Cast iron nickel alloy spray mold processing technology

Abstract

The invention discloses a cast iron nickel alloy spray mold processing technology. The technology comprises the steps of mold raw material feeding, forging molding, annealing, rough grinding, mold surface spraying welding, mold quenching, mold annealing, grinding tool quenching and high-temperature tempering, fine grinding and polishing and mold detecting, wherein the dimension of a to-be-processed mold is firstly determined, T10A is selected as steel for a blanking die, and blank making is conducted through mold blank obtained through improved forging. A piece of polishing equipment is provided with an oilstone polishing disc and an ultrasonic polishing machine to complete fine polishing after rough polishing is completed, the replacement of the equipment is not needed, a concave fixing groove is formed to cooperate with a first squeezing screw rod and a second squeezing screw rod to achieve better fixing on the mold in the fine polishing process, the stability of fine polishing of the mold is ensured, a heating supporting frame and a bottom heating pipe are arranged in a quenching furnace to solve the problem of inconvenient heating on the bottom of the mold when quenching is conducted, the temperature increasing speed of the mold is accelerated, and quenching time is saved.

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
