A pressure device for the production of castings

Abstract

The invention relates to a pressure device for production of a casting. The pressure device comprises a primary base and secondary bases. The primary base is in a cuboid shape, and is made of stainless steel materials. The bottom of the primary base is bent outwards and fixed through bolts. The number of the secondary bases is two, the secondary bases are arranged on the two sides of the primary base, the primary base and the secondary bases are located on the same straight line, and the secondary bases are kept symmetrical about the primary base. The secondary bases are in a cuboid shape, the length of each secondary base is smaller than that of the primary base, and the bottom of each secondary base is bent outwards and fixed through bolts. A power assembly is arranged on the upper portion of the primary base, a first press mold assembly and a second press mold assembly are arranged on the two sides of the power assembly, and a first fixing assembly and a second fixing assembly are arranged on the upper portions of the secondary bases.

Description

technical field [0001] The invention relates to the field of casting production equipment, in particular to a pressure device for producing castings. Background technique [0002] Die casting is a fast-growing special casting method with less cutting and no cutting in modern metal processing technology. It is the process of filling the mold with molten metal at high pressure and high speed, and crystallizing and solidifying under high pressure to form a casting. High pressure and high speed are the main characteristics of die casting. The commonly used pressure is tens of MPa, and the filling speed is about 16-80 meters. / second, the time for the molten metal to fill the mold cavity is extremely short, about 0.01-0.2 seconds, because the products produced by this method have high production efficiency, simple process, high tolerance level of castings, good surface roughness, and high mechanical strength , can save a lot of mechanical processing procedures and equipment, save...

AI Technical Summary

Problems solved by technology

[0003] (1) The basic mode of using the pressure device is one person, one machine. The pressure device is manually operated to complete the extrusion of the casting. In the production process, the pressure device occupies a relatively large area, and the mode of one person, one machine reduces the utilization rate of labor ;

[0004] (2) The traditional pressure device adopts the form that a set of equipment is controlled by a set of control units, and each pressure device is an independent working unit. The production cost of such equipment is relatively high and the cost is too large;
