To achieve these goals, the present invention adopts following technical scheme: a kind of preparation method of runner of injection mold, comprises the steps:
Step one: get the raw materials ready by a full circle part, on full circle part, roughing goes out endoporus, cylindrical and left and right both ends of the surface, forms domain part; Then domain part is carried out quenching heat treatment;
Step 2: the left and right end face of semifinishing domain part, cylindrical and endoporus, mounting plane; On domain part, roughing goes out running channel, fusion chamber; On domain part, roughing goes out pin-and-hole, screw hole and screwed hole, then domain part is carried out artificial aging heat treatment;
Step 3: the left and right both ends of the surface of fine finishining domain part, ensures that the depth of parallelism of the left and right end face of domain part is within 0.02mm; Fine finishining endoporus, fusion chamber and running channel, process flow passage chamber, and then the left and right end face of fine finishining domain part, ensures that the depth of parallelism of the left and right end face of domain part is within 0.02mm; Pin hole processing, ensures that the interval error of all pin-and-holes is between-0.01 ~ 0.01mm; Polishing running channel, flow passage chamber and fusion chamber, make its luminosity reach Ra0.4mm; Now the machining of runner of injection mold.
Beneficial effect of the present invention:
The preparation method of the runner of injection mold of the present invention, the method fabrication cycle is short, injection molding product precision is high, the production of the line that can again resume production, and often recovers the fund that a production line can save nearly ten million yuan.
