Abstract
The invention discloses a horizontal parting fine oil duct core manufacturing device. Adjacent sand core sets and opposite sand core sets of a lower die block are arranged in a 180-degree turnover mode. Sand cores in each sand core set are arranged uniformly. Each sand core set is independently sealed. Sand jet nozzles and lower ejector rods are arranged in a staggered mode. An automatic core finishing mechanism under the sand cores is provided with parting face core finishing pieces and following core receiving columns. Burrs on the parting faces on the two sides of each sand core are scraped by the corresponding parting face core finishing piece when the sand core falls to the automatic core finishing mechanism. Each following core receiving column and the corresponding lower ejector rod are coaxially arranged. Each following core receiving column is matched with the sand core surface at the corresponding lower ejector rod. Ejector rod core burrs at the bottom face of each sand core are squeezed and fractured by the corresponding following core receiving column when the sand core falls. By adoption of the horizontal parting fine oil duct core manufacturing device, sand in a sand jet frame can flow uniformly, the phenomenon that the sand at a flow dead angle is lightly solidified and blocks the sand jet nozzles is avoided, sand core molding is compact and reliable, and the production rate is high; and by adoption of the automatic deburring core finishing mechanism, the burrs can be automatically removed, the phenomena of burr omission and sand core fracturing are avoided, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of core making machine, and in particular to a kind of thin oil duct core core making device of horizontal parting.
Background technology
Automobile engine cylinder-body is typical complex thin-wall ironcasting.For easy fracture and the loam core of distressed structure, for example
, at present using during the production of vertical-parting core making machine, easily there are a lot of problems in the oil duct core of SGMW B15D cylinder body：
1st, coremaking：For elongate curved, the larger core of changes of section, easy molding is bad to cause fracture, core quality
Unstable, most of using the hot core technique of precoated sand, the production cycle is longer, and cost is very high；And the hot core feature of itself, casting
Part corresponds to upper position and can produce slag blister, and spilehole brings difficulty to casting technique.
2nd, core finishing：Can there is die joint burr/push rod core burr in core, as vertical-parting core making machine can not be adopted after making
With automatic coring/core finishing, we can only carry out artificial coring/core finishing, and high labor intensive, has local and integral sand core burr leaks
Repair phenomenon；Also there is the physical phenomenon of Warm status deformation in hot core technique, we also need to take preventing hot deformation measure.
These intrinsic problems above-mentioned have a strong impact on our production capacity and technology stability.
Accordingly, it would be desirable to a kind of new technical scheme is to solve above-mentioned technical problem.
Content of the invention
For solving the deficiencies in the prior art, it is an object of the invention to proposing a kind of rational in infrastructure, reliable level of molding
The thin oil duct core core making device of typing so that core steady quality, production cost reduces.
In order to realize above-mentioned target, the present invention is adopted the following technical scheme that：A kind of thin oil duct core coremaking dress of horizontal parting
Put, the core making device includes core box body, sand shooting mechanism, post rod mechanism and automatic core finishing mechanism, and the core box body is by upper core
Box and lower core box are constituted, and lower core box includes low mold frame and the lower module in low mold frame, form one between upper core box and lower core box
Horizontally disposed core box chamber, is placed in parallel multiple core groups in the horizontal direction of the lower module in the core box intracavity portion, adjacent
Between core group and relative core group between 180 ° of upset arrangements of horizontal direction, core arrangement core group inside is unanimously；Per
The single group sealing of group core；In vertical direction, the sand shooting mouth of the sand shooting mechanism is arranged towards the top of core, the post rod mechanism
Lower push rod arrange towards the bottom of core, the sand shooting mouth mutually staggered with the lower push rod；The core finishing mechanism is arranged on
The lower section of core, the core finishing mechanism includes the cavity for being formed by lower module, and the cavity top tightens up to form oral area,
The cavity mouth rim is provided with die joint core finishing piece, and cavity inside is provided with and connects stem stem with type, the die joint core finishing piece
In the horizontal-extending encirclement core two sides of the oral area, when falling cavity under core, die joint burr in both sides is repaiied by the die joint
Chip strikes off；Described connect stem stem with type and be coaxially disposed with lower push rod, described connect core surface at stem stem and push rod with type and match,
When core falls, the push rod core burr of core bottom surface is connect stem stem squeeze crack by described with type.
Preferably, the sand shooting mouth is not with the lower push rod in the horizontal and vertical directions all on a plane.Sand shooting mouth
Lower push rod must not be arranged in lower section, to prevent resin sand under high pressure conditions from not stopping to wash away after push rod, can accumulate resin interference on push rod
Core is contoured
Wherein, the core has a ultra-thin banding core region, has in the die cavity in the ultra-thin banding core region
Air discharge duct, with steam vent in module, the air discharge duct keeps air-flow insertion with steam vent, by the type in ultra-thin banding core region
Intracavity gas are derived.By drawing the die cavity gas in ultra-thin core region, excluded by steam vent, so that sand filling is tight
Real, solidification is reliable.
The thickness range of the air discharge duct is 0.1-0.3mm.More preferably, the thickness of the air discharge duct is 0.2mm.
Preferably, the die joint core finishing piece is with the gap of core die joint less than core die joint burr horizontal direction
Length.Gap is little so that the core with die joint burr relies on self gravitation and die joint core finishing piece in dropping process
Effect, can effectively strike off core die joint burr.
Preferably, described stem stem radius is connect more than push rod radius 2-4mm with type.More preferably, described with type, stem stem radius is connect
More than push rod radius 3mm.Stem stem radius is connect more than push rod radius with type, the top of a week at the push rod position of core bottom surface can be contained
Bar burr, effectively removes large-area push rod burr.
Preferably, after falling cavity under the core, the die joint core finishing piece is higher than core die joint 1-4mm.
More preferably, the die joint core finishing piece is higher than core die joint 2-3mm.Now the typing core finishing piece of both sides can rise
To protective effect, prevent lower section push rod burr from connecing core play when stem stem is extruded with type, so as to produce fracture.
The invention has benefit that：The thin oil duct core core making device of the present invention adopts horizontal parting, single core group
Sealing, prevents gas blowby；Core group layout adopts 180 ° of reverse arrangement, makes to penetrate the flowing of sand inframe sand uniformly, prevents flow blind angle
Place's sand blocks sand shooting mouth after slightly solidifying；The ultra-thin banding core region in core local increases exhaust mode profit using air flue drain
In core molding, for the big core of tiny, bending, changes of section, molding consolidation reliability, core yield rate height.While adopting
The core finishing mechanism of automatically removing burr, it is ensured that all lower push rod burrs and die joint burr are automatically removed, and protect core repairing
Do not rupture in core overall process, so as to ensure to obtain qualified core, before elimination, artificial removal's burr is unreliable and beat is slow
Problem.
