Problems solved by technology

[0002] Two-color plastic parts for automobiles are a common technique in the automobile manufacturing industry, and the existing anti-recirculation partition is a standard two-material injection molding. This anti-recirculation partition acts as a seal to block the gas circulation in the engine compartment. While existing anti-recirculation partitions such as figure 1 and figure 2 As mentioned above, the overlapping method of soft rubber and hard rubber is butt forming, but the overlapping joint of such butt forming is easy to crack

Embodiment Construction

[0014] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] -Such as image 3 and Figure 4 As shown, the soft and hard rubber lap structure of the anti-recirculation partition of the present invention, the soft rubber A2 and the hard rubber B2 are each fixedly installed with a lap structure at the junction, and the thickness of the lap structure of the hard rubber B2 is W1 is 1 mm. The thickness W2 of the overlapping structure of the soft rubber A2 is 1mm. The overlapping amount L of the bonding structure of the soft rubber A2 and the hard rubber B2 is 5mm. In this way, the mold forming of the part itself is easy, the effect of the overlapping of soft and hard rubber is good, and it is difficult to break at the overlapping of soft and hard rubber. At the same time, this is more beneficial to the injection molding of parts and saves costs.

Abstract

The invention discloses a soft and hard rubber lap joint structure for a recycling-prevention partition board. Two lap joint structures are fixedly arranged at joints of soft rubber and hard rubber respectively, and are matched with each other in a lap joint manner. The soft and hard rubber lap joint structure for the recycling-prevention partition board provided by the invention has the advantages of easy mold forming, good lap joint effect of soft and hard rubber and the like, is high in bonding strength when in use, and is difficult to break at the lap joint position of the soft and hard rubber, the using function is strengthened, the service life is prolonged, the mold structure is simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to the automobile manufacturing industry, in particular to a soft and hard rubber overlapping structure for an anti-recirculation partition. Background technique [0002] Two-color plastic parts for automobiles are a common technique in the automobile manufacturing industry, and the existing anti-recirculation partition is a standard two-material injection molding. This anti-recirculation partition acts as a seal to block the gas circulation in the engine compartment. While existing anti-recirculation partitions such as figure 1 and figure 2 As mentioned above, the overlapping method of the soft rubber and the hard rubber is butt forming, but the overlapping of such butt forming is easy to crack. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a soft and hard rubber lap joint structure for anti-recirculation partitions that has good lap joint effect and is diff...
