Description

Technical Field

[0001] This utility model relates to the field of press manufacturing, and in particular to a quick-release, highly stable structure for press molds. Background Technology

[0002] Traditional press mold installation structures commonly suffer from low assembly and disassembly efficiency and insufficient stability. On the one hand, traditional mold installation often relies on bolt fastening, requiring the loosening and tightening of numerous bolts one by one when changing molds. This cumbersome and time-consuming operation, especially in production scenarios with frequent mold changes, severely impacts equipment utilization. On the other hand, the connection structure often depends on a single fastening method. During press operation, external forces such as vibration and impact can easily cause the mold to loosen or shift, leading to a decrease in mold positional accuracy. This not only affects product processing quality but may also cause equipment failure or even safety accidents. Utility Model Content

[0003] The purpose of this invention is to provide a quick-release, highly stable structure for press molds that is easy to install and has higher structural stability.

[0004] The purpose of this utility model is achieved as follows: A quick-release, high-stability structure for a press mold includes a mold fixing seat and a drive shaft connected to the mold fixing seat. The mold fixing seat has outer fixing holes around its perimeter and an inner fixing hole in the center. A bolt fixing hole is provided on one side of the inner fixing hole. Raised rails are provided on both sides of the inner fixing hole, and the raised rails are connected to a limiting seat. An insertion channel is provided on the side of the limiting seat. A limiting plate is provided on the top of the limiting seat. The limiting plate has a V-shaped structure. One open end of the limiting plate is hinged to the limiting seat via a rotating shaft, and the other open end has a first fixing hole. A second fixing hole is provided at the bottom of the limiting plate. The second fixing hole is connected to the bolt fixing hole on the mold fixing seat via a bolt, and the first fixing hole is connected and fixed to the limiting seat via a bolt.

[0005] Preferably, the bottom of the drive shaft is connected to a fixing post, the fixing post being a first post and a second post connected together, and the insertion channel being composed of a first channel and a second channel, the first channel being in a limiting fit with the first post, and the second channel being in a limiting fit with the second post.

[0006] Preferably, the bottom inner side of the limiting plate is provided with an arc-shaped contact surface, which abuts against the first column.

[0007] Preferably, the first column, the second column, and the arc-shaped contact surface are all covered with a rubber layer.

[0008] Preferably, the inner side of the insertion channel is a semi-circular contact surface adapted to the first column.

[0009] Preferably, the height of the first column is greater than the height of the first channel, and the main body of the limiting plate is placed in the gap between the bottom of the drive shaft and the limiting seat.

[0010] Preferably, the raised track has a T-shaped cross-section, and the limiting seat has a T-shaped groove that slides with the raised track. One end of the T-shaped groove is open, and the other end is closed.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] 1. Through the sliding fit of the T-slot and the raised track, as well as the quick insertion and removal design of the fixed column and the insertion channel, the mold can be quickly installed and disassembled, which greatly shortens the mold change time and improves the production efficiency of the press compared with the traditional structure.

[0013] 2. The limiting plate can effectively limit the position of the fixed column, maintaining the mold position accuracy even under high-speed and high-pressure operation of the press, reducing vibration and shaking, ensuring product processing quality, and reducing scrap rate; at the same time, the limiting plate can also fix the limiting seat, which only requires two bolts, which is convenient and quick.

[0024] like Figure 1-6 As shown, a quick-release, high-stability structure for a press mold includes a mold fixing base 1 and a drive shaft 2 connected to the mold fixing base 1. The mold fixing base 1 has an outer fixing hole 101 around its perimeter and an inner fixing hole 102 in the middle. A bolt fixing hole 103 is provided on one side of the inner fixing hole 102. Raised rails 104 are provided on both sides of the inner fixing hole 102 and are connected to a limiting seat 3. An insertion channel 301 is provided on the side of the limiting seat 3. A limiting plate 4 is provided on the top of the limiting seat 3. The limiting plate 4 has a V-shaped structure. One open end of the limiting plate 4 is hinged to the limiting seat 3 through a rotating shaft, and the other open end has a first fixing hole 401. A second fixing hole 402 is provided at the bottom of the limiting plate 4. The second fixing hole 402 is connected to the bolt fixing hole 103 on the mold fixing base 1 through a bolt. The first fixing hole 401 is connected and fixed to the limiting seat 3 through a bolt.

[0025] like Figure 1 , 2As shown in Figure 5, a fixed post 5 is connected to the bottom of the drive shaft 2. The fixed post 5 is a connection between the first post 501 and the second post 502. The insertion channel 301 is composed of the first channel 3011 and the second channel 3012. The first channel 3011 is in a limiting fit with the first post 501, and the second channel 3012 is in a limiting fit with the second post 502. The fixed post and the drive shaft are connected by a thread, which is convenient for later maintenance and replacement.

[0026] like Figure 1 , 2 As shown in Figure 4, the bottom inner side of the limiting plate 4 is provided with an arc-shaped contact surface 403, which abuts against the first column 501. The good fit of the arc structure further restricts the displacement of the fixed column and enhances the stability of the mold connection. When the press is running, it can effectively prevent loosening or shaking between the drive shaft and the mold fixed seat, ensure the positional accuracy of the mold during the working process, and improve the product processing quality.

[0027] like Figure 4-5 As shown, the first column 501, the second column 502, and the arc-shaped contact surface 403 are all covered with a rubber layer (not shown in the figure). The rubber layer can reduce rigid wear between components and extend the service life of each component.

[0028] like Figure 6 As shown, the inner side of the insertion channel 301 is a semi-circular contact surface 3013 that is adapted to the first column 501, which can effectively limit the movement of the first column and ensure the stability after mating.

[0029] like Figure 1-2 As shown, the height of the first column 501 is greater than the height of the first channel 3011. The main body of the limiting plate 4 is placed in the gap between the bottom of the drive shaft 2 and the limiting seat 3, ensuring that the arc-shaped contact surface on the limiting plate can contact the first column.

[0030] like Figure 1 , 2 As shown in Figure 3, the raised track 104 has a T-shaped cross section. The limiting seat 3 has a T-shaped groove 302 that slides with the raised track 104. One end of the T-shaped groove 302 is open and the other end is closed. The open end facilitates the installation and disassembly of the limiting seat, while the closed end prevents the limiting seat from sliding off the track during the sliding process, ensuring that the limiting seat slides stably on the track and guaranteeing the safety and stability of the mold installation and disassembly process.

[0031] The working principle of this utility model is explained as follows: When this quick-release, high-stability structure for press molds is in operation, the mold fixing seat is first installed on the mold fixing base through the outer and inner fixing holes. During installation, the limiting seat is slid into the appropriate position along the T-slot of the raised track. The fixing post at the bottom of the drive shaft is aligned with the insertion channel of the limiting seat. Due to the limiting fit between the first and second posts and the first and second channels, the fixing post can be quickly and accurately inserted. Then, the limiting plate is rotated so that it is bolted to the bolt fixing hole of the mold fixing base through the second fixing hole. The first fixing hole is connected to the limiting seat. At this time, the arc-shaped contact surface at the bottom of the limiting plate is in close contact with the first post, and the limiting plate is further fixed through the bolt fixing hole. For disassembly, the bolts of the limiting plate are loosened, it is opened around the rotating shaft, and then slid out of the limiting seat along the raised track, thus quickly completing the mold disassembly and achieving efficient and stable mold assembly and disassembly operations.
