Abstract
Description
Technical Field
[0001] This utility model relates to the field of sign forming technology, and in particular to a sign stamping forming machine. Background Technology
[0002] Signage forming refers to the manufacturing process of processing metal sheets, plastic sheets, or other materials into signs with specific shapes, text, patterns, or functions through mechanical processing. A sign stamping machine is a specialized piece of machinery primarily used to process metal or plastic sheets into various signs through a stamping process.
[0003] To address this, patent CN218574723U discloses a sign stamping device, belonging to the field of sign processing equipment. The device includes a stamping equipment body with an upper positioning mold and a lower positioning mold that cooperate with each other. The upper positioning mold has several positioning protrusions, and the corresponding lower positioning mold has positioning holes that match the positioning protrusions. A limiting protrusion is fixed on the base surface of the lower positioning mold, and a limiting groove that matches the limiting protrusion is opened on the corresponding upper positioning mold. The equipment body also has several guide rods for guiding the upper and lower positioning molds, and corresponding openings that match the guide rods are opened on the upper and lower positioning molds. The limiting protrusions limit the material to be processed, while the positioning protrusions and positioning holes punch and position the material. This combination of limiting and positioning prevents material displacement during the stamping process, resulting in a better sign forming effect.
[0004] The aforementioned sign stamping device makes it inconvenient to replace the mold during use. Consequently, when different sizes of signs need to be processed, the entire positioning mold needs to be replaced, making the operation relatively complicated and reducing production efficiency. Utility Model Content
[0005] The purpose of this utility model is to provide a sign stamping machine to solve the problem that existing sign stamping devices are not convenient for changing molds.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sign stamping machine, including a base;
[0007] Each of the following structures has a support rod fixed at the top edge of the base, a top plate fixed at the top of the support rod, and a fixing structure installed at the top of the base. The fixing structure includes a worktable installed at the top of the base, a support rod fixed at the bottom edge of the worktable, a first spring installed on the outer side of the support rod, an internal groove provided at the inner edge of the base, a limit block fixed at the bottom end of the first spring inside the internal groove, an internal cavity provided inside the worktable, a bidirectional lead screw installed inside the internal cavity, guide rods fixed on both sides inside the internal cavity, a moving block installed on the outer side of the bidirectional lead screw and guide rods, and a first sliding groove provided on both sides of the top of the worktable. A first clamping plate is fixed at the top of the moving block inside the first sliding groove.
[0008] A mold base is placed on the top of the workbench, and an installation structure is installed on the top of the top plate.
[0009] Preferably, movable grooves are provided on both sides of the inside of the worktable, a fixed rod is fixed inside the movable groove, a second spring is installed on the outside of the fixed rod, a slider is provided at one end of the second spring outside the fixed rod, a second sliding groove is provided on the other two sides of the top of the worktable, a second clamping plate is fixed at the top of the slider inside the second sliding groove, and a rotating block is fixed at one end of the bidirectional lead screw on one side of the worktable.
[0010] Preferably, the support rods are evenly spaced at the bottom of the worktable, the support rods and the base are slidably connected by built-in grooves, and the worktable and the base are telescopically connected by a first spring.
[0011] With the above structure, the support rods are evenly distributed at the bottom of the worktable during use, providing stable support for the worktable and ensuring that the worktable remains balanced when placing the mold base and performing stamping operations. This avoids tilting or shaking due to uneven support, and the first spring can absorb and buffer this external force, reducing the direct impact of external forces on the overall structure of the equipment.
[0012] Preferably, the movable blocks are symmetrically distributed on the outside of the bidirectional lead screw inside the built-in cavity, the movable blocks are threadedly connected to the bidirectional lead screw, the movable blocks are slidably connected to the guide rod, and the first slide grooves are symmetrically distributed on both sides of the top of the worktable.
[0013] With the above structure, the guide rod provides guidance for the movement of the moving block during use, thereby limiting the movement trajectory of the moving block and preventing the moving block from deviating or shaking during movement. This ensures the accuracy and stability of the movement of the first clamping plate, and thus ensures the accurate clamping position of the mold base.
[0014] Preferably, the movable grooves are symmetrically distributed inside the worktable, the slider and the fixed rod form a telescopic structure through a second spring, and the second sliding grooves are symmetrically distributed on the other two sides of the top of the worktable.
[0015] With the above structure, during use, the second clamping plates on both sides can simultaneously apply longitudinal clamping force to the mold base under the action of the second spring, and cooperate with the first clamping plate for lateral clamping to form double clamping, ensuring that the mold base is firmly fixed.
[0016] Preferably, the mounting structure includes a hydraulic push rod mounted on the top of the top plate, a sliding plate mounted on the output end of the hydraulic push rod at the bottom of the top plate, a sliding hole provided on the outer side of the internal support rod of the sliding plate, a third spring mounted on the outer side of the bottom support rod of the sliding plate, a pressure plate mounted on the bottom of the sliding plate, a T-slot provided on the bottom of the sliding plate, a T-block fixed at the top of the pressure plate inside the T-slot, movable rods mounted inside the sliding plates on both sides of the T-block, a guide block fixed at one end of the movable rod, a fourth spring mounted on the outer side of the movable rod, a reset plate mounted on one end of the fourth spring outside the movable rod, a positioning pin fixed on one side of the reset plate, and positioning holes provided on both sides of the T-block outside the positioning pin.
[0017] Preferably, the sliding plate and the support rod are slidably connected through a sliding hole, the sliding plate and the support rod are telescopically connected through a third spring, and the T-block and the sliding plate are slidably connected through a T-slot.
[0018] The above structure restricts the movement trajectory of the sliding plate through the sliding hole during use, allowing it to move only along the axial direction of the support rod. This prevents the sliding plate from shifting or wobbling during movement, ensuring the accuracy of the sliding plate driving the pressure plate. As a result, the pressure plate can accurately cooperate with the mold base to perform stamping operations, thus improving the stamping accuracy of the signboard.
[0019] Preferably, spring grooves are provided on both sides of the sliding plate, the movable rod and the sliding plate form a telescopic structure through a fourth spring, the positioning pin is tapered, the positioning pin and the T-block form a locking structure through positioning holes, and the positioning holes are symmetrically distributed at the middle position on both sides of the T-block.
[0020] With the above structure, the positioning pin is set in a conical shape and forms a locking structure with the positioning holes symmetrically distributed in the middle of both sides of the T-block during use, thereby locking the T-block and ensuring that the pressure plate is accurately positioned on the sliding plate, avoiding deviation in the forming of the sign due to pressure plate offset during stamping.
[0021] The advantages of the sign stamping machine provided by this utility model are as follows:
[0022] By incorporating a fixed structure, the rotating block drives a bidirectional lead screw to rotate, which in turn causes a moving block to move the first clamping plate within the first slide groove, achieving lateral clamping of the mold base. Simultaneously, it pushes the second clamping plate, which, under the action of a second spring, clamps the mold base longitudinally. This dual clamping method, combining lateral and longitudinal clamping, securely fixes the mold base and can be adjusted according to the size of the mold base, facilitating the replacement of mold bases of different specifications and improving the equipment's adaptability to various mold bases.
[0023] With an installed mounting structure, the T-block is slid into the T-slot. When the T-block reaches the middle position, the positioning pin, under the action of the fourth spring, inserts into the positioning hole on the T-block, achieving precise positioning of the T-block and ensuring the accurate positioning of the pressure plate. Precise positioning allows the pressure plate to be accurately pressed into the mold base for stamping the sign, improving the forming quality and consistency of the sign, reducing the scrap rate, and facilitating the replacement of different types of pressure plates, thus enhancing practicality.

Detailed Implementation
[0030] 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.
[0031] Please see Figure 1-5 The present invention provides a sign stamping machine, including a base 1.
[0032] Reference Figures 1-4 As shown, support rods 2 are fixed at the top edge of the base 1, and top plates 3 are fixed at the top of the support rods 2. A fixing structure 4 is installed at the top of the base 1. The fixing structure 4 includes a worktable 401 installed at the top of the base 1. Support rods 402 are fixed at the bottom edge of the worktable 401. A first spring 403 is installed on the outside of the support rods 402. An internal groove 404 is provided at the inner edge of the base 1. A limit block 405 is fixed at the bottom of the first spring 403 inside the internal groove 404. An internal groove 405 is provided inside the worktable 401. A cavity 406 is provided, and a bidirectional lead screw 407 is installed inside the cavity 406. Guide rods 408 are fixed on both sides inside the cavity 406. Movable blocks 409 are installed on the outer sides of the bidirectional lead screw 407 and guide rods 408. First slide grooves 410 are provided on both sides of the top of the worktable 401. First clamping plates 411 are fixed to the top of the movable blocks 409 inside the first slide grooves 410. Movable grooves 412 are provided on both sides inside the worktable 401. Fixed rods 413 are fixed inside the movable grooves 412. A clamping plate 411 is installed on the outer side of the fixed rods 413. The second spring 414 is located on the outer side of the fixing rod 413. A slider 415 is provided at one end of the second spring 414. Second grooves 416 are provided on both sides of the top of the worktable 401. A second clamping plate 417 is fixed to the top of the slider 415 inside the second groove 416. A rotating block 418 is fixed to one end of a bidirectional lead screw 407 on one side of the worktable 401. Support rods 402 are evenly distributed at the bottom of the worktable 401. The support rods 402 and the base 1 are slidably connected via an internal groove 404. The worktable 401 and the base 1 are connected by a first spring 414. 03 forms a telescopic structure. The moving blocks 409 are symmetrically distributed on the outside of the bidirectional lead screw 407 inside the built-in cavity 406. The moving blocks 409 are threadedly connected to the bidirectional lead screw 407. The moving blocks 409 are slidably connected to the guide rod 408.

The slider 415 and the fixed rod 413 form a telescopic structure through the second spring 414. The second slide groove 416 is symmetrically distributed on the other two sides of the top of the worktable 401.
[0033] The mold base 5 is placed on the worktable 401. Rotating the rotating block 418 drives the bidirectional lead screw 407 to rotate, causing the moving block 409 to move along the guide rod 408 under the drive of the bidirectional lead screw 407. This, in turn, moves the first clamping plate 411 within the first slide groove 410, allowing the first clamping plate 411 to laterally clamp the mold base 5. Simultaneously, it pushes the second clamping plate 417, causing the slider 415 to slide within the movable groove 412. This compresses the second spring 414, and after release, the second spring 414 returns to its original position, fixing the second clamping plate 417 within the second slide groove 416. This achieves longitudinal clamping of the mold base 5, thus completing the installation and fixing of the mold base 5, facilitating the replacement of mold bases 5 of different sizes. Furthermore, when the mold base 5 is stamped, the worktable 401 is subjected to external force, causing the support rod 402 to slide within the internal groove 404, thereby allowing the first spring 403 to act as a buffer.
[0034] Reference Figures 2-5 As shown, a mold base 5 is placed at the top of the workbench 401, and an installation structure 6 is installed at the top of the top plate 3. The installation structure 6 includes a hydraulic push rod 601 installed at the top of the top plate 3. A sliding plate 602 is installed at the output end of the hydraulic push rod 601 at the bottom of the top plate 3. A sliding hole 603 is provided on the outer side of the internal support rod 2 of the sliding plate 602. A third spring 604 is installed on the outer side of the internal support rod 2 of the sliding plate 602. A pressure plate 605 is installed at the bottom of the sliding plate 602. A T-slot 606 is provided at the bottom of the sliding plate 602. A T-block 607 is fixed at the top of the pressure plate 605 inside the T-slot 606. Movable rods 608 are installed inside the sliding plates 602 on both sides of the T-block 607. A guide block 609 is fixed at one end of the movable rod 608. A fourth spring 610 is installed on the outer side of the movable rod 608. A reset plate 611 is installed at one end of the fourth spring 610 on the outer side of 608. A positioning pin 612 is fixed on one side of the reset plate 611. Positioning holes 613 are provided on both sides of the T-shaped block 607 on the outer side of the positioning pin 612. The sliding plate 602 and the support rod 2 are slidably connected through the sliding hole 603. The sliding plate 602 and the support rod 2 are telescopically connected through the third spring 604. The T-shaped block 607 and the sliding plate 602 are slidably connected through the T-shaped groove 606. Spring grooves are provided on both sides inside the sliding plate 602.

The positioning holes 613 are symmetrically distributed at the middle position on both sides of the T-shaped block 607.
[0035] By activating the hydraulic push rod 601, the sliding plate 602 is pushed down along the support rod 2. The sliding plate 602 and the support rod 2 are slidably connected through the sliding hole 603. At the same time, the third spring 604 is sleeved on the outside of the support rod 2 to provide buffer and restoring force for the sliding plate 602, ensuring the stability of the sliding plate 602 as it moves down. By sliding the T-block 607 into the interior of the T-slot 606, when the T-block 607 slides to the middle position, the positioning pin 612 is inserted into the positioning hole 613 on the T-block 607 under the action of the fourth spring 610, so as to achieve precise positioning of the T-block 607 and ensure the accurate position of the pressure plate 605. Then, the sliding plate 602 drives the pressure plate 605 to press down, so that the pressure plate 605 is pressed into the mold base 5 to stamp and form the sign.
