Description
Technical Field
[0001] This utility model belongs to the field of mold technology, specifically relating to a balanced separation structure and a mold. Background Technology
[0002] In the sheet metal processing field of the hardware industry, the operation method of mold installation, adjustment and maintenance directly affects production efficiency and mold life.
[0003] Both of the current mainstream operating methods have significant drawbacks. The first method relies on the mold disassembly and repair using a punch press. This involves locking the mold on the punch press, operating the press to open the upper and lower mold modules, and then using a forklift to separate the upper and lower mold modules and remove them from the machine. This method is not only cumbersome but also consumes machine resources. The second method involves directly using heavy blows to forcibly pry open and separate the upper and lower mold modules. This method is not only time-consuming and labor-intensive but also damages the precision of the mold, leading to a sharp decrease in its lifespan. Summary of the Invention
[0004] To address the shortcomings of the prior art, this utility model provides a balanced separation structure and mold that can easily open the mold in the closed state without occupying machine resources or damaging the precision of the mold.
[0005] The technical effects to be achieved by this utility model are realized through the following technical aspects: This utility model provides a balanced separation structure, which includes a rotating body, a first screw, and a second screw; The rotating body includes a first end and a second end extending in opposite directions. A first internal thread is formed in the first end, and a second internal thread is formed in the second end. The rotation directions of the first internal thread and the second internal thread are opposite. The first screw is threaded to the first end, and the second screw is threaded to the second end; Rotate the rotating body along a first direction so that the first end unscrews the first screw and the second end unscrews the second screw; rotate the rotating body along a second direction so that the first end screws into the first screw and the second end screws into the second screw. The first direction is opposite to the second direction.
[0006] In some implementations, the outer surface of the rotating body is knurled. The knurling design increases the friction of the outer surface of the rotating body, prevents the rotating body from slipping in the hand, and makes it easier to rotate the rotating body by hand.
[0007] In some implementations, a first through hole is provided at the center of the rotating body in the axial direction along the radial direction; The first through hole is used to insert an L-shaped wrench, which makes it easier to rotate the rotating body and improves the convenience of operation.
[0008] In some implementations, a second through hole is provided at the center of the rotating body in the axial direction along the radial direction; The second through hole is used to insert an L-shaped wrench; The first through hole is perpendicular to the second through hole, increasing the number and position of through holes into which an L-shaped wrench can be inserted, making it easier for the operator to select the through hole that is convenient for operation.
[0009] This utility model also provides a mold, including an upper mold module, a lower mold module, and the balanced separation structure described in any one of the above. The balanced separation structure is located between the upper mold module and the lower mold module, and the second screw is fixedly connected to the lower mold module; In the closed mold state, the rotating body is rotated along the first direction, the first end unscrews the first screw, the second end unscrews the second screw, and the first screw pushes the upper mold module upward. With the help of the balanced separation structure, the upper mold module and the lower mold module in the closed mold state can be easily opened.
[0010] In some implementations, there are two balancing separation structures, which are symmetrically arranged between the upper mold module and the lower mold module, so that the operator can open the upper mold module and the lower mold module in the closed state more evenly.
[0011] In some implementations, the upper mold module includes an upper support plate, an upper mold base, an upper mold assembly, and a punch; The upper support plate, the upper die base, and the upper die assembly are connected in sequence from top to bottom. The upper end of the punch is embedded in the upper die assembly, and the lower end of the punch is exposed at the lower end of the upper die assembly. In the closed mold state, there is a gap between the first screw and the upper mold base, so as to avoid affecting the mold closing requirements of the upper mold module and the lower mold module during normal operation.
[0012] In some implementations, the lower mold module includes a lower template, a lower pad, and a lower mold base connected sequentially from top to bottom; The second screw is fixedly connected to the lower mold base to prevent the second screw from rotating.
[0013] In some implementations, an upper top module embedded in the lower mold module is also included; The upper mold module includes an elastic element and an ejector pin. One end of the elastic element is fixedly connected to the lower mold module, and the other end of the elastic element is connected to the ejector pin. When the elastic element is extended, the ejector pin protrudes from the upper end of the lower mold module. The upper ejector module can push the material upwards, facilitating material removal.
[0014] In some implementations, a guide module for mold closure alignment is also provided between the upper mold module and the lower mold module to ensure the alignment accuracy of the upper mold module and the lower mold module during the closure process.
[0015] In summary, this utility model has at least the following advantages: 1. The present invention provides a balanced separation structure in which a first internal thread is formed in the first end of the rotating body and a second internal thread is formed in the second end of the rotating body, and the first internal thread and the second internal thread rotate in opposite directions, so that when the rotating body is rotated, the mold in the closed state can be easily opened by pushing outward with the help of the balanced force of the first screw and the second screw.
[0016] 2. The mold provided by this utility model, by applying a balanced separation structure, ensures that the upper mold module and the lower mold module do not occupy machine resources or damage the precision of the mold during the opening and closing process. Attached Figure Description

Detailed Implementation
[0018] To facilitate understanding of the present invention, a more comprehensive description will be given below in conjunction with the accompanying drawings and specific embodiments. The drawings illustrate preferred embodiments of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0022] Example 1: Please see Figures 1-3 A balanced separation structure 100 is provided, which can easily open the mold in the closed state. Of course, it is also suitable for the balanced separation requirements of the first module and the second module with closed connection.
[0023] The balanced separation structure 100 includes a rotating body 110, a first screw 120, and a second screw 130. The rotating body 110 is a cylindrical structure, including a first end 111 and a second end 112 extending in opposite directions. A first internal thread 111a is formed in the first end 111, and a second internal thread 112a is formed in the second end 112. The first internal thread 111a and the second internal thread 112a rotate in opposite directions.
[0024] Understandably, a first connecting groove is formed inward at the first end 111, and a first internal thread 111a is formed on the groove wall of the first connecting groove. A second connecting groove is formed inward at the second end 112, and a second internal thread 112a is formed on the groove wall of the second connecting groove.
[0025] The first screw 120 is threaded to the first end 111, and the second screw 130 is threaded to the second end 112. That is, the first screw 120 has a first external thread for threaded connection with the internal thread of the first end 111, and the second screw 130 has a second external thread for threaded connection with the internal thread of the second end 112.
[0026] When applying this balanced separation structure to meet the balanced separation requirements of the first and second modules in a closed connection, the balanced separation structure can be placed between the first and second modules. For example, the first module is located at the upper end of the second module, the second screw 130 is limited to the second module and will not rotate, and there is a gap between the first screw 120 and the first module. The existence of this gap indicates that the distance between the first and second modules can accommodate the balanced separation module, that is, the distance between the first and second modules is greater than the height of the balanced separation module, so that the balanced separation module can be inserted between the first and second modules.
[0027] For ease of understanding, the first module and the second module are defined here as the upper mold module and the lower mold module of the mold in the sheet metal operation, respectively. In the closed mold state, the lower middle part of the upper mold module is closed and connected to the upper middle part of the lower mold module. There is a distance between the edges of the upper mold module and the lower mold module, which is greater than the height of the balance separation module.
[0028] After the second screw 130 is fixedly connected to the edge of the lower mold module, the rotating body 110 is rotated along the first direction X, so that the first end 111 unscrews the first screw 120 and the second end 112 unscrews the second screw 130, thereby making the upper mold module and the lower mold module appear in the mold open state.
[0029] It should be noted that in the initial stage of rotating the main body 110, since the second screw 130 is fixedly connected to the edge of the lower mold module, the position of the second screw 130 will not rotate. However, there is a gap between the first screw 120 and the upper mold module, so the first screw 120 will rotate with the main body 110. As the main body 110 gradually rotates away from the second screw 130, the first screw 120 abuts against the lower end of the upper mold module. The position of the first screw 120 will be affected by the gravity of the upper mold module and will not rotate. As the main body 110 continues to rotate, the main body 110 gradually rotates out the first screw 120 and the second screw 130, while the upper mold module is pushed upward by the upward force of the first screw 120, separating from the lower mold module and presenting an open mold state.
[0030] Similarly, when it is necessary to restore the state of the balanced separation structure, the rotating body 110 is rotated along the second direction Y, so that the first end 111 is screwed into the first screw 120 and the second end 112 is screwed into the second screw 130; wherein, the first direction X is opposite to the second direction Y.
[0031] This embodiment provides a balanced separation structure in which a first internal thread 111a is formed in the first end 111 of the rotating body 110, and a second internal thread 112a is formed in the second end 112 of the rotating body 110. The first internal thread 111a and the second internal thread 112a rotate in opposite directions, so that when the rotating body 110 is rotated, it can be pushed outward by the balancing force of the first screw 120 and the second screw 130, and the mold in the closed state can be easily opened.
[0032] Example 2: This embodiment makes further structural optimizations based on Embodiment 1. Please refer to... Figures 1-3 Based on the above Figure 4 .
[0033] In this embodiment, the outer surface of the rotating body 110 is knurled. The knurling design can increase the friction of the outer surface of the rotating body 110, prevent the rotating body 110 from sliding in the hand, and make it easy to rotate the rotating body 110 by hand.
[0034] For example, knurling can be either grid knurling or striped knurling, as long as it serves to increase friction.
[0035] In some embodiments, a first through hole 113 is provided in the radial direction at the center of the rotating body 110 in the axial direction; the first through hole 113 is used to insert an L-shaped wrench, which makes it easier to rotate the rotating body 110 and improves the convenience of operation.
[0036] For example, after inserting the first end of the L-shaped wrench into the first through hole 113, the second end of the L-shaped wrench can be rotated to drive the rotating body 110 to rotate. Compared with manually rotating the rotating body 110, the L-shaped wrench can reduce the force used and make it easier to rotate the rotating body 110.
[0037] Furthermore, a second through hole 114 is provided in the radial direction at the center of the rotating body 110 in the axial direction; the second through hole 114 is used to insert an L-shaped wrench; the first through hole 113 is perpendicular to the second through hole 114, increasing the number and position of through holes that can insert an L-shaped wrench, making it easier for the operator to select a through hole that is convenient for operation.
[0038] Example 3: This embodiment makes further structural optimizations based on Embodiment 1. Please refer to... Figures 1-3 Based on the above Figure 5 and Figure 6 .
[0039] This embodiment provides a mold, including an upper mold module 200, a lower mold module 300, and the balanced separation structure in embodiment 1 or 2 above.
[0040] The balanced separation structure is located between the upper mold module 200 and the lower mold module 300, and the second screw 130 is fixedly connected to the lower mold module 300. In the closed mold state, the rotating body 110 is rotated along the first direction X, the first end 111 unscrews out the first screw 120, the second end 112 unscrews out the second screw 130, and the first screw 120 pushes the upper mold module 200 upward. With the help of the balanced separation structure, the upper mold module 200 and the lower mold module 300 in the closed mold state can be easily opened.
[0041] Specifically, in the closed mold state, the lower middle part of the upper mold module 200 is closedly connected to the upper middle part of the lower mold module 300, and there is a distance between the edges of the upper mold module 200 and the lower mold module 300, which is greater than the height of the balance separation module.
[0042] After the second screw 130 is fixedly connected to the edge of the lower mold module 300, the rotating body 110 is rotated along the first direction X, so that the first end 111 unscrews the first screw 120 and the second end 112 unscrews the second screw 130, thereby making the upper mold module 200 and the lower mold module 300 appear in the mold open state.
[0043] In the initial stage of rotating the rotating body 110, since the second screw 130 is fixedly connected to the edge of the lower mold module 300, the position of the second screw 130 will not rotate. However, there is a gap between the first screw 120 and the upper mold module 200, so the first screw 120 will rotate with the rotating body 110. When the rotating body 110 gradually rotates away from the second screw 130, the first screw 120 abuts against the lower end of the upper mold module 200. The position of the first screw 120 will not rotate due to the gravity of the upper mold module 200. As the rotating body 110 continues to rotate, the rotating body 110 gradually rotates out the first screw 120 and the second screw 130, while the upper mold module 200 is pushed upward by the upward force of the first screw 120, separating from the lower mold module 300, and is in the open mold state.
[0044] Furthermore, there are two balancing separation structures, which are symmetrically arranged between the upper mold module 200 and the lower mold module 300, so that the operator can open the upper mold module 200 and the lower mold module 300 in the closed state more evenly.
[0045] In some embodiments, the upper mold module 200 includes an upper support plate 210, an upper mold base 220, an upper mold assembly 230, and a punch 240. The upper support plate 210, the upper mold base 220, and the upper mold assembly 230 are connected sequentially from top to bottom. The upper support plate 210 is used to connect the upper mold module 200 to the machine tool so that it can be moved upward or downward by the driving force of the machine tool. The upper mold base 220 is used to install and fix the upper mold assembly 230. The upper end of the punch 240 is embedded in the upper mold assembly 230, and the lower end of the punch 240 is exposed at the lower end of the upper mold assembly 230. In the closed mold state, the punch 240 can perform corresponding stamping operations on the material.
[0046] The first screw 120 is relative to the upper mold base 220. In the closed mold state, there is a gap between the first screw 120 and the upper mold base 220 to avoid affecting the mold closing requirements of the upper mold module 200 and the lower mold module 300 during normal operation.
[0047] Specifically, the first screw 120 is positioned relative to the edge of the upper mold base 220, avoiding the installation positions of the upper mold base 220, upper mold assembly 230, etc. There is a gap between the first screw 120 and the upper mold base 220, which facilitates the insertion of the balancing separation structure between the upper mold base 220 and the lower mold module 300. Alternatively, in the mold's open state during normal use, the second screw 130 can be fixedly connected to the lower mold module 300, and the rotating body 110 can be connected to the first screw 120 and the second screw 130 respectively. In this way, the balancing separation structure is directly locked onto the mold, and the rotating body 110 can be rotated whenever the mold needs to be opened. The gap between the first screw 120 and the upper mold base 220 will not affect the mold's closing operation during normal use.
[0048] Furthermore, the lower mold module 300 includes a lower template 310, a lower pad 320, and a lower mold base 330 connected sequentially from top to bottom; the second screw 130 is fixedly connected to the lower mold base 330 to prevent the second screw 130 from rotating.
[0049] In some embodiments, the mold further includes an upper ejector module 400 embedded in the lower mold module 300; the upper ejector module 400 includes an elastic element 410 and an ejector pin 420, one end of the elastic element 410 is fixedly connected to the lower mold module 300, and the other end of the elastic element 410 is connected to the ejector pin 420; when the elastic element 410 is extended, the ejector pin 420 protrudes from the upper end of the lower mold module 300, and the upper ejector module 400 can push the material upward, which is convenient for unloading.
[0050] In the open mold state, the elastic element 410 extends upward, causing the ejector pin 420 to protrude from the upper end of the lower mold module 300, pushing the material upward for easy unloading; in the closed mold state, the elastic element 410 contracts under the downward pressure of the ejector pin 420, preventing the ejector pin 420 from affecting the normal operation of the mold.
[0051] Furthermore, a guide module 500 for mold closure alignment is provided between the upper mold module 200 and the lower mold module 300. The guide module 500 can ensure the alignment accuracy of the upper mold module 200 and the lower mold module 300 during the closure process.
[0052] The guide module 500 includes a guide post and a guide sleeve. The guide post is embedded in the upper mold module 200, and the lower end of the guide post protrudes from the lower end face of the upper mold module 200. The guide sleeve is embedded in the upper end of the lower mold module 300, and the opening of the guide sleeve faces the guide post. When the upper mold module 200 moves downward under external driving force, it drives the guide post to move downward, so that the guide post passes through the guide groove, thereby achieving the alignment accuracy of the upper mold module 200 and the lower mold module 300 during the closing process.
[0053] The above description is merely an example and illustration of the structure of this invention, and while the description is specific and detailed, it should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these obvious substitutions all fall within the protection scope of this invention.
