Description

Technical Field

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

[0002] Currently, molds are an important component of injection molding machines. Different injection molds are often required in the processing of different plastic parts. During the production process, injection molds are often machined using CNC machining centers to ensure they meet production requirements.

[0003] Traditional injection mold processing fixtures are typically fixed structures, which present several problems. First, these fixed fixtures cannot rotate. During mold processing, it is often necessary to process the mold from different angles. Because traditional fixtures cannot rotate, different angles can only be achieved by readjusting the entire processing equipment or manually adjusting the mold's position on the fixture. This process is extremely cumbersome and time-consuming. Each adjustment requires significant time for recalibration, severely impacting processing efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fixture assembly for injection mold processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixture assembly for injection mold processing, comprising a fixture table and a fixture disk, wherein the fixture disk is rotatably connected to the top of the fixture table, an indexing mechanism is provided at the bottom of the fixture disk, a locking mechanism is provided at the bottom of the fixture disk, a positioning clamping mechanism is fixedly connected to the top of the fixture disk, an initial positioning mechanism is provided at the top of the fixture disk, and a positioning groove is provided at the top of the fixture disk.

[0006] As a further technical solution of this utility model, the clamping disk includes a clamping disk body, an indexing disk is fixedly connected to the bottom of the clamping disk body, a plurality of indexing grooves are opened on the side surface of the indexing disk, a locking hole is opened at the bottom of the indexing disk, a rotating shaft is fixedly connected to the bottom of the indexing disk, and the clamping disk is rotatably connected to the clamping table through the rotating shaft.

[0007] As a further technical solution of this utility model, the indexing mechanism includes an indexing motor, a drive rod is fixedly connected to the drive end of the indexing motor, a rotating rod is fixedly connected to the top of the drive rod, an indexing rod is fixedly connected to the rotating rod, and an unlocking arc plate is fixedly connected to the rotating rod at the bottom of the indexing rod.

[0008] As a further technical solution of this utility model, the locking mechanism includes a locking chamber, a locking slide plate is slidably connected inside the locking chamber, two locking springs are provided between the inner wall of the locking chamber and the bottom of the locking slide plate, an unlocking rod is fixedly connected to the top of the locking slide plate, and a locking rod is fixedly connected to the top of the locking slide plate.

[0009] As a further technical solution of this utility model, the positioning and clamping mechanism includes a motor frame, a clamping motor is mounted on the top of the motor frame, a bidirectional threaded rod is fixedly connected to the drive end of the clamping motor, a clamping rod is threadedly connected to the surface of the bidirectional threaded rod, a positioning slider is fixedly connected to the bottom of the clamping rod, and a support sleeve is rotatably connected to the middle of the surface of the bidirectional threaded rod.

[0010] As a further technical solution of this utility model, the motor frame is fixedly connected to the side of the clamping disk, the clamping rod is slidably connected to the top of the clamping disk, the support sleeve is fixedly connected to the top of the clamping disk, and the positioning slider is adapted to the positioning groove.

[0011] As a further technical solution of this utility model, the initial positioning mechanism includes a number of symmetrically opened initial positioning holes and two initial positioning rods. The initial positioning holes are opened on the top of the fixture plate, and a fixed threaded rod is fixedly connected to the bottom of the initial positioning rod. The fixed threaded rod is threadedly connected to the initial positioning hole.

[0012] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0013] 1. This utility model, through the setting of a clamping plate, indexing mechanism, and locking mechanism that cooperate with each other, allows the indexing motor to be activated when the clamping needs to be rotated due to mold processing requirements. The indexing motor drives the drive rod to rotate, which in turn causes the rotating rod to rotate around the drive rod. The indexing rod extends into the indexing groove, driving the indexing plate to rotate, which in turn causes the clamping plate to rotate. At the same time as the indexing rod extends into the indexing groove, the unlocking arc plate passes over the unlocking rod. Due to the rounded corner design, the locking spring at the bottom of the unlocking rod is compressed, the locking slide moves down, and the locking rod moves down simultaneously to disengage from the locking hole, ensuring that the indexing plate can rotate. After the indexing plate completes its rotation, the unlocking arc plate leaves, the locking spring returns to its original position, and the locking rod extends back into the corresponding locking hole to complete the locking, preventing the indexing plate from rotating. The clamping has a rotation function, which can easily change the processing angle of the mold without readjusting the entire processing equipment. Combined with the indexing function, the clamping can be precisely rotated to a specific angle to meet the needs of multi-faceted or multi-angle processing of complex molds.

[0014] 2. This utility model features a positioning and clamping mechanism. The initial positioning rod is fixed in different initial positioning holes according to the mold model. One side of the mold is pressed tightly against the initial positioning rod. The clamping motor is started, driving the bidirectional threaded rod to rotate. By opening opposing threaded grooves, the clamping rod moves synchronously by the same distance, thus fixing the mold in the middle position. This completes the clamping and positioning of the mold, enabling the mold to be quickly and accurately positioned on the fixture plate. This not only saves positioning time and improves processing efficiency but also ensures the accuracy of the mold's position during processing. Attached Figure Description

[0021] 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.

[0022] like Figure 1-5As shown, this utility model provides a technical solution: a fixture assembly for injection mold processing, including a fixture table 1 and a fixture disk 2. The fixture disk 2 is rotatably connected to the top of the fixture table 1. An indexing mechanism 3 is provided at the bottom of the fixture disk 2. A locking mechanism 4 is provided at the bottom of the fixture disk 2. A positioning clamping mechanism 5 is fixedly connected to the top of the fixture disk 2. An initial positioning mechanism 6 is provided at the top of the fixture disk 2. A positioning groove 7 is opened on the top of the fixture disk 2.

[0023] The clamping disc 2 includes a clamping disc body 201, with an indexing disc 202 fixedly connected to the bottom of the clamping disc body 201. The indexing disc 202 has several indexing slots 203 on its side surface and a locking hole 204 at its bottom. A rotating shaft 205 is fixedly connected to the bottom of the indexing disc 202, and the clamping disc 2 is rotatably connected to the clamping table 1 via the rotating shaft 205. The indexing mechanism 3 includes an indexing motor 301, with a drive rod 302 fixedly connected to the drive end of the indexing motor 301. The top of the drive rod 302 is fixedly connected to... A rotating rod 303 is connected to the rotating rod 303, and an indexing rod 304 is fixedly connected to the rotating rod 303. An unlocking arc plate 305 is fixedly connected to the rotating rod 303 at the bottom of the indexing rod 304. The locking mechanism 4 includes a locking chamber 401, a locking slide plate 402 is slidably connected inside the locking chamber 401, two locking springs 403 are provided between the inner wall of the locking chamber 401 and the bottom of the locking slide plate 402, an unlocking rod 404 is fixedly connected to the top of the locking slide plate 402, and a locking rod 405 is fixedly connected to the top of the locking slide plate 402.

[0024] By setting up a mutually cooperating clamping plate 2, indexing mechanism 3, and locking mechanism 4, when the clamping needs to be rotated due to mold processing requirements, the indexing motor 301 can be activated. The indexing motor 301 drives the drive rod 302 to rotate, which in turn causes the rotating rod 303 to rotate around the drive rod 302. The indexing rod 304 extends into the indexing groove 203, driving the indexing plate 202 to rotate, which in turn causes the clamping plate 2 to rotate. At the same time as the indexing rod 304 extends into the indexing groove 203, the arc plate 30 is unlocked. 5 passes over the unlocking rod 404. Due to the rounded corner design, the locking spring 403 at the bottom of the unlocking rod 404 is compressed, the locking slide plate 402 moves down, and the locking rod 405 moves down simultaneously to disengage from the locking hole 204, ensuring that the indexing plate 202 can rotate. After the indexing plate 202 completes its rotation, the unlocking arc plate 305 leaves, the locking spring 403 returns to its original position, and the locking rod 405 extends into the corresponding locking hole 204 to complete the locking, preventing the indexing plate 202 from rotating.

[0025] A positioning and clamping mechanism 5 is also provided. According to the mold model, the initial positioning rod 602 is fixed in different initial positioning holes 601. One side of the mold is pressed tightly against the initial positioning rod 602. The clamping motor 502 is started, which drives the bidirectional threaded rod 503 to rotate. By opening opposing threaded grooves, the clamping rod 504 moves synchronously by the same distance, so that the mold is fixed in the middle position, and the clamping and positioning of the mold is completed.

[0026] like Figure 1 , Figure 4 , Figure 5 As shown, the positioning and clamping mechanism 5 includes a motor frame 501, a clamping motor 502 mounted on the top of the motor frame 501, a bidirectional threaded rod 503 fixedly connected to the drive end of the clamping motor 502, a clamping rod 504 threadedly connected to the surface of the bidirectional threaded rod 503, a positioning slider 505 fixedly connected to the bottom of the clamping rod 504, a support sleeve 506 rotatably connected to the middle of the surface of the bidirectional threaded rod 503, the motor frame 501 fixedly connected to the side of the fixture disk 2, the clamping rod 504 slidably connected to the top of the fixture disk 2, the support sleeve 506 fixedly connected to the top of the fixture disk 2, and the positioning slider 505 adapted to the positioning groove 7. The initial positioning mechanism 6 includes several symmetrically opened initial positioning holes 601 and two initial positioning rods 602. The initial positioning holes 601 are opened on the top of the fixture disk 2, and a fixing threaded rod 603 is fixedly connected to the bottom of the initial positioning rod 602. The fixing threaded rod 603 is threadedly connected to the initial positioning hole 601.

[0027] The working principle of this utility model is as follows: By setting up a clamping plate 2, an indexing mechanism 3, and a locking mechanism 4 that cooperate with each other, when the clamping needs to be rotated due to the requirements of mold processing, the indexing motor 301 can be started. The indexing motor 301 drives the drive rod 302 to rotate, which in turn causes the rotating rod 303 to rotate around the drive rod 302. The indexing rod 304 extends into the indexing groove 203 and drives the indexing plate 202 to rotate, which in turn causes the clamping plate 2 to rotate. At the same time as the indexing rod 304 extends into the indexing groove 203, the unlocking arc plate 305 passes over the unlocking rod 404. Due to the rounded corner design, the locking spring 403 at the bottom of the unlocking rod 404 is compressed, the locking slide plate 402 moves down, and the locking rod 405 moves down simultaneously to disengage from the locking hole 204, ensuring that the indexing plate 202 can rotate.

[0028] After the indexing plate 202 completes its rotation, the unlocking arc plate 305 is released, the locking spring 403 returns to its original position, and the locking rod 405 extends into the corresponding locking hole 204 to complete the locking, preventing the indexing plate 202 from rotating. A positioning clamping mechanism 5 is also provided. According to the mold model, the initial fixing rod 602 is fixed in different initial fixing holes 601. One side of the mold is pressed tightly against the initial fixing rod 602, and the clamping motor 502 is started to drive the bidirectional threaded rod 503 to rotate. By opening opposing threaded grooves, the clamping rod 504 moves synchronously by the same distance, so that the mold is fixed in the middle position, completing the clamping and positioning of the mold.
