Existing foaming mould, the die joint 10 of its mould is distributed with material in air discharge duct 101 (such as Fig. 1), mould and sent out
Bubble pushes out product finally by the air discharge duct 101 of die joint 10, waste material is thus produced outside die joint, air gun will can not be bonded at
The small ball of die joint exterior lateral area is blown away, if adding the operating time using brush cleaning, clearing up not in place easily cause
Air discharge duct is blocked, so as to influence the quality of foamed products.
Therefore, it is necessary to provide a kind of new technical scheme.
The content of the invention
In view of the shortcomings of the prior art, the present invention provides a kind of mould with secondary flanging die joint, and it not only facilitates
Operation, raising production efficiency, and improve the quality of foamed products.
In order to solve the above-mentioned technical problem, the invention provides a kind of mould with secondary flanging die joint, the mould
Tool includes upper die and lower die and the morphogenetic die joint of upper die and lower die matched moulds shape；
Air discharge duct is distributed with the die joint；
Discharge space is provided with the outside of the die joint, the discharge space stretches out from the outward flange of die joint,
The discharge spatial loop around the parting EDS maps,
The discharge space is secondary flanging die joint.
Further, the width in the discharge space is 8-12mm, and the height in the discharge space is 0.8-1.2mm.
Further, the width in the discharge space is 10mm, and the height in the discharge space is 1mm.
Further, the angle of the discharge space and die joint is 15-30 °.
Further, the air discharge duct is multiple, and multiple air discharge ducts are uniformly distributed on the die joint.
Further, the air discharge duct is in circular arc.
Further, the radius of the air discharge duct is 0.3-0.5mm.
Further, the air discharge duct is located at the upper mould of the die joint.
Further, the air discharge duct is located at the lower mould of the die joint.
A kind of mould with secondary flanging die joint of the present invention, has the advantages that：
The mould with secondary flanging die joint of the present invention, it passes through a circle increase 10mm on the outside of mold parting surface
Wide, the secondary flanging die joint in 1mm gaps, the waste material run out finally by inner side die joint air discharge duct that foams is being eventually passed through
Become 1mm thick flat slitter edges during twice parting face, the slitter edge is opened when mould and gone all without secondary flanging die joint is run out of
It is convenient to operate, improve production efficiency, improve foaming except direct air gun can just blow the slitter edge of secondary flanging open after foamed products
The quality of product.
Brief description of the drawings
