Scale stripping device for mold cooling pipe wall

Abstract

The invention discloses a mold cooling pipe wall limescale peeling device. The mold cooling pipe wall limescale peeling device can go deep step by step along a cooling pipe to peel off limescale on apipe wall with double-helix gap rinsing in cooperation. The mold cooling pipe wall limescale peeling device is characterized in that a connecting sleeve is arranged in a communicating hose in a sleeved manner, and is fastened by a buckle in a sealed manner, a plurality of antiskid protrusions are arranged on the outer wall of the communicating hose at equal intervals, more than one antiskid protrusion is arranged as one group, the antiskid protrusions are distributed on the outer wall of the communicating hose as segments, the multiple antiskid protrusions of the same group are distributed inthe circumferential direction, the separation distance between every two adjacent antiskid protrusions is the same, a ferrule is inlaid into the connecting sleeve, a plurality of rotary blades are arranged at the bottom of the ferrule, the ferrule rotates freely relative to the connecting sleeve, a rotary ring is arranged between the ferrule and the connecting sleeve, one end of a peeling pipe isfixedly arranged on the ferrule, the peeling pipe communicates with the communicating hose, a spiral groove is formed in the outer wall of the peeling pipe, and the diameter of the peeling pipe gradually decreases from one end to the other.

Description

Technical field[0001]The invention provides a device for peeling off scale on the wall of a mold cooling pipeline, which relates to a device for peeling off scale on a cooling pipeline of a mold located in a module during mold maintenance, and belongs to the field of mold maintenance. In particular, it relates to a device which can gradually deepen along the cooling pipeline and cooperate with double spiral gap flushing to strip the scale on the pipeline wall.Background technique[0002]At present, in the process of mechanical production, many products are made by molds. For example, plastic products are mostly made of injection molds and blow molds; metal materials are molded by die-casting molds. Because of the mold temperature control in order to ensure fluidity during molding, the mold needs to be controlled.

Problems solved by technology

[0002] At present, in the process of mechanical production, many products are molded by molds. For example, plastic products are mostly molded by injection molds and blow molds; metal materials are molded by die-casting molds. In order to ensure fluidity during molding, molds need to be controlled for mold temperature. For high temperature points, the cooling system is usually used for cooling. Through the built-in water circuit circulation, the temperature is gradually controlled. During use, the water in the cooling water circuit is in contact with the pipeline. As the temperature increases, the water quality will produce scale in the pipe wall. , affecting the passage of cooling water, reducing the temperature exchange efficiency and causing the local temperature of the mold to be too high. Therefore, it is necessary to regularly clean and dredge the cooling water. In the waterway, soak the cooling waterway, and then perform impact cleaning with high pressure to clean the scale in and out. However, the waterways in the module are criss-crossed. When high-pressure cleaning is performed, it is easy to accumulate at the intersection of the pipelines, making the cleaning incomplete. And the weak acid soaks for a long time. When the water pipe is blocked, the acid solution cannot circulate, and the high-pressure cleaning cannot wash out the large scale. The large scale will be stuck in the water pipe. The cleaning is not thorough and the efficiency is low.

[0003] Publication number CN203246027U discloses a waterway automatic cleaning device for injection molds, including injection molds, connecting water pipes, anti-corrosion pumps, cleaning liquid pools, and cleaning liquids. The injection molds are connected to the cleaning liquid pools through water pipes, and the cleaning liquid pools are connected to anti-corrosion pumps through water pipes. , the anti-corrosion pump is connected to the injection mold through a water pipe, and the cleaning liquid pool is provided with a cleaning liquid. By connecting the cleaning liquid and the mold water path to form a circulation path, the mold water path is cleaned. This method is inefficient and requires continuous circulation. When the water path After clogging, it is difficult to form a circulation, and the cleaning effect is poor
