Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an environmentally friendly hot extrusion split flow combined mold. Background Art

[0002] A hot extrusion die is a die used in hot extrusion molding process, usually composed of multiple parts, which is used to extrude metal billets into products of specific shapes under high temperature and high pressure.

[0003] Publication No. CN201841172U discloses a hot extrusion die for forming multi-core cavity aluminum alloy profiles, including an upper die and a lower die, wherein the upper die is composed of an upper layer die and a lower layer die, wherein the upper layer die is provided with an inner die core and a plurality of first diverter holes, wherein the bottom end of the lower layer die is provided with an outer die core having an inner die hole, wherein the top end of the lower layer die is provided with a third diverter hole coaxial with the inner die hole, and a plurality of second diverter holes penetrating the upper and lower end surfaces of the lower layer die, wherein an outer die hole flow supply channel is formed from the first diverter hole through the second diverter hole to the outer die hole on the lower die, and an inner die hole flow supply channel is formed from the first diverter hole through the third diverter hole to the inner die hole. The die has a long service life, is easy to process and repair, and has stable profile forming during production. Although this type of hot extrusion die has multiple diversion holes, it is lacking in environmental protection. Since this type of hot extrusion die does not have a structure for disassembling the upper die and the lower die, when the lower die or the upper die is damaged, one die cannot be replaced alone, but the entire die can only be replaced together, which not only increases the cost of use, but also requires the damaged die to be recast, thereby increasing carbon emissions and causing pollution to the environment.

A disc spring 7 is arranged inside the fixed plate B5, one end of the disc spring 7 is connected to the surface of the clamping block 6, and the other end is connected to the inner surface of the fixed plate B5. The design of the disc spring 7 plays an effect of driving the clamping block 6 to slide inside the fixed plate B5. The internal sliding connection of the fixed plate B5 is the clamping block 6, and the material of the clamping block 6 is an iron block. The design of the iron block material of the clamping block 6 plays an effect of facilitating the clamping block 6 to be clamped into the fixing hole 13 by the electromagnet 10. The internal sliding connection of the fixed plate A4 is a slide rod 8, and the surface of the slide rod 8 is sleeved with a spring 9, and one end of the spring 9 is connected to the surface of the fixed plate A4. The other end is connected to the surface of the electromagnet 10. The design of the spring 9 has the effect of driving the electromagnet 10 to be sleeved on the surface of the fixed sleeve 12. The electromagnet 10 is fixedly installed on the surface of the slide rod 8, and the electromagnet 10 is slidably connected to the upper mold 1. The surface of the electromagnet 10 is fixedly installed with a shift block 11, and the surface of the upper mold 1 is fixedly installed with a fixed sleeve 12. The electromagnet 10 and the fixed sleeve 12 are slidably connected. The sliding design of the electromagnet 10 and the fixed sleeve 12 has the effect of facilitating the sliding of the block 6 outward through the electromagnet 10. The fixed sleeve 12 is slidably connected to the fixed plate B5. The sliding design of the fixed sleeve 12 and the fixed plate B5 has the effect of facilitating the assembly of the upper mold 1 and the lower mold 2. A fixing hole 13 is opened through the surface of the fixed sleeve 12, a discharge port 14 is opened through the interior of the lower mold 2, and a welding chamber 15 is opened inside the lower mold 2.

[0025] Embodiment 2

[0026] See also Figure 1-4 The surface of the upper mold 1 is rotatably connected with a rotating block 16, and a screw rod 17 is fixedly installed on the surface of the rotating block 16. The design of the screw rod 17 facilitates the up and down adjustment of the mold core 18. The screw rod 17 is rotatably connected to the upper mold 1. The rotating design of the screw rod 17 facilitates the downward movement of the mold core 18 through the rotation of the screw rod 17, thereby adjusting the size of the welding chamber 15, thereby improving the adaptability of the hot extrusion mold. The surface of the screw rod 17 is connected with the mold core 18 through a thread, and the mold core 18 is slidably connected to the upper mold 1. The mold core 18 fits against the inner wall of the upper mold 1, and the fitting design of the mold core 18 and the inner wall of the upper mold 1 prevents the aluminum material from flowing into the upper mold 1.

[0027] Working principle: When it is necessary to fit the upper mold 1 and the lower mold 2 together, it is only necessary to sleeve the fixing sleeve 12 on the surface of the fixing plate B5. At this time, the electromagnet 10 will be sleeved on the surface of the fixing sleeve 12 under the elastic force of the spring 9, and the electromagnet 10 will drive the clamping block 6 to slide into the fixing hole 13. After the fixing block is inserted into the fixing hole 13, the upper mold 1 and the lower mold 2 can be fixed. When it is necessary to disassemble them, it is only necessary to slide the electromagnet 10 upward through the shifting block 11. After the electromagnet 10 is away from the clamping block 6, the clamping block 6 will be subjected to the elastic force of the disc spring 7 to slide the clamping block 6 out of the fixing hole 13. At this time, the upper mold 1 and the lower mold 2 can be separated. The spring 9, the fixing plate A4, the fixing plate B5, the fixing hole 13, the fixing sleeve 12 and the electromagnet The iron 10 facilitates the disassembly and assembly of the upper die 1 and the lower die 2, thereby facilitating the disassembly and replacement of the upper die 1 and the lower die 2 separately, avoiding the need to recast the entire die, thereby achieving an environmental protection effect. When it is necessary to adjust the size of the welding chamber 15, it is only necessary to rotate the rotating block 16, which will drive the screw 17 to rotate, and the screw 17 will move the core 18 downward through the thread. After the core 18 moves to a certain position, the size of the welding chamber 15 can be adjusted. The design of the core 18 and the screw 17 has the effect of adjusting the size of the welding chamber 15, thereby improving the adaptability of the hot extrusion die while also avoiding the situation where the aluminum billet flows into the upper die 1.
