[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] Embodiment 1:

[0027] A composite hot-pressing forming device for environmentally friendly automobile interior decoration parts comprises a support box 1, an operating table 2, a back support frame 3 and a side support plate 6. The upper end surface of the support box 1 is fixedly connected to the operating table 2, which supports the support box. The back support frame 3 is fixedly connected to the rear side of the upper end surface of the operating table 2. The back support frame 3 is L-shaped. The L-shaped back support frame 3 supports an electric hydraulic push rod 56, an air guide tube 44 and an electric motor 47 respectively. The side support plate 6 is fixedly connected to the left side of the upper end surface of the operating table 2, which supports a multi-stage electric push rod 42 and an exhaust fan 57 respectively. A storage partition 11 is fixedly connected to the inside of the support box 1, and the storage partition 11 divides the internal space of the support box 1 so that the staff can classify and store the processing items. A box door is installed on the front end surface of the support box 1. The box door is an openable and closable structure, and the openable and closable box door blocks the opening of the front end surface of the support box 1.

[0028] A hot pressing assembly 5 for hot pressing and forming external automobile interior parts is arranged on the left side of the upper end surface of the operating table 2, and a cooling assembly 4 for blowing air to the hot pressing assembly 5 is arranged on the right side of the inner wall of the back support frame 3, so as to further improve the forming efficiency of the external automobile interior parts. A control panel is installed on the right side of the upper end surface of the operating table 2, and the control panel is connected to the electric hydraulic push rod 56, the motor 47 and the exhaust fan 57 through wires, and the control panel facilitates the staff to control the electric hydraulic push rod 56, the motor 47 and the exhaust fan 57 respectively. A temperature controller is installed on the left side of the upper end surface of the operating table 2, and the temperature controller is connected to the heating plate 54 through wires, and the temperature controller facilitates the staff to control the heating plate 54 to work according to the preset temperature value. Since the internal detailed structure and working principle of the control panel and the temperature controller are relatively mature technologies in the prior art, they will not be described in detail here.

[0029] The hot pressing assembly 5 includes an upper mold body 51, a heat conducting plate 52, a lower mold body 53, a heating plate 54, an embedding cavity 55 and an electric hydraulic push rod 56. An electric hydraulic push rod 56 is installed on the left side of the inner wall of the back support frame 3. The electric hydraulic push rod 56 will drive the upper mold body 51 to move up and down when working. The upper mold body 51 is installed on the lower end of the electric hydraulic push rod 56. The lower end surface of the upper mold body 51 is fitted with the lower mold body 53. The upper mold body 51 matches the lower mold body 53. The upper mold body 51 and the lower mold body 53 are convenient for pressing raw materials into required external automotive interior parts. The lower end surface of the upper mold body 51 and the inner wall of the lower mold body 53 are sprayed with high-temperature non-stick coating. The high-temperature non-stick coating has high hardness, impact resistance and good non-stick properties, which prevents the external automotive interior parts after hot pressing from easily adhering to the lower end surface of the upper mold body 51 or the inner wall of the lower mold body 53. An embedding cavity 55 is opened on the left side of the upper end surface of the operating table 2, and the upper end surface of the embedding cavity 55 is installed with a heat conducting plate 52.

[0030] A heating plate 54 is installed on the lower end surface of the heat conducting plate 52. The material of the heating plate 54 is a carbon fiber electric heating plate. The area of ​​the heating plate 54 is larger than the bottom area of ​​the lower mold body 53. The heating plate 54 made of the carbon fiber electric heating plate is energy-saving, electricity-saving and fast in heating. When working, the heat conducting plate 52 can be quickly heated to the required temperature so that the heat conducting plate 52 can heat the lower mold body 53. The inner wall of the embedded cavity 55 is provided with a heat insulating layer 551, and the material of the heat insulating layer 551 is heat insulating cotton. The heat insulating layer 551 made of heat insulating cotton has good heat insulation, which prevents the heat generated by the heating plate 54 from being quickly dissipated to the outside through the embedded cavity 55, thereby ensuring the heating effect of the heating plate 54.

[0031] Guide rods 511 are symmetrically arranged on the left and right sides of the upper end surface of the upper mold body 51, and the guide rods 511 are connected to the upper mold body 51 by welding.

An exhaust fan 57 is installed on the upper side of the left end surface of the side support plate 6, and the outlet of the exhaust fan 57 is connected to the inlet of the external industrial waste gas purifier through a pipeline. A through cavity 58 is opened on the upper side of the inner part of the side support plate 6. When working, the exhaust fan 57 will suck the air around the upper mold body 51 and the lower mold body 53 through the through cavity 58 and send it into the external industrial waste gas purifier for purification, so as to prevent the harmful gases generated during the hot pressing process from floating in the surroundings to pollute the environment and affect the health of the surrounding workers, making the device more environmentally friendly.

[0032] Embodiment 2:

[0033] On the basis of Example 1, in this embodiment, the multi-stage electric push rod 42 is controlled to drive the lower mold body 53 to move to the right through the linkage rod 49. When the lower mold body 53 moves to the right, the motor 47 drives the fan blades 46 to rotate, so that the rotating fan blades 46 blow air downward to quickly cool down the external automobile interior parts formed in the lower mold body 53 below, thereby improving the processing efficiency of the device, and the left baffle 41 and the right baffle 43 will block and limit the left and right movement range of the lower mold body 53 to prevent the lower mold body 53 from moving excessively to the left or right.

[0034] The cooling component 4 includes a left baffle 41, a multi-stage electric push rod 42, a right baffle 43, an air guide tube 44, a blowing fan blade 46 and a motor 47. The left baffle 41 is fixedly connected to the left side of the upper end surface of the heat conducting plate 52, and the left baffle 41 will block and limit the leftward movement range of the lower mold body 53 to prevent the lower mold body 53 from moving too far to the left. The right side of the upper end surface of the operating table 2 is fixedly connected to the right side of the upper end surface of the operating table 2, and the right baffle 43 will block and limit the rightward movement range of the lower mold body 53 to prevent the lower mold body 53 from moving too far to the right. An air guide tube 44 is installed on the right side of the inner wall of the back support frame 3, and the air guide tube 44 will shield the motor 47 and the blowing fan blade 46. A motor 47 is installed inside the air guide tube 44, and a blowing fan blade 46 is installed at the lower end of the motor 47. When the motor 47 is working, it will drive the blowing fan blade 46 to rotate, so that the rotating blowing fan blade 46 blows air downward to quickly cool down the lower mold body 53 below.

[0035] A linkage rod 49 is arranged in the middle position of the left end face of the lower mold body 53, and the linkage rod 49 is connected to the lower mold body 53 by welding. A multi-stage electric push rod 42 is installed at the left end of the linkage rod 49, and the linkage rod 49 facilitates the multi-stage electric push rod 42 to drive the lower mold body 53 to move left and right. A protective mesh plate 441 is installed at the lower end face of the air guide tube 44, and the protective mesh plate 441 will protect the lower end of the air guide tube 44, so as to ensure the safety of the use of this device. An air inlet cavity 48 is opened on the right side of the upper end face of the back support frame 3, and the air inlet cavity 48 facilitates the external air to enter the interior of the air guide tube 44. An air filter screen plate 45 is installed at the upper end of the air inlet cavity 48, and the air filter screen plate 45 is made of a non-woven filter screen. The air filter screen plate 45 made of a non-woven filter screen will filter and purify the air entering the air inlet cavity 48, so as to avoid the external automobile interior parts after hot pressing molding inside the lower mold body 53 from adhering to a large amount of dust during the cooling process to cause secondary pollution.

[0036] Working principle: During the hot pressing process of external automobile interior parts, the staff first controls the heating plate 54 to work according to the preset temperature value through the temperature controller, so that the heating plate 54 heats the heat conducting plate 52, and the heat conducting plate 52 heats the lower mold body 53. In this process, it is necessary to measure the temperature of the lower mold body 53 at intervals with the help of an external thermometer. When the lower mold body 53 is heated to the required temperature, the electric hydraulic push rod 56 is controlled by the control panel to perform a contraction action, so that the electric hydraulic push rod 56 drives the upper mold body 51 to move upward. When the upper mold body 51 rises to an appropriate height, the composite raw materials required for hot pressing molding can be poured into the lower mold body 53 for heating. When heated to the required state, the upper mold body 51 is controlled by the electric hydraulic push rod 56 to move downward and close the mold with the lower mold body 53 (reference Figure 1 or Figure 3), so as to hot-press the composite raw material inside the lower mold body 53 and maintain the pressure. At the same time, start the exhaust fan 57, so that the exhaust fan 57 sucks the air around the upper mold body 51 and the lower mold body 53 through the through cavity 58 and sends it to the outside industrial waste gas purifier for purification, so as to avoid the harmful gases generated in the hot pressing process from floating around and polluting the environment and affecting the health of the surrounding workers; after maintaining the pressure for the required time, control the electric hydraulic push rod 56 to drive the upper mold body 51 to move upward to the original position, and then control the multi-stage electric push rod 42 to extend, so that the multi-stage electric push rod 42 can drive the lower mold body 53 to move to the right through the linkage rod 49, and move it until the lower mold body 53 fits with the right baffle 43 (reference Figure 2 or Figure 5 ), at this time, the staff can start the motor 47 through the control panel, so that the motor 47 drives the fan blades 46 to rotate, so that the rotating fan blades 46 blow air downward to quickly cool down the external automobile interior parts formed in the lower mold body 53 below. According to the principle of thermal expansion and contraction, the cooled external automobile interior parts will shrink and create a gap with the lower mold body 53, so that the staff can take out the external automobile interior parts in the lower mold body 53; when the external automobile interior parts are taken out, the lower mold body 53 is driven to move to the left by the multi-stage electric push rod 42 and fit with the left baffle 41, and then the motor 47 is turned off and the above operation is repeated to process the next group of external automobile interior parts.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
