Sprue spreader spiral sufficient cooling structure for die-casting die

Abstract

The invention relates to a sprue spreader spiral sufficient cooling structure for a die-casting die. The structure comprises a sprue spreader, a water inlet pipe and a water outlet pipe, wherein the water inlet pipe and the water outlet pipe are transversely arranged inside the sprue spreader; a cooling water well is formed at the middle portion of the sprue spreader vertically; a base is installed in the cooling water well; a groove is formed in the middle portion of the base and communicated with the water outlet pipe; a spiral tower is arranged at the upper end of the base; a spiral and upward water tank is formed in the side wall of the spiral tower; a gap is arranged between the upper end of the spiral tower and the cooling water well; the lower end of the water tank is connected with the water inlet pipe; the upper end of the water tank is communicated with the gap; a through hole is vertically formed in the spiral tower and the base; the upper end of the through hole is communicated with the gap; and the lower end of the through hole is communicated with the groove. According to the sprue spreader spiral sufficient cooling structure, the spiral cooling structure is adopted; the superficial area for cooling is increased; and due to the spiral cooling structure, the whole cooling process is full and uniform, and the efficiency of die-casting production is effectively improved.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a helical and sufficient cooling structure of a die-casting mold with a flow splitter. Background technique [0002] Diverter cone cooling plays a very important role in die-casting production efficiency. At present, the diverter cone cooling water pipe used in die-casting molds is small, and the cooling in the middle of the flow channel is not in place. The flow channel is very thick and large, resulting in serious thermal junction and mold opening. In order to solve the above problems, it is easy to burst and burst, resulting in low production efficiency. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a helical full cooling structure of the split cone of the die-casting mold. The spiral cooling structure is adopted to increase the cooling surface area. Because of the spiral ascending cooling, the entire cooling proces...

[0002] Splitter cone cooling plays a very important role in die casting production efficiency. At present, the splitter cone cooling water pipes used in die-casting molds are small, and the cooling in the middle of the straight-through channel is not in place. The thick straight-through channel leads to serious heat junctions and mold opening When it is easy to burst, resulting in low production efficiency, in order to solve the above problems, a die-casting mold split cone spiral full cooling structure is designed
