[0002] In the processing technology of products such as automotive floor mats and seat cushions, hot pressing equipment is required. The upper and lower molds are used for pressing, so that multiple layers of materials are pressed together. When producing different types of products, due to the different structural shapes of different interior trims, the molds need to be replaced. Generally, manual operation is mainly used for mold replacement, so it takes a certain amount of time. Since the current hot pressing device generally has a single mold arranged under the hot pressing mechanism, during the replacement process, the hot pressing device generally stops running. Moreover, during the loading and unloading process of the single mold, the hot pressing device is also in a stopped state, which to a certain extent affects the production efficiency of the products. Summary of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the utility model provides a hot pressing device, which can facilitate the loading and unloading and mold replacement, thereby improving the production efficiency of products.

[0004] According to an embodiment of the utility model, a hot pressing device includes a platform, two groups of support mechanisms fixedly arranged on the platform, and a hot pressing mechanism fixed on the top of the support mechanisms. A linear guide rail is arranged on the platform between the two groups of support mechanisms. Two sliding seats are slidably arranged on the linear guide rail. A hot pressing mold is detachably connected to each sliding seat. A first positioning mechanism is arranged on the platform below the hot pressing mechanism and cooperating with the sliding seats. The two ends of the linear guide rail extend to the outside of the support mechanisms. The length of the linear guide rail at the part outside the two groups of support mechanisms is not less than the length of the sliding seats. Second positioning mechanisms cooperating with the sliding seats are arranged at the two ends of the linear guide rail.

[0005] Preferably, a guiding member is connected to the top of the sliding seat, the guiding member is connected to a mounting seat, and the hot pressing mold is detachably connected to the mounting seat.

[0017] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.

[0018] As shown in Figure 1 , a hot pressing device includes a platform 1, two sets of support mechanisms 2 fixedly arranged on the platform 1, and a hot pressing mechanism 3 fixed on the top of the support mechanisms 2. A linear guide rail 4 is arranged on the platform 1 between the two sets of support mechanisms 2. Two sliders 5 are slidably arranged on the linear guide rail 4. A linear motor cooperating with the linear guide rail 4 is arranged in the slider 5. A hot pressing die 6 is detachably connected to each slider 5. A first positioning mechanism 7 is arranged on the platform 1 below the hot pressing mechanism 3 and cooperating with the slider 5. Both ends of the linear guide rail 4 extend to the outside of the support mechanism 2. The length of the linear guide rail 4 at the part outside the two sets of support mechanisms 2 is not less than the length of the slider 5. Second positioning mechanisms 8 cooperating with the slider 5 are arranged at both ends of the linear guide rail 4;

[0019] The hot pressing die 6 can slide on the linear guide rail 4 along with the slider 5. Since two sliders 5 are provided and a hot pressing die 6 can be detachably connected to each slider 5, during the process of removing the die and discharging the material after hot pressing, another hot pressing die 6 can still perform hot pressing work. And when it is necessary to replace the hot pressing die 6, during the replacement process, another hot pressing die 6 can still perform hot pressing work;

[0020] In order to facilitate the quick switching of the working states of the two sliders 5, as shown in Figure 2 , in a further embodiment, a guide member 510 is connected to the top of the slider 5, the guide member 510 is connected to a mounting seat 520, and the hot pressing die 6 is detachably connected to the mounting seat 520. The guiding direction of the guide member 510 and the moving direction of the hot pressing mechanism 3 are both perpendicular to the platform 1. The mounting seat 520 is connected to the slider 5 through an elastic member 530;

[0021] Under the action of the guide member 510, the vertical movement route of the mounting seat 520 at the top of the slider 5 is restricted. When the mounting seat 520 moves downward, it overcomes the elastic force of the elastic member 530 and enables the first positioning mechanism 7 to act, so that the positions of the slider 5 and the mounting seat 520 are fixed. When the first positioning mechanism 7 no longer acts, under the action of the elastic member 530, the mounting seat 520 resets and the slider 5 can slide freely;

[0022] Specifically, the first positioning mechanism 7 includes a positioning rod 701 fixedly connected to the bottom of the mounting seat 520 and parallel to the guiding direction of the guide member 510, and a positioning hole 702 arranged on the platform 1. First magnetic attraction components 710 are also arranged at the bottom end of the positioning rod 701 and the bottom of the positioning hole 702;

[0023] In this embodiment, the elastic member 530 is a rigid spring. When the hot pressing mechanism 3 presses down the mounting seat 520, the positioning rod 701 enters the positioning hole 702, and the first magnetic attraction assembly 710 takes effect, so that the positioning rod 701 does not leave the positioning hole 702 to achieve the positioning effect;

[0024] In order to facilitate the positioning rod 701 to enter the positioning hole 702, in a further embodiment, the first magnetic attraction assembly 710 includes a hemispherical magnetic attraction head 711 fixed to the bottom end of the positioning rod 701 and a magnetic attraction seat 712 fixed to the bottom of the positioning hole 702. A magnetic attraction groove 713 with a spherical plate shape is provided on the magnetic attraction seat 712;

[0025] Specifically, the guiding member 510 includes a guiding hole 511 provided at the top of the sliding seat 5 and a guiding rod 512 movably arranged in the guiding hole 511. The bottom of the guiding rod 512 is connected to the bottom of the guiding hole 511 through the elastic member 530, and the top of the guiding rod 512 is fixedly connected with the mounting seat 520;

[0026] In order to limit the movement route of the sliding seat 5, in a further embodiment, the second positioning mechanism 8 includes positioning seats 801 fixed at both ends of the linear guide rail 4. A second magnetic attraction assembly 810 is provided between the opposite sides of the two sliding seats 5 and the corresponding positioning seats 801. The positioning seat 801 can block the sliding of the sliding seat 5. After the sliding seat 5 approaches the positioning seat 801, it can be adsorbed to the positioning seat 801 through the second magnetic attraction assembly 810;

[0027] In order to facilitate the control of the moving distance of the sliding seat 5, in a further embodiment, a distance sensor 802 is further provided between the opposite sides of the two sliding seats 5 and the corresponding positioning seats 801. The transmitting end and the receiving end of the distance sensor 802 are respectively arranged on the positioning seat 801 and the sliding seat 5.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
