Product Description

The Stop Bolt stands as a meticulously engineered mechanical fastener, boasting an innovative structure and vital functionality. Predominantly embraced within molds and precision apparatus, it plays a pivotal role in ensuring seamless operations. Below is an eloquent exposition of its intricate details:

------

1. Core Structure and Design Features

Shoulder Design: This ingenious cylindrical shoulder nestled between the head and the screw guarantees a snug fit with the fastened component. Through this precision fastening, it adeptly achieves accurate positioning and effective stopping.

Material & Performance: Constructed from top-tier SCM435 alloy steel, boasting a remarkable hardness of 33-38HRC, it seamlessly marries high toughness with exceptional wear and heat resistance. This makes it an unparalleled choice for enduring high-temperature environments.

• Coordinated Use: It is often expertly paired with bolt pull rods to meticulously govern the mold opening stroke on the parting surface via threaded connections, thereby contributing to a more streamlined mold design.

2. Function and Functionality

• Positioning and Stopping: The tailored shoulder design steadfastly locks the components' relative positioning, thwarting any potential deviation. It thrives in scenarios mandating precision, such as securing the fixed mold seat and flow channel push plate in three plate molds.

• Anti Vibration and Stability: It magnifies the reliability and anti-vibration capacity of the connection by employing direct mechanical cooperation, eschewing reliance on friction to counter lateral loads.

• Thermal Deformation Control: With an adeptness in minimizing thermal expansion-induced deformation in high-temperature molds, it significantly extends the mold's operational lifespan.

3. Application Scenarios

In the mold sector, it excels in orchestrating the opening stroke of three plate molds, simplifying structural complexities, and propelling miniaturization.

Mechanical Transmission: It serves as a cornerstone in transmission devices demanding high-precision positioning, notably within automotive and aerospace equipment.

High Temperature Environment: Its robust heat resistance renders it indispensable for high-temperature operations such as metallurgy and injection molding.

4. Usage Guidelines

Selection and Matching: Meticulous selection based on material, load, and aperture is imperative. Typically, the thread length should be 1.5 times the diameter for optimal performance.

Installation Requirements:

The countersunk hole's depth must satisfy the following condition: W=S (stroke) + shoulder thickness K + 2mm;

A torque wrench is essential to control preload force, averting both over-tightening and loosening;

Prior to installation, ensure threads are thoroughly cleaned and lubricated to mitigate the risk of locking.

Quality Inspection: Confirm the thread connection gauge's compliance, and diligently verify the fastening status post-installation.

5. Difference from Ordinary Bolts

• Function Extension: It uniquely integrates positioning and fastening, whereas ordinary bolts are limited to fastening alone.

Structural Difference: The strategic shoulder design endows it with a mechanical stopping capability, a feature absent in ordinary bolts.

------

Summarize

Plug screws triumph in addressing the exacting demands of positioning, vibration resistance, and heat resistance within precision equipment. Their distinctive shaft shoulder structure and material excellence make them indispensable in molds and high-precision machinery. Balancing function with reliability, they necessitate rigorous adherence to installation guidelines to maximize performance and efficacy.
