The internal structure of electronic scale molds is complex, mainly due to the following reasons:
1. Functional implementation requirements
High precision weighing requirements: In order to achieve high-precision weighing results, electronic scale molds need to provide the correct installation position and stable support structure for high-precision weighing sensors, ensuring that the sensors can correctly convert object weight into electrical signals. At the same time, space should be reserved for circuit modules such as signal amplification, filtering, and analog-to-digital conversion. The layout and connections of these modules need to be designed correctly to reduce signal interference and ensure the accuracy of weighing data.
Multiple function integration: In addition to basic weighing functions, modern electronic scales may also have multiple functions such as peeling, pricing, data storage, and communication. The mold needs to provide installation space and connection channels for circuit components, display screens, buttons, and other components that achieve these functions, which makes the internal structure more complex. For example, for electronic scales with pricing functions, the mold needs to consider the space for placing components such as microprocessors for calculating prices and memory for storing unit price data.
2. Structural design needs
Load bearing and stability: Electronic scales need to bear objects of different weights, and the mold needs to be designed with a reasonable mechanical structure, such as reinforcing ribs, support columns, etc., to ensure that it will not deform or be damaged during long-term use, and to ensure the stability and reliability of weighing. For large electronic scales, such as molds for weighing scales, it is also necessary to consider the ability to withstand the pressure of heavy objects such as vehicles, as the complexity of their internal structure is higher.
Coordination with external components: Electronic scale molds typically require coordination with multiple external components such as the housing, base, display screen, buttons, etc. In order to achieve correct assembly and good appearance, corresponding card slots, buckles, positioning holes, and other structures should be designed inside the mold for correct connection and fixation with other components.
3. Manufacturing process limitations
Material characteristics and forming requirements: Electronic scale molds usually use materials such as metal or engineering plastics, and the forming process and characteristics of different materials are different. In order to ensure the smooth molding of the mold during the manufacturing process, it is necessary to consider factors such as material fluidity and shrinkage rate, and design complex structures such as flow channels and cooling systems. For example, in injection molded electronic scale molds, in order to evenly fill the mold cavity with plastic, it is necessary to design a reasonable layout of gates and runners.
Processing accuracy and surface quality: In order to ensure the appearance quality and assembly accuracy of electronic scales, the processing accuracy of molds is required to be high. The internal cavity, core and other structures of the mold need to be processed with high precision to ensure the dimensional accuracy and surface quality of the electronic scale components after molding. This may involve complex processing techniques and equipment, such as electrical discharge machining, wire cutting, etc., resulting in a complex internal structure of the mold.
4. Adapt to diverse needs
Product serialization: Electronic scales have different ranges, accuracies, external dimensions, and functional configurations. In order to meet the diverse needs of the market, molds need to have certain universality and adjustability. This requires designing some replaceable modules or adjusting structures inside the mold to meet the production requirements of different products.
Personalized customization: Some customers may have special requirements, such as special shapes, colors, logos, etc. In order to meet these personalized customization needs, special structures or processes may need to be added inside the mold, such as grooves for embedding logos, structures for achieving special surface treatments, etc.
