DETAILED DESCRIPTION

[0032] The core of the utility model is to disclose an active mold adjusting device to improve the movement stability of the active mold adjusting device and reduce the difficulty of replacing the active mold.

[0033] In order to make the technical personnel in this field better understand the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the utility model described in the claims.

[0034] like Figure 1 As shown, the flexible mold adjustment device provided by the embodiment of the utility model comprises a flexible mold rod 10, an opening and closing mechanism 30 and a connecting flange 40, wherein the flexible mold rod 10 is directly connected to the cylinder rod 210 of the oil cylinder 20, so that the oil cylinder 20 can directly drive the flexible mold rod 10 to avoid the instability existing in indirect driving, and the opening and closing mechanism 30 is sleeved on the outer wall of the flexible mold rod 10, and at the same time, in the circumferential direction of the flexible mold rod 10, the opening and closing mechanism 30 and the flexible mold rod 10 are locked and matched. It should be noted that, here specifically refers to that the flexible mold rod 10 can withstand the torque of the opening and closing mechanism 30 in the circumferential direction of the flexible mold rod 10, so as to apply a rotational action to the flexible mold rod 10 through the opening and closing mechanism 30, which can be realized by slot hole matching, welding or clamping, and the connecting flange 40 is used to connect the mold and the flexible mold rod 10, specifically, its opposite sides are respectively connected to the mold and the flexible mold rod 10. The mold rod 10 is connected, and one end of the active mold rod 10 is embedded in the connecting flange 40 and is locked with the inner wall of the connecting flange 40, so that the active mold rod 10 can drive the connecting flange 40 and the mold on the other side to move, and the locking connection between the active mold rod 10 and the connecting flange 40 here can be achieved by the interference fit of the inner wall. At the same time, when the active mold rod 10 is rotated by a first angle along its circumferential direction, the locking fit between the active mold rod 10 and the connecting flange 40 is unlocked, so that the mold can move independently for replacement and other operations. In the above-mentioned active mold adjustment device, since the active mold rod 10 is directly driven by the cylinder rod 210, the movement process of the active mold rod 10 is more stable. At the same time, the active mold rod 10 and the connecting flange 40 are locked and unlocked by rotation, which reduces the connecting components and improves the convenience of unlocking the active mold rod 10 and the connecting flange 40.

[0035] The flexible mold adjustment device provided by the embodiment of the utility model directly connects the flexible mold rod 10 with the cylinder rod 210 of the oil cylinder 20, so that the cylinder rod 210 can directly drive the flexible mold rod 10 to ensure the stability of the driving. At the same time, one end of the flexible mold rod 10 is locked and connected to the inner wall of the connecting flange 40 to drive the connecting flange 40 and the mold on the other side to move. The locking connection is set to abut interference fit, so that the flexible mold rod 10 can be unlocked from the connecting flange 40 when it rotates along its circumferential direction by a first angle, so that the replacement of the mold and the connecting flange 40 is convenient and efficient, and the rotation drive of the flexible mold rod 10 is performed by the opening and closing mechanism 30, which is sleeved on the outer wall of the flexible mold rod 10 and locked with the flexible mold rod 10 in the circumferential direction of the flexible mold rod 10. The operator can realize the rotation of the flexible mold rod 10 by driving the opening and closing mechanism 30, and then conveniently perform the locking and unlocking actions of the flexible mold rod 10 and the connecting flange 40.

[0036] Furthermore, if Figure 2-5 As shown, in a preferred embodiment of the present invention, one end of the active mold rod 10 that cooperates with the connecting flange 40 has an alternating concave and convex structure in the circumferential direction, and correspondingly, the inner wall of the connecting flange 40 also has an alternating concave and convex structure. When one end of the active mold rod 10 is embedded in the connecting flange 40 and installed, when the raised portion 110 on the active mold rod 10 is butted against the raised portion 110 on the connecting flange 40, the active mold rod 10 and the connecting flange 40 are in contact due to the interference fit of the two raised portions 110. The flange 40 is locked, and the active mold rod 10 can move synchronously with the connecting flange 40. When the active mold rod 10 rotates a certain angle in the circumferential direction, the raised portion 110 on the active mold rod 10 rotates to a position corresponding to the recessed portion 410 on the connecting flange 40. At this time, the raised portion 110 on the active mold rod 10 and the recessed portion 410 on the connecting flange 40 are loosely matched, and the active mold rod 10 and the connecting flange 40 are unlocked, so that the connecting flange 40 can move independently.

[0037] Further, on the basis of the above embodiment, it is preferred that six protrusions 110 are evenly arranged on the outer wall of the flexible mold rod 10 in the circumferential direction. Here, the uniform arrangement of the six protrusions 110 means that the central angle corresponding to the area of ​​each protrusion 110 is the same, and the spacing between two adjacent protrusions 110 is equal to that of a single protrusion 110, that is, the flexible mold rod 10 is divided into twelve equal parts in the circumferential direction, and the central angle corresponding to each protrusion 110 is 30°, and the central angle corresponding to the area between two adjacent protrusions 110 is also 30°. Correspondingly, the wall surface of the connection flange 40 and the flexible mold rod 10 is also divided into twelve equal parts and the concave and convex parts are alternately arranged. At this time, the first angle is 30°.

[0038] It should be noted that the number of protrusions 110 on the flexible mold rod 10 can be designed to be other numbers. It is only necessary to design the connecting flange 40 to be a corresponding structure and select the corresponding first angle to achieve locking and unlocking of the flexible mold rod 10 and the connecting flange 40.

[0039] Furthermore, in a specific embodiment of the utility model, a fixing frame 50 is provided for stably supporting the oil cylinder 20. The fixing frame 50 is arranged on one side of the active mold rod 10 or around the active mold rod 10, and the fixing frame 50 is fixedly connected to the upper steam chamber by screws.

[0040] Furthermore, in a specific embodiment of the present invention, a guide groove is also provided on the outer wall of the active mold rod 10, and correspondingly, a guide rod extending into the guide groove is fixedly provided on the fixed frame 50, that is, the guide rod is a stable guide reference, and the guide groove is a recessed area on the active mold rod 10, which can be regarded as the active mold rod 10 itself as a guide structure, making it more stable during movement.

[0041] Furthermore, if Figure 2 and Figure 6 As shown, in a preferred embodiment of the utility model, key slots 60 are provided at the contact positions of the active mold rod 10 and the opening and closing mechanism 30, and the positions of the key slots 60 correspond to each other, so that the opening and closing mechanism 30 and the active mold rod 10 can achieve rotational locking cooperation through a key, so that the torque applied to the opening and closing mechanism 30 can be smoothly transmitted to the active mold rod 10 through the key.

[0042] It should be noted that the opening and closing mechanism 30 may be driven manually, by a motor, or by a combination of manual and motor drive.

[0043] In order to further optimize the above technical solution, Figure 1 and Figure 7 As shown, a limit switch 70 is also provided in the active mold adjustment device provided in the embodiment of the utility model. The limit switch 70 includes a bracket 710 and an upper limit portion 720 and a lower limit portion 730 arranged on the bracket 710, wherein the upper limit portion 720 and the lower limit portion 730 are arranged at intervals, and they can respectively move along the bracket 710 and lock at any position arranged on the bracket 710 to limit the upper and lower limit positions of the cylinder rod 210, thereby making the opening and closing positions of the active mold more precise, thereby protecting both the active mold and the cylinder 20 and increasing the service life of the active mold and the cylinder 20.

[0044] Further, on the basis of the above-mentioned embodiment, the limiting structure of the limit switch 70 for the cylinder rod 210 can be that the bracket 710 is provided with a groove between the upper limit portion 720 and the lower limit portion 730, and the cylinder rod 210 is fixedly provided with a limiting rod extending into the groove, when the limiting rod moves along the groove to the upper limit portion 720 and the lower limit portion 730, it will be blocked by the upper limit portion 720 and the lower limit portion 730 to be limited; and the limiting structure of the limit switch 70 for the cylinder rod 210 can also be that the upper limit portion 720 and the lower limit portion 730 are both position sensors, and the cylinder rod 210 is provided with an induction ring for detection by the position sensor, when the upper limit portion 720 and the lower limit portion 730 detect the induction ring, it means that the cylinder rod 210 moves to the position of the upper limit portion 720 or the lower limit portion 730, and then the feedback controller is used to stop the drive of the cylinder 20, thereby realizing the limiting requirement of the cylinder rod 210.

[0045] Furthermore, if Figure 1 and Figure 8 As shown, in a specific embodiment of the utility model, the flexible mold adjustment device also includes an oil receiving mechanism 80, and the oil receiving mechanism 80 specifically includes an oil receiving pot 810 and an oil receiving bracket 820.
