A monitoring method of mold cooling pipeline

Abstract

A method for monitoring a mold cooling duct (2), relating to the technical field of molds, and comprising the following steps: S1. introducing a cooling liquid of a specific pressure into an inlet (3) of a mold cooling duct (2) to be monitored; S2. acquiring a measured flow value, within a specified time, of the cooling liquid at an outlet (4) of the mold cooling duct (2) to be monitored; S3. repeating said steps S1 and S2 at least once, so as to obtain several measured flow values, and using an averaged value of the measured flow values as a measured flow value; and S4. determining, by comparing the monitored flow value with a standard flow value, whether the mold cooling duct (2) to be monitored is qualified. In this invention, after the cooling liquid of a set pressure is introduced into a mold cooling duct (2) to be monitored, several measured flow values within a certain time are acquired, an averaged value of the measured flow values is used as a monitored flow value, and the monitored flow value is compared with the standard flow value, thereby quickly determining, in cases where the internal parts of the mold are not visible, whether the mold cooling duct to be monitored is qualified.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a method for monitoring mold cooling pipelines. Background technique [0002] In the design of die-casting molds, the design of cooling pipes plays a vital role in the molding quality of products. If the cooling effect is not good, die-casting products are prone to shrinkage cavities, mold sticking to aluminum and other defects. To solve these problems, a reasonable mold cooling system design is the first condition. However, under the premise of a reasonable cooling system design, the processing conditions of the mold cooling pipeline and the installation level of the cooling parts will also have a huge impact on the cooling of the mold. . Nowadays, in order to achieve a good cooling effect for the cylinder block mold, the cooling system is very complicated.

[0002] In the design of die-casting molds, the design of cooling pipes plays a vital role in the molding quality of products. If the cooling effect is not good, die-casting products are prone to shrinkage cavities, mold sticking to aluminum and other defects.

To solve these problems, a reasonable mold cooling system design is the first condition. However, under the premise of a reasonable cooling system design, the processing conditions of the mold cooling pipeline and the installation level of the cooling parts will also have a huge impact on the cooling of the mold.

Nowadays, in order to achieve a good cooling effect for the cylinder block mold, the cooling system is very complicated. Sometimes the water delivery hole of the coolant has two angles at the same time, which adds a lot of difficulty to the processing. The case where the water hole processing is not connected
