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?

Both the mold cavity and core are made of P20 steel, which offers excellent hardness, wear resistance, and machinability — making it ideal for high-volume automotive injection molds.

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

The molding cycle is ≤ 30 seconds, thanks to the optimized hot runner system and efficient water cooling design, ensuring high production throughput with minimal waste.

Q How does the cooling system work in this mold?

The mold uses a water cooling system that rapidly controls the mold temperature after each injection cycle. This helps maintain consistent dimensional stability of the finished plastic parts and shortens the overall cycle time.

Q What type of gate and runner system does this mold use?

This mold uses a combination of a hot runner system and a normal side gate. The hot runner system reduces material waste and improves filling efficiency, while the side gate ensures smooth and balanced injection for thin-walled automotive parts.

Q How many cavities does the mold have, and can it produce both left and right parts simultaneously?

Yes. The mold features a 2-cavity design — one for the right-side part (right tooth) and one for the left-side part (left tooth) — enabling simultaneous production of mirror-image components, reducing lead time and secondary processing.

Q What demolding mechanism is used and how does it prevent ejector pin breakage?

The mold employs a double-slanted push rod core-pulling mechanism combined with a pin ejector and ejection plate system. This structural optimization significantly enhances demolding stability and greatly reduces the risk of angled ejector pin breakage, which is a common issue in complex thin-walled automotive part molds.
