Method for metal type cast radiator and mould

Abstract

The present invention discloses a method and metal mold for casting radiator, and features that the mold consists of side board, bottom board, sprue, clamping metal sheet, adjustable spacing strip, screw bolt, etc. The casting process includes the steps of setting radiating fins inside the clamping metal sheets, locking the side boards with the screw bolts, pouring high temperature aluminum liquid, cooling, demolding, and eliminating clamping metal sheets. By means of altering and replacing different mold parts, radiators of different types and sizes may be produced.

Description

Technical field:

[0001] The invention relates to a manufacturing method of a heat sink, in particular to a method and a mold for casting a heat sink with a metal mold. Background technique:

[0002] At present, most of the radiators on the market are molded at one time by die casting process. Due to the limitation of mechanical equipment and extrusion ratio, the ratio between the thickness, length, density and the overall length and width of the fins of the radiator is limited, which cannot meet the diverse needs of the market for the specifications of the radiator. Moreover, for the heat sink formed at one time, a set of molds can only press a product of one specification, and the remodeling period is long and the cost is high. There are also a small amount of radiators produced by melting and casting. The patent No. 97108973.6 is the invention of radiators. Its advantage is to meet the matching requirements of various lengths, widths, heights, and thicknesses, but there a...
