Frequency hopping radio station aluminum alloy shell extrusion molding dies

Abstract

The invention relates to an extrusion forming mould of frequency-modulation radio station aluminum alloy hull, which is a diverting split-ring mould of twelve channels. The invention comprises the following settings: mold core 2 being divided into twelve septums with dovetail groove 8 used to plug connecting block in; cope pattern 1 equipping external diverting hole; connection of external diverting hole and mould core 2 carrying on endless belt 6 with slope equipping guiding groove 7; opposite sides of cope pattern equipping internal diverting hole 4; and middle die 9 equipping welding chamber and ring-shaped impediment wall. The invention has the advantages of simple structure, high-quality product, changeable fixing dimension and low cost.

Description

Technical field: [0001] The invention belongs to the category of moulds, in particular to an extrusion molding die for an aluminum alloy shell of a frequency hopping radio station formed by one extrusion. Background technique: [0002] As we all know, the aluminum alloy casing of the FM radio station used to load the communication circuit board on the transmitter, due to its complex cross-sectional shape, the size of the internal channel and the thickness of the rib plate are not equal, especially the thickness of the rib plate is only 0.8-1.5mm, and it is asymmetrical. Therefore, the traditional precision casting process is often used, but it needs to use three sets of molds to prepare a set of sand molds, and the service life of a set of sand molds is short. It can only be cast into one product, so the productivity is low. In addition, the casting process itself is inherently The defects seriously affect the performance of the product. At the same time, the size of the pro...

[0002] As we all know, the aluminum alloy casing of the FM radio station used to load the communication circuit board on the transmitter, due to its complex cross-sectional shape, the size of the internal channel and the thickness of the rib plate are not equal, especially the thickness of the rib plate is only 0.8-1.5mm, and it is asymmetrical. Therefore, the traditional precision casting process is often used, but it needs to use three sets of molds to prepare a set of sand molds, and the service life of a set of sand molds is short. It can only be cast into one product, so the productivity is low. In addition, the casting process itself is inherently Defects seriously affect the performance of the product. At the same time, the dimensions of the products cast each time cannot be completely consistent, so the interchangeability is poor.
