Product Description

Introducing the Stop Bolt: a mechanical fastener with an ingenious special structure and a function tailor-made for precision molds and equipment. Discover its intricate details:

------

1. Core Structure and Design Features

Innovative Shoulder Design: A cylindrical shoulder seamlessly bridges the head and screw, ensuring a snug fit and precise component positioning during fastening. Truly a marvel of engineering.

Superior Material and Performance: Crafted from SCM435 alloy steel, boasting a hardness of 33-38HRC, it offers exceptional toughness, wear, and heat resistance. Perfect for high-temperature environments where performance cannot be compromised.

• Harmonious Integration: Often paired with bolt pull rods, it orchestrates the mold opening stroke control through threaded connections, allowing for a more compact and streamlined mold design.

2. Function and Capabilities

• Precision Positioning and Secure Stopping: The shoulder design fortifies the fixed positioning of components, eliminating positional deviations. Essential for applications demanding exactitude, like fixed mold seat plates and flow channel push plates in three plate molds.

Enhanced Anti-Vibration and Stability: Its mechanical synergy endures lateral loads, significantly boosting connection reliability and vibration resistance without relying on friction.

• Thermal Deformation Mastery: Skillfully mitigates deformation from thermal expansion in high-temperature molds, extending mold lifespan and maintaining integrity.

3. Versatile Application Scenarios

In mold technologies, it's instrumental for controlling the opening stroke of three plate molds, streamlining the mold structure, and enabling miniaturization.

Mechanical Transmission Mastery: Essential for transmission devices demanding pinpoint precision in industries like automotive and aerospace.

High-Temperature Champion: With unparalleled heat resistance, it thrives in challenging conditions such as metallurgy and injection molding.

4. Expert Usage Guidelines

Thoughtful Selection and Matching: Choose specifications based on material, load, and aperture. Typically, thread length is 1.5 times the diameter for optimal performance.

Critical Installation Requirements:

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

Employ a torque wrench to manage preload force, preventing both over-tightening and under-tightening;

Essential Pre-Installation: Clean and lubricate threads to avoid locking, ensuring smooth installation.

Rigorous Quality Inspection: Verify thread connection gauge qualification and post-installation fastening integrity.
