A hydraulic press is generally composed of three parts: the machine (main machine), a power system, and a hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses. The patent with publication number CN213410024U discloses a hydraulic press, including a base, a frame, a punch, a recovery component, a clamping component, and a limit component. The base is placed with a workpiece to be processed, the frame is fixed to the base, the punch can be raised and lowered on the frame, the punch processes the workpiece to be processed, and the clamping component includes a pressing plate. The push plate and the pressing plate cooperate to achieve the limit of the workpiece to be processed; the waste chips enter the recycling box through the opening of the recycling box for storage, which is convenient for recycling waste chips and improving the use efficiency of the hydraulic press.

[0003] However, the hydraulic press is located below the pressure plate during operation, which poses certain operational safety risks, and needs to be stopped for demoulding, which is inefficient. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a hydraulic press with a steering mechanism, which solves the problems of being located below a pressure plate during operation, posing certain operational safety hazards, and requiring the machine to be shut down for demoulding, which is inefficient.

The support frame includes a connecting horizontal plate and two supporting columns, one of which is coaxially located in the hole, and the two ends of the connecting horizontal plate are respectively fixedly connected to the top ends of the two supporting columns;

[0008] The hydraulic cylinder is fixed on the connecting horizontal plate, and the piston rod end of the hydraulic cylinder is downward and fixedly mounted with an upper mold;

[0009] A rotating disc is coaxially rotatably arranged on the workbench, and three placement positions are arranged around the circumference of the rotating disc, on which the lower mold is placed, and the rotating disc can be rotated so that the lower mold is located directly below the upper mold.

[0010] Preferably, a cylinder is coaxially fixedly connected to the bottom of the rotating disk, and the cylinder is coaxially rotatably arranged in the workbench. A ring is connected to the bottom of the cylinder, and a first gear is fixedly connected to the outside of the ring. A cavity is provided in the workbench, and a motor is arranged in the cavity.

[0011] Preferably, both ends of the upper mold are connected with positioning plates, and the supporting column is provided with a vertical groove, and the two positioning plates are respectively slidably connected in the vertical grooves adjacent thereto along the vertical direction.

[0012] Preferably, a buffer plate is slidably provided at the lower part of the vertical slot, and a compression spring is fixedly connected between the buffer plate and the lower wall of the vertical slot.

[0013] Preferably, a limiting rod is fixedly connected to a side edge of the buffer plate, a vertical hole is provided on a side wall of the vertical slot, and the limiting rod extends out of the vertical hole.

[0014] The beneficial effects of the utility model are:

[0015] The rotating disc rotates on the workbench, so that the three lower molds can be located directly below the upper mold in sequence.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the technical solutions in the present invention are further described below in conjunction with the accompanying drawings and embodiments.

[0021] See also Figure 1 and Figure 2 As shown, a hydraulic press with a steering mechanism comprises: a workbench 1, a support frame, a hydraulic cylinder 2, an upper mold 3 and a lower mold 4; the workbench 1 is cylindrical, a hole is coaxially provided in the middle of the workbench 1, the support frame comprises a connecting cross plate 51 and two support columns 52, one of the support columns 52 is coaxially located in the hole, and the two ends of the connecting cross plate 51 are respectively fixedly connected to the top ends of the two support columns 52; the hydraulic cylinder 2 is fixed on the connecting cross plate 51, and the piston rod end of the hydraulic cylinder 2 is downwardly and fixedly installed with the upper mold 3; a rotating disk 6 is coaxially rotatably provided on the workbench 1, and three placement positions 61 are provided around the circumference of the rotating disk 6, the lower mold 4 is placed on the placement position 61, and the lower mold 4 can be located directly below the upper mold 3 by rotating the rotating disk 6.

[0022] When the device is in use, the raw material to be extruded is introduced into one of the lower molds 4, and then the rotating disk 6 is controlled to rotate so that the lower mold 4 containing the raw material is located directly below the upper mold 3, and then the hydraulic cylinder 2 works so that the upper mold 3 presses down to perform compression molding on the raw material in the lower mold 4. At the same time, the raw material can be introduced into another lower mold 4. After the compression molding is completed, the rotating disk 6 can be controlled to continue to rotate so that the lower mold 4 after the compression molding is completed is moved out for easy demoulding, and at the same time, the other lower mold 4 is located directly below the upper mold 3; the rotating disk 6 rotates on the workbench 1 so that the three lower molds 4 can be located directly below the upper mold 3 in turn, so that when one of the lower molds 4 is moved to other positions for demoulding, the other lower mold 4 can be moved to the bottom of the upper mold 3 for work, so that the hydraulic press can work uninterruptedly, thereby improving the working efficiency of the hydraulic press and avoiding safety hazards.

[0023] Furthermore, if Figure 1 As shown, it is a specific structure for controlling the rotation of the rotating disc 6. The bottom of the rotating disc 6 is coaxially fixedly connected with a cylinder 7, and the cylinder 7 is coaxially rotatably arranged in the workbench 1. The bottom of the cylinder 7 is connected with a ring, and the first gear is fixedly connected to the outside of the ring. A cavity is provided in the workbench 1, and a motor 11 is arranged in the cavity. The output end of the motor 11 is connected to a second gear meshing with the first gear. The motor 11 is started to drive the second gear to rotate, thereby driving the first gear to rotate, and the cylinder 7 rotates, driving the rotating disc 6 to rotate.

[0024] Furthermore, if Figure 1 As shown, both ends of the upper mold 3 are connected with positioning plates 31, and a vertical slot 53 is provided on the support column 52. The two positioning plates 31 are respectively slidably connected in the vertical slots 53 adjacent thereto in the vertical direction. When the upper mold 3 moves up and down, the positioning plates 31 move up and down in the vertical slots 53. The positioning plates 31 are provided to improve the stability of the upper mold 3 during the movement process.

[0025] Furthermore, if Figure 1 As shown, a buffer plate 8 is slidably provided at the lower part of the vertical slot 53, and a compression spring 9 is fixedly connected between the buffer plate 8 and the lower wall of the vertical slot 53. The positioning plate 31 moves downward under the drive of the upper mold 3, and the positioning plate 31 continues to move downward after contacting the buffer plate 8, so that the compression spring 9 is compressed, so that the upper mold 3 is buffered to a certain extent during the pressing process, so as to avoid excessive punching force resulting in a reduction in the service life of the upper mold 3 and the lower mold 4.

[0026] Furthermore, in order to limit the movement of the buffer plate 8 , a limiting rod 81 is fixedly connected to the side of the buffer plate 8 , and a vertical hole 54 is provided on the side wall of the vertical slot 53 , and the limiting rod 81 extends out of the vertical hole 54 .
