Cold-chamber die casting machine

Abstract

The invention discloses a cold-chamber die casting machine which comprises a machine seat, a first mounting frame, a second mounting frame, guiding columns, sliding rails, a transverse-moving slidingplate, sliding sleeves, a squeezing cavity, a die casting air cylinder, a concave die plate, a liquid inlet pipe, a supercharging piston, a liquid inlet pipe orifice, a material filling hole, a convexdie block, an ejecting air cylinder, a positioning partition plate, an ejecting plate, a convex die main body plate, through holes, ejecting pins, sealing vales, a high-pressure air pump, a cooler and a concave surface plate. The cold-chamber die casting machine disclosed by the invention is compact in structure and convenient to use; by adoption of the structural design that an ejecting device is additionally arranged on the convex die plate, a casting can be directly ejected, the trouble that the casting needs to be directly taken by people out of a die can be avoided, the die casting efficiency can be improved, and the personal safety of an operating worker can be guaranteed; through high-pressure cooling airflow jetted from air ports of the ejecting pins, a finished workpiece can be quickly cooled, the cooling speed in a die casting process of the workpiece can be improved, and the more uniform cooling effect can be achieved; and meanwhile, waste scraps on the workpiece can be effectively removed and the quality of a finished die casting product can be improved.

Description

technical field [0001] The invention relates to the technical field of die-casting machines, in particular to a cold-chamber die-casting machine. Background technique: [0002] The die-casting machine is a series of industrial casting machines that hydraulically inject molten metal into the mold under pressure to cool and form it, and obtain solid metal castings after the mold is opened. It was originally used for die-casting characters. With the advancement of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles, and household appliances, die-casting technology has developed extremely rapidly in various aspects. Die-casting machines are divided into hot-press chamber die-casting machines and cold-press There are two types of chamber die-casting machines.

With the advancement of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles, and household appliances, die-casting technology has developed extremely rapidly in various aspects. Die-casting machines are divided into hot-press chamber die-casting machines and cold-press There are two types of chamber die-casting machines. Most of the existing cold die-casting machines use natural cooling to cool the castings. This cooling method takes too long, slows down the manufacturing speed of castings, and greatly reduces production efficiency. At the same time, die-casting After forming, workers need to go deep into the mold to take out the casting, so sometimes the temperature of the finished product may not be completely reduced to a harmless level, which will cause damage to the operator's body, and it is very difficult to take out the casting directly from the mold
