Optimized design of injection mold
2020-05-29
Most of the adjustments and improvements to injection molding tools are based on computer-aided engineering technology for auxiliary production. This includes CAD, CAE, and CAM technology, as well as CNC machining and other processes, and began to improve and optimize the structure of injection molds.


Design and analysis of injection mold

Injection mold design is to complete the production and design of the mold through the use of computer software. (injection molding die). Two technologies greatly increase production efficiency, namely CAE and Pro/E. CAE technology is widely used in plastic molding simulation. Carry out process research and analysis for CAD models and related products, as well as the mold forming process, to reduce mold scraps caused by too many mold trials in the experiment and the entire operation time is too long. (plastic injection mold making). The biggest function of Pro/E is to adjust and correct the entire process of mold injection.


Optimization and improvement of gating system

The gating system mainly refers to all the routes in the nozzle of the injection molding machine after the material passes through the cavity, mainly including the main runner, the runner, and the gate, 1. The center position of the template in the injection mold is the runner, and it can also be used with most runners. Converge. 2. Try to make the heat loss and the drag force after the flow smaller in the runners. The good splitting effect is the circular cross-section, but most of the injection molds use U-shaped or trapezoidal cross-sections. 3. The gate optimization in the gating system The design uses a single-part two-panel style for injection molds.


Cooling system design

The optimized cooling system is transformed into two upper and lower cooling water channels. In each layer, there are distributed dual channels, the design temperature is 50 degrees Celsius, the melt temperature is 230 degrees Celsius, the ejection temperature is 90 degrees Celsius, and the shear rate is set at 12 s-1; the dial of the model is precisely controlled. (injection mold components). The slope of the mold is used to mold the mold using the pattern generated during cutting.
