Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold drilling fixture technology, specifically an adjustable mold drilling fixture. Background Technology
[0002] In modern manufacturing, molds are widely used, covering many important fields such as automobiles, electronics, home appliances, and aerospace. The quality and precision of molds directly affect the production efficiency, quality, and cost of products. Drilling, as a common and critical processing step in mold manufacturing, plays a vital role in improving the overall performance of the mold through its precision and efficiency.
[0003] However, existing mold drilling fixtures are often designed for molds of specific shapes and sizes, lacking adaptability to different mold shapes. When processing molds of various shapes, factories often need to equip themselves with multiple fixtures of different specifications. This not only increases equipment procurement costs but also occupies a large amount of storage space. Furthermore, frequent fixture changes can lead to reduced production efficiency. During drilling, the mold needs to be firmly fixed to prevent displacement or shaking caused by the rotation of the drill bit and cutting forces. However, some existing fixtures cannot guarantee a consistently stable clamping effect when dealing with complex mold shapes or during long-term drilling operations, easily leading to mold loosening, which in turn affects drilling accuracy and may even cause the mold to be scrapped, increasing production costs.
[0004] In view of this, we propose an adjustable fixture for drilling molds. Utility Model Content
[0005] The purpose of this utility model is to provide an adjustable mold drilling fixture, which solves the problem that existing mold drilling fixtures are often designed for molds of specific shapes and sizes and lack adaptability to molds of different shapes.

[0014] By employing the above technical solution, this utility model provides an adjustable fixture for drilling molds. It possesses at least the following beneficial effects:
[0015] (1) By setting the movable components, the present invention controls the motor to drive the fixed rod to rotate together when it works, and slides with the rotation of the fixed rod. The movable block hinged at the top of the movable rod slides at the bottom of the fixed frame towards the surface of the processing table. When the movable block slides, it will drive the top turntable, connecting plate and clamping shaft to slide. When the clamping shaft slides, it can clamp the surface of molds of different shapes and perform a surrounding clamping action on the mold from different directions and angles to prevent the mold from shifting or shaking during the drilling process, thereby adapting to the shape contour of molds of different shapes, achieving stable clamping and improving work quality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0025] An adjustable fixture for drilling molds, such as Figures 1-3 As shown, the machine includes a machine base 1, a slider 2 slidably connected to the top of the machine base 1, a telescopic cylinder 3 fixedly mounted on the surface of the slider 2, a support plate 4 fixedly mounted on the surface of the telescopic cylinder 3, a drive motor 5 fixedly mounted on the top of the support plate 4, and a drill bit 6 fixedly mounted on the surface of the output shaft of the drive motor 5. The drill bit 6 is rotatably connected to the bottom of the support plate 4.
[0026] It also includes an active component 7, used for clamping and adjusting molds of different shapes;
[0027] The movable component 8 is used to adjust the resistance of the mold during drilling;
[0028] First, the movable component 7 includes: a fixed frame 71, which is fixedly installed on the top of the machine base 1. A processing table 72 is fixedly installed on the top of the fixed frame 71. A control motor 73 is fixedly installed on the top of the machine base 1. A fixed rod 74 is fixedly installed on the surface of the output shaft of the control motor 73. A movable rod 75 is hinged to the bottom of the fixed rod 74. A movable block 76 is hinged to the top of the movable rod 75. The movable block 76 is slidably connected to the bottom of the fixed frame 71. A turntable 77 is rotatably connected to the bottom of the movable block 76. The adjustment of the clamping shaft 79 can be achieved by rotating the turntable 77.
[0029] Secondly, a connecting plate 78 is fixedly installed on the surface of the turntable 77, and a clamping shaft 79 is rotatably connected to the surface of the connecting plate 78. The clamping stability can be improved by the clamping shaft 79 forming a triangular shape with the connecting plate 78.
[0030] In this embodiment, by setting the movable component 7, the motor 73 drives the fixed rod 74 to rotate together when it works, and slides as the fixed rod 74 rotates. The movable block 76, which is hinged to the top of the movable rod 75, slides at the bottom of the fixed frame 71 towards the surface of the processing table 72. When the movable block 76 slides, it will drive the top turntable 77, the connecting plate 78 and the clamping shaft 79 to slide. When the clamping shaft 79 slides, it can clamp the surface of molds of different shapes and perform a surrounding clamping action on the mold from different directions and angles to prevent the mold from shifting or shaking during the drilling process, thereby adapting to the shape contour of molds of different shapes, achieving stable clamping and improving work quality. Example 2
[0031] like Figures 4-5 As shown, the movable component 8 includes: a connecting block 81, which is fixedly installed on the top of the movable block 76, and a fixing block 82 is fixedly installed inside the connecting block 81. A clamping plate 83 is slidably connected inside the fixing block 82.
[0032] Furthermore, a fixing spring 84 is fixedly installed on the inner side of the clamping plate 83. The fixing spring 84 is fixedly installed inside the fixing block 82. The fixing spring 84 on the inner side of the clamping plate 83 can achieve the effect of resetting when the clamping plate 83 is abutted.
[0033] Furthermore, a toothed plate 85 is fixedly installed on the top of the clamping plate 83, and a support rod 86 is hinged to the outside of the clamping plate 83. The support rod 86 is slidably connected to the surface of the connecting block 81. An insert plate 87 is hinged to the top of the connecting block 81. A spiral spring 88 is fixedly installed on the surface of the insert plate 87, and an insert block 89 is fixedly installed at the bottom of the insert plate 87. The insert block 89 is inserted into the top of the toothed plate 85. The spiral spring 88 on the surface of the insert plate 87 can be used to drive the insert plate 87 to reset.
[0034] Finally, two sets of movable components 8 are provided, and both sets of movable components 8 are symmetrically arranged with the center line of the fixed frame 71 as the axis of symmetry. The two sets of movable components 8 ensure that the mold is subjected to uniform force during drilling and will not shift. The cross-section of the movable block 76 is U-shaped. The U-shaped movable block 76 improves the connection between the movable block 76 and the turntable 77. The surface of the fixed frame 71 has a strip groove 710, which improves the connection between the movable block 76 and the connecting block 81. The surface of the connecting block 81 has a sliding groove 810, which allows the support rod 86 to slide on the surface of the connecting block 81, thus achieving a stable movement of the clamping plate 83.
[0035] In this embodiment, by setting the movable component 8, after the mold is placed, the sliding of the movable block 76 will also drive the movement of the connecting block 81, the fixing block 82, and the clamping plate 83, and clamp them on the surface of the mold. After the clamping plate 83 is clamped, the clamping plate 83 abuts against the mold under the action of the fixing spring 84, playing a preliminary fixing role. When the clamping plate 83 slides, it will also drive the toothed plate 85 to slide. When the toothed plate 85 slides, it will first abut against the surface of the insert block 89, and by abutting the insert block 89, it will drive the insert plate 87 to swing upward. After the clamping plate 83 stably clamps the mold, the insert plate 87 will reset under the action of the spiral spring 88, thereby driving the insert block 89 to reset and re-insert into the surface of the toothed plate 85 for fixing, thereby locking the position of the clamping plate 83, preventing the clamping plate 83 from sliding at will, further stabilizing the abutment and fixing of the mold, improving the stability of the mold fixing, and speeding up the work efficiency.
[0036] In use, the adjustable mold drilling fixture of this utility model has a machine base 1 as the basic support structure of the entire fixture. The slider 2, which is slidably connected to the top of the machine base 1, can move along the surface of the machine base 1 in a specific direction. The telescopic cylinder 3, which is fixedly installed on the slider 2, can extend and retract. The telescopic cylinder 3 drives the support plate 4 connected to it to move, and the drive motor 5 fixed on the top of the support plate 4 also changes position accordingly. When the drive motor 5 starts, its output shaft drives the fixed drill bit 6 to rotate at high speed. The drill bit 6 is rotatably connected to the bottom of the support plate 4. Through the extension and retraction of the telescopic cylinder 3 and the sliding of the slider 2, the rotating drill bit 6 can be accurately positioned above the position of the hole to be drilled in the mold, preparing for subsequent drilling. When used for clamping and adjusting molds of different shapes, the fixing frame 71 is fixed on the top of the machine base 1 to provide stable support for the entire movable component 7. The processing table 72 on the top is the part where the mold is placed. When the control motor 73 installed on the top of the machine tool 1 is working, its output shaft rotates, causing the fixed rod 74 to rotate together. The movable rod 75, which is hinged at the bottom of the fixed rod 74, slides as the fixed rod 74 rotates. The movable block 76, which is hinged at the top of the movable rod 75, slides at the bottom of the fixed frame 71 towards the surface of the processing table 72. When the movable block 76 slides, it will drive the top turntable 77, connecting plate 78 and clamping shaft 79 to slide. When the clamping shaft 79 slides, it can clamp the surface of molds of different shapes and perform a surrounding clamping action on the molds from different directions and angles to prevent the molds from shifting or shaking during the drilling process. This adapts to the shape contour of molds of different shapes, achieves stable clamping, and improves work quality.
[0037] After the mold is placed, the sliding of the movable block 76 will also drive the movement of the connecting block 81. When the connecting block 81 moves, it will drive the movement of the fixed block 82 and the clamping plate 83, which will clamp onto the surface of the mold. After the clamping plate 83 is clamped, the fixing spring 84 applies an inward elastic force to the clamping plate 83. Under the action of the fixing spring 84, the clamping plate 83 abuts against the mold, playing a preliminary fixing role. When the clamping plate 83 abuts against the mold, it will slide inside the fixed block 82 and drive the top toothed plate 85 to slide. When the toothed plate 85 slides, it will first abut against the surface of the insert block 89, and by abutting the insert block 89, it will drive the insert plate 87 to swing upward. After the clamping plate 83 stably clamps the mold, the insert plate 87 will reset under the action of the spiral spring 88, thereby driving the insert block 89 to reset, so that the insert block 89 is re-inserted into the surface of the toothed plate 85 for fixing, thereby locking the position of the clamping plate 83, preventing the clamping plate 83 from sliding at will, further stabilizing the abutment and fixing of the mold, improving the stability of the mold fixing, and speeding up the work efficiency.
