The invention discloses an adhesive force enhanced double injection molding plastic part structure in the field of plastic parts, which comprises a hard rubber layer and a soft rubber layer, the top of the hard rubber layer is provided with a connecting groove, the interior of the connecting groove is fixedly connected with a connecting skeleton, both sides of the connecting skeleton are provided with cavities, both sides of the top of the connecting skeleton are provided with rectangular grooves, and the rectangular grooves are fixedly connected with the soft rubber layer. The two sides of the hard rubber layer are fixedly connected with connecting supports, the tops of the connecting supports are fixedly connected with forked supports, the bottom of the soft rubber layer is fixedly connected with a protruding block, the top of the protruding block is fixedly connected with a square corner block, the top of the soft rubber layer is provided with a concave channel, the interior of the concave channel is connected with the connecting supports in a sleeved mode, and the top of the protruding block is fixedly connected with the cavity. The outer surfaces of the square corner blocks are fixedly connected with the rectangular grooves; according to the invention, the hard rubber layer and the soft rubber layer are combined more tightly by connecting the framework and increasing the contact area of the hard rubber layer and the soft rubber layer, and the soft rubber layer and the hard rubber layer cannot move back and forth to cause dislocation when being combined through the protective strip.

    本发明公开了塑胶件领域的一种增强附着力的双射模成型塑胶件结构,包括硬胶层与软胶层,硬胶层的顶部开设有连接凹槽,连接凹槽的内部固定连接有连接骨架,连接骨架的两侧均开设有空腔,连接骨架顶部的两侧开设有矩形凹槽,硬胶层的两侧均固定连接有连接支架,连接支架的顶部固定连接有分叉支架,软胶层的底部固定连接有凸块,凸块的顶部固定连接有方形角块,软胶层的顶部开设有凹陷通道,凹陷通道的内部与连接支架套接,凸块的顶部与空腔固定连接,方形角块的外表面与矩形凹槽固定连接;本发明中,通过连接骨架,增加硬胶层与软胶层得接触面积,使硬胶层与软胶层结合得更加紧密,通过防护条,使得软胶层与硬胶层结合时,不会前后移动导致错位。
