How does a typical mold company realize efficient mold quality inspection

With the development of the mold manufacturing industry, the development of mold measurement technology is also following each other. Different measuring technologies and different measuring equipment have emerged according to the different characteristics of mold manufacturing. From digital surveying and mapping involved in the initial stage of mold design, to mold processing procedure measurement, mold repair measurement, mold acceptance measurement and later mold repair measurement; from electronic small-size molds to large-scale automotive molds and large-scale aerospace industries For mold measurement, high-precision measurement equipment is everywhere. So far, the measuring equipment used in mold quality inspection not only includes the classic fixed high-precision coordinate measuring machine, but also because of the characteristics of mold manufacturing, various measuring equipment suitable for on-site application, such as portable articulated arm measuring machine, high-efficiency White light measuring machines, large-size laser trackers and other measuring equipment have also appeared in succession, and detection technologies such as contact and non-contact measurement, image and laser scanning, and photogrammetry are used to meet the inspection needs of mold products.

A typical mold company, in addition to the production and manufacturing of molds, will also involve the manufacture of some inspection tools, fixtures and ordinary machined parts. Under this circumstance, the fixed measuring machine with high precision, strong function and good versatility has become the classic measuring equipment of choice for the quality inspection of most mold companies.

The measurement requirements of the mold usually include the measurement of the designated point of the control profile, the diameter and position measurement of the assembly and positioning holes, etc., and often also require the profile of the measurement type and the surface profile. At this time, the high-precision, automation and point-to-point contact measurement capabilities of the stationary measuring machine are extremely suitable. If it is required to directly match the point cloud of the mold workpiece with the curved surface on the CAD model or perform the surveying and mapping of the mold part, the fixed measuring machine can also use a contact continuous scanning probe or a non-contact laser scanning probe to achieve high efficiency , High-density point cloud scanning measurement. It should be noted here that, because of the difference in measurement structure and measurement principle, the accuracy of contact measurement is usually better than that of non-contact measurement.

Quick response and rapid adjustment are an increasingly urgent development demand of mold companies in recent years. Through rapid mold manufacturing and delivery, the product launch cycle can be shortened, and valuable competitive opportunities can be won for enterprises. At the same time, the demand for large molds continues to expand. The subsequent online measurement and the on-site adjustment needs of molds, fixtures and inspection tools make The portable measurement system came into being.

Because of its portability and flexibility, the articulated arm coordinate measuring machine has gradually grown into one of the most important measurement equipment in the mold processing industry. The equipment can be used for online measurement in the workshop, and is not affected by the environment. It is convenient and quick to install. It can even be directly installed inside a large machine tool for on-line measurement of molds that have not been offline; at the same time, the measuring arm is made of carbon material , Very lightweight. When working, the operator holds the measuring arm to measure or survey the workpiece. The measuring direction can be adjusted at any time like a human arm, which largely avoids the existence of measuring blind spots. Therefore, the portable articulated arm measuring machine is one of the most efficient measuring equipment for surveying or measuring molds, and is especially suitable for non-batch single-piece measuring or surveying tasks.

With the continuous innovation and development of measurement technology, advanced measurement technology is not only reflected in the measurement room and manufacturing site, but also innovatively applied to machine tools and processing equipment. This is the on-machine measurement system we are talking about. As an effective process control method, in-machine measurement technology provides machine tool operators with real-time processing quality feedback, avoids unnecessary processing errors, and significantly improves the manufacturing efficiency of molds, especially large molds. On-machine measurement system includes workpiece on-machine measurement system and tool on-machine measurement system.
