Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, and more specifically to an adjustable processing fixture for high-precision plastic molds. Background Art

[0002] Jig design is also called fixture and inspection design. Jigs are divided into two types: tooling jigs and inspection jigs. The former is a kind of jig designed for machining, welding, assembly and other processes to facilitate machining and meet the needs of precision; the latter is used for testing. In the process of making high-precision plastic molds, machining jigs are needed to position and clamp them.

[0003] The shortcomings of the existing technology: the existing processing jig cannot adjust its angle well during use, cannot meet the processing requirements of the mold, and when clamping the mold, it is generally placed on a plane first, and then the clamp is controlled to clamp it. Since the mold cannot be accurately placed in the middle of the clamp, the mold will move due to the clamping of the clamp, causing the bottom of the mold to rub against the plane, making the bottom of the mold prone to wear. Utility Model Content

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model is convenient for adjusting the angle of the processing table by providing an angle adjustment device, an angle disk and a processing table. The rotating drum and the rotating column can rotate relatively, and the rotating column is fixed on the bottom box so that the processing table can rotate. The connecting block on the right side of the push rod is fixed on the bottom of the processing table. The stud is rotated by starting the motor. The interior of the slider is provided with a notch matched with the stud. The slider can move back and forth by rotating the stud in different directions. When moving, it can drive the push rod to rotate on the outside of the connecting column, thereby lifting the processing table to rotate it with the rotating column as the axis, thereby enabling its angle to be changed. When the processing table rotates, it will drive the pointer to rotate. The angle of rotation can be known by the scale on the angle disk where the pointer stays, which is convenient for mold processing.

[0013] 2. The utility model is provided with a clamping plate and a placing column, which is conducive to ensuring that the bottom of the mold will not be worn when it is fixed. The socket inside the clamping plate corresponds to the placing column on the other clamping plate, so that the placing column on one clamping plate can be inserted into the socket on the other clamping plate, which is convenient for fixing smaller molds. The mold is placed on the placing column, and two opposite threads are provided on the outer side of the rotating shaft, and the shaft groove is adapted to the threads. By rotating the rotating shaft in different directions, the two clamping plates can move toward the middle and both sides at the same time, so as to clamp the mold, and can fix molds of different sizes. When fixing, since the mold is not placed in the center position, the clamping plate will drive the mold to move on the placing column, and the movable cylinder can rotate on the outer side of the fixed shaft, so that the mold can be moved more easily, and the bottom will not be worn due to the movement, thereby ensuring the integrity of the mold during processing.

Another connecting block 606 is fixedly connected to the side, and the rotating drum 304 and the rotating column 305 can rotate relative to each other. The rotating column 305 is fixed on the bottom box 1, so that the processing table 3 can rotate. The connecting block 606 on the right side of the push rod 604 is fixed to the bottom of the processing table 3. The stud 602 is rotated by starting the motor 601. The interior of the slider 605 is provided with a groove adapted to the stud 602. The slider 605 can move back and forth by rotating the stud 602 in different directions. When moving, it can drive the push rod 604 to rotate on the outside of the connecting column 607, thereby lifting the processing table 3 so that it rotates with the rotating column 305 as the axis, thereby changing its angle. When the processing table 3 rotates, it will drive the pointer 306 to rotate. The angle of rotation can be known by the scale 202 on the angle disk 2 where the pointer 306 stays, which is convenient for the processing of the mold.

[0022] Furthermore, the bottom box 1 includes a box body 101 , and a limiting groove 102 is provided on the inner side of the box body 101 . The limiting groove 102 is used to limit the slider 605 to prevent it from rotating.

[0023] Furthermore, the angle disc 2 includes a disc body 201 , and a scale 202 is provided on the front side of the disc body 201 . The adjusted angle can be known by the scale 202 pointed to by the pointer 306 .

[0024] Furthermore, the processing table 3 includes a table body 301, which is movably connected to a rotating shaft 302 inside the table body 301, and a turntable 303 is fixedly connected to both sides of the rotating shaft 302. A limiting column 307 is fixedly connected to the inner side of the table body 301, and a pointer 306 is fixedly connected to the front and rear sides of the table body 301. A rotating cylinder 304 is fixedly connected to the bottom of the table body 301, and a rotating column 305 is movably connected to the inside of the rotating cylinder 304.

When the clamp 4 clamps the mold placed on the placement column 5, since the mold is not placed in the center position between the two clamps 4, it will drive the mold to move on the placement column 5, and the movable cylinder 502 can rotate on the outer side of the fixed shaft 503, so that the mold can be moved more easily and the bottom will not be worn due to the movement, thereby ensuring the integrity of the mold during processing.

[0027] The working principle of the utility model is as follows: when in use, the mold is first fixed, and the clamping plate 4 can move back and forth by rotating the rotating shaft 302 in different directions, so that it can clamp the mold and fix it. When the clamping plate 4 clamps the mold placed on the placement column 5, since the mold is not placed in the center position between the two clamping plates 4, as the clamping plate 4 continues to move, it will drive the mold to move on the placement column 5, and the movable cylinder 502 can rotate on the outside of the fixed shaft 503, so that the mold can be moved more easily, and its bottom will not appear due to the movement. In order to prevent the wear and tear and ensure the integrity of the mold during processing, the motor 601 is started to rotate the stud 602, and the slider 605 can move back and forth by rotating in different directions.
