Product Description

Introducing the remarkable Stop Bolt, a mechanical fastener lauded for its innovative structure and exceptional functionality. A staple within molds and precision equipment, let us delve into its comprehensive description and discover why it's the top choice for industry experts:

------

1. Core Structure and Design Features

Ingenious Shoulder Design: This bolt showcases a cylindrical shoulder nestled between the head and screw. During fastening, it secures the component with unmatched precision, ensuring steadfast positioning and halting movement effectively.

Material and Performance Excellence: Crafted from SCM435 alloy steel, boasting a robust hardness of 33-38HRC, this bolt epitomizes resilience. Its superior toughness, wear resistance, and heat endurance make it an ideal choice for high-temperature environments.

• Harmonious Coordination: Seamlessly integrates with bolt pull rods to masterfully guide mold opening strokes on parting surfaces via threaded connections, heralding a new age of compact mold design.

------

2. Functionality and Role

• Precision Positioning and Stopping: Thanks to its shoulder design, this bolt ensures components are firmly fixed in place, averting deviation. Perfectly suited for applications demanding exact positioning, such as fixed mold seat plates and flow channel push plates in intricate mold systems.

Vibration Resistance and Stability: By leveraging direct mechanical cooperation without relying on friction, it adeptly withstands lateral loads, enhancing connection reliability and anti-vibration capabilities.

• Mastery over Thermal Deformation: Expertly mitigates deformation due to thermal expansion in high-temperature molds, thereby prolonging mold longevity.

3. Application Scenarios

In the realm of molds, it governs the opening stroke of three plate molds, streamlining structures while facilitating miniaturization.

Mechanical Transmission: Vital for transmission devices necessitating high-precision positioning within automotive and aerospace machinery.

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

------

4. Usage Guidelines

Selection and Matching: Choose specifications based on material, load, and aperture, ensuring the thread length is typically 1.5 times the diameter.

Installation Requirements:

Countersunk hole depth must meet criteria: W=S (stroke)+shoulder thickness K+2mm;

Employ a torque wrench to regulate preload force, preventing over-tightening or loosening;

Prior to installation, clean and lubricate threads to avert locking.

Quality Assurance: Confirm thread connection gauge compliance and verify the fastening status post-installation.

------

5. Differences from Ordinary Bolts

• Extended Functionality: Combines both positioning and fastening, whereas ordinary bolts limit themselves to solely fastening.

Structural Innovation: Its shoulder design delivers mechanical stopping, a feature not present in conventional bolts.
