[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] A hydraulic press for automatic vacuum cup preparation, such as Figure 1As shown, it includes a base 1, a connecting column 2, a support plate 3, a lifting plate 4 and a control panel 5. The connecting column 2 is provided with four and respectively connected to the support plate 3 and the base. The lifting plate 4 is horizontally arranged and moves up and down along the connecting column 2. A storage table 6 is provided on the base 1, and a molding groove 7 for accommodating the storage table 6 is provided on the lifting plate 4. A hydraulic system is provided on the supporting plate 3, and the hydraulic system includes a hydraulic pump, a hydraulic cylinder and a plurality of pipelines. A clamping arm 19 is provided on the base 1, and the clamping arm 19 is controlled by the control panel 5. A accommodating tube 20 for placing a sample is sleeved on the connecting column 2. Specifically, the accommodating tube 20 includes a fixing portion and a clamping portion. The fixing portion is sleeved on the connecting column, and the clamping portion is used to clamp the sample. By arranging the storage table 6 and the molding groove 7, when the sample is placed After being placed on the storage table 6, as the lifting plate 4 descends, the sample will contact the molding groove 7. As the molding groove 7 continues to descend, the inner wall of the molding groove 7 and the storage table 6 will squeeze the sample, thereby squeezing the sample into the shape of a thermos cup body. By setting the clamping arm 19 and the accommodating tube 20, the operator only needs to input parameters into the control panel 5 to realize the automatic operation process, which reduces the manpower demand and ensures production efficiency. At the same time, the centralized control of the control panel 5 reduces the risk of direct contact between the operator and mechanical parts, and improves the safety of the operation process. The hydraulic system allows precise control of the stretching force and speed to ensure uniform wall thickness and uniform force of the product, protect the product, and increase the strength and hardness of the product.

[0025] A moving device is provided on the side of the lifting plate 4 facing the storage table 6. The moving device includes a plurality of moving blocks 8 and a connecting rod 9. An extrusion block 10 is provided at one end of the connecting rod 9 away from the moving block 8. The moving device includes an open state and a closed state. When the moving device is in the open state, the plurality of moving blocks 8 are close to each other, and the plurality of extrusion blocks 10 are moved close to each other through the moving blocks 8 to form an extrusion circle. The diameter of the extrusion circle is smaller than the diameter of the forming groove 7. When the moving device is in the closed state, the plurality of moving blocks 8 are away from each other, and the extrusion block 10 is flush with the bottom surface of the lifting plate 4. By setting the moving device, the moving block 8 and the connecting rod 9 can adjust the position of the extrusion block 10, and the plurality of extrusion blocks can be moved to the position of the extrusion block 10. 10 are close to each other and form an extrusion circle, so that the sample can be extruded at the mouth of the cup, so that the sample does not need to be repeatedly carried, reducing the risk of collision of the sample during transportation, protecting the integrity of the sample, and one-time molding operation improves production efficiency. The design of the moving device makes the extrusion block 10 flush with the bottom surface of the lifting plate 4 in the closed state, which can reduce the damage of the sample when it comes into contact with the machine during movement or molding. The design of the moving device allows the size of the extrusion circle to be quickly switched, thereby reducing the time for changing molds or adjusting equipment, improving production efficiency, and at the same time, only the extrusion block 10 needs to be replaced to realize a variety of cup mouth styles of thermos cups.

[0026] The lifting plate 4 is provided with a slide groove for accommodating the sliding of the moving block 8. The length of the connecting rod 9 is adjustable. The connecting rod 9 includes a plurality of tube bodies 11. The length of the connecting rod 9 is controlled by the control panel 5. The length of the slide groove is greater than the sum of the lengths of the tube body 11, the extrusion block 10 and the moving block 8. The connecting rod 9 with adjustable length enables the machine to adapt to samples of different sizes, thereby improving the versatility and flexibility of the equipment. The length of the connecting rod 9 can be accurately controlled through the control panel 5 to ensure that the extrusion block 10 can accurately reach the predetermined position, thereby improving the accuracy of the molding process. The length design of the slide groove ensures that the moving block 8, the extrusion block 10 and the tube body 11 have sufficient moving space, thereby reducing interference and collision during machine operation and improving production efficiency.

[0027] Furthermore, an elastic rope 12 is provided between two adjacent extrusion blocks 10, and a groove 13 for accommodating the embedding of the elastic rope 12 is provided on the lifting plate 4. The cross-section of the groove 13 is arranged in an arc shape. When the moving device is in the open state, the elastic rope 12 is in a normal state. When the moving device is in the closed state, the elastic rope 12 is in a stretched state. The stretched state of the elastic rope 12 when the moving device is in the closed state can assist the extrusion block 10 to press against the inner wall of the slide groove, thereby ensuring the stability of the extrusion block 10 and preventing the extrusion block 10 from being damaged by detaching from the slide groove, protecting the extrusion block 10 and extending the service life of the equipment. Since the elastic rope 12 is in a stretched state when the moving device is in the closed state, when the moving block 8 starts to move, the elastic rope 12 will assist the two adjacent extrusion blocks 10 to approach each other, thereby playing an auxiliary guiding role, ensuring the formation of the extrusion ring, and improving the connection strength between the two adjacent extrusion blocks 10. The design of the arc-shaped groove 13 can reduce the wear of the elastic rope 12 during work and extend its service life.

[0028] A plurality of symmetrically arranged arc-shaped protrusions 14 are provided on the inner wall of the embedded groove 13, and the distance between two symmetrically arranged arc-shaped protrusions 14 is smaller than the width of the elastic cord 12. A groove 15 for accommodating the arc-shaped protrusions 14 is provided on the inner wall of the embedded groove 13, and a telescopic rod 16 whose length is controlled by the control panel 5 is provided in the groove 15. The two ends of the telescopic rod 16 are respectively connected to the bottom surface of the groove 15 and the arc-shaped protrusions 14. The arc-shaped protrusions 14 can ensure that the elastic cord 12 is stably positioned in the embedded groove 13 to prevent the elastic cord 12 from shifting when subjected to force, thereby ensuring the precise alignment and uniform force of the extrusion block 10, and the design of the arc-shaped protrusions 14 reduces the direct friction between the elastic cord 12 and the inner wall of the embedded groove 13, thereby extending the service life of the elastic cord 12, and the design of the telescopic rod 16 allows it to be retracted when the mobile device is opened, thereby reducing wear and potential damage.

[0029] An annular groove 17 is formed on the outer peripheral wall of the base 1, and the inner diameter of the annular groove 17 is equal to the diameter of the extrusion ring. The inner wall of the annular groove 17 and the extrusion block 10 are provided with arc surfaces and fit into each other. A baffle 18 for covering the annular groove 17 is slidably connected to the base 1. When the baffle 18 is pressed against the inner wall of the annular groove 17, the baffle 18 is flush with the panel of the base 1. The baffle 18 is controlled by the control panel 5. By setting the annular groove 17, when the sample is completed after the cup body is made and the cup mouth needs to be made, the outer wall of the sample can be squeezed by the extrusion ring, and the sample will be concave toward the annular groove 17 and press against the surface of the annular groove 17. The forming of the cup mouth is thus completed. Since the inner diameter of the annular groove 17 is equal to the diameter of the extrusion ring, the precise fit between the extrusion block 10 and the annular groove 17 is ensured, thereby improving the forming accuracy. The arc surface design on the inner wall of the annular groove 17 and the extrusion block 10 helps to make the sample cup mouth formed and beautiful during the forming process, while also protecting the mold and the sample and reducing wear and damage. The design of the baffle 18 allows the opening and closing of the annular groove 17 to be easily controlled by the control panel 5, thereby improving the convenience and safety of operation, while also protecting the inner wall of the annular groove 17 from damage, thereby playing a good protective role.

[0030] The present invention further comprises the following steps: S1: Start the equipment, start the hydraulic system through the control panel 5, and perform a system self-check to ensure that all components are in normal working condition; S2: Input parameters through the control panel 5, including but not limited to the position of the moving block 8, the length of the telescopic rod 16, the pressure setting of the hydraulic system, etc.; S3: placing the sample, the operator places the sample into the clamping portion of the containing tube 20, ensures that the sample is fixed and stable, and starts the equipment; S4: The clamping arm 19 starts to operate according to the instruction of the control panel 5, takes out the sample to be manufactured from the clamping part, places it on the storage table 6, the lifting plate 4 descends, the storage table 6 enters the molding groove 7, and the base 1 and the lifting plate 4 start to extrude and mold the sample; S5: Raise the lifting plate 4, the moving block 8 moves and causes the extrusion block 10 to move out of the slide groove to form an extrusion ring, the baffle 18 slides downward to expose the annular groove 17, and the lifting plate 4 is lowered to perform a cup-mouth extrusion operation on the sample; S6: After the operation is completed, the lifting plate 4 and the base 1 move away, and the clamping arm 19 clamps the molded sample and places it in the finished product area, ending the operation.

[0031] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
