Description

Cylinder mould
Technical field
The utility model relates to a kind of mould, concrete, relates to a kind of cylinder mould.
Background technology
At present, the cylinder block of general small displacement engine is all to adopt high-pressure casting mode to produce, under high pressure filling, pressurize, after cooling, can make cylinder block be connected with the seam of steel bushing very tight, can meet quality requirement, but high-pressure casting does not reach again the air-tightness requirement of foundry goods.
As shown in Figures 2 and 3, while adopting the engine cylinder block that the mode of low pressure casting produces, cylinder block is aluminium material, cylinder sleeve is spheroidal graphite cast-iron material, because the cooling velocity of cylinder block is slower than the cooling velocity of steel bushing, the blank cylinder block 4 of moulding by casting easily produces gap with the region A that the seam crossing of steel bushing 7 contacts with air, is connected not tight, and the qualification rate of the finished product cylinder block after processing only has 20~30 ﹪.
Utility model content
In prior art, the engine cylinder block that the mode of employing low pressure casting is produced, cylinder block easily produces gap with the region that the seam crossing of steel bushing contacts with air, be connected not tight, the low technical problem of qualification rate of the finished product cylinder block after processing, the purpose of this utility model is to provide a kind of cylinder mould, this mould by arranging cannelure on patrix mold insert, solve cylinder block and easily produced the technical problem in gap with the region that the seam crossing of steel bushing contacts with air, greatly improved product qualified rate.
To achieve these goals, the technical solution of the utility model is:
A cylinder mould, comprising: upper die and lower die,
Described counterdie comprises: low mold frame, be arranged on the lower mold core in low mold frame; Be arranged on left slider seat and the right side take-up housing of lower mold core both sides; In described left slider seat and right side take-up housing, be respectively arranged with left slider and right side slide block; The bottom of described lower mold core is provided with sprue bush;
Described patrix comprises: upper framed, be arranged on the upper mold core in framed; Describedly also be provided with feet, ejector retainner plate and thimble cover plate on framed; The bottom of described upper mold core is provided with patrix mold insert, and patrix steel bushing locating piece is arranged on the bottom of described patrix mold insert and is connected with patrix mold insert; On patrix steel bushing locating piece, be set with steel bushing;
The lower plane of described patrix mold insert contacts with the end face of steel bushing, on this lower plane, is provided with cannelure.
Useful technique effect of the present utility model is:
Cylinder mould of the present utility model, by patrix mold insert, cannelure being set, when cast, aluminium liquid flows in cannelure, thereby the top of the blank cylinder block of moulding by casting is covered the part parcel at steel bushing top.After cylinder block is cooling, in the gap of cylinder block and the generation of steel bushing top, after machined, this gap does not affect the product quality of cylinder block, has greatly improved product percent of pass, and product qualified rate reaches more than 95%.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further details.
Fig. 1 is structural representation of the present utility model, and as shown in Figure 1, cylinder mould of the present utility model, comprising: upper die and lower die,
Described counterdie comprises: low mold frame 1, be arranged on the lower mold core 2 in low mold frame 1; Be arranged on left slider seat 6 and the right side take-up housing 15 of lower mold core 2 both sides; In described left slider seat 6 and right side take-up housing 15, be respectively arranged with left slider 5 and right side slide block 14; The bottom of described lower mold core 2 is provided with sprue bush 16;
As shown in Figure 1, described patrix comprises: upper framed 10, be arranged on the upper mold core 9 in framed 10; On described framed 10, be also provided with feet 11, ejector retainner plate 12 and thimble cover plate 13; The bottom of described upper mold core 9 is provided with patrix mold insert 8, and patrix steel bushing locating piece 3 is arranged on the bottom of described patrix mold insert 8 and is connected with patrix mold insert 8; On patrix steel bushing locating piece 3, be set with steel bushing 7.
As shown in Figure 6, the lower plane 81 of described patrix mold insert 8 contacts with the end face of steel bushing 7, on this lower plane 81, is provided with cannelure 82.
While utilizing cylinder mould of the present utility model to adopt the engine cylinder block that the mode of low pressure casting produces, aluminium liquid is from sprue bush 16 enters, be filled in the cannelure 82 of patrix mold insert 8, as shown in Figure 4 and Figure 5, the top of the blank cylinder block 4 of moulding by casting covers the part parcel at steel bushing 7 tops.After cylinder block is cooling, the seam crossing at the D place in Fig. 5, owing to contacting with air, can produce gap, but carries out after machined as the machined finished product dimension line R along in Fig. 5, and this gap does not affect the product quality of cylinder block, and last finished product is certified products.Utilize the blank cylinder block of engine cylinder block die casting of the present utility model moulding, after carrying out machined, product qualified rate can reach more than 95%, greatly reduces production cost.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
