Description

Technical Field

[0001] This utility model relates to the field of hot pressing equipment technology, and specifically discloses an automatic hot pressing device for irregularly shaped inner linings of ceramic gift boxes. Background Technology

[0002] Due to their fragile nature, ceramic products generally require cushioning linings for storage, transportation, and gift packaging. These linings are typically made of thermoplastic materials such as EVA and pearl cotton through a thermoforming process to create irregularly shaped cavities that precisely conform to the shape of the ceramic product. Existing thermoforming equipment usually includes a frame, a hydraulic drive mechanism fixed above the frame, a thermoforming upper mold driven by this mechanism, and a worktable below to hold the blank and the lower mold. By hydraulically driving the upper and lower molds to close, the blank placed inside is heated and pressurized to form a lining of a specific shape. This basic structure provides the fundamental conditions for the automated production of linings.

[0003] However, existing hot pressing equipment suffers from several drawbacks. Firstly, the upper mold generates a significant instantaneous impact force when hydraulically pressed down. This rigid contact can easily lead to mold damage due to stress concentration, and may also cause uneven pressure on the blank, affecting the dimensional accuracy and surface quality of the inner lining, as well as generating considerable equipment noise and vibration. Secondly, to meet the diverse demands of ceramic products, frequent changes to lower molds of different shapes are required. Traditional lower molds are often directly fixed with bolts, resulting in cumbersome replacement processes and poor positioning accuracy, severely restricting the production line's changeover efficiency and the flexibility of small-batch customized production.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0017] Please see Figure 1-4 An automatic hot-press forming device for irregularly shaped inner linings of ceramic gift boxes includes a base 1, a back plate 2 fixedly connected to the rear of the upper end face of the base 1, an mounting plate 3 fixedly connected to the upper front end face of the back plate 2, a hydraulic cylinder 4 mounted on the upper end face of the mounting plate 3, the output end of the hydraulic cylinder 4 passing through the mounting plate 3 and fixedly connected to a drive plate 5 located directly below the mounting plate 3, a hot-press plate 6 disposed directly below the drive plate 5, two buffer rods 7 fixedly connected to the upper end face of the hot-press plate 6, the other ends of the two buffer rods 7 being slidably connected to the drive plate 5 through the drive plate 5, and an upper mold 8 mounted on the lower end face of the hot-press plate 6. The upper surface of the base 1 is fixedly connected to two left and right distributed slide rails 9. The upper surface of each slide rail 9 is slidably connected to a slider 10. The upper surface of each slider 10 is fixedly connected to a support plate 11. The upper surface of the support plate 11 is provided with a positioning groove 12. The lower mold 13 is detachably connected inside the positioning groove 12.

[0018] In this embodiment: the hydraulic cylinder 4 installed on the mounting plate 3 at the front end of the back plate 2 drives the drive plate 5 to move. The drive plate 5 is floatingly connected to the hot press plate 6 on which the upper mold 8 is installed through two buffer rods 7 with springs 14. This structure allows the pressure output by the hydraulic cylinder 4 to be smoothly transmitted to the hot press plate 6 through the drive plate 5 and springs 14, realizing the flexible transformation of rigid impact, effectively avoiding stress concentration and vibration noise at the moment of mold closing, ensuring the quality of the inner lining forming surface and the mold life. The lower mold 13 is initially positioned by the positioning groove 12 on the sliding support plate 11. The support plate 11 can be moved out as a whole by the bottom slider 10 cooperating with the slide rail 9 on the base 1, which facilitates the quick replacement and maintenance of the lower mold 13. Precise positioning is achieved by the electric push rod 17 driving the clamping plate 18 to clamp the lower mold 13, and by the pneumatic pin 19 on the base 1 being inserted into the insertion hole 20 at the bottom of the support plate 11. This ensures the absolute accuracy and stability of the position of the lower mold 13 during the production process, thereby meeting the dual requirements of changeover efficiency and positioning accuracy in multi-variety, small-batch production.

[0019] As a technical optimization of this utility model, springs 14 located between the drive plate 5 and the hot press plate 6 are sleeved on the outer walls of both buffer rods 7.

[0020] In this embodiment: when the drive plate 5 presses down, it first compresses the spring 14, converting the linear kinetic energy of the hydraulic cylinder 4 into the potential energy of the spring 14. Then, through the elastic release of the spring 14, the pressure is smoothly and evenly transmitted to the hot plate 6, significantly reducing the impact and equalizing the pressure distribution. The spring 14's reset action assists the hot plate 6 in returning to its original position.

[0021] As a technical optimization of this utility model, two guide rods 15 are fixedly connected to the upper end face of the drive plate 5, and the other ends of the two guide rods 15 are slidably connected to the mounting plate 3 through the plate.

[0022] In this embodiment, it plays a guiding and stabilizing role, limiting the drive plate 5 to only vertical translation under the drive of the hydraulic cylinder 4, effectively preventing the drive plate 5 and the hot press plate 6 connected to it from deflecting or shaking during the movement, and ensuring the coaxiality and positional accuracy of the upper mold 8 and the lower mold 13 when they are closed.

[0023] As a technical optimization of this utility model, upright plates 16 are fixedly connected to the left and right sides of the upper end face of the support plate 11, and electric push rods 17 are installed on the opposite sides of the two upright plates 16. Clamping plates 18 are fixedly connected to the output ends of the two electric push rods 17.

[0024] In this embodiment, the clamping plate 18 provides an automatically controllable lateral clamping force to reliably fix the lower mold 13 placed in the positioning groove 12 from both sides, preventing it from moving during the lining molding process.

[0025] As a technical optimization of this utility model, a pneumatic pin 19 is embedded in the upper end surface of the base 1, and a socket 20 matching the pneumatic pin 19 is opened at the bottom of the support plate 11.

[0026] In this embodiment, the pneumatic pin 19 cooperates with the insertion hole 20 to achieve precise positioning and mechanical locking of the pallet 11 at the working position, overcoming the gap error that may exist if the positioning is based solely on the slide rail 9 and slider 10, and ensuring the absolute accuracy of the position of the lower mold 13 in the horizontal plane when the mold is closed.

[0027] As a technical optimization of this utility model, a control panel 21 is installed on the side wall of the back plate 2, and the hydraulic cylinder 4, electric push rod 17 and pneumatic pin 19 are all electrically connected to the control panel 21.

[0028] In this embodiment, the control panel 21 is electrically connected to the various actuators for centralized control, making operation and control convenient.

[0029] As a technical optimization of this utility model, the clamping surface of the clamping plate 18 is fixedly connected with a rubber pad 22.

[0030] In this embodiment, the flexibility and high coefficient of friction of the rubber material are utilized to protect the side wall of the lower mold 13 from being scratched by the hard clamping plate 18 during clamping, and to increase the friction force to make the clamping more secure.

[0031] The working principle and usage process of this utility model are as follows: In the initial state, the support plate 11 is pulled out to the mold changing position through the slide rail 9 and slider 10 mechanism. The required lower mold 13 is placed into the positioning groove 12 of the support plate 11. Then, the support plate 11 is pushed back to the working position. At this time, the pneumatic pin 19 extends under the command of the control panel 21 and inserts into the insertion hole 20 at the bottom of the support plate 11 to achieve precise positioning and locking. Subsequently, the electric push rods 17 on both sides are activated, pushing the clamping plate 18 to reliably clamp the lower mold 13 in the working position through the rubber pad 22. The operator places the inner lining blank into the cavity of the lower mold 13 and starts the operation. The hydraulic cylinder 4 pushes the drive plate 5 downward along the guide rod 15. The drive plate 5 contacts and compresses the spring 14 on the buffer rod 7. The buffering effect of the spring 14 makes the upper mold 8 connected to the hot press plate 6 smoothly and gently close with the lower mold 13, and heats and pressurizes the blank to form it. After the forming is completed, the hydraulic cylinder 4 drives the drive plate 5 to rise, and the buffer rod 7 and spring 14 return to their original positions, driving the upper mold 8 away from the finished product. Then the electric push rod 17 releases the clamping plate 18, and the pneumatic pin 19 retracts, so that the support plate 11 can be pulled out again, the formed inner liner finished product can be removed, and the next cycle can be prepared.
