Description

Technical Field

[0001] This utility model relates to the field of foam production technology, and in particular to a high-temperature hot press for foam production. Background Technology

[0002] Foam is a porous material with excellent cushioning, shock absorption, heat insulation, and sound insulation properties. It consists of many small, independent open or closed pores, giving it lightweight, softness, and good elasticity. Depending on the material and manufacturing process, foam can be classified into various types, such as polyurethane foam, polyethylene foam, and EVA foam. These different types of foam differ in performance and are suitable for different applications. A high-temperature hot press for foam production is a specialized piece of equipment used for high-temperature hot pressing of foam materials. This equipment plays a crucial role in foam production, not only improving production efficiency but also ensuring consistent product quality.

[0003] To address this, patent CN214324153U discloses a hydraulic high-temperature hot press for foam, specifically relating to the field of hot press technology. The press includes a housing with bases fixedly connected to the four corners at the bottom and a control panel fixedly connected to the top of the front end. This invention features a discharge structure inside the fixed base. After the foam is hot-pressed, a turntable movably connected to the top of the fixed horizontal plate rotates, simultaneously driving an adjusting rod fixedly connected thereto to rotate. As the adjusting rod rotates, it drives an adjusting sleeve to move up and down outside the adjusting sleeve via a threaded connection, thereby raising and lowering a lifting plate fixed thereto. Simultaneously, the lifting plate raises and lowers, pushing the top plate up and down via a connecting rod, thus ejecting the molded foam for easy removal by operators, reducing work hazards. Furthermore, the sliding structure formed between the sliding sleeve and the stabilizing rod stabilizes the lifting plate, making it highly operable.

[0004] The hydraulic high-temperature hot press for foam mentioned above uses bolts to install and fix the heating plate during use. However, multiple holes need to be connected by bolts to fix the heating plate, which is relatively complicated during installation, increasing the difficulty and time cost of installation, and making it inconvenient to install the heating plate quickly. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature hot press for foam production, which solves the problem that existing high-temperature hot presses for foam production are not easy to install quickly.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-temperature hot press for foam production, including a housing and an installation structure;

[0007] The interior of the box is provided with a processing cavity;

[0008] The processing cavity is equipped with a mounting structure, which includes a hydraulic rod fixed to the top of the housing. A movable plate is fixed to the output end of the hydraulic rod inside the processing cavity. An mounting plate is installed at the bottom of the movable plate. T-shaped grooves are fixed on both sides of the top of the mounting plate. A T-shaped slider is provided inside the movable plate outside the T-shaped groove. A fixing shell is fixed on both sides of the top of the movable plate. A pin is installed inside the fixing shell. A return spring is installed on the outside of the pin. A return plate is fixed to the outside of the pin at the bottom of the return spring. An insertion hole is provided inside the T-shaped slider outside the pin.

[0009] Preferably, guide rods are fixed at the edges of the processing cavity, guide holes are provided inside the movable plate on the outer side of the guide rod, shock-absorbing sleeves are fitted on the outer side of the bottom end of the guide rod, a hot press plate is fixed at the bottom end of the mounting plate, and a movable block is fixed at the top end of the pin.

[0010] Preferably, the guide rods are evenly spaced inside the processing cavity, and the two ends of the guide rods are fixedly connected to the two ends inside the processing cavity, respectively. The shock-absorbing sleeve is made of sponge material.

[0011] With the above structure, the moving plate slides on the outside of the guide rod through the guide hole during use, which facilitates hot pressing. In addition, by setting the shock-absorbing sleeve, the hot pressing plate is buffered and damped during the hot pressing process, thus effectively protecting the hot pressing plate.

[0012] Preferably, the T-shaped sliders are symmetrically distributed at the top of the mounting plate, the T-shaped sliders and the moving plate are slidably connected by T-shaped grooves, the pins and the reset plate are telescopically connected by a reset spring, and the T-shaped sliders and the pins are engaging through a socket.

[0013] With the above structure, the hot press plate can be quickly installed by sliding the T-shaped slider into the T-shaped groove during use, which makes it easy to lock the hot press plate at the bottom of the moving plate, thus facilitating the replacement of different models of hot press plates. The pin is inserted into the hole to fix the T-shaped slider, thereby further locking the T-shaped slider inside the T-shaped groove.

[0014] Preferably, a mold is installed at the top of the processing cavity, and a demolding structure is provided inside the bottom box of the mold. The demolding structure includes an internal cavity inside the bottom box of the processing cavity. A motor is fixed to one side of the internal cavity, and a rotating shaft is fixed to the output end of the motor. A first bevel gear is fixed to one end of the rotating shaft. A second bevel gear is installed on one side of the first bevel gear. A limit shell is fixed inside the internal cavity at the top of the second bevel gear. A threaded rod is installed inside the second bevel gear. A through hole is provided inside the outer box of the threaded rod. Limit grooves are provided at the top of the internal cavities on both sides of the threaded rod. Limit blocks are fixed on both sides of the threaded rod inside the limit grooves. A push plate is fixed to the top of the threaded rod. A reserved groove is provided inside the outer box of the push plate.

[0015] Preferably, the first bevel gear and the second bevel gear are meshed together, and the threaded rod is threadedly connected to the second bevel gear.

[0016] Preferably, the limiting blocks are symmetrically distributed on both sides of the threaded rod, and the top end of the threaded rod extends through the interior of the limiting shell to the interior of the reserved groove and is fixedly connected to the bottom end of the push plate.

[0017] With the above structure, the second bevel gear is prevented from moving by setting a limiting shell during use, and the threaded rod can be moved to push out the foam by the limiting action of the limiting groove and the limiting block.

[0018] The advantages of the high-temperature hot press for foam production provided by this utility model are as follows:

[0019] With an installation structure, the hot press plate is quickly installed by sliding the T-shaped slider into the T-shaped groove, thereby locking the hot press plate at the bottom of the moving plate. This facilitates the replacement of different models of hot press plates. During the sliding of the T-shaped slider, the pin is squeezed and inserted into the socket under the elastic force of the return spring, fixing the T-shaped slider and further locking it inside the T-shaped groove. This prevents the T-shaped slider from sliding out of the T-shaped groove and causing damage, thus enabling quick loading and unloading of the hot press plate and improving work efficiency.

[0020] With a demolding structure, after hot pressing, the motor drives the shaft to rotate the first bevel gear, which in turn drives the second bevel gear. The rotation of the second bevel gear causes the threaded rod to move under the action of the threaded connection, which in turn drives the limit block to slide inside the limit groove. This causes the threaded rod to drive the push plate to move upward and push the foam inside the mold outward, thus having an automatic material discharge function and improving work efficiency.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 The present invention provides a high-temperature hot press for foam production, comprising a housing 1 and an installation structure 3.

[0029] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the interior of the housing 1 is provided with a processing cavity 2. An installation structure 3 is fixed inside the processing cavity 2. The installation structure 3 includes a hydraulic rod 301 fixed to the top of the housing 1. A movable plate 302 is fixed to the output end of the hydraulic rod 301 inside the processing cavity 2. Guide rods 303 are fixed at the edges inside the processing cavity 2. A guide hole 304 is provided inside the movable plate 302 outside the guide rod 303. A shock-absorbing sleeve 305 is fitted on the outer side of the bottom end of the guide rod 303. An installation plate 306 is installed at the bottom end of the movable plate 302. A hot press plate 307 is fixed to the bottom end of the installation plate 306. T-shaped grooves 308 are fixed on both sides of the top end of the installation plate 306. T-shaped sliders 309 are provided inside the movable plate 302 outside the T-shaped grooves 308. A fixing shell 310 is fixed on both sides of the top end of the movable plate 302. The internal part of the plate 306 is equipped with a pin 311, and a return spring 312 is installed on the outside of the pin 311. A return plate 313 is fixed to the outside of the pin 311 at the bottom of the return spring 312. The T-shaped slider 309 on the outside of the pin 311 has a socket 314 inside. A moving block 315 is fixed to the top of the pin 311. The guide rods 303 are evenly distributed inside the processing cavity 2. The two ends of the guide rods 303 are fixedly connected to the two ends inside the processing cavity 2. The shock-absorbing sleeve 305 is made of sponge material. The T-shaped sliders 309 are symmetrically distributed at the top of the mounting plate 306. The T-shaped sliders 309 and the moving plate 302 are slidably connected through the T-shaped groove 308. The pin 311 and the return plate 313 are telescopically connected through the return spring 312. The T-shaped sliders 309 and the pin 311 are engaged through the socket 314.

[0030] By sliding the T-shaped slider 309 into the T-shaped groove 308, the hot press plate 307 can be quickly installed, thus easily locking the hot press plate 307 at the bottom of the moving plate 302. This facilitates the replacement of different models of hot press plates 307. Simultaneously, as the T-shaped slider 309 slides in, it presses the pin 311, causing the pin 311 to move upwards and compress the reset plate 313, which in turn compresses the reset spring 312. When one side of the T-shaped slider 309 abuts against one side inside the T-shaped groove 308, the reset plate 313 resets under the elastic force of the reset spring 312, inserting the pin 311. The T-shaped slider 309 is fixed inside the insertion hole 314, thereby further locking the T-shaped slider 309 inside the T-shaped groove 308, preventing the T-shaped slider 309 from sliding out of the T-shaped groove 308 and causing damage. Then, by activating the hydraulic rod 301, the moving plate 302 is driven to slide outside the guide rod 303 through the guide hole 304, which facilitates the hot pressing work. In addition, by setting the shock-absorbing sleeve 305, which is made of sponge material, it plays a role in buffering and shock absorption for the hot pressing plate 307 during the hot pressing process, thereby effectively protecting the hot pressing plate 307.

[0031] Reference Figures 2-4 As shown, a mold 4 is installed at the top of the processing cavity 2. A demolding structure 5 is provided inside the bottom box 1 of the mold 4. The demolding structure 5 includes an inner cavity 501 located inside the bottom box 1 of the processing cavity 2. A motor 502 is fixed to one side inside the inner cavity 501. A rotating shaft 503 is fixed to the output end of the motor 502. A first bevel gear 504 is fixed to one end of the rotating shaft 503. A second bevel gear 505 is installed on one side of the first bevel gear 504. A limit shell 506 is fixed inside the inner cavity 501 at the top of the second bevel gear 505. A threaded rod 507 is installed inside the second bevel gear 505. A threaded rod 507 is located inside the outer box 1 of the outer side of the threaded rod 507. There is a through hole 508. The top of the internal cavity 501 on both sides of the threaded rod 507 is provided with a limiting groove 509. The limiting groove 509 is used to fix the limiting blocks 510 on both sides of the threaded rod 507. The top of the threaded rod 507 is fixed with a push plate 511. The outer side of the push plate 511 is provided with a reserved groove 512 inside the housing 1. The first bevel gear 504 and the second bevel gear 505 are meshed. The threaded rod 507 is threadedly connected to the second bevel gear 505. The limiting blocks 510 are symmetrically distributed on both sides of the threaded rod 507. The top of the threaded rod 507 extends through the interior of the limiting shell 506 to the interior of the reserved groove 512 and is fixedly connected to the bottom of the push plate 511.

[0032] After hot pressing is completed, the motor 502 drives the rotating shaft 503 to rotate the first bevel gear 504, which in turn drives the second bevel gear 505 to rotate. By setting a limiting shell 506 to prevent the second bevel gear 505 from moving, and by setting a limiting groove 509 and a limiting block 510 to limit the movement, the rotation of the second bevel gear 505 can ensure that the threaded rod 507 moves under the action of the threaded connection, thereby driving the limiting block 510 to slide inside the limiting groove 509. This causes the threaded rod 507 to drive the push plate 511 to move upward and push the foam inside the mold 4 outward, which has an automatic material discharge function, thereby improving work efficiency.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
