Description
Technical Field
[0001] The utility model belongs to the technical field of ring drill type cooling integrated material pipes, and in particular relates to a novel ring drill type cooling integrated material pipe. Background Art
[0002] The ring drill type cooling integrated material pipe includes the material pipe body, material pipe mounting ring, mold end material pipe mounting, circulating cooling water channel, aluminum liquid pouring port, cooling water inlet and outlet, etc.
[0003] At the front end of the material tube body connected to the mold side, because the raw material tube adopts a whole ring groove water cooling design, the wall thickness of the material tube connecting to the mold end is relatively thin. When the whole ring groove water cooling method is adopted, the thickness of the bottom of the cooling ring groove is very small from the inner wall of the material tube. When the high-temperature aluminum alloy melt enters the inner wall of the material tube from the "aluminum liquid pouring port" and then flows into the mold cavity at high speed through the front end of the material tube, the thickness of the ring groove cooling bottom and the inner wall of the material tube is too thin, which is very easy to crack. During the high-temperature die-casting process, when the inner wall of the material tube cracks and the cooling water enters the inner cavity of the material tube and contacts the high-temperature aluminum alloy melt, a corresponding explosion accident will occur. Utility Model Content
[0004] The purpose of the present invention is to provide a novel ring drill type cooling integrated material pipe to solve the problems raised in the above background technology.

[0006] Preferably, one end of each cooling channel extends obliquely to the outside of the mold end material pipe mounting portion, and one end of each cooling channel is connected and mounted on a side wall of an adjacent cooling channel.
[0007] Preferably, a plurality of internal threaded interfaces connected to corresponding cooling channels are provided on the outer wall of the mold end material tube mounting portion, and each of the internal threaded interfaces is provided with a plug for sealing, and a sealing gasket is provided between the plug and the internal threaded interface.
[0008] Preferably, each of the plugs is provided with a support rod extending into the cooling channel, and spiral blades are spirally provided on the support rod.
[0009] Preferably, the mold end material pipe mounting portion is provided with a cooling water inlet and a cooling water outlet connected to two circulating cooling water channels in sequence, and a connecting water channel connected to two cooling channels is provided between the two circulating cooling water channels.

[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] (1) The present invention updates the original ring-shaped water cooling method to a "ring-drill cooling" method by adding a plurality of cooling channels that are connected in sequence, thereby not changing the strength, toughness and other conditions of the thin-walled material tube here; ensuring that the material tube is not prone to cracking during the injection process and ensuring its stability during use.
[0013] (2) The present invention connects adjacent cooling channels laterally. Since the ring drill cooling channel is circular, the internal stress will not gather together but will be dispersed when the unit water flow rate remains unchanged.
[0014] (3) The present invention facilitates stirring of the liquid in the cooling channel during its flow by adding support rods and spiral blades in each cooling channel, thereby improving the cooling effect of the liquid and avoiding uneven heating of the liquid.
