Technical field
The present invention relates to the method for a kind of manufacturing direction dish cover, be specifically related to a kind of method manufacturing integrated direction indicators cover.
Background technology
Traditional direction indicators cover is divided into internal layer and skin, and wherein cladding material surrounds inner layer material, then utilizes sewing technology materials at two layers to be stitched into a complete direction indicators cover product.
But in the manufacturing process of traditional direction indicators cover, need to manufacture respectively internal layer and outer and need materials at two layers to be stitched together, thus technique is comparatively complicated.On the other hand, traditional direction indicators cover only focuses on the skid resistance between the inner surface of internal layer and steering wheel usually, and for the skid resistance of the outer outer surface with human contact, also needs the subsequent technique added to realize.
Summary of the invention
The object of the invention is to overcome above-mentioned technical problem, the manufacture method of the simple direction indicators cover of a kind of technique is provided.The direction indicators cover manufactured by method of the present invention is good antiskid effect, lightweight but also free from extraneous odour not only.
Method according to use elastomeric material manufacturing direction dish cover of the present invention can comprise the following steps:
Mould is prepared according to designing requirement;
Elastomeric material is mixed with additive, within described additive package accounts for 10% of gross weight containing AC blowing agent and described AC blowing agent.
When elastomeric material is elastomeric material, the step that elastomeric material mixes with additive is comprised further:
By banburying glue or open refining glue mode elastomeric material and described additive are stirred:
The composite material of elastomeric material and described additive is put into container and injected die cavity so that foaming by runner of heating, or solid-state material is put into die cavity then foaming according to standard weights.
When elastomeric material is plastic material, the step that elastomeric material mixes with additive is comprised further:
By homogenizer by plastic material and described additive Homogeneous phase mixing;
The composite material of elastomeric material and described additive is put into container and injected die cavity then foaming by runner of heating, or then physical blowing shapes.
When elastomeric material is polyurethane material, the step that elastomeric material mixes with additive is comprised further:
According to a certain percentage polyisocyanates material and combined polyether material are put into container, described ratio is 4: 6 to 6: 4;
Under the effect of pump, described composite material is injected die cavity;
When mould is through heating region, composite material is foaming in die cavity.
Compared with the conventional method of overlapping with manufacturing direction dish, owing to present invention employs once formed in mould mode manufacturing direction dish cover, so can greatly enhance productivity; In addition, employ blowing agent due in the process of overlapping at manufacturing direction dish, thus can reduce material proportion, save material and economize energy.
