Embodiment Construction

[0018] The following describes the embodiments of the present invention in detail.

[0019] The invention provides a method for repairing a mould, the method comprising the following steps:

[0020] a1. Measure the size of pits, pits and lack of material on the bottom surface of the cavity to the parting surface;

[0021] a2. Compare the measured size with the standard size, and calculate the size difference. If it is within the standard size tolerance, it is qualified; if it exceeds the marked size tolerance, it is unqualified;

[0022] a3. Repair the mold according to the size:

[0023] b1. The size is qualified: the bottom surface of the cavity is ground to eliminate defects;

[0024] b2. The difference is less than 0.1mm: Grinding the bottom surface of the cavity, the parting surface and the surface based on the parting surface, the grinding size is equal to the calculation result;

[0025] b3. The difference is greater than 0.1mm: The pits, pits and missing materials a...

Abstract

The invention provides a mold repairing method. The method comprises the steps that a1 the size of a hard spot, a pit and a missing material on the bottom of a cavity to a parting surface is measured;a2 the measured size is compared with the standard size; the size difference is calculated; if the size difference is in the standard size tolerance, the size is qualified; if the size difference exceeds the standard size tolerance, the size is unqualified; and a3 a mold is repaired according to the size difference. The method further comprises the steps that b1 if the size is qualified, the bottom of the cavity is ground to eliminate defects; b2 if the difference is less than 0.1 mm, the bottom of the cavity, the parting surface and a surface with the parting surface as the measurement reference are ground, wherein the grinding size is larger than the calculated result; b3 if the difference is greater than 0.1 mm, a device is used to carry out material spraying on the hard spot, the pit and the missing material, and the height exceeds the bottom of the cavity; and a4 calibration measurement and polishing are carried out. The mold repairing method provided by the invention has the advantages of simple and clear operation, high repair efficiency and good effect.

Description

technical field [0001] The invention relates to a repair method, in particular to a method for repairing a mould. Background technique [0002] Due to the complex mold manufacturing process, long production cycle, and high processing costs, especially the high processing costs for precision and complex molds or large-scale molds, for example, FAW spends tens of millions of dollars on mold manufacturing and maintenance every year. If the mold fails early, it will cause significant economic losses to the enterprise. Therefore, it is very important to repair the failed mold and restore its performance and put it back into use to achieve the purpose of prolonging the service life of the mold, reducing costs and improving economic benefits. Contents of the invention [0003] 【1】Technical problems to be solved [0004] The technical problem to be solved by the present invention is to provide a method for repairing molds with high repair efficiency and good effect. [0005] 【2...
