Description
Technical field
The invention belongs to casting and molding equipment technical field, and in particular to a kind of self-hardening sand mixing device.
Background technology
Foregoing self-hardening sand mixing device is referred to as puddle mixer, for using as the liquid resin of binding agent and be used as reaction
The LCM of accelerator as the sand material of aggregate with stirring as molding sand, and molding sand is introduced directly into sandbox shaping box enters
Row molding and core making, this is widely used in the manufacturing process of cast such as glass mold.
The technical information on self-hardening sand mixing device can be seen in disclosed Chinese patent literature, it is typical such as document
A) " sand mulling auger used for resin self-hardening sand equipment " that .CN201530049U recommends, the positive effect of the patent is；Pass through solidification
Agent inlet sets curing agent nozzle and sets resin ejection nozzle to be connect to increase with sand material in screw feeder at resin inlet
Contacting surface（Contact range）, can both promote mulling even results, the mulling time can be shortened again and curing agent and tree can be moderately saved
Fat, for details, reference can be made to the 0005th section and 0014 to 0016 section of the patent specification.Document B) .CN103722123A offers
" a kind of boiling device for self-hardening sand puddle mixer ", the achievement of the patent application scheme is；By in one-level agitating device
One boiling case is set between two grades of agitating devices, is first transferred to when the dry sand as foregoing aggregate is to two grades of agitating device unloadings
Seethe with excitement in case, the blowing device on boiling case makes sand material（That is dry sand）Seethed with excitement in boiling sand, the ash content in dry sand rises outstanding
It is floating, ash content is extracted out by cyclone separator, improves dry sand quality, for details, reference can be made to the patent application the 0007th section of specification,
0012 section and 0019 section.
Relative to same batch products such as pattern, prior art generally uses the molding sand of same intensity, i.e., by self-hardening sand mulling
The intensity of molding sand that is that device is mixed out and introducing in sandbox or flask is identical from inside to outside, and for a long time all the time by
Deferred to as industry religious discipline, have no the relevant report queried.But in the applicant's production practices for many years and a large amount of
Engineer testing in find：During keeping that die cavity is indeformable, standing one's ground, required sand bond is die cavity from inside to outside
Different, i.e., internal intensity is big, and external intensity is small.So as to show in prior art to use same intensity using single intensity
There is very big irrationality or blindness in Foundry quartz sand mode, the result is that causing the waste of curing agent and resin.This
Outside, due to curing agent and resin price for sand material it is more expensive, thus cause moulding cost increase；And due to
Curing agent and resin demand are bigger, and the gas forming amount of molding sand is also bigger, thus the assorted probability for producing stomata of casting is higher, and to molding sand
Reuse regeneration difficulty it is bigger and influence of to environment is also bigger.
