Abstract
A double-material injection molding foaming light automobile instrument panel ornament is characterized in that the double-material injection molding foaming light automobile instrument panel ornament is composed of a surface leather face (1), a foaming layer (2) and an injection molding framework (3). The injection molding framework (3) is provided with two mold cavities, and the foaming layer (2) and the surface leather face (1) are arranged in the mold cavities in sequence. According to the double-material injection molding foaming light automobile instrument panel ornament, due to the structure, raw material consumption is low, waste is small, the weight is 20% lighter than that of a recyclable product, the product is good in weatherability, an adhesive property between two materials is good, the size of the product is easy to control, and conformity is good.
Description
Technical field
The present invention relates to a kind of automotive upholstery, especially about the soft decorative element gauge panel of a kind of automotive trim new construction.
Background technology
Be accompanied by the lifting of rapid development of automobile industry and consumption of resident level, soft automobile component more and more is subjected to customer's welcome.Known automotive upholstery is first injection mo(u)lding skeleton, flame treatment is done on the skeleton surface or spray glue is handled, slush moulding/plastic-blasting/plastics sucking moulding epidermis again, and then toward filling-foam material between skeleton and the epidermis, part parts even needs just can be finished the course of processing of parts through complicated pruning operation, promptly produce parts and need experience 3-4 operation, and each operation all to use different Fabricating machinerys and corresponding operating personal to go to finish.The traditional processing technology shortcoming is as follows: 1, equipment input, raw MAT'L use, energy resource consumption and labour demand are all high; 2, the disposable qualification rate of product is low, and production efficiency is extremely low, the waste of raw materials height; 3, foaming layer and skeleton bond properties are poor; 4 product returnabilities are poor.
Summary of the invention
At above deficiency, the object of the present invention is to provide a kind of later-model extra quality injection moulding micro-foaming light automobile instrument panel gadget, is the having in two die cavities of injection moulding skeleton, is disposed with foaming layer and epidermis side, to improve the intensity of product, reduce product rejection rate.
Technical scheme of the present invention realizes in the following manner: extra quality injection moulding micro-foaming light automobile instrument panel gadget, form by epidermis side, foaming layer and injection moulding skeleton, it is characterized in that: the injection moulding skeleton has two die cavities, and foaming layer and epidermis side set gradually therein.
Structure of the present invention drops into less relatively; Raw materials consumption is low, less wastage, and lighter by 20% than the returnability product weight is arranged, and adhesive property is good between product thermal life and the two kinds of material; Product size is easy to control, high conformity.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Known that by Fig. 1 extra quality injection moulding micro-foaming light automobile instrument panel gadget is made up of epidermis side 1, foaming layer 2 and injection moulding skeleton 3, injection moulding skeleton 3 has two die cavities, and foaming layer 2 and epidermis side 1 set gradually therein.
Its processing technology is: earlier at left side injection moulding skeleton 3, skeleton 3 thickness are 3mm, and opening mold does not take out the injection moulding skeleton then, directly close mould behind rotating core 180 degree; The right side is continued injection moulding and is expected firmly, the soft material TPE of injection moulding simultaneously, soft material thickness 2.5mm sends into nitrogen in the soft material of left side injection moulding, form epidermis side 1 after soft material injection moulding is finished, the die cavity of epidermis side 1 4mm that draws back, core keeps the home position motionless, can form a cavity like this in the mould of left side and allow soft material finish foaming layer 2 in mould, and opening mold took out the fabricated part in left side after foaming was finished, and then rotating core 180 degree back matched moulds, continuous like this cyclic process product.
Claims (1)
1. extra quality injection moulding micro-foaming light automobile instrument panel gadget, it is characterized in that: form by epidermis side (1), foaming layer (2) and injection moulding skeleton (3), injection moulding skeleton (3) has two die cavities, and foaming layer (2) and epidermis side (1) set gradually therein.
