Description
Technical field
The invention belongs to injection-moulding device field, more particularly to a kind of mold for preventing runner from blocking and its working method.
Background technology
External injection molding machine industry starting is more early, advanced injection molding machine the relevant technologies has been grasped, in large size plastic jetting-moulding device, special injection molding
Machine and precise injection machine have first-strike advantage.But the injection molding machine industry of China passes through development for many years, in precise injection machine control
Also great breakthrough is achieved in the R and D of system processed, whether in management level, product variety, technical merit, production
Product class and application new and high technology etc., the gap all between diminution and developed country.
As Germany proposes that industrial 4.0 national strategies and China market are continuous for injection molding machine product performance requirement first
It improves, the domestic manufacturing technical merit of injection molding machine is just continuously improved in autonomous innovation.But the need increasingly too high in face of market
The domestic and international competition of the same trade of summation, enterprise wants to show one's talent, it is necessary to constantly lower raw tea cost, improve production efficiency.
Since injection molding machine is completed to be molded by plastic liquid, however the temperature of fluid understands rapid decrease in injection moulding process, therefore
Often will produce runner block the phenomenon that, especially in the longer mold of flow channel length, runner block the phenomenon that it is very serious,
So that entire product rejection, has greatly raised the production cost of moulding, has reduced production efficiency.Therefore, a energy
It is very necessary enough to solve the injection mold of runner blockage problem.
Present mold, the main problems are as follows：
1, present mold can not fundamentally solve the problems, such as that runner blocks mostly, can only again be dredged after runner blocking,
Moulding can be not only scrapped, production cost is improved, can also waste the production time, reduces production efficiency.
2, present mold cannot exclude air extra inside cavity mostly, cause waste product, bad product rate high.
Invention content
Goal of the invention：In order to overcome the above deficiency, the object of the present invention is to provide it is a kind of prevent runner block mold and
Its working method can provide enough heats for fluid so that fluid will not solidification in runner again, cause runner to block；
Meanwhile cavity being used to collect the air that can not be discharged in cavity, improve the quality of product.
Technical solution：To achieve the goals above, the present invention provides a kind of molds for preventing runner from blocking, including：On
