Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to a concave-convex mold for an aluminum tube cable. Background Art

[0002] Aluminum tube cables require thin walls, only about 0.65 mm on one side, and the overall wall thickness difference should be controlled at about 0.1 mm. This requires the design of a suitable extrusion die, and the die design must accurately control the material flow to ensure that the final product size, shape and performance meet the requirements. Summary of the invention

[0003] This utility model hopes to provide a concave-convex mold for an aluminum tube cable, and the specific scheme is as follows:

[0004] A concave-convex mold for an aluminum tube cable comprises a convex film and a concave film, wherein the concave film comprises a mold body, the interior of the mold body is a hollow circular hole, and the mold body comprises a first drainage surface, a drainage arc surface, a drainage inclined surface and a second drainage surface.

[0005] Tungsten steel is provided on the convex film and the concave film.

[0006] The length of the first drainage surface is equal to the length of the second drainage surface.

[0007] The thickness of the first drainage surface plus 1 mm is equal to the thickness of the second drainage surface.

[0008] The length of the drainage arc surface is equal to 1 / 2 of the diameter of the hollow circular hole.

[0009] The length of the drainage slope is equal to 1 / 4 of the diameter of the hollow circular hole.

[0010] The difference between the diameter of the hollow circular hole and the outer diameter of the top of the convex membrane is 1.3 mm.

[0011] The utility model ensures that the aluminum rod material enters the cavity through the high and low design and the arc inclined surface design, and balances the filler through the high and low surfaces of the die, thereby controlling the flow rate and preventing the flow imbalance and flow rate from affecting the quality of the aluminum tube product. The mold also uses the middle tungsten steel material, which can not only make the wall thickness more accurate, but also increase the service life of the mold. The overall life can be increased by about 10 times by using the tungsten steel material. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] A concave-convex mold for an aluminum tube cable comprises a convex film 1 and a concave film 2, with a semi-molten aluminum material 3 located between the convex film 1 and the concave film 2; the concave film 2 comprises a mold body 5, the interior of the mold body 5 is a hollow circular hole 6, and the mold body 5 comprises a first drainage surface 7, a drainage arc surface 8, a drainage inclined surface 9 and a second drainage surface 10.

[0016] Tungsten steel 4 is provided on both the convex film 1 and the concave film 2.

[0017] The length L1 of the first flow guiding surface 7 is equal to the length L2 of the second flow guiding surface 10 .

[0018] The thickness H1 of the first drainage surface 7 plus 1 mm is equal to the thickness H2 of the second drainage surface 10 .

[0019] The length L3 of the drainage arc surface 8 is equal to 1 / 2 of the diameter D1 of the hollow circular hole 6 .

[0020] The length L4 of the drainage slope 9 is equal to 1 / 4 of the diameter D1 of the hollow circular hole 6 .

[0021] The difference between the diameter D1 of the hollow circular hole 6 and the outer diameter D2 of the top of the convex membrane 1 is 1.3 mm.

[0022] Aluminum tube cable extrusion is an aluminum product processing technology. Its working principle is: put the concave film 2 and the convex film 1 into the cavity, tighten the two sides with nuts, and the concave film 2 and the convex film 1 cannot be loose. The aluminum rod is sent to the preheated cavity through the rotation of the extrusion wheel and extruded inside. The extrusion process will generate a very high temperature. The aluminum rod is in a semi-molten state and distributed on the surface of the convex die 1. Through the designed concave die drainage surface, it is evenly extruded from the gap between the concave film 2 and the convex film 1 to form an extruded material of the required size, and then coated on the core wire.

[0023] The mold design must accurately control the material flow to ensure that the size, shape and performance of the final product meet the requirements. We have designed multiple drainage surfaces of the concave mold from many aspects. During the extrusion process, the semi-molten aluminum material 3 flows from the first drainage surface 7 and the second drainage surface 10 on both sides to the drainage slope 9 and the drainage arc surface 8, and finally extrude through the gap between the concave film 2 and the convex film 1.

[0024] The above description is not a limitation of the design of the utility model, and the design of the utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the design of the utility model also fall within the protection scope of the design of the utility model.
