Description

Technical Field

[0001] This utility model relates to the field of mold debugging equipment technology, specifically to a mold trial molding, correction and debugging device. Background Technology

[0002] As mold manufacturing moves towards modularization and refinement, the need for debugging single-module stamping molds (such as moving dies, punches, and other independent modules) is becoming increasingly prominent. Currently, the industry generally relies on direct testing with stamping equipment for debugging single-module stamping molds, which has the following core defects:

[0003] Difficult to observe: The stamping equipment operates at high speeds (usually tens of times per minute), making it difficult to clearly observe details such as whether the moving die is guided smoothly and whether the punch gap is uniform with the naked eye;

[0004] Inefficiency: The debugging process requires frequent start-up and shutdown of the stamping equipment, resulting in prolonged equipment downtime and severely impacting the overall efficiency of the production line;

[0005] High cost: Debugging requires the use of the entire frame profile for verification. If a single module fails to debug, the entire profile is scrapped, resulting in serious waste of materials.

[0006] Therefore, there is an urgent need in this field for a mold trial calibration and debugging device that can operate independently, adapt to modular single molds, simulate actions at low speeds, and reduce debugging costs, in order to break through the existing technical bottlenecks. Summary of the Invention

[0007] This utility model aims to solve one of the technical problems existing in the prior art.

[0008] This application provides a mold trial molding calibration and debugging device, including a stamping module. The stamping module includes a moving mold, a fixed mold, a punch, a mounting plate and a guide rod. It also includes a frame, a back plate, a lifting plate and a transmission assembly. The lifting plate is connected to an external actuator. The back plate and the moving mold are detachably connected through a connector. The transmission assembly is used to convert the vertical linear lifting motion of the lifting plate into the horizontal linear motion of the back plate.

[0009] The transmission assembly includes a rear plate, a transmission block, an actuator block, and a self-resetting connector. The self-resetting connector slides horizontally through the frame, with its two ends fixed to the back plate and the rear plate, respectively. The transmission block and the actuator block are fixed to the lifting plate and the rear plate, respectively, with their adjacent end faces inclined and fitted together.

[0010] The transmission assembly also includes a guide bar and a guide groove. The guide bar is fixed on the frame, and the guide groove is opened on the bottom surface of the transmission block and slides with the guide bar.

[0011] The self-resetting connector includes a slide rod and a reset spring. The slide rod slides through the frame, and the spring is sleeved on the outside. The two ends of the spring abut against the frame and the back plate, respectively.

[0012] It also includes a limiting component, which is installed on the frame and is used to limit the displacement of the back plate away from the lifting plate when the lifting plate rises in a preset vertical direction and the return spring pushes the back plate away from the lifting plate in a preset horizontal direction, so as to limit the maximum distance travel of the back plate.

[0013] The limiting component includes a limiting rod that slides through the frame, with one end fixed to the back plate and the other end fixed to a blocking block.

[0014] The top of the frame is fitted with a limit bolt located on the lifting path of the lifting plate through a screw hole, and a lock nut is installed on the limit bolt.

[0015] The lifting platform is floatingly installed on the top of the frame via multiple uprights. Each upright is fitted with a lifting spring, and the bottom and top of each spring abut against the bottom surface of the lifting platform and the top surface of the frame, respectively.

[0016] The connector includes a connecting groove, a connecting shaft, and a connecting plate. The connecting groove is opened on the top surface of the back plate. The lower part of the connecting shaft is slidably installed in the connecting groove, and the upper part is inserted into the connecting plate. The other end of the connecting plate is fixed to the moving mold by fasteners. The lower cross-sections of the connecting groove and the connecting shaft are both larger at the bottom and smaller at the top.

[0017] The two ends of the transmission component are respectively inserted into the two ends of the connecting slot.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. Independent debugging: The device is equipped with an independent external actuator (such as a servo motor, cylinder or hydraulic cylinder), which does not rely on the power system of the stamping equipment. The debugging process is completely decoupled from the stamping production line, and can be started and debugged at any time, avoiding the efficiency loss of "equipment shutdown for debugging".

[0020] 2. Observation accuracy: The transmission component converts the vertical movement of the lifting plate into the low / high speed horizontal movement of the moving mold. The guide bar / slot, limit component, lifting spring and other structures ensure smooth movement without vibration. When moving at low speed, the operator can clearly observe the operating status of the moving mold guide mechanism (such as slider jamming, abnormal gap) with the naked eye. After debugging, switch to high speed to observe the practical effect. The mold assembly accuracy is significantly optimized.

[0021] 3. Cost control: The modular quick-connect structure supports independent assembly and disassembly of single-module molds; debugging only requires the scrap material of the first section of the frame profile, instead of the whole profile. The profile loss for single-module debugging is reduced from "scrapping the whole profile" to "reusing the scrap material of the first section", reducing costs by more than 85%.

Detailed Implementation

[0028] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0029] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0030] The mold trial molding, calibration and debugging device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0031] Example 1:

[0032] This application provides a mold trial calibration and debugging device, including a stamping module 1. The stamping module 1 includes a moving mold 101, a fixed mold 102, a punch 103, a mounting plate 104, and a guide rod 105. It also includes a frame 2, a back plate 3, a lifting plate 4, and a transmission assembly 5. The lifting plate 4 is connected to an external actuator. The back plate 3 is detachably connected to the moving mold 101 through a connector 6. The transmission assembly 5 is used to convert the vertical linear lifting motion of the lifting plate 4 into the horizontal linear motion of the back plate 3.

[0033] like Figures 1 to 4 As shown, due to the above structure, when debugging a modular single mold, the moving mold 101 is detachably installed on the back plate 3 via the connector 6. The fixed mold 102, punch 103 and other components are correspondingly adapted and set. The external actuator (such as a lifting mechanism driven by a servo motor, a cylinder or a hydraulic cylinder, etc.) abuts against the top surface of the lifting plate 4, driving the lifting plate 4 to move slowly and linearly in the vertical direction. The transmission component 5 converts this vertical linear motion into the horizontal linear motion of the back plate 3, thereby driving the moving mold 101 to perform a simulated stamping action in the horizontal direction relative to the fixed mold 102 and the punch 103.

[0034] Because this device can independently control the debugging speed (far lower than the actual stamping equipment's operating speed), operators can clearly observe whether the guiding of the moving die 101 is smooth and whether the gap of the punch 103 is uniform. This avoids the problem of difficulty in observing details due to the equipment's excessively fast operation when debugging directly on the stamping equipment, as well as the equipment stopping during the debugging process, which affects production efficiency. After debugging is completed, the high speed is switched to observe whether the guiding of the moving die 101 is smooth and whether the gap of the punch 103 is uniform under actual conditions.

[0035] Example 2:

[0036] The difference from Embodiment 1 is that, in this embodiment, in addition to the structural features of the aforementioned embodiments, the transmission assembly 5 includes a rear plate 51, a transmission block 52, an actuating block 53, and a self-resetting connector. The self-resetting connector is horizontally slidably mounted on the frame 2, with its two ends fixed to the back plate 3 and the rear plate 51, respectively. The transmission block 52 and the actuating block 53 are fixed on the lifting plate 4 and the rear plate 51, respectively, with adjacent end faces inclined and fitted together.

[0037] In this embodiment of the application, the transmission assembly 5 further includes a guide bar 55 and a guide groove 56. The guide bar 55 is fixed on the frame 2, and the guide groove 56 is formed on the bottom surface of the transmission block 52 and slides in cooperation with the guide bar 55.

[0038] like Figures 1 to 4As shown, due to the above structure, during the lifting stage: when the lifting plate 4 descends vertically, the actuating block 53 fixed to the lifting plate 4 pushes the transmission block 52 through the inclined and fitting end face. The guide groove 56 on the bottom surface of the transmission block 52 slides and engages with the guide strip 55 on the frame 2 to ensure that the transmission block 52 moves accurately along the preset horizontal direction, thereby driving the rear plate 51 to move synchronously. The self-resetting connector slides horizontally with the back plate 3 to store reset potential energy (such as elastic deformation potential energy).

[0039] Reset phase: When the lifting plate 4 rises vertically, the thrust of the actuator block 53 and the transmission block 52 is released, the self-reset connector releases potential energy, and drives the back plate 3 to move horizontally in the opposite direction to reset.

[0040] The frame 2 is in the shape of an inverted T, and the transmission assembly 5 is mounted on its vertical surface.

[0041] Example 3:

[0042] The difference from Embodiment 2 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the self-resetting connector includes a slide rod 54 and a reset spring. The slide rod 54 slides through the frame 2, and the reset spring is sleeved on the outside. The two ends of the spring abut against the frame 2 and the back plate 3, respectively.

[0043] In this embodiment of the application, a limiting member 7 is also included. The limiting member 7 is installed on the frame 2 and is used to limit the displacement of the back plate 3 away from the lifting plate 4 when the lifting plate 4 rises in a preset vertical direction and the reset spring pushes the back plate 3 away from the lifting plate 4 in a preset horizontal direction, so as to limit the maximum distance travel of the back plate 3.

[0044] like Figures 1 to 4 As shown, due to the above structure, during the movement phase: when the lifting plate 4 descends vertically, the actuator block 53 pushes the transmission block 52, and the transmission block 52 drives the rear plate 51 and the slide rod 54, so that the back plate 3 overcomes the elastic force of the return spring (not shown in the figure) (the return spring is compressed and stores the return potential energy) and moves horizontally towards the lifting plate 4.

[0045] Reset phase: When the lifting plate 4 rises vertically, the thrust of the actuator block 53 and the transmission block 52 disappears, the reset spring releases its elastic force, and pushes the back plate 3 to move horizontally in the opposite direction to reset.

[0046] Limiting constraints: The limiting component 7 on the frame 2 restricts the maximum displacement of the self-resetting connector as it moves away from the lifting plate 4, ensuring that the horizontal movement range of the moving mold 101 is stable and controllable.

[0047] Example 4:

[0048] The difference from Embodiment 3 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the limiting member 7 includes a limiting rod 71, which slides through the frame 2, with one end fixedly connected to the back plate 3 and the other end fixedly provided with a blocking block 72.

[0049] like Figure 2 As shown, due to the above structure, when the lifting plate 4 rises, the return spring pushes the back plate 3 to move horizontally away from the lifting plate 4, causing the limit rod 71 to slide synchronously until the blocking block 72 at the end of the limit rod 71 abuts against the outer wall of the frame 2, precisely limiting the maximum horizontal stroke of the back plate 3. The limit rod 71 has threads on its surface and is connected to the back plate 3 through a screw hole. The maximum stroke end position of the back plate 3 can be adjusted in real time for different stamping modules 1, so that the opening of the moving mold 101 during the debugging process of the single mold 1 is as consistent as possible with the state during actual use.

[0050] Example 5:

[0051] The difference from Embodiment 3 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the limiting member 7 includes a limiting block 73, which is fixed to the rear side of the top surface of the frame 2 of the device.

[0052] like Figure 2 As shown, due to the above structure, when the lifting plate 4 rises, the return spring (not shown in the figure) drives the back plate 3 to move horizontally away from the lifting plate 4 until the front wall of the rear plate 51 abuts against the limiting block 73 on the rear side of the top surface of the frame 2, limiting the maximum distance travel of the back plate 3; when the lifting plate 4 falls, the return spring is compressed and the limiting block 73 has a simple and reliable structure, effectively constraining the movement range of the back plate 3, ensuring the stability of the movement amplitude of the moving mold 101 during debugging, realizing low-speed, observable simulated stamping action, and switching to high-speed action after debugging to observe the actual effect.

[0053] Example 6:

[0054] The difference from Embodiment 5 is that, in this embodiment, a limiting bolt 8 located on the lifting path of the lifting plate 4 is installed on the top of the frame 2 through a screw hole, and a locking nut 9 is installed on the limiting bolt 8.

[0055] like Figure 1 As shown, due to the above structure, when the lifting plate 4 is lowered to the lowest position, it abuts against the top of the limiting bolt 8. The function of the limiting bolt 8 is to limit the lowest position of the lifting plate 4, thereby limiting the horizontal sliding stroke of the back plate 3. By adjusting the height of the limiting bolt 8, the horizontal sliding stroke of the back plate 3 can be adjusted. Before adjustment, loosen the locking nut 9, and then rotate the limiting bolt 8 to raise or lower it. After the adjustment is completed, tighten the locking nut 9 to lock the height of the limiting bolt 8.

[0056] Example 7:

[0057] The difference from Embodiment 6 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the lifting plate 4 is floatingly mounted on the top of the frame 2 by multiple uprights 10, and each upright 10 is fitted with a lifting spring, with the bottom and top ends of each spring abutting against the bottom surface of the lifting plate 4 and the top surface of the frame 2, respectively.

[0058] like Figures 1 to 4 As shown, due to the above structure, when the external actuator drives the lifting plate 4 to move vertically, the lifting spring is compressed as the lifting plate 4 descends (stores elastic force), or releases elastic force as the lifting plate 4 rises (assisting in reset), making the vertical movement of the lifting plate 4 more stable and smooth.

[0059] The floating installation structure of the lifting plate 4, together with the transmission component 5, makes the horizontal movement of the moving die 101 driven by the back plate 3 more stable. During the simulation of the stamping action, the force and motion state of the moving die 101 are closer to the actual stamping scenario (but the speed is controllable).

[0060] Example 8:

[0061] The difference from Embodiment 7 is that, in this embodiment, in addition to the structural features of the aforementioned embodiments, the connector 6 includes a connecting groove 61, a connecting shaft 62, and a connecting plate 63. The connecting groove 61 is formed on the top surface of the back plate 3. The lower part of the connecting shaft 62 is slidably installed in the connecting groove 61, and the upper part is inserted into the connecting plate 63. The other end of the connecting plate 63 is fixed to the moving mold 101 by fasteners. The lower cross sections of the connecting groove 61 and the connecting shaft 62 are both larger at the bottom and smaller at the top.

[0062] In this embodiment of the application, the two ends of the transmission component 5 are respectively inserted into the two ends of the connecting groove 61.

[0063] like Figures 1 to 4 As shown, due to the above structure, quick connection is achieved: during debugging, the moving mold 101 is inserted into the connecting shaft 62 through the connecting plate 63, and the lower part of the connecting shaft 62 slides into the connecting groove 61 on the top surface of the back plate 3 (the connecting groove 61 and the lower part of the connecting shaft 62 adopt a cross-section design that is larger at the bottom and smaller at the top, such as a dovetail shape or a T shape, to ensure that the connecting shaft 62 will not come out upwards and the connection is stable), thus realizing a quick and detachable connection between the moving mold 101 and the back plate 3;

[0064] The two ends of the transmission component 5 are inserted into the two ends of the connecting groove 61 to limit the movement and prevent the connecting shaft 62 from coming out of the connecting groove 61.
