生産速度が低下するという欠点があつた。Prior Art and its Problems FIG. 3 is a longitudinal cross-sectional view showing a conventionally used die 2 equipped with a cooling jacket 1 in use. The molten metal 4 in the crucible 3 flows from the hot water supply port 5 to the die 2.
Molten metal is poured into the through hole 6 of. The die 2 is made of graphite, and the through hole provided in the center has a cross section of the desired shape of the finished product 7. The molten metal is cooled and solidified while passing through the through hole, and is drawn out as a finished product. In order to perform this solidification continuously and rapidly, the die 2 is surrounded by a cooling jacket 1 having cooling channels 8. In order to rapidly cool and solidify the molten metal, a large amount of thermal energy must be absorbed in a short period of time, but the conventional structure described above does not have a sufficient cooling effect, so the through hole 6 of the die 2 must be made longer. As a result, the number of ice cream-like semi-solidified areas increases and becomes unstable, so the withdrawal speed of the product 7 had to be slowed down. As a result, the die becomes large,
The disadvantage was that the production speed decreased.

る。Means for Solving the Problems and Effects of the Present Invention The present invention aims to solve the above-mentioned drawbacks. A small-diameter injection pipe having a closing plug as a base is coaxially inserted into the blind pipe waterway, and the closing plug is provided with a water supply hole and a drainage notch, and the cooling water is supplied to each of the blind pipe waterways sequentially or simultaneously. This cooling jacket is characterized in that it is connected to a means for discharging.

Blind pipe waterways 9, 10, 11, 12 are bored parallel to the through hole 6 of the die 2, and a closing plug 13 is screwed into the opening of each blind pipe waterway. The closing plug 13 has a drainage notch 14 in a part of the side wall, and has a water supply hole 15 bent at a right angle in the middle with an inlet in the side wall of the closing plug and an outlet in the end face of the closing plug. Injection pipe 1
Insert 6. At this time, the injection pipe is coaxial with the blind pipe waterway so that its tip 17 reaches near the blind end of the blind pipe waterway.

化した成品７を引出すことができる。 Cooling water is first injected from the supply port 18, passes through the water supply hole 15, the injection pipe 16, and is injected from the tip 17, and then flows through the gap 19 between the blind pipe waterway and the injection pipe toward the closing plug. It is desirable that the injection pipe 16 be a metal tube with a small diameter and as thin a wall as possible. The cooling water that has passed through the blind pipe waterway 9 passes through a communication path 20 that opens facing the drainage notch 14, and then passes through the next blind pipe waterway 10 of the same structure, and then 11, 1.
2 and are discharged from the discharge port 21 in sequence. During this time, the cooling water absorbs heat more efficiently than the blind pipe waterway wall, and further transfers the heat to the new cooling water passing through the injection pipe, rapidly cooling the molten metal passing through the through hole, and drawing out the solidified product 7. can.

排出口２１に向かつて行なう。 In this implementation, cooling water is supplied to each blind pipe channel 9, 10,
11 and 12 are passed through sequentially, but they may be passed through at the same time. That is, cooling water is simultaneously supplied from the supply port 18 to the water supply holes of each blind pipe waterway 9, 10, 11, and 12, and discharged from the drainage notch of each cooling waterway toward the discharge port 21 at the same time.
