[0002] The die lip is a mold used to produce plastic preforms. In order to ensure that the die lip has a high yield rate when it is used to produce plastic preforms, its processing accuracy is high. The groove width of the support ring inside the die lip / Groove depth ≤ 1 / 5, it is difficult to process it by ordinary machining methods, so in the existing production methods, EDM is usually used to process the support ring, the efficiency of EDM is low, and it takes 2- It takes 3.5 hours to complete the forming process of a support ring, which is difficult to produce in large quantities, and the electrode price of EDM is relatively high, resulting in high processing cost of the die lip

Embodiment 1
[0043] The angle between the rake face 1212 and the flank face of the turning tool 1 is 12°;
[0044] First fix the die lip 2 blank on the three-jaw chuck of the lathe, and then perform semi-finishing on the outer surface of the round platform part 21; after the semi-finishing is completed, remove the die lip 2 from the lathe, and then fix it on the lathe On the finish turning jig, finish the finish turning installation hole 221 on the fixed part; after the finish turning installation hole 221 is completed, remove the die lip 2 from the finish turning fixture, then fix it on the wire cutting jig, and use the wire cutting to cut the die lip 2. Cut it in half, so that the die lip 2 is divided into a left die and a right die; Put the left and right molds into the quenching tank in the cooling chamber of the vacuum furnace for quenching to improve the surface hardness and smoothness of the left and right molds; fix the left and right molds on the bed , carry out fine grinding on ...
