Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0023] Example: like Figure 1-4 As shown in the figure, this application discloses a mandrel driving device for realizing the up and down movement of the lower mandrel, thereby facilitating the ejection of the finished product from the mold.

[0024] like Figure 1-3 As shown, the specific structure of this application includes: The lower support plate 1 is a square support plate with mounting holes to facilitate the subsequent installation of the column. After assembly, it is installed on the frame to realize the function of material feeding. The column 2 is vertically installed on the lower support plate 1. The column 2 is an existing column, mainly used for installation support, so that there is enough space to install components such as the mandrel. The upper support plate 3 is installed on the top of the column 2. The upper support plate 3 can be composed of two plates connected together. It is installed on other components for connection, thereby ensuring stability. The lower mandrel assembly 4 is movably mounted on the lower support plate 1. The lower mandrel assembly 4 includes a mandrel for subsequent material ejection. At the same time, the lower mandrel assembly 4 can move up and down to complete the material ejection action of the mandrel. The drive assembly 5 is mounted on the lower support plate 1 and is configured to push the lower mandrel assembly 4 to reciprocate in the vertical direction. Specifically, the drive assembly 5 moves in the horizontal direction and can be converted into the vertical movement of the lower mandrel assembly 4 by the cooperation of the internal components of the drive assembly 5 and the internal components of the lower mandrel assembly 4.

[0025] To achieve stable movement of the lower mandrel assembly 4, this application designs the lower mandrel assembly 4, which includes: The movable column 401 is installed on the lower support plate 1 and can move vertically. The cooperation between the movable column 401 and the lower support plate 1 is the existing method, which only needs to ensure that the movable column 401 can move vertically stably. The movable shaft 402 is installed at the bottom of the movable column 401. Specifically, the bottom of the movable column 401 is provided with a groove, and the movable shaft 402 is horizontally assembled and perpendicular to the movable column 401. The driving component 5 includes: The lower connecting plate 501 is vertically installed on the outside of the lower support plate 1, and the lower connecting plate 501 is provided with a sliding groove 502 that cooperates with the movable shaft 402; The driving component 503 is horizontally mounted on the outside of the lower connecting plate 501. The driving component 503 can be an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder. A movable plate 504 is installed at the output end of the drive component 503, and a push groove 505 is provided on the movable plate 504. The push groove 505 cooperates with the movable shaft 402. The movable plate 504 has an L-shaped structure. When the driving component 503 pushes the movable plate 504 to reciprocate in the horizontal direction, it pushes the movable column 401 to move in the vertical direction through the pushing groove 505.

[0026] The drive assembly 5 in this application is further described. The drive member 503 pushes horizontally, thereby pushing the movable plate 504 to move horizontally. The movable shaft 402 is located inside the push groove 505. At this time, the movable plate 504 pushes the movable shaft 402 to move up and down. The movable shaft 402 is in the sliding groove 502, which is an oblong hole, so as to provide a path for the movable shaft 402 to move up and down.

[0027] In order to ensure the stability of the movement of the movable shaft 402, this application needs to limit the two ends of the movable shaft 402 so that it can move up and down stably. Therefore, there are two lower connecting plates 501 in this application, and the lower connecting plates 501 are arranged in parallel and spaced apart. This way, there can be enough gap between the two to facilitate the placement of the subsequent movable shaft 402 and to facilitate the stable up and down movement of the two ends of the movable shaft 402. The bottom of the movable column 401 is located between the two lower connecting plates 501. Part of the movable shaft 402 is located above the lower support plate 1, and another part is located below the lower support plate 1. The movable shaft 402 is installed on the part below the lower support plate 1. When the two ends of the movable shaft 402 move up and down along the sliding groove 502, it can push the movable column 401 to move up and down.

[0028] In order to convert the horizontal movement of the movable plate 504 into the vertical movement of the movable column 401, this application designs a pushing groove 505, specifically, the pushing groove 505 includes: First inclined segment 506; The second inclined segment 507 is connected to the first inclined segment 506; The first inclined segment 506 and the second inclined segment 507 form a continuous profile of the push groove 505 to guide the movement of the movable shaft 402. Since the push groove 505 is inclined, when the push groove 505 moves horizontally with the movable plate 504, there is a vertical displacement variable. The movable shaft 402 is in the push groove 505, and at this time the movable shaft 402 also has a vertical displacement. Finally, it drives the movable column 401 to move up and down.

[0029] Meanwhile, the two inclined sections in this application have different inclination angles. The inclination angles of the first inclined section 506 and the second inclined section 507 are different, so the displacement rate of the vertical displacement variable of the push groove 505 is different, which can ultimately change the lifting rate of the movable column 401.

[0030] Preferably, for the stability of the structure of this application, there are two columns 2, and the columns 2 are installed at intervals on the lower support plate 1; One end of the lower support plate 1 is provided with a groove 101, and an opening and closing component 6 is installed in the groove 101. The opening and closing component 6 cooperates with any one of the columns 2, and the remaining column 2 is connected to the lower support plate 1 through a bearing. The opening and closing component 6 in this application can lock the column 2, thereby ensuring the stability of the overall structure. After the opening and closing component 6 is opened, the entire lower support plate 1 can rotate around the other column 2, thereby allowing the components connected to the lower support plate 1 to rotate to the outside, which is convenient for subsequent maintenance.

[0031] The opening and closing component 6 can be an existing part, and its specific structure includes: The movable block 601 is hinged at one end to the groove 101 to clamp or release the column 2. Specifically, the movable block 601 is provided with a hinge on its outer side, which enables the rotation of the lower support plate 1 and the movable block 601. The locking component 602 is connected at one end to the lower support plate 1 and at the other end to the movable block 601; specifically, the locking component 602 is a locking handle, which locks with the locking plate on the movable block 601.

[0032] To ensure the stability of the corresponding component structure in the lower mandrel assembly 4, the lower mandrel assembly 4 described in this application further includes: Support plate 403 is installed on the top of the movable column 401; Mounting base 404 is disposed on the support plate 403 for mounting subsequent lower mandrels; The lower core rod 406 is disposed on the mounting base 404.

[0033] Specifically, the mounting base 404 is provided with a mounting groove 405, and the lower core rod 406 is movably disposed inside the mounting groove 405; in this application, the mounting groove 405 is located on the outside of the mounting base 404, and at this time, the bottom of the lower core rod 406 can be inserted into the mounting groove 405, thereby ensuring the stability of the entire structure.

[0034] The working process of this application: First, insert the lower mandrel 406 into the mounting slot 405, lock the opening and closing assembly 6, then start the drive assembly 5 to push the movable plate 504 to move horizontally. At this time, the push slot 505 pushes the movable shaft 402 to move up and down, which in turn drives the movable column 401 to move up and down, finally realizing the up and down movement of the lower mandrel 406.
