Description

Technical Field

[0001] The utility model relates to the technical field of extrusion dies, in particular to a flow guide device for an aluminum profile extrusion die and an extrusion die. Background Art

[0002] Extrusion is a common method for forming aluminum profiles. The specific steps are to use an extrusion piston rod to extrude the heated aluminum rod into the mold. After the material is discharged from the mold, it is cooled and cut to obtain the aluminum profile of the required size. The extrusion mold is an essential basic tooling in the extrusion process. For the extrusion forming of aluminum profiles with complex shapes, two or more components (such as forming molds and guide molds) are often required to be assembled and used. The assembly or disassembly of the forming mold and the guide mold of the existing extrusion mold is usually connected by bolts, which is not conducive to rapid assembly and disassembly. Once a gap appears on the end face of the connection between the forming mold and the guide mold after assembly, the aluminum rod will enter the gap after deformation during the extrusion process, which is not conducive to the smooth extrusion of the aluminum rod deformed in the guide mold from the forming groove of the forming mold, affecting the quality of the aluminum profile. To this end, we have introduced a guide device and an extrusion mold for aluminum profile extrusion molds. Utility Model Content

[0014] Compared with the prior art, the utility model has the following beneficial effects: the utility model can realize the connection and fixation of the forming mold, the flow guide mold and the flow guide cylinder by locking the bolts. When disassembling, the bolts are loosened so that the bolts no longer abut against the movable ring seat.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-8 The utility model provides a technical solution: a flow guide device for an aluminum profile extrusion die, comprising a mounting seat 1 for mounting a forming die 16 and a flow guide die 8; a forming through groove 163 is provided in the middle of the forming die 16, and a flow guide groove 9 is provided in the middle of the flow guide die 8.

[0027] The upper end of the mounting seat 1 is provided with an arc-shaped groove 2 for placing the forming die 16 and the guide die 8, and the four corners of the upper end of the arc-shaped groove 2 are provided with a limit plate 3. With this arrangement, after the forming die 16 and the guide die 8 are placed in the arc-shaped groove 2, the limit plate 3 can prevent the forming die 16 and the guide die 8 from falling from the arc-shaped groove 2;

[0028] An extension platform 10 is provided at the rear end of the bottom of the mounting seat 1, and a support member 17 is connected to the rear end of the bottom of the forming die 16, and the bottom of the rear end of the support member 17 is inserted into the positioning groove 11 on the extension platform 10. When the extrusion piston rod extrudes the heated aluminum rod 7 into the guide tube 4 and the guide groove 9 and discharges the material through the forming groove 163, due to the hindrance of the deformation of the aluminum rod 7, the extrusion piston rod forms an extrusion force from front to back on the forming die 16 and the guide die 8 as a whole, which is not conducive to the forming die 16 and the guide die 8 being firmly fixed on the mounting seat 1. At this time, through the setting of the support member 17, the bottom of the rear end of the support member 17 is inserted into the positioning groove 11 on the extension platform 10, so that the support member 17 can have a supporting force from back to front on the forming die 16 and the guide die 8 as a whole, and play a supporting role on the forming die 16 and the guide die 8 as a whole.

[0029] like Figure 5 As shown, a movable ring seat 12 is provided in the annular groove 18 at the rear end of the guide die 8, an annular baffle 13 is fixed to the outer side of the rear end of the annular groove 18, and the front end of the annular baffle 13 is connected to the rear end of the movable ring seat 12 through a spring 15;

[0030] Such a configuration enables the movable ring seat 12 to move to the front of the annular groove 18 under the elastic force of the spring 15 in the initial state, so that the movable ring seat 12 drives the tensioning connector to retract into the annular groove 18;

[0031] The front end of the guide mold 8 is fixed with a guide tube 4 by bolts 5, and a flange ring 6 formed integrally with the guide tube 4 is provided on the outer side of the rear end thereof. The bolts 5 penetrate the flange ring 6 and are screwed to the guide mold 8. Under continuous tightening, the rear end of the bolts 5 enters the annular groove 18 and abuts against the front end surface of the movable ring seat 12.

[0032] The rear end of the movable ring seat 12 is also fixed with a tension connector, the front end of the molding die 16 is provided with plug holes 161 distributed up and down, the plug holes 161 are provided with plug connectors 162 that can be moved forward and backward and locked, and the upper and lower inner walls of the plug holes 161 are provided with card slots 165;

[0033] After the bolt 5 is tightened, the movable ring seat 12 is pushed to move backward, so that the tensioning connector is inserted into the plug hole 161. At this time, the plug connector 162 is inserted into the middle of the tensioning connector, so that the upper and lower sides of the tensioning connector are opened and stuck in the slot 165, thereby realizing the locking and fixation of the forming mold 16, the guide mold 8 and the guide tube 4.

[0034] The annular baffle 13 is fixed to the outer side of the rear end of the annular groove 18 by means of screws 14 , and the inner diameter of the annular baffle 13 is smaller than the outer diameter of the movable ring seat 12 .

[0035] The tensioning connector includes a connecting column 121 fixed to the rear end of the movable ring seat 12 and two upper and lower tensioning heads 122 connected to the rear end of the connecting column 121. The movable ring seat 12, the connecting column 121 and the upper and lower tensioning heads 122 are integrally formed, and a plug-in groove 123 is provided between the upper and lower tensioning heads 122. The upper and lower dimensions of the plug-in groove 123 gradually increase from front to back.

[0036] The diameter of the plug connector 162 gradually decreases from the back to the front, so that after the plug connector 162 is inserted into the plug slot 123 , the upper and lower tensioning heads 122 are opened and snapped into the snap slot 165 .

[0037] The rear end of the molding die 16 is threadedly connected with a T-shaped screw 164 , and the front end of the T-shaped screw 164 extends into the plug hole 161 and is fixedly connected to the middle of the plug connector 162 .

[0038] In addition, in order to achieve the above-mentioned purpose, the utility model also provides an extrusion die, including the flow guide device for the aluminum profile extrusion die.

[0039] Specifically, when in use, the forming die 16 and the guide die 8 are placed in the arc groove 2, so that the limiting plate 3 abuts against the front and rear ends of the forming die 16 and the guide die 8 as a whole;

[0040] Then, the guide tube 4 is fixed to the front end of the guide die 8 by means of the bolt 5, so that the bolt 5 penetrates the flange ring 6 and is screwed to the guide die 8, and under continuous tightening, the rear end of the bolt 5 enters the annular groove 18 and abuts against the front end surface of the movable ring seat 12;

[0041] As the bolt 5 is gradually tightened, the rear end of the bolt 5 pushes the movable ring seat 12 to move toward the rear of the annular groove 18, so that the upper and lower tensioning heads 122 of the tensioning connector extend into the plug hole 161 (such as Figure 6 shown);

[0042] Then, the front end of the plug connector 162 is inserted into the plug slot 123 between the upper and lower tensioning heads 122. Since the upper and lower dimensions of the plug slot 123 gradually increase from front to back, and the diameter of the plug connector 162 gradually decreases from back to front, after the plug connector 162 is inserted into the plug slot 123, the upper and lower tensioning heads 122 are opened and snapped into the snap slot 165 (such as Figure 7 As shown), until the bolt 5 is completely tightened, the forming mold 16, the guide mold 8 and the guide tube 4 are locked and fixed.

[0043] In this way, the end faces of the connection between the forming die 16 and the flow guide die 8 can be closely fitted, so that when the deformed aluminum rod 7 inside the flow guide groove 9 enters the forming through groove 163 under extrusion, it will not enter the gap between the forming die 16 and the flow guide die 8;

[0044] When the forming mold 16, the guide mold 8 and the guide tube 4 need to be disassembled, the T-shaped screw 164 is loosened so that the T-shaped screw 164 drives the plug connector 162 to move toward the front of the plug hole 161 until the plug connector 162 is disengaged from the plug slot 123 between the upper and lower tensioning heads 122. At this time, the upper and lower tensioning heads 122 are no longer squeezed by the plug connector 162, and the upper and lower tensioning heads 122 rebound and reset until the upper and lower tensioning heads 122 are disengaged from the slot 165.

[0045] Then, the bolt 5 is loosened so that the bolt 5 no longer abuts against the movable ring seat 12. At this time, under the elastic force of the spring 15 on the movable ring seat 12, the movable ring seat 12 is reset to the front end of the annular groove 18, so that the movable ring seat 12 drives the tensioning connector to disengage from the plug hole 161 and reset to the annular groove 18;

[0046] Then remove the bolt 5, and disassemble the forming die 16, the flow guide die 8 and the flow guide tube 4 respectively.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
