The optimization process includes: the calculation of contour after rough machining, the calculation of large residual machining allowance, the determination of large allowable machining allowance, the division of curved surfaces with residual machining allowance greater than large allowable machining allowance (such as areas with transition radius smaller than rough machining tool radius such as grooves and corners), and the calculation of tool center trajectory during semi-finishing. Most of the existing CAD/CAM softwares for high-speed machining of molds have the function of residual machining allowance analysis, and reasonable semi-finishing strategies can be adopted according to the size and distribution of residual machining allowance. For example, the company's HyperMill and HyperForm software provide pencil milling, re-milling and other methods to remove the corners with large residual machining allowance after rough machining to ensure uniform machining allowance in subsequent processes. Localmilling of Pro/Engineer software has a similar function. For example, the residual machining allowance of local milling is equal to the residual machining allowance of rough machining. In this process, only small-diameter milling cutter is used to remove the uncut corners of rough machining, and then semi-finishing is carried out; If it's manufacturing supervision, you just need to jam the drawings. As for what the other party does, it is the processor's business. If it is a question of determining the cost, you can consult several companies. If the residual machining allowance of local milling process is regarded as the residual machining allowance of semi-finishing, this process can not only remove the uncut corners in rough machining, but also complete semi-finishing. General classification of molds: plastic molds and non-plastic molds;
(1) Non-plastic molds include: casting molds, forging molds, stamping molds, die casting molds, etc.
A. casting mould-faucet and pig iron platform;
B. forging die-automobile body;
C. stamping die-computer panel;
D. Die casting die-high temperature alloy, cylinder block; ;
(2) Plastic molds are divided into:
A. Injection mold-TV shell, keyboard keys (most commonly used)
B. blow molding-beverage bottle;
C. Molding molds-bakelite switches and scientific porcelain dishes;
D. transfer molding die-integrated circuit product;
E. Extrusion molding dies-rubber hose and plastic bag;
F, a thermoforming mold-a transparent molded packaging shell;
G. rotational molding model-soft rubber doll toy. ?
