Description

Technical Field

[0001] This utility model relates to the technical field of mold processing, specifically to auxiliary tooling for milling inclined holes in molds. Background Technology

[0002] Molds are an important basic process equipment in the manufacturing industry. They are mainly used for the efficient and mass production of relevant parts and components in industrial products and are an important part of the equipment manufacturing industry.

[0003] In mold making, it is often necessary to machine holes, such as straight holes and angled holes. Machining straight holes is relatively easy; simply ensure that the machining surface of the mold is perpendicular to the cutting tool, and the tool feeds vertically. However, machining angled holes requires the use of tooling to assist in positioning the mold, making it easier for the cutting tool to drill and mill the angled hole. For example, the existing technology "Angled Hole Machining Fixture" (publication number: CN209902713U) discloses a positioning fixture. By aligning the positioning surface of the fixture with the machining surface of the workpiece, and with the positioning surface at a certain angle to the central axis of the hole being machined, the cutting tool can machine the angled hole simply by feeding horizontally. However, the existing technology still has the following technical problems:

[0004] In existing technologies, the workpiece needs to be fixed horizontally on the fixture, and the machining conditions must ensure that the cutting tool can enter from a horizontal direction to machine the inclined hole. However, in actual production, such production conditions cannot be fully guaranteed. This is because the equipment that can adjust the angle and direction of the drilling and milling tool is relatively expensive and cannot be equipped on the entire production line. Therefore, the cutting tools of most drilling and milling equipment are generally set in a vertical direction, which makes the machining fixtures in the existing technology unusable. At the same time, the workpiece in the existing technology also needs to be fixed in the mounting hole of the fixture, which is only applicable to one type of workpiece and cannot be used for larger or smaller workpieces, resulting in poor versatility. Utility Model Content

[0005] This utility model provides an auxiliary tooling for milling inclined holes in molds, which can solve the problem that the existing inclined hole machining fixtures cannot be adapted to most vertical milling and drilling equipment and cannot be used for workpieces of various sizes, resulting in poor versatility.

[0006] This application provides the following technical solution: an auxiliary tooling for milling inclined holes in a mold, including a tooling table and an angle limiting component and a position limiting component fixed on the tooling table; the position limiting component includes a first abutment block and a second abutment block fixed on the tooling table, the adjacent ends of the first abutment block and the second abutment block forming a 90-degree angle; the angle limiting component includes a side pad block and a middle pad block fixed on the tooling table; the middle pad block is located between the side pad block and the first abutment block, the top surfaces of the side pad block and the middle pad block are inclined surfaces, and the inclination direction of the inclined surfaces gradually increases along the opening direction of the angle between the first abutment block and the second abutment block.

[0007] Beneficial effects:

[0008] Improve the stability and versatility of mold drilling and milling. Since the top surfaces of the side pads and the central pad are inclined, and the inclination direction gradually increases along the angle between the first and second abutment blocks, when the mold is placed on the side pads and the central pad, it is in an inclined state with one side higher than the other. This means that the hole drilled vertically downwards by the tool is an inclined hole relative to the mold, thus making it suitable for various vertical drilling and milling equipment, improving versatility. Furthermore, the adjacent ends of the first and second abutment blocks form a 90-degree angle. This angle serves two purposes: firstly, it provides abutment and positioning for the two side walls of the inclined mold, improving stability during drilling and milling; secondly, the 90-degree angle arrangement allows for abutment and positioning of molds of more sizes, further enhancing the tooling's versatility.

[0009] Furthermore, the long side of the side pad is arranged parallel to the side of the tooling table, and the middle pad is arranged parallel to the first abutment block.

[0010] Beneficial effects: The installation positions of the side pads and the center pads on the tooling table are limited to adapt to the shape of the mold and improve the stability of mold positioning.

[0011] Furthermore, the sidewall within the angle between the first abutment block and the second abutment block is an inclined surface, and the inclination direction of the inclined surface gradually decreases from the bottom of the first abutment block or the second abutment block towards the top.

[0012] Beneficial effects: Since the side pads and the middle pads cause the mold to be in an inclined state, the two side walls of the mold near the first abutment block and the second abutment block will also be in an inclined state. Therefore, the side wall surface within the included angle of the first abutment block and the second abutment block is set as an inclined surface. In order to fit with the two side wall surfaces of the mold, the stability of the mold positioning is effectively improved.

[0013] Furthermore, the side pad, the middle pad, the first abutment block and the second abutment block are all provided with pin holes and screw holes, and the pin holes and screw holes are spaced apart. The pin holes are provided with positioning pins and the screw holes are provided with screws.

[0014] Beneficial effects: When installing the various pads and abutments onto the tooling table with screws, the locating pins can achieve limiting, eliminate gap errors during screw connection, and improve installation accuracy.

[0015] Furthermore, a through-hole group is provided on the tooling table between the side pad and the middle pad, the through-hole group including a first through-hole, a second through-hole, a third through-hole and a fourth through-hole arranged adjacent to each other.

[0016] Beneficial effects: The drilling and milling cutter drills holes in the mold vertically downwards. After the mold is drilled through, the drilling cutter can enter the through hole group, which can ensure that the mold is drilled through while avoiding the drilling cutter and preventing the cutter from touching the tooling table and causing wear.

[0017] Furthermore, the bottom surfaces of the side pads, the middle pads, the first abutting block, and the second abutting block are also provided with pads.

[0018] Beneficial effects: By setting shims at the bottom of each pad and abutment block, the number of shims can be increased or decreased to adjust the angle of the inclined surface of each pad and abutment block, so as to adapt to various different inclined hole angle requirements and improve applicability.

[0019] Furthermore, the tooling table can also be detachably connected to a disassembly and assembly plate, and the through hole group is set on the disassembly and assembly plate.

[0020] Beneficial effects: Setting the through-hole assembly on the disassembly plate makes it easy to set up multiple disassembly plates with different hole positions for backup. It also allows for the replacement of the disassembly plate according to the drilling and milling hole position requirements of different molds, thus improving applicability. Attached Figure Description

[0021] Figure 1 This is a top view of Embodiment 1 of the present utility model.

[0022] Figure 2 This is a top view of Example 3. Detailed Implementation

[0023] The following detailed description illustrates the specific implementation method:

[0024] The markings in the accompanying drawings include: tooling table 1, side pad 2, first through hole 3, second through hole 4, third through hole 5, fourth through hole 6, center pad 7, first abutment block 8, second abutment block 9, screw hole 91, pin 92, included angle opening 10, disassembly plate 11, and protrusion 12.

[0025] Example 1

[0026] like Figure 1 As shown, the auxiliary tooling for milling inclined holes in molds includes a tooling table 1 and angle limiting components and position limiting components fixed on the tooling table 1.

[0027] The position limiting component includes a first abutment block 8 and a second abutment block 9 fixed on the tooling table 1. The adjacent ends of the first abutment block 8 and the second abutment block 9 form a 90-degree angle. The side wall surface within the angle between the first abutment block 8 and the second abutment block 9 is an inclined surface, and the inclination direction of the inclined surface gradually decreases from the bottom of the first abutment block 8 or the second abutment block 9 towards the top.

[0028] The angle limiting component includes a side pad 2 and a middle pad 7 fixed on the tooling table 1. The middle pad 7 is located between the side pad 2 and the first abutment block 8. The top surfaces of the side pad 2 and the middle pad 7 are inclined surfaces, and the inclination direction of the inclined surfaces gradually increases along the included angle opening 10 between the first abutment block 8 and the second abutment block 9. When the mold is placed on the side pad 2 and the middle pad 7, the mold is in an inclined state with one side higher than the other. The long side of the side pad 2 is parallel to the side of the tooling table 1, and the middle pad 7 is parallel to the first abutment block 8 to adapt to the shape of the mold and improve the stability of the mold positioning.

[0029] The side pad 2, the middle pad 7, the first abutment block 8, and the second abutment block 9 are all provided with pin holes 92 and screw holes 91, and the pin holes 92 and screw holes 91 are spaced apart. The pin holes 92 contain locating pins 92, and the screw holes 91 contain screws for connecting and fixing the various pads and abutment blocks. When the various pads and abutment blocks are installed onto the tooling table 1 with screws, the locating pins 92 can achieve limiting, eliminating gap errors during screw connection and improving installation accuracy.

[0030] A set of through holes is provided on the tooling table 1 between the side pad 2 and the central pad 7. The set of through holes includes a first through hole 3, a second through hole 4, a third through hole 5, and a fourth through hole 6 arranged adjacent to each other. The second through hole 4 is a gourd-shaped hole. When the drilling and milling cutter drills vertically downwards into the mold, after the mold is drilled through, the drilling and milling cutter can enter the set of through holes. This ensures that the mold is effectively drilled through while avoiding the drilling and milling cutter, preventing the cutter from touching the tooling table 1 and causing wear.

[0031] The usage method of this tooling is as follows:

[0032] The mold is placed on the side pad 2 and the middle pad 7, with the two side walls of the mold abutting against the two side walls of the first abutting block 8 and the second abutting block 9, respectively, thus completing the mold placement. Since the side pad 2 and the middle pad 7 cause the mold to be in an inclined state, the two side walls of the mold near the first abutting block 8 and the second abutting block 9 will also be in an inclined state. Therefore, the side wall within the included angle of the first abutting block 8 and the second abutting block 9 is set as a slope to facilitate contact with the two side walls of the mold, improving the stability of the mold during positioning.

[0033] The top surfaces of the side pad 2 and the middle pad 7 are inclined surfaces, and the inclination direction of the inclined surfaces gradually increases along the angle opening 10 between the first abutment block 8 and the second abutment block 9. This makes the mold in an inclined state with one side higher than the other when it is placed on the side pad 2 and the middle pad 7. In this way, the hole drilled vertically from above by the tool is an inclined hole relative to the mold, which can be used by various drilling and milling equipment for vertical processing. The adjacent ends of the first abutment block 8 and the second abutment block 9 form a 90-degree angle. On the one hand, it can abut and position the two side walls of the inclined mold, improving the stability of the mold during drilling and milling. On the other hand, the arrangement of the 90-degree angle can ensure that molds of more sizes can be abutted and positioned, improving the versatility of the tooling.

[0034] Example 2

[0035] The difference between this embodiment and Embodiment 1 is that the bottom surfaces of the side pad 2, the middle pad 7, the first abutment block 8, and the second abutment block 9 are also provided with shims. By providing shims at the bottom of each pad and abutment block, the number of shims can be increased or decreased to adjust the angle of the inclined surfaces of each pad and abutment block, thus adapting to various different inclined hole angle requirements and improving applicability.

[0036] Example 3

[0037] The difference between this embodiment and embodiments one and two is that the tooling table 1 may also be provided with a disassembly plate 11, and a through-hole group is set on the disassembly plate 11. The tooling table 1 and the disassembly plate 11 are connected in such a way that the tooling table 1 is provided with a stepped through hole, and the edge shape of the disassembly plate 11 fits the stepped through hole. Therefore, after the disassembly plate 11 is inserted into the stepped through hole of the tooling table 1, the upper surface of the disassembly plate 11 is flush with the upper surface of the tooling table 1. At the same time, the edge of the disassembly plate 11 is also provided with an integrally formed protrusion 12, which is used to circumferentially limit the disassembly plate 11 and prevent the disassembly plate 11 from rotating. Setting the through-hole group on the disassembly plate 11 makes it convenient to set multiple disassembly plates 11 with different hole positions for backup, and it is also possible to replace the disassembly plate 11 according to the drilling and milling hole position requirements of different molds, thereby improving applicability.
