Key structural elements in injection mold design

There are several important structural elements to consider when designing an audio plastic molding solution inc. The following is a detailed description of them:

1. Parting surface

The parting surface refers to the contact surface between the concave mold and the convex mold when the mold is closed. The choice of its position and form is affected by many factors, including the shape and appearance of the product, wall thickness, molding method, post-processing technology, mold type and structure, demoulding method, and the structure of the molding machine.

2. Structural parts

Sliders, inclined tops, and straight top blocks in complex molds are all structural parts. Their design is crucial because it is directly related to the service life of the mold, processing cycle, cost, and product quality. Designers need to have a high level of comprehensive ability to pursue simpler, more durable, and more economical solutions when designing the core structure of complex molds.

3. Mold accuracy

The accuracy of the mold involves elements such as card avoidance, precision positioning, guide pillars, and positioning pins. The positioning system not only affects the appearance quality of the product, but is also directly related to the quality and life of the mold. According to the different mold structures, it is necessary to select a suitable positioning method. The control of positioning accuracy mainly depends on processing, while the positioning of the inner mold requires the designer to fully consider and design a more reasonable and easy-to-adjust positioning scheme.

4. Casting system

The casting system includes the feed channel from the injection molding machine nozzle to the cavity, including the main channel, branch channel, gate and cold material hole. In particular, the selection of the gate position should be conducive to the molten plastic filling the cavity in a good flow state. At the same time, the solid runner and the cooled gate part attached to the product should also be easy to eject and remove when the mold is opened (except for hot runner molds).

5. Plastic shrinkage and its influencing factors

Plastic shrinkage, mold manufacturing and assembly errors, mold wear and other factors will affect the dimensional accuracy of the product. In addition, when designing compression molds and injection molds, the matching of the process and structural parameters of the molding machine must be considered. At present, computer-aided design (CAD) technology has been widely used in plastic mold design.

Through comprehensive consideration of the above key structural elements, the design quality and production efficiency of customized audio plastic injection mold services can be effectively improved, thereby meeting the market demand for high-quality products.
