Problems solved by technology

[0003] The molding principle of the above process is to plasticize two different plastics in two barrels, and then inject them into the mold cavity to form plastic parts with two colors (or two materials) on the surface. Anti-recirculation separator It is a typical two-color injection molded part, but the soft glue and hard glue of the two-color injection molded part are prone to poor lapping and cracking

Abstract

The invention relates to the technical field of two-color injection molding for automobiles, in particular to a soft and hard rubber lap structure for an automobile anti-recirculation partition, comprising: hard rubber laps that are respectively fixed and installed at the joints of hard rubber and soft rubber and overlapped with each other The joint part and the soft rubber lap part; the hard rubber lap part is provided with a first boss and a first accommodation groove, and the soft rubber lap part is provided with a second boss accommodated in the first accommodation groove , and a second receiving groove for receiving the first boss. In the car anti-recirculation partition soft and hard rubber lap structure of the present invention, the hard rubber lap part and the soft rubber lap part are all provided with receiving grooves and bosses that cooperate with each other, the lap joint effect is good, and it is not easy to break; In use, the bonding strength is strong, the use function and service life of the overlapping structure are enhanced, the mold structure is simplified, and the production cost is saved.

Description

technical field [0001] The invention relates to the technical field of two-color injection molding for automobiles, in particular to a soft and hard rubber overlapping structure for an automobile anti-recirculation partition. Background technique [0002] Two-color injection molding (also known as double-material injection molding) is a special plastic injection molding method developed in recent years to adapt to this trend. It can form two different colors or different plastics (such as a hard plastic and a soft plastic) ) is actually an "insert molding" process of in-mold assembly or in-mold welding. [0003] The molding principle of the above process is to plasticize two different plastics in two barrels, and then inject them into the mold cavity to form plastic parts with two colors (or two materials) on the surface. Anti-recirculation separator It is a typical two-color injection molded part, but the soft glue and hard glue of the two-color injection molded part are p...
