Description

Technical Field

[0001] The invention relates to the technical field of injection molding, in particular to a leather-like material processing technology and equipment. Background Art

[0002] In order to improve the decorative effect, some three-dimensional components will be designed with leather patterns on the surface to form an imitation leather appearance. For example, some interior shell parts in automobiles, and because the leather patterns are directly set on the three-dimensional surface, such imitation leather shell parts are partially made by injection molding. During injection molding, when the structure of the molded shell part is complex, the injection pressure of the material will be increased accordingly to avoid the formation of cavities. Higher injection pressure will increase the probability of excess material entering between the two mating surfaces of the mold. The residue remaining on the mating surface will easily interfere with the mold during the secondary mold closing, resulting in an increase in the gap between the two mating surfaces, affecting molding and being unfavorable for continuous production.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0024] In specific implementation, when the seat plate 210 moves backward, the fixed rod 440 pulls one end of the push rod 450 to move away from the fixed mold 100, so that the other end of the fixed rod 440 moves toward the mold surface 110, so that the mold surface 110 drives the cleaning rod 420 to slide along the two inclined rails 411 of the corresponding group, so that the two cleaning rods 420 move to the right and away from each other, and the two cleaning rods 430 move to the left and move toward the middle, so that the cleaning rod 1 420 and the cleaning rod 2 430 each clean a triangular area on the mold surface 110, thereby realizing the overall cleaning of the mold surface 110, avoiding residual material from remaining on the mold surface 110 and affecting the subsequent mold closing between the fixed mold 100 and the peripheral mold 220.
