Multiple sets of fins 14 are equally spaced at the bottom of the heat-conducting plate 13. The heat-conducting plate 13, fins 14 and fins 15 are all aluminum components. The rear end of the air guide shroud 16 is fixed to the front end of the lower mold 1. The air guide shroud 16 is connected to the interior of the inner cavity 12. The rear end of the air guide shroud 16 is fixed to the front end of the lower mold 1. The air guide shroud 16 is connected to the interior of the inner cavity 12.

[0027] Specifically, such as Figures 1-3As shown, the blower 19 and blower 20 can be controlled to start the internal airflow of the guide hood 16. The cold air can be directed to different positions on the left and right through the air outlet 18. The heat conduction plate 13 is arranged on the outside of the cavity 7, which can assist in the absorption and discharge of internal heat and conduct it to the fins 14 and fins 15 on the outside of the heat conduction plate 13. The cold air delivered by the blower 19 and blower 20 can quickly dissipate the heat on the multiple fins 14 and fins 15, and quickly cool the inside of the mold, which can assist in the rapid molding and demolding of the tube fitting. The filter screen 2 can filter and prevent dust inside the mold during air cooling.

[0028] A side plate 3 is provided at the top left side of the lower mold 1, and a side plate 10 is provided at the top right side of the lower mold 1. A horizontal plate 9 is fixed between the rear ends of the side plate 3 and the side plate 10. Two sets of mounting bolts 21 are provided at the bottom left ends of the side plate 3 and the bottom right ends of the side plate 10. Mounting holes 22 are provided inside the top two sides of the lower mold 1.

[0033] Working Principle: In use, this invention utilizes a die-casting mold for die-casting pipe fittings. After the upper mold 6 and lower mold 1 are closed, molten metal is introduced into the mold during the forming process. The heat-conducting plate 13, located outside the cavity 7, assists in absorbing and discharging internal heat, transferring it to the fins 14 and 15 on the outer side of the heat-conducting plate 13. By controlling blowers 19 and 20, air can be blown into the air guide shroud 16. Cool air can be directed to different positions on the left and right using the air outlet 18. The use of blowers 19 and 20 further enhances the cooling effect. The cold air supplied by 20 can quickly dissipate heat from multiple sets of fins 14 and 15, rapidly cooling the inside of the mold and assisting in the rapid molding and demolding of the tube fitting. At the same time, when using the die-casting mold, the side plate 3, the horizontal plate 9, and the side plate 10 can be used to help seal the outer side of the top of the lower mold 1 to prevent foreign objects from entering during mold closing. Furthermore, during mold use, the level bubble level 24 on the lower mold 1 and the upper mold 6 can be used to quickly check the levelness of the lower mold 1 and the upper mold 6 after the die-casting mold is closed, ensuring the accuracy of the tube fitting die-casting process.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
