Which principle ensures that a mold can replicate the shape and details of a product accurately?
This principle focuses on the mold's ability to meet product molding requirements.
This principle is more about cost-efficiency and material selection.
This principle involves making the mold easy to process and manufacture.
This principle focuses on the mold's strength, stiffness, and service life.
The functionality principle ensures that the mold meets the product molding requirements by replicating the product's shape, size, and details accurately. It involves designing the mold to accommodate the material properties and molding processes, ensuring uniform filling of the mold cavity.
What is a key consideration under the economy principle in mold design?
High-quality steel is used only for critical parts, not for all parts.
Standard parts help reduce manufacturing costs and improve interchangeability.
Complex structures often increase costs and processing time.
Appearance precision should be balanced with functional needs to control costs.
The economy principle in mold design emphasizes using standard parts to reduce manufacturing costs and enhance interchangeability. This approach simplifies the mold structure, avoids unnecessary complexity, and allows for cost-effective maintenance and part replacement.
What is a key consideration when designing the pouring system for plastics with poor fluidity in injection molds?
A small gate might restrict flow, causing defects.
Larger gates help ensure the plastic flows smoothly, reducing short shots.
Single-point gates may not distribute flow evenly for poor fluidity materials.
Lower temperatures can worsen flow issues.
For plastics with poor fluidity, increasing the gate size allows for smoother entry of the plastic melt into the cavity, reducing issues like short shots. Small or single-point gates may restrict flow, and lowering mold temperature typically exacerbates flow problems.

This principle focuses on meeting product molding requirements, such as uniform filling of complex structures.
This principle is more concerned with cost reduction rather than product accuracy.
This principle emphasizes ease of manufacturing and assembly.
This principle focuses on mold strength and longevity, not on replication accuracy.
The functionality principle ensures that the mold can accurately replicate the product's shape, size, and details. It involves designing for uniform plastic filling and avoiding defects like short shots. Other principles focus on cost, manufacturing ease, and longevity, not on replication accuracy.
What factor is NOT directly related to the principle of economy in mold design?
This choice is about balancing cost with product batch size and precision needs.
Standard parts reduce manufacturing costs and simplify maintenance.
This is related to functionality and demolding, not cost efficiency.
Reducing costly material use aligns with economic efficiency goals.
Ensuring smooth ejection from the mold is related to the functionality principle, focusing on effective product demolding. The principle of economy revolves around cost-efficiency strategies like material selection and using standard parts to reduce costs, not demolding efficiency.
What is a key consideration for ensuring reliable demolding in injection mold design?
Complexity isn't always better. Consider ease and reliability.
Ejector pins are essential for smooth demolding.
The design should cater to the product's unique features.
Fixed mechanisms may not adapt well to product variations.
Designing an effective ejector system based on the product's shape and structure is crucial for reliable demolding. This ensures that products with complex structures are ejected smoothly without damage, which is not achievable with overly complex or inflexible mechanisms.
How can mold material selection impact production costs in injection mold design?
High-cost materials may not always be necessary.
Availability doesn't guarantee suitability or cost-effectiveness.
Consider long-term use and production demands.
Different components have different requirements.
Selecting mold materials based on the mold's expected service life, production batch size, and precision requirements can significantly impact production costs. Using high-quality steel for critical parts and economical options elsewhere can optimize both performance and cost-efficiency.
