Technical Field

[0001] The invention relates to the technical field of daily-use ceramic processing, in particular to an automatic mold opening structure of a daily-use ceramic rolling forming line. Background Art

[0002] The daily-use ceramic rolling forming line requires a plaster mold for production and processing. In the daily-use ceramic rolling forming equipment, products that are small on the top and large on the bottom (reverse cone and arc shape, etc.) cannot be produced in ordinary molding production lines. Traditionally, most of them use single-machine equipment, which requires manual mold opening to take out the internal mud blanks, making the mold opening method inefficient. For this reason, we provide an automatic mold opening structure for the daily-use ceramic rolling forming line. Summary of the invention

[0022] The correction mechanism 100 also includes a servo motor 6, there are two servo motors 6 and they are respectively installed on the left and right sides of the bottom of the adjustment plate 3, a planetary reducer 7 is fixedly connected to the top of the adjustment plate 3 and the position corresponding to the servo motor 6, the top end of the output shaft of the servo motor 6 passes through the adjustment plate 3 and is fixedly connected to the rotating shaft of the planetary reducer 7, the top end of the output shaft of the planetary reducer 7 is fixedly connected to the bottom of the mold barrel 4, the bottom of the first cylinder 1 is fixedly connected to a first mounting seat 8, a support seat 9 is arranged above the mold barrel 4, and two photoelectric switches 10 are fixedly connected to the bottom of the support seat 9.

[0023] The gypsum mold 5 consists of a mold bottom 51, two inner molds 52 and an outer mold 53. The mold bottom 51 is arranged on the inner walls of the two inner molds 52, and the two inner molds 52 are arranged on the inner walls of the outer mold 53. A positioning notch 54 is opened on the inner mold 52 located on the front side, and a mold line 55 is formed in the gap where the two inner molds 52 contact each other.

[0024] The second cylinder 2 is arranged on the right side of the first cylinder 1, and a movable moving plate 21 is fixedly connected to the top of the second cylinder 2, and linear bearings 22 are fixedly connected to the left and right sides of the top of the moving plate 21, and the bottom end of the linear bearing 22 penetrates the moving plate 21 and extends to the outside thereof, and a second mounting seat 23 is fixedly connected to the bottom of the second cylinder 2, and a guide shaft 24 is fixedly connected to the top of the second mounting seat 23 and at a position corresponding to the linear bearing 22, and the top end of the guide shaft 24 penetrates the linear bearing 22 and extends to the inside thereof and slides in contact with the inner wall of the linear bearing 22, and a push rod 25 is fixedly connected to the top of the linear bearing 22.

[0025] Furthermore, two electric push rods 31 are installed at the bottom of the support seat 9 and corresponding to the position of the push rod 25. An adjusting block 32 is installed at the bottom end of the electric push rod 31, and a blocking rod 26 is installed at the bottom of the adjusting block 32.

[0031] When in use, the automatic line tray drives the gypsum mold 5 to move from left to right (the automatic line tray is a movable fixture, and the automatic line tray is an existing public technology, so no more elaboration is made here), the gypsum mold 5 moves to the top of the mold barrel 4, the first cylinder 1 rises, the mold barrel 4 holds up the gypsum mold 5, and then the photoelectric switch 10 detects the position of the positioning notch 54, and then the servo motor 6 is started. The servo motor 6 drives the mold barrel 4 and the gypsum mold 5 to rotate through the planetary reducer 7, so as to adjust the position of the mold line 55. After the adjustment is completed, the first cylinder 1 descends, so that the mold barrel 4 is separated from the gypsum mold 5;

[0032] The automatic line tray drives the plaster mold 5 to move rightward, moves the plaster mold 5 to the position of the ejector 25, and is located at the position of the mold opening mechanism 200. At this time, the ejector 25 and the mold line 55 have been corrected to be parallel. The state of the mold line 55 and the ejector 25 is as follows: Figure 5 As shown, the electric push rod 31 is started, the electric push rod 31 drives the adjustment block 32 to move downward, the adjustment block 32 drives the stop rod 26 to move downward, so that the stop rod 26 presses the outer mold 53 of the gypsum mold 5, the second cylinder 2 is started, the second cylinder 2 drives the moving plate 21 and the linear bearing 22 to move upward, the linear bearing 22 drives the push rod 25 to move upward, the push rod 25 lifts the inner mold 52 and the mold bottom 51, and the two halves of the inner mold 52 are separated to both sides under the action of gravity, completing the mold opening action, and realizing the following Figure 6 The status shown;
