Embodiment

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figure 2 , a cooling structure for placing point cold at an extremely short position in a new type of die-casting mold of the present utility model includes a super short point cold pipe body 3, an insert pin 2, and an insert pin sleeve 1. The top end of the super short point cold pipe body 3 is connected to the insert pin 2 through a thread. An insert pin sleeve 1 is sleeved on the insert pin 2. The first cooling extension pipe 4 and the second cooling extension pipe 5 are connected to the super short point cold pipe body 3. The top of the first cooling extension pipe 4 is connected to the first super point cold quick connector 6, and the top of the second cooling extension pipe 5 is connected to the second super point cold quick connector 7. The super point cold quick connector is connected to a water collecting base (or a die-casting machine).

[0020] Figure 3 As shown, the ultra-short spot cooling tube body 3 is provided with a cooling water hole 31 and a central tube 32, which can spray water for cooling, and the central tube 32 is placed inside the insert pin 2.

The ultra-spot cooling tube protection sleeve 8 is provided with a clearance position from the ultra-short spot cooling tube body and covers the insert pin 2. The ultra-spot cooling tube protection sleeve 8 is used to fix the extending direction of the cooling extension tube and press the insert pin and the insert pin sleeve to prevent them from retreating.

[0025] The first ultra-spot cooling quick connector 6 and the first ultra-spot cooling quick connector 7 are provided with through holes for water inlet and outlet, and the mouth part is provided with an internal thread to be connected to the first direct cooling extension tube 4 and the second direct cooling extension tube 5.

[0026] The heat of the insert pin 2 is taken away by the circulating cooling water in the inlet and outlet pipes, thereby reducing the temperature of the die-casting part, improving the quality of the pressed product, and solving the pain point that the product quality is unqualified due to the inability to arrange cooling in a narrow area.

[0027] The cooling structure of the present utility model is composed of an insert pin sleeve 1, an insert pin 2, an ultra-short spot cooling tube body 3, a cooling extension tube, an ultra-spot cooling quick connector, and an ultra-spot cooling tube protection sleeve 8, effectively solving the problem of inability to install cooling. On the basis of solving the rapid cooling of the feeding port, while improving the production efficiency, the situation of faults is effectively reduced.
