Description

Technical Field

[0001] This utility model relates to the technical field of automotive sound-absorbing cotton processing equipment, and in particular to a molding and cutting equipment for automotive sound-absorbing cotton production. Background Technology

[0002] Automotive sound-absorbing cotton absorbs noise generated during vehicle operation by converting it into heat energy through the fine denier fibers inside the cotton, thus achieving the function of sound absorption and noise reduction. In the production and processing of automotive sound-absorbing cotton, it is necessary to hot-press the cotton into shape, and then cut off the excess scraps for edge trimming.

[0003] The existing announcement number is CN211440297U, entitled "A punching and forming device for automotive sound-absorbing cotton." It includes a worktable, a bracket fixedly connected above the worktable, a support plate fixedly connected to the top of the bracket, cylinders mounted on both sides of the support plate, a connecting plate fixedly connected to the output end of the cylinders below, an electric heating plate fixedly connected to the lower end of the connecting plate, an iron plate fixedly connected to the lower end of the electric heating plate, blades movably connected to both sides of the iron plate, an oiled wood board fixedly connected between the blades and at the bottom of the iron plate, and lead screws on both sides of the worktable, with adjusting screws threaded onto the lead screws. The upper end of the adjusting nut is fixedly connected to a suction fan. A waste bin is located at the bottom of the workbench. Slots are provided below the lead screw and on both sides of the workbench. Sliders are slidably connected to the slides within the slots. A hose is fixedly connected to the input end of the suction fan, and the suction fan is connected to the sliders through the hose. A heat-conducting iron plate is added to the back of the oiled wood board to ensure that the oiled wood board and the blade are heated evenly. This effectively avoids uneven heating of the mold blade and the oiled wood board, which would result in poor sealing of the sound-absorbing cotton. As a result, the sealing effect is good, the edges of the sound-absorbing cotton do not crack, and the mold has a long service life.

[0004] However, the above-mentioned method of removing scraps from automotive sound-absorbing cotton by hot pressing uses a blade to run around the forming mold to cut and remove the scraps. This cutting method requires the blade to run around the forming mold once to complete the cutting, resulting in low cutting efficiency. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes a molding and cutting equipment for the production of automotive sound-absorbing cotton.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a molding and cutting device for producing automotive sound-absorbing cotton, comprising an installation component, a sliding frame, a lower mold, and an upper mold. The installation component includes an installation frame base, on the top surface of which the lower mold is assembled, and on the top surface of which the sliding frame is vertically fixed, the upper mold is vertically arranged in the sliding frame, and on the top surface of which a hydraulic rod is vertically fixed, with the output end of the hydraulic rod fixed to the top surface of the upper mold. A knife groove frame is horizontally sleeved on the outer side of the lower mold, and a knife frame is horizontally sleeved on the outer side of the upper mold, with a cutting blade vertically fixed on the bottom surface of the knife frame, and the cutting blade of the knife frame is inserted into the knife groove at the top of the knife groove frame.

[0007] As a preferred option, locking bolts are installed through the horizontal threads on both sides of the mounting frame, and threaded grooves are opened horizontally on both sides of the bottom of the lower mold, and the threaded grooves are threadedly assembled and connected with the locking bolts.

[0008] As a preferred embodiment, a slider is horizontally fixed on the top surface of the upper mold, and the slider is vertically slidably assembled and connected to the slide frame.

[0009] As a preferred embodiment, a pin is vertically fixed on the bottom surface of the tool slot frame, and a sleeve is vertically slidably fitted on the pin.

[0010] As a preferred embodiment, the bottom end of the sleeve is fixed to the top surface of the mounting frame, and a first spring is vertically fixed to the top surface of the sleeve, with the top end of the first spring fixed to the bottom surface of the tool slot frame.

[0011] As a preferred embodiment, a hole frame is vertically fixed on the top surface of the die frame, and a sliding column is vertically slidably inserted into the hole frame, with the top end of the sliding column fixed on the top surface of the upper die.

[0012] As a preferred embodiment, a second spring is vertically sleeved on the lower side of the slide column, and the two ends of the second spring are fixed to the bottom end of the slide column and the hole frame, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the lower mold is inserted into the mounting frame of the mounting component, and the lower mold is fixedly assembled in the mounting frame by locking bolts. During molding, the hydraulic rod on the sliding frame is activated to push the upper mold downward, and the automotive sound-absorbing cotton is hot-pressed and molded. Then, when the lower mold and the upper mold are closed, the knife frame on the upper mold cuts the automotive sound-absorbing cotton downward, and squeezes the automotive sound-absorbing cotton into the knife groove frame of the lower mold, thus cutting and separating the automotive sound-absorbing cotton. Therefore, when the lower mold and the upper mold are closed, the cutting blades of the knife groove frame and the knife frame are used to cut the automotive sound-absorbing cotton in one piece, thereby improving the cutting efficiency.

[0026] like Figures 1 to 5 As shown, a molding and cutting device for producing automotive sound-absorbing cotton includes a mounting component 1, a sliding frame 2, a lower mold 3, and an upper mold 4. The mounting component 1 includes a mounting frame 11, on which the lower mold 3 is assembled. The sliding frame 2 is vertically fixed on the top surface of the mounting frame 11. The upper mold 4 is vertically arranged in the sliding frame 2, and a hydraulic rod 21 is vertically fixed on the top surface of the sliding frame 2. The output end of the hydraulic rod 21 is fixed on the top surface of the upper mold 4. A knife groove frame 32 is horizontally sleeved on the outer side of the lower mold 3, and a knife frame 42 is horizontally sleeved on the outer side of the upper mold 4. A cutting blade is vertically fixed on the bottom surface of the knife frame 42, and the cutting blade of the knife frame 42 is inserted into the knife groove at the top of the knife groove frame 32. Locking bolts 12 are horizontally threaded through the middle of both sides of the mounting frame 11. Water is installed at the bottom of both sides of the lower mold 3. The upper mold 4 has a threaded groove 31, which is threadedly connected to the locking bolt 12. A slide bar 41 is horizontally fixed on the top surface of the upper mold 4, and the slide bar 41 is vertically slidably connected to the slide frame 2. In use, the lower mold 3 is inserted into the mounting frame 11 of the mounting part 1. The lower mold 3 is fixedly assembled in the mounting frame 11 by the locking bolt 12. When forming, the hydraulic rod 21 on the slide frame 2 is activated to push the upper mold 4 downward to hot-press and form the automotive sound-absorbing cotton. Then, when the lower mold 3 and the upper mold 4 are closed, the knife frame 42 on the upper mold 4 cuts the automotive sound-absorbing cotton downward and squeezes the automotive sound-absorbing cotton into the knife groove frame 32 of the lower mold 3, cutting and separating the automotive sound-absorbing cotton. Thus, when the lower mold 3 and the upper mold 4 are closed, the cutting blades of the knife groove frame 32 and the knife frame 42 separate the automotive sound-absorbing cotton in one piece, thereby improving the cutting efficiency.

[0027] In one embodiment, such as Figure 4 As shown, a post 34 is vertically fixed on the bottom surface of the knife groove frame 32, and a sleeve 33 is vertically slidably fitted on the post 34. The bottom end of the sleeve 33 is fixed on the top surface of the mounting frame 11, and a first spring 35 is vertically fixed on the top surface of the sleeve 33. The top end of the first spring 35 is fixed on the bottom surface of the knife groove frame 32. During cutting, the knife groove frame 32 causes the post 34 to slide vertically in the sleeve 33. The vertical sliding of the post 34 in the sleeve 33 compresses the first spring 35, effectively ensuring the effectiveness of the knife groove frame 32 in cutting automotive sound-absorbing cotton.

[0028] In one embodiment, such as Figure 5 As shown, a hole frame 43 is vertically fixed on the top surface of the cutter frame 42, and a sliding column 44 is vertically slidably inserted through the hole frame 43. The top end of the sliding column 44 is fixed on the top surface of the upper mold 4. A second spring 45 is vertically sleeved on the lower side of the sliding column 44, and the two ends of the second spring 45 are respectively fixed on the bottom end of the sliding column 44 and the hole frame 43. During cutting, the cutter frame 42 causes the sliding column 44 to slide vertically in the hole frame 43. The sliding column 44 squeezes the second spring 45 by sliding vertically in the hole frame 43, which effectively ensures the effectiveness of the cutter frame 42 in cutting automotive sound-absorbing cotton.

[0029] In this embodiment, the lower mold 3 is inserted into the mounting frame 11 of the mounting component 1 during use. The lower mold 3 is fixedly assembled in the mounting frame 11 by locking bolts 12. During molding, the hydraulic rod 21 on the sliding frame 2 is activated to push the upper mold 4 downward to hot-press and mold the automotive sound-absorbing cotton. Then, when the lower mold 3 and the upper mold 4 are closed, the knife frame 42 on the upper mold 4 cuts the automotive sound-absorbing cotton downward and squeezes the automotive sound-absorbing cotton into the knife groove frame 32 of the lower mold 3, cutting and separating the automotive sound-absorbing cotton. Thus, when the lower mold 3 and the upper mold 4 are closed, the cutting blades of the knife groove frame 32 and the knife frame 42 separate the automotive sound-absorbing cotton as a whole.

[0030] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
