Description

Technical Field

[0001] The utility model relates to the technical field of grouting molding equipment, in particular to a pressing mechanism of a grouting machine. Background Art

[0002] After the mold for blank forming in a ceramic high-pressure grouting machine is closed, it is necessary to further maintain a certain mold closing pressure. The existing mold closing cylinders usually have a long stroke. To increase the mold closing pressure, it is necessary to increase the cylinder diameter of the mold closing cylinder. Using the existing hydraulic station will cause the action speed to slow down. The mold closing pressure of the existing single cylinder acting on the mold is too concentrated, which also puts higher requirements on the structural strength of the mold. If the mold closing pressure is increased by a single cylinder, not only the equipment is bulky but also the overall manufacturing cost is increased. Finally, it is difficult to further increase the mold closing pressure. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a pressing mechanism of a grouting machine in view of the above-mentioned technical deficiencies. By setting a pressing cylinder and cooperating with a sliding rod, the further pressing of the moving mold is realized, the pressure requirement for the large-stroke mold closing cylinder is reduced, and the problem that the mold closing pressure of the existing grouting machine is difficult to further increase is solved.

[0004] To solve the above technical problem, the technical scheme adopted by the utility model is: a pressing mechanism of a grouting machine, including a frame and a pressing cylinder. A pressing rod axially extends from the bottom of the pressing cylinder. The top of the pressing cylinder is fixed in a sliding seat. Tracks are arranged on both sides of the sliding seat. The sliding seat is slidably connected along the tracks. One end of the tracks is provided with a pressing position. A through hole is arranged in the pressing position. A sliding rod is inserted into the through hole. The bottom end of the sliding rod is connected with the moving mold of the grouting machine. The axis of the sliding rod is arranged in the moving path of the pressing rod along the tracks.

[0005] Further optimizing the technical scheme, through holes are arranged at the upper and lower ends of the pressing position. A limiting plate is arranged at the top of the pressing position. The limiting plate is fixedly connected with the frame and is arranged on the upper part of the sliding seat away from the pressing cylinder.

[0006] Further optimizing the technical scheme, rollers are arranged on both sides of the bottom of the sliding seat. The rollers are rotatably connected to the upper part of the tracks. The sliding seat is arranged between the tracks and the limiting plate.

[0007] Further optimizing the technical scheme, a conversion telescopic cylinder is arranged at one end of the sliding seat. The end of the conversion rod extended by the conversion telescopic cylinder is hinged to the sliding seat. The extending direction of the conversion rod is the same as the sliding direction of the sliding seat.

[0008] Compared with the prior art, the utility model has the following advantages:

[0009] 1. By setting a pressing cylinder and cooperating with a sliding rod, the further pressing of the moving mold is realized, the pressure requirement for the large-stroke mold closing cylinder is reduced, and the mold closing pressure of the grouting machine is effectively increased;

[0010] 2. When the mold is opened, the conversion telescopic cylinder contracts, driving the slide seat and the pressing cylinder away from the pressing position, moving the moving mold upward to open the mold. The sliding rod slides in the through hole in the pressing position. The sliding rod not only guides the movement of the moving mold but also further presses the moving mold after mold clamping.

[0016] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the specific embodiments in conjunction with the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0017] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. involved in the present application document indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present disclosure. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0018] In combination with Figures 1 to 4As shown in the figure, a pressing mechanism of a grouting machine includes a frame 1 and a pressing cylinder 2. A pressing rod 21 axially extends from the bottom of the pressing cylinder 2. The top of the pressing cylinder 2 is fixed in a sliding seat 20. Tracks 22 are provided on both sides in the moving direction of the sliding seat 20. Roller wheels 201 are provided on both sides of the bottom of the sliding seat 20. The roller wheels 201 are in rolling connection with the upper part of the tracks 22. The sliding seat 20 is arranged between the tracks 22 and a limiting plate 11.

[0019] The sliding seat 20 is slidably connected along the tracks 22. A pressing position 23 is provided at one end of the tracks 22. A conversion telescopic cylinder 5 for driving the sliding seat 20 to move is provided at the other end of the tracks 22. The position conversion of the sliding seat 20 and the pressing cylinder 2 is realized by the provided conversion telescopic cylinder 5.

[0020] The end of a conversion rod 51 extended by the conversion telescopic cylinder 5 is hinged to the sliding seat 20. The extending direction of the conversion rod 51 is the same as the sliding direction of the sliding seat 20.

[0021] A through hole 231 is provided in the pressing position 23. A sliding rod 4 is inserted into the through hole 231. The bottom end of the sliding rod 4 is connected to a moving die 3 of the grouting machine. The axis of the sliding rod 4 is arranged in the moving path of the pressing rod 21 along the tracks 22. The through hole 231 is provided at the upper and lower ends of the pressing position 23. A limiting plate 11 is provided at the top of the pressing position 23. The limiting plate 11 is fixedly connected to the frame 1. The limiting plate 11 is arranged on the upper part of the sliding seat 20 away from the pressing cylinder 2.

[0022] During use, in combination with Figures 1 to 4 As shown in the figure, two groups of the above-mentioned pressing mechanisms are provided in the grouting machine. The bottom ends of two sliding rods 4 are respectively fixedly connected to the moving die 3 in the grouting machine. The moving direction of the moving die 3 is the same as the length direction of the sliding rods 4. After the moving die 3 is closed, the top end of the sliding rod 4 moves to the lower side of the pressing position 23. When the pressing cylinder 2 is in a contracted state, it drives the conversion rod 51 of the conversion telescopic cylinder 5 to extend. The sliding seat 20 drives the pressing cylinder 2 to move to the pressing position 23. When the pressing rod 21 is aligned with the sliding rod 4, control the pressing rod 21 to extend downward. The pressing force of the pressing cylinder 2 presses the bottom moving die 3 through the corresponding sliding rod 4. When opening the die, first control the pressing cylinder 2 to contract, then control the conversion telescopic cylinder 5 to contract, drive the sliding seat 20 and the pressing cylinder 2 away from the pressing position 23, and move the moving die 3 upward to open the die. The sliding rod 4 slides in the through hole 231 in the pressing position 23. The sliding rod 4 not only has a guiding effect on the movement of the moving die 3, but also can further press the moving die 3 after closing.
