Abstract
 First wash to press a size accuracy for proceeds analysis, analyzing that spare parts to get to use the general accuracy to then satisfy the request of the spare parts accuracy, again from the spare parts's shape, size the mark note and produced the batch quantity etc. The circumstance to see, choose to hurtle the bore the project. Hurtle the compound mold inside of of bore in this design, not only want the consideration to make do to can satisfy the usage request, and still want the service life of the assurance molding tool. Should wash to cut the molding tool to return to in detail described the molding tool the type spare parts include the choice for craft for design for, cave template, convex template, convex mold fixing the plank, convex and cave mold fixing plank, ascending mold, next mold, unloading the plank, mold the handle waiting, important spare parts counting and calculation of last mold, and release the organization and design of construction other the process, and among them and inside also included: The craft analyzes, and the craft project really settle, calculation semi- finished product the size, painting row kind the diagram, calculation to wash the pressure, pressure machine of choice, calculation pressure center, design for total construction for choice for convex and cave mold cleft for circle Cape for calculation for semi- finished product size for calculation for size, craft the calculation washing cutting first piece calculation, wash the pressuring, convex mold and cave mold radius, washing cutting the mold the inside convexly, work size of cave mold, washing pressing the equipments, molding tool, main zero parts and choice of convex and cave mold blade,the molding tool manufacturing assemble the important point etc.
