It is only for the convenience of description and simplified description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0031] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of elements other than the listed elements and may also include additional elements not specifically listed.

[0032] See also Figures 1-12 The present invention discloses an inclined hole processing positioning fixture 100 for positioning a mold processing part 200 so as to open an inclined hole 240 on the mold processing part 200 .

[0033] See also Figure 1 、 Figure 2 and Figure 11 The inclined hole processing positioning fixture 100 has a first positioning surface 110 and a second positioning surface 120 connected to each other, and the mold processing part 200 has a first contact surface 210 and a second contact surface 220 connected to each other. When the mold processing part 200 is placed on the inclined hole processing positioning fixture 100, the first contact surface 210 abuts against the first positioning surface 110, and the second contact surface 220 abuts against the second positioning surface 120. The inclined hole processing positioning fixture is also provided with an avoidance hole 140, which is arranged in the vertical direction. When the mold processing part 200 is positioned in the inclined hole When processing the positioning jig 100, the inclined hole 240 opened on the mold processing part 200 is arranged in the vertical direction, and the inclined hole 240 is coaxial with the avoidance hole 140 and is connected to each other. The vertical arrangement of the inclined hole 240 and the avoidance hole 140 facilitates the operation of the punching equipment, and can effectively avoid the angle adjustment operation and poor accuracy problems caused by oblique punching. By setting the avoidance hole 140, the drill bit of the punching equipment can pass through the inclined hole 240 as a whole, which not only facilitates the punching operation, but also allows the debris generated by the punching to fall through the avoidance hole 140 and be collected in the waste box.

[0034] See also Figure 1 and Figure 2 The cross-sectional area of ​​the avoidance hole 140 is greater than or equal to the cross-sectional area of ​​the inclined hole 240. In this embodiment, the radius of the avoidance hole 140 is three times the radius of the inclined hole 240, which not only reserves sufficient operating space for the drill bit of the drilling equipment, but also facilitates the removal of debris generated by drilling.

[0035] See also Figure 2 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 11The side wall of the oblique hole processing positioning jig 100 located on the second positioning surface 120 is provided with a positioning hole 150, and the mold processing part 200 is recessed with a threaded fixing hole 250 on the second contact surface 220. In this embodiment, the mold processing part 200 is fixed to the oblique hole processing positioning jig 100 by passing a fixing bolt through the positioning hole 150 and screwing it into the fixing hole 250. This can effectively prevent the vibration generated during the punching operation from causing the oblique hole processing positioning jig 100 and the mold processing part 200 to be relatively displaced, resulting in drilling offset, and ultimately causing poor drilling operation. In this embodiment, the screw connection setting is not only stable, but also more precise positioning. In other embodiments, the positioning method of the positioning hole 150 and the fixing hole 250 can be positioned by inserting a pin. Although quick disassembly and assembly can be achieved, attention should be paid to the displacement problem caused by the vibration generated during the punching process. Furthermore, in this embodiment, there are two positioning holes 150 and two fixing holes 250, which are arranged corresponding to each other; in other embodiments, there can be three positioning holes 150 and three fixing holes 250, which are arranged corresponding to each other. By setting a plurality of positioning holes 150 and fixing holes 250 that are arranged corresponding to each other, the mold processing part 200 and the inclined hole processing positioning jig 100 can be further stabilized, thereby greatly improving the punching accuracy.

[0036] See also Figure 1 、 Figure 2 and Figure 12 The inclined hole machining and positioning jig 100 further includes a reference surface 130 connected to the second positioning surface 120, and the mold workpiece 200 further includes a reference surface 230 connected to the second contact surface 220. When the mold workpiece 200 is positioned on the inclined hole machining and positioning jig 100, the reference surface 130 and the reference surface 230 are located in the same plane. In this embodiment, by detecting whether the reference surface 130 and the reference surface 230 are located in the same plane, it is confirmed whether the first positioning surface 110 and the first contact surface 210 are completely aligned, thereby further ensuring that the inclined hole 240 formed in the mold workpiece 200 is more accurately formed.

[0037] Please continue reading Figure 12 In this embodiment, the first positioning surface 110 and the reference surface 130 are arranged parallel to each other; the second positioning surface 120 and the first positioning surface 110 are arranged perpendicular to each other; the second positioning surface 120 and the reference surface 130 are arranged perpendicular to each other.

[0038] See also Figure 2 and Figure 11In this embodiment, the first positioning surface 110 and the first contact surface 210 are mutually fitting planes. In other embodiments, the first positioning surface 110 and the first contact surface 210 may also be mutually fitting curved surfaces.

[0039] Or the first positioning surface 110 and the first contact surface 210 have a mutually cooperating positioning structure, wherein the first positioning surface 110 has a positioning protrusion, and the first contact surface 210 has a positioning groove that cooperates with the positioning protrusion; or the first positioning surface 110 has a positioning groove, and the first contact surface 210 has a positioning protrusion that cooperates with the positioning groove. By setting the positioning structure of the positioning protrusion and the positioning groove, the position of the mold processing part 200 on the inclined hole processing positioning jig 100 can also be made more precise, and the inclined hole 240 opened by the punching equipment is finally more accurate.

[0040] See also Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 8 and Figure 12 The oblique hole machining positioning jig 100 has a positioning portion 160 extending laterally, and the oblique hole machining positioning jig 100 is fixed to the workbench via the positioning portion 160. Furthermore, the fixing portion 160 has a fixing slot 161. In this embodiment, the oblique hole machining positioning jig 100 is fixed to the workbench by fastening bolts passing through the fixing slot 161.

[0041] The oblique hole processing positioning jig 100 of the present invention ensures that the mold processing part 200 is accurately positioned on the oblique hole processing positioning jig 100 by means of the first positioning surface 110 and the first contact surface 210, the second positioning surface 120 and the second contact surface 220 that cooperate with each other, and the reference surface 130 and the reference surface 230 that serve as positioning references. The mold processing part 200 is further secured to the oblique hole processing positioning jig 100 by means of a fixing bolt that passes through the positioning hole 150 and is screwed into the fixing hole 250, thereby ensuring that the oblique hole 240 is vertically arranged and connected to the avoidance hole 140. As a result, the punching equipment can achieve extremely high accuracy in drilling the oblique hole 240 on the mold processing part 200. Therefore, the yield rate of products produced by the mold processing part 200 with the extremely high accuracy of the oblique hole 240 installed in the mold is greatly improved, which in turn saves costs for the enterprise and is deeply loved by the enterprise.

[0042] The inclined hole processing and positioning jig 100 provided by the present invention not only greatly improves the accuracy of the inclined hole 240 opened, but also ensures the yield rate of the product.

[0043] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the scope of protection of the present invention.
