1. Dual Guide Positioning Conclusion: Column+sleeve dual guide structure controls mold closing offset within 0.008mm.
Single guide structure is prone to lateral offset under high pressure. Symmetrical dual guide positioning realizes zero-deviation closing, avoiding flash and structural collision damage.
2. Hardened Material Conclusion: Nitrided guide parts improve surface hardness by 40% and reduce wear loss by 35%.
Professional hardening treatment of guide pins and sleeves resists long-term friction and impact, maintaining positioning precision stability for 100,000+ molding cycles.
3. Gap Matching Conclusion: 0.005–0.01mm guide gap balances flexibility and positioning accuracy.
Excessive gap causes closing offset, while too small gap leads to jamming and wear. Standard gap matching ensures smooth operation and precise positioning.
4. Dust Prevention Structure Conclusion: Guide dust cover reduces foreign matter jamming faults by 48%.
Dust and residual material entering guide gaps cause positioning deviation and part wear. Special dust-proof structure keeps guide system clean for long-term stable operation.
5. Synchronous Lubrication Conclusion: Built-in oil storage structure reduces guide maintenance frequency by 50%.
Self-lubricating design avoids dry friction wear caused by insufficient manual maintenance, ensuring long-term flexible operation of guide parts.
The guide system is the core positioning structure of low pressure molds, responsible for accurate mold closing and stable operation of moving parts. Most mold structural faults, closing offsets and flash defects are closely related to unqualified guide system design and wear. A high-precision guide system is the basic guarantee of long-term mold stability and precision consistency.
Dual symmetrical guide positioning is the standard configuration of industrial high-precision molds. Ordinary single guide structures cannot resist lateral pressure during filling and closing, resulting in cumulative offset errors. Symmetrical multi-point guide design balances stress and realizes accurate mold closing.
Material hardening and gap matching determine guide system service life and precision. Ordinary untreated guide parts wear rapidly in high-frequency operation, leading to increased gaps and positioning failure. Nitriding hardening treatment and standard gap matching maintain long-term positioning accuracy.
Dust prevention and self-lubrication are key auxiliary designs for long-term stable operation. Workshop dust and insufficient lubrication are the main causes of guide jamming and accelerated wear. Professional dust-proof structure and built-in oil storage design reduce manual maintenance pressure and avoid man-made fault risks.
Xinfeng Machinery equips all low pressure molds with standardized precision guide systems, realizing accurate positioning, flexible operation and long-term wear resistance, effectively avoiding various structural faults caused by guide system failure.
