Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

The utility model provides a muscle material compensation extrusion die, shown in fig. 3, including guide plate 1 and mould main part 2, guide plate 1 and mould main part 2 are connected and are formed extrusion die, run through on the guide plate 1 and be equipped with water conservancy diversion hole 3, mould main part 2 is close to guide plate 1 one side indent and is equipped with interior cavity 13, interior cavity 13 and water conservancy diversion hole 3 shape match, and interior cavity 13 links to each other with water conservancy diversion hole 3 when guide plate 1 and mould main part 2 compound die and is commonly used for the shaping chamber of constituting the section bar outer wall, this shaping chamber mainly used shaping is the semicircle outer wall of section bar as shown in fig. 1, and use prior art guide plate 1 as shown in fig. 2 to the shaping semicircle outer wall can be perfect shaping, and when shaping the supporting rib 14 as shown in fig. 1, because of the barrier of crossbeam 15, lead to the aluminum product feed of supporting rib 14 department less, and then make the supporting rib 14 shaping thinner, or thickness inhomogeneous, lead to production quality to be poor.

As an improvement, in the device, a core material forming frame 4 is arranged in the middle of the flow guide hole 3, one end of the core material forming frame 4, which is far away from the die main body 2, is provided with a back hole 5, and when in extrusion forming, aluminum materials enter the back hole 5 to increase the feeding amount of the core material part; because more aluminum materials can enter the core material forming frame 4 from the back holes 5 during hot pressing, the feeding amount of the supporting ribs 14 during extrusion forming can be ensured, the product quality of profile extrusion forming can be effectively improved, the supporting ribs 14 can be fully formed, and the production quality is effectively improved due to uniform thickness.

Specifically, the diversion holes 3 penetrate through the diversion plate 1 along the axial direction of the diversion plate 1, and three diversion holes 3 are arranged in a central symmetry manner, as shown in fig. 3 and 4, a fixing beam 6 for fixing the core material forming frame 4 is formed between two adjacent diversion holes 3, three fixing beams 6 are arranged, and the three fixing beams 6 are designed in a central symmetry manner with the core material forming frame 4 as the center; one end of the fixed beam is fixedly connected with the core material forming frame 4, and the other end of the fixed beam is fixedly connected to the inner wall of the guide plate 1; the diversion holes 3 can ensure sufficient feeding of the outer walls of the profiles, and compared with the currently used cross beams 15, the three fixing beams 6 are additionally provided with one fixing beam 6, so that the core material forming frame 4 can be stably fixed, and the strength of the die is improved.

The core material forming frame 4 comprises a base 7 and a forming work head 8, and the forming work head 8 is fixedly arranged on one side of the base 7, which is close to the die main body 2. The aluminum material entering the back hole 5 needs to directly enter the forming head 8, so that the back hole 5 is required to be communicated with the inside of the forming head 8, specifically, as shown in fig. 3, 4 and 5, the forming head 8 comprises a plurality of forming heads 9 which are uniformly arranged at intervals, the forming heads 9 are arranged at intervals in a fence shape, a gap between two adjacent forming heads 9 is a feeding gap 10, the feeding gap 10 is a channel through which the aluminum material passes when being extruded, the aluminum material flowing out of the feeding gap 10 after extrusion is finished forms a supporting rib 14, the back hole 5 is used for increasing the aluminum material supply in the feeding gap 10, specifically, the back hole 5 is penetrated and communicated between the feeding gaps 10 upwards from the bottom of the base 7, the upper end of the back hole 5 is communicated with the forming core material hole 11, and the back hole 5 passes through the core material hole 11 to enter each feeding gap 10 when the aluminum material is hot pressed, so that the feeding amount of the rib for supporting the inside the profile can be improved, the rib supporting the rib can be effectively improved, and the disadvantage that the rib is not uniform in the hot pressing of the two cores is avoided because the rib is provided with the uneven supporting material.
