[0004] Based on the above, the present inventor found that there are the following problems: in the above patent, the extruded foam box in the open containing box can be ejected through the ejector assembly, and the ejector plate can remove the foam particles adsorbed on the inner wall of the open containing box, so as to improve the cleanliness of the interior of the open containing box and facilitate the next use, but the extrusion block in the above patent is inconvenient for technicians to replace when extruding different models of foam boxes, and the ejector plate cannot be inclined, so the formed foam box needs to be removed by workers, thereby reducing the work efficiency.

[0005] Therefore, in view of the above, the existing structure and defects are improved, and an EPS foam box production is pressed together with device is provided to achieve the purpose of having more practical value. Utility model content

[0006] The purpose and effect of the utility model of an EPS foam box production is pressed together with device are achieved by the following specific technical means:

[0007] A pressing device for producing EPS foam boxes includes a workbench, a plurality of support frames mounted on the top of the workbench, an mounting plate mounted on the top of the support frames, a hydraulic cylinder mounted on the top of the mounting plate, the output end of the hydraulic cylinder extending to the bottom end of the mounting plate and mounted with a clamping assembly, a lower mold mounted on the top of the workbench, a plurality of through holes provided on the bottom surface of the lower mold and the surface of the workbench, a top plate slidably mounted on the inner side of the lower mold, a push rod movably mounted on the bottom end of the top plate, and a mounting frame mounted on the bottom end of the workbench, a pair of first cylinders mounted on the bottom end of the mounting frame, and a pair of second cylinders mounted on the bottom end of the mounting frame, both the first cylinders and the second cylinders being movably connected to the push rods.

[0008] Furthermore, the top end of the top rod is rotatably connected to the top plate via a rubber joint.

[0009] Furthermore, a rotating seat is rotatably mounted on the bottom end of the push rod, and the rotating seat is threadedly connected to the output ends of the first cylinder and the second cylinder respectively.

[0010] Furthermore, the periphery of the rotating seat matches the perforation.

[0011] Furthermore, conveying pipes are installed on both sides of the lower mold.

[0012] Furthermore, the clamping assembly includes a mounting base, the bottom end of which is provided with a sliding groove, a bidirectional lead screw is rotatably mounted in the sliding groove, a pair of sliders are threaded to both ends of the bidirectional lead screw, a pair of clamping seats are mounted at the bottom end of the sliders, the clamping seats are located outside the mounting base, and an upper mold is clamped between the pair of clamping seats.

[0013] Furthermore, a motor is mounted on one side of the mounting base, and the output end of the motor is connected to a bidirectional lead screw drive.

[0014] Furthermore, a pair of limiting rods are installed on both sides of the top of the mounting base, and the pair of limiting rods penetrate the mounting plate.

[0015] Furthermore, a guide seat is installed at the top of the workbench on one side of the lower mold, and the surface of the guide seat is provided with a guide groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Through the coordinated use of the first cylinder, the second cylinder, the ejector rod, the perforation, and the top plate, the output ends of the first and second cylinders drive the ejector rod to move upwards, while the perforation facilitates the movement of the output ends of the first and second cylinders. The first and second cylinders drive the ejector rod to push out the top plate, and the top plate pushes out the foam box in the lower mold. After being pushed out, since both the first and second cylinders are movably connected to the ejector rod, the second cylinder continues to drive the ejector rod upwards, causing the top plate to tilt. At this time, the foam box pushed out by the top plate falls off, improving work efficiency.

[0018] The top of the top rod is connected to the top plate by a rubber joint, which allows the top plate to be tilted easily, thus improving its practicality.

[0019] The rotating seat is threadedly connected to the output ends of the first and second cylinders respectively. Rotating the rotating seat disengages it from the output ends of the first and second cylinders, making it easier to replace the top plate after the lower mold is replaced. The replacement top plate matches the inner wall of the lower mold, improving practicality.

[0020] By using the motor, double-acting lead screw, slider, and clamping seats in coordination, the motor rotates and drives the double-acting lead screw to rotate. At this time, the sliders at both ends of the double-acting lead screw move towards each other, driving a pair of clamping seats to hold the upper mold. When changing the upper mold, the motor drives the double-acting lead screw to rotate in the opposite direction, and the pair of clamping seats move to both sides, so that the upper mold can be changed, thus improving work efficiency.

[0021] By using the guide seat and guide groove together, the molded foam box will fall onto the guide seat during tilting and then slide away through the guide groove, reducing manual intervention, freeing up the hands of technicians and improving work efficiency. Attached Figure Description

[0030] Example:

[0031] As attached Figure 1 To be continued Figure 3 As shown:

[0032] This utility model provides a pressing device for EPS foam box production, including a workbench 1. Several support frames 2 are mounted on the top of the workbench 1, and mounting plates 3 are mounted on the top of the support frames 2. A hydraulic cylinder 4 is mounted on the top of the mounting plate 3, and the output end of the hydraulic cylinder 4 extends to the bottom end of the mounting plate 3 and is fitted with a clamping assembly. A lower mold 9 is mounted on the top of the workbench 1. Several through holes 15 are provided on the bottom surface of the lower mold 9 and the surface of the workbench 1. A top plate 12 is slidably mounted on the inner side of the lower mold 9, and a push rod 13 is movably mounted on the bottom end of the top plate 12. A mounting frame 16 is mounted on the bottom end of the workbench 1, and a pair of first cylinders 17 are mounted on the bottom end of the mounting frame 16. A clamping assembly is also mounted on the bottom end of the mounting frame 16. A pair of second cylinders 23 are provided. Both the first cylinder 17 and the second cylinder 23 are movably connected to the ejector rod 13. Through the cooperation of the first cylinder 17, the second cylinder 23, the ejector rod 13, the through hole 15, and the top plate 12, the output ends of the first cylinder 17 and the second cylinder 23 drive the ejector rod 13 to move upward. The through hole 15 facilitates the movement of the output ends of the first cylinder 17 and the second cylinder 23. The first cylinder 17 and the second cylinder 23 drive the ejector rod 13 to push out the top plate 12. The top plate 12 pushes out the foam box in the lower mold 9. After being pushed out, since the first cylinder 17 and the second cylinder 23 are both movably connected to the ejector rod 13, the second cylinder 23 continues to drive the ejector rod 13 upward, causing the top plate 12 to tilt. At this time, the foam box pushed out by the top plate 12 falls off, improving work efficiency.

[0033] The top end of the top rod 13 is rotatably connected to the top plate 12 via a glue joint. This rotatable connection between the top end of the top rod 13 and the top plate 12 facilitates the tilting of the top plate 12 and improves its practicality.

[0034] The bottom end of the push rod 13 is rotatably mounted with a rotating seat 14. The rotating seat 14 is threadedly connected to the output ends of the first cylinder 17 and the second cylinder 23 respectively. By rotating the rotating seat 14, the rotating seat 14 is disengaged from the output ends of the first cylinder 17 and the second cylinder 23. After the lower mold 9 is replaced, it is convenient to replace the top plate 12. The replacement of the top plate 12 that matches the inner wall of the lower mold 9 improves practicality.

[0035] The outer periphery of the rotating seat 14 matches the perforation 15.

[0036] The lower mold 9 is equipped with conveying pipes 22 on both sides, which are connected to an external material supply box to inject raw materials into the lower mold 9.

[0037] The clamping assembly includes a mounting base 6, the bottom end of which is provided with a sliding groove 18. A bidirectional lead screw 19 is rotatably mounted in the sliding groove 18. A pair of sliders 20 are threaded to both ends of the bidirectional lead screw 19. A pair of clamping seats 21 are mounted at the bottom end of the sliders 20. The clamping seats 21 are located outside the mounting base 6, and the upper mold 8 is clamped between the pair of clamping seats 21.

[0038] A motor 7 is installed on one side of the mounting base 6. The output end of the motor 7 is connected to the bidirectional lead screw 19. Through the cooperation between the motor 7, the bidirectional lead screw 19, the slider 20, and the clamping seat 21, the motor 7 rotates and drives the bidirectional lead screw 19 to rotate. At this time, the sliders 20 at both ends of the bidirectional lead screw 19 move towards each other, driving a pair of clamping seats 21 to hold the upper mold 8. When changing the upper mold 8, the motor 7 drives the bidirectional lead screw 19 to rotate in the opposite direction, and the pair of clamping seats move to both sides, so that the upper mold 8 can be changed, which improves the work efficiency.

[0039] Among them, a pair of limiting rods 5 are installed on both sides of the top of the mounting base 6, and the pair of limiting rods 5 penetrate the mounting plate 3.

[0040] The top of the workbench 1 is equipped with a guide seat 10 located on one side of the lower mold 9. The surface of the guide seat 10 is provided with a guide groove 11. Through the cooperation between the guide seat 10 and the guide groove 11, the molded foam box will fall onto the guide seat 10 during the tilting process and then slide away through the guide groove 11, reducing manual intervention, freeing up the hands of technicians and improving work efficiency.

[0041] The specific usage and function of this embodiment are as follows:

[0042] First, check the integrity of the device. Only after confirming it is correct can it be used. During use, the motor 7 rotates, driving the bidirectional lead screw 19 to rotate. At this time, the sliders 20 at both ends of the bidirectional lead screw 19 move towards each other, driving a pair of clamping seats 21 to hold the upper mold 8. The conveying pipe 22 connects to an external feeding box, filling the lower mold 9 with raw material. The hydraulic cylinder 4 drives the mounting seat 6 to descend, and the mounting seat 6 drives the upper mold 8 to descend, extruding and molding the foam in the lower mold 9. The output ends of the first cylinder 17 and the second cylinder 23 drive the ejector rod 13 to move upwards. The perforation 15 facilitates the movement of the output ends of the first cylinder 17 and the second cylinder 23. The first cylinder 17 and the second cylinder 23 drive the ejector rod 13 to push out the top plate 12. The top plate 12 pushes out the foam box in the lower mold 9. After being pushed out, due to the ejector rod... The top of the top rod 13 is rotatably connected to the top plate 12 using a rubber joint. The second cylinder 23 continues to drive the top rod 13 upward, causing the top plate 12 to tilt. During the tilting process, the molded foam box will fall onto the guide seat 10 and then slide away through the guide groove 11, reducing manual intervention and freeing up the hands of technicians. When changing the upper mold 8, the motor 7 drives the bidirectional lead screw 19 to rotate in the opposite direction, and a pair of clamping seats move to both sides, so that the upper mold 8 can be changed, improving work efficiency. Rotating the rotating seat 14 disengages the rotating seat 14 from the output ends of the first cylinder 17 and the second cylinder 23. After the lower mold 9 is changed, it is convenient to change the top plate 12. The top plate 12 that matches the inner wall of the lower mold 9 is replaced, improving practicality. This device has a novel overall design and simple structure, so it is worth promoting and using widely.
