Description
Technical field
The present invention relates to injection mold, be specifically related to a kind of double-color mold.
Background technology
Plastic products great majority by injection mold shaping, the plasthetics of required profile is molded efficiently by injection mould prodigiosin, thus accelerating the developing steps of injection mold, double color injection refers to the process two kinds of different colours or different types of plastics being made different color or the different finished product of appearance soft durometer by injection molding processes.
According to prior art, for existing shaping there is the plasthetics of two kinds of colors or two or more color time, especially quadric injection mould product is had for product two die cavity and core, there is plastic, rubber-coating on product two sides, mould needs to change slide block and front mould, need rotary shaft injection machine just can complete injection moulding, but the Mould Machining required precision of rotary shaft type two-color die is high, need to eject die after first time injection moulding, then die rotates 180 °, then die retracts, last mold-closing injection is shaping, injection moulding process needs to repeat to eject die, and eject die and utilize many thimbles to realize, die eject rotation 180 ° again matched moulds just need the dimensional accuracy of thimble very high, namely require that Mould Machining required precision is high, cost increases greatly.
Summary of the invention
Technical problem to be solved by this invention is: the defect overcoming above prior art, provides a kind of Mould Machining required precision the low double-color mold that cost is greatly reduced.
The technical solution used in the present invention is: a kind of double-color mold, it comprises cope match-plate pattern, lower bolster, slide block and die holder, described lower bolster is fixed on die holder, described cope match-plate pattern is positioned at the top of lower bolster, front mould push pedal is provided with between described cope match-plate pattern and lower bolster, described slide block is located in front mould push pedal, described front mould push pedal and cope match-plate pattern when the demoulding together and lower bolster is thrown off and front mould push pedal is separated with between cope match-plate pattern, the lower surface of described die holder is fixed with rotating disk, described slide block is provided with guide pillar hole, described cope match-plate pattern is provided with the guide pillar be slidably matched with slanting guide pillar hole.
After adopting above structure, the present invention compared with prior art has the following advantages: double-color mold needs twice injection moulding, especially outer surface encapsulate, generally all rotary shaft type two-color die can be selected, rotary shaft type two-color die needs to repeat to eject die in injection moulding process to be repeated to rotate, eject die and need many thimbles, the dimension precision requirement of thimble is very high, not so die is difficult to reset after rotating, make rotating disc type into, front mould push pedal is increased between cope match-plate pattern and lower bolster, slide block is located in front mould push pedal, during first time injection moulding, first to side injection moulding ebonite, after injection moulding completes, cope match-plate pattern is separated from lower bolster together with front mould push pedal, product is stayed on lower bolster, then rotating disk is utilized to rotate 180 ° to die holder, die holder is together with the lower bolster, be equivalent to lower bolster and rotate 180 °, then front mould push pedal and slide block is changed, matched moulds carries out second time injection moulding, to this side injection moulding flexible glue, to opposite side injection moulding ebonite, these two injection mouldings are carried out simultaneously, complete the injection moulding of double color mould, the product be positioned on lower bolster is finally ejected after die sinking, following matched moulds-the product of ebonite side, side flexible glue injection moulding-die sinking injection formed ejects lower bolster and rotates 180 °-matched moulds, circulate so always, principle is product injection moulding is the last injection moulding of the first injection moulding flexible glue of ebonite, overall owing to only needing to rotate die holder, therefore low to the requirement on machining accuracy of thimble, mould requires low, cost greatly reduces, cope match-plate pattern is separated with front mould push pedal is convenient to the demoulding.
As preferably, described front mould push pedal refers to that cope match-plate pattern bottom surface is fixed with pull bar with being separated between cope match-plate pattern, described pull bar away from one end of cope match-plate pattern through the lower surface of front mould push pedal, described front mould push pedal and pull bar are slidably matched, described pull bar is provided with clamping mechanism away between one end of cope match-plate pattern and front mould push pedal, described cope match-plate pattern bottom surface is provided with guide rod, described guide rod is positioned at lower bolster through front mould push pedal, described guide rod is slidably fitted in lower bolster and front mould push pedal, utilize pull bar to realize cope match-plate pattern to be separated with front mould push pedal, after pull bar moves a period of time, projection is stuck in spacing hole, pull bar moves on continuing, projection hauls front mould push pedal and up moves, front mould push pedal is separated with lower bolster, guarantee is separated and cope match-plate pattern and front mould push pedal also connect together.
As preferably, to be pull bar be provided with projection away from one end of cope match-plate pattern to described clamping mechanism, described front mould push pedal is provided with spacing hole, the diameter of the nearly lower bolster one end of described spacing hole is more than or equal to protruding diameter, the diameter of the nearly cope match-plate pattern one end of described spacing hole is less than protruding diameter, described pull bar is slidably fitted in spacing hole, described projection is slidably fitted in lower bolster, utilize the distance between the bottom of pull bar with spacing hole upper end that cope match-plate pattern is separated with front mould push pedal, pull bar is stuck in spacing hole upper end and cope match-plate pattern and front mould push pedal is connected together simultaneously, front mould push pedal can not be dropped, structure is simple.
