Description

Multi-colored product instantaneous cold/hot shaped method and former

Technical field

The present invention relates to moulding process and the apparatus field of multi-colored materials, be specifically related to the instantaneous cold/hot shaped side of multi-colored product Method and former.

Background technology

Current EVA and elastomeric material are widely used in every profession and trade field, particularly shoe-making industry because of the superiority of its material；This A little materials the most all use hot-die sulfidization molding system, and its mould temperature will control to note in stationary temperature situation just because of this Inject die cavity hot-forming or direct at die cavity hot-forming output goods.

It is known that EVA and elastomeric material are not moulded reaching its melting temperature in the case of before curing temperature in screw rod Progressive die chamber, sulfidization molding in die cavity can be molded after change；But it can become pureed by raw material in the range of injection temperature, so that passing Unite multi-color injection molded in the case of, be molded the raw material to last time injection next time and carry out impact extrusion and cause the raw material of twice injection to be gone here and there mutually, Cause colour contamination situation, so traditional multi-color injection molded technique can not realize the multicolour forming of EVA and elastomeric material.

And both materials hot-press vulcanization formative stage must to die cavity in gas extraction totally reach vacuum state, Goods are just unlikely to defects such as burning occur.

Realize EVA at present and elastomeric material polychrome produce and mainly takes following several ways to complete:

Under hot-die state, multiple gun completes monochromatic injection, more multiple monochrome is closed into the work of polychrome by mould structure Process, flow process is: hot-die-monochrome multimode cavity is molded-opens die cavity-extraction central dividing plate-Guan Bi polychrome die cavity-die cavity and takes out very Sky-sulfidization molding.After multimode cavity monochrome has been injected, after being closed by mould after extraction mould central dividing plate, evacuation carries out heat again Pressure sulfidization molding；But just injection complete rear raw material its pureed at a temperature of die cavity because being previously mentioned is even more serious, at die cavity two After secondary Guan Bi, the raw material of epicoele is easy to the raw material of impact extrusion cavity of resorption, causes polychrome unclear every color, and die joint colour contamination phenomenon is serious, Defect rate is high, is necessary for taking to retouch the production having painted multicolored products；The method technological process length, staffing are many, yield Low, equipment investment is big, defect ware is many, paint and poisonous, feature of environmental protection extreme difference simultaneously；The part with complicated structure cannot realize producing especially.

First chill product blank, then blank is inserted hot-die system carry out sulfidization molding and complete the process of polychrome, Flow process is: chill injection polychrome blank-taking-up blank-insert hot-die die cavity-closed mould cavity-evacuation-sulfidization molding or chill Monochromatic blank-taking-up blank-combination chill the blank of injection is polychrome-insert hot-die die cavity-closed mould cavity-evacuation-be sulfided into Type or chill injection polychrome blank-taking-ups blank-insert hot-die die cavity-repeatedly open and close die cavity-sulfidization molding or chill injection are singly Color blank-taking-up blank-combination chill blank is polychrome-insert hot-die die cavity-repeatedly open and close die cavity-sulfidization molding.The method Use injection machine that melted EVA and elastomeric material inject in the case of mould cools down the die cavity of cooling, can directly make many Color blank or be combined into polychrome blank after making multiple monochromatic blank；Again the polychrome blank combined is embedded in pressing machine After die material die cavity, Guan Bi mould evacuation or repeatedly keying mould realize sulfidization molding technique while carrying out aerofluxus；The party Method is primarily present following defect: the chill of (1) polychrome mould and hot-die cavity volume require very accurate, and difficulty of processing is very big； (2) blank is transferred to during hot-die inserts from chill, and after running into the mould of high temperature, the shades of colour of blank melts rapidly, phase Press from both sides colored situation mutually easily to be formed；(3) after blank is inserted, during pressing under mould Guan Bi hot-die epicoele easily extruding with The blank pigment of epicoele contact, causes its color to be gone here and there mutually, uses repeatedly keying mould to carry out aerofluxus and is more readily formed colour contamination；(4) mould Easy trapped air in tool, easily there is the situation of burning in multi-colored product finished product；(5) defect ware that process produces also needs by retouching Paint or the way sprayed paint solve colour contamination problem.

In sum: the moulding process of polychrome EVA and elastomeric material all exists a large amount of problem at present, equipment investment is big, work Process flow length, employee are equipped with many defects such as many, defect ware is many, the feature of environmental protection is poor, yield poorly.

In consideration of it, the problems referred to above are furtherd investigate by inventor, this case is then had to produce.
