For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of extrusion die of shaped material of radiator comprises water conservancy diversion template and die main body, and the water conservancy diversion template is fixed in die main body fixes, the first half of water conservancy diversion template is provided with a plurality of pod apertures, pod apertures is evenly distributed, the latter half of weldering and the chamber of being provided with of water conservancy diversion template, and each pod apertures is communicated with weldering and chamber respectively.
Described pod apertures is a fan shape, and pod apertures is circular arrangement, and pod apertures is arranged in the border circular areas, and the top of pod apertures refers to the geometric center of border circular areas.
Described pod apertures is a fan shape, and pod apertures circular array, pod apertures are arranged in the elliptical region, and the top of pod apertures refers to the geometric center of elliptical region.
Also comprise a center pod apertures that is arranged on geometric center on the described water conservancy diversion template, the center pod apertures is a manhole, and the center pod apertures is communicated with weldering and chamber.
The position that pod apertures and weldering and chamber join is provided with the transition inclined-plane.
The quantity of described pod apertures is 4 or 6.
Die main body is provided with the squeeze film die cavity, and the gross area in the plane of structure cross section of pod apertures and center pod apertures is greater than the gross area of the lateral cross section of squeeze film die cavity.
The beneficial effects of the utility model: the utility model comprises water conservancy diversion template and die main body, the water conservancy diversion template is fixed in die main body, the first half of water conservancy diversion template is provided with a plurality of pod apertures, pod apertures is evenly distributed, the latter half of weldering and the chamber of being provided with of water conservancy diversion template, each pod apertures is communicated with weldering and chamber respectively.Design by the water conservancy diversion template, by pod apertures the materials flow of extrusion die is divided into multiply, each burst materials flow converges the middle part solid part that is fused into shaped material of radiator again in weldering and chamber, when producing radiator, each position uniformity of temperature profile of the middle part solid part of shaped material of radiator, the middle part solid part conjugation height of shaped material of radiator, the middle part solid part of shaped material of radiator is difficult for splitting, effectively control the length of the tail that contracts of the section bar that extrusion die bore simultaneously, the length of tail of will contracting drops to minimum, the quality of the radiator that assurance processes improves yield of products.
