[0002] Automotive parts are the various units that make up a car and the products that serve the car. There are many types of automotive parts, including metal components and metal products such as car chassis panels. As people's living standards improve, their car consumption is increasing, and the market for automotive parts is growing larger. These metal products are generally produced using molds.

[0003] When the upper and lower molds of some molds are joined together, air will remain in the cavity between the upper and lower molds. The air in the cavity is not easy to be discharged after the mold is closed. As a result, when the melt is injected into the cavity, the molded product formed after the melt cools and solidifies is prone to sand holes and cold material. Utility Model Content

[0030] like Figures 1 to 7 As shown, this is an embodiment of the present invention, relating to a mold for producing metal products, including a mold body 10. The mold body 10 includes an upper mold plate 20, a lower mold plate 30, a lower mold core 40, a first ejection assembly 50, and a second ejection assembly 60. The upper mold plate 20 and the lower mold plate 30 are interlocked. The upper mold plate 20 has a first venting plate 21 at both ends, and a plurality of protrusions 22 are provided on one side of the first venting plate 21. The lower mold plate 30 has a second venting plate 31 at both ends, and a plurality of grooves 32 are provided on one side of the second venting plate 31. The grooves 32 are matched with the protrusions 22. The first ejection assembly 50 and the second ejection assembly 60 are respectively connected to the lower mold core 40.

[0031] Furthermore, a feed pipe 23 is provided on one side of the upper mold plate 20, and the feed pipe 23 is connected to the lower mold core 40. Specifically, the melt enters the mold body 10 through the feed pipe 23 for molding.

[0032] Furthermore, guide posts 24 are connected to the four corners of the upper template 20, and the guide posts 24 are movably connected to the lower template 30. Specifically, the guide posts 24 enable the upper template 20 and the lower template 30 to be effectively connected, improving the convenience of processing.

[0033] Furthermore, a slanted guide post 25 is connected to one side of the upper template 20, and the slanted guide post 25 is connected to the second demolding assembly 60. Specifically, the slanted guide post 25 is provided and connected to the second demolding assembly 60. When the upper template 20 is raised, the slanted guide post 25 moves away from the second demolding assembly 60. At this time, the second slider insert 61 of the second demolding assembly 60 slides backward, the product separates from the second slider insert 61, and the product 11 is demolded.

[0034] Furthermore, the lower template 30 has movable column holes 33 at its four corners, which are movably connected to the guide columns 24. Specifically, the movable column holes 33 are matched and moved with the guide columns 24 to effectively connect the upper template 20 and the lower template 30, improving the convenience of processing.

[0035] Furthermore, the lower mold core 40 is provided with a first flow channel 41 on its front side, and a second flow channel 42 communicating with the first flow channel 41 is provided on both sides of the lower mold core 40; the first flow channel 41 is connected to the feed pipe 23; the second flow channel 42 is connected to the second venting plate 31. Specifically, the melt flows into the first flow channel 41 through the feed pipe 23, and then enters the mold body 10 for molding, while the remaining melt flows into the groove 32 of the second venting plate 31 through the second flow channel 42 to achieve venting and slag removal.

[0036] Furthermore, the first ejection assembly 50 includes a first slider insert 51, a first slider seat 52, and a drive module 53. The first slider insert 51 is connected to the lower mold core 40; the first slider seat 52 is connected to one side of the first slider insert 51; and the drive module 53 is used to drive the first slider seat 52 to move. Specifically, the drive module 53 drives the first slider seat 52 to move, thereby causing the first slider insert 51 to move, and thus ejecting the product 11 from the mold.

[0037] Furthermore, the drive module 53 is a drive cylinder, which is connected to the lower template 30 via a mounting bracket 54. Specifically, during demolding, the drive cylinder is used as the drive module 53 to drive the first slider insert 51 away from the product 11, and in conjunction with the second slider insert 61 of the second demolding assembly 60, effectively demolding the product 11.

[0038] Further, the second ejection assembly 60 includes a second slider insert 61, a second slider seat 62, a reset rod 63, and a reset spring 64; the second slider insert 61 is connected to one side of the second slider seat 62; the second slider seat 62 is connected to one end of the reset rod 63, and the upper surface of the second slider seat 62 has an oblique insertion hole 65, and guide blocks 66 are provided on both sides of the second slider seat 62; the reset rod 63 is connected to a limit block 67, and the reset rod 63 passes through the limit block and is connected to the second slider seat 62; the reset spring 64 is wound around the end of the reset rod 63 away from the limit block 67. Specifically, when the upper template 20 is raised, the oblique guide post 25 leaves the oblique insertion hole 65, at which time the second slider insert 61 of the second ejection assembly 60 slides backward, the product 11 separates from the second slider insert 61, the product 11 is ejected from the mold, after the product 11 is removed, under the action of the reset spring 64, the second slider seat 62 is driven to reset, thereby driving the second slider insert 61 to reset.

[0039] This invention features first venting plates 21 on both sides of the upper mold 20 and second venting plates 31 on both sides of the lower mold 30, resulting in a reasonable overall design. During operation, if the melt contains air bubbles, causing a small amount of air between the upper mold 20 and the lower mold 30, the air can be forced into the first and second venting plates 21 and 31 when the melt is injected into the upper and lower molds 20 and 30. Finally, after the product 11 solidifies, the excess structure between the first and second venting plates 21 is removed from the product 11, ensuring that the accuracy of the main structure of the product 11 is not affected, thus further improving the accuracy of the product 11. This application facilitates the expulsion of air from the mold, ensuring venting of the high-column structure of the product 11, reducing sand holes and cold material generation, and improving the accuracy of the product 11.

[0040] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent.
