Embedment technology of section extruding structure and pressure casting structure of dense blades

Abstract

The invention relates to the field of manufacturing technologies for products such as heat radiators, and discloses an embedment technology of a section extruding structure and a pressure casting structure of dense blades. The technology comprises the following steps that firstly, a section extruding piece is manufactured; secondly, a pressure casting face is machined; thirdly, a pressure casting mold is designed; fourthly, the pressure casting mold is manufactured; and fifthly, in-mold pressure casting is carried out. The work efficiency of products manufactured through the technology is high, production in an assembly line scale manner can be achieved, and the machining amount is small, so that the embedment technology is completed, the reject ratio of the products is low, and meanwhile the production cost is reduced. Meanwhile, later CNC machining procedures can be reduced, high stability is achieved after the products are directly embedded, the overall structural strength is higher, and the service life of the products is longer. The products manufactured through the embedment technology are good in attachment performance and sealing performance, the section extruding structure and the pressure casting structure are perfectly embedded, good heat conduction capacity is achieved after embedment, the enough heat radiation area is achieved, and therefore the products overall have good heat radiation performance.

Description

technical field [0001] The invention relates to the field of manufacturing technology of radiator products, in particular to the fitting technology of dense blade extruded profile structure and die-casting structure. Background technique [0002] The main body of the heat sink needs to increase the heat dissipation area as much as possible and reduce the material consumption, so it is necessary to produce heat sinks that are as dense, thin, and long as possible, and the working environment for making such heat sinks is harsh. At present, there are three traditional methods of manufacturing this radiator: 1) die-casting; 2) extrusion; 3) extrusion assembly die-casting. However, using traditional technology to manufacture this kind of heat sink will have the following defects: 1) die-casting cannot realize the formation of slender and dense blades, and at the same time, the product quality rate after die-casting is low, and the heat dissipation effect is also poor; Make a str...

However, using traditional technology to manufacture this kind of heat sink will have the following defects: 1) die-casting cannot realize the formation of slender and dense blades, and at the same time, the product quality rate after die-casting is low, and the heat dissipation effect is also poor; Make a structure with a fixed and regular shape. If you make a complex inner cavity structure, all of it needs to be processed by CNC in the later stage. The processing volume is large, the production capacity is low, and there is a lot of waste of materials; 3) The extrusion assembly die-casting structure is not strong enough and the sealing is not good , poor thermal conductivity and life
