Product Details

Product Overview

This mold is used to manufacture automotive steering shaft protective covers (dust covers). Its core function is to seal the connection between the steering tie rod and the steering gear, preventing dust and mud from entering and protecting the lubrication of the ball joint. The mold uses P20 steel cavity/core material and 45# mold base, combined with hot runner, water cooling system and double groove (right thread + left thread) design to meet the requirements of high-precision and high-efficiency injection molding.

Product Features

High Wear-Resistant Materials

◎ Both the cavity and the core material are made of P20 steel, which has high hardness and wear resistance, extending the mold life.

High-Efficiency Cooling System

◎ Water-cooled design accelerates the molding cycle and improves production efficiency.

Precise Demolding Structure

◎ Pin-type ejector + ejector plate double safety ensure smooth demolding of complex curved surface parts.

Dual-Groove Design

◎ Right and left grooves adapt to different steering system requirements, enhancing versatility.

Hybrid Gate System

◎ Hot runner + ordinary side gate combination, reducing waste and ensuring injection uniformity.

Conclusion

Frequently Asked Questions

Q What material is used for the cavity and core of this steering shaft protective cover mold?

Both the cavity and core are made of P20 steel, a high-hardness, wear-resistant tool steel that ensures long mold service life and dimensional stability during high-volume production.

Q Why does this mold feature a dual-groove (right thread + left thread) design?

The dual-groove design allows the mold to simultaneously produce both right-hand and left-hand threaded dust covers in a single molding cycle. This greatly enhances versatility, enabling the mold to serve different steering system configurations across various vehicle models.

Q How does the cooling system improve production efficiency?

The mold uses a water-cooled design, where cooling channels circulate water around the cavities to rapidly dissipate heat after each injection cycle. This significantly reduces the cooling time per cycle, increasing overall production throughput and lowering unit costs.

Q What is the advantage of combining a hot runner system with a normal side gate?

The hybrid gate system combines the efficiency of a hot runner — which keeps molten material at optimal temperature and eliminates cold runner waste — with the simplicity of a normal side gate for precise injection control. This combination reduces material waste, lowers production costs, and ensures uniform filling of the mold cavity.

Q How does the ejection system ensure smooth demolding of complex curved parts?

The mold employs a dual-safety ejection system combining a pin-type ejector with an ejector plate. This configuration distributes ejection force evenly across the part surface, preventing deformation or damage to the curved geometry of the dust cover during demolding.

Q Is this mold suitable for mass production and large-scale industrial use?

Yes. The mold is engineered to balance efficiency and durability. The P20 steel construction, water cooling system, and optimized gate design collectively support high-cycle mass production, making it fully suitable for large-scale automotive component manufacturing requirements.
