[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A hydraulic roller type mold lifter includes a frame, with multiple evenly distributed hydraulic cylinders installed at the bottom of the frame, and multiple evenly distributed rollers rotatably installed inside the frame. Mounting grooves that cooperate with the rollers are provided on both side walls of the frame. Limiting blocks for restricting the position of the rollers are slidably installed inside the mounting grooves. The limiting blocks and the frame are connected to each other via connecting studs.

[0007] Preferably, the side wall of the frame is provided with a first threaded hole that mates with the connecting stud.

[0008] Preferably, the bottom of the mounting groove is arc-shaped.

[0009] Preferably, the limiting block includes a first block with an arc-shaped concave bottom, and a pad is installed in the concave part.

[0010] Preferably, a second block with a thickness smaller than that of the first block is fixedly installed on both sides of the first block.

[0011] Preferably, the second block has a second threaded hole that mates with the connecting stud.

[0012] Preferably, the roller includes a mounting shaft that is mounted on the frame via a connecting stud.

[0013] Preferably, both ends of the mounting shaft are connected to limiting pieces located on the outside of the frame.

[0014] Preferably, the diameter of the limiting piece is greater than the width of the mounting groove.

[0015] Preferably, a support wheel located inside the frame is rotatably mounted on the outer side of the mounting shaft.

[0016] The beneficial technical effects of this utility model are as follows: According to the hydraulic roller type mold lifter of this utility model, the roller can be easily disassembled and replaced during use by setting the limiting block, connecting stud and mounting groove. When disassembling, simply unscrew the connecting stud to remove the limiting block from the inside of the mounting groove to release the limiting of the roller. At this time, the roller can be taken out from the inside of the mounting groove. Attached Figure Description

[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figures 1-6As shown, the hydraulic roller type mold lifter provided in this embodiment includes a frame 1. Multiple evenly distributed hydraulic cylinders 5 are installed at the bottom of the frame 1. Multiple evenly distributed rollers 2 are rotatably installed inside the frame 1. Mounting grooves 6 that cooperate with the rollers 2 are opened on both side walls of the frame 1. Limiting blocks 3 for limiting the position of the rollers 2 are slidably installed inside the mounting grooves 6. The limiting blocks 3 and the frame 1 are connected to each other by connecting studs 4. Through the setting of the limiting blocks 3, connecting studs 4 and mounting grooves 6, the rollers 2 can be easily disassembled and replaced during use. When disassembling, simply unscrew the connecting studs 4 to remove the limiting blocks 3 from the inside of the mounting grooves 6 to release the limitation on the rollers 2. At this time, the rollers 2 can be removed from the inside of the mounting grooves 6.

[0026] In an optional embodiment, the side wall of the frame 1 has a first screw hole 7 that mates with the connecting stud 4. The bottom of the mounting groove 6 is arc-shaped. The limiting block 3 includes a first block with an arc-shaped concave bottom, a pad 8 installed in the concave part, and a second block with a thickness less than itself fixedly installed on both sides of the first block. The second block has a second screw hole 9 that mates with the connecting stud 4. It should be noted that the mounting groove 6 facilitates the installation of the roller 2, the first block facilitates the compression and limiting of the roller 2, the first screw hole 7 and the second screw hole 9 facilitate the use with the connecting stud 4, and the pad 8 is placed between the mounting shaft 201 and the first block.

[0027] In an optional embodiment, the roller 2 includes a mounting shaft 201 that is mounted on the frame 1 via a connecting stud 4. Both ends of the mounting shaft 201 are connected to limiting plates 203 located on the outer side of the frame 1. The diameter of the limiting plates 203 is larger than the width of the mounting groove 6. A support wheel 202 located on the inner side of the frame 1 is rotatably mounted on the outer side of the mounting shaft 201. It should be noted that the limiting plates 203 prevent the mounting shaft 201 from dislodging from the mounting groove 6, and facilitate the installation of the support wheel 202.

[0028] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
