Abstract
Description
Technical Field
[0001] The utility model relates to the field of metal profile processing, in particular to a mold nitrogen spring anti-leakage structure. Background Art
[0002] With the development of society, molds are needed when producing aluminum alloy profiles. The extruded aluminum alloy ingot is first preheated to 450℃-550℃, and then the preheated aluminum ingot is pressed into the mold from the extrusion barrel and extruded into shape by the mold. During the production process, the high heat generated by the deformation and friction of the metal will be transmitted to the profile and the mold, reaching the highest point at the die hole outlet. The faster the extrusion speed, the higher the temperature rises. In order to avoid the aluminum profile being too hot and resulting in waste, liquid nitrogen is often used to cool the aluminum profile in the prior art. In the prior art, it was found in long-term use observation that when the existing liquid nitrogen is used to cool the mold, the liquid nitrogen is generally discharged through a pipeline. However, during the discharge process, the nitrogen is likely to leak out through the gaps, thereby accelerating the consumption of nitrogen and causing a waste of resources. Therefore, a mold liquid nitrogen cooling anti-leakage device is proposed to address the above problems. Utility Model Content

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0017] Combine Figure 1 and Figure 2 A mold nitrogen spring anti-leakage structure includes a mold 1, a lower pipe 2 is fixedly connected to the top of the mold 1, a ball valve 3 is fixedly connected to the top of the lower pipe 2, an upper pipe 4 is fixedly connected to the top of the ball valve 3, an infusion pipe 5 is slidably connected to the top of the upper pipe 4, a storage box 6 is fixedly connected to the top of the infusion pipe 5, a groove 7 is provided at the bottom end of the outside of the infusion pipe 5, and placement grooves 8 are provided on the left and right sides of the upper pipe 4. An electric push rod 9 is fixedly connected to the placement groove 8, and a tenon 10 is fixedly connected to the output end of the electric push rod 9. The height of the tenon 10 is consistent with the height of the groove 7.
[0018] The structural design between the groove 7 and the tenon 10 is not only simple and convenient to operate, but also forms a sealed space while aligning with the mold 1 to deliver nitrogen, thereby reducing nitrogen leakage, reducing resource waste, and saving costs;
[0019] Combine Figures 1 to 4 A motor 11 is fixedly connected to the left side of the spherical valve 3, and the output shaft of the motor 11 is fixedly connected to the rotating shaft 12. The rotating shaft 12 passes through and is fixedly connected to the spherical valve 3. A pressure sensor 13 is fixedly connected to the top of the upper pipe 4. The pressure sensor 13 is located below the storage box 6. The electric push rod 9 and the motor 11 are both electrically connected to an external control switch.
[0020] The cooperation between the pressure sensor 13, the electric push rod 9 and the motor 11 makes the whole process mechanized, without the need for manual operation. It is simple and efficient, not only saving labor costs, but also avoiding liquid nitrogen freezing injuries caused by improper human operation.
[0021] Working principle: During use, the user electrically connects the electric push rod 9, motor 11 and pressure sensor 13 with the external control switch. When the storage box 6 is aligned with the upper pipe 4 and installed, the pressure sensor 13 sends a signal to the control switch. The control switch controls the electric push rod 9 to push and connect the tenon 10 with the groove 7, so that the storage box 6 is fixed and stably located on the top of the upper pipe 4. At the same time, the control motor 11 drives the rotating shaft 12 to rotate, opens the ball valve 3, and allows the liquid nitrogen to enter the mold 1 along the lower pipe 2 for cooling. When the liquid nitrogen in the storage box 6 is used up, the pressure sensor 13 senses the weight change and sends a signal. The control switch controls the motor 11 to reverse and close the ball valve 3, closing the channel. At the same time, the electric push rod 9 is retracted, and the storage box 6 can be taken out for replacement, which can reduce nitrogen leakage, reduce resource waste, and save costs.
[0022] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
