Abstract

The utility model discloses a sand mould of a cylinder cover of an engine. A frame of a sand box is arranged on a bottom plate of the sand box, and a sand core of a body is arranged in the sand box formed by the frame of the sand box and the bottom plate of the sand box; and a functional sand mould is arranged above the sand core of the body. In the sand mould of the cylinder cover of the engine, a simple sand mould of a cylinder cover of an engine is formed by the simple sand box comprising the frame of the sand box and the bottom plate of the sand box and the functional sand mould arranged above the sand core of the body; the manufacturing process is simple, and an exterior mold does not need to be used; the manufacture of the sand mould of a sample of the cylinder cover at the trial-manufacture stage of the production can be flexibly disposed, the trial-manufacture efficiency of a sample component can be effectively enhanced, the trial-manufacture period of a product is shortened, and the normal production of a production line and the disposal of the manufacture of the sand mould of the product are also not influenced; and the use quantity of molding sand is little, and the cost is saved.

Description

A kind of engine cylinder cap sand mold
Technical field
The utility model relates to a kind of engine cylinder cap manufacturing technology, relates in particular to a kind of engine cylinder cap sand mold.
Background technology
The sand mold of engine cylinder cap is a kind of requisite intermediate products in the cylinder cap casting manufacture process.Sand mold is made the method for moulding, be in the cavity of external form mould with definite shape and sandbox formation, to fill the diffusing shape molding sand mixture that configures, make the moulding of bulk type sand mixture and reach certain degree of packing by pressure or other physical-chemical method, make it break away from external form mould afterwards and the sand mold that obtains having definite shape.
Common engine cylinder cap sand mold need be by the help manufacturing of external form mould and mo(u)lding equipment, and the sand mold that this method is made need rely on the pressure of mo(u)lding equipment to reach consolidation, and need realize moulding on flow production line by the external form die forming.Cylinder cap sample as advanced development is produced, and makes sand mold on streamline, must influence the production efficiency of whole piece flow production line, is unfavorable for realizing manufacturing experimently the short period requirement of part simultaneously.
The utility model content
The purpose of this utility model is, a kind of engine cylinder cap sand mold is provided, and makes that the manufacturing process of sand mold is simple, does not need to use the external form mould.
For achieving the above object, according to an aspect of the present utility model, provide a kind of engine cylinder cap sand mold, upset frame is placed on the moulding plate, puts into the body core in the sandbox of upset frame and moulding plate formation; Above the body core, be provided with the function sand mold.
Wherein, be filled with the protection sand mold in the cavity between body core and the sandbox.
Function sand mold and protection sand mold are self-curing mo(u)ld.
Described function sand mold cooperates by tenon with the body core, and is by fastening screw that function sand mold, body core and sandbox is fastening.
Be provided with the sprue of vertical arrangement, cross gate and connection body sand mold and the extraneous steam vent that level is arranged in the described function sand mold.
Engine cylinder cap sand mold of the present utility model, formed a simple engine cylinder cap sand mold by simple and easy sandbox of forming by upset frame and moulding plate and the function sand mold that is arranged on body core top, manufacturing process is simple, need not use the external form mould; Can arrange production the flexibly sand mold manufacturing of advanced development cylinder cap sample can effectively improve the trial-production efficient of sample spare, shortens the trial production cycle, and does not influence streamline ordinary production product and make the sand mold arrangement; The molding sand use amount is few, saves cost.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, the utility model engine cylinder cap sand mold comprises:
Moulding plate 1, upset frame 2, body core 3 and function sand mold 5, sandbox is made up of moulding plate 1, upset frame 2, and this sandbox is sand frame and the separable structure of moulding plate.Upset frame 2 is placed on the moulding plate 1, puts into body core 3 in the sandbox that upset frame 2 and moulding plate 1 form; Above body core 3, be provided with function sand mold 5.
Wherein, as shown in Figure 6, body core 3 is used to form the internal structure and the outer contoured shape of cylinder head product.
Preferably, be filled with protection sand mold 4 in the cavity between body core 3 and the sandbox.Protection sand mold 4 be distributed in body core 3 around, molten iron overflows or spill from the body core night after being used for preventing cavity filling process and filling type, avoids the safety of molten iron liquid to operating personnel around the erosion of upset frame and the protection to reach.
Function sand mold 5 and protection sand mold 4 are self-curing mo(u)ld.
Wherein, as Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 7, function sand mold 5 is provided with tenon 10, and the body core is provided with corresponding tenon seat, but tenon 10 and corresponding tenon seat contraposition cooperation, with positioning function sand mold 5 and body core 3; Function sand mold 5 cooperates with tenon 10 by the tenon seat with body core 3, and function sand mold 5 cooperates by tenon 10 and tenon seat with body core 3, and is by fastening screw 6 that function sand mold, body core 3 and sandbox is fastening.Realize rapid and precise assembly operation.
Be provided with the sprue 7 of vertical arrangement, cross gate 8 and connection body sand mold and the extraneous steam vent 9 that level is arranged in the function sand mold 4.Wherein, sprue 7, cross gate 8 are to be used for water conservancy diversion and the shunting of molten iron at cavity filling process; Be used for arranging the gas of cavity filling process body core 3 generations and the chill water liquid that cavity filling process produces at steam vent 9.
The engine cylinder cap sand mold of present embodiment, manufacturing process is simple, need not use the external form mould; Can arrange production the flexibly sand mold manufacturing of advanced development cylinder cap sample can effectively improve the trial-production efficient of sample spare, shortens the trial production cycle, and does not influence streamline ordinary production product and make the sand mold arrangement; The molding sand use amount is few, saves cost.
It should be noted that: above embodiment is only unrestricted in order to explanation the utility model, the utility model also is not limited in above-mentioned giving an example, all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
