A processing technology of cast iron-nickel alloy spraying mold

Abstract

The invention discloses a cast iron-nickel alloy spraying mold processing technology, including mold raw material blanking—forging forming—tempering—rough grinding—mold surface spray welding—mold quenching—mold annealing—abrasive tempering—fine grinding and polishing— For the mold inspection process steps, first determine the size of the mold to be processed, select T10A as the steel for the blanking mold, and obtain the module blank by forging for blank making. The polishing equipment is equipped with an oilstone polishing disc and an ultrasonic polishing machine body, which can continue to complete the fine polishing operation after the rough polishing operation, without the need to replace the equipment. It is equipped with a concave fixed groove to cooperate with the first extrusion screw and the second extrusion screw. The mold can be better fixed during the fine polishing process to ensure the stability of the mold during fine polishing. A shaped heating bracket and a bottom heating tube are installed in the quenching furnace to solve the problem of inconvenient cleaning of the bottom of the mold during quenching. The problem of heating speeds up the temperature of the mold and saves the time of quenching.

Description

technical field [0001] The invention relates to the field of mold processing technology, in particular to a processing technology of cast iron-nickel alloy spraying mold. Background technique [0002] A mold is a tool that makes a blank into a workpiece with a specific shape and size under the action of an external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, as well as compression molding or injection molding of engineering plastics, rubber, ceramics and other products. There are various types of molds. It generally includes two parts, the movable mold and the fixed mold. Through the mutual cooperation of the fixed mold and the movable mold, the forming and removal of the workpiece can be completed. When the fixed mold and the movable mold are separated, the workpiece can be taken out. When the fixed mold and the movable mold are closed The blank is injected into the mold cavity to form. The...

Problems solved by technology

[0003] However, there are certain disadvantages in the existing mold processing technology. During the mold quenching process, the mold is placed on the bracket inside the quenching furnace, which will cause the bottom of the mold to be heated unevenly during heating. The way of heat conduction is used to balance the temperature of the mold body and the bottom of the mold, and the bottom of the mold cannot be heated, and in the steps of rough polishing and fine polishing, after rough polishing, it is necessary to replace the equipment for fine polishing of the mold, and after There is no good measure to fix the mold in the process of fine polishing, which will lead to errors in the process of fine polishing, which will affect the quality of the mold
