Description

Instrument panel framework mold opening foaming sealing structure

Technical Field

The utility model relates to an automobile instrument board field, concretely relates to instrument board skeleton die sinking foaming seal structure.

Background

At present, the soft instrument board is widely applied to a middle-high grade instrument board driving area and has the characteristics of improving the appearance and the using effect of the instrument board. The foaming process of the soft instrument panel is always the key point for manufacturing the instrument panel, and the current foaming process of the instrument panel comprises open mold pouring and closed mold pouring.

The open-mold casting is to use the foaming casting nozzle of the ABB manipulator to cast the foaming material on the inner side of the skin in the open state of the mold as shown in FIG. 4 and FIG. 5, then to place the frame and close the mold to make the foaming material cross-link with the frame and the skin for curing. The process has the characteristics of high tolerance and high design freedom, can realize the simultaneous pouring of two instrument panel foaming molds by using a manipulator, and has low manufacturing equipment investment. Meanwhile, the pouring route can be adjusted by the mechanical arm for foaming and pouring, and foaming raw materials can be reasonably distributed according to the structure of the die, so that air holes generated by uneven filling of the foaming materials in the framework in the foaming process are avoided.

However, this process has the following disadvantages:

1. the instrument panel skin and the framework are required to have good sealing performance, a large number of soft sealing strips are required to be used for auxiliary sealing, the consistency of manually pasting the sealing strips by an operator cannot be guaranteed, so that the soft sealing strips cannot well seal foaming materials, and foaming leakage is easy to occur in the instrument panel foaming process;

2. because the soft sealing strips of the instrument panel framework and the surface are used in large quantities, the manual pasting time of operators is long, and the production efficiency is low.

Disclosure of Invention

The utility model aims at being not enough to above-mentioned technique, provide an instrument board skeleton die sinking foaming seal structure, improved the foaming sealing performance, reduced the use of soft sealing strip, the material rate of utilization is high, and production efficiency is high.

In order to realize the above-mentioned purpose, the utility model discloses an instrument board skeleton die sinking foaming seal structure, including installing the instrument board skeleton on last mould and the epidermis of flatly laying on the lower mould, all be equipped with the sealed muscle of skeleton on the skeleton brim of a hat of instrument board skeleton, the central zone of instrument board skeleton also is equipped with the sealed muscle of skeleton, the sealed muscle of skeleton with instrument board skeleton integrated into one piece that moulds plastics, when going up mould and lower mould compound die, the instrument board skeleton with pass through between the epidermis the sealed muscle of skeleton forms confined space.

Preferably, when the upper die and the lower die are closed, the interference amount between the framework sealing rib and the surface skin is 0.4-0.6 mm.

Preferably, the height of the framework sealing rib is 2-3 mm, and the width of the framework sealing rib is 2-3 mm.

Preferably, the crossing department of instrument board skeleton central zone skeleton sealing muscle forms contained angle a, contained angle a's big or small scope is 120 ~ 150, makes form the hypotenuse transition between the skeleton sealing muscle, can avoid the skeleton sealing muscle with the epidermis leads to pricking because of the interference volume is great the epidermis, also can guarantee simultaneously the skeleton sealing muscle with the interference utility of epidermis.

Compared with the prior art, the utility model, have following advantage:

1. a sealed space is formed between the instrument panel framework and the surface skin through the framework sealing ribs, so that foaming materials are prevented from overflowing from a filling area of the instrument panel framework and the surface skin, and surface depression and damage of the instrument panel caused by the overflow of the foaming materials are reduced;

2. the bevel edge transition is formed between the framework sealing ribs in the central area, so that the skin can be prevented from being punctured due to large interference between the framework sealing ribs and the skin, and the interference effect of the framework sealing ribs and the skin can be ensured;

3. the framework sealing rib and the instrument panel framework are molded integrally by injection, so that the production is simple, the structural size is stable, the manual error is reduced, and the defect of poor appearance of a foaming material is overcome;

4. the use of soft sealing strips and the working hours of heat sources are reduced, the material utilization rate is high, and the product percent of pass and the production efficiency are improved.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments.

As shown in fig. 1, the utility model discloses instrument board skeleton die sinking foaming seal structure, including installing instrument board skeleton 1 and the epidermis 2 of spreading on the lower mould on last mould, all be equipped with the sealed muscle of skeleton 4 on instrument board skeleton 1's the skeleton brim of a hat 3, instrument board skeleton 1's central zone 5 also is equipped with the sealed muscle of skeleton 4, and the sealed muscle of skeleton 4 and instrument board skeleton 1 integrated into one piece that moulds plastics, when going up mould and lower mould compound die, form the confined space through the sealed muscle of skeleton 4 between instrument board skeleton 1 and the epidermis 2.

In this embodiment, the height of the framework sealing rib 4 is 2.5mm, the width of the framework sealing rib 4 is 2.5mm, as shown in fig. 3, an included angle a is formed at the intersection of the framework sealing ribs 4 in the central area 5 of the instrument panel framework 1, and the included angle a is 120 °.
