Description

[0002] In the current automobile interior molding technology, heating molding is an indispensable process, and the heating molding process of automobile interiors cannot be separated from the molding machine. For example, during the heating molding process, the carpet nail frame of the car is usually placed on the lifting mechanism in the heating molding machine, and the lifting mechanism is used to lift or lower the carpet nail frame, so that the heated and molded carpet nail frame can be sent out of the molding machine in time, and the carpet nail frame to be heated and molded can be connected to the heating molding machine.

[0003] When the car carpet is heat-formed, the original carpet needs to be placed on a nail frame, the nails on the nail frame are passed through the original carpet, and then the upright cotton is covered on the original carpet. The nail frame is driven up and down by a lifting mechanism to perform hot pressing molding. The lifting mechanism is driven by a hydraulic rod, but when the upright cotton is covered on the original carpet, a small amount of cotton wool will float in the air and adhere to the surface of the telescopic end of the hydraulic rod. When the telescopic end of the hydraulic rod is contracted, the cotton wool is easy to enter the inner cavity of the hydraulic rod, thereby affecting the service life of the hydraulic rod.

[0032] Example 1: Please refer to Figure 1-Figure 9 The present invention provides a technical solution: a nail frame lifting mechanism of a car carpet heating molding mold, comprising a guide rail 1, the number of the guide rails 1 is two, the surface of the guide rail 1 is slidably connected with a guide block 11, the top of the guide block 11 is fixedly connected with a support plate 12, the top of the support plate 12 is fixedly connected with a hydraulic rod 13, the top of the hydraulic rod 13 is fixedly connected with a connecting plate 14, the top of the support plate 12 is provided with a guide mechanism 2, the surface of the hydraulic rod 13 is provided with a processing mechanism 3 used in conjunction with the telescopic end of the hydraulic rod 13, and the processing mechanism 3 is used in conjunction with the guide mechanism 2.

[0033] The guide mechanism 2 includes a guide cylinder 201 fixedly connected to the top of the support plate 12, the inner cavity of the guide cylinder 201 is slidably connected to two moving rods 202, the top of the moving rod 202 is fixedly connected to a mounting plate 203, the mounting plate 203 is used to connect with the carpet nail frame, one side of the moving rod 202 is provided with a guide groove 204, the inner cavity of the guide groove 204 is slidably connected to an adjusting rod 205, one side of the guide cylinder 201 is fixedly connected to a limiting rod 206, one side of the limiting rod 206 and one side of the guide cylinder 201 are provided with an adjusting hole 207 used in conjunction with the adjusting rod 205, one side of the guide groove 204 is fixedly connected to a limiting assembly, the limiting assembly is used to adjust the adjusting rod 20 5 is used for auxiliary guiding. By setting the guiding mechanism 2, when the car carpet is formed, the nail frame is installed on the top of the mounting plate 203, and then the original carpet is installed on the top of the nail frame. At this time, the upright cotton is covered on the original carpet, and the hydraulic rod 13 is started by the external control switch, so that the hydraulic rod 13 drives the moving rod 202 to move in the inner cavity of the guide cylinder 201, thereby achieving the effect of guiding the movement of the mounting plate 203. When the moving rod 202 moves in the guide cylinder 201, the adjusting rod 205 moves in the inner cavity of the guide groove 204. Through the setting of the guide groove 204, the adjusting rod 205 moves horizontally in the adjusting hole 207.

[0034] The limiting assembly includes a clamping rod 208 rotatably connected to one side of the moving rod 202, a positioning rod 209 used in conjunction with the clamping rod 208 is fixedly connected to one side of the moving rod 202, an elastic sheet 210 is fixedly connected to one side of the clamping rod 208, one side of the elastic sheet 210 is fixedly connected to one side of the moving rod 202, the guide groove 204 includes a straight groove 211 and a switching groove 212, the straight groove 211 is connected to the switching groove 212, and the straight groove 211 and the switching groove 212 are both provided on one side of the moving rod 202.

The adjusting rod 205 is moved horizontally in the adjusting hole 207 by setting the guide groove 204, and the adjusting rod 205 is blocked by the clamping rod 208, so that when the moving rod 202 moves upward, the adjusting rod 205 moves in the straight groove 211, and when the moving rod 202 moves downward, the adjusting rod 205 enters the inner cavity of the switching groove 212 under the blocking of the clamping rod 208. At this time, the two adjusting rods 205 will move to the opposite side, thereby achieving the effect of adjusting the position of the adjusting rod 205.

When the telescopic end of the hydraulic rod 13 contracts, the scraper 3105 can scrape off the cotton wool on the surface of the telescopic end of the hydraulic rod 13, thereby reducing the cotton wool from entering the interior of the hydraulic rod 13. By setting the half gear 3106 and the tooth plate 3107 for coordinated use, when the two arc blocks 3104 are moved to the opposite side, since the half gear 3106 and the tooth plate 3107 are in a meshing state, when the arc block 3104 moves, the half gear 3106 will rotate, thereby causing the arc block 3104 to rotate ninety degrees.

When the telescopic end of the hydraulic rod 13 contracts, the cotton wool on the surface of the telescopic end of the hydraulic rod 13 can be scraped off by the scraper strip 3105, thereby reducing the cotton wool from entering the interior of the hydraulic rod 13. When the arc block 3104 and the processing block 3103 are in a vertical state, the surface of the sponge belt 3111 contacts the scraper strip 3105. 5, at this time, the micro motor 3112 is started by using an external control switch to make the mesh belt 3110 drive, so that the sponge belt 3111 removes the dust and cotton wool on the surface of the scraper strip 3105, and a small amount of water is transported to the sponge belt 3111 through an external water transport device, and then the sponge belt 3111 is squeezed by the squeezing plate 3115, so that the water in the sponge belt 3111 is squeezed out, and the water with a small amount of cotton wool is transported to the inner cavity of the water collecting shell 3113 and the water guide pipe 3114 and enters the water receiving shell 3116, so as to achieve the effect of collecting water.
