Description

Technical Field

[0001] This utility model relates to the field of die casting mold release and gripping technology, and in particular to a die casting mold gripping device for automatic waste removal. Background Technology

[0002] In the die-casting production industry, after the workpiece is formed by the die-casting mold, it needs to be removed from the mold through a demolding process, which is usually completed by a robot. Specifically, after the die-casting mold is opened, the robot reaches into the mold cavity to grab the formed workpiece, completes the demolding operation, and then transfers the workpiece and places it on a conveyor line. The conveyor line then transports the workpiece to the next dedicated station for the removal of waste materials such as gates and flash.

[0003] However, the existing "demolding and grabbing - conveying - dedicated waste removal" process has significant efficiency bottlenecks. On the one hand, the efficiency of waste removal is low. Because the waste removal process is completely separated from the die-casting process, there is a conveying waiting time between the workpiece being demolded and entering the waste removal station. Furthermore, the dedicated waste removal station often requires additional equipment and manpower for operation and coordination, resulting in insufficient continuity of the overall process and an extended production cycle for individual workpieces.

[0004] On the other hand, robotic arms experience significant wasted waiting time. In die-casting production, after a single workpiece is demolded, the production of the next workpiece requires a series of processes, including mold closing, molten material injection, and pressure holding. This process typically requires a certain time interval. During this period, the robotic arm that has completed the demolding and gripping task cannot participate in other operations and can only remain idle. However, existing robotic arms have limited functionality, only capable of demolding and unloading workpieces. They cannot utilize this waiting time to simultaneously remove waste from the gripped workpieces, resulting in underutilization of equipment resources and further hindering the overall efficiency improvement of the production line. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an automatic waste removal die-casting mold gripping device.

[0006] An automatic waste removal die-casting mold gripping device designed for this purpose includes a robotic arm, a gripping module, a frame, and a mold base;

[0007] The gripping module includes a connecting base fixedly connected to the robot arm, a gripping element disposed on the connecting base, and a pressing assembly;

[0008] The gripping element is used to grip the workpiece;

[0009] The pressing assembly is configured to correspond to the waste material of the workpiece and can move relative to the workpiece to press the waste material;

[0010] The mold base is used to insert and engage with the workpiece so that the workpiece is fixed on the mold base.

[0011] Preferably, the pressing assembly includes a pressing cylinder fixedly mounted on the connecting seat, and the cylinder shaft of the pressing cylinder is connected to a pressing plate.

[0012] Preferably, when the workpiece is gripped by the gripping element, the pressure plate and the waste material are in contact with each other.

[0013] Preferably, the mold base is provided in several units and is detachably connected to the frame.

[0014] Preferably, the gripping element is a pneumatic finger, and the gripping end of the pneumatic finger is connected to a claw.

[0015] Preferably, the gripping element is an electromagnet.

[0016] Preferably, the gripping element includes several vacuum adsorption components fixedly mounted on the connecting seat, each vacuum adsorption component having a hollow interior connected to a negative pressure connector; the lower surface of the vacuum adsorption component is the contact surface with the workpiece, and several negative pressure adsorption holes are provided on the lower surface of the vacuum adsorption component.

[0017] Compared with the prior art, this automatic waste removal die-casting mold gripping device, by integrating the synergistic effects of the robotic arm, gripping module, frame, and mold base, can significantly improve the overall efficiency and resource utilization of die-casting production. The specific beneficial effects are as follows:

[0018] First, the simultaneous operation of demolding and waste removal significantly shortens the production cycle. In the gripping module, after the gripping element completes the demolding and gripping of the workpiece, the pressing assembly can directly press the workpiece at the waste location, eliminating the need to transfer the workpiece to a dedicated waste removal station. This design breaks away from the traditional separate process of "demolding-conveying-waste removal," saving the workpiece's waiting time on the conveyor line and allowing the waste removal process to overlap with the die-casting process of the next workpiece, significantly reducing the total production time for a single workpiece.

[0019] Secondly, fully utilize the idle time of the robotic arm to improve equipment utilization. After the robotic arm completes demolding and grips the workpiece, during the cycle waiting for the next workpiece to be die-cast, the gripped workpiece can be de-wasted using the pressure assembly. Combined with the insertion and fixing structure between the mold base and the workpiece, this ensures the workpiece remains stable during the pressing and de-wasting process, avoiding processing deviations caused by displacement. This transforms the robotic arm from a single demolding and unloading tool into a composite device with both gripping and de-wasting functions, effectively reducing equipment idle time and improving the overall equipment efficiency of the production line.

[0032] See Figures 1-4 An automatic waste removal die-casting mold gripping device includes a robot arm 10, a gripping module 20, a frame 30, and a mold base 40. The gripping module 20 includes a connecting seat 200 fixedly connected to the robot arm 10, a gripping element 210 disposed on the connecting seat 200, and a pressing assembly 220. The gripping element 210 is used to grip a workpiece 50. The pressing assembly 220 is disposed corresponding to the waste material 60 of the workpiece 50 and can move relative to the workpiece 50 to press the waste material 60. The mold base 40 is used to insert and cooperate with the workpiece 50 so that the workpiece 50 is fixed on the mold base 40.

[0033] The working principle of this automatic waste removal die-casting mold gripping device is as follows:

[0034] After the die-casting mold completes the forming of workpiece 50 and opens, the robot arm 10 moves the gripping module 20 to the mold cavity, and the gripping element 210 actuates to grip workpiece 50, realizing the demolding operation of workpiece. Subsequently, the robot arm 10 carries the gripped workpiece 50 to the mold base 40, so that workpiece 50 and mold base 40 are inserted and fitted together, thereby firmly fixing workpiece 50 on mold base 40, providing a stable working foundation for subsequent waste removal processes.

[0035] After the workpiece 50 is fixed, the pressure assembly 220 is positioned corresponding to the scrap 60 of the workpiece 50. At this time, the pressure assembly 220 moves relative to the workpiece 50, precisely acting on the scrap 60 and pressing it. The force generated by the pressing separates the scrap 60 from the workpiece 50, completing the scrap removal operation.

[0036] During this process, the entire motion flow can be synchronized with the die-casting process of the next workpiece. That is, while waiting for the next workpiece to be formed, the robot arm 10 completes the above-mentioned gripping, fixing, and waste removal operations, making full use of the equipment's idle time and improving production efficiency. After the waste removal is completed, the gripping element 210 moves again to grip the processed workpiece 50, which is then transferred to the next stage by the robot arm 10. The mold base 40 then waits to cooperate with the next workpiece and enter the next work cycle.

[0037] See Figure 3 The pressing assembly 220 includes a pressing cylinder 221 fixedly mounted on the connecting seat 200, and a pressing plate 222 connected to the cylinder shaft of the pressing cylinder 221. In the pressing assembly 220, the pressing cylinder 221, fixedly mounted on the connecting seat 200, is the core component providing power. It can precisely output driving force through the extension and retraction of the cylinder shaft, ensuring stable and controllable power for the pressing action. The pressing plate 222, connected to the cylinder shaft, acts as the execution component directly acting on the workpiece scrap 60, increasing the contact area with the scrap and allowing the pressing force to be transmitted more evenly to the scrap. This avoids damage to the workpiece due to excessive localized force, while ensuring that the scrap separates smoothly from the workpiece under sufficient and uniform pressure.

[0038] Specifically, when the workpiece 50 is gripped by the gripping element 210, the pressure plate 222 and the waste material 60 are in contact with each other. The pre-fitting of the pressure plate 222 and the waste material 60 ensures that there are no gaps or misalignments between them, so that the driving force output by the pressure cylinder 221 can be directly and evenly applied to the waste material 60 through the pressure plate 222. This avoids situations where the local force is too large or too small due to poor contact, ensuring that the waste material can be removed smoothly and preventing damage to the workpiece body due to uneven force distribution, further ensuring the stability and reliability of the operation.

[0039] Specifically, several mold bases 40 are provided and detachably connected to the frame 30. The number and position of the mold bases 40 are set according to the specific situation of the workpiece 50.

[0040] In this invention, the gripping element 210 employs pneumatic fingers, and the gripping end of the pneumatic fingers is connected to a jaw. The gripping element uses pneumatic fingers, and the jaw connected to its gripping end can quickly open and close with the help of the pneumatic driving force of the pneumatic fingers. This allows for stable gripping of workpieces of different specifications, ensuring that the workpieces do not loosen or shift during demolding, transfer, and subsequent waste removal processes, providing a reliable gripping foundation for the entire operation.

[0041] In this invention, the gripping element 210 is an electromagnet. It uses electromagnetic force to attract iron-containing workpieces, providing rapid response and stable clamping, ensuring stable workpiece positioning during demolding, transfer, and waste removal, thus providing reliable gripping support for operations.

[0042] In this invention, the gripping element 210 includes several vacuum adsorption components 211 fixedly mounted on the connecting seat 200. Each vacuum adsorption component 211 is hollow and connected to a negative pressure connector 213. The lower surface of each vacuum adsorption component 211 is the contact surface with the workpiece 50, and several negative pressure adsorption holes 212 are provided on the lower surface of the vacuum adsorption component 211. When a negative pressure source is connected to the negative pressure connector 213, the several negative pressure adsorption holes 212 on its lower surface can quickly form a negative pressure environment, thereby tightly adsorbing the surface of the workpiece 50. This adsorption method does not require contact with the edges or complex structural parts of the workpiece 50, and is especially suitable for workpieces with flat surfaces, soft materials, or those easily scratched. It can effectively avoid mechanical damage to the workpiece 50 and ensure the appearance and structural integrity of the workpiece 50. Meanwhile, the arrangement of multiple vacuum adsorption components 211 disperses the adsorption force, and combined with the evenly distributed negative pressure adsorption holes 212, ensures that the adsorption force on the workpiece 50 is more balanced, guaranteeing that the workpiece 50 remains stable during demolding, transfer, and subsequent waste removal processes, and is less prone to displacement or detachment. Furthermore, vacuum adsorption offers a fast response speed; by controlling the on / off state of the negative pressure, the workpiece 50 can be quickly grasped and released, making operation convenient and efficient, and well-suited for the automated processes of die-casting production.
