Described cooling water guidance tape is a runner plate, and the cooling water channel that communicates in length and breadth is located in the runner plate.
Described cooling water guidance tape is the powder stave, and the cooling water channel that communicates in length and breadth is located in the powder stave.
The described cast gate of going up is located on the upper plate, and described upper runner comprises crossing current road that is located on the runner plate and the straight channel that is located on runner plate, thermal insulation board, heating plate and the upper impression plate, and the crossing current road communicates with straight channel, and straight channel communicates with the submarine gate of counterdie.
Described powder stave is provided with powder tube chamber, and last cast gate is located at bottom, powder tube chamber, and cast gate communicates with straight channel on this, and straight channel communicates with the submarine gate of counterdie; The upper plate bottom is fixed with the powder bucket gland that matches with the chamber activity of powder tube.
Compared with prior art, the utility model has been set up the runner plate or the powder stave of band cooling water channel between the upper plate of patrix and upper impression plate, the heating plate of thermal insulation board and charged thermal element, adopted the cold runner system to replace traditional TOP-TIP, isolate upper impression plate and runner plate or powder stave with thermal insulation board, and at runner plate, add cooling system between powder stave and the glue muzzle, significantly reduced the temperature of each runner and glue muzzle, the sizing material of this part can not cured, under the effect of machine pressure, make these sizing materials enter die cavity, again be utilized, therefore saved the sizing material resource; Adopt this structure also not need the sizing material in the runner is taken out from mould, cancelled the action of getting stub bar, thereby can realize 24 hours continuous production, and improved productivity ratio, reduced cost significantly, but because Mould design and manufacturing become complicated, therefore, the manufacturing process difficulty improves, and die cost rises, this can hardly be avoided, and just investment cost increases.
