[0036] The present application provides a die casting machine, such as Figure 1 As shown, it includes a machine tool 10, a feeding cylinder 20, an injection assembly 30 and an adjustment assembly 40;

[0037] Among them, a starting plate 11 and a fixed plate 12 are arranged side by side and at intervals on the machine tool 10;

[0038] One end of the feed barrel 20 is connected to the fixed die plate 12, and the other end of the feed barrel 20 extends toward the side where the standing plate 11 is located, and the feed barrel 20 is for the punch 33 to slide between;

[0039] The injection assembly 30 includes a cylinder 31, an injection rod 32 and a punch 33. The cylinder 31 is connected to the plate 11, the output end of the cylinder 31 is connected to one end of the injection rod 32, one end of the punch 33 is connected to the other end of the injection rod 32, and the other end of the punch 33 extends toward the feed barrel 20.

[0040] The adjusting component 40 is connected to the standing plate 11 and the fixed plate 12 , and is used to adjust the parallelism between the standing plate 11 and the fixed plate 12 .

[0041] The die-casting machine provided in the present application, in which the parallelism between the standing plate 11 and the fixed plate 12 is adjusted by adjusting the adjustment component 40, that is, the spacing between the standing plate 11 and the fixed plate 12 can be adjusted (reduced or increased). Because the punch 33 is fixedly connected to the injection rod 32, the injection rod 32 is fixedly connected to the injection cylinder 31, and the injection cylinder 31 is fixedly connected to the standing plate 11, the position of the punch 33 can be changed, so that the coaxiality of the punch 33 and the feed barrel 20 meets the standard, thereby improving the service life of the punch 33 and the feed barrel 20.

[0042] It should be noted that in the die-casting machine, parallelism is an important parameter, which determines the accuracy of the mold and the quality of the casting. If the parallelism between the plate 11 and the fixed plate 12 is not good, the cavity of the mold will be inaccurate, thus affecting the quality of the casting. To ensure parallelism, the plate 11 and the fixed plate 12 need to be precisely processed and installed. Usually, a high-precision machine tool 10 is used for processing, and professional measuring tools are used for calibration during installation to ensure that the parallelism between the plate 11 and the fixed plate 12 meets the requirements. In addition, in order to ensure the stability and accuracy of the die-casting process, the material selection of the plate 11 and the fixed plate 12 is also crucial. Generally speaking, the plate 11 and the fixed plate 12 will be made of high-strength, heat-resistant, and wear-resistant materials, such as steel or special alloys, to ensure that they can maintain stable performance and precision during use. However, after a long period of die-casting process, the coaxiality of the punch 33 and the feed barrel 20 changes. Therefore, by adjusting the parallelism between the step plate 11 and the fixed template 12, the position of the punch 33 indirectly connected to the step plate 11 is changed, thereby adjusting the coaxiality of the punch 33 and the feed barrel 20 to meet ≤0.25mm, thereby improving the service life of the punch 33 and the feed barrel 20.

[0043] In application, the standing plate 11 is mainly used to fix the mold to ensure the stability and accuracy of the die-casting process. It is usually connected to the movable plate and the fixed plate 12 by fasteners such as bolts and nuts to form a complete mold structure. The standing plate 11 is also responsible for transmitting pressure to ensure that the pressure distribution during the die-casting process is uniform, so as to obtain high-quality castings. The fixed plate 12 is an important component in the die-casting mold, and it cooperates with the movable plate to form the mold cavity of the mold. The position of the fixed plate 12 is fixed, and it is usually connected to the base or support structure of the die-casting machine to provide stable support. In the die-casting process, the role of the fixed plate 12 is to keep the mold stable, withstand the injection pressure, and prevent the mold from deforming or moving. In addition, the fixed plate 12 is also responsible for providing a channel for demoulding and ejection for the casting to ensure that the casting can be smoothly taken out of the mold. In addition, other parts and connection relationships in the die-casting machine are not the focus of this application, and will not be described in detail here.

[0044] In some embodiments, Figures 1 to 3 As shown, the adjustment assembly 40 includes an adjustment rod 41, and the adjustment rod 41 includes a first end 411 and a second end 412. The first end 411 is provided with a first external thread, and the second end 412 is provided with a second external thread. The directions of the first external thread and the second external thread are opposite. The first end 411 is threadedly connected to the plate 11, and the second end 412 is threadedly connected to the fixed template 12. By rotating the adjustment rod 41, the spacing between the plate 11 and the fixed template 12 can be changed (increased or reduced), so that the relative position of the punch 33 and the feed barrel 20 is changed, and the purpose of adjusting the coaxiality of the two is achieved. Specifically, how to rotate the adjustment rod 41 to increase or decrease the spacing between the plate 11 and the fixed template 12 depends on the relative position of the punch 33 and the feed barrel 20. In other embodiments, the first end 411 can also be threadedly connected to the fixed template 12, and the second end 412 is threadedly connected to the plate 11.

[0045] It should be noted that the length of the adjusting rod 41 is less than the distance between the plate 11 and the fixed plate 12. In other words, there is a gap between the two ends of the adjusting rod 41 and the plate 11 and the fixed plate 12, which is used as an adjustment margin to facilitate the adjustment of the distance between the plate 11 and the fixed plate 12.

[0046] In some embodiments, Figures 1 to 3As shown, the adjustment assembly 40 also includes a first nut 42 and a second nut 43. The first nut 42 is arranged on the side of the plate 11 close to the fixed template 12, and the second nut 43 is arranged on the side of the fixed template 12 close to the plate 11. The first nut 42 is arranged relative to the second nut 43, and the directions of the internal threads of the first nut 42 and the second nut 43 are opposite. The first end 411 is threadedly matched with the first nut 42, and the second end 412 is threadedly matched with the second nut 43. In this way, the first end 411 of the adjustment rod 41 can be threadedly connected and matched with the plate 11, and the second end 412 of the adjustment rod 41 can be threadedly connected and matched with the fixed template 12. When the adjustment rod 41 is rotated, the spacing between the plate 11 and the fixed template 12 can be adjusted, that is, the parallelism between the two can be adjusted, and finally the purpose of adjusting the coaxiality between the punch 33 and the feed barrel 20 is achieved. In a specific embodiment, the first nut 42 is a right-handed nut, and the second nut 43 is a left-handed nut; in other embodiments, the first nut 42 is a left-handed nut, and the second nut 43 is a right-handed nut. In other embodiments, the first end 411 may be threadedly matched with the second nut 43 , and the second end 412 may be threadedly matched with the first nut 42 .

[0047] In some embodiments, Figures 1 to 3 As shown, there are multiple adjusting rods 41, and the multiple adjusting rods 41 are arranged side by side and at intervals. In a specific embodiment, there are two adjusting rods 41, and one end of the two adjusting rods 41 is connected to the end of the plate 11 close to the machine tool 10, and the two adjusting rods 41 are distributed radially. In this way, the adjustment force of the adjusting rod 41 can be increased, which is convenient for quickly adjusting the distance between the end of the plate 11 and the fixed mold plate 12 close to the machine tool 10. In other embodiments, one end of the adjusting rod 41 can also be connected to the end of the air pump away from the machine tool 10, so that the distance between the end of the plate 11 and the fixed mold plate 12 away from the machine tool 10 can be adjusted.

[0048] In other embodiments, the number of the adjustment rods 41 may also be 1, 3, 4, 5, etc.

[0049] In some embodiments, the first end 411 and the second end 412 are provided with internal threads in opposite directions (not shown), the plate 11 is provided with bolts adapted to the internal threads in the first end 411, and the fixed template 12 is provided with bolts adapted to the internal threads in the second end 412. In other embodiments, the plate 11 can also be provided with bolts adapted to the internal threads in the second end 412, and the fixed template 12 can be provided with bolts adapted to the internal threads in the first end 411. In this way, the two ends of the adjustment rod 41 can still be threadedly connected to the plate 11 and the fixed template 12 respectively, and by rotating the adjustment rod 41, the distance between the plate 11 and the fixed template 12 can be changed, and finally the coaxiality between the punch 33 and the feed barrel 20 can be adjusted.

[0050] In some embodiments, the adjustment assembly 40 includes a telescopic rod (not shown in the figure), one end of which is connected to the plate 11, and the other end of which is connected to the fixed plate 12. That is, the distance between the plate 11 and the fixed plate 12 is changed by extending and retracting the telescopic rod, thereby changing the parallelism between the plate 11 and the fixed plate 12.

[0051] In some embodiments, Figures 1 to 3 As shown, the adjustment assembly 40 further includes a fixing rod 44, one end of which is connected to the standing plate 11, and the other end of which is connected to the fixed plate 12. In this way, the standing plate 11 and the fixed plate 12 can be ensured to remain relatively stable.

[0052] In some embodiments, Figures 1 to 3 As shown, the fixed rod 44 and the adjusting rod 41 are arranged side by side and at intervals, and the fixed rod 44 is located above the adjusting rod 41. In a specific embodiment, a plurality of fixed rods 44 are provided, and the plurality of fixed rods 44 are arranged side by side and at intervals. In a specific embodiment, the number of the fixed rods 44 and the adjusting rods 41 are both 2, and two fixed rods 44 are located above the adjusting rod 41, that is, the two adjusting rods 41 are arranged at one end of the standing plate 11 and the fixed die plate 12 close to the machine tool 10, and the fixed rod 44 is arranged at one end of the standing plate 11 and the fixed die plate 12 away from the machine tool 10. In this way, the fixed rod 44 can fix the end of the standing plate 11 and the fixed die plate 12 away from the machine tool 10 to enhance its stability; and the parallelism between the standing plate 11 and the fixed die plate 12 is adjusted by the adjusting rod 41 below, and finally the coaxiality adjustment of the punch 33 and the feed barrel 20 is achieved.

[0053] In some embodiments, Figures 1 to 3 As shown, a spanner 45 is provided on the adjusting rod 41. Specifically, a spanner 45 is provided on the first end 411. In other embodiments, a spanner 45 may be provided on the second end 412, or a spanner 45 may be provided on both the first end 411 and the second end 412. Further, a spanner 45 position is provided on the adjusting rod 41, in which the spanner 45 is embedded, so as to facilitate adjustment. The adjusting rod 41 is twisted by the spanner 45, so as to change the spacing between the die plate 11 and the fixed die plate 12, and finally the coaxiality of the punch 33 and the feed barrel 20 meets the requirements.
