Description

Technical Field

[0001] This invention relates to the field of mold fixing technology, and in particular to a fixing bracket for hardware molds. Background Technology

[0002] A hardware mold fixing bracket is a device used to fix hardware molds, which can ensure that the mold remains stable during processing and improve processing accuracy and efficiency. However, the fixing bracket has poor applicability when fixing the mold. It cannot be flexibly adjusted according to the positioning needs of the mold. It can only fix and limit the mold in a single way. This means that when fixing and limiting the mold, other limiting and fixing mechanisms need to be installed as needed. Summary of the Invention

[0003] The main objective of this invention is to provide a fixing bracket for hardware molds, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A fixing frame for hardware molds includes a base and clamping plates. The clamping plates are movably mounted on the upper surface of the base near both sides. An adjustment knob is movably mounted on one side surface of the base. A double-ended screw extending into the base is fixedly mounted on the rear surface of the adjustment knob. Rotating blocks are movably mounted on the upper surface of the clamping plates at both ends. A clamping block is movably mounted on one end of each rotating block. Limiting grooves are formed on the upper surface of the base near the front and rear.

[0005] More preferably, a positioning rod is fixedly installed on the upper surfaces of both ends of the clamping plate near the rear. A lifting groove is formed on the upper surface of the clamping plate on one side of the positioning rod. A limiting groove is formed on the upper surface of the clamping plate in front of the positioning rod. A second limiting groove is formed on both sides of the upper surface of the clamping plate in the middle. A moving groove is formed laterally at both ends of the lower part of the front surface of the clamping plate. A double-ended threaded shaft is movably installed inside the clamping plate. The double-ended threaded shaft passes through the moving groove. A rotating head is movably installed on both ends of the clamping plate. The double-ended threaded shaft is fixed to the rotating head. A threaded sleeve block is threadedly fitted on the surface of the double-ended threaded shaft inside the moving groove. A positioning post is fixedly installed on the front surface of the threaded sleeve block. A threaded sliding sleeve is fixedly installed on the lower surface of the clamping plate. A limiting slider is fixedly installed on the lower surface of the clamping plate near both ends.

[0006] In a further preferred embodiment, the threaded sleeve is threaded onto the double-ended screw, and the limiting slider is embedded in the limiting groove.

[0007] More preferably, the rotating block has an embedded groove inside, and the upper and lower surfaces of the embedded groove have sliding grooves. One end of the rotating block has a through hole at the rear. A second positioning rod is fixedly installed on the lower surface of one end of the rotating block in front of the through hole. A guide rod is fixedly installed on the lower surface of the rotating block at the middle. A support block is fixedly installed on the lower surface of the guide rod. The lower end of the guide rod is embedded in the lifting groove. A third limiting groove is opened on the lower surface of the other end of the rotating block.

[0008] More preferably, the lower end of the guide rod is embedded in the lifting groove, a spring is sleeved on the surface of the guide rod located inside the lifting groove, and the second positioning rod is embedded in the first limiting groove.

[0009] More preferably, an embedding plate is fixedly installed on one side of the rear end of the clamping block, and sliders are fixedly installed on the upper and lower rear end surfaces of the embedding plate, and an adjustment groove is opened on the lower surface of the embedding plate near the rear.

[0010] More preferably, the embedding plate is embedded in the embedding groove, the slider is embedded in the sliding groove, and the first positioning rod passes through the through hole and is embedded in the adjustment groove, and the number of adjustment grooves is several.

[0011] Compared with the prior art, the present invention proposes a fixing bracket for hardware molds, which has the following beneficial effects: In this invention, by setting up a clamping plate, a rotating block, and a clamping block to cooperate with each other, the rotating block is pulled up, causing the second positioning rod of the rotating block to retract from the first limiting groove of the clamping plate. At this time, the rotating block can be rotated. After the rotating block rotates 180°, the external force pulling the rotating block up is released. At this time, the rotating block descends under the action of the spring until the second positioning rod of the rotating block is embedded in the second limiting groove. This can limit the rotation block. At this time, since the clamping block on the rotating block rotates to the rear of the clamping plate, the clamping block can be used flexibly. It can be used or not used according to the needs of use. When using the clamping block, the rotating block is pulled up, causing the first positioning rod to retract from the adjustment groove. Then, the clamping block can be pulled to pull the embedded plate out of the embedded groove to the required length. Then, the external force pulling the rotating block up is released. When the rotating block descends under the action of the spring, the first positioning rod will pass through the through hole and be embedded in another adjustment groove. This can limit the moved embedded plate. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0016] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be used in a broad sense. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0017] like Figures 1-5 As shown, a fixing frame for hardware molds includes a base 1 and a clamping plate 4. The clamping plate 4 is movably installed on the upper surface of the base 1 and near both sides. An adjusting knob 2 is movably installed on one side surface of the base 1. A double-headed screw 3 extending into the base 1 is fixedly installed on the rear surface of the adjusting knob 2. Rotating blocks 5 are movably installed on the upper surface of the clamping plate 4 at both ends. A clamping block 6 is movably installed at one end of the rotating block 5. Limiting grooves 7 are formed on the upper surface of the base 1 near the front and rear.

[0018] In a preferred embodiment: a first positioning rod 401 is fixedly installed on the upper surfaces of both ends of the clamping plate 4 near the rear; a lifting groove 402 is formed on the upper surface of the clamping plate 4 on one side of the first positioning rod 401; a first limiting groove 403 is formed on the upper surface of the clamping plate 4 in front of the first positioning rod 401; a second limiting groove 404 is formed on both sides of the upper surface of the clamping plate 4 in the middle; and a moving groove 409 is formed laterally at both lower ends on the front surface of the clamping plate 4. The clamping plate 4 is movably installed inside. There is a double-threaded shaft 405, which passes through the moving groove 409. Rotating heads 406 are movably installed on both ends of the clamping plate 4. The double-threaded shaft 405 is fixed to the rotating heads 406. The surface of the double-threaded shaft 405 located inside the moving groove 409 is threaded with a threaded sleeve block 410. A positioning post 411 is fixedly installed on the front surface of the threaded sleeve block 410. A threaded sliding sleeve 407 is fixedly installed on the lower surface of the clamping plate 4. A limit slider 408 is fixedly installed on the lower surface of the clamping plate 4 near both ends.

[0019] In the above structure, by rotating the rotating head 406, the double-threaded shaft 405 can be rotated, which can adjust the distance between the two positioning pins 411, so that the positioning pins 411 can be adapted to the position of the positioning hole slots on different molds.

[0020] In a preferred embodiment: the threaded sleeve 407 is threaded onto the double-ended screw 3, and the limiting slider 408 is embedded in the limiting groove 7.

[0021] In a preferred embodiment: the rotating block 5 has an embedding groove 501 inside, and the upper and lower surfaces of the embedding groove 501 have sliding grooves 502. One end of the rotating block 5 has a through hole 503 at the rear. A second positioning rod 504 is fixedly installed on the lower surface of one end of the rotating block 5 in front of the through hole 503. A guide rod 505 is fixedly installed on the lower surface of the rotating block 5 at the middle. A support block 506 is fixedly installed on the lower surface of the guide rod 505. The lower end of the guide rod 505 is embedded in the lifting groove 402. A third limiting groove 508 is opened on the lower surface of the other end of the rotating block 5.

[0022] In the above structure, when the rotating block 5 rotates 180°, the second positioning rod 504 of the rotating block 5 will be embedded in the second limiting groove 404, which can limit the rotation of the rotating block 5 and prevent it from rotating unnecessarily during use.

[0023] In a preferred embodiment: the lower end of the guide rod 505 is embedded in the lifting groove 402, and a spring 507 is sleeved on the surface of the guide rod 505 located inside the lifting groove 402. The second positioning rod 504 is embedded in the first limiting groove 403.

[0024] In the above structure, the spring 507 is in an extended state in its natural state, and the elastic coefficient of the spring 507 must ensure that the rotating block 5 will not rise without a certain upward pulling force, so as to ensure the limiting effect of the cooperation between the second positioning rod 504 and the first limiting groove 403 on the rotating block 5.

[0025] In a preferred embodiment: an insert plate 601 is fixedly installed on one side of the rear end of the clamping block 6, and a slider 602 is fixedly installed on the upper and lower rear end surfaces of the insert plate 601. An adjustment groove 603 is provided on the lower surface of the insert plate 601 near the rear.

[0026] In the above structure, when the No. 1 positioning rod 401 is embedded in the adjustment groove 603 at different positions, it can limit the movement of the embedded plate 601.

[0027] In a preferred embodiment: the mounting plate 601 is embedded in the mounting groove 501, the slider 602 is embedded in the sliding groove 502, and the first positioning rod 401 passes through the through hole 503 and is embedded in the adjustment groove 603. The number of adjustment grooves 603 is several.

[0028] In use, by rotating the adjusting knob 2, the double-headed screw 3 rotates, causing the two clamping plates 4 to move closer and further apart until the positioning pin 411 is embedded in the positioning slots on both sides of the mold. This limits the mold's position. By pulling up the rotating block 5, the second positioning rod 504 of the rotating block 5 disengages from the first limiting slot 403 of the clamping plate 4. At this point, the rotating block 5 can be rotated. After the rotating block 5 rotates 180°, the external force pulling up the rotating block 5 is released. The rotating block 5 then descends under the action of the spring 507 until the second positioning rod 504 of the rotating block 5 is embedded in the second limiting slot 404. This allows the rotating block 5 to be positioned. Limiting the position: Since the clamping block 6 on the rotating block 5 rotates to the rear of the clamping plate 4, the clamping block 6 can be used flexibly. It can be used or not used according to the needs of use. When using the clamping block 6, by pulling the rotating block 5 upward, the first positioning rod 401 is disengaged from the adjustment groove 603. Then, the clamping block 6 can be pulled to pull the embedded plate 601 out of the embedded groove 501 to the required length. Then, the external force of pulling the rotating block 5 upward is released. When the rotating block 5 descends under the action of the spring 507, the first positioning rod 401 will pass through the through hole 503 and be embedded in another adjustment groove 603. In this way, the moved embedded plate 601 can be limited.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
