Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a conveying mechanism and its die-casting machine. Background Technology

[0002] Mold manufacturing technology is a key technological area in the manufacturing industry, encompassing multiple stages such as mold design, manufacturing, assembly, and debugging. Molds are indispensable tools in industrial production, widely used in the manufacturing of plastic products, metal products, and electronic components. Mold manufacturing technology boasts advantages such as high efficiency, high consistency, and low material consumption, significantly improving the efficiency and accuracy of the manufacturing process. With the rapid development of the manufacturing industry, the demand for mold manufacturing technology is constantly growing. Modern mold manufacturing technology is evolving towards informatization, intelligence, and integration, continuously generating new technological achievements such as CAD / CAM technology and laser rapid prototyping technology. These technologies are injecting new vitality into the development of the mold manufacturing industry.

[0003] Conveyors are widely used in machinery manufacturing, metallurgy, chemical industry and other fields to transport workpieces, items and materials. They have the motion and power characteristics of general transmission chains and can work stably in low-speed heavy-load environments. Die casting machines inject molten metal into the mold cavity and solidify it through high pressure and high speed to manufacture metal products of various complex shapes. Die casting machines are widely used in automobile manufacturing, electronics and electrical appliances, communication equipment and other industries. They are key equipment for achieving high-precision and high-quality metal product production. In mold manufacturing technology, conveyors are mainly used for transporting the mold after die casting is completed.

[0004] Traditional die-casting machines often suffer from problems such as long cooling times and low efficiency due to the thickness of the product structure and the depth of the ribs, resulting in long product cooling times. The structure can also lead to high mold temperatures and localized overheating, where traditional cooling water cannot effectively cool the mold, requiring extensive spray cooling and causing aluminum adhesion to various parts of the product, resulting in unstable production and low efficiency. Furthermore, the conveyor mechanisms used with die-casting machines are mostly simple conveyor belts, which may not allow for real-time inspection of the produced products, increasing the complexity of subsequent inspection processes and reducing work efficiency. Therefore, this paper proposes a new conveyor mechanism and a corresponding die-casting machine. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in localizing mold cooling in die-casting machines and the difficulty in real-time product monitoring in conveying mechanisms, which leads to reduced production efficiency.

[0027] Example 1

[0028] like Figure 1 - Figure 6 As shown, the present invention proposes a conveying mechanism and a die-casting machine, including a bottom support plate 1. A mold support main plate 6 and a mold support sub-plate 7 are respectively installed on the top of the bottom support plate 1. A main mold plate 23 is installed on the side of the mold support main plate 6 near the mold support sub-plate 7. A sub-mold plate 24 is installed on the side of the mold support sub-plate 7 near the mold support main plate 6. An ejector pin 27 is installed on the inner side of the sub-mold plate 24. A mold core 25 is installed on the inner side of the main mold plate 23. A contouring water channel 29 is provided between the mold core 25 and the main mold plate 23, the sub-mold plate 24, and the ejector pin 27. The two contouring water channels 29 extend to the outer sides of the main mold plate 23 and the sub-mold plate 24 and are equipped with coolant inlets 26. The contouring water channels 29 introduce coolant to assist in mold demolding.

[0029] The top of the bottom support plate 1 is symmetrically and fixedly connected with limit slide rails 9. The two limit slide rails 9 are slidably connected to the main mold support plate 6. The mold support sub-plate 7 is fixedly connected to the bottom support plate 1.

Hydraulic support plate 2 is used to support the first hydraulic mechanism 28, and hydraulic support frame 4 is used to support the second hydraulic mechanism 5.

[0030] A first hydraulic mechanism 28 is fixedly connected to the side of the hydraulic support plate 2 near the mold support main plate 6. The first hydraulic mechanism 28 is fixedly connected to the mold support main plate 6. Multiple limiting slide columns 8 are fixedly connected to the side of the hydraulic support plate 2 near the first hydraulic mechanism 28. The multiple limiting slide columns 8 are slidably connected to the mold support main plate 6. A protective plate 3 is fixedly connected to the outer side of the hydraulic support plate 2. The mold support main plate 6 is used to support the main mold plate 23. The limiting slide columns 8 are used to guide the movement of the mold support main plate 6.

Subsequently, the second motor 18 is controlled to drive the active bevel gear 19 to rotate, which in turn drives the driven bevel gear 20 to rotate. The rotation of the driven bevel gear 20 drives the conveyor cabinet body 21 to move in a circular motion, which in turn moves the product on the conveyor cabinet body 21.

The detection equipment body 16 scans and detects the product to check whether the surface of the produced product meets the standard and whether there are any defects inside the product. This reduces the complexity of subsequent quality inspection and other processes and improves production efficiency.

[0035] Example 2

[0036] like Figure 1 - Figure 6 As shown, based on Embodiment 1, a conveying mechanism includes a conveying rail body 21. Multiple support legs 10 are fixedly connected to the bottom of the conveying rail body 21. A motor box 11 is fixedly connected to the outer side of the conveying rail body 21. A second motor 18 is fixedly connected to the inner side of the motor box 11. A driving bevel gear 19 is fixedly connected to the output end of the second motor 18. A driven bevel gear 20 is fixedly connected to the side of the conveying rail body 21 closest to the second motor 18. The driving bevel gear 19 and the driven bevel gear 20 mesh with each other. The second motor 18 drives the driving bevel gear 19 to rotate, which in turn drives the driven bevel gear 20 to rotate. The driven bevel gear 20 drives the conveying rail body 21 circumferentially, causing the mold on the conveying rail body 21 to move.

[0037] A detection support frame 13 is fixedly connected to the outer side of the conveyor rail body 21.

The detection equipment body 16 is slidably connected to the feed port 12. The reciprocating screw 17 is rotatably connected to the detection support frame 13.

[0038] In this embodiment, during use, the first hydraulic mechanism 28 first pushes the mold support main plate 6 and the two mold support auxiliary plates 7 closer together. Two limiting slide rails 9 limit the movement of the mold support main plate 6. The movement of the mold support main plate 6 drives the movement of the main mold plate 23, which in turn drives the movement of the mold core 25 until the ejector pin 27 and the mold core 25 are in contact. Then, the air between the ejector pin 27 and the mold core 25 is evacuated to a vacuum state. Subsequently, molten aluminum is injected into the inlet 12, simultaneously driving the first hydraulic mechanism 28... The second hydraulic mechanism 5 drives the push rod 22 to squeeze the aluminum liquid in the feed port 12, so that the aluminum liquid in the feed port 12 fills the gap between the mold core 25 and the ejector pin 27. Since the mold core 25 and the main mold plate 23 and the secondary mold plate 24 and the ejector pin 27 are all provided with contouring water channels 29, the design of the contouring water channels 29 is determined by the shape of the mold, thereby cooling the parts of the mold core or ejector pin that cannot be cooled, improving the cooling efficiency of the mold core 25 and the ejector pin 27, shortening the product cooling time, and thus improving production efficiency and product quality.
