Description

Technical Field

[0001] The present invention relates to a shaping die-cutting machine and a using method for a cavity EVA sound insulation and sealing device, belonging to the technical field of plastic molding. Background Art

[0002] Since vehicles travel on various roads and tracks outdoors, they will generate vibrations, resonances, resonances, and noises under the influence of various conditions on the road surface. For example, cars, electric vehicles, high-speed rails, subways, and aircraft hulls have various cavities, and high-speed airflows will be generated in the bypass cavities of the vehicle body during high-speed driving, which will bring strong noises and vibrations to passengers and drivers.

[0003] The prior art generally uses a two-injection molding process to form a sound insulation device. Its production process is that the mold of the skeleton injects nylon 66 into a nylon skeleton, and then it is placed in an injection molding EVA mold for injection molding to produce a finished product. Both are completed by two single machines. The two processing processes require two molds, and the molds require high precision and cannot expand or leak materials. Therefore, the investment is large, the mold production cycle is long, the injection molding process is complex, the efficiency is low, the scrap rate is high, and the cost is high. Summary of the Invention

[0004] In view of the deficiencies of the prior art in the two processing processes, such as large investment, long mold production cycle, complex injection molding process, and high cost, the present invention provides a shaping die-cutting machine and a using method for a cavity EVA sound insulation and sealing device, which can continuously shape and die-cut to produce a formed product at one time, with simple processing and greatly improved production efficiency.

[0005] The technical solution adopted by the present invention to achieve the above object is: a shaping die-cutting machine for a cavity EVA sound insulation and sealing device. In the U-shaped groove I of the shaping die-cutting machine frame, a die-cutting device and a die-cutting knife device are successively arranged. A buffer rubber pad is respectively arranged between the needle roller bearing square slide I on both sides of the die-cutting knife device and the needle roller bearing square slide II on both sides of the die-cutting device. The die-cutting knife gear of the die-cutting knife device meshes with the die-cutting lower roller gear of the die-cutting device; In the U-shaped groove II of the frame, a traction shaping device II and a traction shaping device I are successively arranged. A buffer rubber pad is respectively arranged between the needle roller bearing square slide III on both sides of the traction shaping device I and the needle roller bearing square slide IV on both sides of the traction shaping device II. The traction upper gear of the traction shaping device I meshes with the traction lower gear of the traction shaping device II; The lower ends of the four adjusting bolts screwed to the upper cover of the frame are respectively in contact and cooperation with two needle roller bearing square slides I and two needle roller bearing square slides III, and are used for adjusting the gaps between the die-cutting upper roller of the die-cutting knife device and the die-cutting lower roller of the die-cutting device, and between the traction shaping upper roller of the traction shaping device I and the traction shaping lower roller of the traction shaping device II; The die-cutting frequency-modulated motor connected with the die-cutting motor frequency modulator is connected to the die-cutting lower roller; the traction frequency-modulated motor connected with the traction motor frequency modulator is connected to the traction and shaping lower roller; at least one set of die edges is provided on the die-cutting upper roller.

[0006] A method for using a shaping and die-cutting machine for a cavity EVA sound insulation and sealing device is as follows: Start the traction frequency-modulated motor. The traction frequency-modulated motor drives the traction and shaping lower roller of the traction and shaping device II to rotate. The traction and shaping lower roller cooperates with the traction and shaping upper gear of the traction and shaping device I through the lower traction gear, driving the traction and shaping upper roller to rotate simultaneously. Start the die-cutting frequency-modulated motor. The die-cutting frequency-modulated motor drives the die-cutting lower roller of the die-cutting device to rotate. The die-cutting lower roller cooperates with the die-cutting blade gear of the die-cutting upper roller through the die-cutting lower roller gear, driving the die-cutting upper roller to rotate simultaneously. Feed the EVA semi-finished belt between the traction and shaping upper roller and the traction and shaping lower roller. Adjust the adjusting bolts at the upper ends of the needle roller bearing square slide seats III on both sides of the traction and shaping upper roller clockwise or counterclockwise respectively, so that the gap between the traction and shaping upper roller and the traction and shaping lower roller is less than the thickness of the EVA semi-finished belt. After the adjustment of the two adjusting bolts is completed; The EVA semi-finished belt becomes an EVA finished belt after being shaped by rolling between the traction and shaping upper roller and the traction and shaping lower roller, and the EVA finished belt is pulled between the die-cutting upper roller and the die-cutting lower roller; Adjust the adjusting bolts at the upper ends of the needle roller bearing square slide seats I on both sides of the die-cutting device clockwise or counterclockwise respectively, so that at least one set of die edges on the die-cutting upper roller contacts the die-cutting lower roller. When cutting out at least one set of EVA sound insulation and sealing devices by rolling, the adjustment of the two adjusting bolts is completed; The EVA semi-finished belt passes between the traction and shaping upper roller and the traction and shaping lower roller and between the die-cutting upper roller and the die-cutting lower roller in sequence, realizing the rolling cutting of multiple at least one set of EVA sound insulation and sealing devices, and the waste belt is taken back.

[0007] The beneficial effects produced by the present invention are as follows: The present invention can continuously complete the shaping and rolling cutting of EVA sound insulation and sealing device products at one time, replacing the deficiency of the existing technology of completing the products through two injection molding processes, saving manpower, material resources and costs, and increasing the production efficiency by more than 80%.

[0008] The die edges provided on the die-cutting upper roller of the present invention can be set according to the shape of the cut-out finished product. When the diameters of the die-cutting upper roller and the die-cutting lower roller are the same, only the die-cutting upper roller needs to be replaced to roll cut new finished products, with a simple structure and convenient process.

[0009] The present invention is applied to the production line, improving the production efficiency of finished products from raw materials to finished products. Description of the Drawings
