Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, specifically to a fixture for machining angled holes. Background Technology

[0002] Injection molds often require sliding parts, and sometimes, due to location or structural limitations, screws need to be locked at an angle. Therefore, the mold blank needs to be tapped with corresponding angled threads. Larger mold blanks typically require lifting screw holes on all four sides. The conventional approach is: 1. When tapping the angled threads, use shims or wedges to ensure the mold blank meets the machining angle. 2. Machining the lifting screw holes on the four sides of the mold blank requires using two clamps to hold both sides during machining, and tapping the threads on all four sides requires four separate clamping and disassembly operations to complete the machining.

[0003] According to existing technical practices, tapping the lifting screw holes on multiple sides of the mold blank requires frequent changes of clamping and disassembly to complete the process, which is very time-consuming and laborious. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings and deficiencies in the existing technology and provide a fixture for machining angled holes.

[0005] One embodiment of this utility model provides a fixture for machining angled holes, comprising:

[0006] A fixing base, wherein a fixing post is provided on the fixing base;

[0007] The fixture body has a blank clamping part and multiple assembly holes. The blank clamping part is used to clamp the blank to be processed. The angle between the extension direction of different assembly holes and the vertical direction is different. The fixture body is rotatably engaged with the fixed column through one of the assembly holes.

[0008] In some alternative embodiments, the angle between the mounting hole and the vertical direction is not greater than 45° and not less than 0°.

[0009] In some alternative embodiments, the angle between the mounting hole and the vertical direction is 0°, 16°, 20°, 25° or 30°.

[0010] In some alternative embodiments, the blank clamping part is a magnet disposed on one side of the clamp body.

[0011] In some alternative embodiments, a mounting groove is formed on one side of the clamp body, and the magnet is mounted in the mounting groove.

[0012] In some alternative embodiments, two protruding fixing structures are formed on one side of the clamp body, and the mounting groove is formed between the two fixing structures.

[0013] In some alternative embodiments, the fixing structure includes an upper fixing arm and a lower fixing arm, and the mounting groove is formed between the upper fixing arm and the lower fixing arm of the two fixing structures.

[0014] In some alternative embodiments, the clamp body is provided with a plurality of locking bolts, which are locked in place with the magnet.

[0015] In some alternative embodiments, a plurality of locking bolts are provided on the upper and lower fixing arms of one of the fixing structures, and the locking bolts are locked in place with the magnet.

[0016] Compared to existing technologies, the angled hole machining fixture of this utility model can assemble the corresponding assembly hole on the fixture body with the fixed post according to the angle that the mold blank needs to be machined, so that the fixture body maintains the corresponding angle, thereby positioning the mold blank clamped on the fixture body at the corresponding angle, so as to facilitate the tapping equipment to perform machining. Furthermore, the fixture body can rotate relative to the fixed post, thereby adjusting the direction of the fixture body to tap different positions of the mold blank, reducing the need for frequent disassembly and assembly of the mold blank in existing technologies.

[0030] Please see Figures 1 to 4 This invention provides a fixture for machining angled holes, comprising:

[0031] Fixed base 10, and fixed post 11 is provided on fixed base 10;

[0032] The fixture body 20 is provided with a blank clamping part 21 and multiple assembly holes 22. The blank clamping part 21 is used to clamp the blank to be processed. The angle between the extension direction of different assembly holes 22 and the vertical direction is different. The fixture body 20 is rotatably engaged with the fixed column 11 through one of the assembly holes 22.

[0033] The working principle of a slanted hole machining fixture according to one embodiment of this utility model is explained below:

[0034] Please see Figures 5 to 6 According to the angle at which the die blank needs to be tapped, the corresponding mounting hole 22 on the fixture body 20 is selected to rotate and engage with the fixing post 11, so that the fixture body 20 maintains the corresponding angle, and the die blank is clamped by the die blank clamping part 21, thereby positioning the die blank at the corresponding angle. The fixture body 20 can rotate relative to the fixing post 11, so that the fixture body 20 can adjust its position, so that the tapping equipment can process different positions of the die blank, avoiding the situation in the prior art that requires frequent disassembly and assembly of the die blank and fixture to adjust the angle and position of the die blank.

[0035] In some optional embodiments, the angle between the mounting hole 22 and the vertical direction is not greater than 45° and not less than 0°. Different angles of the mounting holes 22 are used to accommodate the different tapping requirements of the die blank. The angle between the mounting hole 22 and the vertical direction can be designed according to actual needs. For example, in some optional embodiments, the angle between the mounting hole 22 and the vertical direction is 0°, 16°, 20°, 25°, 30°, 35°, 40°, or 45°. In this embodiment, the fixture body 20 is provided with 5 mounting holes 22, and the angles between the 5 mounting holes 22 and the vertical direction are 0°, 16°, 20°, 25°, and 30°, respectively.

[0036] In some alternative embodiments, the blank clamping part 21 is a magnet disposed on one side of the fixture body 20, which attracts the blank to achieve clamping. Of course, the blank clamping part 21 can also adopt other suitable structures, such as the blank clamping part 21 including two movable clamping plates, which cooperate to clamp the blank to achieve blank clamping.

[0037] In some alternative embodiments, a mounting groove 23 is formed on one side of the clamp body 20, and the magnet is mounted in the mounting groove 23 to facilitate the installation of the magnet.

[0038] In some alternative embodiments, two protruding fixing structures 24 are formed on one side of the clamp body 20, and a mounting groove 23 is formed between the two fixing structures 24. The fixing structures 24 facilitate the formation of the mounting groove 23 to facilitate the assembly of the magnet.

[0039] In some alternative embodiments, the fixing structure 24 includes an upper fixing arm 25 and a lower fixing arm 26, and the mounting groove 23 is formed between the upper fixing arm 25 and the lower fixing arm 26 of the two fixing structures 24. The fixing structure 24 is divided into an upper fixing arm 25 and a lower fixing arm 26. When the magnet is relatively thick, the upper fixing arm 25 and the lower fixing arm 26 are spaced a certain distance apart, which helps to reduce the weight of the fixing structure 24.

[0040] In some optional embodiments, the clamp body 20 is provided with a plurality of locking bolts 27, which are locked in place with the magnets, thereby enabling the detachable installation of the magnets. The magnets can also be selected to conform to the shape of the mold blank, thereby better fitting the mold blank. In this embodiment, a plurality of locking bolts 27 are provided on the upper fixing arm 25 and the lower fixing arm 26 of one of the fixing structures 24. The locking bolts 27 are locked in place with the magnets. The presence of locking bolts 27 on both the upper fixing arm 25 and the lower fixing arm 26 improves the locking stability.

[0041] In this embodiment, both the upper fixed arm 25 and the lower fixed arm 26 are provided with recesses 28, and the caps of the locking bolts 27 can be hidden in the recesses 28.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
