[0002] In the industrial manufacturing sector, connecting plates, as key structural components connecting different parts, directly affect the overall assembly quality and production progress of the equipment due to their forming accuracy and production efficiency. Currently, connecting plates are typically mass-produced using stamping dies. Traditional stamping dies mainly consist of basic components such as an upper die base, a lower die base, and a forming structure. The upper and lower die bases are closed by a stamping cylinder to pressurize and form the sheet metal. In existing dies, after the connecting plate is formed, due to the pressure and material viscosity during the forming process, the workpiece often fits tightly against the forming groove of the upper die base or the pressure ring of the lower die base. Manual demolding is not only inefficient but also prone to workpiece deformation and surface scratches, affecting the product qualification rate. If rigid tools are used to assist in demolding, the risk of workpiece damage is further increased. Utility Model Content

Detailed Implementation

[0016] 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.

[0017] Example 1: This embodiment provides a high-efficiency positioning connecting plate mold, including: The housing 1 has a lower mold base 2 fixedly connected to the bottom of the inner wall of the housing 1. A forming block 5 for forming the connecting plate is formed on the lower mold base 2. A stamping cylinder 3 is fixedly connected to the top of the housing 1. The output end of the stamping cylinder 3 passes through the housing 1 and is fixedly connected to an upper mold base 4. A forming groove 6 adapted to the forming block 5 is formed in the upper mold base 4. A pressure ring 7 is installed around the periphery of the forming block 5. A guide groove 8 is provided on the pressure ring 7, and the guide groove 8 is recessed on the upper surface of the pressure ring 7. The lifting assembly is provided in the guide groove 8 for lifting the connecting plate from the pressure ring 7 after the connecting plate is formed; The upper mold base 4 is equipped with a push-out component that pushes the connecting plate away from the upper mold base 4 after the connecting plate is formed.

[0018] As can be seen in this embodiment, the shell 1, as the overall support frame of the mold, is made of high-strength steel to ensure the overall rigidity and stability of the mold. A lower mold base 2 is bolted to the bottom of the inner wall of the shell. A forming block 5 for forming the connecting plate is integrally formed on the lower mold base 2. The shape of the forming block 5 matches the contour of the lower surface of the connecting plate. A stamping cylinder 3 is fixedly connected to the top of the shell 1 via a flange. The output end of the stamping cylinder 3 passes through a pre-set through hole on the top of the shell 1 and is fixedly connected to an upper mold base 4 via a coupling. A forming groove 6, which matches the forming block 5, is recessed within the upper mold base 4. The shape of the forming groove 6 matches the contour of the upper surface of the connecting plate. When the stamping cylinder 3 drives the upper mold base 4 downwards… When the mold is lowered, the forming block 5 and the forming groove 6 close together, and the plate placed between them is pressed and formed to form a connecting plate. The pressure ring 7 is installed around the forming block 5, and its inner diameter is larger than the outer diameter of the forming block 5. It is used to press the edge of the plate during the stamping process to prevent the plate from wrinkling or shifting. The upper surface of the pressure ring 7 is recessed to form a guide groove 8. The guide groove 8 is evenly distributed around the pressure ring 7 to provide installation and movement space for the lifting component. The lifting component is used to lift the connecting plate from the pressure ring 7 after it is formed to achieve automatic demolding of the lower mold end. The push component is set in the upper mold base 4 to push the connecting plate away from the forming groove 6 of the upper mold base 4 after it is formed to prevent the workpiece from sticking to the upper mold base 4.

[0019] Example 2: This embodiment provides a high-efficiency positioning connecting plate mold, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0020] The lifting assembly includes: Lifting block 9 is movably disposed within guide groove 8; The first elastic element 10 is disposed on the lower side of the lifting block 9 and is contained in the guide groove 8. It can apply an elastic force to the lifting block 9 so that the lifting block 9 remains protruding from the upper surface of the pressure ring 7 when there is no external pressure.

[0021] As can be seen from this embodiment, the lifting block 9 is made of wear-resistant alloy material and can slide up and down along the inner wall of the guide groove 8. The upper surface of the lifting block 9 is in contact with the connecting plate. To ensure that the connecting plate is subjected to uniform force, the upper surface of the lifting block 9 is designed as an arc or planar structure that matches the edge contour of the connecting plate. The first elastic element 10 is a high-strength compression spring, which is set on the lower side of the lifting block 9 and accommodated in the spring mounting hole preset at the bottom of the guide groove 8. One end of the first elastic element 10 is fixedly connected to the bottom of the lifting block 9, and the other end is fixedly connected to the bottom of the guide groove 8. When there is no external force, the elastic force of the first elastic element 10 keeps the lifting block 9 protruding from the upper surface of the pressure ring 7. When the mold is closed, the upper mold base 4 presses down on the lifting block 9, compressing the first elastic element 10 and causing the lifting block 9 to retract into the guide groove 8. After the mold is opened, the first elastic element 10 resets, pushes the lifting block 9 up, and lifts the connecting plate off the pressure ring 7 to achieve automatic demolding.

[0022] Example 3: This embodiment provides a high-efficiency positioning connecting plate mold, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0023] The push component includes: Mounting groove 11 is formed by recessing the lower surface of the forming groove 6 of the upper mold base 4; The pusher housing 12 is installed in the mounting groove 11; Push block 13 is movably connected inside push shell 12. One end of push block 13 has an enlarged diameter section 14. The diameter of the outlet end of push shell 12 is smaller than the outer diameter of enlarged diameter section 14. The second elastic element 15 is provided inside the push shell 12, and one end of the second elastic element 15 is fixedly connected to the inner wall of the push shell 12, and the other end is fixedly connected to the enlarged diameter portion 14.

[0024] As can be seen in this embodiment, the lower surface of the molding groove 6 of the upper mold base 4 is recessed to form an installation groove 11. The number and position of the installation grooves 11 are determined according to the structural characteristics of the connecting plate, and are preferentially set in the areas where the connecting plate is prone to adhesion. The push shell 12 adopts a cylindrical structure and is fixedly installed in the installation groove 11 by interference fit or bolts. The push block 13 can slide along the inner wall of the push shell 12. The lower end of the push block 13 is designed as a hemispherical or arc-shaped structure to avoid scratching the surface of the connecting plate. The upper end of the push block 13 forms an expanded diameter section 14. The diameter of the outlet end of the push shell 12 is smaller than that of the upper mold base 4. The outer diameter of the expanded diameter section 14 can prevent the push block 13 from falling out of the push shell 12. The second elastic element 15 is a high-precision compression spring and is set inside the push shell 12. One end of the second elastic element 15 is fixedly connected to the inner wall of the push shell 12, and the other end is fixedly connected to the expanded diameter section 14. When the mold is closed, the connecting plate applies pressure to the push block 13, causing the second elastic element 15 to compress and the push block 13 to retract into the push shell 12. After the mold is opened, the second elastic element 15 is reset, pushing the push block 13 downward and pushing the connecting plate away from the forming groove 6, thereby realizing automatic demolding of the upper mold end.

The cylinder of the gas spring is fixed in the lower mold base 2. The top of the piston rod is fixedly connected to the bottom of the pressure ring 7. The gas spring can adjust the air pressure to preset the support pressure, so as to ensure that the pressure ring 7 presses the edge of the plate evenly and stably, avoids the deformation of the plate caused by the fluctuation of the pressing force, and plays a buffering role in the mold closing and opening process, reducing the impact damage of the mold components.

[0028] Example 5: This embodiment provides a high-efficiency positioning connecting plate mold, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0030] As can be seen in this embodiment, a safety door 17 is provided at the operating opening on one side of the housing 1. The size of the safety door 17 is adapted to the size of the operating opening of the housing 1 to ensure complete coverage of the opening. T-shaped slide grooves 18 are provided on both sides of the housing 1. The T-shaped slide grooves 18 extend vertically to guide the lifting and lowering of the safety door 17. The T-shaped slider 19 is made of high-strength plastic or metal and slides in cooperation with the T-shaped slide groove 18. One end of the T-shaped slider 19 is fixedly connected to the two side edges of the safety door 17 to ensure that the safety door 17 rises and falls smoothly along the T-shaped slide groove 18 without deviation or jamming. The push cylinder 20 is fixedly connected to the top of the housing 1 through a bracket. The output end of the push cylinder 20 passes through a pre-set guide hole at the top of the housing 1 and is fixedly connected to the top of the safety door 17 through a connecting block 21. The connecting block 21 ensures that the driving force of the push cylinder 20 is smoothly transmitted to the safety door 17. The push cylinder 20 drives the safety door 17 to rise and fall, realizing the opening and closing of the operating opening. When the safety door 17 is completely closed, the mold restarts the stamping action to prevent safety accidents.
