Lower mold device for automatic mold mounting machine

Abstract

The invention provides a lower mold device for an automatic mold mounting machine and relates to the field of precision mechanical equipment. The lower mold device comprises a bottom plate, a bottom mold, a vacuum absorption mechanism, an embedded cutter set and a cooling waterway. The bottom mold is supported on the bottom plate through a guide column. Air vents are formed in the bottom mold. The vacuum absorption mechanism is arranged on the lower side of the bottom mold. Surface skin is attached to the surface of the bottom mold under the absorption effect of the vacuum absorption mechanism. The embedded cutter set rising from the lower side of the surface skin is arranged on the bottom mold. The embedded cutter set comprises a stainless steel blade and a brass blade. A base plate of an automobile door is covered with the surface skin along the edge of the surface skin through the embedded cutter set. The cooling waterway is wound around the periphery of the bottom mold. By the adoption of the lower mold device, the requirement of the industrial large-batch production of automobiles is met, meanwhile it also can be guaranteed that the planes and the vertical faces of the workpieces are firmly attached, no bubble is generated in the portion between fabric and the base material, and the quality of products is improved greatly.

Description

technical field [0001] The invention relates to the field of precision mechanical equipment, in particular to a lower mold device on an automatic eye-entrying machine. Background technique [0002] The pressing and covering method of the traditional automobile door panel skin is as follows: two sets of power mechanisms drive a set of hemming molds to complete the horizontal and vertical movements to achieve the covering of the door panel skin. Its disadvantage is: since the profile of the car door panel trim is formed by a curved surface, the horizontal position is not the same curved surface as the next level. Therefore, during processing, the profile of a set of molds cannot take into account the two profiles. The hemming mechanism of the automobile door panel skin in the known technology does not have a good hemming effect at this position, and air bubbles are easily generated between the horizontal plane and the skeleton interlayer. If two sets of horizontal and vertic...
