Based on the above, the utility model aims to provide an extrusion die for avoiding the tail shrinkage of the surface of an aluminum profile, so as to solve the technical problem that the tail shrinkage phenomenon is possibly caused by impurities and dust on the surface of raw materials or insufficient reserved size of residual materials at two ends in the extrusion process when the aluminum profile is extruded by the existing extrusion device.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the extrusion die for avoiding the shrinkage of the aluminum profile surface comprises a hydraulic cylinder, wherein an extrusion plate is arranged on one side of the hydraulic cylinder, a shell is arranged on one side, away from the hydraulic cylinder, of the extrusion plate, a threaded shaft is arranged between the shell and the extrusion plate, and a sleeve is sleeved on the threaded shaft.
Through adopting above-mentioned technical scheme, the sleeve through the screw thread axle cooperation setting of setting restricts the stripper plate to the material, and both ends residual reserve the size and arouse the tail phenomenon inadequately.
The utility model is further characterized in that a scraper is arranged on one side, close to the hydraulic cylinder, of the shell, the scraper is in a funnel shape, and a diversion block and a discharge hole are arranged in the shell.
Through adopting above-mentioned technical scheme, through the scratch ware that sets up to the aluminum product surface because raw and other materials surface impurity, dust or extrusion in-process take place to shrink the tail phenomenon.
The utility model is further characterized in that an inner sleeve ring is sleeved in the shell, the scraper, the flow dividing block and the discharge hole are all connected with the inner sleeve ring, and connecting blocks are symmetrically arranged on the inner sleeve ring and fixedly connected with the shell.
Through adopting above-mentioned technical scheme, through the connecting block that the interior lantern ring cooperation that sets up, under the condition of lining environment variation, can be through the interior lantern ring with inside whole dismantlement, and then change or maintain, increased the life of device, prevent simultaneously at extrusion in-process because the inside lining problem leads to the emergence of tail phenomenon of shrinking.
The utility model is further characterized in that a damping structure is arranged at the joint of the threaded shaft and the shell, and the threaded shaft is rotatably arranged through the damping structure.
Through adopting above-mentioned technical scheme, through the damping structure that sets up, to when the extrusion board extrusion sleeve, drive the pivot and rotate, limit the rotational speed of screw thread axle through the damping structure that sets up, further limited, extrusion board to aluminum product extruded speed to prevent because extrusion speed is too fast to lead to the aluminum product to take place to shrink the tail phenomenon.
In summary, the utility model has the following advantages:
according to the utility model, the threaded shaft is matched with the sleeve, when the extruding plate extrudes aluminum materials by the hydraulic cylinder, extrusion is limited, so that the device can prevent the tail shrinkage caused by insufficient residual materials, meanwhile, the rotating speed between the sleeve and the threaded shaft is limited by the damping structure, the tail shrinkage caused by the fact that the hydraulic cylinder extrudes at an excessive speed suddenly is prevented, and further, the inner sleeve of the ear is arranged, when the lining environment is poor, the inner structure can be detached by the inner sleeve, and the inner sleeve can be replaced or repaired, so that the tail shrinkage is prevented.

Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the utility model.
Hereinafter, an embodiment of the present utility model will be described in accordance with its entire structure.
The utility model provides an avoid aluminium alloy surface to shrink extrusion die of tail, as shown in fig. 1-4, including pneumatic cylinder 1, pneumatic cylinder 1 one side is provided with stripper plate 2, one side that pneumatic cylinder 1 was kept away from to stripper plate 2 is provided with shell 5, the shell 5 endotheca is equipped with interior lantern ring 10, scraper 8, reposition of redundant personnel piece 6, discharge gate 7 all are connected with interior lantern ring 10, its scraper 8 is because raw and other materials surface impurity, dust or extrusion in-process take place to shrink the tail phenomenon to the aluminium alloy surface, the discharge gate 7 that reposition of redundant personnel piece 6 cooperation set up makes the aluminium alloy by reposition of redundant personnel rethread discharge gate 7 that sets up plastic extrusion again, thereby obtain the aluminium alloy after the shaping.
