Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a stamping die with rapid demolding. Background Technology

[0002] With the continuous development of industrial manufacturing, especially in the metal processing and plastic molding industries, the application of stamping technology is becoming increasingly widespread. Stamping dies, as important manufacturing tools, are widely used in the production of parts for industries such as automobiles, home appliances, and electronics. In traditional stamping processes, stamping dies often employ a single punch structure. However, in mass production, this traditional approach often faces problems such as low production efficiency, difficulty in demolding, and waste accumulation.

[0003] During the stamping process, the adhesion between scrap and the die surface is a common problem. After the stamping process is complete, the scrap usually adheres to the die surface, making it difficult to remove quickly. This not only affects the efficiency of the die but can also impact subsequent production. In particular, when the scrap is tightly bonded to the die surface, the demolding process becomes even more difficult, leading to production line stoppages and reduced stamping efficiency.

[0004] In view of this, we will study and improve the existing problems to provide a stamping die with fast demolding to solve the current problems. The aim is to solve the problems and improve the practical value through this technology. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art or related technologies.

[0006] This utility model relates to a stamping die for rapid demolding, which is particularly suitable for the efficient removal of scrap sheets in stamping operations. The die has a simple structure and high efficiency, effectively reducing the adhesion of scrap to the die surface during stamping, ensuring smooth demolding of both the workpiece and scrap sheets, thereby improving production efficiency and stamping accuracy.

[0007] The main technical features of this utility model are as follows:

[0008] The fixed mold base is the foundation of the mold, providing support and ensuring mold stability. A spring device is installed on the bottom surface of the fixed mold base to push the punching ring downwards, which is used to eject the inner sheet of the ejector core and assist in the ejection of the scrap sheet.

[0009] The die holder and the retracting core work together to punch the sheet material through relative motion. The retracting core pushes the sheet material during its downward movement, completing the punching action. Driven by the retracting core, the die core and the cutting ring perform precise punching; the top surface of the die core is annular and has an equal area to the bottom surface of the retracting core.

[0010] The demolding assembly includes a core-removing ring seat and a rotating ring assembly. The rotating ring assembly drives the core-removing ring seat to move relative to the core-removing ring seat through a drive motor, and lifts the scrap piece with its abutment teeth to ensure smooth separation of the scrap piece from the mold surface.

[0011] The rotating ring assembly and the core-removing ring seat rotate relative to each other. The abutment teeth are arranged radially along the surfaces of the core-removing ring seat and the rotating ring assembly. Through meshing and lifting actions, the waste sheet is demolded.

[0012] A spring device is installed on the bottom surface of the fixed mold base to ensure that the punching ring can descend quickly after punching, which helps the material sheet and waste to be discharged quickly.

[0013] This invention provides a highly efficient and reliable fast-release stamping die. Through precise design and structural matching, it solves the problem of scrap being difficult to remove during the stamping process. The meshing action between the rotating ring assembly and the core-removing ring seat prevents the scrap from sticking to the die surface, ensuring a smooth and stable demolding process.

[0014] This mold has the following advantages:

[0015] High efficiency: The precision structure of the demolding components enables rapid and efficient removal of waste sheets, reducing the time that waste remains during the production process.

[0016] Improved production efficiency: The quick demolding design of the mold reduces downtime caused by waste material adhesion, thereby improving production efficiency.

[0017] The quick-release stamping die of this invention is particularly suitable for manufacturing fields that require high-efficiency production and high-precision stamping, such as metal stamping and plastic processing industries, and has broad application prospects. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0028] The following is in conjunction with the appendix Figures 1-4 This invention describes a stamping die with rapid demolding, provided by some embodiments of the present invention.

[0029] Implementation Method 1: Overall Structure

[0030] like Figure 1 As shown, the quick-release stamping die of this utility model mainly includes a fixed die base 100, a punch die base 200, and a demolding assembly 300. The fixed die base 100 and the punch die base 200 cooperate with each other through the die core 110 and the ejector core 210 to complete the stamping operation. The demolding assembly 300 includes an ejector ring seat 310 and a rotating ring assembly 320, which achieves quick demolding through a special structural design, ensuring the smooth separation of the sheet metal and scrap sheet.

[0031] The fixed mold base 100 serves as the fixed base of the mold, providing support and ensuring the stability of the mold. The bottom surface of the fixed mold base 100 is equipped with a spring device to push the punching ring 220 to move downwards, for ejecting the inner sheet of the ejector core 210, and to help eject the stamped sheet and scrap.

[0032] The die core 110 is fixedly mounted on the fixed die base 100 and is responsible for guiding the work of the stamping die. The punching ring 220 is movably mounted on the bottom surface of the fixed die base 100 and sleeved inside the shear core 210. During the stamping process, the punching ring 220 performs relative shearing work with the die core 110 to achieve the punching of the sheet material. The shear core 210 and the punching ring 220 work relative to each other to ensure the smooth stamping of the sheet material; the top surface of the die core 110 is annular and has an equal area to the bottom surface of the shear core 210.

[0033] The die holder 200 is the upper part of the die, driving the shear core 210 to move downwards to ensure the punching accuracy of the sheet metal. The shear core 210 works opposite to the die holder 200, pushing the sheet metal during the downward movement to complete the punching.

[0034] Implementation Method 2: Demolding Component 300

[0035] The demolding assembly 300 includes a core ejector ring seat 310 and a rotating ring assembly 320. Through a rotation mechanism, the meshing action between the core ejector ring seat 310 and the rotating ring assembly 320 ensures the separation of the scrap sheet from the surface of the mold core 110 and the surface of the core ejector ring seat 310.

[0036] The core-removing ring seat 310 is slidably sleeved on the surface of the mold core 110, and the rotating ring assembly 320 is rotatably sleeved on the outer periphery of the mold core 110. Through relative movement, especially when the rotating ring assembly 320 rotates, the two drive the abutment teeth 340 to engage and lift, thereby achieving rapid release of the waste sheet.

[0037] The abutment teeth 340 are distributed on the bottom surface of the core-removing ring seat 310 and the top surface of the rotating ring assembly 320, and are evenly distributed in a circumferential direction. The abutment teeth 340 have an isosceles triangular cross section, which plays the role of lifting the scrap sheet during relative movement, ensuring that the scrap sheet is smoothly demolded.

[0038] A drive motor 330 is mounted on the surface of the fixed mold base 100 and is used to drive the rotating ring assembly 320 to rotate. The drive motor 330 drives the rotating ring assembly 320 to move relative to each other through rotation, thereby causing the core ejector ring 310 to perform a lifting action, ensuring that the waste piece is smoothly separated from the mold core 110 and the surface of the core ejector ring 310.

[0039] The working process of this utility model:

[0040] Stamping operation: During the stamping operation, the die holder 200 drives the retracting core 210 downward, and the die core 110 and the punching ring 220 work together to complete the punching of the sheet material. During the punching process, the sheet material and scrap sheet are stamped by the die holder 200 and the fixed die holder 100 through the cooperation of the die core 110 and the punching ring 220.

[0041] Demolding process: During the stamping retraction, the punching ring 220 descends, and the scrap piece adheres to the outer periphery of the die core 110 and the top surface of the core ejector ring seat 310, making demolding difficult. At this time, the drive motor 330 starts, driving the rotating ring assembly 320 to rotate. The meshing between the rotating ring assembly 320 and the core ejector ring seat 310 causes relative movement between the two, which generates a pushing effect through the abutment teeth 340, ensuring that the scrap piece smoothly detaches from the surface of the die core 110.

[0042] Vibration demolding: During the rotation of the rotating ring assembly 320, the core-removing ring seat 310 falls back under its own weight and re-engages with the rotating ring assembly 320. At this time, the impact vibration between the core-removing ring seat 310 and the rotating ring assembly 320 is transmitted to the mold core 110 and the punching ring 220 through high-frequency vibration, thereby effectively separating the waste sheet from the surface of the mold core 110 and completing the demolding process.
