With the development of modern industry, traditional manufacturing has been unable to meet the requirements of the mold, die CAE/CAD/CAM is a high-tech, high efficiency system engineering that transforms the way of manufacturing traditional mold. By using the Pro/E software which is based on the feature-based parameterized modeling, easy to use, feature-based parameterized modeling, unified database, all-associated system, powerful function. The modeling efficiency obviously surpasses the other traditional modeling methods. From design to manufacturing has been fully integrated, so it's a set of software that represents of CAE/CAD/CAM, and it's quite fit for design and machining of mold.

1. Plastic parts process analysis

The design of the product is a refrigerator ice box components used to make ice cubes. External dimensions of 270mm × 70mm × 70mm. Ice box has two rows of ten slots, has a printed arrow on the left side of the tendons, tendon of both sides of the groove can be controlled through the bars twist rotation of the ice box, right there is a slot, when the arrow goLock words, the slot structure of stuck in the refrigerator, ice box is locked out from the refrigerator, when the time slot and turn right out of the refrigerator structure, easy to remove the ice box.Thermostat can be when users need simple cleaning and cleaning of the demolition.Ice box material is polypropylene (PP), shrinkage was 1.5%.Technical requirements for plastic parts: the appearance is smooth, no glitches, cracks and other defects, safe and nontoxic.

2. Mold design based on Pro/Engineer

As the parts are smaller and larger production volume, from economic considerations, should be used more than one mold cavity.Also, because the structure of irregular parts and require side core, considering the complexity of the mold structure and manufacturing costs, and ultimately determine the mold cavity using a two-cavity mold.

The handle part of the product has a groove, in order to ensure the appearance of the product and a simple parting, the two grooves made into a hollow part of the slider, because one and two structural gap between the very few toneed to use a small cutter, which will reduce processing efficiency, ultrasonic cell disruption apparatus while the tool will increase the extent of damage.To do with the sub-surface volume is driving separate out these two as a single processing core set.So that is conducive to the accuracy of processing but also ensures that the local requirements, while saving costs and improving productivity.
