Description
Technical field
The utility model relates to ironcasting sand casting fields, belong to a kind of placing sand in self-hardening sand casting control chill gap
Block.
Background technique
1, in foundry production, chill plays important influence to the quality of casting: being 1. difficult to feeding in riser
Position prevents shrinkage cavity and porosity.2. preventing wall thickness crossover sites and change dramatically position from cracking.3. it is used cooperatively with riser,
It can reinforce the consecutive solidification condition of casting.4. expanding riser feeding distance or range, riser number or volume are reduced.5. using chill
The cooling for accelerating individual thermal centers, make entire casting close to and meanwhile solidify.Not only casting deformation can be prevented or mitigated, but also work can be improved
Skill yield rate.
2, chill plays casting quality very important effect, thus the position of chill put it is also particularly significant.But
It is in actual production process, it must there are gaps between every block of chill.If the small―gap suture between chill is too small, the type in gap
Sand intensity difference, when casting, can be washed away by molten iron and cause sand hole；And chill gap is excessive will lead to technique thermal center, makes casting
Generate new casting flaw.Suitable chill gap should control between 10-15mm.
3, since in sand casting, the mostly operator that puts of chill puts by hand, so the stabilization in chill gap
It is larger to control difficulty, has severely impacted casting quality, there is an urgent need to a kind of reliable methods to be resolved.
Utility model content
The purpose of this utility model seeks to propose a kind of scheme and method for controlling chill gap, prevents chill gap mistake
It is big or too small, avoid the influence to casting quality.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of placing sand block in self-hardening sand casting control chill gap, including an attachment base, the attachment base internal environment
Array is provided with several sliding eyes, and the sliding eye is flat structure, be provided in the middle part of the attachment base with each sliding eye
Between the press hole that is connected to, the both ends in the press hole have been connected through a screw thread addendum cone block；It is slidably connected in the sliding eye
Placing sand block backing plate, one end of the placing sand block backing plate are provided with a top flat for contacting with addendum cone block, the placing sand block pad
The other end of plate is provided with width shim identical with attachment base thickness；The end of the addendum cone block is conical structure,
The transverse ends of the top flat are provided with the inclined surface tangent with the addendum cone block circular conical surface.
The width of the shim and top flat is greater than in the middle part of placing sand block backing plate as a further improvement of the utility model,
Width, the sliding eye inner wall are provided with slide protrusion corresponding with width in the middle part of placing sand block backing plate, slide protrusion and placing sand block
It is slidably connected between in the middle part of backing plate.
The separation on-chip array is stamped with several lug bosses as a further improvement of the utility model, lug boss with
Shim is structure as a whole, and the section of tabs is isosceles angle structure.
The placing sand block backing plate is formed using resin self-setting sand moulding as a further improvement of the utility model,.
The addendum cone block, which is adopted, as a further improvement of the utility model, is made of a steel, and the circular conical surface of end uses certainly
Animi resin sand molding forms.
The beneficial effects of the utility model are:
1, effective control has been obtained to chill gap, has improved the quality of casting.
2, when encountering the inclined-plane up extended or arc surface need to place chill, placing sand block also functions to linking chill and cold
The effect of ferropexy.
3, the utility model realizes good support to various sizes of placing sand block.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1, attachment base；2, sliding eye；3, placing sand block backing plate；4, shim；5, top flat；6, addendum cone block；7, it slides convex
It rises；8, lug boss.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
As shown in Figure 1, the utility model is a kind of placing sand block in self-hardening sand casting control chill gap, including a connection
Seat, the attachment base internal environment array are provided with several sliding eyes, and the sliding eye is flat structure, in the attachment base
Portion is provided with the press hole being connected to between each sliding eye, and the both ends in the press hole have been connected through a screw thread addendum cone block, institute
It states addendum cone block and adopts and be made of a steel, the circular conical surface of end is formed using self-hardening resin sand molding；It is slidably connected in the sliding eye
There is placing sand block backing plate, the placing sand block backing plate is formed using resin self-setting sand moulding, and one end of the placing sand block backing plate is provided with
One top flat for contacting with addendum cone block, the other end of the placing sand block backing plate are provided with a width and attachment base thickness phase
Same shim；The width of the shim and top flat is greater than the width in the middle part of placing sand block backing plate, the sliding eye inner wall setting
