Standard Precision Large Gate Mold Base

The SIKAIDA Standard Precision Large Gate Mold Base is specifically designed for two-platen injection molding systems. It utilizes a large gate for stable melt flow and convenient operation, making it a cost-effective choice for mass production of medium-precision plastic parts. As a reliable supplier, SIKAIDA adheres to international standards, ensuring product interchangeability and consistency, and providing rapid delivery services to global buyers.

Structural Features

This Standard Precision Large Gate Mold Base features a two-plate structure, composed of standard components such as a fixed mold base plate and a moving mold base plate. Equipped with precision guide pillars and bushings, it ensures accurate alignment of the cavity and core. The large gate design allows the melt to directly enter the cavity, resulting in low flow resistance, stable filling, and compatibility with mainstream standards such as LKM, HASCO, and DME, offering strong interchangeability.

Applications

The Standard Precision Large Gate Mold Base is suitable for injection molding of most thermoplastic plastics such as PP and ABS, meeting medium precision requirements of IT7-IT8 grades. It is widely used in the production of household appliance housings, automotive interior parts, electronic product housings, and everyday consumer goods such as plastic buckets.

Manufacturing Advantages

SIKAIDA's mold base series offers significant advantages: In terms of cost, simplified processes and high utilization of standard parts reduce costs by 30%-50% compared to high-precision molds; in terms of cycle time, high standardization allows for manufacturing completion in 15-25 days, shortening the time by more than 40% compared to custom high-precision molds; in terms of maintenance, the simple structure and standardized components facilitate daily maintenance and reduce downtime.

Technical Parameters

Standard Precision: Large Gate Mold Base precision grade IT7-IT8, surface roughness Ra 0.8-1.6μm; mold base made of 45# steel or P20 pre-hardened steel, cavity and core made of P20, 718H, and other mold steels; cooling water channel spacing 80-120mm, mechanical ejector pin spacing 150-200mm, suitable for 50-500 ton injection molding machines.

Production Process

1. Design Stage

The design stage uses software such as UG and SolidWorks to complete 3D modeling and cavity/core design, generate a standard parts list and procure them, and output drawings to guide subsequent processing.

2. Processing Stage

The processing stage consists of three parts: rough machining to remove excess material, machining the planes and holes of major parts; finish machining using high-speed CNC machining of precision parts to ensure the flatness of the parting surface and the accuracy of the cooling water channels; surface treatment includes tempering of the cavity and core, fine grinding of the parting surface, and polishing of the outer surface as needed.

3. Assembly and Debugging

Assembly and debugging begin with installing standard components such as guide pillars and guide sleeves. After testing the cooling system for leaks using water, a trial mold is run on the injection molding machine to adjust parameters. Mass production can begin after the first piece passes inspection.

Development Trends

The development of Standard Precision Large Gate Mold Base exhibits four major trends: standardization and modularization improve interchangeability and shorten cycle time; high-efficiency processing technology enhances precision and efficiency; intelligent manufacturing enables production monitoring and optimization; and lightweight and energy-saving design reduces costs and energy consumption.

SIKAIDA Standard Precision Large Gate Mold Base combines simplicity, efficiency, and economy, making it a core piece of equipment for general-purpose plastic injection molding. Leveraging its professional factories in China, SIKAIDA continuously optimizes quality, providing stable and cost-effective mold base solutions for the global manufacturing industry.
