shoulder screw operates in combination with the bolt pull rod and functions chiefly as a mold accessory to govern the opening distance between the fixed mold seat plate, the sprue ejector plate, and the fixed mold template in three-plate mold configurations.

Owing to its ability to be mounted on the mold parting surface, the mold architecture can be downsized. This category of product demonstrates high rigidity and ductility, coupled with excellent wear endurance and heat tolerance. It is appropriate for precision tooling and contributes to extending their operational lifespan, notably exerting a certain influence on managing the thermal distortion of precision molds. It is applicable to tooling utilized in high-temperature working settings.

2,Applications:

 

Screws are widely used in the industrial field. From large items like spaceships and aircraft to small ones like mobile phones and tables and chairs, they are indispensable. Therefore, they are also known as the "rice of industry".

How important is that tiny screw to an aircraft? According to the data, the Boeing 747There are approximately over 6 million parts in the series of aircraft, and among these parts, fastenersThe proportion accounts for half.There are also quite a few flight safety accidents caused by screw problemsIf experts analyze that one of the reasons for the emergency landing of Sichuan Airlines Flight 3U8633 is very likely to be that the screws of the windshield were substandard or excessive force was applied during installation, which led to cracks in the windshield. It finally falls off.

 

3,Technical Advantages

Alloy steel is a type of steel whose properties are improved by adding alloying elements to carbon steel. It features high strength, wear resistance, corrosion resistance and good weldability.

Alloy steel refers to the addition of one or more alloying elements (such as manganese, chromium, nickel, molybdenum, tungsten, etc.) to ordinary carbon steel to improve its mechanical properties and corrosion resistance. The addition of alloying elements can significantly alter the microstructure and properties of steel, enabling it to meet the requirements of different working conditions.
Main features
1. High strength and hardness: Alloy steel can significantly enhance its strength and hardness by adding alloying elements. For instance, manganese can form a solid solution with iron, enhancing the strength of the matrix.
2. Wear resistance: Alloy steel has excellent wear resistance and can withstand the effects of friction, wear and cutting forces, making it suitable for fields such as mold manufacturing.
3. Corrosion resistance: Certain alloying elements (such as nickel and chromium) can form a dense oxide layer, enhancing the corrosion resistance of alloy steel and enabling it to have a longer service life in harsh environments.
4. Good weldability: The weldability of alloy steel is usually good, making it suitable for structural components that require welding.

5. High-temperature strength: Alloy steel can still maintain high strength and hardness in high-temperature environments, making it suitable for high-temperature working conditions.
