Description
Technical field
This utility model relates to the double-colored injection molding technology field of automobile, particularly to a kind of air conditioning for automobiles box assembly air door double-shot moulding structure.
Background technology
Air conditioning for automobiles can not only improve driver comfort, reduces driving fatigue degree, improve vehicle safety, and is improve one of vehicular grade, the important means improving the market competitiveness.And air door is the executor of air-conditioning box pattern, the performance of air-conditioning is played pivotal role.The air door of a basic air conditioning for automobiles specifically includes that internal-external cycle throttle, defroster door, blows face air door, blows foot air door and blender door.Tradition air door is by common injection mo(u)lding, and PP generally selected by material.Sealing between air door and housing is that this mode had both added material cost, also consumed substantial amounts of manpower, and therefore, the air door of common injection mo(u)lding is replaced by double-colored air door gradually by sticking the realization of half-open half-closed sponge in air door border.
Double-colored air door is when molding, the sealing structure being made up of flexible glue is formed at the edge of air door, its molding mode generally has two kinds: a kind of is that two, air door ebonite is overlapped different die for molding respectively with flexible glue part, first in one set of die by ebonite part injection out after, again ebonite is partially installed on the mould of flexible glue, carrying out second time injection moulding makes flexible glue be coated on ebonite, generally we term it secondary injection molding.Another kind is in same die for molding by air door ebonite part and flexible glue part, and first by after ebonite part molding, again through rotating die cavity molding flexible glue on ebonite, generally we claim this injection molding manner to be double-shot moulding.
Although adopting the quadric injection mould energy double-colored air door of molding, and forming die structure is simple, but it has some deficiency following compared to double-shot moulding: 1) soft, ebonite part respectively molding in one set of die, it is necessary to number of molds is two times of double-shot moulding, and die cost is higher；2) after ebonite molding, it is necessary to being removed from the molds by ebonite and place in flexible glue mould, complex procedures, molding cycle is longer；3) ebonite part is in the process taking out cooling, it may occur that contraction, deformation etc., after being placed again into flexible glue mould, it is difficult to ensure that the Forming Quality of flexible glue, causes that product burr is bigger；4) due in quadric injection mould process air door structure cool twice, cause that air door bulk deformation is bigger；5) air door is when putting into flexible glue mould, it is easy to scratch axle of the air door, affects air door Forming Quality.Therefore, generally adopt two-shot molding process molding at present, if but adopt original quadric injection mould air door structure, mould can be very complicated, brings very big difficulty to the design of mould, it is therefore desirable to air door structure is redesigned.
Utility model content
The purpose of this utility model is in that to provide one to be applicable to double-shot moulding, and required forming die structure is simple, and after molding, flexible glue part and ebonite part connect a kind of air conditioning for automobiles box assembly air door double-shot moulding structure reliably.
For solving above-mentioned technical problem, this utility model have employed a kind of air conditioning for automobiles box assembly air door double-shot moulding structure, including by the air door body of ebonite molding, and the sealing strip being coated on around air door body by flexible glue molding, described air door body perimeter is provided with ebonite connecting portion, sealing strip is correspondingly arranged on flexible glue connecting portion, ebonite connecting portion and flexible glue connecting portion and is disposed as step cantilever design, be connected between ebonite connecting portion and flexible glue connecting portion.
Further, described air door body being symmetrically arranged with multiple connecting hole, described connecting hole is arranged in the cantilever design of ebonite connecting portion.
Further, described connecting hole is mounting hole.
Further, the cantilever design width of described ebonite connecting portion and flexible glue connecting portion is not less than 2.5mm, and thickness is the half of ebonite connecting portion thickness.
Air door body and sealing strip connecting portion are set to the cantilever design of separate unit stepwise by this utility model, and compared to original bilateral cladding mode, the structure of connecting portion is simpler, and the mould structure for air door molding is also simpler；And by arranging kidney-shaped connecting hole on the connecting portion of air door body, considerably increase the bonding strength between ebonite part and flexible glue part, make the connection between air door body and sealing strip relatively reliable.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
As illustrated in fig. 1 and 2, for a kind of air conditioning for automobiles box assembly air door double-shot moulding structure, including by the air door body 1 of ebonite molding, and it is coated on around air door body 1 by the sealing strip 2 of flexible glue molding, described air door body 1 periphery is provided with ebonite connecting portion 4, sealing strip 2 is correspondingly arranged on flexible glue connecting portion 5, ebonite connecting portion 4 and flexible glue connecting portion 5 and is disposed as step cantilever design 6, be connected between ebonite connecting portion 4 and flexible glue connecting portion 5.When molding, first inject ebonite compound molding air door body in a mold, after air door is originally body formed, again through conversion die cavity at air door body surrounding injection flexible glue sizing material profiled weatherstrip, now by compact siro spinning technology mutual between connecting portion and the connecting portion of sealing strip of air door body, complete the double-shot moulding of air conditioning for automobiles box assembly air door.
In order to make the connection between air door body and sealing strip more stable, as shown in Figures 3 and 4, this utility model 1 is provided with multiple connecting hole 3 on air door body, and described connecting hole 3 is arranged in the cantilever design 6 of ebonite connecting portion 4.After air door is originally body formed, when sealing strip type intracavitary administration flexible glue sizing material, flexible glue sizing material is injected in the connecting hole on air door body, so that being connected more tight between flexible glue with ebonite, adds the bonding strength between air door body and sealing strip.Connecting hole is designed to mounting hole structure, can be effectively improved the Forming Quality of connecting hole and the structure of mould.
In air conditioning for automobiles box assembly air door structure, for ensureing there are enough bonding strengths between air door body 1 and sealing strip 2, the cantilever design width L of its ebonite connecting portion 4 and flexible glue connecting portion 5 should be not less than 2.5mm, and thickness h is set to about the half of ebonite connecting portion thickness H；Specifically, the cantilever design width L of ebonite connecting portion and flexible glue connecting portion is 2.5mm, and cantilever design thickness h is the half of ebonite connecting portion thickness H.
Specification and drawings of the present utility model is considered as illustrative and not restrictive; on this utility model basis; those skilled in the art are according to disclosed technology contents; just some of them technical characteristic need not can be made some replacements and deformation by performing creative labour, all in protection domain of the present utility model.
