Description

Technical Field

[0001] This utility model relates to the field of extrusion die technology, and in particular to an extrusion die assembly device. Background Technology

[0002] Extrusion technology has wide applications in many material preparation fields, such as aluminum alloys and copper alloys. It is also widely used in the silver alloy field, mainly for the preparation of silver-based electrical contact materials, silver-copper brazing filler metals, and silver-magnesium-nickel alloys. In the extrusion of silver and copper alloys, due to the high extrusion pressure and short die life, the extrusion die is designed with a die sleeve and a die core. When the die is damaged, only the die core needs to be replaced, reducing material usage costs. To save costs, the number of die sleeves is generally reduced, with one die sleeve supporting multiple die cores. However, this increases the operation of replacing the die cores.

[0003] The industry primarily employs manual core replacement. This involves hoisting the entire mold onto a workbench, unloading the core, inverting the mold sleeve, and then placing the core to be replaced into the sleeve. However, this method is not only labor-intensive and inefficient, but also poses significant safety hazards. Especially when the mold is in a hot-assembly state, the high-temperature environment further exacerbates the occupational health risks and on-site safety risks for operators. Therefore, there is an urgent need for an extrusion mold loading and unloading device that can achieve rapid and safe core replacement. Summary of the Invention

[0004] To address the problems of high labor intensity, low efficiency, and safety hazards associated with existing die core replacement methods, this utility model provides an extrusion die assembly device. By installing a loading and unloading platform at the bottom of the overhead crane system, a die assembly platform is fixed on the loading and unloading platform, and a die placement rack, a die core placement rack, and a disassembly and assembly device are fixed on the die assembly platform. This eliminates the need for manual removal of the die core, enabling rapid loading and unloading of the die sleeve and die core of the extrusion die.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An extrusion die assembly device includes a gantry crane system.

The assembly / disassembly device enables mechanized mold assembly, improving safety during assembly and disassembly.

[0009] Furthermore, a mold loading and unloading rack is provided on the side of the mold assembly platform. The mold loading and unloading rack includes a mold support and a mold frame. The mold support is fixed to the upper part of the loading and unloading platform and is fixed to the mold assembly platform. The mold frame is set on the mold support. The mold loading and unloading rack facilitates the lifting and transportation by the overhead crane system and also facilitates the timely replacement of the mold to be disassembled.

[0010] Furthermore, a limit switch is fixed on the mold support. When the loading and unloading platform is installed in the designated position, the limit switch contacts the gantry crane system, and the gantry crane system operates normally.

[0011] Furthermore, a mold sleeve storage rack is fixed on the loading and unloading platform, and the mold sleeve storage rack is located below the mold loading and unloading rack. This facilitates the storage of mold sleeves.

[0012] Furthermore, a mold core storage rack is also fixed on the loading and unloading platform for easy storage of mold cores.

The lifting plate is disposed in the groove, and the cylinder three is fixedly connected to the lifting plate. The mold core placement rack and the disassembly device are both fixed on the lifting plate. This facilitates adjustment of the height between the mold placement rack and the mold core placement rack.

[0014] Furthermore, the mold placement rack is fixed with a locking block for mold positioning.

[0015] The beneficial effects of this utility model through the above technical solution are: This invention features a loading and unloading platform at the bottom of the overhead crane system. A mold assembly platform is fixed on this platform, which in turn houses a mold placement rack, a mold core placement rack, and a disassembly / removal device.

The telescopic end of the cylinder 36 passes through the groove and is fixedly connected to the lifting plate 37. The mold core placement rack 32 and the disassembly device are both fixed on the lifting plate 37. This facilitates the adjustment of the position of the mold core and the mold during loading and unloading.

[0027] A mold loading and unloading rack 2 is provided on the side of the mold assembly platform 3. The mold loading and unloading rack 2 includes a mold support 21 and a mold frame 22. The bottom of the mold support 21 is fixed to the loading and unloading platform 6, and the side of the mold support 21 is fixedly connected to the mold assembly platform 3. The mold frame 22 is set on the mold support 21 and includes four mold placement areas. The height of the mold placement areas is greater than the mold diameter. This facilitates the placement or lifting of assembled molds by the overhead crane system 1.

[0028] To improve the safety of the overhead crane system 1, limit switches 23 are provided on the mold support 21. In this embodiment, there are two limit switches 23, fixed on adjacent sides of the mold support 21. When the loading / unloading platform 6 is placed in the designated position, the limit switches 23 contact the overhead crane system 1, and the overhead crane system 1 starts to operate.

[0029] The loading / unloading platform 6 is also equipped with a mold sleeve storage rack 4 and a mold core storage rack 5 for placing mold sleeves and mold cores. The mold sleeve storage rack 4 includes multiple mold sleeve storage areas; in this embodiment, four mold sleeve storage areas are provided on the mold sleeve storage rack 4. The height of each mold sleeve storage area is greater than the diameter of the mold sleeve. The mold core storage rack 5 includes multiple mold core storage areas; in this embodiment, four mold core storage areas are provided on the mold core storage rack 5. The height of each mold core storage area is greater than the diameter of the mold core.

[0030] In this embodiment, a rocker arm-type control panel is installed on the gantry crane system to control electrically controlled devices such as the track system, cylinder 14, cylinder 34, cylinder 36, travel motor 13, and limit switch 23.

When the electro-permanent magnet lifter 35 contacts the mold core, it is activated to hold the mold core. At this time, the cylinder 34 retracts, driving the push rod 33 and the electro-permanent magnet lifter 35 to move in the opposite direction, so that the electro-permanent magnet lifter 35 pulls the mold core out of the mold. Then, the electro-permanent magnet lifter 35 is closed, and the disassembled mold core and mold sleeve are placed on the mold core storage rack 5 and the mold sleeve storage rack 4. Mold disassembly is completed.

[0033] When it is necessary to adjust the distance between the mold placement rack 31 and the mold core placement rack 32 during loading and unloading, the lifting plate 37 is moved up and down by the cylinder 36. The mold core placement rack 32 fixed on the lifting plate 37 and the disassembly and assembly device move up and down with the lifting plate 37 to adjust the height between the mold core placement rack 32 and the mold placement rack 31.
