Automatic wax injection press

Abstract

The invention relates to an automatic wax injection press which is particularly used for automatic production of wax patterns, and belongs to the technical field of precision investment casting pattern making. The automatic wax injection press mainly comprises an electric cabinet, a reinforcing plate, a wax injection press cover plate, support pillars, an upper working table, a first magnetic sucking disc, an upper transitional plate, an upper die, a lower die, a lower transitional plate, a second magnetic sucking disc, a wax injection press seat, a magnetic sucking disc mounting board, an oil cylinder and a piston rod, wherein the lower transitional plate is magnetically adsorbed on the second magnetic sucking disc; the lower die is fixedly connected onto the lower transitional plate; the upper die is positioned on the lower die; a gate stick is connected to one side of the upper die and that of the lower die; the upper die is fixedly connected onto the upper transitional plate; and the upper transitional plate is magnetically adsorbed on the first magnetic sucking disc. The automatic wax injection press has the advantages as follows: the structure is simple, compact and reasonable; the automatic production of the wax patterns reduces the labor intensity of workers and improves work efficiency; the quality of the produced wax patterns is stable; and the die changing is fast, and the service lives of the dies are long.

Description

technical field [0001] The invention relates to an automatic wax pressing machine, specifically for automatic production of wax patterns, and belongs to the technical field of investment casting and precision casting. Background technique [0002] With the development of investment casting, many large thin-walled casings and engine structural parts in aerospace and aviation are produced by investment casting technology. In the early days, forgings and castings were generally used, and they were composed of riveting or welding after machining. Now, investment casting is used for one-time integral casting, which not only reduces material consumption, but also simplifies the process, saves man-hours, and the economic benefits are very obvious. However, there are still a series of technical difficulties in the whole casting process, such as pressing wax, pouring one-time forming and so on. [0003] The commonly used means of pressing wax at present is to adopt aluminum mould, ...

AI Technical Summary

Problems solved by technology

After long-term use, the mold will be worn to varying degrees, so there will be flashes, wax leakage and other phenomena, which directly affect the quality of the product

The production efficiency of manual wax pressing method is low, and the labor intensity of workers is high
