Abstract
Piston ring sand mold, belongs to the making field of piston ring.Comprise multiple sandbox stacked successively from bottom to top, the geometric center position of the sandbox of the top is provided with the conical through-hole as cup, and the big opening end of conical through-hole upward.The utility model manually digs out cup by template frame on the uppermost sandbox of sand mold, meet production requirement, easy and simple to handle, do not take dedicated site to make, do not need the cup ironcasting making easy loss specially, without the need to swabbing, do not need special messenger to collect, clear up yet, take and manually significantly reduce; The blank percentage of A-class goods is unaffected.
Description
Technical field
The utility model belongs to the making field of piston ring, is specially a kind of piston ring sand mold.
Background technology
In Foundry Production, the die cavity that liquid metal enters moulding need offer passage in casting mold, and this passage is running gate system, comprises cup, sprue, cross gate and ingate.The normally funnel shaped pouring basin of cup, manufactures separately or is directly formed in casting mold, and the molten metal from casting ladle is accepted in its effect, is convenient to cast, reduces molten metal to the direct impact of casting mold, can skimming, raising molten metal static pressure.
Piston ring blank produced by existing piston ring multiple mould, and need to make cup separately, its weak point is: (1) needs to make cup specially; (2) making form can divide two kinds: one to be cast iron cup dip-coating material, and two is that special messenger makes tide mould sand cup; (3) need special messenger to put and clear up; (4) cup metals run out sometimes with top case.
Thus, the existing cup manufacturing process cycle is relatively long, and cost of manufacture is high.
Utility model content
It is simple, easy to use that the purpose of this utility model is to provide a kind of making, can efficiently solve the piston ring sand mold carrying cup of above-mentioned defect.
The technical scheme realizing above-mentioned purpose is: piston ring sand mold, comprises multiple sandbox stacked successively from bottom to top, it is characterized in that:
The geometric center position of the sandbox of the top is provided with the conical through-hole as cup, and the big opening end of conical through-hole upward.
The manufacture craft of above-mentioned sand mold is:
(1) making stacks by multiple identical sandbox the sand mold formed;
(2) make and sandbox template frame of the same size, the geometric center position of template frame is provided with the tapered die identical with cup shape;
(3) take off the uppermost sandbox of sand mold, the sandbox taken off is overlayed on template frame, according to the mould tapered die shape on template frame, produce cone-shaped gate cup being positioned on the sand mold above template frame;
(4) be again stacked in the top of sand mold after being turned upside down by the sandbox that cone-shaped gate cup is set, and the big opening end of cone-shaped gate cup upward.
The utility model manually digs out cup by template frame on the uppermost sandbox of sand mold, meet production requirement, easy and simple to handle, do not take dedicated site to make, do not need the cup ironcasting making easy loss specially, without the need to swabbing, do not need special messenger to collect, clear up yet, take and manually significantly reduce; The blank percentage of A-class goods is unaffected.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model comprises multiple sandbox 1 stacked successively from bottom to top, and the geometric center position of the sandbox 1 of the top is provided with the conical through-hole 2 as cup, and the big opening end of conical through-hole 2 upward.
