Due to the cooling of the mold, the raw material may condense at the discharge end, causing it to connect with the molded part, resulting in a large protrusion on the outside of the molded part, which affects its quality. Furthermore, the top and bottom of the lamp cup are prone to burrs when they separate from the mold, and the burrs need to be polished, which requires an extra amount of work. Therefore, a precision forming mold for lamp hardware is needed to solve the existing shortcomings. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-5As shown, this utility model provides a technical solution: a precision forming mold for lighting hardware, including a bracket 1, a receiving column 2 fixedly connected to the top of the bracket 1 on opposite sides, a set of symmetrical through pipes 3 fixedly connected inside the receiving column 2, a movable column 4 movably connected at the center of the receiving column 2, an inner mold 5 movably connected to the bottom of the receiving column 2 through the movable column 4, a forming part 6 sleeved on the outer side of the inner mold 5, a material guiding mechanism 7 provided inside the inner mold 5, a control mechanism 8 provided at the top of the receiving column 2, and the control mechanism 8 is connected to the material guiding mechanism 7 and the movable column 4 respectively, a set of symmetrical demolding mechanisms 9 provided on opposite sides of the bracket 1, and the forming part 6 is located on the opposite side of the demolding mechanism 9.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the material guiding mechanism 7 includes a rotating rod 701, a first gear 702, a first rack 703, and a second rack 704. The rotating rod 701 passes through the first gear 702, and the rotating rod 701 is fixedly connected to the first gear 702. The first rack 703 is symmetrically arranged about the axis of the rotating rod 701 with the origin as the origin. The first gear 702 is located on the opposite side of the first rack 703, and the first rack 703 meshes with the first gear 702. The first rack 703 is horizontally arranged, and the second rack 704 is longitudinally arranged. The second rack 704 is movably connected to the inside of the inner mold 5, and the second rack 704 meshes with the first gear 702. 02 is movably connected to the inside of the inner mold 5 via a rotating rod 701, and rack 703 is movably connected to the inside of the inner mold 5. An adjusting column 10 is movably connected inside the movable column 4. The bottom end of the adjusting column 10 is rotatably connected to the top end of rack 704. A set of symmetrical moving grooves 11 are opened on the outside of the inner mold 5. The moving grooves 11 are all L-shaped, and the inside of each moving groove 11 is movably connected to a limiting strip 12. The limiting strip 12 is L-shaped. The end of rack 703 away from gear 702 is fixedly connected to the inside of the limiting strip 12. The bottom end of the through pipe 3 is connected to the moving groove 11.

[0024] Rack 2 704 moves downward, driving gear 1 702 to rotate around the rotating rod 701, thereby driving rack 1 703 to move closer to each other, pulling the limiting strip 12 to move along the moving groove 11. At this time, the top of the limiting strip 12 releases the seal on the bottom of the through pipe 3, and the material inside the through pipe 3 can flow into the interior of the chamber along the moving groove 11 until the interior of the chamber is full of material. When the limiting strip 12 is reset, it makes it easy for the chamber to be completely sealed. The outer side of the limiting strip 12 acts as part of the chamber, preventing the material inside the chamber from connecting with the material inside the outlet, thus separating them during the cooling time, facilitating the demolding of the subsequent molded part 6, and preventing the material from condensing at the outlet.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, the control mechanism 8 includes gear 2 801, gear 3 802, fixed frame 803, and servo motor 804. Movable column 4 passes through gear 2 801 and is fixedly connected to gear 2 801. Gear 3 802 is movably connected to the top of receiving column 2 via a rotating shaft, and gear 2 801 meshes with gear 3 802. Fixed frame 803 is fixedly connected to the top of receiving column 2. Servo motor 804 is fixedly connected to the top of fixed frame 803, and the output end of servo motor 804 is fixedly connected to the rotating shaft of gear 3 802. Hydraulic rod 13 is fixedly connected to the top of fixed frame 803. The telescopic end of hydraulic rod 13 is fixedly connected to the top of adjusting column 10. Grinding ring 14 is fixedly connected to the top of inner mold 5, and grinding ring 2 15 is fixedly connected to the bottom of inner mold 5. The top and bottom of molded part 6 are respectively attached to the bottom of grinding ring 14 and the top of grinding ring 2 15.

[0026] The servo motor 804 is started, driving gear 3 802 to rotate. Since gear 2 801 meshes with gear 3 802, gear 2 801 and movable column 4 rotate synchronously. Since the adjusting column 10 is rotatably connected to rack 2 704, the adjusting column 10 remains fixed. At this time, the inner mold 5 rotates relative to the inner side of the molded part 6, and the grinding ring 14 rubs against the top of the molded part 6, and the top of the grinding ring 2 15 rubs against the bottom of the molded part 6. Thus, the inner mold 5 grinds the inner wall of the molded part 6 and detaches from it, and the burrs on the top and bottom of the molded part 6 are ground off. Then, the hydraulic rod 2 903 is used to control the outer mold 902 to move away from the molded part 6, and the molded part 6 detaches under its own weight.

[0027] like Figure 1 As shown, the demolding mechanism 9 includes a base 901, an outer mold 902, and a hydraulic rod 903. The hydraulic rod 903 is fixedly connected to the top of the base 901, and the outer mold 902 is movably connected to the top of the base 901. The telescopic end of the hydraulic rod 903 is fixedly connected to the back side of the outer mold 902. The outer side of the inner mold 5 and the inner side of the outer mold 902 form a cavity.

[0028] Working principle: In use, firstly, the hydraulic rod 903 controls the outer mold 902 to move closer and fit together, forming a cavity between the inner mold 5 and the outer mold 902. Grinding ring 14 seals the top of the cavity, and grinding ring 15 seals the bottom. The through pipe 3, moving groove 11, and cavity are connected or closed by the position of the limiting strip 12. Raw materials can be injected into the cavity through the through pipe 3. Specifically, the hydraulic rod 13 controls the adjusting column 10 to move downwards, thereby moving rack 704 downwards, causing gear 702 to rotate around the rotating rod 701, thus moving rack 703 closer together. This pulls the limiting strip 12 along the moving groove 11. At this time, the top of the limiting strip 12 releases the seal on the bottom of the through pipe 3, allowing the raw material inside the through pipe 3 to flow into the cavity along the moving groove 11 until the cavity is full. When the control limit bar 12 is reset, the through pipe 3 is sealed, making the chamber completely sealed. After the raw material cools into the molded part 6, the servo motor 804 is started, driving gear 3 802 to rotate. Since gear 2 801 meshes with gear 3 802, gear 2 801 and movable column 4 rotate synchronously. Since the adjusting column 10 is rotatably connected to rack 2 704, the adjusting column 10 remains fixed. At this time, the inner mold 5 rotates, and the inner side of the inner mold 5 rotates relative to the inner side of the molded part 6. The grinding ring 14 rubs against the top of the molded part 6, and the top of the grinding ring 2 15 rubs against the bottom of the molded part 6. Thus, the inner mold 5 grinds the inner wall of the molded part 6 and falls off at the same time, and the burrs on the top and bottom of the molded part 6 are ground off. Then, the hydraulic rod 2 903 is used to control the outer mold 902 to move away from the molded part 6, and the molded part 6 falls off under its own gravity.
