Description

Technical Field

[0001] The utility model relates to the technical field of extrusion technology, in particular to an integrated extrusion die for new energy vehicles. Background Art

[0002] An extrusion die is a tool used to extrude a material (usually metal or plastic) through a hole or cavity of a specific shape into a desired cross-sectional shape. This process is widely used to manufacture a variety of profiles, pipes, wires and other products. The design and manufacture of the extrusion die has a vital impact on the quality and performance of the final product.

[0003] For workpieces with a special structure that is larger in the middle and relatively smaller at both ends, there are indeed some challenges when using traditional extrusion dies to produce them. Specifically, after the workpiece is formed, the middle part of the workpiece has a large contact area with the inner wall of the mold, resulting in a large friction force during the demolding process. In order to overcome this friction, it is usually necessary to apply a large demolding force, which not only increases the difficulty of the demolding process, but may also cause damage or deformation of the workpiece, thereby affecting the final quality of the product.

DETAILED DESCRIPTION

[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0032] like Figures 1 to 8 As shown, an integrated extrusion die for new energy vehicles of the utility model comprises: an upper die assembly 1; a lower die assembly 2, which abuts against the upper die assembly 1 and forms a product cavity; a material storage assembly 3, which has a material storage sleeve 4 arranged on the lower die assembly 2, and the material storage sleeve 4 is connected to the product cavity; an ejection assembly 5, which has at least two ejector blocks 6 and at least two movable blocks 7 movably arranged on the upper die assembly 1, the ejector blocks 6 are arranged relatively to each other and are each provided with a first undercut structure 8, the movable blocks 7 are arranged relatively to each other and are each provided with a second undercut structure 9, the ejector blocks 6 and the movable blocks 7 have a first working position and a second working position on the upper die assembly 1, the first undercut structure 8 and the second undercut structure 9 can be movably abutted against each other because the ejector blocks 6 and the movable blocks 7 are both in the first working position, for forming a workpiece; the workpiece can be fixed on the upper die assembly 1 because the ejector blocks 6 and the movable blocks 7 are both in the first working position, and can be separated from the first undercut structure 8 and the second undercut structure 9 because the ejector blocks 6 and the movable blocks 7 are both converted from the first working position to the second working position.

[0033] The upper die assembly 1 is connected to the movable part of the extruder, and the lower die assembly 2 is connected to the fixed part of the extruder. Before the extrusion work starts, the upper die assembly 1 and the lower die assembly 2 need to be separated first, so that the storage sleeve 4 is in an open state, and the operator or the automatic feeding system feeds the required extrusion material into the storage sleeve 4. Subsequently, the upper die assembly 1 is driven by the movable part of the extruder to abut against the upper die assembly 1 to form a product cavity. At this time, the top block 6 and the movable block 7 are in the first working position on the upper die assembly 1, and the first undercut structure 8 and the second undercut structure 9 are abutted to form the workpiece. Subsequently, the extruded material in the storage sleeve 4 flows into the product cavity under the drive of the storage assembly 3. After the workpiece in the product cavity is formed, the upper die assembly 1 is pressed against the upper die assembly 1 to form a product cavity. The mold assembly 1 is separated from the lower mold assembly 2 driven by the movable part of the extruder. At this time, the first undercut structure 8 and the second undercut structure 9 are both pressed against the inner wall of the workpiece, and the workpiece is fixed on the upper mold assembly 1 and separated from the lower mold assembly 2 together with the upper mold assembly 1. Subsequently, the ejector assembly 5 drives the ejector block 6 and the movable block 7 from the first working position to the second working position respectively. At this time, the first undercut structure 8 and the second undercut structure 9 are both smoothly separated from the workpiece, and the demolding of the workpiece from the upper mold assembly 1 is completed. In this process, the ejector assembly 5 can not only efficiently push the molded workpiece out of the mold, but also ensure that no damage is caused to the workpiece during the entire demolding process, thereby ensuring the quality and consistency of the product.

[0034] Furthermore, a guide block 10 is provided on the upper mold assembly 1, and an inclined groove 11 is provided on the guide block 10. An inclined portion 12 is provided on one side of the top block 6, and the inclined portion 12 movably rests on the inclined groove 11. This design not only provides a precise movement path for the top block 6, but also realizes the displacement of the top block 6 in a specific direction through the inclination angle of the inclined groove 11 and the inclined portion 12; when the workpiece in the product cavity is formed, at least two top blocks 6 on the upper mold assembly 1 are in the first working position. At this time, the first undercut structures 8 on each top block 6 are relatively arranged and tightly fit with the inner wall of the workpiece, thereby The workpiece is fixed on the upper die assembly 1, and the upper die assembly 1 drives the workpiece to separate from the lower die assembly 2. After the upper die assembly 1 drives the workpiece to separate from the lower die assembly 2, the ejector assembly 5 starts to work, driving the ejector block 6 to descend in the vertical direction. At the same time, the inclined portion 12 on the ejector block 6 moves along the inclined groove 11 on the guide block 10, so that the ejector block 6 will produce a horizontal displacement while descending. As the ejector block 6 continues to descend, the first undercut structures 8 located on the ejector block 6 gradually approach each other due to the horizontal displacement, which causes the contact area between them and the inner wall of the workpiece to gradually decrease until they are completely separated.

[0035] Furthermore, a connecting block 13 is provided on the upper mold assembly 1, and a sliding groove 14 is provided on the connecting block 13. A sliding portion 15 is provided at one end of the movable block 7 in the vertical direction, and the sliding portion 15 is slidably connected to the sliding groove 14. The setting of the connecting block 13 also limits the movement of the movable block 7 in the vertical direction. When the workpiece in the product cavity is formed, at least two movable blocks 7 on the upper mold assembly 1 are in the first working position. At this time, the second undercut structures 9 on the movable blocks 7 are relatively arranged and are tightly fitted with the inner wall of the workpiece, respectively, and are in contact with the first The undercut structure 8 fixes the workpiece on the upper die assembly 1, and the upper die assembly 1 drives the workpiece to separate from the lower die assembly 2. When the upper die assembly 1 drives the workpiece to separate from the lower die assembly 2, the ejector assembly 5 starts to work, driving the relatively arranged movable blocks 7 to approach each other in the horizontal direction through the sliding portion 15 along the sliding groove 14 on the connecting block 13, so that the second undercut structure 9 is separated from the workpiece, and the fixation of the workpiece is released. The ejector assembly 5 drives the ejector block 6 and the movable block 7 to move synchronously, thereby realizing the release of the workpiece from the upper die assembly 1.

[0036] Specifically, the ejection assembly 5 also includes: a push rod 16, one end of which is hinged to the ejector block 6 through a pin shaft. This design allows the ejector block 6 to flexibly rotate or swing around the pin shaft when subjected to thrust; a push seat 17, one end of the push rod 16 away from the ejector block 6 is connected to the push seat 17, and the push seat 17 is connected to the driving device on the extruder. The power provided by the extruder is transmitted to the push rod 16 through the push seat 17, thereby affecting the position change of the ejector block 6. When the extruder drives the push seat 17 to move upward or downward, the push seat 17 drives the push rod 16 to rise and fall synchronously in the vertical direction, so that the ejector block 6 can rise or fall in the vertical direction. When the ejector block 6 is lifted and lowered due to the action of the push rod 16, due to the design characteristics of the inclined groove 11 on the guide block 10, this not only guides the ejector block 6 to move accurately along the predetermined path, but also prompts the first inverted structure 8 to produce a corresponding displacement in the horizontal direction, thereby driving the relatively arranged first inverted structures 8 to approach or move away from each other in the horizontal direction.

[0037] Specifically, the ejection assembly 5 also includes: a lifting block 18, and the movable block 7 is connected to the lifting block 18, and the lifting block 18 is used to drive the movable block 7 to move; a driving rod 19, the lifting block 18 is connected to one end of the driving rod 19, and a hollow portion is provided on the pushing seat 17, and the other end of the driving rod 19 passes through the hollow portion and is connected to the driving device on the extruder.

[0038] Furthermore, a connecting portion 20 is obliquely arranged on the lifting block 18, and a corresponding connecting groove 21 is arranged on the movable block 7. The connecting portion 20 movably rests against the connecting groove 21. When the connecting portion 20 moves in the vertical direction along the connecting groove 21, it drives the movable block 7 to move in the horizontal direction along the sliding groove 14 on the connecting block 13.

[0039] The driving rod 19 is driven by the driving device on the extruder to drive the lifting block 18 to rise or fall in the vertical direction. At this time, since the movable block 7 is restricted by the connecting block 13 in its vertical movement, the movable block 7 will not rise or fall due to the lifting of the lifting block 18. During this period, the connecting portion 20 on the lifting block 18 slides along the connecting groove 21 on the movable block 7. Since the connecting portion 20 is designed to be in an inclined state, the movable block 7 is forced to slide in the horizontal direction along the sliding groove 14 on the connecting block 13 through the sliding portion 15 thereon, thereby driving the relatively arranged second undercut structures 9 to move closer to or away from each other in the horizontal direction.

[0040] In order to ensure that the extruded material in the storage sleeve 4 can be smoothly pushed into the product cavity, a push block 22 is movably arranged inside the storage sleeve 4. The outer edge of the push block 22 is tightly fitted with the inner wall of the storage sleeve 4 to prevent the extruded material from leaking or overflowing. The push block 22 is connected to the drive device on the extruder through a mechanical connection method such as a connecting rod or a push rod so that its movement can be controlled by the drive device; before the extrusion process starts, the upper mold assembly 1 and the lower mold assembly 2 need to be separated first, so that the storage sleeve 4 is in an open state. At this time, The push block 22 is in a preset position in the material storage sleeve 4, which is convenient for adding extrusion materials. The operator or the automatic feeding system will feed the required extrusion materials into the material storage sleeve 4. Subsequently, the upper mold assembly 1 and the lower mold assembly 2 are closed. Then, the driving device on the extruder is started, and the push block 22 in the material storage sleeve 4 is driven to move along the inner wall of the material storage sleeve 4 through a connecting rod or other transmission mechanism. Since the push block 22 fits tightly against the inner wall of the material storage sleeve 4, it can effectively push the extrusion materials in the material storage sleeve 4 into the product cavity evenly and continuously.
