Product Details

Product Overview

This mold is a large injection mold specifically designed for automotive front protective panels (such as A-pillar upper panels). By optimizing the gating system and core-pulling mechanism, it solves the problems of difficult filling of thin-walled parts and easy breakage of angled ejector pins. Both the mold cavity and core material are made of P20 steel, and the mold base is made of 45# steel. It is equipped with a water cooling system and a hot runner + side gate combination injection system to ensure high precision and durability.

Product Features

High-efficiency Production

◎ Molding cycle ≤ 30 seconds, hot runner system reduces waste and improves efficiency.

Structural Optimization

◎ The double-slanted push rod core-pulling mechanism enhances demolding stability and reduces the risk of breakage.

Durable Material

◎ P20 steel mold cavity/core material + 45# steel mold base, balancing hardness and impact resistance.

Precise Cooling

◎ The water cooling system quickly controls the temperature, ensuring the dimensional stability of the plastic parts.

Multi-alveolar Design

◎ Two alveoli (right tooth + left tooth) to accommodate complex structures and reduce secondary processing.

Use Cases

Residences and Courtyards

Decoration of gate towers for villas and rural residences to enhance the aesthetics of building entrances.

Public Buildings

Landscape gate towers at the entrances of parks and scenic areas require complex patterns and high durability.

Project Facades

Decorative door frames for commercial projects and municipal engineering projects, combining practicality and aesthetics.

Conclusion

Frequently Asked Questions

Q What material is used for the mold cavity and core in this automotive injection mold? ▼

Both the mold cavity and core are made of P20 steel, which offers excellent hardness, toughness, and machinability. The mold base is made of 45# steel, which balances structural strength and cost-effectiveness for large injection molds.

Q What is the molding cycle time for this mold? ▼

The molding cycle is designed to be ≤ 30 seconds, achieved through an optimized hot runner system combined with an efficient water cooling system. This ensures high-efficiency production while maintaining consistent part quality.

Q How does the core-pulling mechanism prevent ejector pin breakage? ▼

This mold uses a double-slanted push rod core-pulling mechanism, which distributes ejection forces more evenly across the part surface. This design significantly enhances demolding stability and reduces the mechanical stress that typically causes angled ejector pin breakage in thin-walled automotive parts.

Q What gate system does this mold use and what are its advantages? ▼

This mold uses a hot runner system combined with a normal side gate. The hot runner system helps reduce material waste, shorten cycle times, and improve surface finish on the molded parts. The side gate design ensures proper filling of complex thin-walled automotive panels without causing weld lines or short shots.

Q How many cavities does this mold have and what parts can it produce simultaneously? ▼

This mold features a 2-cavity design — one right tooth cavity and one left tooth cavity. This multi-alveolar configuration allows both left-hand and right-hand automotive front protective panel components to be produced in a single molding cycle, reducing secondary processing and improving overall production efficiency.

Q What applications is this injection mold suitable for? ▼

This mold is specifically designed for automotive front protective panels such as A-pillar upper panels. Beyond automotive applications, the technology and structural design principles are also applicable to decorative architectural components including gate towers for residential villas, landscape entrances for parks and scenic areas, and decorative door frames for commercial and municipal engineering projects.
