Novel casting system of die-casting die for large 5G communication radiator part

Abstract

The invention provides a novel casting system of a die-casting die for a large 5G communication radiator part. Flow guide ribs are arranged on the edges of the preset shapes of fins, and the flow guide ribs are partially removed after machining is completed, so that the stability in flowing and filling of molten aluminum in the die-casting process is achieved, the reject ratio of castings is reduced, the filling speed is reduced, and the service life of the die is prolonged. The novel casting system of the die-casting die for the large 5G communication radiator part comprises a movable die part and a fixed die part, wherein a movable die core is arranged in the center area, facing the fixed die part, of the movable die part; a fixed die core is arranged in the center area, facing the movable die core, of the fixed mold part; a cavity is formed between the movable die core and the fixed die core in a combined mode; a plurality of fin cavity areas are arranged at a feeding port of the cavity; a flow guide rib cavity area is arranged at the corresponding position, facing the feeding port, of each fin cavity area; and each flow guide rib cavity area is of an arc flow guide structure gradually flaring from the feeding port to the designed end face of the corresponding fin.

Description

technical field [0001] The invention relates to the technical field of die-casting molds, in particular to a new casting system for die-casting molds of large-scale 5G communication radiator parts. Background technique [0002] In the communication industry, die-casting products are mainly structural parts of equipment, such as base station filter housings, cover plates, etc. With the advent of 5G, a new architecture of the wireless access network has been introduced, and the base station structure has greatly increased in terms of volume, weight, and power consumption, which is about three times that of 4G. In order to pursue better heat dissipation, die castings gradually tend to be large-scale integrated and lightweight, so the dimensions of die-casting products are getting larger and larger, and the height of heat sinks for radiator parts is also getting higher and higher. Traditional die-casting casting The system has been difficult to meet the product molding requirem...

In order to pursue better heat dissipation, die castings gradually tend to be large-scale integrated and lightweight, so the dimensions of die-casting products are getting larger and larger, and the height of heat sinks for radiator parts is also getting higher and higher. Traditional die-casting casting The system has been difficult to meet the product molding requirements, and the problem of cold insulation of heat sinks is prone to occur
