The problem existing for prior art, the invention provides a kind of preparation method of runner of injection mold, the method fabrication cycle is short, injection molding product precision is high, the production of the line that can again resume production, and production line of every recovery can be saved the fund of nearly ten million yuan.
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 1: get the raw materials ready by a full circle part, roughing goes out endoporus, cylindrical and left and right both ends of the surface on full circle part, forms domain part; Then domain part is carried out to 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 to artificial aging heat treatment;
Step 3: the left and right both ends of the surface of fine finishining domain part, the depth of parallelism of the left and right end face of assurance 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, and the depth of parallelism of the left and right end face of assurance domain part is within 0.02mm; Pin hole processing, guarantees 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 runner of injection mold machines.
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, production line of every recovery can be saved the fund of nearly ten million yuan.
