Abstract
The utility model relates to a grinding section casting mould. A model mould board with two surfaces is additionally arranged between an upper casting sand box and a lower casting sand box. The upper surface of the mould board is designed with a pouring system and the lower surface is designed with a plurality of rows of grinding section patterns. An inner pouring path and a mould cavity adopt the pouring opening with pressing edges. The upper sand box, the lower sand box and the mould plate are designed with a positioning device used for connecting the three components. The grinding section quality can be guaranteed, the set casting technology is realized and the production efficiency can be increased.
Description
The utility model relates to a kind of mill section casting mould, can realize group's casting of all kinds of specification mill sections with it.
The mill section is the widely used grinding-materials of industry such as building materials, mine, electric power, and its volume is little, and structure is cylindrical.Present its version of known mill section casting mould is more, and representational roughly have two classes; One class is the permanent mold casting mould, the physical dimension that generally is rubbing section on bar shaped cast iron is beaten blind hole and is formed mould, molten iron directly waters and form the mill section in blind hole, the mill section that adopts this mould to produce, do not hold the pyramidal structure of nature formation because of drill bit in the Mould Machining process, make the tapered structure of mill segment trailer, head produces casting flaws such as " fleshiness " or misrun because of pouring technology, influenced the presentation quality and the serviceability of product; Another kind of is the sand casting mould, this class mould roughly has two kinds, a kind of is sand mold running roller casting mold and sand mold moulding mould, the former production efficiency height, but still adopt the fleshiness defective of " casting in open technology " so product head still can not avoid, several of general one case castings of the latter, productivity ratio is low or easily cause casting flaw such as mould shift because of minute mould is unreasonable.
The novel purpose of this use provides a kind of mill section casting mould, and it not only can guarantee the physical dimension and the presentation quality of the section of mill effectively, and can realize group's casting technology of its all kinds of specification mould mill sections, increases substantially production efficiency.
The purpose of this utility model is achieved in that between cope and drag box and accompanies template.Design has many row's mill section apperances below the template, designed running gate system above, the both sides of its ingate form certain overlapping with following adjacent apperance, promptly form kiss gate, the both sides design of template has locating aperture, and the cope design has alignment pin, and the drag box design has the location box, by alignment pin, locating aperture and location box cope, template and drag box are bound up during work, form a cover mill section moulding mould.
Owing to adopted such scheme, just can guarantee the geometry and the presentation quality of the section of mill effectively, realize its group casting technology easily, enhance productivity.
Below in conjunction with drawings and Examples the utility model is further specified
Fig. 1 is the part sectioned view of the utility model embodiment
Fig. 2 is the A-A cutaway view of Fig. 1
Fig. 3 is the B-B cutaway view of Fig. 1
1. copes, 2. templates, 3. alignment pins, 4. sprues, 5. mould running channels, 6. ingates, 7. mill section apperances, 8. flask handles, 9. drag boxs, 10. location box 11. Template Location openings among the figure
In Fig. 1, go up the alignment pin (3) that design has a pair of symmetry at cope (1), alignment pin is firm on sandbox by wood screw.Template (2) is clipped in the centre of drag box.Template (2) following designed 4 rows (can be a many rows) mill section apperance (7), and mill section apperance (7) fixes (structure of joining part is omitted in the drawings) countersunk head by countersunk head wood screw and adhesive glue with itself and template (2) and partly is coated with flat with wax.The top running gate system that designed of template (2) contains sprue (4), cross gate (5) and ingate (6).Sprue (4) adopts manner with the connection of cross gate (5), and cross gate (5) is fixed on the template (2) with wood screw or adhesive glue with ingate (6).
Molten iron enters die cavity by running gate system and is realized by kiss gate, kiss gate is by the ingate (6) above the template (2) and following mould section apperance (7) formed intersection in the design between line-spacing and the width, it is the δ value among Fig. 3, the big I of δ is decided general desirable 5mm according to the specification of mill section.What of mould section stock layout, being no more than 400 * 350mm with the sandbox internal diameter size exceeds, and other sizes can be determined by technology.
Cope (1), template (2) and drag box (9) connect with a pair of location box (10) mutually by a pair of alignment pin (3), a pair of template opening (11), and the cooperation between navigation system can be selected the fit dimension that marks among the figure for use, and mating surface should be bright and clean.Cooperate the location for adapting to, the appearance and size of upper and lower sandbox is answered strict conformance; Go up drag box and all do and survive case for convenient unpacking, material can be selected dried birch and other weedtrees for use.Template is selected on-deformable extra dry red wine pine or bakelite plate for use.
Make top box after can making the nowel upset during moulding earlier, when making top box, should insert good sprue earlier.Sprue be should play earlier during molding, top box and transverse slat played again successively.After template trips out, by the navigation system mould assembling.In moulding and the mould assembling cast, mould section (7) and die cavity thereof are in the nowel all the time as can be seen, can guarantee mill section quality so preferably and prevent mould shift.
Claims (3)
1, a kind of mill section casting mould is characterized in that between the upper and lower sandbox of casting a match plate being arranged, and running gate system is arranged above the template, and 4 row's mill section apperances are arranged below.
2, mill section casting mould according to claim 1 is characterized in that alignment pin is arranged respectively on cope, template and drag box, locating aperture, location box, the connection and the location of being realized drag box and template by this three.
3, mill according to claim 1 section casting mould is characterized in that having formed casting kiss gate between ingate and adjacent mill section apperance line-spacing.
