Do you know what structures need to be considered in the design of injection molds? The editor of Low price Big size injection mould will take you to a brief understanding.
1. Parting surface: that is, the contact surface where the cavity and the mold base cooperate with each other when the injection mold is closed. The selection of its position and method is affected by the product appearance and appearance, wall thickness, forming method, post-production process, injection mold type and structure, mold ejection method and forming machine structure and other factors.
2. Structural parts: that is, the rail sliders, inclined guide posts, straight top blocks, etc. of the complicated injection mold. The design of structural parts is very important, which is related to the service life of the injection mold, the production and processing cycle time, cost, product quality, etc. Therefore, the design of the complex key structure of the injection mold requires a higher comprehensive ability of the designer, and it is simpler to pursue perfection as much as possible. , More durable, more economical development of the program design.
3. Mold accuracy: namely, avoid card, precise and precise positioning, positioning pin, circlip, etc. The mobile phone positioning system is related to the product appearance quality, injection mold quality and service life. According to the different injection mold design, different precise positioning methods are selected. The key to control the accuracy level is through production and processing. The precise positioning of the core mold is mainly the designer's sufficient Considering that, a more effective and easy-to-adjust precise positioning method is designed.
4. Pouring system: the feeding safety channel from the nozzle of the plastic machine to the middle of the die, including the flow channel, the separation channel, the glue inlet and the cold material hole. In particular, the selection of the glue inlet should be beneficial for the molten plastic to fill the die with good fluidity, and the solid flow channel and glue inlet cold material attached to the product are easy to be ejected from the mould when the mould is ejected. give elimination.
The above is the introduction of the Low price Big size injection mould editor: a brief introduction to the structural knowledge that needs to be considered in the design of injection moulds.
