Product Description

Introducing the Stop Bolt, a masterfully engineered mechanical fastener boasting a specialized structure and multifaceted functionality. Perfectly designed for molds and precision apparatus, delve into its comprehensive description below:

------

1. Core Structure and Design Features

Shoulder Design: Features a cylindrical shoulder seamlessly nestled between the head and screw, ensuring a snug fit with the fastened component, thus executing precise positioning and halting movement.

Material and Performance: Crafted from premium SCM435 alloy steel, with a hardness rating of 33-38HRC, it showcases an impressive blend of high toughness, exceptional wear resistance, and outstanding heat resilience, making it ideal for elevated temperature environments.

• Integrated Usage: Commonly paired with bolt pull rods, it effectively controls the mold opening stroke of the parting surface via threaded connections, resulting in a more compact mold design.

------

2. Function and Capabilities

• Precise Positioning and Stopping: The shoulder design ensures fixed component positioning, preventing movement deviations, ideal for scenarios requiring precision (such as fixed mold seat plates and flow channel push plates in three plate molds).

Anti-Vibration and Stability: Provides robust mechanical coordination (without reliance on friction), enhancing connection reliability and vibration resistance.

• Thermal Deformation Control: Minimizes thermal expansion-induced deformation in high-temperature molds, thereby prolonging mold longevity.

------

3. Application Scenarios

In mold applications, it controls three plate mold opening strokes, streamlining mold structures and enabling miniaturization.

Mechanical Transmission: Essential for devices needing high-precision positioning in automotive and aerospace equipment.

High-Temperature Environments: Its superb heat resistance renders it perfect for high-temperature sectors like metallurgy and injection molding.

------

4. Usage Guidelines

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

Installation Requirements:

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

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

Prior to installation, threads must be cleaned and lubricated to avert locking.

Quality Inspection: Ensure thread connections pass gauge tests, and verify fastening status post-installation.

------

5. Distinction from Ordinary Bolts

• Enhanced Functionality: Merges positioning with fastening, unlike ordinary bolts that merely fasten;

Structural Distinction: The unique shoulder design provides mechanical stopping, absent in ordinary bolts.

------

Summary

Plug in screws adeptly address the demands for positioning, vibration resistance, and heat endurance in precision equipment through their distinctive shaft shoulder structure and material excellence. They are pivotal in mold and high-precision machinery realms. This design masterfully balances functionality with reliability, necessitating strict adherence to installation protocols for optimal performance.
