[0002] Molds are the various molds and tools used in industrial production to produce desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. Simply put, a mold is a tool used to create a shaped object. This tool is composed of various parts, and different molds are composed of different parts. It primarily achieves the desired shape by changing the physical state of the material being molded. Molds are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression or injection molding of products such as engineering plastics, rubber, and ceramics.

[0003] When using the existing die-casting mold, it is inconvenient to remove the product after the upper and lower molds are closed. The product needs to be manually removed from the molding cavity of the lower mold, which is time-consuming and labor-intensive, and is not conducive to improving production efficiency. Therefore, a die-casting mold with a steering function is needed to solve this problem. Utility Model Content

[0004] The utility model provides a die-casting mold with a steering function. After the mold is closed, the lower mold moves downward and automatically turns over to pour out the product in the lower mold, which is convenient for demoulding and has a good use effect.

[0022] See also Figure 1-5 , a die-casting mold with a steering function, including a bracket 1, four symmetrically distributed support columns 2 are fixedly connected between the upper and lower end surfaces inside the bracket 1, and a slide 3 is slidably connected to the upper side of the outer wall of the four support columns 2, and the lower end surface of the slide 3 is fixedly connected to the upper mold 4, and the upper end surface of the bracket 1 is installed with an electric push rod 5 fixedly connected to the slide 3 at the output end, and the lower sides of the outer walls of the two support columns 2 on the same side are slidably connected to the slide 6, and a rotating plate 7 is provided between the two slide rods 6, and the upper end surface of the rotating plate 7 is fixedly connected to the lower mold 8. The left and right end surfaces inside the bracket 1 are rotatably connected to the first connecting rod 9 through a coupling, and the two ends of the two first connecting rods 9 are rotatably connected to the second connecting rod 10 through a coupling, and the other ends of the two second connecting rods 10 on the upper side are rotatably connected to the slide 3 through a coupling, and the outer walls opposite to each other of the two slide rods 6 are fixedly connected with sleeves 11, and the other ends of the two second connecting rods 10 on the lower side are rotatably connected to the two sleeves 11 respectively;

[0023] The left and right end surfaces of the rotating plate 7 are fixedly connected with a rotating shaft 12, and the other ends of the two rotating shafts 12 pass through two sleeves 11 respectively and are rotatably connected to the slide rod 6 and the sleeve 11. The outer wall of the left rotating shaft 12 is fixedly connected with a gear 13, and the lower side of the left end surface inside the bracket 1 is fixedly connected with a straight rack 14.

[0024] In this embodiment, the electric push rod 5 is started, and the electric push rod 5 drives the slide plate 3 and the upper mold 4 to move downward along the support column 2, and then drives the front end of the first connecting rod 9 to rotate downward through the second connecting rod 10 on the upper side, and then drives the slide bar 6 to slide upward along the support column 2 through the second connecting rod 10 and the sleeve 11 on the lower side. The two slide bars 6 further drive the rotating plate 7 to move upward through the rotating shaft 12, and then drive the lower mold 8 to move upward to close the mold with the upper mold 4. After the die-casting of the product is completed, the electric push rod 5 drives the slide plate 3 and the upper mold 4 to move upward, and then drives the first connecting rod 10 and the sleeve 11 to rotate downward. The connecting rod 9 and the second connecting rod 10 drive the rotating plate 7 and the lower mold 8 to move downward synchronously and separate from the upper mold 4. The die-cast product remains in the lower mold 8. When the rotating plate 7 moves downward, the rotating shaft 12 drives the gear 13 to move downward and engage with the spur rack 14, thereby causing the gear 13 to roll on the outer wall of the spur rack 14. The gear 13 further drives the rotating shaft 12 on the left to rotate, thereby driving the rotating plate 7 to rotate, causing the rotating plate 7 and the lower mold 8 to flip 180°. The product in the lower mold 8 falls downward under the action of gravity, making demoulding convenient and reducing labor.

[0025] As a technical optimization solution of the present invention, the other end of the right rotating shaft 12 is fixedly connected to a third connecting rod 15, the right end face of the third connecting rod 15 is fixedly connected to a short column 16, and the right end face inside the bracket 1 is fixedly connected to a sliding groove 17 that is slidably connected to the short column 16, and the outer wall of the sliding groove 17 is provided with a notch 18.

[0026] In this embodiment: at the moment when the gear 13 moves downward and engages with the spur rack 14, the short column 16 just moves to the notch 18. After the gear 13 and the spur rack 14 are engaged, the gear 13 drives the rotating plate 7 and the rotating shaft 12 on the right to rotate synchronously, and then drives the third connecting rod 15 and the short column 16 to rotate, so that the short column 16 can smoothly rotate from the notch 18 to the outside of the slide groove 17. The gear 13 continues to roll downward and disengages from the spur rack 14. The short column 16 rotates again to the inside of the slide groove 17. The short column 16 slides in the slide groove 17 to limit the rotating shaft 12, preventing the rotating shaft 12 and the rotating plate 7 from rotating at will when the gear 13 is not engaged with the spur rack 14.

[0027] As a technical optimization solution of the present invention, the outer wall of the notch 18 is provided with rounded corners.

[0028] In this embodiment, rounded corners are provided at the notch 18 to facilitate smooth entry of the short column 16 into the chute 17 .

[0029] As a technical optimization solution of the present invention, the diameter of the short column 16 is equal to the width of the inner wall of the sliding groove 17.

[0030] In this embodiment, the diameter of the short column 16 is set to be equal to the width of the inner wall of the sliding groove 17, so that the short column 16 can slide stably in the sliding groove 17.

[0031] As a technical optimization solution of the present invention, the axis of the rotating shaft 12 and the center line of the sliding groove 17 are located in the same vertical plane.

[0032] In this embodiment, by arranging the axis of the rotating shaft 12 and the center line of the sliding groove 17 in the same vertical plane, the rotating plate 7 can remain horizontal when the short column 16 slides in the sliding groove 17.

[0033] As a technical optimization solution of the present invention, a controller 19 is provided on the outer wall of the bracket 1 , and the electric push rod 5 is electrically connected to the controller 19 .

[0034] In this embodiment, the controller 19 can control the electric push rod 5 to work normally.

[0035] The working principle and use process of the utility model are as follows: when in use, the electric push rod 5 is first started, and the electric push rod 5 drives the slide plate 3 and the upper mold 4 to move downward along the support column 2, and then drives the front end of the first connecting rod 9 to rotate downward through the second connecting rod 10 on the upper side, and then drives the slide bar 6 to slide upward along the support column 2 through the second connecting rod 10 and the sleeve 11 on the lower side. The two slide bars 6 further drive the rotating plate 7 to move upward through the rotating shaft 12, and then drive the lower mold 8 to move upward to close the mold with the upper mold 4. After the die-casting of the product is completed, the electric push rod 5 drives the slide plate 3 and the upper mold 4 to move upward. The first connecting rod 9 and the second connecting rod 10 drive the rotating plate 7 and the lower mold 8 to move downward synchronously and separate from the upper mold 4. The die-cast product stays in the lower mold 8. When the rotating plate 7 moves downward, the rotating shaft 12 drives the gear 13 to move downward and engage with the spur rack 14, so that the gear 13 rolls on the outer wall of the spur rack 14. The gear 13 further drives the rotating shaft 12 on the left to rotate, and then drives the rotating plate 7 to rotate, so that the rotating plate 7 and the lower mold 8 are flipped 180 degrees. The product in the lower mold 8 falls downward under the action of gravity, which makes demoulding convenient and reduces labor.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
