Reversing radar support assembling die

Abstract

The invention provides a reversing radar support assembling die which comprises an upper die and a lower die which correspond to each other up and down, and a guide column mounted between the upper die and the lower die, and a plurality of groups of upper die cavities are formed in the surface of the bottom of the upper die; multiple groups of lower die bulges are arranged on the top surface of the lower die; the upper mold cavity comprises a bracket positioning groove and a 3M glue positioning groove which are communicated up and down; the 3M glue positioning grooves and the support positioning grooves are distributed inside and outside at the same time. A supporting opening hole is inwards formed in the center of the protruding surface of the lower die, and opening grooves are further formed in the hole walls of the two sides of the supporting opening hole. The invention provides a novel assembling die which can press a plurality of reversing radar supports of various models at the same time, so that the processing efficiency is improved; 3M glue can be pre-pressed, so that the smoothness of the 3M glue is ensured, and wrinkles and bubbles are effectively avoided; 3M glue centering is effectively guaranteed, the consistency is improved, and the 3M glue is prevented from being attached obliquely and stretching out of the support; when the upper die and the lower die are pressed, the pressing force and the pressing time can be cured, and the pasting effect is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile parts processing, and in particular relates to a pre-assembly mold for a backing radar bracket. Background technique [0002] The reversing radar bracket is an important part of the car, which is used to fix the reversing radar and realize the parking assistance function. Contains the bracket body and 3M glue, 3M glue needs to be attached to the bracket body during assembly. Three problems are prone to occur during the assembly process: First, the 3M glue is soft, and it is easy to bend under force when pasting, resulting in wrinkling and air bubbles on the release paper, which reduces the sticking force. Second, the 3M glue is easy to stick to the wrong side, causing the 3M glue to stick out of the bracket, reducing the effective sticking area and reducing the sticking force. Third, the 3M glue is not fully stressed when it is pressed, resulting in partial areas not being fully pressed, and ...

Problems solved by technology

Three kinds of problems are prone to occur during the assembly process: First, the 3M glue is soft, and it is easy to bend under force when pasting, resulting in wrinkling and air bubbles on the release paper, which reduces the sticking force

Second, the 3M glue is easy to stick to the side, causing the 3M glue to stick out of the bracket, the effective sticking area is reduced, and the sticking force is reduced

Third, the 3M glue is not fully stressed when it is pressed, resulting in partial areas not being fully pressed, and the sticking force cannot reach the best effect

Fourth, the pressing force of 3M glue is insufficient and the pressing time is insufficient, resulting in the sticking force not reaching the best effect
