Description

Technical Field

[0001] The invention relates to the technical field of production mechanisms, in particular to a production mechanism and a production method for an automobile inner front enclosure. Background Art

[0002] The car's inner front wall is located in the front part of the cockpit. It is divided into a hard cotton felt layer and a PE + soft cotton felt composite layer. The main process of manufacturing the car's inner front wall is to press these two layers into shape. With the continuous advancement of industrial technology, the technology of the car's inner front wall is also progressing. At present, it is generally changed by changing the shape of the inner front wall surface. The original through-hole wire harness clip is clamped on the sheet metal body structure, and the existing blind hole and wire harness clip are designed on the inner front wall. It has a good barrier effect on the transmission of external sound to the car, and makes the wire harness clip easy to clamp. The production mechanism needs to be used when producing the car's inner front wall; For example, the authorized patent with announcement number CN114454502A (a method for manufacturing the front wall of a car cockpit): the worker takes out the hard cotton felt layer that has been cooled in the shallow cold mold and stacks it on the composite layer in the deep cold mold. The second conveyor belt sends the hard cotton felt layer that has been heated to the shallow cold mold. The press presses the hard cotton felt layer on the shallow cold mold while absorbing part of its heat. At the same time, the press presses the hard cotton felt layer on the shallow cold mold and presses the hard cotton felt layer and the composite layer on the shallow cold mold to obtain the finished product of the front wall of the car cockpit. After the pressing is completed, the worker takes the finished product from the deep cold mold and leaves the hard cotton felt layer in the shallow cold mold for cooling. On the other hand, the first conveyor belt sends the next hard cotton felt layer and the next composite layer to the drying box. The drying box heats the hard cotton felt layer and the composite layer at the same time. Although the above-mentioned prior art is convenient for the production of the front panel of the automobile cockpit, during the production process of the front panel of the automobile, workers manually remove the hard cotton felt layer pressed in the shallow cold mold and put it into the deep cold mold, which increases the workload of the workers, is inefficient and has poor practicality.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) In the production process of the automobile inner front panel, the invention realizes the automatic transfer and pressing of the hard cotton felt layer by integrating the automation design of the shallow cold mold and the deep cold mold, and cooperating with the efficient operation of the linear motor and the clamping mechanism. This not only greatly reduces the workload of workers, but also avoids the inefficiency caused by manual operation.

A method for producing a production mechanism for an inner front wall of an automobile, which is realized based on the production mechanism for an inner front wall of an automobile according to claims 1 to 9, characterized in that: The steps include: S1: When producing the front inner wall of an automobile, driving the upper mold 1 (202) of the shallow cold mold (2) to separate from the lower mold 1 (201), and placing a hard cotton felt layer; S2: Then, the outer side plate (501) of the upper mold 1 (202) is driven to move downward between the lower mold 1 (201) and the upper mold 1 (202), and high-temperature steam is output through the steam pipe (505) to heat the hard cotton felt layer, and then the hard cotton felt layer is pressed; S3: After the hard cotton felt layer is pressed, the lower mold 1 (201) and the upper mold 1 (202) are separated, and the movable module (12) on the lower mold 1 (201) is driven to move downward to expose the edge of the hard cotton felt layer, and then the two sides of the hard cotton felt layer are clamped and lifted by the clamping mechanism (7), and then the hard cotton felt layer is moved to the deep cooling mold (3) by the drive of the linear motor (6); S4: driving the second upper mold (302) of the cryogenic mold (3) to rise and separate from the second lower mold (301), and placing the composite layer; then the clamping mechanism (7) clamps the hard cotton felt layer and moves it to the top of the second lower mold (301) and releases it, so that the hard cotton felt layer and the composite layer are stacked; S5: Then, the outer panel (501) of the second upper mold (302) is driven to move downward between the second lower mold (301) and the second upper mold (302), and high-temperature steam is output through the steam pipe (505) to heat the hard cotton felt layer and the composite layer, and then the hard cotton felt layer and the composite layer of the front inner wall of the automobile are compositely pressed; S6: After the pressing of the inner front wall of the automobile is completed, the inner front wall of the automobile is clamped and moved into the cooling frame (8) for cooling treatment and unloading.
