In order to ensure the normal operation of the cpu, the heat dissipation effect needs to be ensured. At present, a radiator manufactured by aluminum extrusion is generally used for radiating a central processing unit of a computer.

When aluminum extrusion is performed, the length of the spacer plate on the radiator is too long, which easily causes the spacer plate to bend, deform or break, thereby increasing the defective rate of finished products and damaging the die.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides an crowded type device of broach type heat dissipation section bar has solved the problem that the space bar is easily crooked, warp or cracked on the current radiator when processing.

Therefore, the utility model provides an crowded type device of broach type heat dissipation section bar, including last mould and with the lower mould that last mould matches, upward be provided with the feed port on the mould, the cross-section of feed port is "H" type, is provided with the nib that the position corresponds the feed port on the lower mould, and the nib includes a plurality of parallel arrangement's profile of tooth nib and T shape nib, and T shape nib transversely establishes between a plurality of profile of tooth nibs.

Furthermore, the middle pore canal of the feeding hole is pressed against the tooth-shaped die hole.

Furthermore, the bottom surface of the middle pore canal is provided with an inclined plane.

Furthermore, two first pin holes which are symmetrically arranged are formed in the surface of the upper die, and second pin holes corresponding to the first pin holes are formed in the lower die.

Furthermore, the upper die is provided with a hoisting hole.

Further, arc processing is carried out on the corners of the feeding holes.

The utility model provides a pair of crowded type device of broach type heat dissipation section bar when carrying out aluminium extrusion processing preparation broach type heat dissipation section bar, earlier through set up the locating pin in first pinhole and second pinhole, will go up the mould and assemble together with the lower mould. When carrying out aluminium extrusion processing, the feed port both ends of raw materials through last mould flow direction lower mould die hole, the feed port both ends of "H" type are wide, the centre is narrow, and feed port middle part feed rate slows down during the extrusion, and the raw materials flows to both sides wide portion, realizes evenly extruding. In addition, the middle pore canal of the feeding hole is abutted against the tooth-shaped die hole, so that sufficient feeding can be obtained at the narrow tooth-shaped die hole, and the quality of the formed partition plate is ensured. The circular arc treatment of the corner of the feed port avoids the slow discharge due to friction force, and ensures the feeding speed.

The utility model provides a pair of crowded type device of broach type heat dissipation section bar, heat dissipation section bar feed when aluminium extrusion processing is even, and the processingquality of space bar is high, and is not easy crooked, warp or fracture.
