Description

TECHNICAL FIELD

[0001] The application relates to the technical field of a stamping die, in particular to a metal steel ring full-silicone production die. BACKGROUND

[0002] A sealing ring with a special structure is known, which is characterized in that the cross section is provided with L-shaped grooves at the upper and lower ends, which are not connected to each other, and the L-shaped groove at the upper end of the steel ring wraps silicone in it.

[0003] In the prior art, two sets of molds are needed to process the sealing ring, one set is used to press the steel sheet and the silicone together to form the upper half of the steel ring, and the other set is used to press the lower half of the steel sheet to form the L-shaped groove at the lower end. Although this can process the sealing ring, the operation steps of using the two sets of molds are relatively complicated, and therefore a metal steel ring full-silicone production die is needed. CONTENT OF THE UTILITY MODEL

[0004] In view of the deficiencies in the prior art, the purpose of the application is to provide a metal steel ring full-silicone production die to solve the technical problem of complicated processing steps for the sealing ring with a special structure in the prior art.

[0005] The above-mentioned purpose of the application is achieved by the following technical scheme: a metal steel ring full-silicone production die, comprising an upper die seat, a lower die seat and a middle die seat placed on the lower die seat, and a forming structure for forming a steel sheet into a sealing ring is arranged on the middle die seat and the upper die seat.

[0006] Further, the forming structure comprises a casting cavity arranged on the working surface of the upper die seat, a connecting cavity arranged on the upper surface of the middle die seat for cooperating with the casting cavity to form the upper half of the sealing ring, and a forming cavity arranged on the bottom surface of the middle die seat for cooperating with the casting cavity to form the lower half of the sealing ring.

[0007] By adopting the above-mentioned technical scheme, first, the connecting cavity of the middle die seat is placed on the casting cavity on the working surface of the upper die seat on the lower die seat, then the steel sheet is placed in the connecting cavity of the middle die seat, then the silicone ring is placed on the steel sheet, then the upper die seat is pressed, so that the upper die seat is attached to the middle die seat, the connecting cavity and the casting cavity form a mold cavity for the upper half of the sealing ring, and the steel sheet and the silicone ring are formed into the upper half of the sealing ring, then the mold is separated, at this time the upper die seat with the steel sheet and the silicone ring is separated from the middle die seat, then the middle die seat is turned over so that the forming cavity faces the casting cavity, the mold is closed again so that the forming cavity and the casting cavity form a mold cavity for the lower half of the sealing ring, and the lower half of the steel sheet is formed into the lower half of the sealing ring, thereby forming a complete sealing ring, so that the worker can form the entire sealing ring without replacing the mold, reducing the processing steps and improving the work efficiency.

[0008] Further, the lower die set is provided with an adjusting structure for facilitating the turning of the middle die seat.

[0009] Further, the adjusting structure comprises a receiving space provided on the lower die set for the turning of the middle die seat, and an adjusting shaft arranged outside the lower die seat and fixedly connected to the middle die seat and extending into the receiving space, the adjusting shaft being rotatably connected to the lower die seat.

[0010] By adopting the above technical scheme, although the middle die seat and the forming structure are provided, the worker can form the entire sealing ring without replacing the die, thereby reducing the processing steps and improving the work efficiency. However, when the worker turns the middle die seat, it is difficult to control the position of the middle die seat, which may cause the forming structure to be misaligned after the middle die seat is turned, resulting in processing failure. The adjusting structure solves this technical problem. When the middle die seat needs to be turned, the adjusting shaft is rotated to turn the middle die seat, thereby completing the turning of the middle die seat. After the turning is completed, the position of the middle die seat does not change, which makes it easier for the worker to turn the middle die seat.

[0011] Further, the receiving space is provided with a connecting shaft coaxial with the adjusting shaft and extending away from one side of the adjusting shaft, one end of the connecting shaft being rotatably connected to the lower die seat, and the other end being fixedly connected to the middle die seat.

[0012] By adopting the above technical scheme, the connecting shaft can provide support to the side of the middle die seat away from the adjusting shaft, making the connection between the middle die seat and the adjusting shaft more stable and making the rotation of the middle die seat more effortless.

[0013] Further, the lower die seat is provided with a limiting structure on both sides of the outer portion for fixing the middle die seat.

[0014] Further, the limiting structure comprises a plug-in port provided on the outer portion of the lower die seat and extending through the receiving space, a connecting port provided on the side surface of the middle die seat and opposite to the plug-in port, and a limiting plate inserted through the lower die seat and into the connecting port through the plug-in port.

[0015] By adopting the above technical scheme, although the adjusting structure makes it easier for the worker to turn the middle die seat, when the mold is closed, the upper die seat will exert pressure on the middle die seat, which may cause the middle die seat to tilt slightly, resulting in processing errors. The limiting structure solves this technical problem. After the middle die seat is turned, the limiting plate is aligned with the plug-in port, and then the limiting plate is pushed to insert the limiting plate into the connecting port through the lower die seat, thereby limiting the rotation of the middle die seat and preventing processing errors.

[0016] Further, the end of the adjusting shaft away from the lower die seat is provided with an elongated alignment handle.

[0017] By adopting the technical scheme, the alignment handle can not only be conveniently rotated and adjusted by the staff, but also enable the staff to determine how many degrees the middle die seat is rotated, for example, the alignment handle is straight in the initial state, and is vertical after being rotated, that is, the middle die seat is rotated by 90 degrees, and if it is still straight after being rotated, it is 180 degrees, so that the staff can more conveniently align the connecting port with the plug-in port after rotating the middle die seat, so as to limit the rotation of the middle die seat by the limiting plate.

[0018] To sum up, the present application has at least one of the following beneficial technical effects:

[0019] 1. By arranging the middle die seat and the forming structure, the connecting cavity of the middle die seat is first placed on the lower die seat towards the casting cavity on the working surface of the upper die seat, then the steel sheet is placed in the connecting cavity of the middle die seat, then the silica gel ring is placed on the steel sheet, then the oil pressure upper die seat is used to make the upper die seat adhere to the middle die seat, so that the connecting cavity and the casting cavity form a mold cavity of the upper half of the sealing ring, and the steel sheet and the silica gel ring are formed into the upper half of the sealing ring, then the mold is opened, at this time the upper die seat with the steel sheet and the silica gel ring is separated from the middle die seat, then the middle die seat is turned over to make the forming cavity face the casting cavity, and the mold is closed again to make the forming cavity and the casting cavity form a mold cavity of the lower half of the sealing ring, and the lower half of the steel sheet is formed into the lower half of the sealing ring, thereby forming a complete sealing ring, so that the staff can form the entire sealing ring without replacing the mold, thereby reducing the processing steps and improving the work efficiency.

DETAILED DESCRIPTION

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] Embodiment, refer to Figure 1 and Figure 2, metal steel ring full package silica gel production mold, including the upper die seat 1, the lower die seat 2 and the middle die seat 3 placed on the lower die seat 2. On the middle die seat 3 and the upper die seat 1, the forming structure 4 is arranged, which is designed for the steel sheet to be shaped into a sealing ring. Specifically, the forming structure 4 is composed of the casting cavity 40 opened on the working surface of the upper die seat 1, the connecting cavity 41 opened on the upper surface of the middle die seat 3 and matched with the casting cavity 40 to form the upper half of the sealing ring, and the forming cavity 42 opened on the bottom surface of the middle die seat 3 and cooperated with the casting cavity 40 to form the lower half of the sealing ring.

[0025] Firstly, the connecting cavity 41 of the middle die seat 3 is accurately aligned with the casting cavity 40 on the working surface of the upper die seat 1, and the middle die seat 3 is placed on the lower die seat 2. Then, the steel sheet to be processed is placed in the connecting cavity 41 of the middle die seat 3, and then the silica gel ring is placed on the steel sheet, preparing for the subsequent forming step. Then, the upper die seat 1 is driven to descend by the oil pressure equipment, so that it closely fits the middle die seat 3. At this time, the connecting cavity 41 and the casting cavity 40 perfectly match to form the mold cavity of the upper half of the sealing ring. In this close fitting process, the steel sheet and the silica gel ring are accurately formed into the upper half of the sealing ring under the action of the mold.

[0026] After the upper half is formed, the mold is opened, and at this time, the upper die seat 1 with the preliminarily formed steel sheet and silica gel ring (i.e. the upper half of the sealing ring) smoothly separates from the middle die seat 3. Next, the middle die seat 3 is turned over, so that the forming cavity 42 opened on the bottom surface of the middle die seat 3 faces the direction of the original casting cavity 40. The mold is closed again, and the forming cavity 42 and the casting cavity 40 closely cooperate to form the mold cavity of the lower half of the sealing ring. In this step, the remaining part of the steel sheet is accurately formed into the lower half of the sealing ring.

[0027] Through the above-mentioned consecutive and efficient operation steps, a complete sealing ring is born. This setting enables the staff to complete the entire sealing ring forming process at one time without frequent mold replacement, which not only significantly reduces the processing steps, but also greatly improves the production efficiency and work efficiency.

[0028] Although the setting of the middle die seat 3 and the forming structure 4 makes the workers not need to change the die to form the whole sealing ring, reduces the processing steps and improves the work efficiency, but when the workers turn over the middle die seat 3, it is not easy to control the position of the middle die seat 3, which may cause the forming structure 4 to be misaligned after the workers turn over the middle die seat 3, resulting in processing failure. In order to solve this technical problem, the adjusting structure 5 is arranged in the lower die set in the embodiment, the adjusting structure 5 includes the receiving space 50 arranged on the lower die set for turning over the middle die seat 3 and the adjusting shaft 51 arranged outside the lower die seat 2 and fixedly connected to the middle die seat 3 and extending into the receiving space 50, and the adjusting shaft 51 is rotatably connected to the lower die seat 2. When the middle die seat 3 needs to be turned over, the adjusting shaft 51 is only needed to be rotated to drive the middle die seat 3 to turn over, so that the turning over of the middle die seat 3 is completed. After the turning over is completed, the position of the middle die seat 3 does not change, so that the workers can turn over the middle die seat 3 more easily.

[0029] In the embodiment, the one side of the receiving space 50 away from the adjusting shaft 51 extends the connecting shaft 52 coaxial with the adjusting shaft 51, one end of the connecting shaft 52 is rotatably connected to the lower die seat 2, and the other end is fixedly connected to the middle die seat 3. The connecting shaft 52 can provide support for the one side of the middle die seat 3 away from the adjusting shaft 51, so that the connection between the middle die seat 3 and the adjusting shaft 51 is more stable, and the rotation of the middle die seat 3 is more easy.

[0030] Although the setting of the adjusting structure 5 makes the workers turn over the middle die seat 3 more easily, but when the mold is closed, the upper die seat 1 will exert pressure on the middle die seat 3, which may cause the middle die seat 3 to slightly tilt, resulting in processing error. In order to solve this technical problem, the limiting structure 6 for fixing the middle die seat 3 is arranged on the two sides of the lower die seat 2. The limiting structure 6 includes the plug-in port 60 arranged on the lower die seat 2 and extending into the receiving space 50, the connecting port 61 arranged on the side surface of the middle die seat 3 opposite to the plug-in port 60, and the limiting plate 62 inserted into the connecting port 61 through the plug-in port 60 and the lower die seat 2. After the middle die seat 3 is turned over, the limiting plate 62 is aligned with the plug-in port 60, and then the limiting plate 62 is pushed to be inserted into the connecting port 61 through the lower die seat 2, so as to limit the rotation of the middle die seat 3 and prevent processing error.

[0031] In the embodiment, the one end of the adjusting shaft 51 away from the lower die seat 2 is provided with the long strip alignment handle 53. The alignment handle 53 not only can facilitate the workers to rotate the adjusting shaft 51, but also can make the workers to determine how many degrees the middle die seat 3 is rotated. For example, the alignment handle 53 is a straight line in the initial state, and becomes vertical after being rotated, that is, the middle die seat 3 is rotated by 90 degrees. If it is still a straight line after being rotated, it is 180 degrees. Therefore, the workers can more conveniently align the connecting port 61 with the plug-in port 60 after rotating the middle die seat 3, so as to limit the rotation of the middle die seat 3 by the limiting plate 62.

[0032] Specific implementation process: first, the connection cavity 41 of the middle die seat 3 is placed on the lower die seat 2 towards the casting cavity 40 on the working surface of the upper die seat 1, then the steel sheet is placed in the connection cavity 41 of the middle die seat 3, then the silica gel ring is placed on the steel sheet, then the upper die seat 1 is pressed by oil pressure, so that the upper die seat 1 is attached to the middle die seat 3, so that the connection cavity 41 and the casting cavity 40 form a mold cavity of the upper half of the sealing ring, and the steel sheet and the silica gel ring are formed into the upper half of the sealing ring, then the mold is opened, at this time the upper die seat 1 with the steel sheet and the silica gel ring is separated from the middle die seat 3, then the limiting plate 62 is pulled out, then the middle die seat 3 is turned by rotating the alignment handle 53, so that the middle die seat 3 is turned over, then the limiting plate 62 is inserted into the connecting port 61 through the lower die seat 2 by aligning the plug-in interface 60, so that the rotation of the middle die seat 3 is limited, then the mold is closed again, so that the forming cavity 42 and the casting cavity 40 form a mold cavity of the lower half of the sealing ring, and the lower half of the steel sheet is formed into the lower half of the sealing ring, thereby forming a complete sealing ring.

[0033] The embodiments of the specific implementation are the preferred embodiments of the application, and are not limited to the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
