Description

Cooling pipeline of integrated die casting die Technical Field The utility model relates to the field of mold cooling, in particular to a cooling pipeline of an integrated die-casting mold. Background In order to ensure the temperature balance of the mold cavity, a corresponding cooling pipeline is usually required to be arranged on the mold, and cooling of the mold cavity is realized by circulating a cooling medium in the cooling pipeline. In the prior art, for example, in the utility model patent "mold" with the publication number CN208359407U, a plurality of adjusting channels extending transversely and longitudinally along the insert are provided on the fixed mold insert, and a plurality of first distributing channels and second distributing channels are provided longitudinally above the adjusting channels, wherein the first distributing channels are connected with the adjusting channels through first connecting channels, and the second distributing channels are connected with the first distributing channels through second connecting channels. The cooling pipeline is complex to set and troublesome to process. And the temperature of the regulating channel is only 10-15 mm away from the surface of the cavity, the heat exchange distance between the regulating channel and the cavity is small, the temperature of the product cavity when the product cavity is filled with aluminum liquid is 680-700 ℃, the temperature of the cooling pipeline is 20-200 ℃, the temperature difference between the regulating channel and the cooling pipeline is large, and the cooling pipeline can perform very severe heat exchange, so that the cooling pipeline is easy to cause cracking and breakage of a die under the effects of thermal stress and thermal fatigue, the service life of the die is reduced, the whole insert is required to be replaced after the die core is cracked, and the maintenance cost is high. Disclosure of Invention The utility model discloses the nature provides an integration die casting die's cooling pipeline to the problem that above-mentioned exists, and it is through setting up the water proof piece in the blind hole, makes the cooling medium in the blind hole can flow, makes the blind hole end more be close to the die cavity simultaneously, carries out the heat exchange through cooling medium flow blind hole end and die cavity, takes place that violent heat exchange's area is littleer, and the mould takes place fracture, collapses the risk that lacks lower. The cooling pipeline of the integrated die casting die comprises a die, wherein a cooling pipeline is arranged on a die core of the die, the cooling pipeline comprises a plurality of blind holes which are arranged on the die core and extend downwards from the upper end face of the die core, and a plurality of connecting channels which extend horizontally, each connecting channel is communicated with at least three blind holes, the distance between the bottom of each blind hole and the surface of a die cavity of the die core is 30-40 mm, the connecting channels are higher than the bottom of each blind hole, the distance between the bottom of each blind hole and the bottom of each blind hole is 30-80 mm, each blind hole comprises an inlet channel, a middle channel and an outlet channel, a water-proof sheet is arranged in each middle channel, and a passageway for cooling medium circulation is reserved between each water-proof sheet and the bottom of each blind hole and between each water-proof sheet and the walls of two sides. Preferably, the orifices of the middle channels are all provided with plugs, and the water-proof sheets are fixed on the plugs. Preferably, the inlet channel and the outlet channel are located on either side of the intermediate channel. Preferably, the distance between the water-proof sheet and the hole bottom is 8-12 mm, and the distance between the water-proof sheet and the hole walls at two sides is 0.05-0.2 mm.
