[0031] like Figures 1 to 3 As shown, according to a first aspect of the utility model, there is provided an insert-type flange ejector, which includes an ejector block 1 and an elastic component 2.
[0032] In the following description, reference will be made to Figures 1 to 3 The specific structure of the above components of the extended flange ejector and the connection relationship of the above components are specifically described.
[0033] like Figures 1 to 3 As shown, in the embodiment, the ejector block 1 may be formed with a protrusion 10. A groove 30 may be formed on the punch 3. During the operation of the insertion-type flange ejector, the protrusion 10 of the ejector block 1 can be inserted into the groove 30. The elastic component 2 is connected to the ejector block 1 and is used to drive the ejector block 1 to move in a first direction (which may be Figure 1 The protrusion 10 of the ejection block 1 moves in the groove 30 (in the vertical upward direction), thereby driving the protrusion 10 of the ejection block 1 to move in the groove 30. The part 7 can partially cover the groove 30. When the protrusion 10 moves to the position of the part 7 in the groove 30, the protrusion 10 can eject the part 7 from the punch 3. In this process, since the gap between the protrusion 10 and the groove 30 is located inside the groove 30, and the part 7 itself covers the outside of the groove 30, the part 7 will not be stuck in the gap between the protrusion 10 and the groove 30, thereby avoiding the failure of the ejection of the part 7 and causing production downtime.
[0034] Without limitation to this, the elastic component 2 drives the ejection block 1 to move in the vertically upward direction is only a preferred case in the embodiment. As long as the function of ejecting the part 7 can be achieved, the first direction may also be other directions. Figure 2 The flanging ejection mechanism for the mold shown in the figure is placed flat as a whole (i.e. rotated 90° clockwise). In this case, the first direction can be a horizontal direction (i.e. the elastic component can drive the ejection block to move in a horizontal direction), and the ejection block can still eject the part from the punch.
[0035] Preferably, Figures 1 to 3 As shown, in the embodiment, the ejector block 1 can be approximately formed into a rectangular parallelepiped structure. The protrusion 10 can be formed on the side of the ejector block 1 facing the punch 3, so that the protrusion 10 can be easily extended into the groove 30. Specifically, the protrusion 10 can protrude from the side of the ejector block 1 facing the punch 3 toward the direction of the groove 30.
[0036] Preferably, Figures 1 to 3 As shown, in an embodiment, the protrusion 10 may include a plurality of strip-shaped protrusions 101. Specifically, the cross-section of the protrusion 101 may be rectangular, and the length direction of the protrusion 101 may be vertical. One side end of the protrusion 101 is connected to the ejection block 1 (may be integrally formed), and the other side end of the protrusion 101 may extend into the groove 30. A plurality of strip-shaped protrusions 101 may be arranged at intervals in the width direction of the groove 30. When the part 7 is ejected, multiple positions of the part 7 can be uniformly stressed to avoid deformation of the part 7 during the ejection process. More preferably, the number of grooves 30 may be equal to the number of protrusions 101, so that a plurality of protrusions 101 can be arranged one-to-one with a plurality of grooves 30, that is, a protrusion 101 is arranged in each groove 30.
[0037] However, it is not limited to this. The one-to-one correspondence between the plurality of protrusions 101 and the plurality of grooves 30 is only a preferred embodiment of the present invention. In actual use, the plurality of protrusions may be simultaneously located in one groove. In addition, the ejection block may be formed with only one protrusion with a relatively wide width, or the end of the ejection block facing the punch may be extended into the groove as a whole as a protrusion. In this case, the punch may be formed with only one relatively wide groove.
[0038] Preferably, in the embodiment, a gap may be provided between the protrusion 101 and the inner wall of the groove 30 to avoid direct contact between the protrusion 101 and the inner wall of the groove 30, thereby preventing the protrusion 101 from scratching the groove 30. Specifically, a gap may be provided between each side of the protrusion 101 and the inner wall of the corresponding groove 30. More preferably, the width of the gap may be 1 mm to 2 mm. Such a setting can ensure that the protrusion 101 will not scratch the inner wall of the groove 30 during the operation of the extended flange ejector, and the gap will not be too large.
[0039] Preferably, Figure 1As shown, in the embodiment, the insertion-type flange ejector further includes a guide sleeve 4. The guide sleeve 4 may be a circular sleeve. The upper end of the guide sleeve 4 may be bolted to the bottom surface of the ejection block 1, and the lower end of the guide sleeve 4 may be movably connected to the elastic component 2 (i.e., the guide sleeve 4 may be telescopically arranged in the elastic component 2). The elastic component 2 is used to drive the guide sleeve 4 to move along the first direction.
[0040] More preferably, Figure 1 As shown, in an embodiment, the elastic component 2 may include a cylindrical shell and a spring portion (not shown). The interior of the cylindrical shell may be formed with a cylindrical cavity, and the spring portion may be installed in the cylindrical shell. The top of the cylindrical shell may be formed with a circular opening, and the guide sleeve 4 may extend into the cylindrical shell through the opening. The cylindrical shell is sleeved on the outside of the guide sleeve 4. The bottom end of the guide sleeve 4 abuts against the top end of the spring portion in the cylindrical shell, so that the elastic component 2 can provide the guide sleeve 4 with an upward movement force, thereby driving the ejection block 1 to move along the groove 30. Preferably, the guide sleeve 4 is telescopically arranged in the cylindrical shell (that is, the guide sleeve 4 can extend or retract into the cylindrical shell), and a lubricant may be provided between the guide sleeve 4 and the cylindrical shell for lubrication.
[0041] In addition, preferably, Figure 1 As shown, in an embodiment, the extended-in flanging ejector may further include a fixing flange 5. The fixing flange 5 may be arranged at the bottom of the elastic component 2. Specifically, the fixing flange 5 may be bolted to the cylindrical housing. The fixing flange 5 may be formed into a plate-like structure, and the cross-sectional area of the fixing flange 5 in the horizontal direction may be larger than the cross-sectional area of the elastic component 2. The fixing flange 5 may function as a base, so that the extended-in flanging ejector may be stably arranged on the side of the punch 3.
[0042] In addition, if Figure 1 and Figure 2 As shown, according to the second aspect of the utility model, a flanging ejection mechanism for a mold is provided, wherein the flanging ejection mechanism for the mold comprises a compression component 6, a punch 3 and the above-mentioned insert-type flanging ejector. The compression component 6 is used to drive the ejection block 1 in the opposite direction of the first direction (that is, it can be Figure 1 The punch 3 is formed with a groove 30 as described above, and the protrusion 10 of the ejection block 1 extends into the groove 30 to eject the part 7 from the punch 3.
[0043] Preferably, Figure 1 and Figure 2As shown, in an embodiment, the groove 30 can be formed on the first side of the punch 3. The first side can be the side of the punch 3 facing the extended flange ejector. The punch 3 can also be formed with a strip convex edge 31 on the first side. The strip convex edge 31 can be a rectangular parallelepiped convex edge. The length direction of the strip convex edge 31 can be horizontal. The top surface of the strip convex edge 31 can be used to place the part 7. Specifically, the part 7 can be a strip-shaped plate. The part 7 can be bent and covered on the top surface of the strip convex edge 31 and the side of the strip convex edge 31 facing the ejection block 1. The extension direction of the groove 30 can be perpendicular to the length direction of the strip convex edge 31 (that is, the extension direction of the groove 30 can be vertical). Preferably, the groove 30 can pass through the bottom surface of the strip convex edge 31. The groove 30 can extend from the bottom of the strip convex edge 31 to the inside of the strip convex edge 31. The distance between the top of the groove 30 and the top surface of the strip convex edge 31 can be 3mm-4mm. This allows the flange portion of the part 7 (i.e., the portion perpendicular to the top surface of the strip convex edge 31) to cover the end of the groove 30. This arrangement allows the protrusion 10 to easily push the part 7 out of the punch 3 during the movement along the groove 30. Not limited to this, in another embodiment, the groove can pass through the bottom surface and the top surface of the strip convex edge.
[0044] In addition, preferably, the compression component 6 may include an upper die knife block 61 and a lower pressure ejector block 62. Among them, the top of the upper die knife block 61 may be connected to the mold. Specifically, the mold may be a stamping mold. The top of the upper die knife block 61 may be bolted to the upper die seat of the stamping mold, so that the upper die knife block 61 can move in the vertical direction following the upper die seat (i.e., the compression component 6 can move in the vertical direction). The bottom of the upper die knife block 61 may be bolted to the top of the lower pressure ejector block 62. The lower pressure ejector block 62 may be formed as a columnar structure. The bottom surface of the lower pressure ejector block 62 may be formed as a circle. In addition, the bottom surface of the lower pressure ejector block 62 may be parallel to the top surface of the ejection block 1, so that the lower pressure ejector block 62 may press against the top surface of the ejection block 1 during the movement, thereby driving the ejection block 1 to move vertically downward. The compression component 6 cooperates with the elastic component 2 to realize driving the ejection block 1 to reciprocate in the vertical direction.
[0045] During use, when the part 7 is flanging, the upper die seat of the mold is pressed down, driving the upper die knife block 61 downward. The downward pressing ejector block 62 fixed at the lower part of the upper die knife block 61 abuts against the ejector block 1, thereby driving the ejector block 1 to move vertically downward, while pressing down the guide sleeve 4 and compressing the elastic component 2. After the part 7 is completed flanging, the upper die seat of the mold rises, the elastic component 2 rebounds and drives the guide sleeve 4 to rise, thereby driving the ejector block 1 to move vertically upward. During the movement of the ejector block 1, after the protrusion 101 moves along the groove 30 to the position of the part 7, the protrusion 101 can lift the part 7 in the vertical direction, thereby ejecting the part 7 after flanging from the punch 3. And because the gap between the protrusion 10 and the groove 30 is located inside the groove 30, and the part 7 covers the outside of the groove 30, the part 7 will not be stuck in the gap between the protrusion 10 and the groove 30, thereby avoiding the production shutdown caused by the failure of the ejection of the part 7.
[0046] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the above-described embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above-described embodiments within the technical scope disclosed in the present application, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
