[0002] The new energy control box is an electric power control device used in new energy devices and is the core component of new energy power control. Before the components of the control box are assembled, the control box shell needs to be die-casted using a die-casting mold.

[0003] After searching, the patent number CN215786679U discloses a deep cavity thin-walled shell die-casting mold. After the drive motor of the die-casting mold is started, the second gear will drive the first gear to rotate. After the first gear rotates, it will drive the drive shaft to rotate. After the drive shaft rotates, it will drive the flip frame to rotate and unfold. After the flip frame rotates and unfolds, the die-casting lower mold will be inverted. After the die-casting lower mold is inverted, the workpiece in the die-casting lower mold can be quickly poured out.

[0004] If the cooling effect of the mold is not good during the die-casting process, it is easy to cause a certain degree of adhesion between the molded shell and the inner wall of the mold. At this time, even if the lower mold is turned over, the shell cannot be removed, and there is a certain degree of difficulty in demolding. Utility Model Content

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a die-casting mold for a shell of a new energy control box.

[0026] The utility model provides Figure 1-3 A die-casting mold for a new energy control box housing shown includes a frame 1, an upper die 2 is fixedly arranged at the upper end of the inner wall of the frame 1, sliding holes are opened at the lower ends of both sides of the frame 1, sliders 3 are slidably penetrated in the two sliding holes, cross bars 4 are rotatably sleeved inside the two sliders 3, a lower die 5 is fixedly arranged between the two cross bars 4, the upper die 2 and the lower die 5 are matched, electric cylinders 6 are fixedly arranged at both sides of the outer wall of the frame 1, the two electric cylinders 6 are arranged in parallel, the ends of the electric cylinders 6 are fixedly connected to the sliders 3, a rack 7 is fixedly arranged at the lower end of the outer wall of the frame 1, a gear 8 is meshed with the rack 7, and the gear 8 is fixedly sleeved with the cross bar 4;

[0027] A vertical plate 9 is fixedly provided at the bottom of the lower mold 5, and a support block 10 is fixedly provided on the outer wall of the vertical plate 9. The cross-section of the support block 10 is rectangular, and a knocking block 11 is sleeved on the outer side of the support block 10. The knocking block 11 has a sliding hole inside for cooperating with the support block 10 to slide, and a spring 12 is fixed between the inner wall of the sliding hole and the support block 10.

[0028] Before the new energy control box shell is formed, the upper mold 1 and the lower mold 5 are connected, and the shell can be die-casted at this time. After the die-casting, the electric cylinder 6 starts and pushes the slider 3, so that the slider 3 pushes the lower mold 5 through the cross bar 4, so that the lower mold 5 is away from the upper mold 2. After the lower mold 5 is separated from the inside of the upper mold 2, the gear 8 begins to engage with the rack 7. Since the position of the rack 7 is fixed, the gear 8 begins to drive the cross bar 4 to rotate, so that the cross bar 4 drives the lower mold 5 to flip. In this process, the knocking block 11 can move intermittently with the cooperation of the support block 10 and the sliding hole, and the elastic force of the spring 12 is restored to make the knocking block 11 intermittently knock on the outer wall of the lower mold 5, so that the internal casing of the lower mold 5 can stably fall and complete the fall off after being flipped by the knocking, thereby improving the demoulding effect.

[0029] In order to be able to drive the knocking block 11 to perform intermittent knocking work during the flipping process of the lower mold 5, as shown in FIG. Figure 2-3 As shown, a guide ring 14 is fixedly provided on the side of the slider 3 away from the gear 8, and the inner wall of the guide ring 14 is provided with a plurality of guide protrusions symmetrically arranged in a circle, a vertical rod 15 is fixedly provided on the rod wall of the cross bar 4, and a guide rod 17 is fixedly provided on the bottom of the vertical rod 15 through a telescopic rod 16, and the guide rod 17 is in contact with the inner wall of the guide ring 14, and a transmission pulling mechanism is provided between the end of the guide rod 17 away from the guide ring 14 and the knocking block 11, and the transmission pulling mechanism includes a support plate 18, the support plate 18 is fixedly connected to the bottom of the lower mold 5, and a support rod 19 is rotatably penetrated inside, and a guide wheel 20 is fixedly sleeved on the rod wall of the support rod 19, and a pull rope 13 is provided for the internal transmission of the guide wheel 20, and the two ends of the pull rope 13 are respectively fixedly connected to the knocking block 11 and the guide rod 17.

[0030] When the lower mold 5 is flipped, the cross bar 4 rotates. At this time, the cross bar 4 drives the guide rod 17 to rotate through the vertical rod 15 and the telescopic rod 16. Since the guide rod 17 contacts and cooperates with the inner wall of the guide ring 14, the guide rod 17 intermittently contacts with multiple protrusions inside the guide ring 14, and the guide rod 17 moves to the side close to the lower mold 5. At this time, the guide rod 17 pulls the knocking block 11 through the pull rope 13, so that the knocking block 11 pulls the spring 12 with the support of the support block 10, and when the guide rod 17 is separated from the protrusion on the inner wall of the guide ring 14, under the elastic force recovery of the spring 12, the knocking block 11 quickly moves back and knocks on the lower mold 5, so that the shell can fall off from the inside of the lower mold 5.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
