Chromium plating device for front machine barrel of injection molding machine

Abstract

The invention discloses a chromium plating device for a front machine barrel of an injection molding machine. The problems that in the prior art, a chromium plating device for a front machine barrel is low in production efficiency and high in rework rate, and an anode needs to be replaced frequently are solved. The chromium plating device for the front machine barrel of the injection molding machine comprises a conductive mechanism, an anode positioning plate, a workpiece positioning plate, workpieces and anodes, wherein a plurality of anodes and a plurality of workpieces are arranged, so thatthe plurality of workpieces can be simultaneously processed by utilizing a positive electrode plate and a negative electrode plate; the working efficiency can be greatly improved; meanwhile, the anodes are made by lead-tin welding; lead is arranged on the surfaces of the anodes, so that the anodes can be well prevented from being dissolved in electrolyte; the anodes can be protected, electrolytepollution can be avoided, the anodes and through holes of the front machine barrel of the injection molding machine are coaxially arranged, the uniformity of a plating layer is guaranteed, the water passing structure is arranged below the workpiece positioning plate, circulation of electrolyte can be enhanced through the water passing structure, and the glossiness of the plating layer of the frontmachine barrel of the injection molding machine is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of chrome plating of the front barrel of an injection molding machine, in particular to a chrome plating device for the front barrel of an injection molding machine. Background technique [0002] In the current processing process, due to the high working strength of the front barrel of the injection molding machine, its material requirements are very high. The front barrel needs to be chrome-plated to enhance its hardness, heat resistance, wear resistance and chemical properties, so that It is not easy to be damaged during use and does not require frequent replacement of the front barrel. In order to chrome the front barrel of the injection molding machine, in the production process, iron wire is generally used to make the anode, and the anode is hung above the barrel. The rack plating in the industry is basically a single hanger, the production efficiency is relatively low, and rework The rate is extremely high...

AI Technical Summary

Problems solved by technology

In order to chrome-plate the front barrel of the injection molding machine, iron wires are generally used to make anodes during the production process, and the anodes are hung above the barrel. Hanging plating in the industry is basically a single hanger, and the production efficiency is relatively low. Rework The rate is extremely high, and because the iron wire is easy to decompose in the electrolyte, it is easy to pollute the electrolyte, and the anode needs to be replaced frequently
