Description

Technical Field

[0001] This utility model relates to the technical field of single-column C-type hydraulic presses, and in particular to a single-column C-type hydraulic press that facilitates mold fixing. Background Technology

[0002] Single-column hydraulic presses are mainly suitable for processes such as stretching, forming and pressing of metal products. They can also process non-metallic materials, press powder metallurgy products, correct shaft parts, press sleeve parts, and shape and trim metal products.

[0003] When a single-column C-type hydraulic press extrudes and forms metal products, a corresponding mold needs to be installed on the press. Currently, most molds are installed and fixed with bolts, which is cumbersome and requires external tools for tightening and disassembling the bolts, making mold replacement very inconvenient. Therefore, this application proposes a single-column C-type hydraulic press that facilitates mold fixing. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a single-column C-type hydraulic press that facilitates mold fixing.

[0005] An embodiment of this utility model provides a single-column C-type hydraulic press for easy mold fixing, comprising:

[0006] A C-type mounting bracket is provided, on which a hydraulic cylinder is mounted, and a mounting rod is mounted on the output end of the hydraulic cylinder.

[0007] Mold assembly; the mold assembly includes a fixed mounting rod and a box-type mounting bracket on a C-shaped mounting bracket, with an upper mold slidably connected inside the upper box-type mounting bracket and a lower mold slidably connected inside the lower box-type mounting bracket;

[0008] The mold assembly includes two positioning rods that pass through and are slidably connected to a box-type mounting frame. Both the lower mold and the upper mold are provided with two positioning grooves. The positioning rods are slidably connected in the positioning grooves to fix the lower mold and the upper mold in the box-type mounting frame. When the lower mold is removed, the box-type mounting frame can serve as a protective box.

[0009] Furthermore, it also includes a guiding mechanism, which includes a guide rod fixed on a C-shaped mounting bracket, a guide sleeve fixedly connected to the upper box-type mounting bracket, and the guide rod passing through the guide sleeve and slidably connected to it.

[0010] Furthermore, a connecting block is fixedly connected to the positioning rod, and a spring is fixedly connected to the connecting block. The other end of the spring is fixedly connected to the box-type mounting bracket.

[0011] Furthermore, a base is installed at the bottom of the C-shaped mounting bracket, and multiple fixing holes are provided through the base.

[0012] Furthermore, two through slots are provided through the box-type mounting bracket on the lower side, and two tie rods located in the through slots are fixedly connected to the lower mold.

[0013] Furthermore, the through slot is provided at the upper end of the box-type mounting bracket.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention simplifies the disassembly of the upper and lower molds without requiring additional tools, providing convenience for workers. Meanwhile, the lower box-type mounting bracket can serve as a protective box, thus shielding the items when the hydraulic cylinder drives the extrusion mold to press them, preventing them from breaking and splashing and causing injury to surrounding workers.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a single-column C-type hydraulic press for easy mold fixing, comprising:

[0023] C-type mounting bracket 1, on which a hydraulic cylinder 2 is mounted, and a mounting rod is mounted on the output end of the hydraulic cylinder 2; wherein, a base is mounted on the bottom of the C-type mounting bracket 1, and multiple fixing holes are provided through the base, so that the base can be placed on the corresponding bracket, and bolts are used to install the base on the bracket through the fixing holes.

[0024] The mold assembly includes a fixed mounting rod and a box-type mounting bracket 5 on the C-shaped mounting bracket 1. An upper mold 13 is slidably connected inside the upper box-type mounting bracket 5, and a lower mold 6 is slidably connected inside the lower box-type mounting bracket 5. To ensure the stable up-and-down movement of the upper box-type mounting bracket 5, a guide mechanism is also included. The guide mechanism includes a guide rod 3 fixed on the C-shaped mounting bracket 1, and a guide sleeve 4 fixedly connected to the upper box-type mounting bracket 5. The guide rod 3 passes through the guide sleeve 4 and is slidably connected to it. The up-and-down movement of the box-type mounting bracket 5 drives the guide sleeve 4 to move up and down. Guided by the guide rod 3, the box-type mounting bracket 5 can be guided, thereby ensuring the stable up-and-down movement of the box-type mounting bracket 5.

[0025] The mold assembly includes two positioning rods 12 that pass through and are slidably connected to the box-type mounting frame 5. Both the lower mold 6 and the upper mold 13 are provided with two positioning grooves 9. The positioning rods 12 are slidably connected within the positioning grooves 9 to fix the lower mold 6 and the upper mold 13 within the box-type mounting frame 5. To ensure that the lower mold 6 and the upper mold 13 are stably fixed within the box-type mounting frame 5, a connecting block 10 is fixedly connected to the positioning rod 12, and a spring 11 is fixedly connected to the connecting block 10. The other end of the spring 11 is fixedly connected to the box-type mounting frame 5. At this time, the spring 11 is in a stretched state, which can pull the connecting block 10 and the positioning rod 12, ensuring that the positioning rod 12 is stably positioned within the positioning groove 9, thus fixing the lower mold 6 and the upper mold 13.

[0026] When it is necessary to disassemble and replace the lower mold 6 and the upper mold 13, the worker can pull the connecting block 10 to move the positioning rod 12 and remove it from the positioning groove 9. To remove the lower mold 6, two workers work together to move the positioning rod 12 out of the positioning groove 9. Since the lower box-type mounting frame 5 has two through grooves 7, and the lower mold 6 is fixedly connected to two pull rods 8 located in the through grooves 7, the through grooves 7 are set through the upper end of the box-type mounting frame 5. Then, the worker can move the lower mold 6 up by holding the pull rods 8 and move it out of the box-type mounting frame 5, so that the lower mold 6 can be removed. For the disassembly of the upper mold 13, the worker starts the hydraulic cylinder 2 to drive the box-type mounting frame 5 and the upper mold 13 to move down until the upper mold 13 and the lower mold 6 are against each other. The worker pulls the connecting block to make the positioning rod 12 disengage from the positioning groove 9. At this time, the upper mold 13 is no longer positioned, and the hydraulic cylinder 2 can drive the box-type mounting frame 5 to reset. At this time, the upper mold 13 is located on the lower mold 6, and the two can be removed together without the need for external tools, making disassembly simpler.

[0027] Remove the lower mold 6. The box-type mounting frame 5 can serve as a protective box. If this device is used to perform pressure testing on an item, the operator can remove the upper mold 13 and replace it with the corresponding extrusion mold. Remove the lower mold 6. At this time, the box-type mounting frame 5 below is box-shaped and can serve as a protective box. When the hydraulic cylinder 2 drives the extrusion mold to move down and extrude the item, it can shield the item and prevent it from breaking and splashing, which could cause injury to the surrounding operators.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
