How many of these elements in injection molds do you know?

Injection molds can be divided into parting surfaces, structural components, mold precision, injection systems, plastic shrinkage rates, and factors affecting product size accuracy. Let's take a look!
1. Parting surface: This is the contact surface between the mold and the core when the injection mold is closed. The selection of its position and form is influenced by factors such as product shape and appearance, wall thickness, forming methods, post-processing techniques, mold types and structures, demolding methods, and the structure of the forming machine.
2. Structural components: These include sliders, inclined ejectors, and straight ejectors in complex molds. The design of structural components is crucial as it relates to the product's lifespan, processing cycle, cost, and product quality. Therefore, the design of complex core structures requires the designer's comprehensive ability, striving for simpler, more durable, and more economical design solutions.
3. Mold precision: This includes avoiding jamming, precise positioning, guide posts, and locating pins. The positioning system affects the appearance quality of the product, mold quality, and mold lifespan. Different positioning methods are chosen based on the mold structure. The control of positioning accuracy mainly depends on processing. The positioning of the inner mold is primarily considered by the designer, who aims to create a more reasonable and easily adjustable positioning method.
