The further preferred embodiment of the present invention: the material path is included in the linking of cope plate center and extends to four direction
Main stem and main stem end be connected and to the arterial highway of the multi-direction extension in periphery, the end of the arterial highway be provided with it is upper
The through-hole of type chamber conducting, the through-hole correspond to the part of upper impression molding base angle.
The further preferred embodiment of the present invention: the center of the end position face polygonal star of the main stem.
The further preferred embodiment of the present invention: five lower impressions are both provided in each region, five lower impressions are to form
The part of base angle is that bosom is regularly arranged into five-pointed star.
The further preferred embodiment of the present invention: the main stem end has been connected the arterial highway of five different directions, and one dry
Road corresponds to a upper impression, the part of the through-hole face upper impression molding base angle.
The further preferred embodiment of the present invention: the outer edge of the lower template is additionally provided with one and irises out air drain, described
Outgassing groove surrounds a closed figures, and outgassing groove is located at outside multiple lower impressions.
The further preferred embodiment of the present invention: the air discharge duct for connecting lower impressions connects outlet passageway or outgassing groove nearby.
The further preferred embodiment of the present invention: the outlet passageway adapts to lower impressions arrangement setting.
Compared with the prior art, the advantages of the present invention are as follows existing molding die is different from, the present invention will be on rubber parts
Under be divided into two parts, formed respectively by upper impression, lower impressions.Lower template is provided with criss-cross outlet passageway, out
Lower template is separated into four regions by gas channel.Outlet passageway is set to realize to the air discharge in lower impressions.Lower impressions connect
It is connected to air discharge duct, criss-cross outlet passageway is set, air discharge duct is enabled to connect outlet passageway nearby.It is multiple in region
Lower impressions surround polygonal star structure, and lower impressions form the part of base angle near the center of polygonal star, and lower impressions form outside
Part is located at the edge of polygonal star structure and is connected with air discharge duct.Lower impressions are planned in lower template, first will meet its exhaust
Demand, avoids rubber parts bulge, second will be more as far as possible setting lower impressions, improve the production efficiency of product, third is wanted to plan
Honest material road structure saves bottom material.Multiple lower impressions are surrounded into polygonal star structure, can perfectly reach above-mentioned requirements.This hair
The cavity design of the bright molding rubber parts of planning again, designs exhaust passage, improves the yield rate of rubber parts；Design the pan feeding of rubber
The generation of waste material is reduced in channel.
