Product Description

The Stop Bolt is an innovative mechanical fastener, engineered with a distinctive structure and unparalleled functionality, making it an indispensable component in molds and precision equipment. Dive into its comprehensive description:

------

1. Core Structure and Design Features

Shoulder Design: Strategically crafted with a cylindrical shoulder nestled between the head and screw, it ensures a secure fit with the fastened component, delivering exceptional precision in positioning and halting.

Material and Performance: Constructed from robust SCM435 alloy steel, boasting a hardness of 33-38HRC, it masterfully blends high toughness, impressive wear resistance, and superb heat resistance, ideal for challenging high-temperature environments.

• Coordinated Use: Skillfully paired with bolt pull rods to meticulously control the mold opening stroke at the parting surface via threaded connections, this enhances mold design compactness significantly.

------

2. Function and Features

• Positioning and Stopping: The innovative shoulder design secures the components' relative positions, preventing any unwanted deviation, ideal for scenarios demanding precision such as fixed mold seat plates and flow channel push plates in three plate molds.

Anti-vibration and Stability: By harnessing direct mechanical cooperation instead of friction to handle lateral loads, it augments the connection's reliability and vibration resistance considerably.

• Thermal Deformation Control: Effectively mitigates deformation from thermal expansion in high-temperature molds, significantly prolonging mold lifespan.

3. Application Scenarios

In mold industries, it plays a pivotal role in managing the opening stroke of three plate molds, simplifying structures and achieving miniaturization with finesse.

Mechanical Transmission: Essential in transmission devices necessitating precision positioning across automotive and aerospace equipment.

High Temperature Environment: Its outstanding heat resistance earmarks it for high-temperature operations, including metallurgy and injection molding.

4. Usage Guidelines

Selection and Matching: Choose specifications based on material, load, and aperture. Generally, the thread length should be 1.5 times the diameter for optimal performance.

Installation Requirements:

Countersunk hole depth must adhere to these guidelines: W=S (stroke) + shoulder thickness K + 2mm;

Employ a torque wrench to meticulously manage preload force, preventing over or under tightening;

Threads should be meticulously cleaned and lubricated pre-installation to avert locking mishaps.

Quality Inspection: Rigorously ensure the thread connection gauge meets standards, verifying the fastening status post-installation.

5. Distinction from Ordinary Bolts

• Function Extension: Seamlessly merges positioning and fastening, unlike ordinary bolts that solely fasten;

Structural Difference: The ingenious shoulder design facilitates mechanical stopping, absent in regular bolts.

Summarize

Plug-in screws elegantly address the needs for precision positioning, vibration resistance, and high-temperature endurance in equipment through their unique shaft shoulder structure and superior material properties. They stand as vital components in molds and high-precision machinery, where design harmonizes functionality and reliability, necessitating strict adherence to installation specifications for peak performance.
