[0021] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific embodiments of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solutions claimed in the present invention.

[0022] like Figure 1-6 An automatic mold-flipping device includes a connecting frame 1, a first template 2, a second template 3, a moving device, a first lifting structure 4, and a second lifting structure 5. The first template 2 is located above the second template 3. The second lifting structure 5 includes a second side frame 51. The connecting frame 1 is disposed on the back of the second template 3 and between the second template 3 and the second side frame 51. The second template 3 can be connected to the second side frame 51 via the connecting frame 1.

[0023] The first lifting structure 4 includes a first side frame 41 and a first lifting assembly 42. The first side frame 41 is connected to the first lifting assembly 42. An installation groove 7 is formed at the end of the first side frame 41 near the second side frame 51. The upper end of the connecting frame 1 extends into the installation groove 7. The moving device is disposed in the installation groove 7 and is used to push the connecting frame 1 and the second template 3 toward the first lifting assembly 42 to connect the connecting frame 1 to the first lifting assembly 42. The first lifting assembly 42 is used to adjust the height position of the connecting frame 1 and the second template 3.

[0024] This invention proposes an automatic mold-flipping device. The second template 3 is connected to the second side frame 51 through the connecting frame 1. Under the action of the moving device, the connecting frame 1, the second template 3, and the second side frame 51 are pushed to move closer to the first lifting component 42, so as to connect the connecting frame 1, the second template 3, and the second side frame 51 to the first lifting component 42. The first lifting component 42 drives the connecting frame 1, the second template 3, and the second side frame 51 to move upward, thereby driving the second template 3 to rise and move above the first template 2, thus realizing the mold flipping.

[0025] A connecting cylinder 11 is provided on the connecting frame 1. The connecting cylinder 11 extends toward the second side frame 51 and has a connecting hole 111 at the extended end. A positioning cylinder 510 is also provided on the second side frame 51. The positioning cylinder 510 extends and connects to the connecting hole 111 to connect the connecting frame 1 and the second side frame 51 together. The connecting cylinder 11 can drive the second side frame 51 and the second lifting assembly 52 to move horizontally.

[0026] The second side frame 51 and the second lifting assembly 52 are fixedly connected; the first side frame 41 and the first lifting assembly 42 are fixedly connected.

[0027] In this embodiment, the positioning cylinder 510 is fixedly mounted on the second side frame 51. When the positioning cylinder 510 is connected to the connecting hole 111, the second side frame 51 is connected to the connecting frame 1. At this time, the extension and retraction of the connecting cylinder 11 can drive the second side frame 51 to move left and right in the horizontal position. Since the second side frame 51 is connected to the second lifting assembly 52, the second side frame and the second lifting assembly 52 are driven to move left and right together in the horizontal position.

[0028] In this embodiment, the second side frame 51 includes a second left side frame 511 and a second right side frame 512. A second mounting space 513 is formed between the second left side frame 511 and the second right side frame 512. The connecting frame 1 is disposed in the second mounting space 513. When the positioning cylinder 510 is connected to the connecting hole 111, it drives the second left side frame 511 and the second right side frame 512 to move closer to each other. That is, the second left side frame 511 moves to the right, and the second right side frame 512 moves to the left.

[0029] Furthermore, in this embodiment, the lateral width between the second installation spaces 513 is greater than the lateral width of the connecting frame 1.

[0030] In this embodiment, the second lifting assembly 52 includes a second left lifting assembly 521 and a second right lifting assembly 522. The second left side frame 511 is connected to the second left lifting assembly 521, and the second right side frame 512 is connected to the second right lifting assembly 522. When the second left side frame 511 moves to the right and the second right side frame 512 moves to the left, the second left lifting assembly 521 moves to the right and the second right lifting assembly 522 moves to the left.

[0031] In this embodiment, the first lifting structure 4 further includes a first lifting component 42, and the first side frame 41 is above the second side frame 51, the first lifting component 42 is above the second lifting component 52, and the structure of the first side frame 41 is consistent with that of the second side frame 51, and the structure of the first lifting component 42 is consistent with that of the second lifting component 52.

[0032] In this embodiment, the first side frame 41 includes a first left side frame 411 and a first right side frame 412; the first lifting assembly 42 includes a first left lifting assembly 421 and a first right lifting assembly 422; the first left side frame 411 is above the second left side frame 511, the first right side frame 412 is above the second right side frame 512, the first left lifting assembly 421 is above the second left lifting assembly 521, and the first right lifting assembly 422 is above the second right lifting assembly 522.

[0033] When the connecting cylinder 11 drives the second side frame 51 and the second lifting assembly 52 to move closer to each other, the second side frame 51 moves from a position below the first side frame 41 to a position offset from the first side frame 41. That is, the second left side frame 511 moves to the lower right end of the first left side frame 411, and the second right side frame 512 moves to the lower left end of the first right side frame 412. This prepares for the subsequent upward movement of the second side frame and the second lifting assembly 52, and avoids the second side frame and the second lifting assembly 52 colliding with the first side plate and the first lifting assembly 42 during the upward movement.

[0034] The moving device includes a push cylinder 6, which includes a push cylinder 6 body and a push rod. One end of the push rod is connected to the push cylinder 6 body, and the other end forms a push surface. The push surface cooperates with the connecting frame 1 to push the connecting frame 1 to move closer to the second lifting assembly 52.

[0035] The first lifting assembly 42 includes a first lifting cylinder and a lifting bar. One end of the lifting bar is connected to the first lifting cylinder, and the other end extends downward to form a support platform 420 at the lower end. When the connecting frame 1 moves toward the second lifting assembly 52, the connecting frame 1 moves onto the support platform 420.

[0036] A demolding cylinder 13 is provided on the connecting frame 1, and a demolding box is provided on the first template 2. A demolding module is provided on the demolding box, and the demolding cylinder 13 can extend towards the demolding box and act on the demolding module. The demolding module can extend outward or retract inward into the demolding box. The demolding cylinder 13 is positioned correspondingly to the demolding box. When the demolding cylinder 13 extends, it acts on the demolding module of the demolding box to push the demolding box outward, thereby pushing the first template 2 and the casting body to separate.

[0037] A mold-gripping plug 12 is provided on the connecting frame 1, and a mold-gripping groove is provided on the first template 2. The mold-gripping plug 12 extends into the mold-gripping groove to connect the connecting frame 1 and the first template 2. The connection between the connecting frame 1 and the first template 2 is achieved through the mold-gripping plug 12 engaging with the mold-gripping groove.

[0038] In this embodiment, the connecting frame 1 includes a first truss 14 and a second truss 15, with the first truss 14 above the second truss 15. The first truss 14 and the second truss 15 are arranged laterally in the horizontal direction. The connecting cylinders 11 are respectively disposed on the first truss 14 and the second truss 15, extending outward from the first truss 14 and the second truss 15. The demolding cylinder 13 is disposed on the first truss 14 and the second truss 15, arranged in the front-back direction, extending forward from the first truss 14 and the second truss 15. A connecting truss is provided between the first truss 14 and the second truss 15, and a mold-gripping plug 12 is provided on the connecting truss. A first extension truss 16 and a second extension truss 17 are provided at the first truss 14. The first extension truss 16 extends upward and to the left from the first truss 14 and extends into the mounting groove 7 at the first left side frame 411. The second extension truss 17 extends upward and to the right from the first truss 14 and extends into the mounting groove 7 at the first right side frame 412.

[0039] In this embodiment, the first side frame 41 and the second side frame 51 have the same structure, that is, both the first side frame 41 and the second side frame 51 are provided with connecting holes 111, and both the first side frame 41 and the second side frame 51 are provided with mounting grooves 7 and ejection cylinders 6 at their bottoms. The first lifting assembly 42 has the same structure as the second lifting assembly 52.

[0040] After the second template 3 rises above the first template 2, the second side frame is pushed outward by the connecting cylinder 11 to reset it, so that the second side frame is positioned above the first side plate. At this time, the positioning cylinder 510 on the second side frame retracts, disengaging the positioning cylinder 510 from the connecting hole 111 and the connection between the connecting frame 1 and the second side frame. Then, the mold-grabbing plug 12 disengages from its connection with the mold-grabbing groove, disengaging the connection between the connecting frame 1 and the second template 3. The connecting frame 1 moves downward under gravity. When the first extension truss 16 and the second extension truss 17 of the connecting frame 1 fall into the mounting groove 7 of the first side frame 41, the connecting frame 1 stops moving downward. The first template 2 can be moved upward above the second template 3 by the connection and movement of the connecting frame 1 with the first template 2 and the first side frame 41, realizing continuous mold flipping operation.

[0041] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
