During the stamping process, the movable plate and the upper die move downward under the action of the hydraulic cylinder. When the movable plate moves downward, it drives two guiding rods to move downward, causing the guiding rods to penetrate into the guiding sleeves. When the guiding rods move inside the guiding sleeves, they first come into contact with a number of ball bearings. Through the cooperation between the guiding rods and the number of ball bearings inside the guiding sleeves, the upper die has an accurate guiding path when moving downward, avoiding deviation and error. And after the guiding rods pass through the number of ball bearings, they will come into contact with the sliders and squeeze the sliders to move downward. At this time, the spring is compressed and deformed, and under the action of the spring, the impact force of the downward movement of the upper die is effectively buffered;

[0017] 2. The device completes the knocking treatment of the push plate through the setting of the knocking structure. When demolding the formed steel plate, the motor can be started. The motor drives the second bevel gear to rotate. With the meshing of the second bevel gear and the first bevel gear, it drives the positive and negative lead screw to rotate, and then drives the two thread sleeves and the driving rack to approach or move away from each other. With the mutual cooperation between the driving rack and the incomplete gear, it drives the rotating shaft and the knocking hammer to rotate, so that the knocking hammer knocks the push plate below the steel plate. Through knocking, the adhesion strength between the steel plate and the push plate is reduced, and the steel plate can be more easily removed from the lower die, thereby improving the demolding efficiency and increasing the production speed.

[0024] Embodiment 1

[0025] Referring to Figures 1-3 , this embodiment provides a continuous press for steel plate extrusion molding, including a stamping base 1, a guiding structure and a knocking structure. It is characterized in that a box door 2 is arranged at the front end of the stamping base 1, an installation frame 3 is fixedly connected to the top end of the stamping base 1, a hydraulic cylinder 4 is installed at the top end of the installation frame 3, and the output end of the hydraulic cylinder 4 penetrates through the installation frame 3 and is fixedly connected to a movable plate 5.

[0027] In the use of this embodiment, first place the workpiece to be stamped in the lower die 28, and then start the hydraulic cylinder 4. Drive the upper die 6 to move downward through the hydraulic cylinder 4 to perform stamping on the workpiece to be stamped. During the stamping process, the movable plate 5 and the upper die 6 move downward under the action of the hydraulic cylinder 4. When the movable plate 5 moves downward, it will drive the two guide rods 7 to move downward, so that the guide rods 7 penetrate into the inside of the guide sleeves 8. When the guide rods 7 move in the guide sleeves 8, they will first come into contact with a number of balls 10. Through the cooperation between the guide rods 7 and the number of balls 10 inside the guide sleeves 8, the upper die 6 has an accurate guiding path when moving downward, avoiding deviation and error. And after the guide rods 7 pass through the number of balls 10, they will come into contact with the sliders 11 and squeeze the sliders 11 to move downward.

[0028] Embodiment 2

[0029] Referring to Figure 4 , this embodiment is based on the previous embodiment. The difference from the previous embodiment is that the knocking structure includes a positive and negative lead screw 16, an auxiliary rod 21, a threaded sleeve 22, a driving rack 23, a rotating shaft 24, an incomplete gear 25 and a knocking hammer 26.

The outer side wall of the connecting box 15 is fixedly connected with an auxiliary rod 21. Threaded sleeves 22 are threadedly connected to both the left and right sides of the positive and negative lead screw 16. The top ends of the threaded sleeves 22 are fixedly connected with driving racks 23. A rotating shaft 24 is rotatably connected inside the connecting box 15 and above the two driving racks 23. An incomplete gear 25 is fixedly connected to the outer side wall of the rotating shaft 24. The incomplete gear 25 is meshed and connected with the driving rack 23. A knocking hammer 26 is fixedly connected to the side of the rotating shaft 24 away from the incomplete gear 25.

[0030] The bottom end of the connecting box 15 is fixedly connected with a fixed box 18. A motor 19 is installed inside the fixed box 18.

The push plate 27 is adapted to the lower die 28.

[0032] When this embodiment is in use and demolding is required after the steel plate is extrusion-molded, the motor 19 can be started. The motor 19 drives the second bevel gear 20 to rotate. By means of the meshing of the second bevel gear 20 and the first bevel gear 17, the forward and reverse lead screw 16 is driven to rotate, thereby driving the two threaded sleeves 22 and the driving rack 23 to approach or move away from each other. By means of the mutual cooperation of the driving rack 23 and the incomplete gear 25, the rotating shaft 24 and the knocking hammer 26 are driven to rotate, so that the knocking hammer 26 knocks the push plate 27 below the steel plate. By knocking, the adhesion strength between the steel plate and the push plate 27 is reduced, and the steel plate can be more easily removed from the lower mold 28, thereby improving the demolding efficiency and increasing the production speed. Then, the electric push rod 14 is started, and the electric push rod 14 drives the connection box 15 and the push plate 27 to move upward to push the extrusion-molded steel plate out of the lower mold 28, so as to improve the efficiency of demolding the steel plate and facilitate the staff to take away the molded steel plate.
