Abstract
The present invention relates to a kind of vertical exhaustor casting device, including: the exhaustor casting pattern being made up of loam core and loam core shell, wherein: also include a clamping device, comprising: fixation clip；Some guide pillars, its one end is fixing with fixation clip surrounded surface to be connected；Movable pressing board, its surface offers the some guide holes matched with some guide pillars, and described movable pressing board can be accessed the guide pillar other end by guide hole set and can be slid axially along guide pillar；Wherein, described exhaustor casting pattern is installed between fixation clip and movable pressing board, and by movable pressing board toward fixation clip direction propelling clamping exhaustor casting pattern, and the blasthole of described exhaustor casting pattern, steam vent are arranged at the horizontal plane highest point of exhaustor casting pattern.The gas in exhaustor loam core can be discharged outside exhaustor casting device by this device, it is to avoid bubble, peeling, the phenomenon such as wrinkling occurs in exhaustor pipe shaft；And the phenomenon such as exhaust wall thickness ununiformity can be prevented even.
Description
Technical field
The present invention relates to a kind of exhaustor casting device, particularly to a kind of vertical exhaustor casting device.
Background technology
Exhaustor is the parts that automobile engine is crucial, and the qualified casting of exhaustor is low, below summary
Several big reasons:
1, greensand casting technique poor air permeability, easy butterfly-shaped shortbread.
2, when technological design, not having airtube, when pouring molten iron, high temperature causes core gas can not arrange, and produces
, there is substantial amounts of bubble in the place of product boss, causes the phenomenon such as product peeling, wrinkling, fleshiness.
3, the design of main core mold is unreasonable, and the loam core defect of injection is many, causes loam core gas forming amount big, intensity
Not, can rupture, yield rate is difficult to improve.
4, the gravity skew taking old-fashioned horizontal mo(u)ld core to be subject to due to the characteristic of exhaustor acts on, quilt
The moment that molten iron encases has been made discontinuity loam core, loam core produce by the effect of gravity and molten iron buoyancy
It is even that skew result in exhaust wall thickness ununiformity.
Summary of the invention
In order to overcome the deficiency in background technology, a kind of vertical exhaustor casting device, this device are invented
Can the gas in exhaustor loam core be discharged outside exhaustor casting device, it is to avoid exhaustor pipe shaft bubble occurs, rises
Skin, the phenomenon such as wrinkling；And the phenomenon such as exhaust wall thickness ununiformity can be prevented even.
For solving above-mentioned technical problem, the technical scheme is that
A kind of vertical exhaustor casting device, including: the exhaustor casting being made up of loam core and loam core shell
Model, wherein:
Also include a clamping device, comprising:
Fixation clip；
Some guide pillars, its one end is fixing with fixation clip surrounded surface to be connected；
Movable pressing board, its surface offers the some guide holes matched with some guide pillars, described movable pressing board
The guide pillar other end can be accessed by guide hole set and can slide axially along guide pillar；
Wherein, described exhaustor casting pattern is installed between fixation clip and movable pressing board, and by living
Dynamic pressure plate advances clamping exhaustor casting pattern, and described exhaustor casting pattern toward fixation clip direction
Blasthole, steam vent be arranged at the horizontal plane highest point of exhaustor casting pattern.
Preferably, described loam core shell is divided into upper shell and lower house, and upper shell and lower house pass through
Resin bonds.
It is compared with the prior art, the invention have the characteristics that and advantage:
1, the present invention takes vertical pouring to carry out into water from the peak of exhaustor casting pattern, when water falls into
Automatically drain the air inside the spontaneous gas in loam core and product.Upwards cast buoyancy and downward loam core from
On the same line, both stress can carry out the counteracting of maximum to gravity, substantially reduces the stress in loam core,
Make the uniform wall thickness of exhaustor when cast.The implementation of this new technology improves me and takes charge of the casting of exhaustor
Efficiency and yield rate.
2, the further advantage of the present invention is that vertical casting has only to fixation clip clamping, it is not necessary to bury sand, energy
Reduce the dust owing to kicking up the when that dress burying case.Substantially improve the casting bad border of employee, Er Qieli
Formula casting can also reduce the use in space, can accommodate the vertical row of twice at same horizontal casting space
Trachea casting device.
3, the further advantage of the present invention is for being by resin-bonding due to loam core shell after cast, then through too high
Loam core shell is burnt defeated and dispersed by Wen Houhui, and exhaustor finished product can drop automatically, decreases traditional founding of going and rises
The technique of exhaustor finished product.
Accompanying drawing explanation
Fig. 1 is the present invention vertical exhaustor casting device top view；
Fig. 2 is the present invention vertical exhaustor casting device right view；
Wherein: 1, fixation clip；2, movable pressing board；3, guide pillar；4, steam vent；5, nut；6、
Blasthole；7, upper shell；8, lower house；9, exhaustor casting pattern；10, guide hole.
Detailed description of the invention
Referring to the drawings and combine detailed description of the invention to further describe the present invention, to make this area skill
Art personnel can implement according to this with reference to description word, and scope is not limited to the present invention's
Detailed description of the invention.
As shown in Figure 1-2, a kind of vertical exhaustor casting device, including: by loam core and loam core shell group
The exhaustor casting pattern 9 of one-tenth, steam vent 4, blasthole 6, clamping device；Loam core shell is divided into upper casing
Body 7 and lower house 8, core device in the loam core case body that upper shell 7 and lower house 8 form, and
Upper shell 7 and lower house 8 are bonded by resin, by resin-bonding after high temperature when bonding
Can burn defeated and dispersed by loam core shell, exhaustor finished product can drop automatically, decreases traditional founding of going and plays aerofluxus
The technique of pipe finished product.
Clamping device includes: fixation clip 1, movable pressing board 2,5, four guide pillars 3 of nut, fixing pressure
The rectangular shape of plate 1 and in vertical configuration, four guide pillar 3 surfaces be furnished with screw thread and one end respectively with fixing pressure
The fixing connection of plate 1 surface surrounding and four guide pillars 3 are vertical with fixation clip 1 surface, movable pressing board 2
Rectangular shape and surface have four guide holes 10 matched with four guide pillar 3 other ends, movable pressing board 2
Access four guide pillar 3 other ends by four guide hole 10 sets, and movable pressing board 2 guide hole 10 can coordinate
Guide pillar 3 slides axially along guide pillar 3；By exhaustor casting pattern 9 in vertical be positioned over fixation clip 1 and
Between movable pressing board 2, and blasthole 6 and the steam vent 4 of exhaustor casting pattern 9 are located at exhaustor
The horizontal plane highest point of casting pattern 9, cast buoyancy upwards and downward loam core from gravity with the most always
On line, both stress can carry out the counteracting of maximum, substantially reduces the stress in loam core so that during cast
Wait the uniform wall thickness of exhaustor.Then it is screwed into four guide pillar 3 other ends by movable pressing board 2 by nut 5
Advance toward fixation clip 1 and exhaustor casting pattern 9 is clamped.
During work, blasthole carry out pouring molten iron, carry out into water from the peak of exhaustor casting pattern,
Automatically draining when water falls into the air inside the spontaneous gas in loam core and exhaustor product, air passes through exhaustor
It is discharged to outside.Upwards cast buoyancy and downward loam core from gravity on the same line, both stress
The counteracting of maximum can be carried out, substantially reduce the stress in loam core so that when cast, the wall thickness of exhaustor is equal
Even.
