Abstract
The invention discloses an injected part coating technology of an automobile handrail. The injected part coating technology comprises the following steps: step one, performing injection molding on a handrail skeleton, namely performing the injection molding on a skeleton injection mold through a PP material, wherein the injection temperature is 170-200 DEG C, and the injection molding period is 50-70s; step two, performing the injection molding on a handrail skin, namely performing the injection on a skin injection mold through an EPDM material, wherein the injection temperature is 140-160 DEG C, and the injection molding period is 45-65s; and step three, assembling the handrail skeleton and the handrail skin, preheating the handrail skin with the temperature of 60 DEG C, and then stretching the handrail skin to cover the surface of the handrail skeleton. The automobile handrail disclosed by the invention is subjected to two-time molding, and easy to in assemble, a production process is improved, the number of operators is reduced, the production efficiency is improved, the production cost is lowered, and the abrasive resistance of the injected skin and the automobile handrail service life are better than those of a general soft skin.
Description
Technical field
The present invention relates to automotive upholstery production field, particularly relate to a kind of moulding cladding process of automobile armrest.
Background technology
Automobile armrest is the common components of automobile.General automobile armrest is combined by skeleton and epidermis, and traditional epidermis adopts plastic uptake PVC epidermis or follow-up foaming, to reach bating effect.But there is epidermis assembling trouble, anti-wear performance is poor, the problem that service life is short.
Summary of the invention
Goal of the invention: the invention solves the problems referred to above, provides a kind of moulding cladding process of automobile armrest.
Technical scheme: a kind of moulding cladding process of automobile armrest, comprises the following steps:
Step 1, the injection mo(u)lding of armrest skeleton, adopt PP material to carry out injection moulding to skeleton injection mold, injection temperature is 170 ~ 200 DEG C, and injection molding cycle is 50 ~ 70 seconds;
Step 2, the injection mo(u)lding of armrest epidermis, adopt EPDM material to carry out injection moulding to epidermis injection mold, injection temperature is 140 ~ 160 DEG C, and injection molding cycle is 45 ~ 65 seconds;
Step 3, armrest skeleton and armrest epidermis assemble shaping, and carry out preheating to armrest epidermis, preheat temperature is 60 DEG C, and then being stretched by armrest epidermis is coated on armrest skeleton surface.
As a preferred embodiment of the present invention, in step 2, injection pressure is 50 ~ 65kg/cm
2.
Beneficial effect: compared with prior art, its remarkable advantage is, present invention process is simple in the present invention, steady quality, product surface decorative pattern can be selected as required simultaneously, makes, evade the limitation that traditional handicraft can only select ready-made epidermis decorative pattern by the dermatoglyph of common Shooting Technique mould.Product post forming of the present invention, assembling is simple, improves production technology, reduces operating personnel, improves production efficiency, reduces production cost, and the wearability of the epidermis of injection moulding simultaneously and life of product are all higher than general soft epidermis.
Detailed description of the invention
Below in conjunction with detailed description of the invention, illustrate the present invention further.
Embodiment 1
The present invention discloses a kind of moulding cladding process of automobile armrest, comprises the following steps:
Step 1, the injection mo(u)lding of armrest skeleton, adopt PP material to carry out injection moulding to skeleton injection mold, injection temperature is 170 ~ 200 DEG C, and injection molding cycle is 50 ~ 70 seconds;
Step 2, the injection mo(u)lding of armrest epidermis, adopt EPDM material to carry out injection moulding to epidermis injection mold, injection temperature is 140 ~ 160 DEG C, and injection molding cycle is 45 ~ 65 seconds, and injection pressure is preferably 50 ~ 65kg/cm
2;
Step 3, armrest skeleton and armrest epidermis assemble shaping, and carry out preheating to armrest epidermis, preheat temperature is 60 DEG C, and then being stretched by armrest epidermis is coated on armrest skeleton surface.
The present invention directly adopts two injecting products assembled formations, utilizes the soft characteristic of EPDM, and simultaneously by the fixed installation structure of moulding indoor design back-off, connect and always lean on, anti-wear performance is good simultaneously, long service life.
To be apparent for those skilled in the art to the multiple amendment of embodiment, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Claims (2)
