接着上面的,一次输不完the cavity and or core block can be removed from the parting line of the tool without removing the mold from the press. To accomplish this it requires less clearance in the support plate so that the ejector pins retain alignment once the cavity block is removed.The ejector pin holes will require a gradual transition from a clearance diameter in the rear of the block to a tight fit at the front of the block. This is most often accomplished with a double pass wire edm process, one pass cuts the taper for clearance and the second cut finishes the fit diameter for a length of 2-3 times the ejector pin diameter. The cavity and core blocks also require bolts that are accessible from the parting line and usually also have a jack screw thread machined into the bolt clearance diameter so that smaller bolts can be used to jack the cavity block out of a pocket.
