Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically an adjustable fixing tool for drilling holes in molds. Background Technology

[0002] In industrial production, molds are key basic equipment for product forming, and their processing accuracy directly determines the quality of the final product. The drilling process is an important part of mold manufacturing, which requires high-precision machining of through holes and blind holes in the mold blank. The stable fixation of the mold during the drilling process is the core prerequisite for ensuring processing accuracy.

[0003] Traditional tooling clamping mechanisms are mostly specialized structures designed for specific mold shapes, such as right-angle clamps for square molds and arc-shaped slots for round molds. When machining molds of different shapes (such as irregular curved surfaces or irregular contours), the entire clamping assembly needs to be replaced, which is not only cumbersome but also reduces production efficiency due to frequent replacements and increases tooling inventory costs. Although some general-purpose tooling attempts to use adjustable clamps, the adjustment range of the clamps is limited, and the clamping stability for asymmetrical molds is insufficient. They are prone to lateral displacement under drilling vibration, resulting in hole diameter deviation or hole position offset. Mold drilling often requires machining non-perpendicular hole systems such as oblique holes and irregular holes according to design requirements. Traditional tooling is mostly a fixed platform structure, which can only realize the translation adjustment of the mold on the horizontal plane and cannot adjust the rotation angle around the X and Y axes. If it is necessary to process holes with an inclined angle, the mold posture must be manually adjusted by means of shims, wedges, etc. This not only results in low angle adjustment accuracy (error > 2°) but also poor fixing reliability, posing a risk of mold overturning and severely restricting the processing quality of complex hole systems.

[0004] Therefore, this utility model provides an adjustable fixing fixture for drilling holes in molds. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the problems mentioned in the background art, an adjustable fixing fixture for die punching is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An adjustable fixing fixture for drilling molds, comprising a base plate; legs fixedly installed on both sides of the bottom of the base plate; a rectangular block movably installed on the top of the base plate; a clamping mechanism provided on the top of the rectangular block; an adjustment component provided on one side of the clamping mechanism; a support component provided on the top of the rectangular block; a fixing mechanism provided on the bottom of the base plate; a rotating mechanism provided on the inner wall of the rectangular block; the clamping mechanism comprising a side plate, a first screw, and a clamping block; four sets of side plates are provided, fixedly installed on the top of the rectangular block; several sets of first screws are provided, sliding laterally on the inner wall of the side plates; one end of the first screw is fixedly installed with the clamping block; the combined use of the side plate, the first screw, and the clamping block can achieve clamping of the mold through the drive of the adjustment component; simultaneously, the individual design of multiple sets of first screws can adapt to different concave depths of the mold, thereby enabling clamping of different molds.

[0007] Preferably, the adjustment component includes a slot and a knob. The slot is annularly formed on the surface of the first screw. Several sets of knobs are provided, and the sets of knobs are laterally rotatable on the side plate away from the clamping block. The knobs are threadedly connected to the first screw. In this scheme, the cooperation of the slot and the knob allows the user to conveniently drive the first screw to move to one side. The slot allows the side plate to clamp the first screw, so that the first screw can only move laterally and will not rotate.

[0008] Preferably, the support component includes a support platform and a slot. The support platform is fixedly installed on the top of the rectangular block, and the slot is provided on the surface of the support platform. In this solution, the cooperation between the support platform and the slot allows the user to accurately place the mold on the platform without having to deliberately place it.

[0009] Preferably, the fixing mechanism includes a servo motor, a second screw, and a first friction disk. The servo motor is fixedly installed at the bottom of the base plate, and the second screw is fixedly installed at the output end of the servo motor and passes through the base plate. The surface of the second screw is threadedly connected to the first friction disk. In this scheme, the cooperation of the servo motor, the second screw, and the first friction disk can drive the first friction disk to move upward under the user's control. When the first friction disk rises, it will press against the second friction disk and generate friction with it to fix the second friction disk.

[0010] Preferably, the rotating mechanism includes a second friction disc, a sleeve, a bearing, and a connecting plate. The inner wall of the bearing is fixedly installed on the top of the surface of the second screw, and the outer ring of the bearing is fixedly installed with the second friction disc. The sleeve is fixedly installed on the top of the second friction disc, and the inner wall of the sleeve is rotatably installed with the second screw. The top of the sleeve is fixedly installed with the connecting plate, and the top of the connecting plate is fixedly installed with the rectangular block. The second friction disc is located on the inner wall of the rectangular block. In this scheme, the cooperation of the second friction disc, sleeve, bearing, and connecting plate enables the rectangular block to have a rotation function, thereby allowing the angle of the mold to be adjusted by rotation during drilling to improve drilling accuracy.

[0011] Preferably, guide blocks are fixedly connected to the top of the base plate near the two sides of the first friction disk. The two sides of the surface of the first friction disk are slidably mounted on the inner wall of the guide blocks. In this scheme, the guide blocks can limit the movement of the first friction disk, so that the first friction disk can only move up and down along the axial direction. At the same time, the first friction disk can always be aligned with the second friction disk, ensuring that it can fit with the second friction disk every time it rises.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The adjustable fixing fixture for drilling molds described in this utility model, through the arrangement of side plates, first screws, clamping blocks, slots, and knobs, enables the side plates, first screws, and clamping blocks to clamp the mold by adjusting the components. At the same time, the individual design of multiple sets of first screws can adapt to different concave depths of the mold, thereby enabling the clamping of different molds. The combination of the slots and knobs allows the user to easily drive the first screws to move to one side. The slots allow the side plates to clamp the first screws, so that the first screws can only move laterally and not rotate.

[0014] 2. The adjustable fixing fixture for drilling molds described in this utility model, through the arrangement of a support platform, a slot, a servo motor, a second screw, and a first friction disc, allows the user to easily and accurately place the mold on the table without deliberate placement. The servo motor, the second screw, and the first friction disc can be controlled by the user to drive the first friction disc to move upward. When the first friction disc rises, it will press against the second friction disc and generate friction with it to fix the second friction disc. Attached Figure Description

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, an adjustable fixing fixture for punching holes in a mold includes a base plate 1; support legs 2 are fixedly installed on both sides of the bottom of the base plate 1, a rectangular block 3 is movably installed on the top of the base plate 1, a clamping mechanism 4 is provided on the top of the rectangular block 3, and an adjusting component 5 is provided on one side of the clamping mechanism 4; a support component 6 is provided on the top of the rectangular block 3, and a fixing mechanism 7 is provided on the bottom of the base plate 1; a rotating mechanism 8 is provided on the inner wall of the rectangular block 3; the clamping mechanism 4 includes a side plate 41, a first screw 42, and a clamping block 43, and the side plate 41 is provided with... Four sets of side plates 41 are fixedly installed on the top of the rectangular block 3. Several sets of first screws 42 are provided, and these sets of first screws 42 are laterally slidably installed on the inner wall of the side plate 41. One end of the first screw 42 is fixedly installed to the clamping block 43. The adjusting assembly 5 includes a slot 51 and a knob 52. The slot 51 is annularly formed on the surface of the first screw 42. Several sets of knobs 52 are provided, and these sets of knobs 52 are laterally rotatable on the side of the side plate 41 away from the clamping block 43. The knobs 52 are threadedly connected to the first screw 42. The support assembly 6... The system includes a support platform 61 and a slot 62. The support platform 61 is fixedly installed on the top of the rectangular block 3. The slot 62 is formed on the surface of the support platform 61. The fixing mechanism 7 includes a servo motor 71, a second screw 72, and a first friction disc 73. The servo motor 71 is fixedly installed on the bottom of the base plate 1. The second screw 72 is fixedly installed on the output end of the servo motor 71 and passes through the base plate 1. The surface of the second screw 72 is threadedly connected to the first friction disc 73. The rotating mechanism 8 includes a second friction disc 81, a sleeve 82, a bearing 83, and a connecting plate 84. The bearing 81... The inner wall of the first friction plate 72 is fixedly installed on the top of the surface of the second screw 72. The outer ring of the bearing 83 is fixedly installed with the second friction disc 81. The sleeve 82 is fixedly installed on the top of the second friction disc 81. The inner wall of the sleeve 82 is rotatably installed with the second screw 72. The top of the sleeve 82 is fixedly installed with the connecting plate 84. The top of the connecting plate 84 is fixedly installed with the rectangular block 3. The second friction disc 81 is located on the inner wall of the rectangular block 3. Guide blocks are fixedly connected to the top of the base plate 1 near the two sides of the first friction disc 73. The two sides of the surface of the first friction disc 73 are slidably installed on the inner wall of the guide blocks.

[0026] like Figures 1 to 5As shown, the side plate 41, the first screw 42, and the first screw 42 working together can clamp the mold by adjusting the drive of the component 5. The individual design of multiple sets of first screws 42 can adapt to different mold depths, thus enabling clamping of different molds. The combination of the slot 51 and the knob 52 allows the user to easily drive the first screw 42 to one side. The slot 51 allows the side plate 41 to clamp the first screw 42, ensuring that the first screw 42 can only move laterally and not rotate. The combination of the support platform 61 and the slot 62 allows the user to accurately place the mold on the platform without deliberate placement. The servo motor 71, the second screw 72, and the first friction... The use of disc 73 allows the user to control the upward movement of the first friction disc 73. When the first friction disc 73 rises, it presses against the second friction disc 81 and generates friction with it to fix the second friction disc 81. The use of the second friction disc 81, sleeve 82, bearing 83 and connecting plate 84 allows the rectangular block 3 to have a rotation function, so that the angle of the mold can be adjusted by rotation during drilling to improve drilling accuracy. The guide block can limit the first friction disc 73, so that the first friction disc 73 can only move up and down along the axial direction. At the same time, it can also keep the first friction disc 73 aligned with the second friction disc 81, ensuring that it fits the second friction disc 81 every time it rises.

[0027] Working principle: During operation, first place the base plate 1 on a flat surface. Then, the user places the mold on top of the support platform 61 and rotates the knob 52. As the knob 52 rotates, it drives the first screw 42 via a threaded connection, moving it towards the mold. As the first screw 42 moves, the clamping blocks 43 press against the mold. With multiple clamping blocks 43 clamping simultaneously, the mold is stably held. The flexible adjustment of the multiple clamping blocks 43 allows for adaptation to molds of different shapes, ensuring the fixture is compatible with various mold types. Furthermore, when adjusting the angle during drilling, the user can activate the servo motor 71. The second screw 72 is driven to rotate, and when the second screw 72 rotates, it drives the first friction disk 73 to move downward, so that the first friction disk 73 is no longer in contact with the second friction disk 81. At this time, since the second friction disk 81 is no longer bound by the sleeve 82 and the connecting plate 84, it can rotate freely. Then, the user can rotate the rectangular block 3 to adjust the angle of the mold to achieve flexible adjustment at multiple angles. After the angle adjustment is completed, the user needs to start the servo motor 71 to drive the first friction disk 73 to reset, so that the first friction disk 73 is in contact with the second friction disk 81 and friction is generated to fix the second friction disk 81 and prevent it from continuing to rotate.
