The side wall of the block is vertically provided with a block mounting convex rail, and a block is slidably mounted on the block mounting convex rail. The lower surface of the block is provided with a protrusion that engages with the limiting slot.

[0007] As a further improvement of the present invention, the support block is provided with a support plate mounting groove that is inclined toward the side away from the column and extends in a direction perpendicular to the extension direction of the slide rail. The support plate mounting groove is provided with a support plate mounting plate that extends in the same direction and whose upper edge is connected to the lower plate surface of the support plate. A hinge shaft is horizontally provided through the plate surface of the support plate away from the column, with its two ends respectively hinged to the side walls of the support plate mounting groove. A positioning pin is horizontally provided through the plate surface of the support plate near the column. Both side walls of the support plate mounting groove are provided with at least two support plate positioning holes for the positioning pin to be inserted.

[0008] As a further improvement of the present invention, one end of the positioning pin extends through the positioning hole of the support plate to the outside of the support block, and the outer wall of the positioning pin located outside the support block is provided with an anti-detachment groove, and the outer wall of the support block is provided with an anti-detachment plate, one end of which overlaps in the anti-detachment groove and the other end of which is hinged to the support block by a plate mounting screw.

[0009] As a further improvement of the present invention, a top-tightening protrusion mounting groove is vertically provided on the side wall of the column, which runs through the entire column, and a T-shaped block is provided on the side wall of the top-tightening protrusion facing the column, which is slidably installed in the top-tightening protrusion mounting groove.

[0010] As a further improvement of the present invention, the lower surface of the clamping protrusion abuts against the upper end surface of the clamping protrusion limiting step provided on the outer wall of the column.

[0011] As a further improvement of the present invention, a locking block is provided above the pressure plate, and a screw rod is vertically provided on the lower surface of the locking block, which penetrates the pressure plate downward and is threadedly connected to the upper end face of the column; the pressure plate is provided with a screw rod through-hole for the screw rod to pass through, and the screw rod through-hole is a strip-shaped through-hole extending in the same direction as the pressure plate.

The clamping protrusion placement assembly includes two parallel channel steels with the slots facing upwards. The upper edge of the side plates on opposite sides of the two channel steels is provided with a V-shaped bayonet.

[0015] Beneficial effects

[0016] Compared with the prior art, the advantages of the adjustable mold wedge clamping fixture of the present invention are as follows:

[0017] 1. This fixture utilizes a support plate to support the guide surface below the mold wedge. It works in conjunction with a clamping protrusion that contacts the V-shaped guide surface on the side wall of the mold wedge, and a pressure plate that presses down on the upper surface of the mold wedge. This allows for simultaneous positioning of the mold wedge from above, below, and behind, thus achieving stable clamping of the mold wedge. The lateral position of the support plate can be adjusted via the sliding engagement between the slide rail and the slider; the distance between the support plate and the clamping protrusion can be adjusted via the sliding engagement between the support block and the slider; the tilt angle of the support plate itself can be adjusted via the hinge engagement between the support plate and the support block; the clamping protrusion is detachably connected to the column, allowing for replacement with different specifications of clamping protrusions as needed; and the pressure plate can move vertically.

[0018] Therefore, this tooling can flexibly adjust the left and right positions of the support plate, the distance between the support plate and the clamping protrusion, the tilt angle of the support plate, the specifications of the clamping protrusion, and the horizontal height of the pressure plate according to the specifications and models of the mold wedge, so that the tooling can adapt to the clamping requirements of various specifications and models of standard wedges and has good versatility.

[0019] 2. This fixture utilizes a support plate and a clamping protrusion to simultaneously position and support the lower surface and sides of the die wedge, keeping it horizontal. This ensures the machined surface of the die wedge is perpendicular to the drilling direction of the drill bit, resulting in better perpendicularity during drilling and tapping. Furthermore, the cooperation of the support plate, clamping protrusion, and pressure plate makes this clamping fixture easy to use, enabling quick clamping of the die wedge and improving processing efficiency. This ingenious device is easy to operate, allowing for faster drilling and tapping of die wedges, while also ensuring the perpendicularity of the screw holes or pin holes in the die wedge, thus improving product quality.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0033] Example

[0034] Specific embodiments of the present invention are as follows: Figure 1-7 As shown, an adjustable mold wedge clamping fixture includes a horizontally arranged base plate 1. Two slide rails 2 are horizontally arranged on the upper surface of the base plate 1, and the two slide rails 2 are arranged parallel to each other. For mounting the slide rails 2, a slide rail mounting groove 12 corresponding to the slide rail 2 is provided on the upper surface of the base plate 1, and the slide rail 2 is fixedly mounted in the slide rail mounting groove 12 by a slide rail fixing screw 21 that vertically penetrates the slide rail 2. A slider 3 that can move along its extension direction is provided on the slide rail 2. There are two sliders 3, and the two sliders 2 are arranged sequentially along the extension direction of the slide rail 2. In this embodiment, a slider mounting groove 31 corresponding to the two slide rails 2 is provided on the lower surface of the slider 3. Through the slider mounting groove 31, the slider 3 can be slidably mounted on the slide rail 2, thereby realizing the adjustment of the position of the slider 3.

[0035] The slider 3 has a horizontally movable support block 4 at its top, with the direction of movement perpendicular to the extension direction of the slide rail 2. A vertically swinging support plate 5, with its surface parallel to the slide rail 2, is hinged to the top of the support block 4. A vertical column 6, with its lower end fixed to the base plate 1, is vertically mounted on the side of the support plate 5 away from the support block 4. To position and install the column 6, a column mounting groove 13 is provided on the upper surface of the base plate 1. The column 6 is fixedly installed in the column mounting groove 13 by column mounting screws that pass through the base plate 1 from the lower mesh. Simultaneously, a vertically extending, V-shaped clamping protrusion 7 is detachably installed on the side of the column 6 near the support plate 5. A horizontally movable pressure plate 8, extending towards the support plate 5, is located at the upper end of the column 6.

[0036] Before using this fixture to clamp the mold wedge, it is necessary to flexibly adjust the left and right positions of the support plate 5, the distance between the two support plates 5, the distance between the support plate 5 and the clamping protrusion 7, the tilt angle of the support plate 5, the specifications of the clamping protrusion 7, and the horizontal height of the pressure plate 8 according to the specifications and model of the mold wedge. Specifically: the left and right positions of the support plate 5 and the distance between the two support plates 5 can be adjusted by the sliding fit between the slide rail 2 and the slider 3; the distance between the support plate 5 and the clamping protrusion 7 can be adjusted by the sliding fit between the support block 4 and the slider 3; the tilt angle of the support plate 5 itself can be adjusted by the hinge fit between the support plate 5 and the support block 4; the clamping protrusion 7 is detachably connected to the column 6, and different specifications of clamping protrusion 7 can be replaced as needed; the pressure plate 8 can move up and down.

[0037] When using this tooling to clamp the mold wedge, the support plate 5 supports the guide surface below the mold wedge, and the clamping protrusion 7, which is in close contact with the V-shaped guide surface on the side wall of the mold wedge, and the pressure plate 8, which can press down on the upper end face of the mold wedge, can simultaneously position the mold wedge from above, below and behind, thereby achieving stable clamping of the mold wedge by the tooling.

[0038] Therefore, this fixture can adapt to the clamping requirements of standard wedges of various specifications and models, possessing good versatility. Furthermore, the fixture utilizes the support plate 5 and the clamping protrusion 7 to simultaneously position and support the lower surface and sides of the mold wedge, keeping it horizontal. This ensures that the machined surface of the mold wedge is perpendicular to the drilling direction of the drill bit, resulting in better perpendicularity during drilling and tapping. In addition, the cooperation of the support plate 5, the clamping protrusion 7, and the pressure plate 8 makes this clamping fixture easy to use, enabling quick clamping of the mold wedge and thus improving processing efficiency. This device has a clever structure, is easy to operate, and allows for faster drilling and tapping of mold wedges, while also ensuring the perpendicularity of the screw holes or pin holes of the mold wedge, improving product quality.

[0039] In this fixture, in order to achieve the sliding engagement between the support block 4 and the slider 3, and thus adjust the distance between the support plate 5 and the clamping protrusion 7, as follows: Figure 3 , 4 As shown, the top of the slider 3 is provided with a block mounting groove 32 that extends along the moving direction of the block 4, and the block 4 is slidably mounted above the block mounting groove 32 via a block mounting rail 45 provided on its lower surface. Meanwhile, to achieve the fixation of the support plate 5 and the tightening protrusion 7 after the distance is adjusted, the top of the side wall of the block mounting groove 32 is provided with multiple limiting slots 33 arranged along its extending direction; and the side wall of the block 4 is vertically provided with a locking rail 43, and a locking block 44 is slidably mounted on the locking rail 43. The lower surface of the locking block 44 has a protrusion that engages with the limiting slot 33. When adjusting the distance between the support plate 5 and the tightening protrusion 7, the protrusion of the locking block 44 is located above the limiting slot 33, at which time the position of the block 4 can be slidably adjusted. After the adjustment is completed, simply move the locking block 44 down along the locking rail 43, and engage the protrusion on the lower surface of the locking block 44 with the limiting slot 33.

[0040] In this fixture, the tilt angle of the pallet 5 can be adjusted and fixed. For example... Figure 3 , 4As shown, the support block 4 has a support plate mounting groove 41 that is inclined away from the column 6 and extends perpendicularly to the extension direction of the slide rail 2. A support plate mounting plate extending in the same direction and with its upper edge connected to the lower surface of the support plate 5 is located within the support plate mounting groove 41. A hinge shaft 51 is horizontally threaded through the support plate on the side away from the column 6, with both ends hinged to the side walls of the support plate mounting groove 41. A positioning pin 52 is horizontally threaded through the support plate on the side near the column 6, and at least two support plate positioning holes 42 are provided on both side walls of the support plate mounting groove 41 for the positioning pin 52 to insert into. After adjusting the tilt angle of the support plate 5 using the hinge shaft 51, the tilt angle of the support plate 5 can be fixed by the insertion and engagement of the positioning pin 52 and the support plate positioning holes 42. The position and number of the support plate positioning holes 42 should be based on the commonly used tilt angle of the support plate 5. Furthermore, the opening on the support plate mounting plate for the positioning pin 52 to pass through should be elongated.

[0041] In this embodiment, in order to prevent the positioning pin 52 from coming out, one end of the positioning pin 52 extends through the positioning hole 42 of the support plate to the outside of the support block 4, and the outer wall of the positioning pin 52 located outside the support block 4 is provided with an anti-disengagement groove; the outer wall of the support block 4 is provided with an anti-disengagement tab 53, one end of which overlaps in the anti-disengagement groove and the other end is hinged to the support block 4 by the tab mounting screw 54.

[0042] In this tooling, such as Figure 5 , 6 As shown, to facilitate the replacement of the tightening protrusion 7, a vertical tightening protrusion mounting groove 61 is provided on the side wall of the column 6, extending through the entire column 6. A T-shaped block 71 is provided on the side wall of the tightening protrusion 7 facing the column 6, and is slidably installed in the tightening protrusion mounting groove 61. Through the sliding engagement between the T-shaped block 71 and the tightening protrusion mounting groove 61, the tightening protrusion 7 can be easily and quickly installed / removed from the column 6. In this embodiment, to quickly determine the horizontal height of the tightening protrusion 7, the lower surface of the tightening protrusion 7 abuts against the upper surface of the tightening protrusion limiting step 62 provided on the outer side wall of the column 6.

[0043] In this tooling, such as Figure 5 , 6 As shown, to achieve height adjustment of the pressure plate 8 and its subsequent tightening, a locking block 9 is provided above the pressure plate 8. A screw 91, threaded downwards through the pressure plate 8 and connected to the upper end face of the column 6, is vertically positioned on the lower surface of the locking block 9. Simultaneously, to adjust the position of the pressure plate 8 along its extension direction, a screw through-hole 81 is provided on the pressure plate 8 for the screw 91 to pass through. The screw through-hole 81 is a strip-shaped opening extending in the same direction as the pressure plate 8. In this embodiment, to facilitate tightening the locking block 9, a handle 92 is also horizontally provided on the locking block 9, extending through the entire locking block 9.

[0044] In addition, to facilitate the movement of the tooling, multiple lifting rods 14 are vertically provided at the edge of the upper surface of the substrate 1. The upper part of the lifting rod 14 is bent, and the lower part is threaded to the substrate 1. A nut located above the substrate 1 is also threaded to the outside of the lifting rod 14.

[0045] It is important to note that:

[0046] To facilitate the replacement of the clamping protrusion 7, clamping protrusion placement assemblies 11 for placing spare clamping protrusions 7 are fixed on the upper surface of the base plate 1 on both sides of the column 6. The clamping protrusion placement assembly 11 includes two parallel channel steels with their slots facing upwards, and the upper edge of the side plates on opposite sides of the two channel steels is provided with a V-shaped notch. In this embodiment, in order to place a smaller clamping protrusion 7, two L-shaped steels parallel to the channel steels are also provided between the two channel steels of one set of clamping protrusion placement assemblies 11. The two L-shaped steels are arranged opposite each other, and the upper edge of their side plates is also provided with a V-shaped notch.

[0047] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
