Abstract
The invention relates to a method for processing a locating hole of a product locating piece in a forming mould, relating to the technical field of processing of locating holes of product locating pieces in forming moulds. The method comprises the following steps of: manufacturing a small hole which is smaller than a final hole at the approximate position of the locating piece; manufacturing a step pin and pressing the step pin in the locating hole of a mould body; fixing the locating piece at the correct position by utilizing a connecting piece; filling epoxy resin mixed glue in the gap between the locating piece and the step pin; after a colloid is thoroughly dried, taking down the locating piece; centring the hole moulded by the mixed glue; and expanding the hole to form the required locating hole. According to the method for processing the locating hole of the product locating piece in the forming mould disclosed by the invention, the locating hole position of the locating piece to be repaired is taken out from the mould body; simultaneously, the bottom hole of the mould body cannot be damaged; the mould is prevented from being returned and processed again; the repairing time of the mould is shortened; and the labour production efficiency is increased.
Description
Technical field
The present invention relates to the processing technique field of product orientation part locating hole in the shaping mould.
Background technology
At present a lot of shaping moulds use owing to long-term, the locating hole of product orientation part, installing hole and locating surface, and major part is is all worn and torn, needs to change keeper.In order to guarantee the air-tightness of die body, the locating hole of forming panel one side must adopt the blind hole form during fabrication.Because product is often changed; So these keepers also often need to make again, forming panel one side major part all is the hyperboloid structure, and originally making is also all to be that employing loft, model are foundation; So locating hole of the keeper of making again; Can't with original die body harmonious (concentric), can't guarantee the instructions for use of product, how locating hole being returned on the keeper and do not injure the die body profile is a sizable difficult problem.
The method that generally adopts at present is: foramen primum is abandoned again made locating hole simultaneously with keeper, after changing so several times, reprocessing, die body has been riddled with gaping wounds, and die body is just had no alternative but to comply and newly processed like this.So not only cause unnecessary waste, also prolonged reprocessing the time of mould.
Summary of the invention
The objective of the invention is:
The purpose of this invention is to provide a kind of method, can under the situation of not destroying die body, the position of positioning hole in the die body be returned throwing on keeper, simultaneously, the present invention can reduce mould and repeat processing, shortens reprocessing the time of mould, raises labour productivity.
Technical scheme of the present invention is:
The invention provides and a kind ofly be used for quick, safe locating hole and return the method for throwing on keeper die body.This method may further comprise the steps:
The first step has been made the keeper profile by loft, model;
In second step, keeper is pre-installed in moulding die body relevant position, and corresponding locating hole Position Approximate groove throwing is drawn on the keeper;
The 3rd step, by the scribing position system of on keeper, boring than the final bore dia switching hole of 5mm extremely when young;
The 4th step, make a positioning step pin, a side external diameter is located the aperture for excessively to cooperate with die body, and the external diameter of opposite side is than the bore dia 6mm extremely when young that transfers;
In the 5th step, be coated with lubricating oil in non-die body one side that is pressed into of step pin;
The 6th step was pressed into die body with the step pin, keeper was fixed on the die body by the tram again;
The 7th step, filling epoxy resin epoxy glue between keeper and step pin;
The 8th the step, treat the glue finish-drying after, keeper is taken off, look for the center of circle by the locating hole of epoxy glue institute moulding, and final hole expanded as in the hole.
Advantage of the present invention is:
The position of positioning hole of the keeper that the present invention can be fast reprocesses needs is taken out from die body, can not destroy the bottom outlet of die body simultaneously, avoids mould from newly returning processing, has shortened reprocessing the time of mould, has improved labor productivity.
Description of drawings
Sketch map when accompanying drawing 1 is implemented for this method, wherein, 1 is the ladder pin, and 2 is epoxy resin mixed glue, and 3 is keeper, and 4 is die body.
The specific embodiment
The specific embodiment of this method is: elder generation is with aperture less than whole hole of about position system of keeper; Make a ladder pin then and be pressed in the die body locating hole, utilize connector to be fixed on the tram keeper then, be filled in the gap between keeper and the ladder pin to epoxy resin mixed glue again; After treating that colloid thoroughly parches; Keeper is taken off, the hole centering of moulding out by epoxy glue again, expanding boring is required locating hole.Require used pin and cooperating of die body locating hole excessively to cooperate, epoxy glue must be filled full.
An embodiment of this method is following: like the manufacturing process of certain type gusset keeper, keeper profile thickness 16mm width 45mm length 120mm has two D20H7 holes with moulding die body location, and corresponding locating hole is D10H7 on the die body.Its localization method may further comprise the steps:
The first step has been made the keeper profile by loft, model;
In second step, keeper is pre-installed in moulding die body relevant position, and corresponding locating hole Position Approximate throwing is drawn on the keeper;
In the 3rd step, bore system D15 hole by scribing position;
The 4th step: make a positioning step pin, a side external diameter is D10r6, and opposite side is D8h7;
The 5th step: be coated with lubricating oil in step pin D8h7 one side;
The 6th step: the step pin is pressed into die body, again keeper is fixed on the die body by the tram;
The 7th step: filling epoxy resin epoxy glue between keeper and step pin;
The 8th step: after treating the glue finish-drying, keeper is taken off, look for the center of circle, and the D20H7 hole is expanded as in the hole by the D8h7 hole.
